hey .. i have a homemade turbo , i have been running 5-6 psi for about 4 mouths now.. i want to go to 8 or more.. it is a sohc d15b7 block with 91 crx intake mainifold and wiring.. stock injectors and i added a frp and a fmu... also have 112 octane in it right now.. i just wanted to know if it would take the 3 more psi without a problem or what.. please help me guys. I dont want to me walking home.. and i got some fools o take out tonight ... !!!!!!

 

i personally wouldn't do it. I remember running the greddy turbo on my sohc and 6psi safe without doing anything to the fuel setup, but anymore and it would ping. You need to get at least some 310's and a fuel pump. Higher octane isn't gonna help if you can't get enough fuel in there.

 

ok.. so what injecotors do i need to run when runing a chiped pm6 ecu.. i have a fpr and a fmu ... and a crane stage 2 turbo cam... .. im on 5-6 psi now.. i want to run like 8-10 .. strip.. 5 on the street.. 10 on street if needed at the illegals

 

If memory serves me right, those rods are toothpicks.

 

What kind of manifold did you use on your 1.5

 

word up! little bit of detonation = boom!!

 

damn... sohc motors are pretty strong. I was wondering is retarding the timing something you do manually or is it in the tuning and ECU?

 

I wouldn't do it via an FMU, but with a set of 440/450's and an AFC, I ran 12psi on a stock 85k mile D16 which still runs 100% strong today, abeit not boosted anymore. Fuel and timing is the name of the game here, but it can be done.

 

D15 is poo. you're already on the ragged edge.

My d16z ran 10 PSI all day, no problems, all stock too

then i went for a B18C. but thats another story.

 

you might wanna ditch that FMU, get a intank fuel pump (eg. walbro, etc. etc.), bigger injectors 330's/440's work well. Standalone/piggy back management couldn't hurt either.

 

That post truly helped him out. Thanks!

 

i run my z6 @ 13-14lbs, 440 inj and vafc....and yes it still has them little "toothpick" rods and yes it makes more power htan anyone seems to belive..
