ok so i have a b20 vtec...no major upgrades besides headers and exhaust ...how much would i be spending to get upgrades for a turbo? what would need to be done to my b20 bottom block?

anywhere from 500 to 10k. hahaha How much do you want to spend is the question !!

all depends on wat u want ur motors final results to be... heard b20 sleeves are weak but can handle 8-12psi tuned correctly... you can get it resleeved, maybe lower pistons, rods.. all depends on if u want to open up ur block and start buildin for turbo or wanna jus slap it on ur as-is setup. and cost for turbo depends on wat kind u want too.. piece it together from 800 to 4K+ for edelbrock set up... all about the money u want to spend

Sleeves, rods, pistions.

Fix the weak *** bottom end and upgrade the valvetrain.

Though it would probably be cheaper/more beneficial to turbo a non-vtec b18b over that b20.

At least then you wouldn't need rebuild the entire bottom end.

If you do go with the b20, remember, it's a CRV motor, not a b18b + .2L

The rods are weak, the sleeves have shitty casting. It was designed for low end. It was in an SUV.

How much hp you looking to make?

Forged pistons and rods, bored and sleeved cylinders, and a block guard to start.

The bottom needs a lot done to it, don't let any idiot tell you "it depends on the tune" - the B20 block bottom is weak enough, winding it out even harder w/ VTEC is bad enough as the block SUCKS to be revved on - so it needs to be built from there - then pile boost ontop of that - you have a 4 cylinder pig-expletive.

Must sleeve that bottom end to be safe

wuddup man, i just had a gsr with drag turbo on 7 lbs..and now i just built a stock b20/vtec as well and im gonna turbo it with the same kit on about 6lbs...im aiming for around 240-50hp to the wheels, if you can be happy with those numbers then dont touch it at all and the drag kit all together new with accessories will be around 3k$...

The key is your goals & budget. Then you can decide if it can be done and for how much.

it woulda been better if i woulda went ls-vtec and turbo that huh? thought i was going all motor with the b20 and i'll be happy but its still slow
