00:00:00.460 [Music] 00:00:01.38900:00:01.399 as welcome to the video we're at kids be 00:00:04.07000:00:04.080 performance if you see the car here we 00:00:06.32000:00:06.330 got everything laid out we're working on 00:00:07.70000:00:07.710 the HKS oil cooler Dylan so everything 00:00:10.58000:00:10.590 up Dylan's new here what's going on my 00:00:12.02000:00:12.030 are you from how do you Phoenix 22 okay 00:00:14.48000:00:14.490 cool oh we're the same age that's right 00:00:15.82900:00:15.839 I thought you're a little older but yeah 00:00:18.17000:00:18.180 so we're gonna pop the hood Cody's back 00:00:19.70000:00:19.710 over there and we'll get started and 00:00:21.62000:00:21.630 show you what's up but this is the JDM 00:00:23.26900:00:23.279 spec model of this color we've got to 00:00:26.59900:00:26.609 make sure it'll fit the USDM spec and 00:00:28.97000:00:28.980 then let HKS know if any changes need to 00:00:31.16000:00:31.170 be made but to be fun process and let's 00:00:33.53000:00:33.540 get into it 00:00:36.53000:00:36.54000:00:54.86000:00:54.870 we ran into a couple issues Joe here 00:00:57.56000:00:57.570 you've seen before Joe explain to us 00:00:59.02900:00:59.039 what's going on the we rent a couple of 00:01:01.61000:01:01.620 issues here the oil cooler actually gets 00:01:03.92000:01:03.930 mounted in this area here obviously we 00:01:07.73000:01:07.740 have an intercooler pipe to deal with 00:01:09.58000:01:09.590 HKS makes a really cool ductwork system 00:01:13.10000:01:13.110 that actually comes through here and 00:01:15.77000:01:15.780 actually wraps around this way and it's 00:01:18.38000:01:18.390 kind of in the way of this pipe as well 00:01:20.17000:01:20.180 so what we're gonna do is we're gonna 00:01:22.88000:01:22.890 take the pipe off we're gonna take the 00:01:24.77000:01:24.780 intercooler off we're gonna fit the oil 00:01:26.38900:01:26.399 cooler run everything get it all fit and 00:01:29.54000:01:29.550 then we're going to remake this pipe to 00:01:32.21000:01:32.220 work around the oil cooler bracketry and 00:01:37.81000:01:37.820 ductwork and it should be pretty cool 00:01:41.12000:01:41.130 also in Japan on the STI s they use at 00:01:44.24000:01:44.250 winch we'll set up so the the actual 00:01:47.74900:01:47.759 exhaust manifold is set up differently 00:01:50.59000:01:50.600 this oil cooler was set up for that 00:01:54.46900:01:54.479 twin-scroll exhaust manifold set up here 00:01:57.62000:01:57.630 in the u.s. we only get a single scroll 00:01:59.09000:01:59.100 so this portion in here is different so 00:02:02.09000:02:02.100 we're probably gonna have to modify this 00:02:03.56000:02:03.570 heat shield to work with this with this 00:02:07.10000:02:07.110 oil cooler not a big deal just something 00:02:09.91900:02:09.929 that we're gonna have to work around in 00:02:12.94900:02:12.959 Japan they actually have you modified 00:02:14.93000:02:14.940 the heat shield around their around 00:02:18.41000:02:18.420 their exhaust manifold as well so they 00:02:21.44000:02:21.450 got to do it in Japan looks like we have 00:02:22.88000:02:22.890 to do it in the u.s. also gameplan we're 00:02:25.43000:02:25.440 gonna lower it put it on and then figure 00:02:27.65000:02:27.660 out what kind of new intercooler pipe 00:02:29.90000:02:29.910 John can make to make the front mount 00:02:32.69000:02:32.700 fit because people don't normally run 00:02:34.28000:02:34.290 front mounts in Japan I was told they 00:02:36.11000:02:36.120 kind of keep things a lower horsepower 00:02:37.40000:02:37.410 of all about handling driving