Just have a couple of question about force induction (turbo) so I have some basic idea about setting a system up for my 1991 318is.

I have seen several photos of other set up. One question is. Is the MAF gets eliminated? If so how is the air flow gets metered?

Do I need to change the ECU for better management?

The stock throttle body. Will it work with turbo application?

For the most part I can manufacture the exhaust manifold to meet my need to put together a system.

Which turbo is best to run with? T3 or T4.

What size tubing is best for the application?

How about EVO turbo?

There are several pictures of other members turbo. Most of them show the tubing being hooked up directly to the throttle body without the MAF in play or I did not see it in the photo. Thank you for any inputs. If I missed any other critical parts I need to consider please share them.

I consider myself “old school” meaning big piston, high lift cam and big carbs for power. Now this days “turbo” is a house hold name now so I thought I would give it a shoot in putting together one.

Has anyone used the intake manifold from”666fabrication”? Does it come with it’s throttle body?

I would suggest picking up Maximum Boost by corky bell


Read that at least 2 times and then use the search function on this forum till you get stumped.

Its a excellent read and will put you on the right path.


Good luck

+1. Based on what you've said it seems that you should do some real reading outside the forum to get a better grasp of the setup. It's not easy to just piece together a turbo kit, and no, the stock ecu/tuning won't work with the turbo.

I thought this sounded familiar. Just read this on e30tech...
