gc8 intercooler upgrade...

[Carl M]

with not alot of research i went from a non-sti 2000 gc8 intercooler to a v7 sti intercooler and having a lil problem with a reservoir <in the pic> is this a possible upgrade or is there a better intercooler option for this upgrade?

[DacerX]

nice upgrade, but u could make a bracket that angled the intercooler so that it doesnt hit that

[Stoffa]

drain it, unbolt the clear part off then simply trim 20mm off the bottom, bam lowered!

Just use a v7/8 master cylinder they sit off to the side. Also not much of an upgrade with out scoop to suit if you dont already have one. The shroud keeps the air directed through the cooler.

[Carl M]

so the master cylinder would be a quick replacement without modifying? i intend to get a larger scoop too at some stage

[Stoffa]

yes staight swap but have a read of this, it explains the cutting down option

Thanks i\'ll look into that ...uncanny i thought that was my pic for a sec, but saw the shortened reservoir , thanks again..

Just done this a few weeks ago, Stoffas solution is simple, quick and works great.

Mine completed below.

For the record better to cut 2 or 3 times than cut to much off in my opinion. Have you sorted the coil pack clearance issues?

Also I used the stock Intercooler piping not an aftermarket y pipe so I had a mate weld 2 Inches on to the end of the IC piping at the turbo end to make it all sit better. Its still a bit tight.

I reckon the "bent" topped master cylinder is the best option.

Easier to fill it, stays cooler too.........Although not Soopercool................

[Johnnynz]

How does it stay cooler? Is it further away from the turbo or something?

[Carl M]

Cool Johnny, i will cut to check a few times, did you need to adjust the coil pack? i havnt noticed a problem yet but i guess this is common to do so with this upgrade and will be buying a silicone y pipe..just cause.Have you upgraded to a larger scoop or done something else?

[Carl M]

Soopersubaru>> have you got a pic of the bent setup, cant seem to find that option on google...cheers.

[Carl M]

oh johnny how did you go for the right hand side bracket? i dont understand how this works?

[Johnnynz]

I cut down the mounts on the Intake manifold but found I didn\'t get a lot more room because of how deep the Coil Pack sinks below the mounts. I am sure its an easy enough issues to get around depending on the BOV you use. I had to drop it down about 5 Mils to fit a v7 BOV. I am currently using an Atmo venting cheapy and the coil pack is kind of just sitting there until I can be bothered working on a better solution.

I am using a v8 STI scoop with the below splitter.

I was lucky enough to get the splitter thingy with my TMIC from Stoffa.

[Johnnynz]

Right hand side bracket I beat the s*** out of for hours with a hammer in a vice and still couldnt get it so I drilled out the bracket mount hole and hit it some more. I can grab a pic tomorrow for you.

Please note I am the most amateur mechanic ever and my solutions are often very Rangimods

- Edit - That is to say Passengers side.

Drivers side I used the old bracket and its just sitting on it currently, seems nice and tight, I will cut up peice of steel and drill it next week to secure it to the old Mount,

[Guest]

Cutting it better imo.

[Carl M]

Ahh got ya, the splitter is a standard v7/8? the width of the scoop is stil the same but more flow because of the mouth size yeh? have you noticed a power increase since the intercooler upgrade?

[Carl M]

Hey evowrx....is that a modified version of the cylinder?

[Johnnynz]

Drivers side sitting on the bracket... You cant see it but the cooler rests on it without bending the fins. Its going to get a nice metal joiner next week.

Passenger side, blury as sorry. As you can see I got it close then made a small Aluminum peice to connect bracket to IC. That will get a metal joiner next week as well.

Drilled out hole where passengers bracket attaches to the Intake Manifold.

As I said, probably not the prettiest but worked so far.

[Johnnynz]

Splitter looks to be custom, Stoffa would know better than me,

No power increase as such I don\'t think but much stronger on boost. Gone from ranging between .9 and 1 Bar to a solid 1.1 Bar all the time. I am off for a tune with my Link Tomorrow.

[Carl M]

Still looks good man!!

Wait with bated breath.

No thats a stock variant iirc.

[Johnnynz]

Forged Internals, VF22, Walbro Fuel Pump, V7 STI TMIC and a Link G4. I think thats all...
