I am have been in the process of building a Single Turbo Rover V8 setup for my 1977 TR7 FHC.

The motor will be a stock rebuilt 3.5 Rover with std compression (8:1) which is ideal for the turbo application. I will be using Cometic head gaskets,in which the heads have been shaved down to accommodate the extra thickness of these gaskets. Erson cams has designed a special grind pattern for the application that will be suited for the turbo application with power from 2500-6500. A Holley 650 blow thru carb from The Carb Shop setup specifically for my setup. The Holley will sit on top of a harcourt single plane intake manifold. The setup will be intercooled with 2.5in piping. I will be using rover manifolds that will push a single Garret To4b turbo designed to run efficiently at 10-15lbs of boost

The transmission will be a stock rebuilt Rover trans LT77. The cars already has The Wedge Shop Mustang rear end conversion and all the other goodies.

I will update the thread over time with my progress. I plan on making the turbo setup into a kit in which anyone can bolt on their stock 3.5 with no modification and push 250Hp to the wheels.

P.S. The end goal for this car is to become a GROUP 44 Replica

Here are some more specs on the setup.

Blow through sucks... Go for a lucas intake manifold and megasquirt EFI you can trigger off the coil. Also you could pull the velocity stacks off, make a custom plenum and put a disco 2 throttle body on the front of it. Other than that its bad as hell.

 

Thanks for the advice. The decision to go blow through was partly price, partly the ease of installation and some local knowledge around the setups. Should be running in a few weeks and I will follow up.

Thanks

Awesome project!

 

Finally got the car running correctly. The car runs and drive great with excellent throttle response and driveability. Below are a few videos that demonstrate that. As soon as I have some dyno numbers I will let you know.

Had to change out the carb hat and for the time being cut a hole in the hood.... Not my first choice, but had to get it to The Roadster Factory show and not having a hood that closes was not an option.

Here is a quick 3rd 4th gear pull. Car runs strong and am expecting 275-325whp when I get it back to the dyno.

Getting into Boost

Driveability and acceleration





Thanks

Car made 278whp & 305wtq @ 10psi. Still has more in it with some added boost and timing.
