My 91' e30 M50nv Turbo Holset Build!

[eThirtyAaron]

Any new updates?

The incoming line of the EVAP canister comes from the underside of the throttle body.

Throttle body > valve with 2 prong? wiring connector > EVAP canister > return to tank

Your the freaking man!! Thank you!

Update!!

Sorry for the delay!


Work has been taking most of my time lately so I haven't had a chance to work on Betsy aka my e30.


Have about 90% of the megasquirt wiring done, it syncs to Tuner Studio via my laptop and registers gauges. Just need to throw on the intake manifold after some wiring tidy up and fab the intercooler pieces together.


Had the toughest time finding a way to route the relays together!

Heres a few photos just as a teaser (Dont mind the mess)



Coil packs all wired!



Only issue I'm running into is how to route these fuel lines, do I need to keep the EVAP canister? And does one end route to the non pressurized fuel line coming from the fuel tank and the other goes where?

Looks like its going to be a great build! also do you have a link to the clutch and flywheel you got?

It a standard F1 Racing Lightweight flywheel and 6 puck sprung clutch...they are all over ebay...

MAJOR DOWNSIDE TO LIGHTWEIGHT FLYWHEEL IS THAT IT IS NOT DRILLED FOR TDC PIN FOR TIMING THE ENGINE....I had to go by engine markings.....not a fan..

In retrospect would have timed engine first then swapped out flywheel..

Should use a cutring vs a MLS

I wanted quick and efficient proven build...The MLS although having its weakpoints..has been tried and proven in the past.

Are you talking about this cutring: http://www.cesmotorsport.com/documents/94.html

Any other options that's less than $500 for a copper spacer and cutring?

Same problem I ran into..MLS = cost effective and proven...I believe that the retorque procedure with the ARP studs as recommended should eliminate some of the issues people run into with MLS (I doubt most people pop off the valve cover to do the break in retorque...something I will be 100% doing)

sub'd. I've been thinking of boosting my NV

Do you have a 6 speed in the 135i or DCT?

How much does a trans cost you?

Sub'd.

The Car is a 2013 135is Fully loaded 6 speed manual..I have gone through 3 transmission with BMW covering 2 of them... The damn thing barely has 16,000 miles on it...what a shame...

Its been the 2nd gear syncrho every time that goes first..to the point that the gear becomes unusable and impossible to stay in..Hurrah for 1st-3rd power-shifts..

I have now blown up the trans yet again..this time with only the Upgraded pure turbos compressor upgrade and stock tune..probaly a net of 20whp over stock..very dissapointed here.

I guess I cant blame BMW completely though, I drive like a fucking T-Rex is chasing me..

(I figure hey, if I buy a sports car, I minus well drive it how it was meant to be...AKA redline shifts at WOT every time xP )

As for the cost the Stealership charged BMW a heft 8900 with trans install and labor..

OUCH..

Trans = around 3k with core from ZF
