want go turbo

[BryceComstock]

aloha i have an 88 3.2 that im looking at goin turbo. i have turbo builds under my belt but not on a 911. how much boost can you put to a stock 3.2. and pros and cons on single or twin set up. also has anybody done a carburated turbo set up

[quattrorunner]

Carb turbo is horrible idea. It's been done but with what's available it's silly.
Lots of power can be had with 3.2 turbos. You have lots of good head start upgrades but it's not without some careful consideration.
Look up on search and you'll find lots of good info.

it seems to me that with trying to use only porsche componants your making it alot more dificult when theres so much on the market to build a turbo system,your using 25 to 30 year old technology when turbocharging has come along way. sorry i dont meen to ruffle any feathers but with alittle fabrication you can come up with a really clean set up. also ive built two vw aircooled engines. 2332cc turbo with carburation. dynoed at 320 and 382 so i know that you can turbo with carburation with success. just lookin outside the porsche box. reason for carburation is simply cost. 600 for a carb set up for boost meetering or 3k for aftermarket ijection or how much for a porsche injection getting it to work . once again not trying to get anyone mad but wana know pit falls of the engine more than can i turbo it thanks

[quattrorunner]

3.2 already has injection. All you need is turbo stuff. It's not hard. Not like a cis car. Like I said, your way ahead with the 3.2. But have it your way.

[BryceComstock]

So you don't have to modify the injection at all? Like I said just not familiar with porsche engines. That would make it easier. So what steps would I need to do injection wise for mild boost app

[quattrorunner]

Did you read some of the posts listed above? Look up turbo 3.2 in the search there is basically step by step threads.
For lower boost you might be fine with your injectors and a computer flash. It's common. The hard part is plumbing and oil to and from which sounds like your accustomed to. The exhaust part is the easiest part.

You do realize that planning to utilize a carburetor while at the same time calling out 25 to 30 year old technology is a bit of an oxymoron don't you? At any rate, your 3.2 already has computer controlled EFI so its a moot point. Read the links that Ronnie posted and you'll have all your questions answered.

[BryceComstock]

i get your point rodsrsr nice one. sorry just what im familier with. and quattrorunner thank you also. ihave read the threads very informative. with bug turbo apps. you lock the timing out at 32 dagrees and your good im asumming its different with this app. due to the injection?. and as far as i have read flashing the injection isnt a very good solution right? also coming from an alfa romeo background with the motronic injction i was always told you cant touch it . it doesnt handle change very well. also as far as detonation due to compression has anybody tried water meth injection to combat that. thank you again for your knowledge and paitence

[quattrorunner]

With your car, the 3.2 you have a management system that looks after the ignition as well as fueling. There are chips, or programs for the motronic that complement positive pressure. No need to lock the distributor. Look at protomotive chip as a search.
I use meth though I don't need it. I wanted to use it as a replacement to intercooling but decided its better to use intercooling and I just supplement with it.
There are other things obviously to look at like fuel pressure across the range. You'll learn it all.

[BryceComstock]

ok probably another nubie mistake but went to motronics websight and couldnt find any kind of chip or anything for 911s for that matter what am i missing

[spence88mph]

Protomotive will supply the chip and you can use their RR FPR, it's what I did, or something like the BEGI FPR. It's very easy plug and play, 360 - 400chp solution (7-10psi). I have an 88/89 too, you won't regret it.

[Tippy]

I have a Protomotive chip made for 55lb injectors if you need it. Good to over 1-bar of boost. PM me if you're interested. You'll need the matching Protomotive fuel pressure regulator to work.

[afterburn 549]

One would think by now there would be almost a "KIT" available as a base line with option features
Wayne...? What ya doing? LOL

[Tippy]

Bryce, I think the stick injectors are 24lb. You'd have to use 55lbs for it to run correct. Couldn't reply to PM on iPhone.

[Rodsrsr]

I prefer the MSD 6Btm unit with Boost retard over the chip, but they will both do the job. Just use a BEGI RRFPR in conjunction and you'll be fine. I'd go .5 bar boost. These are really the basics and are covered in more detail in the threads that are posted above. Good luck with your project!

[Tippy]

Yeah, the chip once you punch it will go to lower timing across the board (triggered WOT switch activates boost timing map) versus the 6BTM dropping degrees with boost.

msd sounds better sorry but getting lost with all the abreviations. wut is begi and rrfpr ? im asuming injection bits
