I am putting a gsr into a del sol and was wondering if the 88-91 throttle for a crx is long enough to work

 

If you're talking about the throttle cable it's best to use the GSR cable and bracket that mounts on the firewall. The GSR cable has a bracket on the throttle body instead of the intake manifold and it comes in to meet the throttle body from the other side, different from most others. You can usually get the stock cable to work too, but if you want it right and like stock then get the GSR cable.

 

I reused my DX throttle cable...All seems well...

 

I have a 92 VX hatch with a 99 B18C1 swap. At first I used the stock throttle cable but it would stick every now and then. I bought a 94-01 GSR throttle cable and the firewall bracket - looks like it came that way from the factory. Not sure about all models but my car even had the stay-tab hole and threaded bolt hole to mount the GSR bracket on the firewall.
