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.

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

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

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.

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
Black Ti? Was it you that I asked what you had in that thing on Eglington a few days ago?

yup

hopefully see your S4 again... now i definitly know what you got under there lol


$400 is really good when you get 10hp.

think about it, 40 bucks for a horse is a great ratio. not many performance improvements bring that kind of return.

boost is good, but dont want to get to crazy.

plus. if im going to spend 6000+ on a turbo kit. might as well save another 10000 and get a Z06 .

Most definitly going to save another grand or 2 and go with the package from euro sport that dinan M5 sent the link for.

that's my opinion (after you've done the rear end + intake)

turbo kits aren't 6K. you can have one installed for about 4200$-4500$. Since you'll easily gain at least 100 horse, by your own logic, its worth it.

I have software, underdrive pulleys, and other stupid shit on my m52. Almost completly useless. Get a diff, boost, mabye an m50 + cams if you really wanna throw money at it. Otherwise, ****it.

but with boost would i need new pistons, connecting roads, mabe a ported head??

as it turns out i do have LSD,

i dont think it would be a smart idea with crazy amount of horse going into such a short car like the Ti.

see i guess it will only be 4500, but what about an install on a ti. im probably going to need a lot of custom brackets. not only that id need some ultra performance tires etc.

i think boost should be done in a more proper car like an 328IS or a 4 door. and i also wouldnt want to sacrifice on the realiability aspect on a car that has over 200,000km

i was mainly asking the question on more common mods like the OBDI conversion.

another thing is i know i wouldnt need the performance tires or any of that crap. but it should be done, and i dont want to get that deep yet.

technically still adjusting from a car that has a 1.8L 8 valve which probably has like 80 WHP.
so the M52 is still a quick car with it being stock. add another 100 on that... cant imagine driving that in city traffic lol

$400 for 10hp Good? Hell it takes 8hp for someone to even physically notice an increase. Get a dyno tune for that kind of money.. No way would an OBDI conversion be a wise investment....

For $1000 to get decent increases for PERFORMANCE..

#1. Clutch fan delete (almost free)
#2. 3:91 LSD ($300)
#3. Exhaust ($500)
#4. CAI ($200)

And there you have it.. You'll make your engine breathe better IN and OUT and free up some lost HP by having to spin the clutch fan... the 3:91 will snap up the Revs nice and fast.. then you'll be wanting a Shifter to slam the gears a little better.. If you ever need to replace your clutch then toss in a Light Weight Flywheel..

With the next $1000. Invest in suspension, a Tune and shifter and you'll be enjoying life.

Forget doing the ODB1/M50 conversion if that's all what you're interested in. You will lose a LOT of bottom end torque and maybe gain a small amount of HP up top.

The biggest difference you will notice is if you put S52 cams in your motor. Basically the S52 is almost identical to the M52 except its is a bored and stroked version (its not a real M motor). The head is identical except for the cams and springs. These usually go for around 350-400.

Also in regards to software, do your software at the end of all your intended modifications as it will need to be tuned for the mods you have done.

There's a sale on Conforti software going on right now on BF.c by turner motorsports. The basic shark injector (no mods) is now 299 USD.

The 3.38 LSD is also a great option.
