I’ve had a chance to go through some very useful past discussions, but as always win a couple years has gone by it’s worthwhile to revisit this topic The latest thinking and experiences. Looks like there’s a trade off between buying a pre-packaged kit versus trying to roll it all yourself, while expensive having someone else have done the brain damage does have a certain appeal to it.
Any thoughts or coaching out there on this? I’m assuming if you go the route of a kit do you want to have the kit in hand when the gearbox servicing and flip is done, yes? Thanks! |

I am with Dr. Evil.
I purchased his video and built a 901 behind a 3.2, 20.3 compression, Web 20/21 cam, headers, Chipped and never had a problem. It was not babied....but no Dairy Queen burnouts either. You can have 2 backups for the cost of a 915!! But...I am a csob. |

You just use 1st as a parking lot crawler, on the highway you scream at about 3500 but that's typical 914. I was reading on the track cars that the 901's only last so long, but if you upgrade the cooling you can get them to last longer. Heck the early 350 SBC guys used them with 1st removed. A later model 915 probably suits a 3.2 better for general street driving gearing though. I think a common late 70's 911 mod is to go back to the early R&P for more acceleration. But I think 1st gear in the 915 can take a better beating. I have a mid-engine 915 sitting on the shelf waiting for a future install... Haven't decided what direction I want to go with it yet. |
