Default ls vtec rod bolts

ive pretty much read alot of threads on how to build a reliable ls vtec ...

but nonetheless im being CHEAP. the head went out on a car i just bought dirt cheap... i want to turn around and sell it quick i really dont care much for building an ls vtec ...

im basically slapping the head on and changing the oil pump on the car doing a water pump and timing belt change. my question is how long how hight can i rev the engine with stock ls rod bolts? how much at danger am i? im not planing on reving past a regualr gsr because im using a similar map...

1) How long

If built correctly, exactly 87,425 miles

2) How high

If built correctly, exactly 8172 RPM

3) How much danger

Medium to Medium Hot

Seriously, what type of questions are these? How can anyone answer them? What if you were going to spin a rod bearing anyway on the current motor as is but you switched to LSVTEC... does it then become LSVTEC's fault?

Build it how you see fit. Everyone has a different say in something so subjective.

yeah youre right ...motor has 152k on it. motor will only rev to 8k. i think im more concerned over a rodbolt breaking but your right, bearings are just as much risk...

so with that being said...guess theres no other way than the "right way".

8mm stock fitment ARP rod bolts......................$30-45 a set
Rod end machining to accept the bolts ................$60-80

These are figures of what I paid when I built mine. I mean, $150-200 total cost wont make or break anybody willing to spend the cash on a mild to extensive rebuild IMO. Atleast you'd sleep better a night knowing your motor can take the extra revs, which is where VTEC will make the added power anyway.

Given my opinion I wouldn't skimp on the bolts if your gonna keep the bottom end stock.

the issue isnt so much a rod bolt breaking as it is stretching, causing you to spin a rod bearing.
