My boy has a b20 vtec boosted and i keep telling him that when i had my stock b20 coupe it bounced off the rev limiter at 6200 and i keep telling him b20s are more TQ then HP and he shouldnt rev it really high and hes wondering on a all stock motor if he can go to 8k safely?

I say 7500 but he wants 8



Lets see what TR says

 

8k?!I wouldn't do it

 

What do you suggest?

After google'ing for a little it seems that 7k-7200 is good

 

I'd say 7200 without ARP rod bolts. 8k with

 

Prob gonna do 7200 then

 

I only rev to 7k in my B16 LMAO

I need me a motor with some torque!

From what I have been reading when i was considering a B20/V build, 7200 sounds like a very good spot to be safe.

 

Your just in your power band. Take that bitch to 8200 with no worries at all.

The b20 vtec should stay in the higher 6s

 

What Cams ?
Balanced rotating assembly ?

The only proper way to find out if it likes it is on a dyno

It may not make power/torque that high. No need to cont to spin the motor higher if the power isnt there.

$30 can answer this question easily

 

if u look on any dyno graph with a stock b20/v setup the power band falls off allmost the same as a h22 72-7300 any more is a waist

 

I would, but as soon as I get into that RPM range, and I let off the gas and pull that little lever next to my leg backwards, it makes a little grind

Actualy I have been taking her into 7.5k lately with no grinding, and I havn't put in the syncro mesh yet..
