for just a basic kit running low psi, not a whole lot. a chipped ecu bigger injectors and in the case of the h22 the piston ring lands are a huge failure point. so after market pistons are a must there. besides that nothing. you can run 8-10 psi on a stock honda motor all day daily (depending on engine family). b-series will accept boost in stock trim quite nicely (given you have a complete name brand kit and also tuned properly). d-series are also the same but less psi levels are desired (bout 8 max).
the tune is the most important part. also a good leak down test will determine if the motor is acceptable for boost. I suggest staying away from any ebay kit, I recommend getting one from edelbrock, greddy, peak boost and so on. you could also go the home made kit, I suggest reading homemadeturbo.com for more information on how to do this. also clubcivic.com, honda-tech.com and so on are full of information on what kits work well and what kits well just plainly suck. don’t listen to the ******* homo that posted first. that **** is not required for low boost at all.
