good choice my friend, stick with the wankle...



as for power loss, you'll just keep pulling straws till you do a compression check. find out if any seals have blown, and if you have good compression on the rotors, then go from there.

New here to this board, but....



Compression is for sure where you need to look. My guess is that it's to late though.



The only way I'd do a piston engine in a TII is to do it right....



My LS1 Powered '87 TII



That there is more than $5,000 though.



I've had the car since almost new, and have had A LOT of fun back in the day. However, this latest combo is great! I drive it every day. Over 28mpg on the highway. 1/4 mile, 11.78 at 118 with sticky tires.



I loved my rotary engine, and still have TWO other rotary FC's. BUT, I just wanted to shed a little light. NO FLAME WARS!

If you're doing a non-rotary swap, then either the LS1 or the GN engine are the way to go, IMO. That '87 is a prime example of a nicely done conversion.

wow... i've been to that site before. Nice job. Yeah money is tight, i was planning on trying to build a 327 or a 350, but i slowly came the the realization of the price and my lack of money, so i know its still expensive, but the rotary is looking better and better.

they lose power for the same reasons piston engines lose power. its either the compression is low, the exhaust is clogged, fuel filter? air filter? ignition? some of the details or different, but there not really that big of a difference between a piston and a rotary, when you are diagnosing something.

Not lookin' for a debate on piston vs. rotary, but I disagree. (I'm keepin' my 13B for now, until inspired otherwise.) I think they are alot different when it come to durability. (But I know you're right about the similarity of diagnosing problems) I have seen literally hundreds of piston engine vehicle with 200K+ on the original, never rebuilt engine. They still run strong. My dad's S-10 and my Ranger are 2 prime examples...over 215K on both, never rebuilt, still run strong. If U see a 200K+ rotary, chances are that it's been rebuilt once, twice, or even 3 times before. (or it runs like $#!^) He's right, they lose power over time. Simply said, they lose compression and have to be rebuilt. YES, piston engines lose it as well, but not near as bad...and NOT to the point that they need rebuilt every 75K.

I say leave it a rotary.

You must be talking about 3rd gens when you say rebuilt every 75,000. 1st and 2nd gen NAs run forever if they are taken care of. Even with a TII, they'll get to around 120k - 150k before their engine usually goes. There is a Rotary shop here that has a regular customer with a 1st gen with over 300k on the original engine

300K miles.. damn. That's awesome..
