how much boost

[gen2tegls]

how much boost is the stock boost on a 90-94 dsm and what can you run safley on stock internals? and what would be a good way to crank your boost up safley like a bigger intercooler etc..

Stock boost is around 11 psi. Poeple run over 30 psi on stock internals (90-92 "6 bolt" motors) but the car has to be very well modded to survive that. I wont go through the whole list again, since I've answered this so many times here. Search around, or go to the POSR site in my sig, and look on Chads page. He ran 31 psi on a completely stock motor and put down 497 whp. He has all of the mods one would need.

(90-92 "6 bolt" motors) what about the 93-94 whast the difference

since I've answered this so many times here" could u give me a link to where you might have posted on this topic before please

i watched your videos of ur gsx and that thing flys ur launches are soo nice and fucking fast

i think i might want to run around 20 psi and do these mods what do you think

-Intake Pipe and Filter
-Intercooler Piping
-Performance Clutch
-O2 Sensor Housing
-Fuel Pump
-Exhaust Manifold
-High Flow Downpipe....3 or 2.5 im not sure
-high flow muffler and resinator
-test pipe

and a boost controler and a boost gauge to regulate my psi what

got n e suggestions and what do u think else is necessary or isnt

By internal mods usually people mean pistons, rods, crank. These are the critical elements for surviving high boost.....or you may have parts looking like this



haha...detonation rules

he 90-92 motors a re 6 bolt motors, and the 93-99 motors are all 7 bolt. The 7 bolts came wiht smaller rods, so they generally cant take as much power on stock internals. I would be happy to do some searching and find you some links where this has all been posted, but thats your job You dont even have to search. I wrote up a nice mod path yesterday, so it should be on the first page of threads.

You will be able to run 20 psi on those mods, but you will need race gas, which also requires fuel control to compensate ofr the higher specific gravity of race fuel (or you will be running rich). To run this on pump gas, just add a good FMIC. A larger turbo will make more pwoer at the same 20 psi since a 14b is at its limits at 20 psi on pump. But it will work. Datalogging is almost required though, since you're pushing the limits of the setup. Better safe than sorry. There are some good threads in the last couple days about fuel control and datalogging, be sure to check those out. Hope it helps.

thanks man right now im tied up between a 93 gsr a 93 240sx fastback or a 90-92 talon,eclipse,laser i think im gonna go dsm i just wanna get a blunt idea of what they are capable of
