So I am trying to decide between an H swap and a boosted Z6. This is my DD and I will be making long (17hours both ways) trips once or twice a year. I also belong to an autocross club and do that every weekend. So, my question is what do you guys think is a better engine to go with? I only want 250whp out of the engine. I like the D cause its cheap and easy to drop in, but I like the H cause it would be N/A (more reliable?). Cons, the D will be boosted and im not sure if its going to be able to handle all that driving and abuse. As for the H, good lord Iv heard soooo many bad things about this swap, cable tranny is junk, too heavy, breaks mounts, too much torque, cant lower your car cause of the oil pan scraping, axle rubbing.

edit: i know about the H2B but i really dont want my hood sticking 2 inches in the air

what do you think?

H22 would be fun just to hear vtak. But that gets boring and a blow off valve is more impressive. Boost the D, get a great tune and have a sweet DD. And you said "only 250 whp". All I have to say to that is - Lol.

h22 would take the 17 hr trip better. the boosted d will be faster. thats just my .02

uhhgg, I didnt wanna have to say this, but i think its the second time someones got on me for saying "only 250hp". I drive (most of the time anyway:D) a Mustang GT about once a week in the summers for the radio station i work for. Having said that, not only do i hate mustangs, i dont like the power it has, too much for me.

also, for autocross, wouldnt N/A be better? before the turbo kicks in the D is just a 120hp engine right?

unless you get a small turbo the spools instantly like a t25

I heard (as in not 100%)on honda-techthat the H engine weighs only 50lbs more. Thats nothing. And I think if you got good mounts like Hasports, they would not break, infact I have never heard that one before...

if i may paraphrase a rapper.... drop a D in dat B*itch

a low spooling T25 would be great for autocross, but wouldnt that be killed on your DD MPG? I say boost the D, BOV and D-series ftw!

Fixed mate.

Boosted D > H Swap

Cheaper and more fun.

Sorry I was wrong it was the B16 that the H weighs 50lbs more then. But the link is still wrong, caseu the guy on honda-tech did a weigh in with both motors and said the B is lighter by 50lbs.

Grow a wang. I'm not out to get you riceburner, and I'm sorry you don't know how to defend your groundless statements. Besides, I was only asking in case you knew something I didn't.

The guy that only weighed the shortblocks? That doesn't take a lot of the rest of the motor into account. Check out this link: http://www.honda-tech.com/zerothread?id=879297 The B16 is more than 50lbs lighter than the B18 anyway.

Ok, let's swing back on topic.

To the OP, a H22 won't be anymore reliable than a boosted D if you get it properly tuned (which is about ~500-600 bucks from most professional tuners), assuming the D is in good condition to begin with. The boosted D will be better on gas as well.

I hate when people are begining to grow a mustache, it looks like they have dirt on their upper lip. I call it the 'dirt stache.'

i call it a..

Crustache = crusty mustache

Ok thanks, I was leaning toward the D for some time now, but just want to be sure its what I need. So a good tune and itl be fully reliable then?

Why are you talking? Take your own dirt face talk somewhere else.

Lmfao, its called a sanchez. and A Turbo D would be way better. however the engine will not effiecantly handle 250 whp without some internals. I beleive it only is recomended 220 whp.

if you drive a mustang and feel that is too much hp for you, then 250 whp in a civic will scare you.

i say just get a b16 or a b18. you obviously want a realiable engine with more power than what yoiu have. and this would put you in the middle. more power than stock and good reliablity. and parts are cheap and everywhereif you look for them.

Do a compression/leak down test on the motor before you do anything, and then make sure all maintenance is up to date. It's a lot better to take care of anything it needs while you have it apart. The only things I can think of that aren't in the service manual would bearound 80-90kthe throw out and input shaft bearings may need to be replaced. Other than that follow the manufacturer's manual to a T. If you need any advice on mods holla.

lol! thats funny "dirt face talk" hahaah oh man.

if you don't like the power in a mustange GT, realize that a 250 hp civic is a GT killer.

What are you asking? Why he thinks the H will take the trip better, or why the boosted D will be faster?

Maybe if you worded your questions more clearly, instead of trying to set people up, you'd get clearer responses

The boosted D being faster is kind ofcommon sense. But I see your point. I should have specified I was refering to the H business.

im sorry to go off topic, i just got a little laugh from the douch bag turbo d that has 17 posts and runs up in here like he owns shi*. Anyways, turbo-d and if your autocrossing, im not sure you want to take hair pin turns with that H sitting up front.

