I just recently bought my friends 93 prelude si. I've got alot of plans for this car, but I do have a few questions. First let me start with my desired setup. The car does have the h23, so that will be the first thing torn out. I will be doing the h22 full swap (engine, lsd trans, and ecu) , but before I swap, I will be rebuilding the h22. I know I need to resleeve. I was thinking about using the mahle gold series pistons, but I really don't know if I want to take the chance. I was looking at the rev hard stage II and III turbo kits. Are these kits good or should I just piece together the parts myself? My goal is 400-500 hp so I'm leaning towards piecing my own setup together. Im thinking gt35r turbo, tial wastegate, spearco fmic. What other parts do I need? turbo manifold would you suggest? I'd like to keep my ac if possible. Any help is greatly appreciated.

 

I would defenitly piece it together you will save alot more money that way.

 

You dont want a Rev hard kit. My first turbo build was with one and I wasn't very happy with it...... The damn exhaust manifold had holes in it when I got it. I had a GE manifold which caused the intercooler piping to not fit, etc, etc.

Piece everything together yourself

 

Part the turbo kit together, I would sleeve the block, I have heard ALOT of storys of the FRM (what ever its called) just failing above like 300 and the pistons that work with stock sleeves are hit or miss.

 

I think I will be piecing it together myself. Im trying to find a good "ram horn" manifold and looking up the prices for all other necessary parts. (boost controller, bov, hondata s300, oil lines, ect)

 

Also what would you guys prefer for the internals? Im thinking 9:1 comp ratio

 

Thats probably good 9:1 is what most people use on their setups where are you thinking about having it tuned at once you build it. It doesn't matter what kind of crazy **** you do to your engine, it woln't matter if it's not tuned.

 

I live in northwest indiana, about 45 minutes from Chicago and there is a place I've heard is very good called AMS. They're known for their crazy evo builds. I think I'm going to take it there.

 

I know of it thats a good tunning company I live in central PA and everyone here goes to a place in Bethel PA called Evens Tuning they have a really good rep and a really good website to prove it.
