A GT42R will not work as well on a 2.3 or 2.4 litre. Yes, you can still make good power on a stroker with the 42r, but it will not be the best setup for drag racing. To build a true drag car with that large of a turbo you need to ring the bitch out to high rpms(10,000 rpms), which you know a stroker motor can't do.

Shep actually shifts his car at 10K and crosses the line around 11K when he makes his high 7 to low 8 second passes.

Stroker motors are safely being rung out to 8500. Some people are even going to 9K with the 2.3 or 2.4, but revving that high is just asking for failure.

Obviously the nitrous helps tremendously.

Nice build man and I wish you luck in your goals.


Bingo. I dont plan on using nitrous but I do have a direct port system waiting if needed. I intend on shifting around 10-10,200 to keep the turbo spooled. He is right about the strokers, you cant get enough rpm to keep a 42r in boost. I went with the 70mm though to keep from having to use nitrous.
