it was on a superflow dyne, so measured at the hubs. Heads were match ported to the blocks and manifold. I was running GHL headers a zork, and a comp turbo CT63 triple ceramic bb. Your turbo choice is very important, that was my key to efficient HP at lower psi.

Project underway.....

All suspension is off, interior stripped, motor is out and apart. Windows come out tomorrow as well as a few more bits and off to the body/paint shop.

All new suspension parts have arrived, interior parts inbound, heads and case off for work. Motor parts are starting to come in. I figure four months and it is back on the road.

All original parts not going back on car are bubble wraped/boxed and in storage.

Will update.

Boy, that's gonna be fun!!

I had a 1977 ROW 3.0L 930, stock pistons/cyls (6.5:1?), rebuilt heads (no special machining), SC cams, CIS, Garrettson intercooler, 0.8bar spring, K27-7200, GHL headers (w heat), stock 4spd gearbox w/LSD...~325HP (all math, not dyno'ed). I was spooling at 2900 and full boost at 3500-3600, shifted at 6000 RPM on the track, very fun, yours should be a blast!!

One question though, are you going to upgrade your brakes? I don't think you'd be very happy with your stock S calipers slowing 400 ponies.

Good point, and I would 100% agree with you if I were tracking this thing. It will be a weekend back road/starbucks car only. On my 2.7SS/264 RWHP ST I can lock the brakes up (I don't) anytime I want and I am running the same brakes. The 3.3 turbo brakes as you know will not brake that much better, just for a much longer period of time such as in track use.

I am going with getty front and rear bumper blades, lexan back three, light weight interior, Hoosier R6 tires and trying out Erics/PMBs alloy rear brakes which all should reduce weight a bit and help braking.

A turbo chassis with the wider rear arms will not accommodate 11x15 fuchs at the rear with standard offset. You need custom offset to fit 11x15 wheels at the back.
I think you can fit 9x11fuchs in the front on early turbo (until 1980MY when the hub incorporates the 21mm spacer from the factory) provided you retain your OEM S brakes.
To resolve this issue, and to somewhat reduce the cost of changing tires, I fitted 8&9x15 fuchs on my 930.

1100 Sport,

With an RSR/930 body car, no spacers, and standard 911 hubs/suspension, the factory 73RSR offsets are very close to what you would want: 9"et+3, 11"et(-)27. The Braid 15" RSR changed it slightly on the front: 9"et(-)3, 11"et(-)27.

The above offsets that Braid provides works just fine...... There are a few cars (930) in my area that run this set up with no issues.

1100Sport,

Forgot to mention, the big factory installed spacer does have to come off.

Thanks

FYI,
I ran a set of 15x11 Fuchs wheels with 285/40 P7s on my 75 930 with no spacers. I think the tire selection today might be the problem with getting the correct clearance.

That's interesting. Was it a tight fit and were you using the OEM small rear calipers? A pic would be fantastic ;-)

Rear suspension slowly going on, long wheel studs and PMBs light weight rear alloy caliper. This thing is less than half the weight of the stock rear caliper.

Jimmy,

I don't want to keep asking you tech questions in your Braid wheel FS thread so I moved over to your build thread.

You mentioned going with a +24 offset on your rear 11x15 Braid wheels. Will these +24 et wheels be used with or without the factory turbo rear spacers?

I would have thought a 11x15 et 0 without the turbo rear spacers would be a good fit.

Please let me know. Thanks!

ive got 3.3 cylinders and pistons on a 3.0 making it a 3.12
you can probably find some pretty cheap.
Getting higher rpms then the longer stroke, i guess makes the engine consume at least as much air or even more then the 3.3.
Con is that the heads probably gets warmer from the higher rpm, and is a thing im concerning about right now as iwe now converted mine to EFI and get more power.
My engine ran on 1.2 bar with a k27/k29 before so i think with more fuel it should run cooler on EFI then on CIS or?

Anyway ive been running on singel spark (temperature) and titanium retainers (dont know what kind of valve spings) and iwe been way over 8000rpm several times when i just got the car (which is where my gauge stops), but after i while i made sure to not go over 8000rpm. (no rev limiter before efi)

I havent realy pushed the car on efi yet as i know my 915 transmission is the first thing to break, and i dont know what my internals can take in heat and power.
Right now my sachs performance clutch slipped in third as soon as i got boost on 80% throttle :P

Looking for a reasonably priced 930 transmission now. anyone?

Kaefer,

The 15x11 +24 wheels are used without that big spacer. A small spacer might be used to push out for fine tuning..... Funny thing, I picked up a set of 15X9 Fuchs and now am struggling with weather to use them in the rear and a set of 15x8s up front.... My friend with a RSR build underway hopes I do, he wants the 11s, decisions, decisions.

The good news is I have almost all of my motor parts back with the exception of the heads which are at Extreme, but they say they are close to done. Intercooler and injector blocks are enroute acording to Turbocraft and my flywheel needs to be balanced on the crank, thats it and then the motor starts going together.

Body work/prep/paint should start next week

Will take pics as things get going
