porting hp estimate

wel i call a place called j.r.s rotary performance and talked to a guy that told me that if i got a street port/ exaust port and rotors from a 89-91 with a new eccentric shaft and flywheel. that i would be able to get over 200rwhp. does that sound about right? also if i could get that much power how hard would it be to do the porting my self if i got a template.

Power estimates are very difficult and really quite pointless if you ask me because they always differ.

As for porting, it is difficult and unless you have some spares sitting around I wouldn't attempt it. You can find out a ton about porting by going over to www.nopistons.com/forums/ and look at their porting thread.

I'm thinking(not a strong point mind you) the J R S Rotary Performance is Judge Ito's shop. He knows his stuff and has been doing it for years. If he builds and tunes the motor your in good shape.

Oh, that is Judge Ito's place!!?? Yah, pay him to do it and you will have a killer engine. He is one of the prime contributors to the porting thread on the other forum.

Give him a ring to see ho wmuch he charges. If you give him what you want out of the car I am sure he can help you obtain it.

He's way backed up to do that for your engine.

He will most likely tell you to find a place to do it. I know because he told me the same thing.
