Pointless conversion.

Again with the helpful posts eh?

It might be the best conversion ever and make a billion horsepower. We would still be driving around in 133bhp standard gts/glanzas if no one tried new things!

twin turbo 4e

so today i bought a nissan skyline t3 ball bearing turbo,which i'll be using besides the ct9
sequentially, now i'm thinking about 2 ext wastegates 38mm or 1 actuator and 1 wastegate , any tips ?

I would have thought twin turbos and one external wastegate ..

saw a pic of a quad turbo setup a while back, 4x td02 turbo's
insane spool up and decent power too. sad those turbo's are quite expensive, otherwise it would be a nice build to try :)

The only reason why a engine is twin turbo, like the 2JZe and the RB26 is mainly to get super boost response by a big engine using 2 small turbos. This does not need to be applied to a pissy little 1.3 litre engine. Its simple as that.

If you want to run 10psi on a twin turbo setup 4efte, each turbo would have to push 5psi, so why not just use a single turbo pushing 10psi. The 4efte is not a big block equivalent 4 cylinder engine. twin turboing a 1.3 is pointless, and if you did, you would have to fit like two TD01 turbos to get the scale the same.

I aint gonna draw you people a picture.

Do you even understand the concept of sequential turbos?

I think not.

The whole point is use the compressed air from a small turbo to pump into a big turbo to spool it up faster. So you can run a bigger turbo on a smaller engine aand get more power and less lag

That's not generally considered sequential turbocharging, but compound forced induction. In a sequential forced induction system there is a transition from one turbo to the next, generally the smaller to the larger. They don't blow into each other. A parallel system uses dual turbochargers at the same time.

Compound turbocharging

Supra twin tubbies are both the same size and both run at the same time.

A Supra is sequential and they don't run at the same time constantly. It pre-spools and then switches to the larger turbo.

i thought skylines ran on t28's as well but my flange is of a t3 for sure, and by the way i am thinking of 1 bar boost on ct9 and another 1 bar on t3, i am still in doubt about single or dual wastegates ... ;)
btw who says it's pointless don't bother m8s u can ignore it right and let me try my thing :) cheers to all others for your support

Will need to be dual wastegates I would have though mate? As each one will flow different amounts of air. So will need to be set up individually?
