I have been plagued by a series of issues over the last few years with getting my T4 running well. Some of it due to my screw ups, some just bad luck.

I keep thinking how nice it would be to have an engine that just starts and runs, and has more power. Subie maybe. But I sure like the couple of Honda V6 conversions I have seen.

Anyone here that has done a conversion and regretted it?

Yeah, I have started to calm down about it a bit. At one point, I had that thing running really well. No reason it cannot do so again.

My only time frame is that I want the car on the road for Rennsport next year. That gives me a lot of time, and I can rebuild as time and coin become available.

My bottom end should be good. My last fail was my own fault, freezing the cylinders due to water getting into the carbs. At the time, I had no money, and rebuilt using donated P and C's, mixing and matching and having to use spacers under two of the cylinders.

I am runnning webcam 494, stock crank and rods, 96mm pistons. I am leaning towards:

A) Brand new 96mm P and Cs. Go Biral this time on the jugs. Any advantage to fancier (more $$) pistons?

B) while the car is on stands, send out the 40 IDFs for a pro rebuild. Who here does them? I cannot recall. Or should I consider going to mega/micro squirt?

C) Heads - Any advantage to going to larger valves on a 2056? Do not think it will be in the budget too go with brand new castings.

D) what else would ya'll consider?
