The launch on a heavy turbo 4 car is crucial. If you bog, you're dead. If you wheelspin and then hook, you're dead. You have to find where your car will hook without spinning. I have 170k on my car so the suspension is a little softer than yours so it hooks pretty decent on BFG Radial TA 235/60/15's. Set your shocks on soft to hook better. I do a very mild burnout to clean the tires up. If the track is slippery, I may do a slight clutch slip where instead of dumping at 3700-4000 rpm's, I let the clutch up slowly, around 2 seconds to let it up. This beats the crap out of the clutch though. The best thing for you may be tires. I have never run sticky tires and have pulled consistant 2.0 sixty foot times with street radials but I could probably do better with drag radials or slicks.The other thing is the turbo. You have an Ishi-Warner usually referred to as an IHI used in 87 and 88. I have the stock Garret T-3 used from 83-86. The IHI comes on very hard and fast then falls off where the T-3 comes on a little slower but pulls harder through the top end. This my help account for why near stock 87-88 TC's blow the tires loose then fall on their faces while an earlier car can launch at high RPM and then boost kicks in and lets it rip.I have seen cars with identical setups to mine except the turbo run about 3 tenths slower due to the IHI running out of steam.
