hey everyone, im new to imports, so i dont know too much about them. anyway, i own a 1991 DA Teg and im installing a B16a2 and a turbo. i have a set of integra LS pistons i plan to use for my turbo build to lower CR. with posibly H-beam rods and ARP rod bolts

so here is my question, how much boost could i put to the LS pistons and hbeams with arp bolts?

thanks for the help i appreciate it

Don't ask another thing on this thread here until you've done these two and taken a few days to figure it out. There are going to be a LOT of people telling you to search via google and the search thread.. know the basics and more..

Good luck.. And to let you know.. i'm going to pretty much be the nicest guy for this response here. The others... not so much

Good luck.. happy reading.

i appreciate the advice....cant hate the newb for being a newb tho lol. anyway, i treid goodle search and nothing came up. i will try the search on here

Get turbo pistons

Correct me if I'm wrong you can't use ls pistons and a after market rod. Also, psi/lbs doesn't translate to whp. Like Shodan said search and read the FAQ. If you searched for what you think you can do....well it may because you can't do it.

It's ok, I've decided to just use my pr3 rods with pr4 pistons. Just gonnA run 10-12lbs

And that yields what??

02SSLAYER

I dont know what you mean exactly....I've been told I can run 10-12 safely with my current setup and that is fine with me. I don't wana get to deep into this project

10-12 PSI doesn't mean ****. Without knowing what turbo you're using those numbers are irrelevant. Read the FAQs and you would know that.

Even if he did know the turbo, each vehicle is different
10psi on my setup creates 345whp

There is really no point in swapping one cast piston for another. Even if the compression ratio is lower, it's still a stock cast piston. Dropping 1 point in compression isn't going to make the build that much safer. It will give the tuner a little bit more room for error, but truly any competent tuner should be able to make the tune safe no matter the compression.

So far in my experience don't go past 300whp dd! 260-280maybe

I'm using ls pistons over b16 pistons for lower CR. TURBO IS ihi, alive is RHV5. Honestly I was getting a little out of my budget so Im just making motor and turbo work...no aftermarket turbo cams no h beams etc...the ls pistons will lower my CR enough to run 10 lbs Hoping to make about 250whp good enough

jimbo slice

There is no need to use Ls pistons to lower compression.

But I guess you are stuck on that train of thought.. Btw I've made 420 whp on a stock b16 block on e85 using a HX35

I just don't understand a few things with this build

Switching out the stock pistons with another stock piston to some how lower compression. Just leave it bone stock...
Psi/pounds doesn't mean anything, have a whp goal
Have you searched the interweb about turbo b16 stock motor setups?

I've decided to only read half the replies.
here is my advise to you $700 will get you a good piston and rod combo= eagles rods and arias pistons, then you need bearings multiple brands = personal preference. but since you have to ask such question tells me me you don't know what you are doing, regardless if you drive imports or domestics its the same concept when it comes to building and selecting parts. you can boost your stock motor and make power, but I can recommend this list for you.

golden eagle sleeved block
manley turbo tough rods/or pauter
Arias pistons
Arp studs
golden eagle head gasket
clevite bearings
and thats only for the block

hey guys, ill clear something up. i bought a used b16a2...turned out only the head was useable. so i was on the search for a cheap b16 shortblock, that shortblock came with the LS pistons which is why im using LS pistons. i do like them due to lower CR, runs better with boost. id rather not boost a high CR motor. anyway, im pretty new to boosted setups and the honda world. i understand that the concept is the same, but there are different companies associated with chevy and honda. just wanted to know if the PR3 rods and PR4 pistons are safe for 10-12 lbs. i was wanting to run boost cams to help the turbo out...but my budget is quickly boiling over lol

kyden

stop saying it runs better with boost. that is not the case. low compression is the way of the old days.

grumblemarc

iTrader: (4)

Uninformed statement.
And goddammit stop asking if 10-12lbs is safe! Power breaks ****. Not PSI. It just highlights your ignorance on the subject.

You're saying you're new to boosted setups, but just knows that the lower compression is better for boost.



Get humble.... quick. Stop saying what you think you know and that you're confident in your thought process, because right now, you're already at a bad start conceptually. If you want help, there's nothing wrong with asking for what you need to do.. but this unnecessary puffing of the chest is a waste of time.

1) The lower compression idea is not automatically "better for boost", get that out of your head right now when getting away from the push-rods you're used to. As stated, whether or not you actually swapped the LS pistons in there or not, going down less than a point in CR has no bearing on your ability to have the car properly tuned and able to run over 300-350whp, because that's the maximum the B-series parts can handle.

2) Stop thinking in "PSI". this 10-12psi as a way determining what power to run is archaic. You need to have a particular power goal, then pick the correct turbocharger to associate yourself with those power goals and response characteristics. "T3/T4" doesn't help either, so please don't go to that level of thinking. It won't work.

3) Have a plan of attack instead of just blindly asking. Verification is one thing, blindly asking for spoonfed feedback, completely different, and will get you the worse responses, and your inquires won't be taken seriously.

Just tellin' ya how it works on this forum.. It may not be the best unofficial policy, but it does work.

made 400 on a stock b17, with a shodan garrett 32b turbo.
Ls pistons in a b16 will not benefit you anymore then the stock block came with.

Ya so most of you guys are ******* douche bags. If u don't have something positive to add them don't add anything. Lower compression is in fact better for boost. Than say 12.0:1 I'm new to this ya but I seem to know more about it than most of you idiots. I can probly get better answers on ls1tech. I know plenty about motors. My American v8 would run bus lengths on most of you. Peace out this forum sucks *****...ill build my acura better without all your snide comments.

Er. Lower compression is only "better" for boost if your tuner doesn't know his ****. It allows for more wiggle room. So in fact, lower compression is not better for boost, but better for mediocre tuners as it give them a cushion if their tunes are off.

Knows everything but still has to ask questions.

Peace out.
