I drive a 89 crx with a z6 swap. obd1 converted, bolt ons, fpr, and Xenocron chipped p28 ecu. I attend a tech school for autobody but they also have machine shop. My questions are,

- All machine work would be free, and no bottom end work. What is the maximum machine work i could have done and it still be useful without high cp pistons and so on? Intended to be a street car and 93 is available

- I will have 700-1000 to spend on cams, springs, etc. What setups have you guys experienced that make good power but completely streetable?

- Will the xenocron chip be a suitable tuning solution. They are sst reburnable eprom chips (with zif socket just for tuners ease), or should i invest in hondata s100-200?

Thanks in advance

 

1. I would do port & polish and a valve job, as far as modification of the head casting goes. If you wanted to mill the head to raise compression, i'm not sure of the tolerances.

2. not sure, no experience with aftermarket head internals

3. should be fine, get tuned on crome. hondata would be better of course though

 

port,polish, 5 angle valve job. stage 1 cam. adj cam gear. d16y8 intake manifold, port to match head, b16 throttle body. tune on chrome or hondata. you can also use d16y8 head gasket. its thinner and will raise compression. Dont shave the head down to much, just mill it to insure a flat smooth surface. you can also buy stock d16a9 pistons and put them in your block for higher compression
