You have two of the best mechanics I know in this thread. Both say Ls/vtec. We have one of each b18c jdm in one Teg. Fully built b18 Ls/vtec Turbo in the other. I cant really compare the two because of the turbo factor. If it were me i would go with a b16 head on a LS.

Shemi good luck on beating the green monster

 

gsr has 1ft lb more torque than an ls idk the point of ls/vtec, poor man gsr lol?

 

yupp thats why i like it,its alot cheaper to build up a Lsvtec then a gsr to make it faster for the goals you want..the only thing gsr block has that ls does not is 2 more oil passages and a spot for a knocksensor

 

and in the end it makes more power

 

id have to go with ls/v even tho also like terry i am goin b20/v

 

i have a ls/v. gsr head, p30's and other mods work nice for me

 

The gsr has a way better flowing head than the ls and thats why it has more tq by 1 point. Most people dont realize that most of your power is made in the head you just need a strong bottom end to hold together. Now the excellent flowing head on the ls is better because the ls is a bigger motor than the gsr. Yes they have the same bore but, it is also the stroke that determins the cc of an engine.

Code Disp HP@RPM TQ@RPM C/R Stroke
B18B1 1834 142@6300 127@5200 9.2:1 89 94-01 LS
B18C1 1797 170@7600 128@6200 10.0:1 87.2 1994-01 GSR
B18C5 1797 195@7800 130@7600 10.6:1 87.2 1997-2001 ITR US
B18C 1797 210@8100 130@7600 11.0:1 87.2 1997-2001 ITR JDM


Notice the higher C/R on the gsr? That along with the better flowing head makes what 28-68 more hp and 1-3 more ft,lb of tq? Now remember the type r comes with a better port job than the gsr. My previous set up was a B18B1 Block with pr3 pistons (not quite 11.0-1) and the US itr cams (the shittier ones) and UNTUNED I made 191whp 137wtq. This isnt at the crank like all the numbers above.

ls/vtec untuned
b18b1 stock bore
pr3 pstons
gsr head with type r cams

 

That would be slightly hight c/r

 

stock ls with vtec oil and water pump and golden eagle ls/vtec kit is what i did on my budget build

 

water pump yes oil pump is fine
