Here's the set-up

ZC D16A8 in a CRX with OBD0 ECU (PG7)

Bought new in '88 and my daily driver since. New paint, 17" kick-*** wheels, 12" brake, suspension, new suede (real) seats and interior, 1800 rms watt tunes, a fairly kiss-*** little car with the exception of power...

Not going to race competitively, just needs more "go" to back up the "show"

More or less a daily driver and would like to put back the A/C (there is an STI in the stable which I might end up selling if this turns out well)

Dont want to build up the bottom end at this point.

Planning on running 8-10 psi boost , whatever HP that turns out to be...


Here's the problem

Dont really want to switch to OBD1 and have to buy p28 ECU ($125), OBD1 Distributor ($200), wiring harness ($100), and Hondata upgrade ($500).


Here's the question, sorta..

I could either...

1. Get a Diaphram type FMU which will increase the fuel pressure (with walbro pump) 12 psi with each psi of boost, but the least amount of control but cheap

2. Use the Apex hack (with RC 370cc injectors, heard 440 too big) which will trick the current ECU as to how long to fire the injectors, (a reasonable compromise?) or

3. Switch to OBD1 and run the Hondata software which would give me the most amount of control, but much more (unnecesary?) $$$.

Is this accurate?

BTW, I'm planning

RH manifold (A/C compatable)
t3/t04e 48 a/r 54 trim
FMU still unknown

OR buying the greddy kit which I hear is a decent place to start..

Basically, probably like most of you, I just want to boost my little car safely and not spent MORE money then I <U>NEED </U>to..

I hope this post might clear up question for other newbs. thanks for your patience.

Go with #3, and use uberdata/crome (free program, just need to find a tuner)
