Was taking a closer look at the MSS and I like how they sandwiched the adjustable perch between the springs. This makes accessing the perch easier and can be adjusted without having to disassemble the rear and remove the perch for adjusting height, like you have to with HKS.
I had a 3.8 Track BK1. Did the turbokits.com kit on stock motor. Probably made 400whp on 6psi 91oct. Only made 285whp before turbo on 91oct FBO.
@DrSeuss has a big build in the works. 4.3L TT R-Spec BK1.
For those itching to shift, put your car in manual and paddle shift/move the shifter up and down. I always drive this way, some what more fun and a little more engaging.
