So I'm browsing eBay on H22A blocks and parts, and I see the following:

http://cgi.ebay.com/ebaymotors...33613

"H28-H30 turbo/NA/ Nitrous 2.8L, 2.9L, 3.0L special boostable 92 mm bore x 104, 108, 111 mm stroke using a new billet crank , R/S ratio is 1.58: 1...full engine build with external oil pump ,wet sump $13,995.00 core charge $1200 extra"

Is it me, or is it hard to swallow that someone can make a 3.0L H22A using 92mm bore (extremely thin walls) and a 111mm stroke?

 

sounds like a bomb waiting to happen for me. with something that expensive, I would rather take that change and build up a 454 SS block and add a blower. you could get a lot for 14k or let alone a downpayment on a new C6 or something better. I wouldn't spend the money.

 

I dont think that motor will last

 

me too the largest bore i have seen was a 2.6L

 

Seems like the seller is pretty knowledgable about his work, however that never determines anything....Hell Toyota puts a 2.8L 4 banger in their trucks...

 

well if you look at the pics, the walls dont look too thin...

 

thatd be sweet, but kinda hard to believe it would last

 

when it comes to being different you can only go so far. id get something more reliable for the monay

 

well if u got a house... car already.. then why not...

 

is it just me or are those prices just outrageoulsy over priced?

im building my motor top and bottom end... im not even at that price range

i'm not sure man, but i think the pics shown of the walls for the 87-89 mm bore.
i think with the 92 mm bore the walls would be thinner than what was shown in the picture.

sounds like a bit of a risk to me for that amount of money.

 

i have an 89mm bore, didnt even think of going beyond that b/c the cyl walls will be very thin and if i crack a sleeve theres little chance to save the motor with to more than an 89mm bore.

 

not worth the money to go and have ur walls crack, not saying they will but...if it did..wat a wassteeeee...and we all know the chances of it lasting arent great so..but yea

 

I am skeptical about this. I mean, by no means, I would purchase it. Just wanted to let you guys see it.

I also talked to Rick Solis and asked him about this motor and this is what he replied with:

To acomplish the 92mm bore in a block with a stock bore spacing of 91mm you have to offset the rod location in the piston moving the piston over Xmm to the left and right of the center of the block.



Although this can be done doesnt mean it should be done. There are a lot of downsides in doing something like this. First would be the most obvious, the combustion chamber and bore overlap as pictured below.



This means the pistons will have to be custom, moving the valve pockets over to ensure the alignment of the valves and reliefs. So your basically going to have completely offset pistons with the rod positioning and valve pockets moved further to one side of the piston. Theres no real way to redirect burn through out the combustion process, with this set up your going to have 3/4 of the piston absorbing and distributing the major part of combustion while the other 1/4 will end up a carbn pool.

Another thing that isnt the best aproach would be the ridiculously large 115mm stroke. The piston speeds generated by a crank that size is just obsurd. At 7000 rpm this motor will be generating piston speeds of 5282 which is insane.

not to mention the custom offset gasket that is required which doesnt apear to be able to provide adequite seal

I doubt that one of these motors even exists past the idea stages, If so Id like to see a dyno sheet and some prrof that this thing can live past one stomp of the throttle...

 

dang, nice info...and drawings...

honestly...that just seems like too much work for an h22. dumping 14k into JUST the engine buy is insane...maybe doing a built engine with turbo set up and dyno tuned with everything perfect, that would justify 14k...but 14k to just start?

wow...yeah.....like it was said earlier, downpayment on a c6

 

Man, this has come up once or twice before. It's like every time he relists the motor, it gets a huge thread!

Nice, but it's way too much money for what it is.

i was just going to say, REPOST ..

there is some good ideas and bad, but in this case they are all taken to a way extreme, ill stick with my stock 87mm bore thanks,. and stroke, well thats a different issue... right pirate??

 

let me put it to like this..this guy is from my area and nobody knows who he is...
