Me and dad are taking a road trip next thursday to pick up the newist Toy a Porsche 930 Turbo with a 450hp V8 Conversion. All steel slant nose.
1980 Porsche 911 slant nose w\450 HP
- Thread starter DRIFTER
- Start date
I wonder about the weight differential between the factory boxer engine and the V-8? I guess, unless this car were one of the Porsche factory-built, steel slant nosed cars then really no loss in putting the V-8 in the car. Handling dynamics would be interesting depending upon actual weight and balance.
It is a steel slant nose and the motor is noticeably lighter and sits lower in the case lowering the Center of gravity. as far as a collectors idem it is not. But the thing has to be a blast to drive and I love the look of the Porsche 930
I've personally never heard of any downsides to this conversion and I've seen quite a few in past years. Was the manual gearbox left or is it automatic?
I've always loved that design, and it was the first car I actually started lusting over. I have come too close to buying one on multiple occasions. Congrats on the purchase. I am jealous.
Most use a G50 transaxle, given the engine placement, installing something GM would be difficult. If it's a 901, 915, etc. transaxle I would probably avoid it, unless you're a fan of vague shifting.
The main downside to these conversions is cooling, most of them overheat, or are prone to overheating in traffic, etc.
Weight distribution is affected, but can be dialed out with suspension modifications - older 911's are already a handful, this is not going to change.
Most run a radiator in the front 'trunk' area, mounted at an angle, enclosed in a shroud, with twin high speed electric fans, then have coolant being pumped to the engine bay for the motor. Given the size constraints, almost everyone uses the same setup, and, as I mentioned, most do not like traffic... more of a hot rod, not sure how it's going to be on a roadtrip.

True it might sit lower, but it's not a 'pancake' engine. I imagine CG will be higher overall. A good portion of the engine weight is distributed up high. It'll change the vertical weight distribution, but as another poster said it probably won't be dramatic in most situations and the suspension can be tuned to deal with it.

I'm a big fan of the 1987-1989 930s; especially the Targa models.
Almost purchased a 1988 (red on black) 930 Targa two years ago, but decided to wait and find a 1989 model, as I wanted a five speed.
Two years of regret have passed since I made this decision.
In the event anyone here has a Porsche collection, I'm still looking for a Guard's red on black 1988 or 1989 930 Targa... :smile:

It uses a all new fully built 5 speed 930 trans, and has a monstrous radiator and fan setup in the front to keep the engine temps down. No issues in traffic. Temps stay considerably cool the way it is set up now.
The 930 in stock form had a tendency to under steer and with the turbo lag was a hand full to drive. The low end torque will help out a lot keeping the power up so it dose not snap overseer. I spoke to the guy that makes the conversion kit he says that by adding a stiffer front sway bars help to almost eliminate the under steer issue common in the stock 930.
Keeps engine between 190-205 deg
In traffic according to the owner. But we will see Thursday morning:biggrin:
The porsche 930 uses a 4spd transmission (I owned one), they could not build a 5spd strong enough at the time. RUF made a 5th gear conversion, and the final year of production they switched to a 5spd ('89), but I doubt either of those are what's in your car... probably a 901 or 915 transmission like I mentioned before.
If you're happy with the car, congratulations.
There was a black slant nose V8 conversion in my neighborhood years ago.
Cool rig, and I'll bet it was a lot of fun, but it must have been a handful in the canyons.

Unfortunately the car was not as clean as described and I passed on it. (700+ miles 22hrs of driving in two days for nothing sucks!) It needed way to much work for me to be happy with it. It was fast. I would compare it to a ZO6 as far as strait line performance. But whoever did the body work, did a piss poor job.:frown:
It Sucks but at least I’m not stuck with a car I don’t want. That to me is priceless :smile: The car was mechanically sound but cosmetically was not all there.
I am glad you did not buy the car. Unless you do all the conversion entirely yourself, it is almost impossible to find one that would fit your standard. You would absolutely hate the aftermarket slantnose conversion since they are all crappy with the headlights bouncing up and down. When I was younger, I built one with the help of a body man. I hated how that car turned out and I sold it soon after I finished it. It might have looked very cool, but little things bugged the hell out of me. I am sure this car would make you hang yourself.

Hence my question re is it a factory built slantnose.
It was a factory built slant nose however the body was completely striped down then repainted horribly. This is what I don’t get? Why go threw all the trouble to strip the car down, and not take you time finishing it off right?
