you speak of lag, but a trunk mount has less piping than a front mount on a eclipse (if done correctly). you will never feel the lag of a trunk mount vs side mount.

Love Doctor

Are you sure, cause the Trunk mount piping I've seen have more bends than a question mark.

The throttle body inlet is facing towards the front of the car and the Trunk mount is behind it..... looks like a 90degree bend, ouch.

Love doctor, on my old Z31 my intercooler piping made 16 turns through the wheel wells and all over the place. I used to joke with Mattback that air leaving my turbo had to mapquest the intake manifold. The guy from miami who built the car totally sucked at piping.. HOWEVER. I spooled a T78 to 15psi by 3100 RPM despite 16 turns, and around 10 feet of piping....

Seriously, trunk mounts are simple as pie....

I would add a couple more things to your list:

550cc injectors
Fuel pressure regulator

They really won't be able to effectively tune it with out the fuel pressure regulator since you are using a AFM to meter the air. Stock intercooler should be fine, just get an 8" spal fan for it. You should be able to run 16psi safely. You will also eventually need a clutch. You can get used OEM supra injectors for pretty cheap.

Love Doctor

Ok I will add the injectors to my list, but I already have the Fuel Pressure Regulator... I just referenced it as FPR above.

Anyway, if its true about the piping on a the trunk mount IC.... I maybe interested in this again, but who can help me with the piping and the modification to my MR2 chassis? Who has done this and has the know-how?

its quite simple. only draw back to trunk mount is losing space and cutting up your car. but the plus is the surface area you get and the larger heat sink capability

MR2driver

There are several different ways to mount it in the trunk. Vertical on the floor, vertical near the lid, horizontal near the rear. Then just start measuring and drawing. You also need to pick a core. Once you get the intercooler itself, then you can start designing it. There are plenty of cheap ones on ebay. Try not to get one with squared off endtanks, though.

you could mount the ic underneath the truck too lol. Ive seen that done on a drag mr2 in Japan .oh btw you probably know this or have it done already , but youll want to get a bigger rail for those injectors, if not youll get a loss of pressure across the rail and have unequal fuel pressure because the rail is so restrictive for the amount of fuel your trying to displace . It literally will have a few lbs of pressure difference at higher boost . Theres a big sticky on the mr2 about using 550s with the stock rail.fwiw

MR2driver

On that note, I have a factory fuel rail for sale for $40. You would just need to then get it bored out at a machine shop.

you can have it bored to 7.5 mm I think and thats only a liitle smaller than a wolfkatz 8mm specializer.You can keep the stock look too.
