Running the stock B20 bottom end would be an accident waiting to happen. At least invest in some ARP rod bolts and a decent water pump. Plus if you run anything bigger than stock B16 cams, your valves will collide with the pistons.

IMO if you are low on funds do an allmotor B20! It has way more potential than ppl give it. A vtec head is nice, but if you have never built an engine before than I would recommend staying away from trying to going Vtec head unless you have friends that are willing to help! Consider as well if a shop has to do your work then you will shell out a butt load of money! Machine work is cheap for a nonvtec head, and so are parts(really cheap). Alos if you ever blow an engine, a B20 or LS is easy and cheap to replace!

Not exactly! Its true that the B20 block has weaker walls than the LS and it uses the same internals as an LS block, but it can still tke a lot of abuse! However If you plan to take it higher than stack redline you should shotpeen the rods, and use ARP rod bolts(8mm)! And if you think the cylinder walls will be a problem then buy a block posting kit from endyne and use the tech article on http://www.homemadeturbo.com to give a guide on how to do it! Also Endyne and Import Builders makes great pistons or these motors!

 

i want to go b20 vtec jus because its VTEC. i know its cheaper to go b20 all motor but i dont mind witin to save up some money to go b20 vtec. one of my friends is gonna help me hes got a b20 vtec that he put together so im good on that part. also if i ran an ls tranny on that would it be alright. i heard that i will fall out of vtec because the gears are too long.?? ion though. would stock b20 rods shot peened and wit arp rod bolts be ok for like 11.5:1 cr and a 50 shot?? if not, then eagle h-beam should be fine huh?? thanks alot

 

go b20 vtec with pistons and rods

Then take your time and go B20 Vtec! Make sure you do it right and do not cut corners or halfass it!

Do not use the LS tranny, try your best to get the b16 or an ITR tranny!

B20 rods shotpeened will be fine! This will cost you somewhere between $60-80! If you rather use aftermarket then get Eagle Rods($350). Also ARP Rod bolts(8mm) will run you $30-35 and a machine shop will have to press these in for you too, however if you take it to them when you go to shotpeen the rods they probably wont charge you and if they do at the worst $10-15. Look at Endyne and Import Builder's for some really good Pistons for what you are going for!

Well you want more than just Pistons and rods! If you are going to build then do it all at once and drop in the motor you want!

Here use this dynamic compression calculator to help you select the proper compression level for the cams you would like to use! Most ppl say you want to increase cranking pressure by 20-25% for the best results! Stock LS and B20 cranking pressure is 189 PSI.

http://www.rbracing-rsr.com/comprAdvHD.htm

You will need these measurements:

Bore: 3.189"
Rod Stroke: 3.504"
Rod Length: 5.394"

20-25% increase over 189 PSI is: 226.8 to 236.25 PSI(This is consider the sweet spot)

You will also need cam spec for the cams you would like to use. You need to know what degrees the Intake Valve closes!

Hope this helps. Good Luck!