experience 00:02:39.11000:02:39.120 us over here different stories so most 00:02:42.11000:02:42.120 people are running ETS or pairing for my 00:02:43.97000:02:43.980 intercooler and you're gonna need a new 00:02:46.67000:02:46.680 pipe so that's what we got to figure out 00:02:57.95900:02:57.969 this is the nightmare of hardware and 00:03:00.78900:03:00.799 everything's in Japanese so who knows 00:03:03.09900:03:03.109 where it all goes 00:03:13.58900:03:13.599 any comments are concerned someone 00:03:15.97000:03:15.980 putting this together like you did with 00:03:17.47000:03:17.480 the jigsaw puzzle it's be patient their 00:03:23.14000:03:23.150 pictures don't explain very much and 00:03:25.80900:03:25.819 that's all in Japanese so you got a he 00:03:28.05900:03:28.069 kind of just gotta figure it out as you 00:03:29.71000:03:29.720 go it took me 45 minutes to figure out 00:03:36.19000:03:36.200 how to put all these pieces of metal 00:03:37.36000:03:37.370 together 00:03:42.83000:03:42.84000:03:59.01000:03:59.020 let me find out about the book so my 00:04:02.50000:04:02.510 dump it was reading trying to read 00:04:05.65000:04:05.660 Japanese when the second half of its in 00:04:08.02000:04:08.030 English read the whole book before you 00:04:10.90000:04:10.910 start trying to 00:04:13.62000:04:13.63000:04:21.15900:04:21.169 and we got the hoses ran they're not the 00:04:27.08000:04:27.090 way that HKS tells you to do it but 00:04:29.48000:04:29.490 their way is not gonna work with already 00:04:30.95000:04:30.960 header so we just kind of took their 00:04:34.25000:04:34.260 lines and made them work you Jill 00:04:36.53000:04:36.540 homeless no I just cut it out with the 00:04:38.60000:04:38.610 razor blade oh it's pretty good yeah I 00:04:41.27000:04:41.280 got pretty lucky like this right this 00:04:50.51000:04:50.520 look this dude we don't even have to do 00:04:52.15900:04:52.169 anything 00:04:52.58000:04:52.590 look that's that's gonna be I mean it 00:04:54.71000:04:54.720 might be a little bit of a leak but 00:04:55.90900:04:55.919 that's fine yeah see right there just 00:05:00.14000:05:00.150 dude 00:05:01.93000:05:01.940 and that'll be okay we might have to 00:05:03.49000:05:03.500 trim the hood out send it I think it's 00:05:08.83000:05:08.840 gonna be fine i intercooler through the 00:05:11.68000:05:11.690 hood no no just the piping for it all 00:05:14.59000:05:14.600 the pipe I mean for the intercooler 00:05:16.06000:05:16.070 there that's just stupid run the pipe 00:05:18.04000:05:18.050 and then trim this down 00:05:20.62000:05:20.630 okay this is where we are now you see we 00:05:24.52000:05:24.530 have the the oil cooler on it's all 00:05:28.12000:05:28.130 installed all Plumbing's done underneath 00:05:29.86000:05:29.870 I know you've seen that next thing we're 00:05:31.90000:05:31.910 going to do is modify this ductwork a 00:05:33.94000:05:33.950 little bit finish this inner core pipe 00:05:36.67000:05:36.680 it's actually gonna work out a little 00:05:38.26000:05:38.270 bit better he's gonna have a little bit 00:05:39.55000:05:39.560 shorter inner cooler run which is gonna 00:05:41.71000:05:41.720 help throttle response he'll performance 00:05:43.75000:05:43.760 so we'll finish this up and then we'll 00:05:46.77000:05:46.780 we'll show you what it looks like when 00:05:48.46000:05:48.470 we're finished it's the next day 00:05:49.47000:05:49.480 holy moly John murdered it before we get 00:05:54.46000:05:54.470 in the details I'm gonna go grab him and 00:05:55.96000:05:55.970 let him explain everything he did I'm so 00:05:57.85000:05:57.860 