Ls/Vtec----Experienced only please

[crv-tec]

So basically if I build an LSVTEC with the proper valves, springs, retainers, pistons and rods it should be fine revving up to about 7500?

[Greenblurr93]

SHOULD be.

[crv-tec]

But what is the rev limiter on the GS-R? Does it have a top speed limiter?

[civickiller]

why you only going to 7500? get b16 pistons, new arp rod bolts, vtec oil pump. thats pretty much it. that should handle the revs to 8k

[crv-tec]

Well right now I am still in the reseraching phase, but I've heard the stock LS bottom end isn't that great after 7000. I didn't think that taking it up to 8000 would be a good idea, but then again with the rods and pistons and all it should go up that high easier. Another question what compression ratio would be a good ratio to shoot for with the LSVTEC? Is it a good idea to run high compression on an all motor application like an ls vtec?

Let me rephrase this for you.

"If I build an LSVTEC with all the stock parts and a GE conversion kit it should be fine revving to 8000"

Past 8000 and I like to have some ARP rod bolts, because those are basically the weak link in an LS motor. I turned my B20/VTEC to 8500 daily with ARP rod bolts in a stock motor. With eagle rods and wiseco pistons I took it to 9000+ with regularity.

The B20 oil pump is the same as the GSR's, no need to swap it out.

Score! That will defintly make it easier. I don't think I'm gonna be doing the headwork, due to what needs to be done for the conversion, but I think I'm pretty sure I could put the bottom end together...

please make me look stupid... If I just want a simple LS/Vtec, all I need is some good rods, stronger pistons, good bolts fo the rods and not rev over 7500rpm?... Because I want to build one, but I heard they dont last too long.

Did you read anything I just said? I turned a stock B20 motor with ARP rod bolts to 8500 RPM's every single day for around 10K miles without any trouble. Stock block, stock crank, stock pistons, stock rods, ARP rod bolts. With eagle rods and wiseco pistons I turned 9000+ RPM's.
