m30 turbo redo!

[kylelauffer]

I had a 91 BMW 325IS. unfortunately I was not satisfied with the power.
In a means to enhance the power I did a M30B35 swap. While running the car a cotter key fell into the intake manifold and surprisingly enough did not hit the valve. I decided to resurface everything and turbo it.
The First Set up:
745I turbo manifold machine for T3 flange
Garrett GT35R 1.06 exhaust housing
23x7 inter cooler
Miller turbo package 36lb injectors 4in MAF War chip.
Dyno:
256 HP
365TQ

Eventually I got an exhaust leak with the 745i turbo manifold...
So I decided to change a couple things.

New parts:
Good&tite turbo manifold
Head studs and thicker head gasket
non inter cooled
water injection




38mm Wastegate.





Bottom mounted 35r with 745i turbo manifold









Good&tite Turbo manifold (very nice by the way! highly recommended!)

Wait, you made 260hp with a gt35r?

You may want to rethink your turbo choice unless you are going for at least twice that.

Small inter cooler is why my hp was lacking.

I am going with no inter cooler now for no restriction.

First I like your car.
if you are haveing problems with a innercooler call todd at tdc I like the air/water innercooler
keep us informed I will follow the project i might be in the market for the miller upgrade.

[kylelauffer]

thank you!

yes i have looked in to that before. i already bought the water injection kit. i bought the best one they had. its coolingmist.com i can run 12 psi with it.

but ya that is a good option. how much are you making?

I would keep the intercooler and move the TB to other side of the intake manifold to make the piping easier to route.

I'd don't know much about turbo's, but I think deleting your fmic isn't such a great idea
Intercooler=colder air
colder air=denser concentration of oxygen
more oxygen=more hp etc etc...
Have you thought of upgrading to a bigger fmic?

I ran 319whp 335wtq no inner cooler @10
I was useing for DD but if you are going for power
Good & Tight is right by moveing the tb to the other side makes it easy for 2.5-3" pipe and bigger innercooler you should be happer with that any way.
have you used water injection?

good to see you still on board I saw the E36 vearygood.

I do like this.

[kylelauffer]

im not looking for anything too crazy. i already bought everything but have not wired in the water injection. just kinda shooting for 350. it was pretty fast before. i cant imagine with the equal hp

[kylelauffer]
