what is the highest psi a DET or DE w/FMAX kit can run on stock internals?

 

Im not an expert but Ive heard that 7psi is stock and some run around 12psi on stock internals. Can anyone else confirm this?

 

Correct maybe 14psi the limitation is the small turbo NOT the internals. Bolt on a bigger turbo and the internals will handle 400-450hp.

The DE engine WILL never make that kind of power with OEM internals.

on the contrary i know of 2 sr20des that are pushing 400+ on stock internals. the stock boost for a BB (bluebird) det is 7psi.
the DE is very capable of handling a turbo with 12psi as long as the motor pistons bearings etc... are in good condition. (I did more research this weekend. ALOT actually!) the internet is a very good tool! especially webrings!

thanks for your replies!

 

Cool keep up updated as to the progress of the buildup/transfer.

 

Let me clarify....the DE engine can not run that boost level on stock internals at stock compression ratio as a daily driven car. You might be able to get away with it once in a while at the track etc. That high of a boost level on the DE engine will not last long.
