I am thinking about buying a B20 and boosting it. I know the cylinder walls are thin so you must get them sleeved, what kind of sleeves and what size do yall suggest? oh what do yall suggest about pistons? And would I need to buy any other internal parts so I can boost it and still have it be reliable? Thanks!

mr.speaker

I like benson and ge sleeves personally 85mm bore..wiseco pistons,eagle rods,arp bolts,and either oem,acl,or clevite bearings..

How much whp are you aiming for and how high do you want to rev? sleeves arent always necessary on the b20 even though people here seem to spread that around..

cova12

to be honest not really sure I have never done a turbo set up? What rev limit is usually used? I wanna get close to 300 whp? if possible to keep reliabe and fast! Fast of course! lol

its going to be fast..hell a straight b20 all motor in our cars is fun with the tq and all..

300whp is actually easy now days,,theres proven setups..

typically you'll see stock block b-series,t3/t4 e trim,450+ injectors,upgrade fuel pump,turboedit or bre for obd0,,crome or uberdata for obd1..

If using the stock head,cams,valve size,etc the stock rev limit is fine.

sleeving is up to you..I'm not going to try to push you either way I'm just saying its not necessary ..

But I'll be honest with you,put a vtec head on there and you'll make the 300whp at less boost..Dohc vtec heads leave most b20 heads in the dust..

cova12

well i have been thinking about a vtec head it just seems like a lot more money to build. because a buddy of mine told me I would have to get head bolts, run oil lines and a lot more stuff. Is this true? If not let me know so I can set him straight.lol

mr.speaker

your buddy is right,it will cost more in the end.

ive read the thread about building a "reliable" ls vtec ..it will cost more than enough if u was to buy everything that dude listed to make the build reliable..

personally i think the b20vtec is already great! my brother and i did his 1st b20vtec for 1200 in total..(b16 tranny, b20 block, b16 head, conversion kit, head bolt) ran a good 12.6 1/4 in his crx..STOCK! put out 191/157 tuned by BSR.. it was "reliable" for about 3.5 years before the weak head gave out..we put on a 99 head on the block and its been running good in his wagon for about a year now.

i got a b20b long block in my sedan for 650, and a b16 tranny as a xmas gift from my brother. i bought ARP head bolts for 125 and a b16 head for 250..got a home made oil line kit (ran perfect in my bros 1st setup for years) all i need is a gasket and im ready for b20vtec..i really dont think buying a type of water pump etc is gonna make any difference..imo

sleeving is expensive..turbo is money, plus tunning (unless money isnt an option for you)..thats all i can say for right now....too buzz

IMO stock sleeve LS/GSR with a piston and rod build would be the most cost effective method. If you need more than 550whp, then consider sleeving....

What are your goals?

cova12

I want to make atleast 300 whp....If I can build a B20 vtec that is reliabe and not too expensive than I will do that but I need some advice on what to buy so I don't buy something I don't need. So if yall can help me out with a shopping list that would be awesome.

Like what ecu should I use for a b20 vtec? I know I need DA axles, shift linkage, and head bolts.

Let me know what else I need? Thanks for the Help! Appreciate it

Schister66

if you want 300whp, get a stock GSR block and run with it. I'm making over 300whp on a stock GSR block. A piston/rod combo in an LS or GSR will handle ~550whp; whereas, a B20 would need to be resleeved for that kind of power. IMO get a B18a/b/c and run it stock...you'll be happy with that i'd imagine

Well see I thought about that but I am not exactly made of money and I live in Tx. Motors aren't very cheap around here. So I looked to the B20, because it is pretty cheap and I figured I could get it sleeved, new pistons and rods and have a decent power outtage.....am I wrong? Or heck even just build the B20 vtec, I wouldn't have to sleeve it for a B20 vtec would I? Thanks for all the input I really appreciate it!

You're kind of wrong..Even though b20's are cheap,they're not the cheapest way to go to make 300whp...

integra B18 is the best choice..You can usually get full swaps under $500 with tranny,ecu,radiator,sometimes extra stuff..only problem is the motors are sometimes beat..

With the b20 you're usually buying a healthy motor ,but only the longblock and have to get everything else..

Well I was looking at an ls and a full swap is like 2200. I can get a B20 longblock for 550 or 700 depending on year. I know I would have to get motor mounts, axles, shift linkage, ecu and get it all rewired for obd1 but It just seems cheaper to go the B20 route. I was just gonna try and get ahold of a B16 head after I get the B20 and throw new rods and pistons in it. But hey if ya can show me a way that is cheaper with the LS or no someone that can cut me a deal by all means I will go Ls. I love the Ls its just I'm a little low on the cash.....so I figured hey make a B20 vtec! This is my first project car so I am learning....lol! Thanks again....I can't say it enough I learn a lot on here!
