i started removing the transmission on my 99' ws6 today to put a yank 2800 stall just ran into a few problems....
-the bolts on the fly wheel are alen wrench heads...wtf do those need to be removed to drop the tranny?
-from the exhaust manifolds to the cats need to be removed i broke two of the three on the drivers side..after i get that removed what should i do? new pipes? now bolts? bypass the cats im not sure of what to do?
just need a lil help this is the first build i have doen could use some help from the more experienced

 

i think the allen head bolts you are talking about are the flywheel to converter bolts and the converter is also splined to the trans.

as for the broken bolts in the exhaust manifolds you have a couple options. if it were me i would remove the manifolds and try to get the bolts out on the ground or take them to a machine shop and just have the drill them out. you could also buy new manifolds. my suggestions would be get some ebay headers and a y pipe.

any way. what are the mods and why did you pick that converter?

 

thing is i wont need a y pipe because im doing an sts turbo build which has all the exhast tubing but i will probably remove the manifold bolts from the head and remove the broken bolts tht way i appreciate it

 

mods are torquer v.2 cam 115 lsa valve springs and hardened pushrods ls6 intake 55 lb injectors and 67mm sts turbo methenol injected and i went with yank because good name brand and it will be a daily driver so i picked a 2800 stall

 

Enjoy

Edit* Either way since it does have a STS, you either remove the CATS and extend the Y pipe which MOST exhaust shops wont do if you have emission laws or you get heads now and make more power and use their Y Pipe. Mate it to the STS system.

 

The 3 allen head bolts must be removed in order to separate the torque converter from the flywheel. If I remember correctly they are 8mm. I was able to get 2 of them out using a 5/16" allen wrench but the last one just about rounded out. USE AN 8MM ALLEN WRENCH. If you have a stubborn one you may want to put a little heat to it. I fought the hell out of one and finally resorted to heat. You shouldn't need any fancy flywheel turning tool. If your driveshaft is out (or the rear is on jackstands) just use a deep socket on the crank to turn it over (with the trans in neutral).

 

Also when you go to put everything back together run by your local gm dealer and pick up some new torque converter bolts. They have the provision for the allen bit in the center but are designed like a normal style bolt and you can use a regular wrench to install them to make it easier.

 

I'm not sure about the Yank, but a Vigilante convertor has to be installed with the supplied bolts. They are shorter than the stock bolts.

 

thanks for the advice every one and my buddy has the socket allen wrench tool just have to make sure it an 8mm
next should i just get an off-road y pipe? i could use stock pipes still as shown in the sts manuel.... and as for headers i was told by the sts manufactuer tht stock manifolds work better? true????

 

yeh my vig converter came with "special" bolts

 

the longtube headers dont work as well

 

yeah im gonna stick with stock manifolds for now, and just got my tranny back in now im just getting everything back together then i can start my turbo cant wait i should have it done and tuned sometime in febuary depending on how much time i have to do it all
