Sorry for the post but i did a search and came up with only one post on this. Here's my problem. I thought I got a great deal on a 93" 454 whipple supercharged motor without the wire harness and electronics. Now I have added a edelbrock cam and manifold while keeping the block and heads stock only upgrading the pushrods but I want to run 90lbs injectors in the tbi. What type of numbers can I expect from this. I don't know what system I can run. Also my trans is a lt1 t56 and this is going to go in my 75 laguna with NV aftermarket gauges. I need help in a system to get this thing running. Any advice?

I don't know what kind of actual performance you will get, I'm guessing somewhere close to 400HP.

If you're looking for a TBI computer that will work with the supercharger, I would suggest the EBL system ... http://www.dynamicefi.com/

For the wiring harness, I would suggest getting a new aftermarket TBI harness for the 1227747 TBI ECM. The EBL system will need a few wires from the 1227747 wiring harness re-pinned ... http://www.dynamicefi.com/RePinHowTo.php

I don't know of any "Salvage Yard" options for a TBI computer that will work with a supercharger. If you have good wiring skills, then using a "Salvage Yard" wiring harness could be an option.

Dave thanks. I didn't have a clue on this. I hope to contact whipple for a prom or custom tu
ne but I am wondering if I can still use the t56 transmission. But I know which direction to go. Thanks again.

I don't have any experience with the T56 transmission. I'm thinking it could be used with a 454, not sure how much horsepower and torque the T56 can handle?

The only supercharged 454 I have experience with is at this tread: http://www.gearhead-efi.com/Fuel-Injection/showthread.php?501-PCM-Options-for-Supercharged-454-4L80E
