blown H22 block. hole in itso

[Dynamic93-408]

So today my bros h22 blew a hole in the block. Still havnt taken the engine apart to see wth happen. What would.caused this? Btw turbo h22

[deevergote]

What would.caused this?

This.

Btw turbo h22

Stock block, I'm guessing?

[Dynamic93-408]

Yes sir stock block

[deevergote]

Then you answered your own question. Stock blocks don't hold up to turbo for very long. What turbo was he running? How much power was he making? What was he using for engine management? What injectors? What fuel pump?

[Accrdwgnguy]

Rod broke. There isn't much else in there that would poke a hole in the block

[Dynamic93-408]

Walbouro fuel pump, 12 lbs boost, aem gt 35 and fuel injectors

[wildBill83]

And ... detonation!

I'm guessing no tune?

[deevergote]

I'm done trying to pull any information out of you. You clearly don't care to give us anything to work with.

So I'll just go with my first answer, as I'm quite sure it's correct... stock internals are not suited to boost. That's why it blew up.

[Sordz]

Even if the tune was safe with that size turbo and those boost levels the stock rods just couldn't take it.

[Darkcloud]

Another thing to is did he run the oil lines right, heard that can cause issues such as what happened

But yes a stock h22 on boost isnt wise to do. I also say he starved the oil or used the wrong kind, turbos need thicker oil. I have seen broken ringlands from a turbo h which is common but to blow a rod is common as well.

I still want to say wrong oil or starved it and spun a bearing. How long has it been boosted

[MR.PHIL]

Deev s right , H22s rods are normally the first thing to go out when it comes to force induction ,next common thing is oil starvation which causes lots of wear on the rod bearings eventually spinning them .

Thanx for the advice guys. We had the car at the track 3 months ago
Beast ran 12sec full interior cant imagine what it would of run if we had gutted the interior. What block would u guys rec to get this beast back in action? Btw it was our first swap with h22 turbo. Could of used more help on this project.

[SOHC-FTW]

A built one is the best solution.

[deevergote]

Built H22 block. Look into Darton or Golden Eagle sleeves, and quality forged internals. The head may have taken damage as well, so have that thoroughly checked.

A PROPERLY built H22A will probably cost over $5000... so be prepared.

Usually the pistons are the first to go, as they're made of cast aluminum (not intended for the heat or pressure that comes with forced induction.) The rods aren't designed for it either, though.

help is not what you need, research is, and there is a big difference. the information is out there, on this very board even, you just have to go out and look for it. for the money you wasted blowing up an h22, you would think you'd want to think it through and find out what works and what doesnt. thats just me though, i dont have a grand to blow on destroying shit.

also, an h22 block is an h22 block, there are no real choices (aside from the h22a4 with larger crank bearing journals) unless you want to go to DART and pay for a billet block.
