Re: BBC rear main leak

I get what you’re saying but it could have affected the way the two seals meet and created a problem. I guess we’ll never know. Never been a fan of silicone in an engine. Sorry.

Re: BBC rear main leak

Felpro: STEP 5
Put a tiny dab (1/8" or smaller) of RTV on each end of the lower seal, where the seal ends meet, taking care to avoid the sealing lip. Less is better in this case.

Re: BBC rear main leak

With the seal pushed out from the silicone it may have worn it off. Looks like a sloppy install I’m sorry to say.

Re: Oily piston tops

It highly unlikely it would cause an issue. Drive it and quit worrying what’s happening driving downhill.

Re: Porsche 993 twin turbo

If your driving a car on a winding road or on a track and entering corners close to the point it will understeer, you rely on throttle response to balance the car, not all corners are conductive to downshifting.... so for someone who likes instant throttle response, or relys on it any delay is mass...

Re: Porsche 993 twin turbo

That doesn't tell me gear ratios and final drive specs. Also what are your tire sizes? What top speed do you need to hit? http://www.gboxweb.com/993specs.html I think the overall tire diameter is 25 but let me check. Over 300 km/h would be fun on a trip next summer. It will go at least 290 kph stock.

Re: Porsche 993 twin turbo

It’s not how much power, it’s power delivery. High HP turbo motors can get very peaky with narrow big power bands. Just like old muscle cars older Porsches have nostalgic value but the newer the better for power and handling.The Turbo S’s were 450 and quick so that’s a good guideline. At some point...

Re: Porsche 993 twin turbo

I’m not surprised it feels slow in comparison to the cars listed. It seems like all you are interested in is straight line acceleration. The 993 Turbo was a well balanced machine capable of smooth acceleration out of a corner without upsetting the balance. Once you overpower it that will no longer ...

Re: Porsche 993 twin turbo

Nice! They are great cars as is. I have driven plenty of stock and modified ones. The stocks ones always perform and are very quick, the modified ones I’ve driven are stupid fast and pretty much useless. Reliable HP is the goal. No matter what you do to it there will always be something more modern...

My guess is this project will never get off the ground. On the one hand, you’re probably right.

Re: Value of a factory 454 LS-6 crate engine?

Long time friend of mine has a crate Chevy 454 LS-6 that he bought at the local dealer back in early 1980's. It was never used and has sat for years and the only thing he did to it was a swap to hydraulic cam. He still has the original factory solid cam it came with. The engine was never fired up o...
