Thread: highest boost on a stock block with stock de headgasket

u13 stock block,gt2871r, 740cc inj , s4 cams ......15psi and on those crazy nights 18psi a/f 11.8 wot

yeah I plan on running 18psi as well but with a MP T60 turbo...

the sr20de motors are stout with a decent turbo setup and tuned 400whp should be a safe

I did at 29,5lbs 550whp on my old de... head stud lift...
Time ago on the VE at 17-8lbs 550 whp same prob...its not boost here.. but power.
Stock studs do no like to go more than 500whp. 600whp on aftermarket ones , after that use the 12mm ones ot gti-r
Now...at 1 bar 5xxx , I will post my last dyno in a cuple of weeks let say Im impress what this motors can take.. the only prob is the f%&%&%$ gear box.
Cheers.

We have plenty of stock DEs running 400+ whp with water-meth and 0 probs on the motor...a proper tune and setup will do that without probs so do not be scare.

thanks fellers.

I been boosting 19-20lbs a DE rr all day long for about 1 year and the engine holds up a lot im making 400whp the only problem is the 3rd ****ing gear, i have broke 3 trannys.

Get a alky injection asap.

yeah, 3rd gear sucks; i know a guy that have broken a couple 3rds with a allmotor setup.

jf-p11, wut turbo you have?

broken third with a P11 tranny?
I thought they were good for like 500whp or so...

Surely you're referring to a non 01+ P11 trans. I throw 400whp at mine daily and have ZERO issues.



This even further proves my point that it's not an 01+ P11 transmission. There's no way an all motor SR is breaking an 01+ P11 tranny. NOT possible, unless the transmission was jacked up before you even installed it.



99 P11 transmissions are weak compared to the 01+ P11 transmissions.
