+1 and less piping crossing the engine bay on V style engines.

 

The 4000hp integra runs twin turbos at 55-60 psi on a B18 setup, but it is rare.

I think the best thing to do would be to get 4 16g turbos and run a quad-turbo Civic. You could just stack the intercoolers on top of eachother, and the piping would take up all available space in the engine bay. Itd be totally sweet.

 

Actually, although the MkIV has a sequential setup, both turbos are the same CT-12b. Someone forgot to tell Toyota they were supposed to be different sizes!
Actually next year BMW is coming out with a 123d (not in America though)..its a 1 series with a 2.0L diesel engine and a compound turbo setup...and 200 HP! In a 2.0 diesel!

However diesels run far more boost than gasoline counterparts, therefore making the compound setup for the 123d completely functional. BMW has also had excellent experience with the new 3.0 TTD in the 335d and 535d, which is also a compound setup.

Personally, despite how much I insisted when I was younger, I will always prefer a single to twins in an aftermarket setup. A nice twin scroll setup is far easier to package and manage than twins that are of equal size, half of what the one would be.

Bigger turbos tend to have more efficient compressors, plus you dont have two giant heat sinks next to each other, affecting intake temps as well as oil and coolant temps and routing.

 

That 4000hp Integra is not a B-series motor, and it's not an Integra at all. It's a funny car. The motor is custom made and machined and has nothing to do with a Honda at all other than the cover for the frame. 4000hp B18...lol man!

 

The motor isnt custom, I swear on my life its a bored/stroked highly modified B18. The creater said they pulled it out of a type R.

 

Um...I'm pretty certain I know which you are refering to...and no its like a 4 liter 4 cylinder

 

You win this round. I swear on the original streetfire video he said it was a modified B18C5, but the new one shows the machined block. Its a 4.8L btw. monstrous.

 

depends on the system and how its built and whay engine its going in and how effincent the engine is..

i can design a single 114mm turbo that can spool fast or faster then twin 88s

they would make around the same power..but then i could design a twin 88 setup that would spool faster then the 114


IT ALL DEPENDS ON WHAT I SAID IN THE FIRST LINE..PERIOD

 

yea i remember seeing pics of the block...

 

yup..its 286 cubic inches...def not a b18
