Hey guy , i'm planing to add boost on my ZC , it was already in great shape running 14.9 at 92mph it was good but never enough , i know that psi means nothing , it's all about tuning but how far you can push a Zc Dohc for daily drive during the week and Trac for week end , all suggestions and opinions will be appreciate , I want a nice setup , need yopur help!!

 

I've done up to 20psi Stock. But that was for about 1 second with a shitty boost controller!!!

I ran 8.5psi for about 1.5yrs and then up to 11-12psi for another few months before I tore her down to withstand 22.5psi daily.

 

USDM D16's can take around 200whp before they become unsafe, but ZC's usually have thicker rods. In this case, I wouldn't go more than 225, or 12-14psi depending on the turbo.

 

wow alot of crap in that post.


What zc's scholar?

 

haha "scholar"

i think the brown top zc ones are thicker
semnos had pics once, 86-87 i believe

 

PM7 Rods (ZC) and USDM D16 rods are the same. No difference.

PG7 (87-89 teg) are thicker, but made of a crappier material.

Oh and the 200hp Unsafe mark as been proven wrong TIME AND TIME again. 230-250 stock has been seen in DD applications.

 

200 to be safe. 220whp with a good tune..i wouldn't hit more than that with a stock internalled motor.
