Are their any twin scroll twin turbo kits available for the 350z?

 

twin scroll? like the dead sea scrolls?

 

 

???????????????????

 

No there isn't. and there probably won't be because the division of the cylinders would be unequal. you wouldn't be seperating 4 cylinders into 2 turbos you'd have 3 so there'd be one that doesn't have the additional pulse.

Now if you were making a single turbo kit that had a twin scroll design you'd be looking at some serious cash for it to work properly.

For example if I were to make a Twin Scroll Single Turbo kit for a Z i'd probably charge 12,000$ just because of the amount of work and labor involved.


Just to educate the guys above me, a twin scroll is a type of exhaust housing, it has 2 inlets on the turbine side of the turbo, which is made so you can seperate the cylinders that fire at the same time and pair them into each bank of the turbine. so say you have 1 and 3 and 2 and 4 firing at the same time. You'd basically build your runners and merge the 1 and 3 together in one bank of the turbine and do the same for 2 and 4. and run a wastegate off of each merge (because if you only run 1 wastegate you'd only be controlling one bank since the runners are paired and seperated)

The theory behind twin scroll turbines is that you have uninterrupted exhaust flow and they spool faster because of it.

So now with that you guys can see how hard it would be to merge the cylinders that fire together, into one (seperated from one another) into the turbo. That'd be alot of work!

 

lol,

I think he meant Ninja Scroll!

 

^ I would assume he is talking about a single turbo kit, because a twin turbo/twin scroll would certainly make no sense on a 6 cyl V layout.... Anyway,

Double the piping... Why?

This is a cost - Benefit thing.

Cost > Benefit in this case.

Edit: just re-read thread title, saw that he did indeed say twin scroll twin turbo, and formed opinion that OP is smoking crack.

 

Yeah my bad, i just noticed the twin turbo portion...

You wouldnt benefit from that haha..

 

Why not?

 

6/2=3

 

Intensefab, twinscroll turbos def spool up faster than single scroll turbos. Theirs no theory behind that.

 

Spoils of war, I was thinking you could divid up one of the runners from each manifold if not all of them if someone were to have a twin scroll twin turbo setup, or would that not work?

 

I wasnt saying they dont, but there's no way to benefit from a twin scroll twin turbo turbine on a twin 3 cylinder motor..

If you divide up one of the runners, whats the point of having a twin scroll turbine, because at that point you've defeated the purpose and now you've interrupted the exhaust flow

 

Take a ride in a Twin Turbo 350Z/G35 and then tell me you still want the turbos to spool a tiny bit faster at a MASSIVE cost increase. These cars with normal twins spool RIGHT NOW.

Furthermore, I don't even think this idea is possible on our motor setup since you can't "divide up" individual runners and expect the same amount of exhaust gas to go to each scroll.

This is a completely asinine idea.

 

Unless cylanders 1,3 and 5 fired at the same time and 2,4,and 6 did as well....(making this the most inefficent motor ever)

twin scroll turbos are actually JDM units on the STi and are very effective on flat 4 motors.

i think your best bet would be to stick with what is out there...as it works perfectly with a V6

 

I understand that twin scroll setups interrupt exhaust flow and what I said also does but would it not also help to spool up the turbos faster because the runners would be divided in to a twin scroll setup.

 

You would decrease overall efficiency and therefore negate an quicker spool potential...read post above.

 

Thank you for clearing that up im new to to this.

 

my friend has a full race gt30 turbo on his evo and hes at full boost before my greddy's at 3560 rpms. they are awesome turbos too bad they dont work on z's

i agree with noahs last line
