I was wondering (since I am not to knowlegeable on B series motors) if the gsr crank/rods would make me a nice bottom end to go into a b20 block....

Thanks for the help

yeah it would go in but i personally dont think its worth the work..either save for a sleeved B18C or just stick with a B20...

you would need custom pistons.

B18C internals will not work.
81mm vs 84mm

Hey can I use b-series pistons like pr3 or pct in a b20 block??? or i need a bigger piston???

You can use the gsr crank and rods but the ls crank will produce more tq. more displacement more hp. If you use a b20 block you can only use b20 pistons ( no other b series piston will fit as mentioned above ) of off the shelf pistons from either import builders, CP pistons from eARL, endyn, je and etc.

go get some wiseco piston's from import builders.. they got pistons for 2 liters

Yes it will. You're just talking about the bore size there, so obviously you need an 84mm piston to work in a B20 block. But the LS block and GSR blocks have the same physical space inside of it, thus a GSR crank w/GSR rods will work in a B20 block, giving it a shorter stroke. I know because we built one 2 months ago with that setup for a customer. Same applies to putting a LS crank & rods into a GSR block.... LS rods are shorter but the crank provides the longer stroke so it compensates and works. That's basically what I'm doing to this spare B20Z block I have here.... gonna try and find a GSR crank for it. Either that or drop a B16 crank into it (yes, it'll fit also but you need custom B16 rods that are 7mm longer than stock) and run a destroked 1789cc motor.... dunno yet really but to answer the question, yes the internals will work, as we've done it already.

I understand that everything BUT the pistons will fit, I should have elaborated more, and I also understand that you know your ****...BUT why would you destroke a non-vtec block? I'd rather resleeve a C1 bottom and bore it to 85mm thus haveing the block girdle that will really aid those high revs than destroke an engine to make it support highre revs when it was never designed to possibly do that.
I only meant the pistons wouldn't drop in.

Hell, I'd love to have a C1 motor and bore it out, throw on a deck plate, and build it up for high compression, but with what I have laying around the shop and funds allotting me to work with, I figure this would be a fun setup to drive around in, in a small car like a CRX or EF hatch..... already have a GSR girdle so I can make that fit . Basically a "big bore" B16 setup that'll rev happy. But if you have a spare C1 block you don't want, I'll take it and play with that

Read some of the articles here about blown motors and maybe you'll start to see that the GSr's internals are not the best. Type R on the other hand seems to be tight. I haven't read near as many complaints about stupid bottom end problems with the B18C5.

Ummmmm 2.2 deckplate B series, I saw a dyno of one a while back and it made 230+hp and 180+ftlb, a real beast all motor.

The gsr crank is very strong. Have the rods shot peened and polished. However the piston specs need to be looked into. Is this going to be nonvtec or with vtec head? LS crank and CRV cranks are exactly the same.