Well said...

are you in such a bad mood cause you have to drive that thing everyday? If you are then I agree.

Attacking veteran members of the forum that have the respect of MANY is not going to make you look like a badass. The only thing you are going to gain from your immature attacks are people disrespecting you. Chill out dude.

I know man, but why sould I have to take crap from this chump? Is that how it works? If i ever get 1000 posts I can then go diss noobs?

The D series is going to need forged rods/pistons to handle 250 whp. I would stay with the D series, but do it right. A Z6 with a built bottom end would handle 250 whp no problem, but getting it tuned to like 225whp would be more than you need/want, and its less strain on the motor. As long as the D series engine is built and tuned properly it will be much better than the H swap. I was getting 40+MPG on my 19T Greddy boosted Z6........and it wasnt even tuned properly.......

1. Its not about posts, its about respect
2. Again, calling out a long time memeber on here and asking them why they are talking=not good idea
3.If your in Atlanta, lets meet up and race for pinks, we can see how much it sucks to drive my car

Stop being a prick the kid just came on here to get some questions answered. Its douche bags like you that give honda forums bad names. Join date and number of posts is irrelevant. and 3.If your in Atlanta, lets meet up and race for pinks, is possibly the dumbest most ricey thing ive ever heard. Stop the E-Thuggin yo. I think a boosted B series is the most suitable motor for you.

"E-thugging yo" beats my statement by a long shot. And i said the exact same thing you just did about post numbers. If you had bothered to read preivous posts, youll see he came with the attitude, not me. And, i also gave a legit answer in the question he was asking.So, anything else to make yourself look like an ass, or are you done?

Come on quit flamin, your jacking the thread. In all reality the h will be more reliable (other than normal engine problems any car has) cause of course you'll probably be using a stock ecu which will do away with tuning problems and turbos don't last forever. With the autocross a t25 will spool fast and the extra weight of an h22 will have to be made up in suspension work.. The t25 civic it starts boosting at 2500. the problem with that is with freeway travel your about 2500 to 3000 rpms. I believe riceburner has a t3 turbo that spools at 3500. I'd ask him about his set up. You'll also have to consider when doing autocross is traction. Both set ups will have hella traction problems. My first gear is a waste cause I can't even get full boost (redline + spinning tires lol) Whatever you choose keep us posted.

Not trying to thread jack, im done. He had a attitude with a member, i said somthing about it and yet at same time answered his question with a legit answer. Whatever, its over. Good luck with build on whatever you decide to do.

Wow.How is this insulting? "Why are you talking? Take your own dirt face talk somewhere else." That's just funny. If that was at all insulting it was lightheartedly at worst. You came in this thread withmore of an attitude than anyone. Sbowers had it right. Imo, respect for Turbo D > you.

come on you guys, t34 and Kedawei you guys are both vets,drop it and move on,i think this guys really lookin for answers and that ^ post is the only helpful on this page (other than Petes), and it was made by a 1st gear membe nonetheless

And IMO i can understand the reliability he was talking about, alot can go wrong with turboing an engine,just look atRemmy the other day blowing a coupler on his charge pipe, and tuning can go wrong as well, many things can go wrong and you really need to know what your doing, andeven if you do know what youre doing its a risk,just look at Tony n Pete's turboed Ds

Ok guys, well I thank the dudes that gave me a hand here, its gunna help me make up my mind for sure. Im getting over $2,000 back from the tax man, and well $1,000 is going into the bank, the other 1k will go to the engine. Im sure I can pick up a Z6 for less then half that and the rest I can put into it. So I think thats where I will start. Im going to look into a t25 right away here. Thanks for all the info. Later.

What engine do you have now? I boosted my d15b7. Its my first turbo so i don't care if i blow the b7. I'm tryin to find either a jdm d15b or a z6 to build up then swap it in and give it a real tune (running greddy emanage) it works but i'd reccommend getting a fuel pressure guage cause i'm running rich but thats way better than lean.

T25 would be the way to go for your budget and goals imo. Try this for a manifold as well: http://homemadeturbo.com/tech_projects/HF_manifold/index.html

Wow, thanks for the link, good info. You'll need an adapter plate but you could probably find on tuner toys for cheap.

Aside from all this flaming and whatnot, I'll put it on the table IMO. I know your thinking mannnn Turbo so much work! Dropping the H would be easier! That may be true but think of all the things you will learn after you have completed your tubo set up. You will no more than you would if you just payed some shop to drop in a H. If you decided to go N/A i would go B series anyway. Good luck on your build and I hope everything works out.
