AHHH ive tried everything... still not running right

[ExViTermini]

have you tried another dme yet? is throttle response good and normal with the crimped 100psi?

[MattM]

well, i put it all back making sure to mix up which injectors went to what cylinders.. and it made NO difference.

Again, when i plug the return line, i get about 100psi fuel pressure, and the engine runs great

brand new cam sensor.

Im currently giving the injectors a bath in some cleaner.

i messed up injectors cleaning them.. by dunking them in some cleaner. had to buy 6 ebay" calibrated" injectors. you're not supposed to dunk them i learned later.

Did you retime the car?
Did you remove the front trigger wheel for any reason?
You are using the CPS in the block I am guessing?


Unplug the cam sensor and see what the car does. And report back.

[MattM]

well, i finally got a new FPR.. it still runs like SHIT :curse:

I also bought a fuel pressure tester, and it shows 51psi(3.5 bar) so that seems to be right...

Its still not firing on all cylinders, im thinking it has to be the injectors now

holy mother of e30's..!

Yeah MattM, there's not much (if any) recording of what you're doing. Keep us posted on your work. I'm gonna be stocking you from here on out. Glad u got the m52 running well. Hope my wiring kamasutra thread was helpful ; |

[MattM]

yeah, the front diff is the weakest link... thats an interesting idea that he did to reinforce it.. might have to look into that.

one of the few pics i have of the pan.. still in construction phase..

Apparently spider gears in the front diff go first. Nowhere near S5x power though....

e30 back half of oil pan, e36 front half welded together. stock e30 ix engine mount arms, tranny and t case and front diff bolt up normally.

i went m52 for a few reasons

1- 1/4 the price
2- low km automatic donor car(less then 100k km)
3- sourced some s52 cams and m50 intake mani for next to nothing
4- finding even half decent s52's up here is hard

wow that's pretty crazy. any posted work on that oil pan???

i agree with 1-4. How would the IX t-case handle the extra power?

[red911turbo]

There should be just a small amount of vacuum. A large amount usually indicates a failed crankcase breather...which can basically cause internal vacuum leaks. Poor running and oil consumption are also an indication! Also weird honking or an air release style of noise.

We have a specific vacuum gauge to test it.

Glad you got this thing put together, any other future mods? Force induction or just bolt on's?

[samiam3356]

Awesome! glad you got it figured out. great work

[MattM]

Have someone keep the engine running for as long as possible while you slightly open the oil cap...Is there a large amount of vacuum trying to suck it back on to the valve cover?

yes, mad vacuum sucking it back on
