My rear end is from 94 ws6. N my tranny also

 

there should be no problems, its the same engine. only difference is the intake and a few small other things. also i dont think your trans is from a ws6 the 3800 and lt1 have different bolt patterns.

 

^ What he said. The bolt pattern is different between the V8's and V6's. So, whoever sold you the car lied to you. I'd double check that the rear end is from a WS6 as well. If it's LSD, both tires should spin in the same direction when the cars in neutral in the air. Mark the drive shaft and count approximately how many times it turns.

 

Yes that is the kit, like a said for you to rebuild your motor you are going to need about $1200 worth of a machine shop work. I am not some kid guessing or repeating what someone else said I have build 100's of motors. Your new pistons are nice about round. Your old cylinders are not. The new rings can only handle .005" out of round yours are going to be anywhere from .008-.016" out of round. So your rebuild motor will NOT seal well. If you where freshing up a motor with 65,000 miles on it that kit would be perfect but your not. The kit does not address the Valve guides and seats. a Valve job is going to run you another $600. The rebuild will cost you too much money and there are 100's of places to make a mistake.

I have no Idea who told you swapping in another 3800 causes problems. There is a very detailed post in this V6 forum about what has to be changed. I know of aleast 3 car within 10 miles of me that have the S-III 3800's in them. I guess we forgot to tell them there is problems. I swapped a 2002 SII into my 96 3 years ago and Have over 50K on it since the swap. In fact that fasted turbo 3800 on these forums is running low miles S-III still stock botom end.

The WS6 transmission in a V6 is pretty funny.

 

Ok . So I checked my rear end serial number and searched online and it came out as 94 ws6. The tranny as u guys mention is bone stock. So am I able to just put the tranny that comes with the 05 engine ?

 

Well no. As far as I remember, after '02, pretty much all of GM's vehicles using the 3800 Series III were FWD. A FWD trans doesn't work in a RWD car. Keep the trans you have now, it'll bolt up just fine to the '05 engine.

As for the WS6 rear. Other than the gear ratio in it, it is no different than any other 10 bolt build at the time. So, in other words, it is still a weak 7.5 in. 10 bolt.

 

If you just have your transmission rebuilt you can have it upgraded. The cost of upgrading at the time of rebuild is not much.

 

Would it be possible to just have a head swap and install a new timing chain intense-racing has a double roller for 99$ and I found heads for 150. And spray ? I want to save for abbot heads and cam

 

Its possible to spray your motor as it is. IMO replacing/upgrading the headgaskets is a minimun.

I don't understand, you can find a low miles SIII motor for $400-600 why mess with a 160K motor at all? The SIII motor is stronger and breaths better and if you screw up with the nitrous system you could alway put your old motor back in. Nitrous can be used safely but it is VERY common for guys to blow their first Nitrous motor.
