: hey guys, i just wated to put this out there to ask a few questions. I have an 88 528e and was thinking on supercharging it. i know... i know... why not get an M3, m5, 535i or a 325i and hop it up but i like the M20B27 engine and i like the spaciousness of the 5 series. besides, between it and a 2.5 there's basically no difference when you put all the go fast stuff on it other than a few extra cc's of displacement (in the super eta's case). ok here goes:

: - difficulty of motronic 1.1 to 1.3?
: - go with 2.5i intake or the BMP multi-throttle body intake for supercharging?
: - what type of supercharger? i'm leaning toward the schneller motoren tecknik supercharger kit but it seems pretty expensive.
: - would i be able to use supersprint headers from the 325i on my 528? just that i'm trying to see if i could get the headers to mount in the 5ser car

: well just a few questions to help clarify some concerns.

Rich,
I had a 325es, same engine as your. You might want to consider a minor modification instead. I found it very impressive. I installed a big bore throttle body, chip, K&N drop in filter (cone filter does not give you extra HP, but decrease the HP because of the exposure to hot air) and a 325i fuel requlator. With these mods, the car made a very noticeable different. At the end, I installed a complete exhaust system from a 325i (exhaust manifold, cat, and rear muffer). This really made me happy. You can find one from a wreck car easily. Although your car is 528e, your exhaust is a different set up. But, you can installed just the 325i exhaust manifold. I think you'll be impress. Good luck.
