just picked up a 96 240 with an s15 sr20 swap, basically stock minus the front mount, tubular manifold, bov, etc.

what's the max boost i can run with the stock BB t28, and how much power can it safely hold?

also, what's the best oil to run in these motors, im use to running 20w50 with lucas in my mustangs..

any imput would be great, thanks...

 

stock wg pressure. get a front mount and you can bump the psi. Anything over 14psi is a waste.

 

^ i think he means its stocks except for FMIC, BOV, and manifold. You can run 18 psi on 93 but you should go to XAT to get it ROM tuned properly.

 

oil weights don't really matter in florida..just heavier weights means it last longer..i put 5w20 in mine and changed it every 2000 miles

 

I run 10w30. Keep it <14 psi untill you get a rom tune.
pics!

 

will do, thanks for the imput guys..


if i mess with the fuel on the safc and run it at about 12-13psi before a rom tune it should be fine right!?

 

I run 14lbs when I run it hard without a rom tune or a SAFC on a T25 and have had absolutly no problems. But for daily driving I never exceed 10lbs. Its been fine for 2 years.

 

Awesome, that's the info I needed to hear, thanks man..

 

be sure to know how to tune hte safc though

 

im good with safc's, ive had a few boosted cars before, but never a nissan, just wanted to get the basics..
