OK hears the deal. i have a civic hatch with a stock h224, i also have a full greddy turbo kit from my old single cam laying around. now would it be safe for me to run 7lb of boost not opening up the motor to put new head gasket and add a block guard? not really being cheap but a always believed that honda's always seem to run best un opened. like i said i have a full greddy kit truly only need the manifold...

First.EG

you should be good. get it tuned and down rev past stock limit

Wrona

a block guard is junk 7 psi on what turbo... just cause its a greddy doesn't tell us the size

injectors and fuel pump? do u have a tuner u are going to take it to?

not opening the motor?? i don't even understand what this means opening the motor up doesn't mean sh*t unless ur a crappy mechanic...

I would not put a Greddy kit sized for a D or B series on an H-motor. You'll probably have it spooled up at idle. H-series is obviously bigger. You'll need bigger everything to go on this engine. Don't think for one second you can move kits around like you can on a D and B series and only swap out a manifold.

Un-opened is poor slang for stock. Your belief is totally without merit.

Generally speaking h22's are plenty strong. There's been plenty of people who've made 400+whp on stock blocks with no real issues. Moving this to the FI forum.

As I understand it, it's all about the sleeves.

t28 Garrett
440 injectors already have the 255 wel-bro
i have a tuner who knows what he is doing
not opening it because if dose not make sense to open the motor and not just do a full rebuild well it out and apart..
call me a crappy machanic or not, at 18 years old i built a 11 second hatch by my self thanks though

^^ i did the same thing with my rex.. i could only work on it on my lunch breaks.. and after the shop closed... so me and my buddy would go up there at like 11 and come home at like 3.. haha but mine never reached 11's though you have a pic??

No one's talking about a CRX.
Use the T28. It'll spool quick. That's about all I can tell you.

apexi_rsx

t28 is a small turbo for over a 2.0L motor. id recommend alil bigger turbo. this turbo is only good for 300-350hp.

ffeog1

truthfully only looking for 300hp so id be happy with that

Actually, if its from a D-series kit, you have the TD04H-15G using a hybrid Garrett T25 flanged and internally gated system, good to only about 35lbs/min. That won' make more than about 220whp or so on the H-series engine, at best. The wastegate that came with the kit is about 6-7psi at most and will require a boost controller or modification to work properly. Otherwise, you'll be blowing a lot of useless hot air soon.

Honestly, its best to look to a completely different exhaust manifold, turbo, downpipe and wastegate to start off with here. Even on the stock engine.

When was any of this part of a Greddy kit on a D-series?

TheShodan

iTrader: (14)

It never was. But from what I see, the OP is looking at the turbine housing of the D-series kit that he had. As I stated, the GReddy kit for the D-series contained a HYBRID Garrett/Mitsubishi turbocharger (Mitsu compressor wheel, compressor housing, backplate), while the turbine was from a Garrett (Garrett turbine housing, T25 flanging system and turbine wheel.)

Yeah. I'm running the turbo and manifold from that kit.

Wrona

and what happened to that hatch i never called u a shitty mechanic

but when u turbo ur car u have to put a new headgaset along with ARP headstuds or ur gonna have headlift

extralargenog

Wrong. Its all about the ringlands.

Do a setof studs and a HG... Be nice with timing...

How.much power are h22s safe for with studs and a gasket... Assuming you have a decent size turbo and a good manofold?

extralargenog

600 + has been made stock block more than once...

BUT with a safe tune on a healthy motor (Studs and a gasket ) Ive seen more than a few LAST at around 400+ Wheel (Done so personaly) The good manifold (an efficient one) and IMO a T4 hotside will help keep reversion and egt issues from popping up...
Only issues Ive seen with doing so were log manifolds on turbos too small running **** tons of boost to get there.

Hs really dont like restrictive hotsides at all. If a t3 housing Id want nothing smaller than a .82. In a T4 Nothing smaller than a .68.

400 is totally doable on a well tuned healthy motor ... WIth some longetivity if you take care of the engine :O)

CO_RaceFab

Awsome... We are currently working on one. I have tuned countless 450ish hp stock b series hopefully i can pull this one off lol.

What about a T3/T4 turbo? I am thinking of doing a turbo on my Stock h22a4.

KdrewsBB6

yeah does anyone have an opinion on what size t3/t4 turbo would be good on an h22. looking to get ~ 350hp on stock block with arp studs and cometic head gasket.

unuselectus

Waking this thread up. I'm trying to get a nice turbo that spools very quickly. I don't need 350hp. I really don't even need 300. I just want a quick spool at low rpms.

I've been readying a lot of threads. What's the smallest t3/t4 that would help me
axhieve this?
