The capa kit uses one of their own home grown chips.
I dont know what changes they have made to the program, I think its mainly less timing and less fuel due to the bigger injectors they supplied, but i think they arent supplying chips anymore, instead they supply unichips.
I have 3 of they're chips here, but found it runs way better without any of them. (i mainly only used them for the firmer shifts, but as you all should know, theres a way around that now) I found with the chip in it was running inconsistent.
The race head, (bro works at engine reconditioning place) is an ex wanneroo race car head.
The guys that race them have the heads machined down way past the limit marks (so a good few mm) but this one required more machining to make it flat again, so they couldnt use it on the track anymore. (the rules are very strict) My bro ported it out more, and match ported the inlet manifold. Like i said it goes real well, dont know what compression its running or anything (he just slapped it on, typical young person style)
The only drama is that cause the head has been machined that much, a link needs to be taken out of the timing chain because the tensioner cant take up the slack, and its rattling (yes all new tensioners, guides and chain, only stock thing it the bottom end). If you want more details on it, let me know and i'll ask him. I dont know what valves and springs hes running in it. It has an EF/L cam in it.
Hes running an EBII diff (3.23) since he blew up the factory lsd, and 3 speed auto, which he blew up a few months ago also.
It still has noting on my EB :)
