Supercharged 21 Turbo (J7R) Powered Mid Engine Kit Car

This is the blog for my J7R mid engined kit car project.

The car is built from a tubular steel chassis with aluminium panelling and a fibreglass body. The engine is Mid Mounted and utilises the renault transaxle.

When i purchased the car it was originally fitted with a 2.2 J7T engine which i have removed and am fitting a J7R.

When registered, the car weighed in at 950Kg though i have removed a lot of weight by taking out unnecessary equipment and functionality. The planned completion weight is beween 850Kg and 900Kg, and a power figure over 200hp at the wheels.

Currently, the enigne is destined to be supercharged with a megasquirt controller. A turbo may be re-fitted at a later date if the desired power and torque is not achieved with the supercharger.

BIG Thanks to AndyQuadra who is advising with the technical aspects of the engine., and to "Barry" for the laser cutting.

    Having managed to muster up the enthusiasm to tidy up the tools from the old mans garage and charge the cars battery, I managed to test the newly fettle brakes and it now stops on a six pence!!

    Collecting the car tomorrow, so that it can be home for Christmas. Should be a nice sedate drive with the new quieter exhaust.

    Well, im there. I'm sorely tempted to drive it to the MOT station as is, but really should have a working alternator first! I am waiting to see if i can get a known good (new) alternator this evening before i buy one. Here is the car;

    Time for another update i think!

    Well mechanically, all i need to do is get a replacement alternator as the two i have are fooked. The throttle return spring idea i am particularly happy with. :)
