I'm selling the Altezza I imported from Japan for a little cash and I'll be spending that on trying to turbo my F20B.

Now before everyone points out that the H22A is a better platform with lower compression, OBD1 etc, I'm keen to do the F20B because as far as I know it hasn't been done here in New Zealand. I've got the time and a little money. So why not...

Now the first step for me will be finding out as much as I can about the F20B. How much is interchangable with the H22A. From what I've read the F20B and the H22A heads are pretty much alike, apart from being OBD1/2.

Obviously one of the main issues is going to be OBD2. I'm pretty sure I can source an ODB1 ecu and adapter harness. Only problem is that my F20B's got a nasty Tiptronic mated to it. This leads me to my next question. Which tanny's will bolt up to the F20B block?

So anyway, I know H22A headers/intake manifold will bolt straight up to the block so thats a step in the right direction concerning a turbo manifold. What about head gasket. If its going to be turbo that compression ratio will need to come down wont it. I'm going to be running around 6 - 8 psi. Not much I know but will I need to bring that compression ratio down for that little boost? Will the H22A gasket work on the F20B if it has to come down?

Those are my main concerns. Thanks in advance...

 

did you see the f20b faq?

 

any f/h trans will bolt up to it
