The Defined Autoworks 20B conversion kit-
#52
...and the results were???
How much higher does this sit than a stock 13B? Quarter inch? Any clearance issues with the transmission in the stock tunnel? Can a front strut tower bar or some variant still be run?
Nice kit and excellent job BTW. Just curious to know how this kit and position tips the weight distribution on the car. Keep up the great work.

I have a engineer working with a very nice CAD program, and is doing stress analysis on them right now. They definitely are very stout, and will give the performance numbers once that is completed. A street-port 20B with a well made custom intake, and well made header can get over 350rwhp.

With stock twins and stock engine, its very debatable. Most seem to agree 400ish rwhp with stock twins is at the upper limit of power.

Ooooooo i always thought a 20b was a 2litre rotary engine, that needed moe care and probably at least 91 octane too =O
im curious though... do different brands of gas, at 91 octane level, give u guys different mileages??

If you are keeping it stock with the twin turbo's, or upgraded to a single turbo, then yes 91+ is definitely needed. Its only when custom converted to n/a can they run 87-89 octane. They are 2 liters as well. I never tried 87 to see the difference in mileage, it would be so small anyway.

The higher the octane rating, the more it resists detonation do to high cylinder pressure and temperature (i.e. boost). If you are not boosting the engine then 87 octane is safe to use and actually recommended on rotary engines because the slower flame travel speed of the low octane fuel works for the rotarys longer path that the rotor travels. The only reason to use high octane is to fight detonation and not for high HP. If you are not have problems with detonation then use the lowest octane you can. All boosted engine need high octane because the turbo heats the air more and pressurizes it to the point the detonation on low octane.

Any updates (pictures) of the modified intake manifold? Also I gather you are removing a chunk of the oil pan for fitment, any idea how much oil space you are losing? (1 quart, 1/2 quart).
Looks great though.
Thanks,
Jonathan

>>Q:What do I need to send in to be modified?
A: The Steering rack, P/S bracket, 20B oil pan, Alternator tensioner, 20B intake manifold.
Do we still need to send in the steering rack if it has been converted to a full manual system? I am talking a hard conversion, not the 'loop the lines' conversion. My steering rack no longer has the lines/fittings a stokc one has.

I can answer that for you Damian. It would be a "Yes!" I had mine fully converted as well and then sent off directly to Logan to further modify.

Any pictures of the modified LIM or complete engine in and out of a car yet and are you ready to start shipping part at this time? I really like what I've seen so far and just need a little more info and pictures.
