ok does anyone know how much horsepower the stock block and heads of a 1st gen dohc zc motor can hold?....i have a 13b turbo to put on it need to know if i need to do any internal work on it before i put it on im not gonna run a big psi maybe somewere between 6-10 psi unless the motor can handle more

 

i pushed 160 to the wheels boosting 5-6psi on a t-25. stock internals just upgraded cams. purty fun but it gets expesive trust.

 

I think 6-10psi is safe for stock internals. Tuning is the key..

 

Easily 6[66] PSI. It isn't problem to boost an engine to any amount of power as long as you're willing to grenade it.

And since I see nothing about properly tuning A/F ratios, chipping or otherwise, have fun.

Might I recommend our sister site, Honda-Turbo.com ? It's a great place.
