Default Stock bottom end on B20/vtec

Will it be okay to run a stock bottom end on a B20/vtec. The reason why I question is because right now with my B20 I only rev to about 6000 rpm and if I get a B16 head Im gonna wanna take it to 8000 rpm. Will this hurt the block or can it hold?

it will be fine. example: my bro has a b20v setup w/ only arp rod bolts, arp head studs, gsr crank girdle, gsr head, and he revs to 9k. so i think your covered to 8k.

No, unless you've got the bottom end built.

I've reliably ran my stock bottom b20v up to 7500 rpms daily. Its definatly one of the most reliable motors ive ever built. I love it everytime i start it up, such a great motor.

The key is to not leave any stones unturned or unthought about when building. Its a delicate process swapping everything over perfectly, but knowledge is power, and do your research.

You can PM me with any questions you have about the actual build. Ive done them with my own hands.

For it to last you need rods, pistons, and rodbolts. B20's are known very well for letting go.

Check out b20vtec.com.

No they arent. It's idiot builders who spread misinformation throughout the web.

Well my brother also has a b20vtec and he has a bottom end and takes it to about 7500. He said If I wanted to be safe I could probably shapien (sp) the rods and get new rod bolts, but other then that it should be fine. Just wanted to see what some other people thought. For those of you that say I "need" to build it, have you experienced this before or is it just off word of mouth? Im actually looking for people who have done this and been running it for a while to see what they think.

I am not speaking from experience but "knowledge". The reason I say this is because I was SERIOUSLY thinking about get a ls/vtec/b20/vtec, before I got my gsr. I have done hours of research and this is what I have found. If you don't want to spend alot then I say get some rod bolts and don't take it past 7-7.5, but thats just me.

Sure some of you have done it and been successful and some of you haven't been so fortunate. This is my opion and I'm just trying to help.

Proceed with the topic.

Thanks bro for the advise. Yea thats exactly what I was thinking. The rod bolts and taking it to only 7500. So thanks for confirming that. And yea, I might just go ahead and get pistons, im not sure yet. But thanks guys.

a b20 is a trimed down version of the b18. To make that extra .2 liters, they bored out the cylinders. Which means more stress and wear on the crank bearings. Sure, the b20 can handle the 7,5XX rpms but, how long?

What about putting in a GSR crank shaft. I was told it would be better then the stock B20 one.
