I've been researching for ages now about doing a turbo conversion on my 2.2.
I have a S-truck, but the motors are quite similar.

I'm getting a 1991 Toyota built CT26 'Twin Entry' turbocharger.
I will be either building a log manifold or something similar, depending on how much space I have around the steering shaft.
I have the Denso built blow off valve on my desk.
I may be getting the MR2's intercooler, not sure, will have to see what sort of shape it is in.
I've been looking at a sandwich plate for the oil filter, to supply the turbo. However I will have to determine if it is necessary or not. Might be other places to source oil.
I am not sure what size oil restrictor to use. I know the MR2s have low oil pressure at idle.

HP Tuners is not available to me, been trying to find a suitable piggyback, the more I research MegaSquirt the more I get turned off from it. Looking at the AEM F/IC because I haven't read much good with the Greddy E-Manage. However I cannot verify anybody using one on an S10, or cavy. I had originally been planning on using stock injectors and a SDS EIC controller with two extra injectors installed in the intake piping. However I do not really want to do this setup, but I've seen people online use it and it works.

Do you have to do something with the PCV system?
I will be looking into a top feed conversion and larger injectors.

My motor will be getting a rebuild. The crank and two rods are toast right now, I have a crank and stuff.
I'm going to see about getting forged pistons, maybe eagle rods, will have stainless valves, possibly roller rockers, depends on how much money I get back from taxes and how soon I get hired someplace. I have a friend who owns a cylinder head shop and I'm learning how to fix up my head. It'll have a bit of work done to it.

What am I missing, what areas are of concern with the 2.2? I may eventually build an intake manifold.

I realized this is the wrong forum, I @!#$ing hate this laptop.
