Ok, im starting to piece together parts for my turbo build.

Looking for some recommendations. Mainly on the turbo.

What size/brand turbo should i go with?

My goals are 250-300hp on a stock block. Daily driver. Ill only be running prolly 7-8psi.

Here's what i have so far:

Turbo: (DUNNO)
Manifold: got it from motoxxxman (thanks a million) ***T3 flange***
Wastegate: Tial 38mm
Boost Controller: Hallman Manual B.C.
B.O.V: either 1. Greddy R.Z. or 2. Synapse.
Intercooler: Mishimoto Z-Line
Piping: cxracing kit off ebay.
Oil Feed/Drain Lines: (still hunting down)
Downpipe: custom fab unless i can find one online.
Exhaust: custom 3"

Tune: undecided where im going

Im pulling my engine as soon as its warm enough outside so i can "refresh" it a bit.

New OEM Honda headgasket, ARP headstuds (h22a4's fit the h22a1 right?), timing belt/water pump/etc.. I will probably eliminate the balance shafts but im not sure yet, if i dont, ill replace all seals and belts, etc.

With the motor out im goin to send the head to get some minor work done, new seals, valve job, PNP.

ill add more to this later. looking for some feedback on what i have lined up so far. let me know how im doing. i want to do this right the first time and not have to do it over.

thanks.

for the turbo, call turbokits.com and tell them i sent you. ask which turbo comes in the h22 prelude turbonetics kit, and tell them you'd like to buy just the turbo. you can get the journal bearing one or the ball-bearing one for a small amount more. both have a 1 year warranty, and are perfect for your goals.

you also need an ecu of course. you know who to go to for that :)

for injectors, i'd go with 550cc or 650cc. 450 is too small, and 750 is pointlessly too big

good choice on the boost controller by the way. the hallman is the only manual boost controller i trust. i've installed and used at least 50 of them.
you really dont need it though unless you want to occasionally raise the boost higher than what the wg spring is rated for

what kind of turbo is in the turbonetics kit? and do you plan on more hp later down the line? invest in a garrett gt3076r its good for up to 500 wheel but is also good for under 300 around 8psi. it sounds sooooooooooooo cool too haha but thats beyond the point.

57 trim t04e compressor, .63 a/r stage III t3 turbine. pretty similar to a gt3076 actually

hmmm interesting. I was looking into buying one of those kits orginally but i asked around before hand and not to many people were happy with them. granted he may only be buying the turbo and not the kit as a whole but who makes the turbo? or is turbonetics the maker/seller?

lol thats probably the only excuse i've ever heard of for why someone's block is taking so long to get built that i actually agree with haha
i forget what its called officially, but i hope you have a rubber drivetrain damper in that thing. i forget if they have one stock or not.
its the thing in the tranny that street bikes have but dirtbikes dont

You forgot about fuel. Judging from your other parts listing, this will be a moderate build. I'd go with 680cc Injectors, Walbro 190lph Fuel Pump and an AFPR. Can you tune preludes on Crome? I tinkered with one on a turbo teggy and it seemed like a nice program.

actually no, 190lph is too small. he needs the 255HP. and no he does not need an afpr.
honestly, 99% of the time an afpr is completely useless except for looks

and yes, you can tune preludes on crome. i've done more than plenty myself, all with perfect results

Well I don't know what his build is and just assumed the turbo he was going with. Obviously if it's more of a 35R or larger, more fuel will probably be needed. A 190 is good for a decent amount of power. Assumed it wasn't going to be a crazy amount since it's on a stock motor. Also, what makes you think AFPRs are completely useless? I've never personally used one, skipped out on it and just went with fuel pump and injectors. But I've heard good things from name brands, not the cheap ebay knock-offs.

adjustable fuel pressure regulators serve only one purpose: to adjust the fuel pressure. and adjusting the fuel pressure only serves two purposes: 1) richening or leaning the mixture by using higher or lower pressures, which is pointless when you have a tuneable ecu that can adjust that independantly at all manifold pressures and rpms. 2) setting the base fuel pressure to a pressure that the injectors work best at, but the stock fuel pressure in a prelude is the same pressure that almost all common aftermarket fuel injectors are already supposed to use anyway.

so yes, an afpr is useless in a turbo build
