Im going to be running a 98 prelude h22a4 with 7 psi of boost. I will have a 255 lph fuel pump SAFC and 450 cc injectors. Should i get my ignition retarded or will i be ok for a while on just 7 psi? I plan on doing it eventually just not right when i put the turbo in, I'm going to drive it for a month or two. And when i do plan on doing it im going to buy a MSD.

 

7 psi will be ok. to retard timing efectively you need a timing gun to see how far to move the distributor. you can only move it by 2degres before the ecu brings it back to normal. byuing an msd setup should be the thing for you to buy right now. you'll need one with a turbo setup

Take your time and do it right. Get a Hondata or AEM ems and forget about all the band-aid solutions. 450's should work really nice with ~7psi and some REAL tuning.

 

I am taking my time. In the summer this is going to be a primary car. Will i be able to drive it with out timing retard on 7 psi for a couple months. if so. Like i said.. I am going to get a MSD just not right away.
Thanks for the comments so far... Keep 'em coming

 

I have been running mine with 7psi and no ignition retard for about 6 months. No problems at all. Although i have an H23 i dont think it would make a difference.
