It would cope with anything you threw at it.

If I were to do this, the car will be tunring into an all out drag car so do you think your statement would still apply?

One option might be to buy a 2JZ 'bitsa' motor, fit it with 2JZGTE pistons and then your 1JZ head and plastic turbos (making a 1.5JZ). Altenatively you could decompress it using a thicker head gasket. I think Manny has built a 1.5JZ - why don't you chat to him.

So aside from the compression that the different pistons make are they comparable in strenght ie. if you used a thicker head gasket to decompress it would the NA-T engine be as strong as a GTE?

By the way, there is nothing magical about the 1JZ head - it just allows you to keep your 1JZ turbos. I couldn't help but flow test both heads and do some porting to bring the 1JZ head up to 2JZ spec.

The only reason I would be using a 1jz head is if my bottom end is stuffed and the head is still good and I may have found a cheap 2jz-ge short block. So you have actually flow tested the 2 heads? I think many people would be very interested in knowing the results

Quote:

Conversely you could decompress your 2JZ using a 2 or 3mm head gasket (readily available from the States) and fit a real turbo on a custom manifold. This is clearly a more expensive option.

As the car would be an all out drag car, this is the option that I would be doing. I don't think the CT12a's would be ANYWHERE near enough for a drag car Smile
