LS1 / T56 Update #23


Recommended Posts

After a couple weeks of driving:

1) The phantom coolant evidently was just some voids that hadn't been fully purged out so now all is fine there.

2) Brakes - Toyota 4x4 up front and drums in back - not enough. Too much time near triple digits. I smell upgrade comig.

3) AC - 15-20 psi on suction and 150 on discharge indicates problem with expansion valve - it's integrated with the evaporator - $450 from Nissan - ouch!

4) suspension - new Urethane everything on its way.

5) Body - Lots of rubber seals - on their way.

6) T56 - Oops - going south - needed synchros in 6th, now needs them in 5th & 6th. Hope it can hold on a while longer.

7) Tires - 30 psi vs 36 psi and heat makes difference in wheel hop problem. Hotter and higher is bad.

8) LS1 - what a beast - pulls like a rock star from 3,000 to the rev limiter - which I've found too many times. Need to watch the tach more closely.

9) Chassis Dyno - hope to get that done week after next. Traveling this week and next week. Stay tuned for the numbers.

Understand the frustration, I'm trying to find a shop from over here, that I can trust to repair 2nd gear in the T-56 in my SS. Blew it out before I left. So now it's sitting in storage, waiting. I'm really anxious to hear just how much acceleration you get out of 6th gear in such a light car. My SS will do 162 mph in 5th, but if I put it in 6th, the gearing is too much for my motor to overcome, and I begin to lose speed.

Yeah but unlike your SS, the old Z's dont have aerodynamics on its side. A 280Z will most likely never see 162 MPH unless some serious work goes into the body to control lift on the front end. Yah a Z may fly down the road but we dont really want it to fly off the road! :shock:

I figured that, I was just wondering, mainly for curiosities sake. I thought maybe somebody had configured theirs for road racing. That's all. :)
