T4 frustration, Got me thinking conversion Options

[jeffdon]

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?

A) Don't waste your money on Biral or Aluminum cylinders. A 2056 should run plenty cool without the expense.

B) I can do carb rebuilds, but I do a bunch to them and check everything, not just install gasket kits. So it's pricey and you may want to check around.

C) Stock valves are fine for a 2056.

D) I feel the Webcam 494 is a little aggressive for a street car. Sure it'll make more power, but 28 degrees of overlap will make tuning more difficult. Bigger HP numbers are usually all gained at the top end, and at the expense of low RPM performance. Smaller cams and stock valves increase port velocity at lower RPM and increase low end torque and drivability. I would pull back to a Webcam 86. It looks 'weaker' on paper and you'll probably notice a drop off in 4000+ rpm performance, but the increase in low end would make me happy if it were my car.

Trying to avoid splitting the case. That said...if I do, anything else "while I'm in there?"
