Look at inline Pro's 2.5L Stroker kit.

They put down 239rwhp and 193 TQ. I think that's about 40 over stock for each.

I know it's not the same as a 2.4L, but I'm assuming it can give you a rough idea.....probably just a bit less torque etc...Maybe in the 230rwhp and 185 tq area?

 

i love the wild-ass-guess approach ...

it's very scientific ...

 

That's pretty cool. Anyone have dynos of this? Cost? Reliability?

 

Parts wise I don't think its that much. Machine work would prob be the bulk of the cost. I might try this, IF my motor dies soon. It shouldn't, but If something happens to happen then I might do it...

Tuning would be fun!

 

You like that huh?

I couldnt find dynos of a 2.4L stroker anywhere but figured I'd use inline's numbers to get some rough idea. I know the numbers probably arent very close but I know not to expect like 300rwhp and 300tq. I'd love to see some real numbers for this. I sent an email to the company who does the build asking for more info.....parts list, cost, dyno graphs, etc...anything they can offer.

 

cost seems to be 3,000-5,000 for other stroker kits. I'm assuming if a company put all the parts together and sold it as a kit it would be in the same range. Probably a lot cheaper to look at the parts they used and go price them out. I doubt if anyone knows how reliable it is since it seems to be a rather new concept.

 

I priced out all the parts they used in the instructions and it comes to about $1304.00 not including s/h.

K24 crankshaft - $700
H22 connecting rods, bearings, pistons - $604

 

HTG should offer a kit, lol.

 

I'm sure some companys will try it to see just how well it works. They make some good points. It's genuine Honda parts (which I like) and the cost for parts isn't bad at all. It doesn't look like tooooo much labor involved, but even if you pay $1,000-$1,500 in labor (10-15 hours)...you're still walking away with a great deal. If someone knew how to do the work themselves and didn't have to pay for labor (except machining a few parts) this would be VERY cheap.

 

Just because everything is genuine honda shouldn't make you immediately think that it'll work. I'd rather go with custom made parts for a major modification like this because that way you know the clearances and tolerances have been accurately measured and tested for the setup.

I'm not saying this setup will not work, I'm just skeptical about all of these different parts working together without any modification... I mean youre talking about sticking a H22 parts on a K24 crank... 2 different sets of parts from different generations of engines. And then sticking all of that in an F20/22 block... another completely different platform. The H22 and K24 parts were meant more for "mass produced" engines that would be used for regular cars (although the H22 can be argued); whereas the F20/F22 were meant more for specific sports applications and it is considered a "Type-R" engine like the special B18s made for Integra Type-Rs and Civic Type-Rs.

I personally would rather get a kit like the Inline PRO or Toda (I think) because they have modified their cranks and everything to properly work in the block after doing some measuring and testing to ensure that the parts can work together.
