How high can I rev on my stock bottom end. The head would be completely built. Thanks

 

If it was me, personally, I would not rev it any higher then the engine makes power. Like if power drops at 7k, dont rev past there. If your getting up into the 7500rpm range and still making power, it would be wise to build the motor. It just depends. I mean people say not to rev the CRVTEC, yet I have a buddy who rev'd his to 8900rpm because he was making power up there with the cams and he never had a problem. This was the stock bottom end btw. I think that its up to you. Search around for peoples mini me setups and see what they are reving to.

Thanks alot for your imput blaze.

 

d15b2's a dx? thought it was an hf...

 

it's what came stock in my std. i think the std and dx were dpfi and the hx is mpfi, and then of course the si is th a6.

 

The DX is d15b2 and I'm pretty sure the HF is d15b6.

 

thats odd b/c when i bought my car it says it was an hf and the kid didnt mention anything about a dpfi to mpfi swap or any swap for that matter. doesnt matter now i guess since im not even rockin a d series anymore...

 

The HF was MPFI stock.

 

do not rev pass 7k
u will overrev the engine and blow it

remember the redline is the maximum speed the crank can rotate before loosing stability and causing damage

u rev pass that often and u will spun bearings and blow the **** up

 

ive blown d15's only revving them to about 6800. i hate d15's.
