Spartan, I order to maximize core size and have a good flowing end tanks you need to convert to the NA throttle body and center plenum. I'm working on the details for my future IC build. You need Pt# 993 110 128 11 for the TB and 993 110 027 03 for the connecting piece. You will need to relocate the ICV as well. I haven't done this yet and I sure I will come across several minor re pluming issues. What are people doing about the heater box.

Can someone verify the size of the gt2 core for me. I think they are 9x12x3?

here's a link that shows how the back side of the intercooler connects. It's on page 2

V= You need to use the GT2 tail,won't fit under the std.tail.
Tacker= You can use the stock tt manifold,it is the same as the na manifold.
Ok, some quick details:
Outlet of intercooler goes directly to a "Y" shaped plenum.,this connects to a 993 RSR intake manifold,the manifold sits at the top of 6 993 RSR Itb's.,engine mechanicals are the usual 993 GT2 bits.(with the exception that is a 3.8 ltr. capacity) Engine was making 800hp @1.3 bar.,going to test this weekend,lets see what happens with the new intercooler cores,I feel at least 50 more hp.(thru my pants that is!).

Hi just went out an measured 8 3/4 x 13 1/4 x 3 1/4.

ahh
sounds like there are some options with how to set up the intake...

Hi Basal I'm a new member to the site and I do have a 993 TT with Garret's 28 and I'm hunting for an inter cooler the stock isn't that good I hear I have about 540hp on wheels with a guard LSD I also installed the cargraphic oil cooler and PSS10 blistering that I love I have been to the track and unfortunately my brakes overtemped but I did very good lap times. Do you have any different ignition? I'm thinking of installing the crane cd with the L92 coil do you have any experience with that?

thanks for the dimensions

I wonder if any air is making it to the center IC. It might be hard to cut the IC's to fit deeper end tanks but I bet it'd improve efficiency.

sonny1

You can't see the tanks, they are deep enough under the cooler.Air gets in there pretty evenly.

V

You mean like this? (see pic)

In the picture, are the end tanks separated by the weld in the middle or is it one big end tank?

I think deeper end tanks are possible but the problem is that the rear wing has to be modified to fit... Apparently the standard turbo wing is smaller on the inside compared to the GT2 wing. I didn't know this, I thought they were identical.. I suppose that with the GT2 wing the grill sits higher = more volume in the engine compartment. I've heard from "sonny1" that his setup won't work with the standard wing so I'm guessing the I/C sits so high in the engine bay that the normal turbo wing won't close completely..

Acropora

Ah, I see. Thanks for the info guys. If it can be made to fit under a stock wing I'm in!

+1

I'm guessing the end tanks look something like this? (see pic)

sonny1

Kind off, mine are much bigger than that,the gt2 cores are much bigger and thicker than the Griffins.

Hi Pilot, welcome to Rennlist!
Sounds like you have a well set up car.
Others may be able to comment, my ignition is stock - just an aftermarket ecu/5bar fuel pressure regulator/turbos/cats/DIY oil cooler(I have a thread on that too!)/this Intercooler/motons/ERP/tarret suspension bits/tilt kit/Guard LSD/? might be forgetting something...
I've seen different ignition in other/older porsches but not in our cars? Most people just use stock parts and do the twin plug thing.

V - is that a protmotive intercooler? is it made to fit the stock throttle body? how do you get to/tighten the centre bolt on the intercooler/throttle body connection?

Brad - if I ever get around to making a version 2, I'll try and see if it can made to fit the stock wing. Or someone else can try. I keep fantasizing about building an engine (DIY of course but to do so I would need a spare motor so I can take my time - but they're kind of expensive), that ?sportec motor on Kevin's old thread looks pretty nice...

Here's my setup (just finished it last night) using 2pcs GT2RS coolers welded together. The engine is a stock varioram 3.6 (less the varioram now) with a Eaton M90 supercharger, max 0.5bar boost. Stock compression (yikes!!!) abt. 400hp/450Nm. I have 400Nm from 2,000rpm to redline, so I'd say the power is quite useable...

I had a water/air intercooler system but it was not up to the task at track so I followed Basall Skulls footsteps and ordered these GT2RS coolers.

Tomorrow will be the first test at a local track, I am hoping I have solved the issue with rising IAT's now...

With regards to the ignition, I went distributorless. I used 2pcs Bosch wastespark coils and Bosch amps. The motor was originally a twin plug (and still is) It works like a charm!

Hello

I was also considering the crane system to increase the spark energy while keeping the stock motronic. This has apparently been used on these cars a number of times before by protomotive and others with good results. The coil fits in the stock location (one hole needs to be changed) and the CDI box can be screwed to the shelf behind the rear light and so hidden away for a stock look.
I bought all of the bits but they are still brand new in box as I have the engine and loom out and so am considering going full aftermarket ecu with coil on plug.
For reference, Crane recommended the 6000-6440 (which is the Hi-6 with weatherpack connectors), and thought the Lx91 would be better than the lx92
and so recommended 730-0891
