If I use GT35R which engine that I should use? 2.0l or up to 2.3l/2.4l ?? I make my car for dragrace 402m..many thanks..

 

Those things are pretty big, you could run just fine with either setup, you'd probably see a bigger increase with the stroked/bored motor, with a decrease in fuel economy, but now as I read your signature with those 1kcc injectors, I see that isn't a priority, so yeah, by all means go for the hybrid if you have the funds to buy it and maintain it. Good luck!

 

You're also not going to have as much reliablity or as high of RPM's running a stroker motor. I'd stick with the 2.0 and put the extra money into other mods to keep it running solid.

 

You means keep my engine 2.0l and buy GT35R ??
