i have a b16a2 si and i just blew the third cyl piston when i instaled my JR supercharger,
im getting a LS b18b2 short block and need your guys help. i want daily driver and reliablty, and i have a budget of 1200$ what kind of pistons, rods, bolts.ect. thanks
ohhh and JR super puts out about 5-7boost

Well homey, you aint gettin GREAT reliability with that kind of money. Cp pistons are good, lil pricey, and Im not sure if Golden eagle makes rods for an ls, but if they do, good choice. Otherwise go with crower, pretty sure they have them. ARP head studs are 100. Youre gonna need a vtec conversion kit from golden eagle if thats the way you plan to go...That 1200 is gonna go really quick, good luck

I could be wrong in this statement but I think the ls bottom ends are not balanced like they are in a b16a and b18c for the high revs those engines are made for plenty of people still run them but running it that high will not be good for its reliability unless you want to get a fully balanced bottom end and 1200 wont do that I dont believe.

ok well i can get way better prices then most people so forget the budget and just give me what you think i need. b18 pistons are fine, gsr bearings, apr rods, type R water pump, type R fuel pump whata yah think?
pr3 or p30 pistons or type R pistons?

yeah, bcivic is right... the ls engine was not intended for high revs. If you want to throw the tach needle into the stratosphere, get a gsr motor... they were designed to have the absolute p**s beat out of them, which is why the gsr was aimed at the 16-24 year old male audience.

Yea, that was the main thing that turned me away from the ls/vtec. You need to do it right, and pretty much sleeve it, pistons, rods, the whole 9 yards. It gets to be really expensive if you want reliability

w.e. you dont even know. only talk out of experience not word of mouth, i have five friends in CA that all did LS vtec rods bearsing and extra oil squarters and have had great performance!
GSR is a great idea but id rather rebuild a LS, it would be cheeper!
thanks anyway guys

If you have friends that have supposedly already done this then why are you asking us?
Ask them, who have, as you say, had great performance.

All I'm saying is an ls/vtec (even with $1200 worth of internals... which isn't much btw) revved to 8k rpm on a daily basis will blow way before a stock gsr. The ls is just flat-out not designed to rev as high as a b18c. It's like taking an h22 and revving it to 10k... the engine might hold up for a while, but it's just asking for trouble. And I agree with macbeth... if you know so many people who have actually done it, why on earth are you asking us about it and not them?

Lol. "You don't even know." That's a funny statement coming from someone who also doesn't even know. You ask a question, get an answer, and then write them off for them being wrong. Well if you didn't want an answer, why did you ask the question?
You blew your engine because you didn't tune the car. Plain and simple. You can certainly go and just build another engine but don't worry, you will blow it again unless you listen to me.:)

hahaha right, well its more of me saying hey im getting some stuff in my car got any other ideas, cuz have you ever tryed to LS/vtec and supercharge!? i didnt think so! so if you know anything that could be to my benafit post it dont waist my time say i dont know anything about my honda! i know well enough about prolly more then you know about your honda! if you got nothing good to say or you dont know from experence dont post!

Dude, if you're looking for info, then be respectful to the people on this forum who can provide it to you. If you're going to shoot down what people tell you because "you know" already, then don't be asking question...
From what I've heard, LS-V's rod ratio lends to a motor that doesn't like to rev as high, with equal reliability, as something like a GSR. You CAN rev one to 9,000, but you're going to need a lot of parts to do that safely. Take you're time...do some research, because judging by your JRSC experience, the "word of mouth" learning style isn't working out so well for you.

and_so_we_went... have you even seen what's under the hood of sov's civic? And you think you know more than him? He's more or less the forum's forced induction guru... he knows what he's talking about.
By the way, have fun blowing your new supercharged ls/vtec when you finish it, because I see no way you're going to do it correctly with that holier-than-thou attitude. Get off your f**king high horse, dude.

Why don't you go read the stickies I wrote, then come back to me when you have questions to ask.
You blew up a ~180whp supercharged B16. Believe me, this does not permeate your knowledge of Honda's very well.
Look, if you want to build a high revving LS Vtec you need to look at the rod and rod bolt strength. Otherwise, you will tear the bottom end to shreads. Pistons are whatever, you can use stock if you'd really like, the supercharger isn't going to make enough power to break them providing of course you listen and have the car tuned on a good engine management system.
Once you do rods you will still be limited to 8000rpms because you will have a stock head. In order to increase that you will need to put springs and retainers in the head. Then you are left with the fact that the stock cams and supercharger won't support power over 7600 anyway, so there is literally no point in revving any higher than 8000.
But hey, what do I know, I've never had a supercharger.:eek:
