I am recently finishing my e21 with a 3 liter M54b30 swap.
Here is some picrure of the building:

The brakes look pretty sweet too.

oh please do a write up on the brakes you have used, im running porsche split rims and would love to be able to ditch the adaptors and just run porshe parts up front

really like your air intake idea, looks very factory and im sure will have good airflow there

did you use original engine management? how did you mod it for e21?

[nige21]

Great conversion! The car will be an absolute rocket with that motor... I would think there is a fair bit more power left in the motor above what they are from factory too.

What radiator have you used there? looks very neat.

well done

very nice! i was going to ask which rad that is as well - what I ended up doing was finding an rally spec mk2 escort one that fits in the gap perfect, yours looks like it is from something else?

best first post ive seen on this website so far lol.

love the brakes, did you do the work yourself?

[Peter V.]

Very nice build you did.

Glad you have chosen for the right brake setup with that kind of power.

awsome build cant wait to see finished result keep up the good work

[himizoli]

The radiator comes from E30 325. The front wall has to a bit modify to fit it.
I have to remove the factory visco fan and install a Spal fan . Now I have 10mm between the fan and the water pump.

The factory enginer ECU is removed. I use a programable standalone ECU with Vanos controller.
All work is made myself with some friend help

Some picture of the custom exhaust system (2x50mm tube)








The tube bending was pretty hard work

[nas80]

the e30 rad eh? i think you must be using the 1.8i s? oh man your m5x conversion beats the shit out of my effort thats for sure!

how long has this taken you so far? have you got any more pictures or another build thread somewhere?!

can i have your autograph lol

[himizoli]

To reach this stage took me 4 years. The hardest part was finding the proper standalone ECU.
Here a video of the first start up.

your car looks awesome. one thing i noticed that i wanted to mention was the exhaust wrap. that stuff is great for keeping temps down but it can really kill your exhaust with rust. had a buddy who used it and after about a year he couldnt figure out why his car was running rough, sure as shit, there was a rust spot in his manifold that was about the size of a dime

We have made an aluminium powercoat for the tubes and the muffles. The header is stainless steel.
I am planning to make a complete stainless exhaust system if it will passing the dynotest.
