Engine/Tranny Swap Question

Im getting a B18c1 swap for my 95 civic, and I wanted to get the s80 transmission from the integra type r, but I just wanted to know if I had to get matching years on the tranny and engine, and would I be able to add a turbo to an h22? My friends getting a crx and swapping in an h22, so I was just wondering.

From my understanding, you can match up any tranny that came from a b-series engine to any other b-series engine. Even if that's not entirely true, an s80 will match up with the b18c. Now for the H22 turbo, The H22 has high compression at 10.x depending on whether or not it's JDM. It also has weak cylinder walls. These two factors prevent you from running high boost without first building the internals. If you want to run boost higher than 6-8 pounds, I'd suggest resleeving and getting 9.x:1 compression pistons.

Other than some MAJOR cutting and fabricating; there's NO way your friend can fit an H22 and a turbo in it. My buddy has a h22a and turbo in his 95 Civic 4dr and there was bairly enough room in that thing; so I'd say no way for turbo'd H22 in the crx.

Ok, one more question, im getting a 94-00 swap, so would my compression be to high to get turbo? From what I read its only 10.0:1

I don't mean to be a prick or anything but you've asked the same questions over and over again and always get the same answers. So one more time here is what people are going to tell you... if you want turbo with little problems and a b-series then get an LS. Otherwise you'll need to build the bottom end of the GS-R, H22a, ITR; whatever the hell you decide to go with. The GSR specifically is roughly around (USDM) 10.1:1 and (JDM)10.6:1; so yes that is to high for you to turbo safely. Same problems with doing the H22 turbo without building the bottom end. But hey if you don't mind spending $$$ and being pissed off when you blow your shit up and have to replace you're new engine then go right ahead.

Well I looked up hardheaded in google and some guy named catstevens came up, ive checked in the mirror a few times and uh they dont match, any way only reason I ask the same queston so much is beacause I get different answers from different people, some poeple here say its too high some say its not so which is it? I dunno if you guys go to honda tech but they had a forum about GSR vs Type R engines, and ya they say you can add turbo safely, and I know you guys arent saying I cant, its just you guys are saying LS is overall better to turbo than GSR, but if thats the case why do people even buy gsr swaps when they can get ITR or type r for all motor?

Cause the GSR is less expensive than the ITR engine, and there are a lot more of them out there (usdm, jdm, etc variations). And you can build the motors up whether a person decides they want to turbo it or all motor it; not that you can't with the type r but why spend an extra grand+ for the ITR when you can buy a GSR and do the same things to it for less $.

Ya, but im not like gunna get all into it and wat not, im just buying things and adding it on, nothin too hard, cuz this is my first car and im just kinda experimenting, but I wanted to konw if id be able to fit type r parts on an LS/Vtec engine. But holon, I just read something, what engine do I have? Its a 1995 civic, thats like 5g rite? So dont I have more hp than the LS/Vtec, so would my engine be faster than the LS/Vtec, if they were both built up, or is it becuase of the acura parts that I can trade into the LS that would mke it faster?v O ya and when you guys say that its too high to be boosted you mean turbo and superchargers right? Last thing, I went to totaljdm.com, and the LS/Vtec(97-01 integra right?) and it doesnt come with transmission, now would I have to use my old transmission or do I gatta buy another one, cuz I dunno where to go to buy anothe transmission.

don't know about the ITR parts fitting in the LS/vtec. But the engine you have now isn't going to be as fast as a LS/vtec with a similar build up. The LS engine alone already has more torque and hp than your current motor. Your car now prob has either 106 or 125hp depending on the model. But where do you see the LS/Vtec for sale on totaljdm.com??? All I see are the stock engines on there. But you'll need another tranny from a b-series, your d-series won't fit on it. I'd go with a b16, ITR, or even a gsr tranny for the LS/vtec. But again if you're going to have to turn the LS into an LS/vtec with a vtec head; that pretty much gets rid of you saying you don't want to do something hard. It's got to be built correctly or you'll just blow the thing up. Another thing you could do (I'm just throwing a random idea out here) you could build up a d16 and turbo that; on turbod16.com there are people doing 250-300+whp with a SOHC.

Alright, thanks, and about the totaljdm.com I only see the integra B18b(97-01) so I dont even know if thats it, and alseo I found http://www.japanstarmotor.com/honda.html and its got the LS b18b with tranny, but then again I was prolly doin the v-tec thing, so how would I build up the bottom like you guys said in order for the GS-R to be able to handle turbo? So would I just have to go to a local shop around here and ask them how much it would be for them to build me up an LS/Vtec engine? So all engines with higher compression than 10.0:1 are intentionally for all motor?

that motor on totaljdm.com is just an LS motor not the LS/vtec. But in all honesty I would skip the LS/vtec and jsut get the GSR like you originally said in the begining of the post. All you'd have to do is to bring it to a local machine shop for them to put in the pistons, rods, and whatever else you buy. If you're going to have a shop do the LS/vtec make sure you ask them if they've done it before; I personally wouldn't trust just any place to automatically know everything involved with the head swap. The higher compression aren't definently just for all motor (i know you know that already) but it'd be a lot safer to run lower compressions with turbo. And with lower compression theoretically you'd be able to boost more; of course if your internals can handle it.
The link for the motor didn't work for me, not even main page. But if you're going to do the LS/vtec the LS tranny is going to have too long of gears, you'd definently benefit from one of the other trannies I mentioned before.

So when you told me juss now that I should just go with the GSR, what route should I take? All motor or Turbo? If you had to choose.

Depends on $ you're willing to spend and what your hp goals are. If they're both built up; the turbo setup will more than likely be able to produce far more hp in the long run. I personally would probably turbo it, but that's just my opinion.

Ok, you prolly alreay answered this but what steps would I have to take to turbo the gsr?
CivicSpoon

You'd have to take your bottom end to a machine shop and have them put in new low comp pistons, forged rods, head studs, and if you're going to be boosting quite a bit; sleeves too. I don't know anything about head work don't even know if you'd need it to tell ya the truth; but I've heard of people burning their valve seals. Maybe get some cams, valves, springs, p&p, aftermarket intake manifold, fuel rail, injectors, etc; if you want full potential and have the loot. Other than that I don't know maybe someone else can tell you more than I can.

alrite thanks, ok i know your prolly sick of me askin but heres another question, what would be too high of compression? Because I found a usdm gsr with 10.1, and if I were to buy the ls/vtec or get it all made up, would I have to buy my parts differently, because i buy most of my parts off the internet, and they catagorize them by make/model/year. Ok and since I dont know like anything at all I was wondering wats the whole goal of having to add a turbo to a high compression engine? Is it just to add more mods to make it so the engine can handle it or is it just to tone it down a little so that it wont go way over? Plz like map it out for me. And wats 95 civic ex vtec's engine code?

i have a question, ive been doing some research, and with the budget i have, it seems that the 1.6L DOHC NONE VTEC!!!!! is the best choice, i found out that my 91 hb is easy to do that swap in it, but if i want to go with b16, or b18, i gotta get special mounts, and there is also some wiring and welding, cutting ect that i have to do, anyways.... what is ur opinion on this?
