im planning on buying a 27x3.5x6.25 intercooler. now im planning on running about 15-16lbs of boost on my swapped celica, will this be an efficient size, and will at fit with decent accomodations?

i have a 26x6x3 and thats worked fine . the idea here is to take off your bumper...and measure everything out so that you can get the biggest cooler you can fit in there.

as far as running 15-16psi. i had to add water injection to be able to safely do that on my car.

water injection on its way... your post was the only reason why i decided to get a boost controller to throw in as well

m gunna push a large IC idea more than anything. i could free boost 20+ psi with no signs of knock, and this "pressure drop" thing is pretty much un noticeable and effects lag minimally.

your right... a huge IC is a good benefit, but i just wish you had tvsv led's or had gone to the dyno with your setup. sometimes knock can be tricky to spot just based on feel.

Art, when i buy my huge IC ill let you know if i knock at high boost

what is size you mentioned before, that you believe you could fit in the gt-four bumper?
