I'm not really sure that NA is actually more reliable then the TII. I think only reason for less reliablity of TII is mainly due to fact that people will tend to drive TII more harder than a NA, and not keep up with normal maintance. I think a well maintained TII is just a reliable as NA. As far a modding a NA and TII it's all preference, if you are mainly concerned about speed go with TII, if you are mainly concerned about handling NA is just as good, if you want both then get a TII. It also depends if you want to mess with a turbo, any turbo car will be more complicated to work then a NA. TII have virtually no room to work with compared to NA(especially if your TII has ABS). It's much easier to work on my NA then my TII. But I like working on my TII because it offers much more challenge. Why not keep your NA as a daily driver and get a TII as a project car. My NA has few mods and I'm extremely happy with it but I not going to spend anymore money on it since potential for TII greatly out numbers that of NA.

i thought a stock na produced around 146hp??

This may not be absolutely true but from what ive personally seen n/a cars are usually better in manuevering, dipping, whatever you call it conditions while turbocharged cars are superior in the straight run. I have no idea why this si because i have never driven a turbo, but thats what ive seen.

You really need to drive one.
If you still think the turbo is just for "straight" driving, you really should learn how to drive.

Bottom line, NA's are easier to maintain and easier to drive.
IF YOU WANT MORE THAN 300HP AT THE WHEELS, the Turbo II is the only option.

Edit - If you want more than 300hp at the wheels in an engine that'll last more than 2,000 miles...

i think he meant to the wheels and 146 is to the flywheel

Just because you want to go turbo does not mean you actually need a TII. I have a complete turbo engine without the turbo,intake,wiring,and exhaust. The motor is ready to go I can sell it to you and you can add all the extras. This is the best way to build it at your own pace or (whenever your paycheck comes). so this way you can have a turbo without paying for the whole car.

Ok. How about mix and match existing RX7 parts so you can get them for cheap. TII transmission and a GTUs rear end with intake and exhaust would keep good pace with a S4 TII. Also you can thank that nice 3rd gear boost to the transmissions gearing. I have a TII trans in my N/A and the pull is very nice. But not boosted nice. Just nice.

is that 3rd gear boost, because of the turbo?? or because of the way the transmission transfers the power? i never did figure that out. because 4 banger, once i hit 3rd gear, i might as well pull over because it doesnt even feel like your movin. even tho my civic hits 130, it takes awhile.
