just curiosity ...
has anyone tried this combo???
seems feasible if your a fabricator and can fab a manifold yourself and do a bit of plumbing.
just figguring that the stock T25 is good for 200 or so ponies...
so i fuggure on a budget you can easily hit 350 :)
and i mean the T25's are a dime a dozen since everyone is upgrading to the 16G's
any input is apreciated ( unless your sebba ... then just keep your opinion to yourself )
i have a T4 kit thats going on the 1G block that i will be building, but in the mean time i would love to play around a bit :P

you would have to make a really difficult custom manifold not to mention the nightmare of a IC piping and intercooler system. And they are junk turbos. There is no reason to do this. This has already been talked about before. A TT on a 4 cyl car is just not worth it.

yes... i agree that its among the worst turbo, but its also one the smaller ones as well...
i was figguring twin T25's would still allow quick spool times.
as far as the plumbing...
im looking at a Miller Portable Tig so i can fab my own stuff and 150A is plenty for aluminum and mild steel up to 3/16" thick.
the interesting part will be staggering the turbos to fit in the engine bay without hitting the rad AND have enough room for the downpipes and the rest of the plumbing.
first... need to find anoather T25 :)

all this time and work and your car will still only make no more than 260HP to the wheels. Its pointless. Lag time is not that big of a deal. I make 400+HP and lag untill 4k so what if my car lags for a half of a second because when it kicks in I still blow the doors off of people and now with 2 steps and NLTS lag in drag racing is a thing of the past. you can get a b16G has only a tiny bit more lag than your t25s and youll be able to make close to 100WHP more than the T25s would even allow.

ok ...
so in other words its not that much of a gain even with twins.
i was hopping about 350 due to the increase flow and the FMIC.
but then i will just get the 6botl bottom ready and for now just run a stock 1G head while i get the other one ready.
i wonder how long will the 7 Bolt hold together under 20Psi ith a T4E 60 Trim
