The Earlie TE chassies are great, the only thing that sucks is that headders and other performance parts dont exactly fit on them, The cams and such do and any t series head can be interchanged with the2t that comes in them, You will have to get early t50 tranys to spline into your driveshaft, and you also need to be aware that brake parts are only early TE2x cars dont grab ke2x parts they do not interchange, you can make some stuff work from TE3x and maybe from AE stuff but have not verified that yet. The T series can make the power, we made 115 with a cam and carb swap on a 3t, at the wheels. And that car feels awsome and also they can make bug numbers on boost. They have leaf springs in the rear so it kind of stuck for really fancy rear set up. but i have seen a TE21 win at scca national level a couple of years back,
it was AMAZING.
