Modern induction & ignition on sub 3.0 motor
I’ve been looking into the EFI kit with the TWM stacks from Mike B's thread. This kit really looks promising. Not as cheap or easy as carbs, but oh well. I’m warming up to the idea of having a late 20th century mechanical skill set and nothing about these cars is cheap anyway.
Anyway, I’ve got another roller on the way to my house and I’m starting with a clean slate as far as drivetrain plans are concerned. I want something different than the 3.2 & short geared 915 that’s going in my brown car so I’ve been thinking of a hi rev motor hooked up to a 901. Henry's 2.8, a 2.6 RSR (92x66) or a High compression 2.5(90x66) are the three engines that I keep seeing in my head. Has anyone ever built one of these small displacement hi rev engines with a modern EFI induction? Most of the engines I see of this size are either carb'd or MFI with RSR distributors. I want something more exotic than carbs and I’m not going down the custom MFI route again. Very cool but too much money without the right core system. BURN-BROS distributor would be perfect, but I just scored an electromotive twin plug setup for really cheap so Id like to plan to use that. TIA Last edited by Shuie; 06-12-2005 at 07:18 AM.. |

I have never done a motor like you are talking about doing. I have only installed EFI on a 3.0L 930 motor. I will tell you that EFI is the coolest thing. You will not be disappointed. Maybe frustrated but not disappointed. The tuning possibilities are endless. (that is the frustrating part).
Have fun with your project. Dean

Send me an e-mail and I'll send you some pics of our new EFI tall-butterfly induction system. Compared to TWM, I do not think you'll be disappointed,...

thanks guys.
Steve, incoming email from my hotmail account Tim, what does 'wasted spark' mean? You need the twin plugs on the small hi comp motors, right? Or is that just for the bigger motors? |

Wow. I just got some detail pics from Steve at Rennsport. If you are thinking of buying a ITB setup you really owe it to yourself to look at the high butterflies he mentioned above. Im going back to study the pics now....

Please post the high butterfly ITB pictures here. I am pretty much sold on the ITP Electromotive setup from Clewett.
