sleeves on a turbo h22?

Question

i'm looking to turbo my h22 but heard the cylinder walls are thin and cannot handle much boost, if i have to do that around how much does it cost to do that?

Answer 1

If you're gonna spend the money to build it, spend the money man. Darton sleeves installed are usually around $2000 after milling and decking the block, Get some nice rods and pistons ( I recommend Mahle pistons, any rod besides stock should work, thought if Carillo makes a set get those ). My motto is build a motor for 700+ hp and run 400 through it.

Answer 2

I know a lot of people who have mounted a turbo on their engines then blamed the weather when the engine burned up.
A turbo jams air into the engine and in doing so the air heats up which can cause pre-detonation. A heat exchanger or inter-cooler as it's called, is always a good bet.
This is what is needed to handle the additional horsepower and the heat that hosepower will generate::
.
A bigger intake tract, and a bigger air cleaner.
A larger diameter exhaust outlet.
A different muffler tuned to the new output.
Stronger head bolts.
An all metal, thicker, head gasket,
heavy duty valve springs
A larger oil filter
An oil cooler.
Bigger radiator
Large capacity oil and water pumps.
Heavy duty clutch.
Bigger drive tires to get that power to the pavement.
.
If you don't believe me, check out the parts/options list between a turbo equipped car and one with out the turbo.
.
You'll see it might be better to sell the H22 and buy the turbo model.
You'll also get a factory warranty on the turbo engine, something you won't have if you do it yourself.
No Turbo kit maker gives a warranty on your car's engine, only on their parts, and only if you follow all the directions including the fine print.

Answer 3

H22 Sleeved Block

Answer 4

Yes, you will need to sleeve the motor when going with forged pistons, unless you use a Mahle forged piston with the Honda gold coating on it so it drops into the motor without the need for resleeving. The gold coating is so the pistons work with the H22's fiber reinforced matrix cylinder bores without any problems.
If your looking to make 300hp, the cheapest route would be the Mahle pistons. If you looking to make 500hp, sleeve the block!
Sleeving is at least $800 and I have seen people pay upwards of $1200-$1500.

Answer 5

Its not really that they are too thin, its because they are made of a composite aluminum material, they are too weak for anything above 7-8psi. Fully tuned with a stock bottom end will and has been proven to put down over 300hp on 7 psi. Anyways higher boost levels means sleeving is an absolute must, it costs me 500 to have my h22 block sleeved and decked. I bought darton sleeves separate.

Answer 6

how much boost is the question ? add pistions and rods you could run around 17psi maybe even 20 psi with the right turbo and management could produce 400-475 hp

Answer 7

depends were you from dude like hear in australia its about maybe 900-1200 bucks
