Turbo Or Supercharger For M3

[BaLLZacK]

Ok guys this is what I want to do... I want have around 400hp at crank in E36 M3 (maybe 350rwhp)... Now I would love to stick to NA, but unfortunatly not cost effective at all looking at a minimum of 22K to drop a E39 M5 in. Turbo is cost effective as parts are around 3.5K vs. supercharger itself is around 6K. Could anyone please enlighten me on the differences of performance, reliabilty, and all the other good stuff or bad. I would love to hear your opinions and feedback, specially if you have went FI or turbo.

oh boy this is a huge question to ask, i'll just start off the answers, first read the faq, second, you could get 400hp from a turbo easily, third whatever you do don't get something cheap, i would only reccomend aa, well i'm tired that's enough for now, lol

someone else bring up the rear

There aren't many "cheap" rela turbos out there. AA is a good place to go though. A turbo is goign to be a bit more complex and they are not as reliable and have more thigns that can just go wrong, versus a all-inclusive supercharger unit. I hoping you know how a turbo and supercharger works because if you don't then I would recomend you not look into forced induction immediately.

A turbo has more potential, but isn't as reliable. You might want to look into reforcing internals and lowerign the compression, as your car has a comprssion ratio of like 12:1 or something high like that.

Also, have you considered other options such as lightening up the weigh of your saloon? Does your car have others modifications such as suspension and such in order to be able to handle the extra power and such you would mroe than likely be abusing?

Good Luck and keep asking questions.

Thanks shahab, read the faq and Prefect line, I dont want to go with something cheap.. I just want to figure out if its worth doing. dinan supercharger is 6K+ labor and AA turbo is 8700+ labor(according to AA I wont need to get forged internals, sounds like bs though)so maybe 10k+labor............... I could go euro engine for about 10K to 12k used I guess. What do you guys think is the best solution.
About lighten the car havent thought about that much.... I am looking to go with dinan stage 1 suspension and UUC stage 1 or 2 clutch and flywheel to handle extra power


Thanks for the responses

As for me personally i would go for N/A inspiration engine the EURO e36 m3 321HP if im not mistaken.... Its a beast.... and that will last you way much longer than turbo chargin it... way much less maintainence hassle.

EURO 3.2 M3 is the real M3

if i was ever to go FI i would buy it through AA no questions asked/.. personally i would b uy a S/C cheaper and i like them better for a bmw... seems more like na to me, even though its still FI. it doesnt give you as much HP but hell aa has put those S/c on bmws around 150000 miles on the engine. no reinforcement nothing... so that right there i like... not to mention the fact that you can put it on yourself if you are qualified enough in about 14 hours.... 100hp around gain defintaly should get it!!! i want one for either this 325 or my next bmw

swapping in a euro m3 is a hassle and not worth the amount of money you have to spend, a dinan supercharger isn't a bad deal, but i don't think you'll be getting 400hp, oh wait i just reread ur post, 400 to the crank sounds about right

If AA said you probably won't have to reinforce the internals then I would believe them. AA offers high quality work, parts, and integrity. The reason everyone loves them so much is their service. They aren't the average 9-5 parts store and I really can't say more than that without a example of a sale.

You defintely could consider the euro M swap but then you may not be satisfied witht he upgradability of the engine. People will always say how much you could put into the engine but considering it costs quite a bit more, I think it is a cheaper and more intelligent choice to go with forced induction. The respect for the people who can give a big ole middle finger to the compression ratio of a BMW engine couldn't be any greater. I've also got 2 words that say Turbo is a better option for you.

Boost Controller.

I started leaning toward the euro engine as well partially cause of the 6 speed tranny and partially cause superchargers leave you at about 355hp (34hp difference). Prefect line: If dont have to swap the internals then you are right the AA Turbo is going to be way more cost effective and an intelligent choice. Since I need not forged internals and I get them anyway would I be able to increase hp further? ?? and how does boost controller help so much....

also whats the maintennece issues with Turbos?

I wonder if I could find all the bolt ons for the euro engine or would I have to get custom ones. still researching...

i support you in going the forced induction road although i think turbos are a little risky, if the car is a daily driver go with a supercharger from aa. ive heard a lot of good things about aa and what they do. good luck with your decision.

[Team Perfect Line]

A boost controller allows one to manually change the amount of boost on the turbo. This makes the biggest difference because you can choose to boost 6 psi when you are drivign around say bring upt he boost to about 12 psi (and more) if you do decide to reinforce internals.

PM me for a euro spec M3 engine if you really want one. I can get one for ya if you want (approx. 3,500 euros (~4,550 USD) for the engine w/o shipping)

boost controllers help time the turbo properly, and from what ive heard, turbos die without a boost controller.

to most the big question is a matter of cost. turbos always cost more, but are better performers than superchargers,
