What should I get?
I'm in the planning stages of a special project, with the only limits being budget, and I have to use a N/A 2 rotor engine. I'm hoping to make about 200-250hp at the flywheel. I have a couple NOOB questions, first, what would be the most cost effectiveand "relatively reliable" powerplant to start with, a:
12A, 13B, or 13B REW (leaning away from that last one, due to cost, but if it'd be the most cost effective at producing 250hp, since that's pretty much where it is from the factory, then so be it) Second question, what's the difference in engine mounting locations and rotor case size between the three-transmission included? |
Also thinking of going forced induction, but if so, I'd be aiming for closer to the 450-flywheel hp mark... Anybody have any thoughts? Are these goals reasonable/attainable? I've already read about people making up to 600hp with a 2-rotor and big single turbo, but what if I want to keep it twin, so I can have dedicated true dual exhaust? Any thoughts for a rotary newb?
|
As for the engine mounting, I just wanna know how well I could use an old trashed junkyard 2-rotor engine for mock up purposes, prior to spending money on the real thing, like getting an engine from a Turbo II I've found, and then finding out how messed up it is. Possibly will be using it for the powerplant buildup/ or just using it for the mockup purposes, if it's too messed up. Will it work?

question what are you gonna be using for a shell??? any of the 13b motors are a good starting point for a turbo setup. The turbo II motor I think would be good if you can get it cheap.

Off topic but where abouts in Idaho are you located?

I actually used to live in Boise and am moving back in January. It's always good to find more rotor heads around the area for meets and what not. I'll be on Liberty between Franklin and Emerald.

200HP can be done with the engine remaining relatively manageable. A street port job, good exhaust and a decent tune can get you close to 200HP. 250 HP requires more radical porting such as a bridge. A good bridgeport setup will require a new intake manifold, standalone, etc.
Honestly it's a lot easier to start with the turbo 13B and just turn the boost up until you get your 200HP. This is easily done on the stock turbo while maintaining decent fuel economy (which sounds like it may not be a concern for you) and with a much superior torque curve. |

So, the Turbo II uses a 13B, right? So I could really get just about any 13B right? And has anybody created ITBs before? I'm going to search now, but if anybody wants to gimme a link... I'd use it.

13B's gome in two main flavors, a 6 port and a 4 port.
6 ports are stock n/a's, 4 ports are stock turbos Most big power street n/a's are done by running the 4 port. ITB's have been done before, but they are very costly. tweak-it is one supplier. |
