You sure they make press fit aftermarket rods? as far as I know all forged rods were made with a sliding pin design, but then again I may be wrong.

Re: B18a1 pistons STOCK vs. FoRGED
are you serious
its a honda, ALL b and d-series seem to go in the same order...
pistons<rods<sleeves
pistons being the weakest, b series and d series ringlands seem to suck, people DO make high hp out of stock blocks, but why not just save a few hundred more dollars, and go with some srp pistons, tunertoys rods, and arp headstuds and call it a day
if nothing else, your STUPID if u put aftermarket rods in with stock pistons, if ANYTHING slap some srp's on top of the stock rods, a good low compression pistons too, like 8.5:1 and then run your 20psi, give yourself a detonation cushion iwth the compression to protect the stock rods... and dont rev too high, b18a/b dont like being revved out much...

Re: B18a1 pistons STOCK vs. FoRGED
this thread is retarded, if you do rods, then you need to do pistons as well, what a waste to do one and not the other, and there is no ------- way that stock LS pistons will handle 400-450 whp for more than a few days, I dont care if your the god of tuning, with cylinder pressures that high the ring lands are DONE in no time flat.... and I didnt see you post anything about the head your using, but it better be built, because a stock LS head wont make 450 whp even if you throw 25 psi at it from that t3/t4, it needs at least cams. and an intake mani., p+p job, and springs and retainers wouldnt hurt... bottom line if you dont build a motor right, its gonna blow up if you try to push it, and a stock LS head will not make 450 whp....best of luck to ya

The only reason the LS-V is unreliable is because of situations like this - PENNY PINCHING and downright IGNORANCE. People put HG's on backwards, don't do the dowels right, run a cheap oil supply setup, etc etc. With a little homework, experience, CONSCIOUS THOUGHT, and a bit more money, and LS-V can be as reliable as a GSR buildup.
Stock pistons with forged rods will need machining done to accept a circlip/spiral-lock/etc to keep the floating pin in place. AFAIK press-fit forged rods don't exist from TT, let alone ANy company. Its a safe bet that if they do, the extra cost is the same as forged pistons. Getting the pistons machined and getting the locks will eat away at your savings over forged, and you'll have nothing to show for it.
FYI There was a 560whp bone-stock B16 about a year or two ago. After several dynos and 1/4mile passes, it finally cracked the ringlands. Rods (stock!) and bearings were fine. I think the same deal happened to a similar stock H22. The only real motor that didn't follow this rule was D16Z6 from Epic tuning. The ringlands survived, but thats because ALL four rods bent slightly. This effectivly reduced the CR and automaticly made the conservative timing FAR MORE conservative.
CLIFFS: Your a complete moron if you do a B18 build w/o forged pistons. **ANY** problems you encounter will >100% offset your $$ savings.

One of my friends is running 100% stock ls (except for head studs and headgasket) ebay t3/t4 topmount mani at 18#s of boost and sometimes hits boost cut at 21psi
Makes close to 350whp and runs 12.2 in 1/4 on DRs
All on pump gas
Another friends is running an LS/VTEC at 18 psi with a GT30R. Also 100% factory except head studs and he used a 10 year old head gasket for this
Made 361whp on a dyno dynamics
Ran 11.5 in 1/4 on 20" slicks
Now has pistons & rod combo, also put a new Head Gasket in
525whp
Both cars were done by the same tuner. Over 500 hondas tuned in the past 7 years. So what im trying to say is it's all up to the tune. Run e85 if you can to achieve more power safely or race gas
