I wasnt sure where to put this thread since it isnt model specific or tech related more of a discussion. Anywerds

Stuck on what to build. I have a b16 head, a gsr head and a gsr block. I read a regular gsr will put down slight more power than a poor man type R also what kind of pistons should i run? Aftermarket gsr pistons or type R pistons? Would like others opinions on what to do. I also have a ls crank/ rods and block. Could put ls internals in the gsr block and have a stroked poor man type R? Or build a lsv with a b16 head. Decisions decisions. I jumped into this project without a plan in mind but i do know i want to finish a gsr engine. This discussion is just to get some ideas bouncing around. Let me know what you all think!

real answer - ls crank in gsr block with some type r pistons with gsr head because slightly higher compression

GDD answer - hondas are for poors

Really I think this depends on what your trying to do with the setup. For the most Power out of the parts you have, I would get the GSR block honed to 81.5mm, use some 81.5mm PCT (CTR) pistons, use the 89mm LS crank for a little added stroke, and the GSR head casting for a little added compression. Put that together with OEM bearings, OEM gaskets and some half decent cams (CTR or better) and you will have a solid 200+ HP engine that will scream on track. If your just looking for a fun but simple daily driver, use the LS block/rods/Pistons/crank, get an LSVtec kit, use the GSR head, again for a little extra compression, and have a fun 180-185 HP setup for your street car. "Poor mans" type R is over rated. We get these Type R piston GSR blocks with a stock 87mm crank and B16 head combos all the time and the owners all think it's going to be an insanely powerful race engine (because Type R Pistons, duh) but in the end they spend twice as much money to make the same Power a well built OEM part LSV would make.

If you use that LS block you will have to run a catch can as you would have no PCV system with an LS block / VTEC head. And an oil line kit.

This. But you may need to modify the crank to clear the squirters. That setup would make the most power.

Frankly if I had a complete GSR I would just go with that. Why not just put the GSR together and slap the B16 head on the LS block? Wouldn't that make sense? 2 engines right there.

It's skip the squirters completely if going with an LS crank, and not modify the crank itself. "moving" the squirters is hit/miss, so I'd get a Golden Eagle oil squirter block kit and go from there.

bore block, balance crank, 85mm rs itr pistons.

For GSR or LS block? Are you high?

Lau Cac Bo

Sometimes I'm high, yes. 85 mm sleeved.

Lol ok. SLEEVED makes better sense. B20 block IMO is a better option if cost is a concern.
