yeah the space issue i reckon i could fix but as rodhog said, its about the money. the guy who had the turbos i wanted sold them yesterday the bastard!!
btw how much did u end up paying for the pair of t28's jules22?
In defence of what i said....i put this forward to anyone (not in an aggresive way or anything..) ..even if you remove and relocate the battery and fuse, which if standing front of the engine are located on the right side....you cant go any further right...because you would hit the radiator fan...
At the present time im running a 2.5 inch pipe of my turbo to the airfilter, this pipe is seriously less than 1.5cm away from touch the brace for the raditor fan....i have photos to prove this
The ONLY, and i mean ONLY thing you could do to improve the space to fit two turbo;s is remove the aircon and shift the whole turbo/manifold combo to the left...
The two turbo's back two years ago cost me $1000 for the pair...with the wastegates and manifold...
A proper Twin turbo setup could give you similar top end to say a Hi-flow T3
but you could expect alot more bottom end and mid range power.
Plus alot fatter and flatter torque curve.
It's not going to be worth it as you can get almost as close with a proper single turbo setup. Plus get more top-end.
The problem with Twin turbo set-ups is exhaust flow.
It just takes time and thought, plus added money.
Two GT-R T28's would be interesting. Being long storke motors the exhaust flow would be up heaps by 2000rpm but consdiering that a RB26 only is on fire after 4000rpm, I could see two T8's just like the factroy turbo and reaching peck at 3000rpm but it would give you another 3000rpm ot play with.
The best would be on a stroked Fe DOHC as then you could have another 1000rpm to paly with.
I reckon it would be too much hassle for the gains you would get.
All the extra exhaust manifolding etc would be too much personally for me to be bothered. There was a twin turbo civic in zoom recently with 2 wrx turbos and the additional manifold on that was 70kg. Im sure thats something you would rather do without also.
I think keep with whats tried and true on turbo 4's. A good single.
Wouldnt you also want something with a bit of a linear power curve also? It seems to be they want to break traction once a large 'hump' of power arrives.
i thought that a t3/t4 wouldnt be all that expensive?
they arent the best turbos in the world, but you could probably pull a t3 from an rb25det for fairly cheap (few hundred).. i think thats already large enough for an f2t.. (depending how much power your chasing!)
id suggest a t28bb from an s15. will cost you less than (or same as) a set of turbz from an rb26dett i assume.
