I am wondering what are the best mods to run mid 14's, and get power up to about 8900 rpm's with a jdm gsr (sir-g) engine? Could I do it with stock itr cams, valve train, and exhaust? What do you guys think is my best route? Also is it very difficult to tune this setup with a hondata tuning device?

why exactly do u want to rev up to 8900 rpms? with itr cams you would fall out of your power band so what would be the point?

 

i was able to run low 14s with a stock gsr swap in a 93 hatch with slicks. have you run your car yet? Id say work with what you have and then go upgrading parts later. you might be suprised to see it will run what you want already.

 

itr cams and valvetrain is always a good street upgrade.there is no need to rev that high though,8400 would be good; after that itr cams would fall on its face...
you should be running 14's now, what kind of car is the engine on?

 

94 rs is my current car. I thought itr's redline at 8900 rpm's. or is that just the jdm b18c5? Even if I am out of my powerband at 8400 rpm reving to 8900 would give me that much more power into the next gear would it not, correct me if I am wrong. Once I do the swap I should be running mid 15's stock.

 

If you want to rev that high do alot of work on the head. P&P, Different cams, springs, retainers. Once you do that you will need to do some tuning to make up for the mid range power you lost. You could also mill the head a little to raise compression.

Nope. peak horsepower and torque is achieved b4 redline and redline is where it would be the most effective point to shift at. if you are upgrading the head then get aggressive cams(assuming this is na) to make power higher up in the rpm that will met your power bands efficiency.
