B18C1 vs B18B
I currently am trying to get a project car. I am building a motor and then buying the car. I have a rev hard stage 2 turbo kit. I am planning on making more boost than it can handle. Im trying to trade that kit for a motor. I was offered a B18C1 (GSR) for trade. The mods are 6 puck clutch, lightened flywheel, skunk2 chipped ecu, engine harness, jumper harness, aem cam gears, stage 2 crower cams, aem pulleys, aem short ram intake, aem fuel rail, itr valve cover, shift linkage, and GSR axles. The motor has approx 70,000 miles on it I was told. I am going to build the expletive out of any motor that I get. But would a GSR be good to build and boost or just go with my plan and get a B18B because of the lower compression? Let me know what you would do and whats mods would you do to the motor? thanks

Re: (ghostskinner)
from a guy that already has LS turbo, i decided to pay the extra to have vtec. im currently on a GSR build, it rele comes down to deciding whether you want vtec or not. both motors have potential, so you cant rele go wrong with either. the LS will definately be cheaper but the ability to rev higher and have vtec, determines if you want a GSR turbo.

You said your going to be building it right? Why not do like the B18B block with a B16 head? Get the longer stroke block and the lower compression vtec head and get the best or both worlds!! The B18C1 trade sounds dope tho 
I'd do that over the B18B motor anyday.

well a stock LS block revs up to 7200 when a GSR can handle almost up to 8100 stock. the ability to rev higher is a big plus for boost and vtec engaged while revving that high convinced me even more to go GSR turbo.

i'd keep the turbo kit, get a ls block and build it, slap a nice b16a head on it , get you a girdle for the LS block...i know someone sells em..then you can safely rev higher

im not a big fan on LS-V Turbo. the thought has actually crossed my mind a lot but the ability to get a GSR short block at the price of an LS short block, i couldnt pass up the GSR block. Another consideration is that this set-up will be dropped into my daily driver so reliability is a big concern. the extra money to spend on a dependable LS-V conversion is not worth it to me so i decided GSR turbo is the way to go
i loved the torque that my LS turbo has given me but again, im sacrificing torque for VTEC...

Why do you say an LS/Vtec wouldn't be reliable? In the fact that it'll probably be a safer motor to be running boost on due to the fast that LS sleeves are known to be a little strong? When it comes down to reliability tho, it's in the tune.

dude... definately B18B with a B16 vtec head!!! There's nothing to break! If you build right that motor will handle easy 800 hp!!! There's nothing to worry about. get ya some Crower or eagle rods, piston of your choice, polish the crank, balance the motor, Supertech valvetrain, gsr cams. that's as reliable as it gets. You'll be good to rev to 10,000 rpm if you wanted to. I'm building pretty much the same thing right now. The only difference in the LS block and the GSR block is the long stroke to make for more torque, and the lower compression in the head. Other then that, once you build, everything is the same... The stock B16 flows a little better the the GSR, if your doing port and polish that won't really matter either so. I would buy stuff based on what you want for hp?

LS-V will always have a bigger reputation of not being as reliable as a straight GSR. theres a lot to take into consideration when building a reliable LS-V. LS-V turbo will definately make more power i know that but i rather stick with the original design of the honda motor supplying sufficient amount of oil to the head correctly rather than through an oil line. There will also be a required amount of oil pressure needed to supply the head thru that oil line and still supply a sufficient amount of oil to the turbo. You also have to worry about a PERFECT seal from the oil duct in the block that originally supplies oil to a non-vtec head, and perfect seal in the head to avoid leaking in the gasket.
im not against LSV Turbo at all, ive also considered it myself but for my daily driver, LSV turbo wasnt considered a dependable daily driver. for LSV Turbo, everything has to be built correctly the first time and for higher boost on a LSV, more building is required.
