Well i decide to go with a new clutch and bought it for a type-r tranny form summit b/c nobody in the southeast that i know of had a clutch in
so i go home and try to install it but it didn't work the spline shaft on the clutch was tobig it hit the spline sleeve on the tranny and would,nt allow the tranny to mount to the block so after about 3 hours of wat to do next we looked at the old clutch and the new clucth and noticed that the new clutch spline shaft is 1 1/4 in and the old clutch shaft is 3/4 PROBLEM so the i thought all b-series stuff was the same but that is wrong as u will find out well i decide to to if a ls is diffrent b/c its not vtec just like the b20 and the gsr and type-r are vtec so i found out there is a diffrence b/w nonvtec crankshaft and clutch and vtec crankshaft and clutch dont ask me y it is but it is and u can use ls clutch on any b-series motor but u cant use a vtec clutch(b16,b18c,b18c5) on a non vtec block


if u think i am wrong go ahead and go to nopi or summit or call zoom or competion clutch or centerforce or even Exedy they will tell u they make diffrent clutches for vtec and non vtec motor



sorry if there a any misspelling on this i am not the best typer or proof reader
