frozen_flame77 Posted March 28, 2005 Report Posted March 28, 2005 I was just looking about upgrading my engine and I figured a turbo is a pretty good idea. The thing is, there is DEFINITELY no turbo kits for a 93 cutty, and i was wondering if you could use the turbo setup off a 3.1 turbo or not. If not, any other bright ideas? Quote
digitaloutsider Posted March 28, 2005 Report Posted March 28, 2005 You're better off swapping the whole LG5 and 4T60-HD then bother with putting the setup on your LH0. The turbo would eat right through your tranny. Quote

Guest TurboSedan Posted March 29, 2005 Report Posted March 29, 2005 No you can't use a turbo off of a 3.1 turbo to turbo your 3.1 to make it a 3.1 turbo. huh? yes you can turbocharge an LHO using LG5 parts. i just got done doing exactly this to my LH0. the only difference as far as CR goes is in the heads (however, '89 LH0 engines had the same heads as the TGP LG5 engine so IOW an '89 LH0 has the same 8.8:1 CR as the LG5). the LH0 also has weaker pistons than the LG5 and it uses a Melling HV oil pump. the crank is supposedly stronger ie. surface hardened, but no one has been able to prove/disprove this as far as i know (i'm betting the LG5 has exactly the same crankshaft as the LHO). the LG5 and LH0 are remarkeably similar internally, my main concern is the pistons (i just installed a Melling 95HV oil pump so i have that covered). as far as the tranny goes...i really don't know about the automatics but i wouldn't trust a non-TGP 4T60 automatic. i am using a Getrag 282 5-speed and i would suggest using the 282 5-speed over any automatic. any questions feel free to ask. all of the details of the swap are still fresh in my mind. EDIT: can we please keep this on topic? :? Quote
frozen_flame77 Posted March 29, 2005 Author Report Posted March 29, 2005 so basically, all i need to do is get the turbo set up from a 3.1 turbo and slap it on my 3.1? Quote
Jeorge Posted March 29, 2005 Report Posted March 29, 2005 acctually the Cranks are not the same HOWEVER> the Crank in the early vans apv ect... with the 3.1 TBI is the same. it was a hardend crank to prevent wear and was part of the close tollerance. in the TGP. Quote
Jeorge Posted March 29, 2005 Report Posted March 29, 2005 oh and your stock crank should work just fine anyways. Quote
95 3-4 Posted March 29, 2005 Report Posted March 29, 2005 Sell ya everything ya need off the TGP for three an a quarter+shipping Quote
Jeorge Posted March 29, 2005 Report Posted March 29, 2005 Sell ya everything ya need off the TGP for three an a quarter+shipping at that price I would almost Drive down there from here to take that deal... Quote
95 3-4 Posted March 29, 2005 Report Posted March 29, 2005 at that price I would almost Drive down there from here to take that deal... You want the wiring harness with that too right Quote
95 3-4 Posted March 29, 2005 Report Posted March 29, 2005 1990 with 100k turbo very clean on the cool side, almost looks lightly polished Quote

Guest TurboSedan Posted March 30, 2005 Report Posted March 30, 2005 this is about turbocharging an LH0. the next person to go off topic gets a vacation Quote

Guest TurboSedan Posted March 30, 2005 Report Posted March 30, 2005 Why not? http://www.w-body.com/forum/viewtopic.php?t=12387 we have details... Hardened Crank (Nitrided), Nodular Cast Iron with journal camfer/deep rolled fillets, casting 981 but this one IS unique to the 1989-1990 TGP and TSTE, worked on after starting as a 981 crank! Part number 10110549. Ion Nitrided/hardened depth of .02"-.03" raising surface hardness from 30-35 Rockwell C to 60 Rockwell C. that's not hard proof. i know Jeff knows his shit but just because he says it's so doesn't mean it's true. i just find it very hard to believe that GM would go out of thier way to do any special work to the 981 crank for such a limited production car. if the crank is indeed surface hardened, than cool! i have a TGP crank in my garage right now until i see hard proof that it is though, i am going to believe it to be a run of the mill 3.1 MPFI crankshaft.

Jeorge Posted March 30, 2005 Report Posted March 30, 2005 he is not the only one who says....does anyone have the Press kit I think it says in there.... also in several mags in the 89-90 years had articals and they too stated about the differant crank. Quote
Guest TurboSedan Posted March 30, 2005 Report Posted March 30, 2005 now something like that would convince me.... Quote
