should I build my motor or buy a k20

 

going to need alot more info on what you plan to do with the car for anyone to take you remotely serious.

 

k20

 

I would like the motor to push 500whp and can a d17 block hold up to a turbocharger

 

Do some research or kill yourself

 

In my honest opinion, buy a K20, there are several stock bottom end K20/24 based cars out there pushing the limits and making the power you desire. For what you would spend on building your D17, and being there just isn't a big market for your D series that you're wanting to build off of, you'd be cheaper and happier in the long run with a K series based engine, it would require a good bit of fab work and one off parts to make that kinda power, and I really doubt at the end of the day, you'd be able to make pull after pull and not fight issues. Im no expert, but I figured id give you a honest answer and why I give the answer vs some of these wizard dick key pad ninjas with there garbage.

 

Not sure if OP is trolling or just a total newb. Regardless of what your doing, k-series is the only smart way to go about this, or get a different car. D17 is useless for anything other then commuting.

 

idk my d17 pulls ive raced quit a few ppl with it on the streets and it performs well enough to beat some guys that think there car is fast to lol but yea Ive looked around and theres hardly any aftermarket performance parts for d17.

 

you're racing equally slow cars then

 

I know but u didn't have to remind me lol
