its a t4 sc61 going on a fully built+sleeved h22 bored out to 89mm (2.3Lvtec) 9:1 Compression with stock head and rev limiter at 8000, wondering if spool up times on the street or the track will be very bad/long?

anything is streetable..

ones opinion of streetable varies.

i can certainly drive with that turbo on the street, but some people would rather not.

what rpm do you think it'd fully spool at? i mean ill give up some laggy-ness for some good top end power


***what else can i do to help with the spool up time. its bored out to 89MM "h23vtec" i have a lightweight flywheel, what else?

oh yeh, PT61 on H22 = the bull's-eye

 

have fun floating a valve. why spend all that money then not put a couple hundred more in for stronger valve springs and retainers. especially if you are goin to 8k

i was considering springs and retainers, most likely will only take it up to 7600

 

It shouldn't be that bad since you have a 2.3l. How much power you want to make? My friend has a h22 built and made 524whp on a t3/60-1 @26lbs.

my goals are around 500whp, think i can do that @20psi?

def. worth the investment. when i actually drove my car on my last setup, i only took it out to 7300 but that was all stock internals. what compression are you thinking about running. i'm starting to build up my h22 with a t3/t4 60-1, .82ar. and i'm still researching, let me know what yougo with

9:1 compression, i already have this all done. awaiting manifold and couple of other parts.

crap, i forgot to mention precisionh23a doesnt have vtec, so i guess that dyno doesnt really tell me much, how much more power do you think ill make with vtec?

is it ball bearing? (if you have it listed, sorry. I missed it)

I am currently trying out my setup on my B20 before i drop the fully built LS in just to see how my setup spools and makes power. Well lets just say i thought mine was too big but I'm finding now it is plenty and is perfect in my eyes. Full boost at 4k. at a roll boost is pretty much instant. and at 6psi i almost trapped 109 but ran 13.5 because the clutch wouldnt hold and the tires wouldnt grip. (car was 2335lbs)

A/R70; A/R84 hotside, 64.5 trim ballbearing

your engine should deff. spool that thing up. Good Luck

 

that is a sick turbo, will go nicely with your set up

 

You said T4 SC61, do you know what turbine wheel you have? I can see that it's a .58 A/R turbine housing...

A friend of mine had an SC61 P trim with a .58 A/R on his DSM. At 2.0 liters with 9:1 compression, I didn't think it was bad at all. Full boost came in around 5K, but the exhaust side of the turbo was big enough to keep from choking off the motor without boost, so daily driving, it made as much power down low as any other NA 4 cylinder. Didn't bother me one bit.

I bet yours will hit full boost quite a bit earlier, with the extra .3 liters over him. Should be loads of fun.

i think there is a very good chance you will hit the 500whp mark with 20psi. thats a nice set up and turbo

 

PM Kwuaymaikrup. He has the same turbocharger but with a .81 A/R turbine housing. His powerband on pump gas and race gas shows it's streetable. And you should see 500whp at or before 20lbs of boost.

what motor did he have? i think that might be a little to big

you can never go too big jk

 

With an H22, you definetly want to go T4. My friend is using the Innovative T4 turbo and it is very streetable

 

t4+H22=

 

look what this guy had to say....

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by PreIudeSI &raquo;</TD></TR><TR><TD CLASS="quote">that turbo is not going to be streetable. The proof is in that dyno posted. A good measure of where you hit peak boost is where the torque peaks. In this case, around 5800 to 6000 rpm. that is not streetable. Streetable power bands are broad, the hp curve is linear (not exponential as is the one posted) and torque curves are flat. A streetable power band has maximum area under the curves and is not peaky (as posted). </TD></TR></TABLE>

Have any of you ever driven on a laggy turbo in normal driving conditions?</TD></TR></TABLE>

 

hmmmm, H22 fully spools a PT67 GTQ before 6k.

and redlines by 7500 sounds like an awesome power band. The bigger T4 ideal for a drag set up or somewhere that you are going to be redlining constantly. It will be streetable i'll give you that, but its going to be almost pointless if you are planning on doing any sudden spurts. If you want something that can pull hard on the streets look into a bigger t3 housing

try 8800, son...and the car makes 630whp...so even at 4000rpm its making more than most people.

I will let him tell you if you ask him Nothing no one else on Honda Tech has.
