Time for the e30 BMW "GMW 353i" to get tuned.

I have been driving around with this car for quite sometime, and i have been spraying a 100 shot for awhile with a "mail order tune"

The setup:
1990 e30 BMW 325i
5.3l Vortec
LS6 Z06 cam
Stock ls1/ls2 exhaust manifolds w/ 2.5" straight pipe
LS1 intake ( for clerance )
Stock 5.3 computer, harness, the whole works
tr6 plugs
100-150 wet shot ( tuning for 150 shot )
stock 28lb injectors
adjustable fuel pressure regualtor
corvette fuel filter/regualator
No 02's....
Stock th400 with stock converter
4.10's
stock fuel pump

Looking to tune the car with a 150 shot to see if it will handle it without going lean. I will be actually be spraying a 100 shot until i get different gearing, instead of the stock 4.10's

Not looking to put awhole lot down cause of the mods done to the car, but with a 150 shot i think it might put 400rwhp if im lucky.

COOL! I'm building a very similar 5.3 with Vette cam for my Z-32, (thinking about switching over to an E36).

You mention LS1/LS2 exhaust manifolds. Which ones are you using?

i believe for the passengers side i ended up useing the camaro one, and the drivers side i ended up using the LS2 GTO manifold.

i also have a e36 im building up with the 5.3, and a t70 turbo

Should be fun too

Well, i never was able to get the car tuned cause of something acting wierd with my cam position sensor so i couldnt get tuned for the 150 shot or anything at all.

So sense we drove an hour to get to the dyno, i said hell with it while we are here im going to see what my car currently puts down N/A, and then with the 100 shot.

Car is completly untuned, with the mods in my first post ( not sure how much power loss from th400??)
but here are the lowsy numbers...

N/A: 256.51rwhp / 267.79Tq

100 shot: 372.44rwhp / 431.95Tq

Nice numbers for an untuned 5.3, very nice...

I started looking around for an E36 yesterday, spent most of the day just trolling car lots. Need to get my Z32 up for sale...

Looking forward to more updates...
