cheap 3.2 turbo conversion

[WydRyd]

dickster, yes, I'm still running the J-Pipe setup with Stage 3. I haven't noticed any significant increase in lag to be honest (then again, I haven't really taken her into boost at all), but it probably will limit my boost response and top end power somewhat.

I think the GT2 CAMs and slight capacity increase offsets the decrease in C/R, because it "feels" exactly the same as before under pre-boost condition. Exactly what Todd told me before undertaking this upgrade

David, my opinion is biased because I love turbo's and the capability exists to extract serious HP out of a forced induction setup. You can only go so far with natural aspiration It all comes down to personal preference I guess. Try to get yourself in a turbo'd 3.2 and see how you like it

Thanks Wyd

I've owned both a 3.6 77s lightweight car, and a 84 911 turbo, which was electromotive twin plugged, cams, big turbo, etc.

The turbo probably had somewhere around 325-350hp, but it had a botched G-50 install in it that slipped. It was still quick, but the clutch slipped and the tach went to redline too easily.

The 77s with the un-junked motor (headers) was probably a tight 275hp.

Both of these cars were overkill, and there is a reason I don't have them anymore; breakdowns, oddness that no one could solve (I dropped the engine three times and tried two different clutch kits, and the hydraulics leaked fluid on the G50 clutch)

What I'm getting at is if there is a simpler way to squeeze some more power out of a relatively mild 3.2, using some protomotive pieces, I'd gladly do it. I don't think I will spring 6K for a turbo update, but if I can mix in some ingenuity, I'd like to drop 3-4K. I'll keep an eye on racerman's progress and see what I can learn.

merv,

thanks, thats good to know. the cheapest kit with the J pipe sounds like a good place to start.

Amen to that Brother...............

Anymore info on this Proto on the side kit? I have never heard of it.

[WydRyd]

Go to www.protomotive.com and have a look at their Product Descriptions for the Carrera, 964 and 993's.

[porscheboy16]

I can't find anything for an "on the side" kit. BTW I have an '84 Coupe. Any HP estimates?

[WydRyd]

~ 360HP @ 0.5bar 9.5:1 C/R , or ~400HP @ 0.7bar 9.5:1 C/R, 485HP @ 0.85bar 8.8:1 C/R, 550HP @ 1.25bar 7.0:1 C/R.

Anything over 0.5bar is Intercooled.

If you want more specific info, e-mail Todd (knighton@protomotive.com)

[david.avery]

You guys have more money invested than I want to invest... I may only speak for myself, but the idea of a DIY (with certain sourced parts) for what Racerman is paying out is more what I'm interested in.

I would love the protomotive stuff, but I'm not going to dump 10K into my car worth 15K tops

[porscheboy16]

WydRyd,

Those are Stage 1, 1 U/g. 2. etc/

One guy spoke of an ontheside kit for a lower cost. I think I heard Juan speak about it a long time ago, maybe he could input.

In my early conversations with Todd at Protomotive, he mentioned an "off the side" fabrication that was cheaper than the full stage I. Basically, you take digital pictures of your exhaust system and he figures out how he can accomodate a turbocharger by modifying the parts you have and suggesting replacements where needed. In my case SSI headers would have been modified and I would have needed a new muffler. I went with the Stage I because I really like the design and fabrication of the Protomotive system as a whole. I think you do get what you pay for here The Stage I is expensive, but made entirely of stainless and really well fabricated. Should outlast the car. IMHO if you are really serious about turbocharging, the Stage 1 is a pretty good deal for what you get.

[raceman]

lf you want to do this fast and cheap then buy a used 930 exhaust,used 930 turbo, wastegate and muffler.Buy the Promotive chip and FPR,some stainless or aluminum mandrel bends from JC Whitney,and various widgets and tubes and you`re there.lt can be done for $2500.00 easily if you shop a bit.You`ll need to overcome the turbo oil drain situation but l`ll post my results of gravity drain with stock 930 turbo location.l still haven`t heard from someone who has actually tried it weather or not it will work.

[david.avery]

Cool, thanks for the comment raceman. There were some of these parts just listed... I'd love to get to 300hp for $2500

Unfortunatly I just sprung for a fabspeed premuffler and muffler, but these are nearly as liquid as cash these days!

[raceman]

Sell those treasures! l almost completely financed my turbo conversion with the sale of my GHL exhaust and Autothority Mass flow. lf l went with a used 930 exhaust instead of the B&B l would have even had change left over.l got used to the look of an aftermarket stainless exhaust though and just couldn`t bring myself to go back to stock,even 930 stock.l can`t wait to get this conversion done test drive it,hopefully before the months end...

[raceman]

And one more thing,l `ve found that it`s possible on the 3.2 turbo conversion to keep the aux.blower in the engine compartment when using an intercooler.l`ll post pics but with a little modding it works perfect and saves a lot of backdating engine tin.******David Avery l sent you a PM********

[dickster]

fwiw, the "on the side kit" is not listed on their website.

Basically, you take digital pictures of your exhaust system and he figures out how he can accomodate a turbocharger by modifying the parts you have and suggesting replacements where needed.

as far as i am aware this is not the case at all. the kit is $5,400 (last time I asked) and is a bolt on kit, including J pipe in place of the cat/premuffler.

for that money you get proto's well tested setup, and a modern turbo well matched to the 3.2 (not an old 930 job).

seems like good value to me. you will have to email proto for details.

[WydRyd]

OK, you can use gravity drain if the turbo is in the stock 930 location (only higher). "Mike the mechanic" has done just that with his TT setup. OK, so it's not exactly in the same position as the 930turbo, but his two turbo's sit right in front of the chain cover and he's draining into that.

Mike, chime in please!

I personally would have like to go for a proper set of Protomotive headers, but I couldn't afford it at the time, so I went down the J pipe route. It didn't limit my top end HP for Stage 1 Upgrade, but I'm not sure about the Stage 3 I have now. I guess the Dyno run will reveal all.

[charlesbahn]

I'm just relaying what was offered to me by Protomotive when I inquired last January.

In any event, at that time and in my case, Protomotive was willing to look at what I had and come up with something less than the cost of Stage 1 as an option. Although I went with the Stage 1, I appreciated their willingness to be flexible and work with me in making a decision.

[YermanCars]

As I said before, you pay for what you get, in may run now but you will be spending twice as much in the future fixing it and replacing parts

How many miles are on your cars ?

Hows the trans and clutch?

do you have any leaks?

What kind of p&s do you have 10 or 11 fins

Boost guage, a/f gauge or egt

tune up

Dynoing, tuning

These are all questions to consider

But In the end it is all worth it

[david.avery]

Another issue... emissions... how are you guys doing it? I imagine visual inspection will immediatly fail.

Get this, CT is now implementing a new system. It's been suspended for months now, but check this out, note red section:

Fraud Prevention Measures - What Procedures Are in Place to Protect the Public and Integrity Of the Program?

The program relies on cutting-edge technology to give the Connecticut Emissions Program an added measure of integrity.
Before each test, Certified Testing Inspectors' identifications are confirmed via a sophisticated verification device that actually scans their iris for positive ID. They will also have bar-coded identification cards. There will be three surveillance cameras photographing every vehicle during each test, ensuring the proper vehicle is inspected. The DMV will actively monitor the testing process on a real-time basis via the three cameras and the Internet. In addition, each test site will receive periodic covert visits by a DMV representative.

Anyone remember the books/TV movie "Logan's run"? Next thing you know, they'll be embedding crystals in our palms, and exterminating us at age 35.
