Turbo charging an SC

OK, I must be going mad. I have been searching for over one hour now. I remember there was a really good detailed discussion on here regarding turbo charging the SC 3.0 engine, containing lots of details about how to do it and what to look out for... And now I can not find it

search help...

Hi if you search: "tsuter turbo" you get a lot of hits including some of the other fine jobs that have been done by Patkeefe, iamchappy etc. etc. AND mb911 (sorry):-)
good luck
Jesper

and me.. I can come up with an easy list for you and make it much more simple then the BAE kits or the likes. remember we use to make complete kits but just supply some of the parts now..

Best solution

930 CIS set up complete
j pipe (930) that connects to you HE so no cat in place.
k27 turbo or a t3/t4 garret maybe a gt30.
oil supply and drain line(still fairly simple stuff and I have a bunch of parts
muffler (can use stock ca style if you need a cat)
waste gate either stock 930 part or tial
IC either stock 930 part or B6 etc
second fuel pump(rear mounted)

Limit the boost to .6 bar and have fun.. tough to keep the tires in traction

not sure did not see the specs but this is what I have T4 TO4E .69 A/r 57 trim

and this is the same one Jbrinkly just posted dyno sheets on the turbo forum just a few days ago running .6 bar he had 325hp@the wheels which is pretty good.

930 guys run gt30 and gt35 or kkk k27 or kkk k27 7200

Hope that helps also I just wrote up a big explaination on how to do this on coolcavaracing.com forums so yo can search that if you like

Look I built a kit for my sc from scratch.

1. Use a volvo turbo boot, Cut it, fit a pipe on to it with silicone for good seal, boot is from the cis plate to front of turbo.
2. Make a pipe from outlet of turbo to a Carrera boot . It will work up to about 9 psi, but will eventually burst.
3. Put a fitting on the volvo boot pipe for the air regulator/choke.
4. 930 pipe must be cut and repositioned as it will not clear correctly.
5. Wastegate your choice.
6. Fuel system: modified warm up regulator (Still have a bunch left over-reduced control pressure); shims in the fuel pressure head, increase to about 93 psi. Set CO 3.5
Cold start valve hobbs switch at 4 or 5 psi.
7. Timing MSD with BTM or reworked distributor(distributor works better). No more that 16 17 a full advance.
8. Drain line, tap fitting into sump plate under oil pump pickup. Oil line from idiot light switch to turbo feed.
9. Seal injectors down as they will eventually push once at 9 psi.
10. Replace all vacuum/hoses as the pressure will find the weakest point.
11. Turbo T4/3 hybrid I believe it was a .63 a/r rear, stage 3 wheel hogged out; 60 front H3 compressor E too big for 10 psi and under. Full boost at 2800.
12. Pop off valve on air box, seal with silicone sealant, so after your done you can use it when stock.


Run 9 psi, walk stock turbo or slighty modified one on both bottom and top end. Show Saleen Mustang why he should not taunt old man in SC.
Scare Highway Patrol, on freeway as to why he should be paying attention to traffic, and not talking to his partner about food and women.

Make about 300-325 hp and about 370 ft lbs of torque. Everntually blow head gaskets on tired engine, turn boost up higher to compensate have even more fun, then rebuild after 170K of which 70k was with turbo.

Sell Car, as is becoming too dangerous, constantly at triple digits. Too much torque strips ring and pinion and tranmission now sounds like supercharger.

Leave kit in closet for 3 or 4 years, get bored; modify original SC Kit to fit in other Porsche Carrera with 7-8 psi, fast but not rocket, turn up boost to 10 psi, walk friends 400hp supercharged 350Z, but only happy for short time, now gathering parts to rework engine, make 400 plus hp, happy for short time again. Sell Carrera, then buy used F-16 only happy until next fill up; if I could only find a set of fuchs for it.

I was impressed with jbrinkley's dyno sheets, and MB911 is probably in the same HP range. Mine is SC with CIS, which is believe is a bit limiting regarding fuel delivery. However, the CIS SC will also make lots of power, and it's pretty much lots of fun to drive. Goes good at the track, too.

This photo is the rev 1.0 setup. Current Rev 2.0 setup has M&K muffler (very light weight) and Tial Sport WG, still the old Rajay turbo, which I believe we have determined to be equal to T04B in "V" trim. I think current power levels are in the 280 RWHP range at 5.8 PSI...I'm still sorting the fuel delivery.

Hi mb911,
I haven't chime in with you for some time now. Too busy with the 3.2 rebuild and my 2 year old daughter. Now that she's a little older and independant and my rebuild is done, I have been concidering using your "kit". From your post above, you state that you supply some of the parts. What part do I have to get? I will not be using the CAT. Any pictures of the kit will be great.
Thanks
John

This probably isn't what you are thinking of as it refers to a 3.2, but it is a good writeup:

Thanks dw1, very informative. But, as I remember, mb911 kit was far more easier to install. Almost "Bolt on" and require little cutting.

mb911 - what cost would I be looking at for you to source all the parts for me? I'm running a stock 3.0 from an SC. I don't need a CAT. I'd prefer a low pressure turbo (quick spool-up) and no IC.
