I'm planning on putting a T3 Turbo onto my Prelude (H23a1), all the internals are still stock and I was wondering what a safe amount of boost would be. I've heard anywhere between 5 & 8, I'm trying to avoid any overkill yet get the most out of it right now. I've also been told be one person that I'll need to replace the stock injectors, and another that I wouldn't, anyone know which of these is correct?

Anywhere from 6-8 is good for daily driving. Even 10 every once and awhile. As for the injectors-yes you will have to get biggers ones as well as a full fuel manangement system, and you might want to look into upgrading the ignition, although the Prelude's ignition is great to start with. After that you'll need to head to a dyno and tune it. I'd recomend Hondata or AEM EMS.

Thanks for the info! I'll be sure to post my numbers in here when I get it all done.

you'll need a very large t3 for an H23 engine. IMO, there isnt a stock turbo that will work efficiently in this case unless you went with a holset or something.

how much does it cost to get a twin turbo honda accord fully loaded?

Why would you twin turbo an Accord? Near impossible unless youve got a V-6. If you have a 4 banger it won't be able to spool two turbos unless your reffering to two tiny ones which would be stupid, unless its just to be different. If you actually want to make power and have a usable powerband then one turbo is the way to go. But, judgung by your question, I don't think you know a thing about turbos so I would say keep her NA.
