there was a little foreign car on the internet a while back, forgot the name, i think it was a 510 or something, a little beast. anyway, the dude wanted to soup it up, so he took the 60degree v6 and put in there, said the 60* is a well balanced motor, and runs strong, plus they're everywhere (kinda like 305's and 350) but he put twin turbos on it also. but i'd think with 12k you could probably get yourself a turbo 3.8 swapped in. just my opinion. Now, what type of car is that, cause if it didnt' have the 2.8 in there originally, we could be talking cheaper prices, being all we'd need were turbos, wastegates, manifolds, and maybe a different prom... but that's not to much, the turbos would be costly, but of course you could go with the rebuilt route. hmmmm. maybe after college, or during if i can save some cash. lol.

i think i might go that route with a 3.4....that is a 2.8 he used so a 3.4 would make way more power. You could actually set up a single turbo powered car instead of a twin turbo one but those twin turbos are sweet. 8.0 to 1 compression is easy to do and like the other guy said you could go find some used turbo's and go the rebuilt route. i think i could do it all for around 2000-3000 dollars and spank some tta's or v8, v10, v12 cars like they were nothing. Its all about what you want to do. Initiative is the main factor i guess.

He didn't mentioned too much about the cost of building the engine to take the amount of boost the turbos are pushing out, not to mention little mods to increase flow of the manifold/TBI combo to take advantage. Since I'm in the process of doing the same buildup the cost for the heads/porting and shortblock alone is reaching past the $4000 plateau. The TEC system he's refering to is over $1K. Since he added 2 turbos the price jumps up significantly in addition to the blowoff valves and additional plumbing.

12k dosen't seem to far from real. He didn't mentioned the amount of HP this combo was generating, but making a guess I would say at about 14 PSI it would probably be near 350. But this is without knowing is cam grind, flow statistics, cylinder bore size, etc. I calculated my setup (@14psi)to be 400+. It can be easily boosted to 20+. For those that say "yeah, but for that price I can buy a 'vette' for......", well then buy your vette. But if you happen to be pulling up to a red light next to an unassuming '88 Camaro Sport Coupe, that contains a 3.4L single turbo setup capable of an easy 450+ horses and happens to blow your doors from here to the next intersection, you know what you can do with your 'vette'. Wouldn't it be a challenge to try to explain to your girl friend siting next to you why your $50K Corvette got it's doors blown off by a poor lowly Camaro? Oh and incidently, have you checked the latest prices of what ZR1/L06 go for these days?

Now remember, there is no engine on the road today that sits underneath a hood of an emission legal vehicle that cannot be given a boost of about 6-8 psi, including the 2.8.
Using a single turbo configuration and doing without the TEC, the costs of a turbo install is reduced dramatically. Of course, no insult intended, but projects such as these are not intended to be done by college kids with limited a budget.

you were probably talking about me, and theres no offense taken, more likely than not this would be something that would come farther down the road, cause there's nothing worse than doing a job half assed. But a beauty is that my college as an automotive technician degree and a crapload of computer stuff for cars, including a dynomachine, maybe i could talk to the professors and see if they have any ideas, for a project. heh...university funding wouldn't be bad either.

yup same deal with me......

i am going for auto mechanics 2

my plans are a tad bit simpler

3.4 with raised compression
forged pistons
cam
rockers
porting (maybe)
ram-air
pulleys
MSD

i'm gonna do the engine first
that is, the 3.4 with new pistons, cam and rockers and the rest as i feel like it

oh i was thinking about sticking with the 60 degree v6 design so the 90 degree ones might be out of the question.
