So wanted to share the hellfire we put ourselves through in order to get the black Z to Z Nationals this year. It starts off with Mike's 1070whp TT Z and the issue he's been having with transmissions. With this kind of power Mike was destroying OEM 5 speed transmissions while in gear. After several broken 5 speeds, he decided to try out the TH400. We bought the set up used and found that the converter could not take the power and was blowing power through it. Once you got to 7000 rpm, it never left all the way through the gears. Was a wild ride but not what he was after. After sending the converter back for a re-stall and tighten the slipping issue was still prevalent. Since we know what my red car does (570whp 589wtq) we decided to line to two up to get a gauge of the power difference between the two cars. From a roll I didn't get a nose out on Mikes big Turbo Auto before he was damn near out of sight. The car motivates. We brought it back and strapped it to the dyno. At 35psi the rollers showed 410whp. The chassis dyno may be the enemy of the th400 but we knew there was still something going on with the set up. This is 2 weeks before Z nationals. The only shot we have at a transmission that will hold the power is my Specialty Z Built auto. We decide that for the car show we probably shouldn't take Mike's Z down. Locally we call it the "test bed" which we think is great but it's not much to look at. Mike has always been about performance first and looks second. So what we have is my black Z that has been down over a year and my SZ auto trans. Came up with the idea to swap everything into my chassis and take that car to Z nats in hopes to win the dyno competiton. So here's what we're up against. Original 5 Speed have to convert to auto No Engine Haltech Installation No brakes No Bumper Interior is incomplete No Stereo or Battery Wiring We get the engine pulled from Mike's Car and ready to go in mine. This is his backup engine. We both have high compression crower crank builds that we have to finish but this is a stock crank 8.5:1 CP piston eagle rod engine with MJ modified new style heads & 400+ cams with two gtx3576 turbos strapped to it.
Engine and Transmission installed
In order to do the 5 speed to SZ auto swap we needed something that was going to communicate with the automatic transmission. I found a ESS Racing "shift at will" paddle shift kit on the classifieds for it. After a bunch of wiring we got the transmission computer up and running. Mike did some custom work and was able to install the paddle shifters on an aftermarket momo wheel and get it to work with the factory clock spring,
We strapped it to the dyno
