Hey guys im back and ready to tune the car now. for those who don't know the set up here it is:

D16Y8

Turbonetic Turbo
Turbosmart wastegate
Vortech Blow off
Vortech FMU
Precision Turbo & Engine Front Mount Intercooler
Crane Hi6 Ignition
Magnaflow Cat-back exhaust
AEM Fuel Pressure regualtor

Anyhow i've spoken to a local guy who come highly recommeded for street tuning with Crome. I understand from all the feedback that i need to replace the FMU and get a better management system. Can I stick with a Chipped P28 street tuned with Crome and still retain my stock injectors and fuel pump? Im running about 6psi of boost. Or is it HIGHLY recomened that I get the injectors at the same time? And last do i need a better fuel pump? Or do i have to replace that to? thanks Any other input, suggestions is appreciated.

never save on the fuel system... it only ends up costing you more afterwards.

The thing is... if you're looking to custom tune the car w/ a chip, get bigger injectors (as I'm sure they're not big enough - although I have no idea what size they are) and u can ditch the shitty FMU completely and go back to your stock 1:1 regulator (assuming it's 3bar?)

and I'd defiantly recommend getting a better/bigger fuel pump.

As for other management... you could... but my friend tunes Honda/Acura's w/ Chrome and I've seen 500+WHP cars w/ the Honda ECU and his tune. Just something to think about.

your stock fuel pump will be ok and i would try and stay with the oem pump as long as possible. The reason i say this is because generally people would buy a walbro 225 pump. These pumps are awsome and are cheap when it comes to the world of fuel pumps, but reliablity can be an issue. It is not that i do not recommend walbor, but sometimes the pumps are not reliable in the sense that they will suddenly stop working, but who cares when you can go out and buy a new walbro and it is would still be cheaper then other pumps out there. As far as your injectors it really depends on what you plan on doing with the car. Are you planning to stay at 6psi or do you want higher? Your stock injectors can run out duty cycle real quick, so it may be a better idea to get new injectors. A common injector upgrade would be the eagle 450cc injectors found off the talon. This gives you alot of room for more power down the road and keep your duty cycle to a minimum. The other thing is you don;t want your duty cycle usually above 80% as this can wear out the injectors in a hurry due to the over working of them. I think 80% is a safe number, but others may argue this.
Crome is a good software for tuning obd1 and 2 hondas and have heard many success stories of it. You can tune it yourself if you have the proper equipment ie. computer interface and wide band , but i don't know if your up to that challenge yet. I am not sure how others tune, but i do fuel first and then play with timing.
goodluck

Thanks for the info guys, I've already talked to Zeeman and will most probubly get him to convert me from OBD 2 to OBD 1 with a chipped P28 tuned with crome, he also recomended that I get 440 injectors. The fuel pump is still in the air, with everything said and done its going to cost roughly $1000 if I get the fuel pump. I don't know if working on my boosted D16Y8 is worth it? I sometimes think I may be better of getting a GS-R or Type R motor. I've seen guys with good power running boosted D16's, just not sure about the reliability. Thanks for the input guys.

Although I don't agree with staying w/ a stock pump when going boost, unless u have a good pump in there from the factory (ie. old VW's running high pressure Bosch pumps because of mechanical injection), I do agree that you shouldn't get a Walbro... many have had success, while many have had failures.

IMO, upgrade to a OE Bosch pump, they're not much more then a Walbro, and they're great pumps. If you want to upgrade only once (if your considering more boost down the road), get the Bosch Motorsports "044" pump.

yeah i know the walbros are usually a hit and miss, but are on the cheaper side of aftermarket performance intake pumps. I can agree with you that bosch is prolly the better bet as there reliablitly can be granted. I mean oem pumps are reliabe no doubt so thats why i say stay oem as in boosted d's i have seen them do well. If he plans on raising the boost or looking for mroe power down the road i would say look into an aftermarket one for sure. Basically what i am saying is you can get away with an oem pump, but it may not be the best based on your goals/plans/what have you.

In terms of reliablty for a boosted d in stock form i would say they do alright. I mean for a daily driver i would stay around 6-12 lbs and you should be alright. Also it might be a good idea to play around with this motor and then later when you want more power or a change then look at engine options...
