performance improvments for a M52...

What to do first in a 1000 dollar budget range.

I just want to hear what some of you would do with a 1000 bucks.

now from what i understand theres the M50 manifold if im correct?
or S52 cams??

i have really no idea so if someone can chime in on what they did with their M52 that would be GREAT.

thanks

Yeah there's the OBDI conversion which is $350-400
If you were to get an M50 manifold I'd get a chip to optimize for the new manifold as well. Try MarkD he quoted me somewhere around $450 IIRC for an ecu flash for the 530 (which is an M54 though)

I've heard that an M52B28 with an with OBDI conversion and a chip is good for ~220hp

Is that WHP? Cause if it's bhp that wouldn't be enough of an increase (192->220) ...software alone would almost do that. If it's WHP, that's huge.

I'm talking at the crank. An M52B28 with OBDI conversion, s52 cams, injectors, and a chip will bring the hp into e36 M3 range (~240hp@crank or ~209hp@wheels). A chip alone is not going to give the car a 30hp gain, usually 15-20hp gain max. An OBDI conversion plus a chip is probably good for around a 30hp gain (~225hp@crank or ~190hp@wheels).

There are many Forced Induction kits for the m52b28, I'm talking specifically about Superchargers. For the money you're going to throw for the manifold kit and the cams and tuning etc, for a bit more you can gain a lot more horsepower.

Or you might save a bit buy buying somebody's used kit.

Show me a supercharger kit for the M52B28 that costs $2k new...

VF kit - $4500 USD - 275hp
AA kit - $4400 USD - 310hp
Dinan kit - $6200 USD - 258hp <- wtf

So you're telling me the OBDI conversion essentially gives 10hp over the software alone?? That sucks...

Why does that suck? $400 for 10hp gain is decent.
All the conversion does is let your engine breathe better and it's only really noticeable past 4500rpm. It's like you're expecting to gain 30hp from putting something like a CAI on a car... some cars you might be able to (ie ford mustang svt lol) but that's not the case with BMW's, typical gains are 10-15hp from what I've read.

You can typically find used sets of s52 cams for between $300-$400. The will run fine on the stock tune, but one again to get the most out of the mod you'll need bigger injectors and a tune.
The best thing to do would be to save up a bit longer and just buy a kit

Search the E36 section here and on BF.C. This topic has been discussed to great lengths many times before and there's plenty of good info out there.

If you haven't gotten an LSD yet, do that first. Then M50 manifold.
