Idea to make a T-25 work on my NA

Well.. I was gonna go with a stock TII turbo for my little turbo project.. But I lost one of my jobs and wont have the money unless I find another quickly.. But.. I had an idea to get that T-25 to work that you all talked me out of using last month. What do you think of a costom manifold, where one exhaust port goes directly into the turbo exhaust inlet, and the other bypasses it completly. Then they both mearge after the turbo outlet, down to a costom down and mid-pipe back to my N1 Cat back? Like I said in my other posts.. I'm not looking to make huge power.. I just want descent power (~200rwhp) with low end torque (at least 200ft/lbs). Since I already have the turbo, that'd cut costs by $300 and I think an exhaust shop could do all that for around $200 if not less.. Then I just need a small intercooler, fuel pump and 550cc/min secondaries and a few other things and I'm set. What do you all think?

hmmmm, i dunno man. one of the major bonuses of turboing a rotary is the awesome exhaust pulses that exist to spool the turbo up correctly. I haven't really ever thought of this before... it may work, but that manifold is gonna be one weird SOB.

200 ft/lbs. out of a rotary is going to be up toward 300 hp or so I think. Like Rice always says Torque=Talk :p

Plus the cost to have that weird *** manifold made is gonna offset the money you save by using the T25. Just sell that turbo.

Better yet, just route a hair dryer in the intake tract... that'll put LOTS of nice, high-temp low-pressure air in the system like a T25. You'll need to fit exhaust restrictors too...

(T25 is too small even for a 2-liter, and a 13B is a much larger, higher revving engine!)

THROUGH the TURBO AWAY!

It barely made enough power to work on the 2nd gen DSM's little engine.

That turbo is to small, by itself why dont you add another one and make a twin turbo? That will make arsome HP. The compressor housing is bigger than one of the turbos on my fd, and it is capable of making up to 16psi. I have one available for less than $200.
