Runing a single tubro on V6 magna. would it work?

What do you guys and girls think?

i take it you mean on the V6 right?

sure it will work, turbos just run of exhaust gas (and heat) so as close and as evenly you can mount the turbo and have all the exhaust manifold runners meet up at 1 collector the better a single turbo conversion will work. But they dont have to be this way, as long as they all meet up it will work, a common modifcation for a Nissan 300ZX is a cross over pipe (this engine is a v6 configuration twin turbo, when converted to a single turbo, the turbo is put on one side as per normal, and the other head/manifold runners are then put into a collector and then plumbed under the engine into just before the turbine housing allong with the 3 other runners from that particular sides' head/manifold

Ive seen a few in TR magnas with the turbo being mounted over the top of the gearbox with all the runners coming up and and behind the heads, with the merge collector offset so the compressor housing is sitting facing the stock airbox and the turbine housing allows the dump pipe to meet the stock front pipe where it normally does from the firewall side manifold

yes... yes it will make your air conditioner colder.

um how could a single turbo work on a v6 ? thats alot oy cylinders for it to fill ?
maybe you will need 2 to make sure it actually does something

What about running a singles tubro on the front bank only?

yes it will work but not nealy as effectively as if you had the same turbo off all 6
you will need a tiny turbo to make any boost at anything under redline though it it really wouldn't be worth it

didnt that booya magna run single turbo?

it's been proven and can still make plenty of power

Single Turbos do work.

Look at Booya. 305kw & 655nm @ the wheels with a single garrett GT-40R running at 16psi on a 3.0L...

They do work.. just require some effort...

Single turbo is a viable option on a V6 magna. However I can't see a way to do it that doesn't involve relocating the throttle body to the drivers side end of the plennum chamber, and heres why; Due to space - the only place you could really locate a largish single turbo is above the gearbox, which limits the space you have to run pipes into the stock T/B location. You could probably manage to run a pipe from the turbo, directly into the T/B, but you would have no intercooling, which is not good. Try to plump the turbo compressor outlet into an intercooler (front mount), then back into the T/B in it's stock position, well I just can't see it happening. Relocate the T/B to the opposite end of the engine bay and it starts to look more feasible, you have a nice path for your intercooler piping (across the front bar from one side to the other).

Running a single turbo off just one bank of cylinders (half a twin turbo setup) really is a silly idea. Essentially you are only going to end up with half the power potential of a TT or proper single turbo setup, and it will cost more than half of either of these two setups because you will still need custom pipe work, intercooling, engine management.

Now lets talk about the interesting stuff - turbo selection. If I was in your shoes - I'd be seriously looking at getting one of the new "twin scroll" turbos, which utilize an exhaust housing with dual inlets to improve turbo responsiveness. I understand that Subaru use these turbos on their current gen cars - so it might be worth looking at getting a turbo off a new 6 cylinder liberty. It should be big enough that it won't run out of puff at peak, and still have the response of a TT setup.

i dont know how to link whole threads so this is just the first post.

i would seriously consider doing this if i were you (i did seriously consider it for my old KR)

http://www.aussiemagna.com/forums/showpost.php?p=681441&postcount=1

i went to the place that did magnatism's and the bloke said that it would produce definate results on a 6 cylinder.
heaps better than the 4.

it was going to cost me about 5 grand but that was because i didnt have anything whatsoever and had to buy all new stuff like turbo , FPR , fuel pump etc.

do a search for the whole thread , it is really interesting.

it is a remotely mounted turbo running off the exhaust pipe....

Two options here - like other people have stated, remote mount turbo, or split pulse (as used by Saab V6 Turbos) running off a single bank.

Split pulse is quite possible, but has a lot of quirks in the design phase - eg. you need a turbo with an exhaust wheel/housing to suit a 1.5/1.8 litre engine, but a compressor wheel + housing that supports a 3.0/3.5 Litre engine. Its very mix 'n' match, but you have more room for a turbo on the rear bank IIRC.

Cheers

that is a link to a site with pics of the gold BOOYA machine, also includes pics of the engine bay with single turbo conversion.

pure sarcasm there sorry

from what i can tell guys the OP was asking about single turbo setup running ONLY off the front bank
as i said it can be done and as heathyoung said it is a VERY mixed up turbo with two VASTLY different compressors to achieve any sort of results
the exhaust housing from a starlet GT and the compressor from a XR6T for example

this setup was used on the early V6 turbo 300zx's.

if you need a visual got down to a jap importer or anywhere that your can buy half cuts and take a look.

Hey BB, i don't see why it would be a problem to have the turbo on the passenger side along with the TB. There is heaps of room when you move the battery to the boot.

zOMG
16-01-2008, 11:38 AM
Don;t you want the turbo on the opposite side of the engine to the TB so you can run the intercooler piping across the front of the car to the engine. If you have both turbo and TB on the same side you will need to run the piping back on its self.

which wouldn't be much of a problem with the intercoolers that have both input and output on the same side

intercooling is for whimps :P


TZAMAN not really a boy now is he lol

he's running 10.5psi no cooler (yeah the sprintex cant be intercooled) but still making 20000kw or something like that

is the sprintex S/C a manifold mounted item?

No forced induction engine requires an intercooler BUT they defintely have a very useful purpose, hence why they are used.

yeah bolted to the underside of the inlet plenum, possibly could be intercooled, but only if you had a mate who owned a machine shop and you saved his life several times lol

i cant stress this enough guys, but if you are going to go the turbo route, seek advice first

although any turbo will work (some exceptions) but its not cylinders (referring to turbo specs on previous page : 4-6cylinders) that drive turbo chargers, its displacement. A good turbo for a 3L motor is a GT3071R non internal gate. Very responsive on a 3L motor whether thats 6,8 12 cylinders.

Considering turbo choice is the most important aspect to improving response, its a very expensive thing to get wrong.
