im almost finished with my 91 rex ZC swap. i want an idea what it could run. thanks guys.

 

sohc or dohc?

 

ive seen best around 15.2...wouldnt expect much better then that

 

My ZC with IHE and my car slammed and 16" rims ran a 15.4 at like 90mph

 

dohc

 

how much are ZC engines... where did you buy yours?

 

i got my zc from nippon motors(good price 500$ , but shipping to CLE. 295$ )
i got a 15.9 @ 89.3 mph, but that was with the stock wheels, tires, clutch and hf tranny. I mean i passed the line in sec. gear...
so now after i'm done building my motor and with the zex kit, i hope to do much better...

 

Whats the redline on a DOHC ZC? Thanks

 

its 7200, you might see 7800 some places but it is 7200.

Damn nice time for being stuck with the HF tranny.. were you really going 90mph in 2nd gear?

 

what header can i use with my zc and where can i get one

 

expect mid 15's. for the header i believe you need an upper 86-89 integra with a 88-91 civic/crx downpipe, but i'm not completely sure.
