my dad has started lookimn for GP engines already but all he could finde was a low mialaged 2.8 (itll do me no goo to down grade)

 

Ive been told that any GM front drive V6-V8 that hooks up to a 4t60 tranny will work in my car...

 

 

can yall just tell some possible engine swap to look out for besides the L67 ? cause L67s arent cheap in west texas unless the bearing go bad in the super charger or somthin.

 

I'm realy just lookin for somthin that out performs my 3.1 but I dont want a 3.4 if I'm goin threw all the trouble of a swap I want to feelin a significant power increase

their are no TGP's in my area at all (not even in th junk yards)

 

so unless I could finde a cheap one online with the pcm 3.1 turbo is off the list.

I had one sent from Misery, er Missouri. (Props to Shawn our fearless SiteAdmin) About 800 miles. $80 shipping. So don't think you need to get a close one. Any one will do.

hmmmm

 

 

that a possibility if I can finde one fast.....My GT has been down every sence the last week of may.......That relates to no car all summer....

 

 

would be possible to swap for a N/A 3800 and latter add a supercharger?

 

like use a first series n/a 3800 and once I can finde one add a first gen blower later?

I think you would be decently happy w/ a NA series one or two 3800 w/o supercharger, they make quite a bit more than the 3.1's do(around 30 more horsepower and 45 more lbs/ft of torque if my thinking is right tonight)....adding a supercharger later really isn't a great idea being that the supercharged motors are fairly stronger than the NA versions of them and most people just say it's easier to go w/ an entire supercharged motor than to convert a NA one to a supercharged one the right way, but, I guess it boils down to what you're willing to do. :wink:

If you don't want a 3.4, just wait it out and save for an L67, imagine 240hp on tap whenever you want :shock: I waited a year for my motor, but we did it right and slowly but surely did an awesome rebuild on a 3.4 DOHC. I think it was well worth it, and L67 woulda been fun too tho :D

^^^^

 

 

I hydro locked my 3.1 and wrecked one of the heads. I currently have the top end broken down....

 

 

the previous owner had already did some mods to the engine or atleast I think he did cause my 92 3.1 has alot more power then the 3100 in my brothers wifes lumina.....thiers a sticker under the hood that gives the vin number for a larger fuel pump witch is on the car...but I got the car threw a lean(he had my dad do some work to it and never payed)

An N/A 3800 is a good idea, there is a guy down in Indy that does NA 3800's. He can get ~280-300 HP w/o too big of a deal. I have a 3800 on the chopping block right now, getting ready to send the heads and block out. Now that I have my turbo motor I might keep that one NA. (Who am I kidding?) We shall see.

I dont have to have any custom harness for a 3800 swap do I

 

 

cause series 1 3800's are a dime a dozen Down hear...I could probly get one with the harness and pcm for around $400 and less if I say my dad sent me to get it (he's a popular mechanic in my town

 

I havent seen too many series 2 N/A engines for sale

 

 

 

but I could get a whole 96 cutlass sedan that has an L67 for $650 but I the engine may be damaged cause they have a shorter belt on witch is bypassing the blower making it a very shitty runin N/A 3800

righte now I'm favoring the 4.9 caddy over a 3800 engine

 

 

I drove my dads friends 94 large body Sedan Devile this morin and that thing has to out way my car by neer 1,000lbs but I was shocked at the power that thing was puttin down.......it threw me back in the seat like It was a sports car..

 

his caddy also has the 4T60 tranny he hasnt had any problems in the 4 years he has owned the car.

 

I can only imagin what a 4.9 will feal like in GP coupe the only thing I think I'ma have to wrry about is cooling and exhauste....

 

cause we have a surpluss of caddy wire harnesses, PCMs, cooling fan, radiater, etc. cause my dad makes money on the side selling caddy parts to people.

 

 

so it's gonna be a caddy 4.9 unless I can finde a a cheap engine puttin out as much power stock....

They only have 200 horses dude. The have a boatload of torque like 275Lb/Ft. I think or more but they get like 13 miles to the gallon. My friend has one in his Seville and it's not that great. Plus I don't think that thing is gonna fit, not to mention your car will understeer something awful with that heavy chunk of metal in there.

Nevermind I guess they will fit from what I've read but it looks pretty damn tight.

 

yeh it is a pretty tighte fit but the low end torque is worth it

 

 

and I wouldnt be taking the thing on any race corses a the understeer couldnt be that bad

Well Ive been having trouble convincing my dad that any w-body v6 would mount righte up in my engine bay (thanks to to a computer illiterate dumb ass at the salvage yard)

 

so now my parents wont carry the bill for unless I get a an engine out of another GP.

 

My mom found a totaled 93 GP SE that looks exacly like my 92 GT(the previous owner rebaged my GT to SE) .........

 

If get the parts cat I'm hoping it has a 3.4 engine in it....and leather seats or atleast power so I can replce the motoer in my drivers seats cause somtimes it sticks.

 

but atleased it has laced wheels cause mine has the ugly pentagon alloys.