thankful for the guys here they knocked 00:06:00.13000:06:00.140 it out of the ballpark to make this work 00:06:01.75000:06:01.760 on this car and I've never had that I 00:06:04.18000:06:04.190 told John over text and he sent me 00:06:05.53000:06:05.540 photos that do I've never had anything 00:06:06.67000:06:06.680 custom I feel very very special and 00:06:08.47000:06:08.480 thank you so much but let's go grab you 00:06:11.05000:06:11.060 want to talk about you're making this 00:06:13.18000:06:13.190 car look like it doesn't even need a 00:06:14.44000:06:14.450 front bumper well I can talk about how I 00:06:16.99000:06:17.000 fixed your situation of wanting to run 00:06:19.66000:06:19.670 that really cool HKS oil cooler kit and 00:06:22.86000:06:22.870 not being able to because of your front 00:06:25.15000:06:25.160 mount I can talk about that yeah please 00:06:27.22000:06:27.230 we all on all years we want to hear how 00:06:30.22000:06:30.230 you made this happen oh it's pretty 00:06:32.08000:06:32.090 simple really we just had to divert the 00:06:34.45000:06:34.460 path of your intercooler charge pipe 00:06:36.31000:06:36.320 well blunt when it shows up close well 00:06:38.26000:06:38.270 I'm trying to but you're not pointing 00:06:39.67000:06:39.680 I'm ready to go alright so this is 00:06:42.01000:06:42.020 pretty pretty simple so you put the HKS 00:06:46.00000:06:46.010 oil cooler on the car which is a 00:06:47.59000:06:47.600 fantastic piece by the way but 00:06:49.93000:06:49.940 unfortunately they don't design this oil 00:06:52.75000:06:52.760 cooler to work with a front mount 00:06:55.39000:06:55.400 intercooler and of course we've got this 00:06:57.40000:06:57.410 nice big front mount intercooler 00:06:58.90900:06:58.919 we can't we can't not use it so what we 00:07:02.20900:07:02.219 did is instead of the parent pipe 00:07:05.30000:07:05.310 running down kind of through here and 00:07:07.93900:07:07.949 then directly into the intercooler I 00:07:10.18900:07:10.199 fabricated out of some pretty tight 00:07:12.95000:07:12.960 radius mandrel aluminum pipe that I had 00:07:15.67900:07:15.689 this this this pipe that runs kind of 00:07:19.49000:07:19.500 underneath the headlight but yet over 00:07:22.52000:07:22.530 the HKS oil cooler so that way we could 00:07:26.68900:07:26.699 utilize every last bit of this airflow 00:07:29.39000:07:29.400 that's going to be going in this 00:07:31.18900:07:31.199 actually did a couple things that were a 00:07:33.11000:07:33.120 benefit over the stock parent is not 00:07:35.01900:07:35.029 only did it allow us to use the HKS in 00:07:38.86900:07:38.879 its unmodified form but we also saved 00:07:41.83900:07:41.849 about two foot of piping which is going 00:07:45.32000:07:45.330 to be a dramatic increase in our 00:07:48.76900:07:48.779 decrease and how long our charge by this 00:07:50.70900:07:50.719 so now we go from basically here where 00:07:53.99000:07:54.000 the parent light leads off we go into 00:07:56.71900:07:56.729 the pipe that I built underneath the 00:07:59.74900:07:59.759 headlight and then here re-entering into 00:08:05.05900:08:05.069 the parent elbow that goes into 00:08:09.12900:08:09.139 Accor ended up working out nice 00:08:12.57000:08:12.580 designing it as simply was trying to 00:08:16.14900:08:16.159 find the right bends and the minimal 00:08:20.11000:08:20.120 amount of space a lot of time and 00:08:21.96900:08:21.979 working once I got it kind of figured 00:08:25.11900:08:25.129 out tacked it all together set it in 00:08:27.12900:08:27.139 place made sure it was what