Would A Twin Turbo Parallel Setup Work On An Rb?

[Gameboy]

Im planning on rebuilding an rb engine for my Silvia (actually, first time touching the internals of an engine) and am thinking of going twin turbo parallel. Reason I am concidering, I use to own a 300zx and I just loved how it delivered the power. It felt like driving a non turbo with heaps of power. Now, has anyone done this to an RB engine?

Can I use a Y pipe to combine both turbo's to go into a normal intercooler? or would I need a 2 in 1 out intercooler?

Parallel? as in 3 cylinders feeding a turbo each......like every GTR ever produced from the R32 on?

[Trozzle]

I'm thinking he's just used the wrong term and actually means "in series"

[zebra]

but that doesnt make the 300zx thing make sense...

as they were just feed each turbo from each bank.

For (I assume) a 25, I wouldn't bother. Extra plumbing etc would be a nightmare

He definitely means just like a GTR.

And yes, the opinion given above is the correct one. Single is better. Much easier to fit in, much easier to pipe, and, depending on power target, with modern turbo designs, no worse lag.

Twin turbo sounds like a cool thing, but the reality is not as good as the theory.

wait, what?? doesnt the GTR use sequential?

EDIT: ok all these years I thought the GTR's were sequential...makes things easier for me then lmao

nope

lol, might want to do a bit more research before you rebuild an RB

wise words

[Gameboy]

lol yeah.. nah have stuffed around tons with RB engines just never a GTR.

[Ben C34]

Well good luck with it all. If you thought gtrs were sequential you are in trouble.....

Lol

Short manifolds and two integral waste gates , works but nightmare to work on unless you're assembling it and then dropping the body over it .

Disagree. Driven many singles and twins before I built mine. Twins up to -5s are much nicer to drive than any single setup I have driven. It sounds good in theory because it is good in practice

On an RB25? It does not make sense to go to all the effort and pain to do it to a car that doesn't come that way to start with.

nah gonna do a 25/30.

[GTSBoy]

Wasn't responding to you, was responding to XGTRX.

[XGTRX]

Ooohh sorry. Thought he meant 26. My bad. Ignore my comments. Apologies again.

nah gonna do a 25/30.

if going into a silvia, and you want twins, go 26/30.

the slightly extra on the head, will more then be saved by the fab work which the 25 would need.

if you keep the 25, just get a GOOD single.

theres alot out yhere now that can make very decent power with good response.
