1990 Coupe - 'budget' turbo kit

[sosoe]

Brooks, When welding axle tubes does the rear need to be on some sort of "jig" or table to have it all squared up, Since I've heard when welding tubes to housing that the heat will bend up the tubes or something in that nature. Idk, I'm just curious and decided to ask a fab guy...

Ok cool. Got it..

Yes, you 'should', but I didn't and normally dont. This particular kind of C clip uses a ball bearing - it will be perfectly fine if it's out of line a little bit. Now, I have the jig setup like shown above, but it's not for this kind of rear end. I don't do a lot of that kind of work, so it's not a must have tool for me. In fact, I don't do that ONE job for anyone but myself -I've never had a problem with it, but there's always that possibility.

ahh grasshopper you walk on rice paper
and I am with grape, wiggins suck. on larger tubes if they are not perfectly round they are a bitch to install. plus having to carry shit load of extra orings.

Hello Chris and Greg.

Whats up Clifton?

The car moves under it's own power now. Got the rear end all put together, setup, painted, and brakes bled. The brake bleeding was NO fun.

This pic shows the retainer straps that keep the hoses from blowing apart. (bolts not installed yet)



Next, Rear end parts sitting on the table waiting to go to their new home.

Verifying end play for the last time...



assembled and just about ready to go to it's final destination...



Money shot -



Money shot #2.



Cheap ass brake lines - see a problem?



I see the problem!! (luckily this happened on the jackstands)



loaded up and ready for the dyno!!!



Last but not least, the dyno! It was relatively problem free, everything pretty much worked as it's supposed to - this is only the first pull, we didn't record all of them. The smoke is from about 4 drops of oil on the crossover pipe. The turbo drain was leaking for some reason. I had a consistent problem leaning out, and didn't figure it out till it was time to go home. (the PVCR's are too small). For some reason I thought my carb 'recipe' said they were supposed to be .0625, and in fact, they should have been .095.. Doh.

Nothing special -