good for one 00:08:29.11000:08:29.120 final fit and finished welded that's all 00:08:31.33000:08:31.340 done and it works perfectly and all of 00:08:33.61000:08:33.620 this here is all the factory HKS kit 00:08:38.62000:08:38.630 that we didn't have to modify well Cody 00:08:40.75000:08:40.760 said he had to cut this here um we cut 00:08:43.08900:08:43.099 it a little bit mostly just so that way 00:08:46.18000:08:46.190 we didn't have to modify your bumper and 00:08:49.98000:08:49.990 but normally we probably could have laid 00:08:52.87000:08:52.880 that in front of this a little bit but 00:08:55.38900:08:55.399 it just kind of looked a little bit 00:08:56.43900:08:56.449 cleaner if we if we trimmed just that 00:08:58.72000:08:58.730 there's just a little tab off of it but 00:09:01.12000:09:01.130 all of this is HKS as it comes and it 00:09:05.29000:09:05.300 worked out nice also a part of the kit 00:09:07.75000:09:07.760 is adding this mesh to the back of the 00:09:10.54000:09:10.550 splash guard and you had to cut it out 00:09:13.60000:09:13.610 but what's the good what's going on with 00:09:15.88000:09:15.890 that okay so the way this works is is 00:09:17.76900:09:17.779 that air comes in through here and with 00:09:21.69900:09:21.709 this kind of a box the HKS is made it 00:09:25.09000:09:25.100 jams the air through the oil cooler 00:09:27.10000:09:27.110 right well once that air has gotten 00:09:29.23000:09:29.240 through the oil cooler it has to go 00:09:31.03000:09:31.040 somewhere 00:09:31.54000:09:31.550 because if it doesn't have anywhere to 00:09:32.65000:09:32.660 go then it basically builds up a 00:09:34.56900:09:34.579 pressure area here and no more air can 00:09:36.69900:09:36.709 get in and over the oil cooler so they 00:09:39.34000:09:39.350 add this piece of mesh to the back here 00:09:41.07900:09:41.089 and what that does is it allows a place 00:09:43.38900:09:43.399 for that air that is now hot to escape 00:09:46.30000:09:46.310 and get out the back side of the fender 00:09:49.60000:09:49.610 liner Cody also showed me that on the 00:09:51.57900:09:51.589 back of at least this year he what would 00:09:55.54000:09:55.550 you call this John so this is the mesh 00:09:58.31900:09:58.329 material and so what we did is we shade 00:10:01.18000:10:01.190 this was blocked off basically thick 00:10:05.25900:10:05.269 plastic through here so on the front 00:10:06.63900:10:06.649 side it showed the mesh but on the back 00:10:08.19900:10:08.209 side it was blocked off on both of these 00:10:10.63000:10:10.640 sides so what Cody did is he went in 00:10:12.75900:10:12.769 they took and sanded this down to where 00:10:16.54000:10:16.550 it was 00:10:17.56000:10:17.570 past the blocked off part and then 00:10:19.81000:10:19.820 trimmed out all the holes so that way we 00:10:21.43000:10:21.440 have this nice diamond all the way 00:10:24.22000:10:24.230 across which not only helps air flow 00:10:26.29000:10:26.300 through here for the oil cooler but also 00:10:30.28000:10:30.290 shows the entire front mount intercooler 00:10:33.19000:10:33.200 as well and just looks really a lot 00:10:36.46000:10:36.470 better little bit nice the Subaru would 00:10:37.96000:10:37.970 have done that from the factory so this 00:10:39.97000:10:39.980 is a air intake temperature sensor and 00:10:43.00000:10:43.010 so we wanted to add that to your your 00:10:46.99000:10:47.000 kit and since I was building this pipe 00:10:48.82000:10:48.830 and we didn't want to mess up the powder 00:10:50.77000:10:50.780 coating for the rest of the kit 00:10:52.87000:10:52.880 I gave