Turboing My E36 325

[bavarianmotorsurgeon]

Can anyone give me some instruction as to what i would need to do to put a turbo on this engine? Ive found a few companies offering full bolt on kits that say no other modifications are needed for 5.5-6 psi but im a little sceptical, and have no idea who is the best to go through, or what modifications would be best to maximize my power and reliability of the engine.

how much $$$$ r u working with.......

1. Buy a turbocharger.
2. Install it.
3. Go fast.

if you need to ask how, you should send your car to AA to get it done for you.

Installing a turbocharger isn't quite as simple as "bolting it on". There is a fair amount of modification involved with any legit turbo kit - some of it is just moving stuff around so your new hardware can fit, little things like routing an oil return to your oil pan, and then tuning your car so it doesn't drive like crap. Like triggrhaapi said - if you don't really know what it entails, best to get someone to do at least part of the work for you.

I have enough money to do it i just dont wanna do it the wrong way. This web site has one for my engine for $2999.00

http://www.turbo-kits.com/325_turbo_kits.html

Im wondering if i shud swap in some low compression pistons or anything to make is safer for the engine, and if so who do i get them from. What other mods would also be good to make soe more power after its turboed? Oh and thanks to the guys who posted and were of absolutley NO HELP!

money doesnt mean you know what your doing...first off buying a turbo kit for your bmw from a place called turbo kits.com pshhhhh

and triggrhaapi is right...if you need to ask you really should just buy a kit from AA or send your car to AA.

Well if you have the money to do it right... here it goes... and I know this won't be a complete list this is just what I can think of off the top of my head.

You will want stronger O rings, headers, high flow cat+ larger cat back exhaust, True CAI, exhaust manifold meant for a turbo, turbo itself, oil pan, various lines, dending on your psi upgradded clutch, all new seals for engine, depending on psi new (think upgraded/low compression) cams may be needed, Wastegate, down pipe, blow off valve, intercooler, larger fuel injectors, larger Air Mass Meter, depending on psi stronger pistons,

The important thing to keep in mind is that you have to research each and every part, get detailed specs and have an extensive engineering knowledge to know how each small change in each parts spec affects everything else. For instance you can't slap just any old exhaust manifold on. Diameter, angles, material, all affect the flow of exhaust out from your engine. The turbo is going to be pushing a lot of air through. If everything does not work perfectly together you lose lots of power. It's a huge task to do yourself correctly. Good luck.

I know money doesnt mean i know what im doing, that why im asking. And to write off buying a turbo from a place just cuz it has a cheesy name seems a little dumb. And of course ill reseach it first thats why i came here to see if anyone knew. If you know as much about turboing a car as you seem to think you do, why dont you share the wealth instead of just tellin me to send my car to AA.

Anyone know sumone whos done this yet and how it turned out?

well for one that turbo kits.com website has no mention of any software for your car. and two if their gonna compensate for boost by using a rising rate fuel pressure regulator their just as bad as mech tech. your car will go lean eventually and your motor will be toast. now like i said previously if you know what your doing you wont need to ask. thats why i suggest you send your car to AA.

now just for the hell of it ill type out what your going to need

first how much boost do you want to run. then find a turbo sized for your application. depending on boost you may need to lower compression either by a headgasket or lower compression pistons. your also going to need an manifold to mount the turbo too. now depending on turbo your going to need a wastegate. your also going to need a downpipe. then you need to have intake piping made from the turbo to your intake manifold and an intercooler. and if you run more boost than your MAF can handle your gonna need to convert to a map sensor. turbo timer, boost controller, gauges to monitor your equipment. stronger clutch...your also gonna need to run oil lines etc for the turbo. and the most important thing of all is tuning. doesnt matter if you have a completely built motor that can handle 50 psi but if your running crap tuning it wont matter.

i dont know if i missed anything but i think i covered everything

edit: fyi im in the process of doing this to my car

[xsperf]

it is probably going to be troublesome, but i dont know.
however, here is an alteration

supercharger:

its cheaper
it gives u a tiny bit less
practically direct bolt on, no need for any of the turbo hassle

has anyone even told him what aa is

Trust me, if you've never either run a turbo car or turboed a car by yourself, you will hate doing it yourself. You will run into countless problems, and depending on your own level of mechanical prowess, you could be without bimmer for 6 months to a year. I have seen a man who turboed his 320i from scratch and he has yet to have it running well after over a year of installing it. I wasn't trying to be a dick, I am trying to let you know that it's hard to do.

[FruityOne]

very hard...
