I know everyone is going to argue on this but If you guys could just not argue in here cause Ill just delete it.

Ok, now my question, I have a 93 240sx with 137000 miles on it. I was thinking of going to around 7lbs boost at first then doing a complete rebuild at a later date and running 15lbs. Do you think the car can handle 7lbs seeing that right now it runs like a champ? If it could how long do you think itll last.

 

run the proper timing. and try it out. it's gonna blow anyway right? and you are planning on blowing it up and "rebuilding" it right? so what does it matter how long it lasts. go out with a bang if ur gonna do it.

timing. once again. timing. once again. fuel and timing. once again timing. have fun and good luck with the rebuild afterwards.

 

jonas, what are you using for timing and fuel control? im thinking of going for e-manage blue for fuel.....

 

depending on the size of the turbo it should be fine at 7 psi, u may pop a head gasket after time just becus it has high milage, but if u just do a t 25 or a t28 the motor and clutch will be fine at 7 pounds but like i said be expected to pop the head gasket

 

yeah, the head gaskets deff gonna go if it hasent already. youre due for a new one at 130K.

besides that, check your oil levels daily so you dont get a knock from oil starvation. and get it tuned professionally
