TURBO build question

I'm currently considering going turbo on my h23a1 for now, then later on build a jdm h22a and turbo that.

But for the time being, I was hoping to get some specific questions answered:

1. If I piece together a turbo, the only thing I'd have to change when I switch to h22a would be the turbo manifold, correct?
All intercooler piping, wastegate, dumptube/downpipe?( I'm still learning), will all be the same?

2. Do you know of any ps/ac compatible turbo manifolds? I've heard of lovefab? and another that starts with an h, can't remember the name, but most I've seen aren't ac/ps compatible.I don't really want to get rid of it, and I know that lessens the options I have, but does anybody know of any that are currently being made?

Thanks for any and all input!

Re: TURBO build? Perhaps

If you get the same exact type of manifold then it might work all the same. More than likely you might have to redo the dumptube/downpipe and wastegate placement but nothing crazy. Oh and also don't forget a re-tune! almost forgot about that, but it should be common sense

I have the same head pattern on my f22b and the places i found for manifolds have logs, but not many ramhorn setups or anything like that. also It'd be very tough to find an ac compatible ramhorn, sidewinder,twinscroll etc. here are some log mani's that i found

treadstone:
H23 and F22a Turbo Manifold, Prelude, and Accord- TREADSTONE PERFORMANCE

I haven't asked treadstone if they can make this for an h23, but i think stainless would look nice but i don't know how long it would last also
F22b and F23A Turbo Manifold, Stainless- TREADSTONE PERFORMANCE

another log but from Spooling performance (I personally like the look and it appears to flow a bit better):
Spoolin Performance

and one other log from them, but a different setup:
Log Manifold Spoolin Performance

And the last one is from DRAG and i was thinking of contacting them for just the manifold cause it looks decent flowing, but then again IDK much about them, and their site almost looks too ebay'ish' if you know what I mean:
Drag Turbo Kits

There is another option of having a shop weld one up for you but thats your choice. Here is a pic of a guy on PP, and it looks like it is AC compatible but IDK. It's obviously the second pic:
Built H23 thread - Page 5 - Honda Prelude Forum : Honda Prelude Forums

One other thing i've thought of is rerouting the AC lines instead of running through the front of the engine. I haven't looked into it much as I'm still in the research stage for my build, but that is another possibility. With that you'd be able to possibly use a ramhorn or another setup. That's the route I'm most likely going to go since I'm planning on getting in the 350-400 range and the log i feel would be the limiting variable. Hope this helped with what you were looking for.

Re: TURBO build? Perhaps

yes all you would need to change is the manifold. spooling performance makes manifolds that let you keep ps

Re: TURBO build? Perhaps

Yes, that's what I've implanted in my head from the reading I've been doing and seraching about turbo these last fews days, is TUNING lol. TUning is the key.

W O W! Thank you very much for those links, I really appreciate it!

First link, looks like good quality, I may consider that one.

Second link, ehh I'm not so sure about that one, it looks good, but it must not be as durable, hence the cheaper price? I presume.

Third, I think this might be by far the best choice. I was reading and the best design is one in which the, shiet I forgot the name of it, that opening that you see coming out the top, is linked up to all four of the openings that go into the head, as opposed to the first link in which its directly linked to the first and second cylinder.
The only problem I see with these, is that they allow for only up to 38 mm waste gate.
I read that in order to help avoid boost spikes, that a 40 mm waste gate should be used.
But then again, I shouldn't worry too much and just use 38mm waste gate since I'm planning on switching the manifolds anyway. I see it as kind of a waste of money, but I just really want to have a turbo'd car lol.

Thanks again for your input!

How about ac? I think from the link he gave me, it allows for both.
BUt okay good, just the manifold? sweet! now to research some more on which exact turbo size. and what kind.

I've read that ball bearing is good, and more efficient, but that they don't tell you that its like not rebuildable or something like that? Or that replacing the cartridge, costs almost as much as buying the whole thing. I haven't looking much into journal bearing.

BUt I just need to figure out a turbo size for my ~230 whp goal on my h23, and about 250whp on the h22 for dd.

And of course the rest.

Also, for the ecu, is it possible to use a vtec ecu on the h23? so I wouldn't have to purchase another one when the time comes to put the h22 in?

ecu = p28 tuned on chrome, neptune or hondata s100,s200,s300

Re: TURBO build? Perhaps

Basically, any/all log style manifolds are ac/ps compatible. Anything fancier, like a tubular ram/mini-ram style, you gotta ditch one or both ac/ps. So just search for H23 log mani's.

THEORETICALLY, yes all you'll need to chance from H23 to H22 is the manifold. BUTTT.... like Dizzy said, your gonna hafta get the same style manifold that places the turbo and wastegate in the same EXACT location. That might not be as easy as it sounds, unless you find some manufacturer/fabricator that makes the same style manifolds, for both engines, then there would be a very good chance the turbo and wastegate flanges are in the same location.

I was thinking s300, would it work for both the h23 and h22? I know it's a vtec ecu, so idk if it's compatible with non-vtec?

Oh okay, that makes things a bit simpler.

That makes sense now. I just have to find one that does just that lol. If not I guess I'll end up spending more. But maybe someone would want to buy a manifold for their h23 turbo build :) lol.

yeah it is. You can turn off vtec if you want to with the s300 while you run the h23, then once you drop the h22 in and get it retuned turn the vtec back on and have fun!

DAmn, lol. Would I have to do that on my own? or does the tuner do that?

Re: TURBO build? Perhaps

When they are tuning it let them know that it is a h23 non-vtec and they should just disable it if they know what they are doing lol. I'm pretty sure it isn't hard to do. Just connect the s300 with a laptop and there should be a setting under there. If not maybe ask your tuner how and they could show you.

Re: TURBO build? Perhaps

Yeah I looked it up. It's as simple as a check mark lol. But Idk If I wanna do it on my own, though lol. Damn, well I guess I'm not gonna build an h22 no more. lol. Someone over on honda-tech just convinced me how to spend my money more efficiently, lol .

Re: TURBO build? Perhaps

yeah I mean the h22 is beast and all, but i like to be different. Thats why I'm going with my f22b dohc. It's already got iron sleeves and lower compresion. I'm buying another f22b and transmission to have on the side and build then dropping it in after pistons, rods etc.. They're pretty cheap too. There only a handful of people who have actually gone through with a turbo h23. Good luck with your build and keep us posted!

Re: TURBO build? Perhaps

Thanks I apprecite it. And yeah true that. I don't think I have to lower my compression though, for stock.

And yeah, that's my only worry lol. Not many people have done it from what I've seen. This is my first time even considering doing something major like this to my motor. It's my first car, and I don't have any experience under my belt. Only things I've done, and can say I've done myself is my suspension, full coilovers, and quick release set up, and a cold air intake. Lol I'll prolly start a new thread for when I do begin my build and start purchasing items.
