Ok, so im about a quarter of the way through my build i have a 91 crx hf (with a boosted dohc zc now ) getting a b18a1 built for it. I’ll list what i have
Eagle Crank (i know stock is good for like 800hp, but i got a good deal on it)
Eagle H beam rods
9.2 SRP pistons (.020 over)
ACL race bearings
Fidanza 7lb flywheel
ARP Head Studs
Obd0-Obd1 conversion
Type R oil pump
Type R water pump/timing kit.
I think thats all. Anyways im skipping the whole sleeving part due to thats another 1300 or so. and im not doing a block guard too many horror stories, that and my block is already bored for my pistons. Like i said I plan on putting around 500hp to the ground. I’ll be using hondata s300 and it will be tuned. Also i have meth/water injection that will be used in this setup. I guess my question is does anyone see a problem with my sleeves being able to hold a bit over 500hp at the crank? If so why? I have searched this on here and many other forums, and i know there are a few freak motors that are hold insane amounts of power with a completly stock block. Thanks in advance guys.
I dont have the specifics of my brothers 2nd build,
but he got it tuned, pushing 16 psi @ 274, and cracked a sleeve. I think it was at stock bore. if not it was close. When the sleeve cracked it messed up his pistons, and a bunch of other stuff. He ended up spending well over 6000 dollars to have it redone, and sleeve the block.
see the thing i would consider here is. Is it worth it to save the 1300 now,
push your block halfway to your goal and having something fail and screwing up a lot of what you put your money into…
then you have to tear everything apart.
buy new parts (that you have already bought once)
then pay to sleeve the block the second time around.
rebuild the motor,
retune the motor (not cheap)
people will say this and that. “yeah i made 900 hp on stock sleeves” but trust me if you are planning on pushing anything over 250 HP I would suggest sleeving it first. save yourself a lot of trouble by just do it right the first time.
three things that i would put most of my attention to
the rods you use… dont skimp here
sleeving,
and the tune.
I would recommend biting the bullet and having it sleeved. If you crack the block and damaged any of the other stuff you bought you will be in the hole a lot deeper. The stock sleeves might handle the boost, but for how long?
I can’t remember who’s signature I saw this on but here goes.
if 400hp is all an ls can take without sleeving than i wouldnt have bought any parts besides a head gasket studs and pistons rings. With a good tune i know these can handle power, hell my stock d series(zc) is gettin 11.5lbs of boost i know its a small turbo but im damn sure its around 200hp and people say that zc’s are weak with boost(it pulls hard on slightly modded wrxs, and ls1’s). and im sorry your bro had a bad block that cracked at just over 250hp. if i was only gonna aim for 300hp i would of kept it stock and just got it tuned. And my goal is to be somewhere in the 10sec range. This car will be a weekend warrior and track car. I just think you guys dont have any faith in these motors. When i had that motor in my 91 hatch i had the basics done I/H/E and i’d walk on ep3’s and such. hmmm…just a few more months and it’ll be done, i’ll keep you updated on it.
here is a link to honda-tech notice these are all stock bottom ends, hell the h22’s get double the power than what people say they can ever handle. http://www.honda-tech.com/zerothread?id=1478127
We had faith in these motors.
First we had faith with the rods, only pushing like 7 psi (i think) a rod went and put a huge hole through the block.
Block number 2… we had faith in the sleeves. With upgraded rods and pistons, injectors, a better tune and much more… We went to pushed it one day and BOOM, smoke EVERYWHERE! conveniently and hour away from home at an Integra meet.
So saving some money and putting some faith in the block ended up costing him:
2 destroyed blocks,
2 sets of pistons and rods,
along with a boatload of other parts,
price of having to tow it twice,
the embarrassment in front of all our peers,
a smile on a domestics guy’s face,
loss of his temporary daily driver (the first time it was his dd)(the second time, his dd blew a head gasket so the integra was going to be his dd til the other car was fixed.)
money to retune
many nights sleeping on the couch (because of the grief it caused his marriage to sink all this money into it and boom, it doesn’t even run.)
and much more
dude… you do what you want. All i can do is share my experience with you in hopes you learn from our mistakes, so you dont have to follow in our foolish and expensive footsteps.
For me, I wouldn’t go over 250 without sleeving. Good luck with your build, either way I hope it works out for you.
IMO, I would look into sleeving if you’re lookng at around 300-350"WHP". I was making 270whp on my 100% stock B16 that I ragged on everyday for a year without any problems. But I now have a sleeved motor because I wanted to make alot more power. If you’re looking to mainly track the car, then depending how often you track it. It may nt be worth sleeving even with big power. I sleeved for the extra security as my car is a daily driver.
BTW, the DOHC ZC, or USDM Integra D16 is a very strong motor. Practically the LS version of the D series.

sounds like he was putting faith in a bad tuner. the ones that know what they’re doing don’t seem to have any problem being well into the 4xx range on stock sleeves.
I will admit that ZEROLIFT in Cincinnati can suck on my fucking balls
they screwed him soooo bad its not even funny.
But we learned and went to TPR in Cincinnati and learned what a good tuner shop is like.
I am sorry but I have not heard of anyone calling the zc a weak motor with boost. Those things can handle a bunch of boost. Concerning your build I am sure you can put 500 down but it might only last a week if your lucky. Go ask some of the guys over at homemadeturbo, some of them are real dicks but they are truthful about turbos.
Agreed… HMT guys know their shit and I dont mind them being dicks, but its the blatant racism and immaturity that keeps me from going back any more than I have to.
) getting a b18a1 built for it. I’ll list what i have
