I have a LS/Vtec swap in my car, what is a good redline and what's a good rpm to shift gears?

Setup:
LS/Vtec
Crower cams
Crower Cam Gears

Thanks

 

stock valve springs and retainers? 7200!

 

stock bottom end.... 7200

 

Have anybody go any higher without any problems? Let's say 8000?

It's got Ported gasket Matched head. Chipped P28 ecu.

i got a chipped p28 ecu from ih8ricerz, rev limit at 9200.... in first, if im realllllly going for it ill shift at about 8600, just to keep it deep into vtec, then into 3rd and into 4th i shift right around 8200. i have arp head studs, rod bolts, different pistons, valve springs, retainers,

 

oh, and brand new rod bearings too!

 

Cause the shop that did my installation said I can shift at 8500 with my stock retainers and stuffs. But if I shift at let's say 7200 then it's gonna drop to NONE Vtec zone and takes couple of secs to get back to Vtec.

 

i took mine to 8200 with no problems

couple secs? u must be slow.

 

i'd want to get that crank balanced a little w/ the rotating assembly, shot peen the rods and use arp rod bolts. a girdle and pcv breather aren't a bad idea either... thats a pretty cheap way to strengthen things up for 8000rpm

 

I would say to shift at 7,800 RPM but you dont have stock B-series cams, which make max power at 7,800. Your stock block REALLY shouldn't go past 7100 but shifting there would be foolish.

 

Get your crank balanced and go to a dyno. You'll see where you should shift by looking at the power curve.

 

My buddy has been building LS/VTEC's for years and years. He tuned mine with stock bottom end for 7600 redline with a 4800 vtec changeover. I am also running hondata p72.. buttttttttttttt if your runnning stock bottom, he told me no higher then 7600, 8000 is pushing it unless you have GSR OIL/WATER pumps.

 

hahahaha

i 2nd that

8200 should be perfect...just dont bonce it!

 

7500-8000
stock ls bottom, stock gsr top. absolutely no problems for over a year, about 15k miles
