im about to build my head that will make power up to 9200 but start dropping and i want to rev atleast to 9500 so i end up in the highest rpm possible on the next gear

im leaving the block bone stock though.

will the stock block handle 9500 occassionally??? like once a week?

 

No.

Just remember what RPM stands for... Ruins Perfect Motors. On stock bottom end, I personally wouldn't turn past 9,000RPM. I've heard of stock R bottom ends turning to around 9,600RPM before catastrophic failure, but I would NOT push it.

I'd keep safe around 8,8000-9,000RPM until you get that bottom end built.

 

more input

 

I have a stock itr bottom end, stock itr head with toda valvesprings, Ti retainers, toda timing belt, toda cam gears and toda cams (spec C).
Bolt-ons include toda itb's, and hytech header.
Tuning is with crome pro and innovate wideband.

I usually rev it to 9200, but rev limiter is set at 9500 - I posted a vid around here somewhere if you want to see it.....

I mainly autox the car although I daily drove it for three years without issue. The rev limiter I used to hit regularly at 8600 but since i've raised it, i'm able to stay off it it more.
It doesn't seem to burn any oil more than maybe 1/4-1/2qt between changes - which is what it did when the motor was stock, although i am very conscious of proper and timely maintenance.

But Go-Fight-Kill is right - if you want reliability, then don't test the rev limiter too much! Unless you're making power this high, it doesn't make sense to rev.

umm, no. i have been running 9500 consistantly since 2001 on my stock bottom and stock head (toda cams/springs/ti retainers) with no issues.... this past weekend alone i hit the revlimiter no less then 18 times or so. so, if the motor is in good shape, i do not see why not.

 

my engine is very very healthy. i guess ill go for it.

if the block blows, ill go 2L hope not though

no, i just keep up with the maintainence on the car, so it works well.

 

I hear ya'.

I keep up my maintenence too, but man, a rod through the block hurts my brain. I'm just big on fail safe operation I guess. Good to hear turning a stock bottom end that deep has worked out for you.

Just last night this happened to a guy I raced. He had a built LS/VTEC (rods, psitons, rod bolts, race bearings, slight overbore etc.) I think he missed 5th gear.
He said he didn't.

 

What kinda power are you putting down Rodney? And what engine management?

nothing special, 194whp, tuned conservative (ie rich) J's Racing tuned the car with a jdm p30.
