just dreaming but how fast would this be - Honda Prelude Forum

How fast would a Twin Turbo 4th gen with an H23/H22 (Vtec head on an H23). I know it would take a lot of money to twin turbo a lude.

i also think that a TT lude would be pointless, no reason for two turbos on a 4 cyl

railsldr · 10-26-2002, 02:47 PM

yea I know it would never happen because 4 cylinders are just too small too handle it.

They can handle it, but it is just a pointless thing to do.

It's not so much that you can't handle it, but why would you want to? The only real reason to go with a twin turbo setup would be because you're running a sequential setup or have exhaust ports on more than one side of the engine.

It's been done but not on a daily driver. Apexi's drag Integra uses a twin turbo H22. The motor is also mounted backwards and spins the other way if I remember correctly...

i would put a bigger turbo on before i went TT

yea a BIG single turbo is better than twin turbos....

You don't have enough powerband to get the most out of a Twin turbo setup. A "BIG" single turbo would give you more lag, but you could utilize the powerband better.

This week end at the Montreal Sport Compact Show, I saw a VW golf with 3 turbos !!!! They were very small and without any wastegates...

Preyluder · 10-28-2002, 09:35 AM

Did you find out if there was a reason they did that Blaast? I think it's stupid.

skalude · 10-28-2002, 04:26 PM

thats nuts

smoothludey · 10-28-2002, 05:27 PM

that triple turbo looks very useless. I guess you could use a twin turbo setup on a 4 cylinder, but one drawback would be the fact that you would have to split the exhaust pressure you need to spool up the turbos...especially if you have one small turbo and one big one. The fact that 4 bangers don't put out as much exhaust pressure as say a 6 or 8 cylinder motor is probably a good reason why you don't see any twin turbo setups. Correct me if i'm wrong, but inline motors usually use a single turbo since they have a single intake manifold and V-motors use a twin setup cuz they have 2 manifolds (exhaust and intake). That's why i have never seen or heard of a 300ZX single turbo setup, but i could be wrong.

Supra's have twin turbos, and they're an Inline 6.

never said there weren't inline twin turbo systems, the supra is an inline six, that's two more cylinders with ~50% more exhaust to spool 2 turbos...but for more power, they usually go with one big one. The skyline rb26dett is another inline 6 with twins. My question is, how many V6 single turbo setups do you see out there?

Preyluder · 10-29-2002, 09:47 AM

I've seen a lot of 300ZX's with Single conversions. They're v6's right?
