Thanks Vette,
There's no way I can see to do a cheap SC/FI setup simply because the hardware adds up. If you buy a new Eaton unit it's gonna cost you about $1,300 . A megasquirt or similar unit with the necessary controls & sensors, another few hundred, if you want a more elaborate engine management system you could spend over a thousand. This does not take in to consideration fuel injectors, ignition, mapping time & lots of fabrication time & expense. I think multi-port FI, tuned & debugged , will make the car run better & improve performance, but I'm not sure by how much & I couldn't begin to guess. I can say that my current set-up, using a single SU HD8, with a UT needle , idles & runs way better than any well tunned TR I have ever come across.
Here's a link to a pretty sharp guy working on just such a project.

As far as the Eaton blower on the "b" , I'm pretty sure they are using an Eaton M45 , designed for 2.0L-3.0L motors producing around 5lbs of boost with the stock pulley. The 2.5L of the TR6/TVR requires the M62, putting out enough to supply 2.5-4.0L.
One last note-With all of the modifications I have done there is one underlying goal, RELIABILITY. I will never get stranded with a carb & points in my car unless I blow up something major (hey, it could happen ). /ubbthreads/images/graemlins/grin.gif
