Twin Turbo EFI 302

Turbo / Intercooler Install

10-19-03

From the top we can see the completed system as fabricated here by Jim Sheren. It is somewhat similar to Crazy Joe's twin setup with the exception of the intercooler outlet here which did not require cutting of the radiator support.

In the details here you can see the cutting and rewelding of the turbine outlet which makes for an easy install in these fox body cars. The Compressor outlet is directed down thru the inner fender section to the intercooler out front. Schedule 10 stainless was used for all of the hot side plumbing.

The intercooler was up next. This is one of Jim Sheren's fox body coolers which is pretty much the biggest cooler you can fit without major modification to the vehicle. As you can see it fits behind the bumper mounts so the stock bumper can still be reinstalled if desired. Eric's street car will be more strip oriented so he decided to leave the bumper off and maximize the flow thru the cooler core.

The details of the cooler piping are fairly simple. The factory 2.3L turbo compressor outlets were used and then connection pipes from J-Bends were fabricated to get the hot compressed air to the intercooler. The larger 3" pipe is carrying the cooled air to the throttle body.

Since Erics' car is running an AEM EMS with MAP sensor, not MAF meter is needed. If this was a MAF based system, I would have placed the MAF meter in the 3" pipe where the blue connection band is located inside of the fender as shown in the photo.

Finally a top view shows the location of both turbos. All that's left now is to complete the fuel system and start tuning. Eric's goal was a sleeper that he could drive to the track and run high 10's, I'm looking forward to see how this ends up, my guess is that he will get more than he bargained for.
