Default intercooling options

trying to figure out my options for better cooling. Doesnt seem like a wrx TMIC will fit, especialy if i dont take the strut bar off. Is there any upgrade to the ej20g that 2will take upwards of 300-350whp? I want to avoid Front mount so i dont have to hack the bumper, and have pressure drops while running it in its current condition. What about water to air??


Pics of the setup

Thanks,
Jet

I'm just working on putting an 04 WRX intercooler on my 93 GF8 - it looks like it will fit fine, I'm just having my machinist remove the stock BOV flange on it and trim the inlet pipe and then he's going to put a new BOV flange on the opposite side of the inlet tube for me so I can bolt an aftermarket BOV on.

It initially looks like it's going to fit quite well. I should have it done in the next week sometime.

^I have the same Ic for my car and was looking for ways to make it fit. Seems like the distance from the TB to firewall is going to be an issue as is the turbo to IC plumbing considering the 02+ WRX IC has dual inlets and ours only has one. What are you doing for this issue? Pictures or bust.

I'm putting on an 02 Y pipe

I'll take pics once the intercooler is modded. The firewall seems fine on my car after an initial look - I am shortening the intake tube and will do the throttle body if necessary (others that have done it say it doesn't need it).

I also have an EVO III TD05H-16G for an 02 up that I'm installing at the same time (Just using a silicone 90 to get past the top entry issue).

Nice I guess your car came with the TD04 hey, the wrx's came with the TD05 16g already. I think the EVO Turbo is a tiny bit bigger. My WRX IC came with the Y-pipe but its not long enough to mate to the turbo?

Yeah, mine had a TD04 originally - the EVO III 16G is supposed to be pretty close to an 18G in performance - not a worthwhile upgrade if you already have a 16G though......

The Y-pipe shouldn't be a big deal to match up - just buy some extra silicone tubing / elbows and extend it to where you want it.

i ended up getting an upgraded tmic for now. I do want to find the stock intercooler spray kit with the harness and everything needed to mount it in stock spot on dash. Does anybody know where this can be found?

Look half way down there is one used for sale.

Problem with the WRX Y is that its plastic and just the 2 elbows off the IC are aluminum. What is yours like?

FWIW I've been through a couple of IC options for my EJ20G and ended up getting a Ver 1/2 STi TMIC from eBay UK. AVO use to make a good bar & plate TMIC that flowed well (see this article). http://autospeed.com/cms/A_1618/article.html and you can still get the upgraded alloy feedpipe, but it is very expensive.

Like you I didn't want an FMIC, but my power goals are much lower than yours. From what I've been able to find, upgraded TMIC options for the Ver 1/2 EJ20Gs are limited. The Ver 3 TMIC wouldn't fit between the throttle body and firewall (without some serious firewall work). IMHO I think you are going to struggle seeing 300whp on one of the available TMICs.

Get an aftermarket silicone hose kit for the intercooler pipes and then you can cut it and insert an extension or even shorten it if necessary - the stock accordian hoses are crap anyway!

The 06-07 TMIC is thinner, more narrow, but longer. If you have a tight fitting under hood area this one is the trick. It has the plastic end tanks.

The whole HP limit and water to air thing is a whole nother issue that you can research. I have no experience in either but I can tell you that I am getting the above intercooler for my motor and I am shooting for the same power.

yea i ended up getting the ver1/2 sti tmic and pipes. From what the flow reports said, its more the pipes that come with it instead of the intercooler that allow it to flow so much better. Hope this helps a little, once i get it on to the dyno it goes! Can any of you guys tell me what color your stock ej20g injectors are? I know the builder of the can ran 660's at some point, i want to tell the tuner if its stock injectors or not.

So no go. I went to fit it and well since my car is RHD the clutch master is in the way of the IC. I am just gonna do a front mount. Anyone have a good place to find one for my car with the ABS module up front?

Were you trying to install it upside down to get around the BOV flange thing?

The intercooler mounts offset to one side and shouldn't really come near your master cylinder. Trust me, it will fit........

That's off scoobynet and was done on a 93 RA (note the extra fuel injector on top of the plenum).

http://bbs.scoobynet.com/private-sal...t-classic.html

Here's the installation description that goes with it

Quote:
Not really that much work to be honest. I have a blobeye WRX TMIC which I ran on my 93 RA for a while before fitting a front mount and appart from removing about 3mm from the throttle body inlet it fits straight on.
Having said that the dump valve flange has been removed and it has all the pipework to fit an external dump valve so all of the fabrication work required to the TMIC has already been done and all the pipe work tailored to fit.
But having fitted both there is more hassle involved fitting a front mount than fitting this. If you fit a front mount you have to cut the bumper, trim some metal from the front edges where the pipes run, cut a hole in the drivers side inner wing and if its an early classic cut and join the pipe that runs round the oil filler cap.
My machinist just took my intercooler and Blitz BOV from me today, but he's going to be on vacation next week, so it will be a couple of weeks before I get it back. He's custom modifying the flange on my BOV so it will just bolt straight on to the opposite side of the intercooler rather than having to plumb it into the Y-pipe like the stock one.

No not upside down. I know there is a offset. You can't see the master from this picture. It is right beside the IC just out of sight. I sat the IC in there and it wasn't lined up with the TB by about an inch and was hitting the heatsheild of the clutch master. I will try today and see again. I have already welded the BOV flange flat. I was thinking of welding the second inlet shut as well for a simpler routing of the plumbing.

PS is there a rubber gasket sealing the end tanks on this intercooler? I am worried about how much heat is require to weld aluminum?

Here is my solution for the JDM EJ20G swap in my ’91 Legacy SS. Stock BOV is welded up and new fitting added on the other side of the throttle body. For my Legacy I also had to trim down the clutch master cylinder reservoir. Edit: my TB is cut down about an inch for better firewall clearance and less bashing of the pitch stopper mount.

Don’t mind the messy temporary plumbing.

Okay so I got it figure just need to weld off the BOV and one of the inlets. The inlet elbow that is on the BOV side of the IC is the one I am using. It turns out that the Samco kit designed for the V1-2 Euro spec WRX will fit perfectly to this elbow and mate up to the turbo perfectly. Also the BOV elbow off of this samco kit is in the perfect position as well. Who would have thought it.

I wouldn't blank the inlet off if I were you, the two inlets flow quite a bit better.....
