89 & 91 si
 

i was wounderen if someone can help me by tellin me the difference between the 89 si and the other series and also the 91 si crx what the best out come am gettin by gettin a 91 si or 89 si then the other series?

Ok punctuation is great on building a proper sentence. As for what I can decipher from that sentence, as far as I know there isn't too much different from the 88si and the 91si. I'm sure there are little things like maybe in the interior and stuff, but I'm not too too sure. I think they are close to the same car.

hmm im not to sure....but im sure the newer CRX 91 si would have a bit more parts available for it...so it would be easier to build up..and what exact differences are u looking at engine? body?

As near as I can tell, the 88-91 4th gen crxs all have basically the same body components, inside and out. Its the engine that differs. Ceratin years/styles have different intake manifolds and engine codes and such. I'd say, go for the newest you can get, and always go for the Si 1.6.
