bisis has changed his motors more than anyone can keep up with


I promise that motor in his car now isnt a destroked 2.0L


All Motor=Go really big why all the k24+motors make so much power

I've got the LS crank, rods and pistons in my B18C. The torque gains were barely noticeable. It just feels like a really strong GSR motor. Got maybe a 1/2 car length on the identical swap in a 2nd gear pull to redline and we were running an identical ignition map. I'm about 1/2 point lower in CR than him at 9.67. It was considerably quicker than a similarily equipped B16 swap. I used the LS pistons and rods to avoid coming out of the hole too far. Had to mill some oil squirter holes in the piston skirts. With a shorter rod I could have used the GSR pistons or some B16 ones.



With turbo it should be just fine. The trouble with stroking the ---- out of these motors is the extreme piston speeds and a lot of side loading on the sleeves. B series motors don't take well to this. As a result you won't be able to spin it to 8500 every day and see it last. With the longer stroke I've beat the hell out of my B18C1 but I kept the rev limit at 8250.

Given the costs involved it would be a tough choice to stroke out a B when the H or the K are reasonably priced. I did mine with spare parts left over from other engine builds and got the engine with spun rod bearings for $400. If you have a B16 and you're going to crack it open for a freshening up then yes I'd say it would be a part to look at.

if you crack open a b16 for any reason it should be to add a GSR, LS, or b20 bottom end, the only thing b16's are good for are the heads

Tom-Guy

Eh, I've revved LS bottom ends to 9500+. With enough boost there's plenty of power up there.

Racintweek

as long as you dont go way big on the bore the side loading isnt a prob, the reason you cant rev an LS is the rocker arm design, not the R/S ratio BS

SkunT

yeah, how much does a K swap cost, doing it yourself for a true K20A R motor, your gonna spend an easy $6000+ on parts alone, for a stock motor. You could build a B series motor that would whop that *** for much cheaper. Not to mention the K motors won't be comming around anytime soon to put them within a budget of someone who isnt on mom and dads credit cards....

hackish

It's not going to happen running an LS bottom end. 3mm isn't stroking the ---- out of the motor. Sticking in the 95mm crank is not as likely to rev to 9500 for very long. Off the top of my head the B16 with LS crank gives you a R/S ratio in the 1.5 range which isn't nearly as rev happy.

h series head flows almost has much has the K


simple h2b owns all motor

88dx

Fixed

Tom-Guy

Gee, I dunno about that, 88DX. Some H22s run pretty strong, and can own 170 whp turbo D15B2/7's all day long for only seven times the price.

Seriously, a really hot stroked + bored NA engine is a LOT of fun to drive. They don't make nearly enough power to be worth a fraction of the money that goes into them, but a lot of people are NA dumbasses and insist on going that route. If these are affrordable stroker cranks I can make the local dildoes build really hot NA engines for me to play with and I don't have to spend a dime.
