i picked up a 130k 87 shelby daytona z turbo 2, it has new tires and the only rust holes are the size of a quarter on the floor pans. all for 300$

i have an aftermarket tubular exhaust manifold from an 87 GLH charger i so regretfully gave away (everything was broke) and an aftermarket computer ( mopar performance), the computer is installed, the manifold has yet to be, what does the computer on these control anyways?

it has a vaccume leak, i found the one near the wastgate solinoid (ya it pegged the guage) and now its fixed, but i still have a vaccume leak, when driving i can hear it from in the drivers conpartment, but as soon as boost happens it goes away max is 7psi, the car will only peel out if i dump the clutch hard and then its just a skwak, its kinda gutless.

and what can i do to prevent this car from breaking/stripping axles? i'v heard they are notorious for this.

Everything.

max is 7psi


Either the Turbo is shot, the wastegate is stuck open or the air is leaving somewhere.  Should do 11 PSI stock, 15-16 with a stage II computer.

They are, and there's really nothing you can do about it axcept spend a ton of money on custom halfshafts.  I've been through more than I can count on my 87 Shelby.

Center your engine. That will help with the broken axles. I have yet to break an axle on my RT with a properly centered engine and solid motor mounts. Also, if you are wheel hopping on take off, that will do it. Wheel hop has broken more axles than hard launches at the track with slicks EVER will!
87' Shelby Z's have a really nice stock computer in them, you should be right around 13-14 psi stock. I would check your wastegate vac lines and go from there.

A stock TII car will push 12 pounds of boost..

You want to keep from breaking axles..follow this rule..

Axles don't break that often unless a few things are out of whack.

1. solid motor mounts
2.aline the motor/mounts

the air noise your hearing I'm banking is a hose that is off or maybe a hole...if you had a vaccum leak your boost gauge would show it
at idle.. do you live in Ohio?

I've been working on these cars for nearly 20 years now and I can tell you pretty much what to expect and when to expect it.
