Don't be scared ... took almost 8 years on pump gas for that to happen and it may have simply been a mechanical failure... even though everyone says detonation did that

EFI may help prevent that if you can get a knock sensor in there. Unfortunately, that is a huge challenge to get one that works right since they kinda have to be matched to your engine type. Maybe if you used the 3.2 parts? Not sure... and EFI is NOT my strong suite.

Best regards,

I am running a Megasquirt on my Lotus clone and I think it is great. The support forums are fantastic and it really is pretty easy to set up if you understand what is going on. The manual goes into EFI theory, and I think that helps the user understand the goal better, not just what steps to do next. As note of comparison, my dad has the older Holley multi-port EFI system and it is not very user friendly. Lots of variables are hard coded into the program and the documentation is pathetic... I have seen more in depth manual for hammers. My point, whatever control system you choose, research it thoroughly so you know what you are getting into. I hate to question other's abilities or knowledge, but one user here was badmouthing the Megasquirt system and how awful it was to set up. In reality, he didn't really understand what he was using, for his abilities a plug-and-play would have been a better route. I think he later scrapped it and went with the Electromotive since he had a local dist. Understand your abilities and make your choice.

Thanks for the advice and the information. I will consider all that I have read before I make my engine management choice.

I believe my first puchase will be new pistons and cyclinders. I would like to increase the bore size from 95mm to 98mm at 9.5:1 compression ratio, but I read that work has to be done to the heads to use the 98mm piston diameter. Is this true?

My heads were rebuilt about 4,000 miles ago and I did not want to rework them for new pistons and cyclinders. Thanks again...
