3800 Supercharged out of an Olds eightyeight,

ganjking

While searching the net for engines i came across this 3.8Lsuperchared for 250$ w/o tranny. Apparently it bolts directly onto a 2.8L tranny, and only has 150-170 clicks. Thinking about transferring into a 88z24, Just curious about what exactly I'd need. Also a friend of mine has a 3.1L ported to approx.3.4L with performance pistons, crank, valves, and rockers.at only 100clicks, for about the same price. He says it pushes around 225, which is the same as the 3.1L turbo, but then again its track ready.
What you think.? go charger, or high performance?

ya and you cant make a 3.1 to a 3.4 even if ya did a 3400 will still perform better due to the more open intake, 3.1L cammed or not. hey who had tha sig with the 2 intakes side by side? you will see the difference.

people have done the 3.8 super. but its alot of work and thats all i know for toady.

Im not sure on the exact specs, its a stripped out 90 Z24, with no rust, it was ported in 2002, when a new motor was dropped in. He says its somewhere close to 3380cc, i do not remember the name of the shop that did it, however i have driven it first hand, and have seen dyno runs of it pushing 225Hp, and Torque.It blew nos for a bit, but its been taken off along with the ecu, all coolant hoses crimped off, and straight pipes to the back. Shes ready for the track, but i would like to bring her back to street level, Cause fuck does she roar.! Looks like a regular 3.1L but its kicking way harder, i will definably get a picture of it.

you're dreaming if you think a 3.1 will make that kind of power at the wheels. There is no way he gained 120 HP over stock on that crappy top end without nitrous or boost.

It is possible to stroke a 3.1 up to almost 3.4L but it's a total waste of time since the displacement isn't going to add much power. power comes from top end flow, which even after extreme porting is still less than a stock 3400.

so, for your engine choices. My educated suggestion is neither. L67's catch on fire and weigh a lot, and your buddies engine is sketchy.

drop in a stock 3400, and bolt on some headers. With a proper tuned chip you'll make an easy 210-220 WHP (honest power, not ass dyno).

Its a matter of aprox. 85Hp gain off, not 120,
and the engine did run Nitro when it pulled under 13's
i talked to the guy today, so my bad about that.
But if 3400 is the best way to go, i may just have to ask Atlantic towing to find me an old rendezvous or something.?
-Then hybrid that SOB!
Thanks for everything, im still going to get a picture of that engine, and post her. Mayby ill talk him down to 500 for the engine and a rust free 90z. ?

No that buick wont have a good 3400.

The install guide has the info you need and what cars are good to pull from. 00+ are the best choices the newer the better and the lower mi/kms the better.

I hope when I put this cammed 3400 with soon to be WOT heads and LIM in it can push as much WHP as your buddy's 3.1!

We've been talking about transferring my 2.8 German made trany into his clean, rust free 90 z, with the High Performance engine, He says my gear ratio is much better and will perform much greater.
-Problem is there is no ECU, and straight pipes to the back with all coolant hoses closed off to make higher compression and heat. ( Apparently someone was running some boost... hehe )
-2010 summer, hopefully shell be rolling
What to do with the 88z tho xD
insurance at 94$ a month, cant complain.

Man, you should stop listening to that guy NOW. 3.1 won't break 200hp w/o some SERIOUS mod.

And your 88 tranny is the SAME gear ratio as a 90.

Not sure what you're talking about with the coolant lines closed to make higher compression and heat ?

Ugh, you could barely call it a 3.1
if you read the thread its all High performance.
And higher heat = higher combustion = higher power
Goto back to school , thats basic phsyics.
I want to bring it back to street legal , it makes 200+ because its a drag car.
Also Ive been in the engine bay, trust me the hoses are gone, where they would be is crimped,
so i don't know what YOUR talking about. ?