us a great opportunity to go 00:10:54.61000:10:54.620 ahead and put an air intake temperature 00:10:56.35000:10:56.360 sensor in there to the piper built 00:10:58.66000:10:58.670 normally and other kits was it Cody was 00:11:01.39000:11:01.400 telling me it would be close as close to 00:11:02.71000:11:02.720 the throwability as possible or what it 00:11:04.84000:11:04.850 can usually that's a lot of convenience 00:11:07.48000:11:07.490 you're kind of trying to get the 00:11:09.19000:11:09.200 temperature right as it goes into the to 00:11:11.62000:11:11.630 the motor but anywhere in the after 00:11:14.14000:11:14.150 intercooler is fine from from basically 00:11:17.41000:11:17.420 from this point right here where the air 00:11:20.20000:11:20.210 is coming out of the intercooler and the 00:11:21.91000:11:21.920 intercooler has done its job of cooling 00:11:23.56000:11:23.570 the air anywhere after that point is 00:11:25.96000:11:25.970 where really where you want that air 00:11:27.67000:11:27.680 intake temperature sensor technically in 00:11:30.58000:11:30.590 theory if you get it as close to where 00:11:34.15000:11:34.160 the the combustion chamber is that's the 00:11:37.03000:11:37.040 ideal point usually that ends up being 00:11:39.34000:11:39.350 somewhere around the throttle body but 00:11:42.13000:11:42.140 anywhere in the pipe from the 00:11:43.42000:11:43.430 intercooler to the engine as as 00:11:45.55000:11:45.560 perfectly I guess the the last thing 00:11:48.13000:11:48.140 that people might be questioning is why 00:11:50.50000:11:50.510 does this matter is because of this is 00:11:52.57000:11:52.580 so we can tune it on speed density which 00:11:54.64000:11:54.650 is the normal situation and you 00:11:56.71000:11:56.720 elaborate can you clarify that um yeah 00:11:59.59000:11:59.600 from what I understand you were wanting 00:12:01.51000:12:01.520 to switch over and you have to have that 00:12:04.24000:12:04.250 data input to to be able to run that 00:12:07.60000:12:07.610 kind of a setup if you're running speed 00:12:09.13000:12:09.140 density 00:12:11.30000:12:11.310 you only have a couple of parameters if 00:12:13.67000:12:13.680 you don't have a mass airflow sensor to 00:12:15.25900:12:15.269 be able to tell how much air is going 00:12:17.03000:12:17.040 into the engine then you're kind of 00:12:20.48000:12:20.490 short on parameters to be able to do 00:12:22.99900:12:23.009 that calculation adding the air intake 00:12:25.46000:12:25.470 temperature sensor gives you another 00:12:28.16000:12:28.170 piece of data for the ECU to calculate 00:12:30.92000:12:30.930 how much air is going into the engine it 00:12:34.34000:12:34.350 makes sense makes sense if you guys all 00:12:37.10000:12:37.110 understand you can comment below we can 00:12:38.38900:12:38.399 go into this more later but we're solved 00:12:41.60000:12:41.610 if you're still learning I understand so 00:12:43.79000:12:43.800 ask away but I understand it now so 00:12:46.85000:12:46.860 hopefully guys you do and I had him 00:12:47.80900:12:47.819 break it down a lot so well well you're 00:12:53.03000:12:53.040 very welcome 00:12:53.66000:12:53.670 I was a fun little project and I was 00:12:55.28000:12:55.290 happy to do it for you well I'll have to 00:12:57.17000:12:57.180 get this powder-coated eventually one 00:12:58.54900:12:58.559 day and get everything laced out and I'm 00:13:00.23000:13:00.240 super stoked to have something this 00:13:01.79000:13:01.800 trick on the car Oh 00:13:04.66000:13:04.67000:13:14.55000:13:14.56000:13:21.02000:13:21.03000:13:28.96000:13:28.970
