@Brendon00000 I have no clue what you speak of, I personally own a 91 crx with a type r b18c turbo set up using a gt42r turbo, makes 504hp at 22lbs of boost and 422hp at 18lbs of boost, and I loose traction on the rev/go on first gear only. The only way to loose traction is if I had a club foot and slammed the gas pedal all the way instigating a burnout. Z06 corvettes, ls1 camaros and gsxr600 cant keep up with me. Instead of blabbing words of hate out when you have no clue of what you speak
a k swap in a crx is awesome a k swap supercharged is just rediculous, using more engine bay space for all the equipment when anything over 300whp in a crx has no traction, it is better for the engine and transmission just to have a k20a and some aggressive camshafts making 250whp, thats my plans for my crx
Perhaps the engine will, but not the tranny, as we found out. Second gear is toast. No need for more power, too much for autocross and street as is. Time attack or drags would be another story.
@RoccoR16V 105mm with 130mm crank pulley gives ~100,000RPM on the Rotrex C30-94 @ 8600 Engine RPM (redline for K20A). This is the max RPM for this Rotrex.
The internals are totally stock. The K20A (ITR) motor need not be touched, is rugged and reliable at the boost levels we run (~10PSI, 340WPH). We can't run as the drags as we can't pass tech due to battery location. Our main focus is autocross. But, to give you an idea of the power the Lbs/HP is greater then a Z1 corvette. You really can't use all the power on the street. For drag, I would go for the larger rotrex which would require building the engine but would get you above 500HP.
you are my inspiration for my crx, I will be doing a similar build, I have a 90 dx with a b20 vtec built but i am not not satisfied on to the k series! What internals have changed since the build? I read the article in honda tuning, but since all stock internals? Done a 1/4 mile yet? Im curious to know what it runs please let me know!!
Of, do your research first. And save yourself from embarassment.
