38 posts in this topic

Been underway for a little bit now just have some time to post some pictures. This is a car for Andy...super m42 swap

76 02..

BIG wilwood front brakes

VW rear discs

m42 swap/e30 5 speed

super 60 turbo

42lb injectors

stock motronic efi with a tuned chip

low boost around 7psi

The intake and valve cover will be powder coated red and charge pipes will be black. Waiting for parts to come back from the powder coater before I can put the rest together fire it up and get to tuning

Stock compression? I have the same turbo in my garage right now, and I'm interested to see the results.

DO YOU THINK YOU WILL HAVE A PROBLEM WITH THE TURBOCHARGER

BANGING ON THE SIDE OF THE FENDER ?

yes stock compression

There is space between the turbo and the fender and it will have poly motor mounts. If it hits I will make a little space with a slight hammer massage.

Tuning the stock motonic with tunerRT and an ostrich2. It will have a set of 42lb injectors and then a burned chip when it's all said and done.

Sounds like a good setup. You have a baseline tune to start with or are you going from scratch? I would think the AFM would be maxed out pretty quickly with that setup? any way around that?

There is a guy in canada that I am working with that has a similar setup. He is running around 12-15psi in an e36 with a m42 and a blow through afm.

I am starting from scratch. Tune the idle with a wideband to set the new injectors....adjust all the maps to work with the new injectors. Then tune the WOT table under boost and transfer what I need there over to the PT tables. As well as pull a little timing in the areas where under boost/higher load.

There is a oil connection at the back of the head. m12x1.25 to AN3 fitting did the trick. need a manifold?

This project got put on hold as I was working on my own e28 (needed for the new baby). Anyway..its "done" for the most part now so I am back to the turbo m42 car again.

I was having trouble with the tune a bit and a hot start issue so I changed the way the AFM is metering the air. Before I had it as a blow through. I changed around the charge piping and now it is setup as a draw through and using a bosch by pass valve instead of a blow off valve.

Going to do some driving in the AM when it is a bit cooler outside. 91 out right now is not very fun....

A few pictures.

Tune is getting closer...got into boost a handful of times and at only 6psi it is FUN. I am going to push it closer to 10psi when all said and done.

Still having a hot start issue...it happens when the car is fully warm. Shut the car off and it will not restart right away. I swapped in the stock injectors and tune today and it ran fine and restarted when hot. I am thinking the injectors might be leaking a bit. Sending them off tomorrow to be cleaned, balanced, etc.

Hot start issue is fixed!! The problem was with the tune it self and dumping too much fuel in when starting. All is well now.

It is good fun.
