I have a blown turbo ls vtec setup and im not sure which route i want to go next without having a million dollars. I have the b16 head with new valves and seals from the blown motor which will be going to the machine shop to be checked for sny issues. I will be using the accessories from the blown motor depending on how they look since they were brand new and the turbo kit. Im not sure whether to make this motor an ls vtec and going through the steps to make this one work properly, or get a gsr block that is half decent and just put the two together. Ive ben researching building a propper ls/ vtec setup and im thinking of trying to get away from the hybrib. Can anyone give me some direction i cant seem to locate what i want to hear from the archives. What im gettig at is can i use a gsr block with a b16 head new head gasket and head studs ad call it a day with some tuning or is it not that simple. Thanks for the help

 

you can use the gsr block with a b16 head. your compression ratio will be down roughly .2:1 thats the same setup i have.

if you use the ls bottom end, your displacement will be a lottle higher due to the ls's longer stroke.

 

put the ls crank and rods in the gsr block and use the b16 head. thats my exact motor setup and ive been making over 400hp with it for 2 years now

 

Agreed.

 

Please forgive my ignorance, what’s the difference between the LS and GSR block?
We don’t have the LS block in the UK only the GSR.
The route we take is GSR or ITR with forged internals with either the ITR head including cams + valve train or B16, some use a GSR head (C1) because of the larger quench area with any combination of cams etc.

 

Well. The LS block is somewhat of a hybrid. It uses the crank that is similar to the Honda Stepwagon B20 crank and rod length, but retains the 81mm bore of the B16/B17/B18. The benefit of using the LS/B20 Crank is additional torque (on average about 10ft/lbs in an NA configuration), yet it still retains some high revving capabilities (about 8500-9000) if properly configured.

The route that you're used to EddieCRX is just as common, but in the U.S. we have the ability to change a few options that Honda gave over here.
