First off, the Honda ECU(even "primative" OBD-0) are over-engineered and very robust for their era. Don't mistake the older ECU technology from being crap. Myself, and a growing number of others chip Honda ECU's to run boost on a daily basis. Granted our grassroots movement doesn't have the shine and bling of something like Hondata, AEM, Zdyne or the like...But it's free to those who want to learn and are capable. Now as for the Rising rate regulator and bigger injector junk....[soap box]Thats just a poor mans way to 1/2 ass supply fuel for boost. It does work but it's a retarded way of adding extra fuel, thats been around since the very early days of F/I. It shouldn't be applied to today's EFI setups....AT ALL.[/soap box] Jacking the distr
ibutor back to retard timing also isn't a very reliable way to account for timing under boost. 6-8 psi of poorly tuned boost can do the same amount of damage as 20psi. Adding more air, your gotta add the right amount of fuel, and compensate the timing properly or you're just asking the engine to grenade on you. An OBD-0 ECU can be chipped with a conservative prog to run boost and ulitize larger injectors....for just about any engine you want for normally under $100. I'm not saying i'll do it, but i'm just saying it can be done.

Swap frist, turbo later if not satisfied. Turboing the SOHC, unless you got with a junk yard turbo setup and some grassroots DIY ECU tuning you're prolly looking at 2000~3000 to get it done right. You'll still only be marginally faster than most B18 swaps with the hassle of owning a turbo Honda, and all the little problems that entails. If this is your daily driver, I would HIGHLY recommend an LS/GSR swap over turbo, just from a sheer reliability stand point.
