Ls1 Throttle Body Differences

[feistl]

Hey guys,

Just wondering if anyone knows the difference between the VTII and VXII LS1 throttle body and the later VY+?

Apparently the "cam rate" is different, i am wondering which is "slower" when opening? (EG was the later model more aggressive or slower)

Cheers, Errol.

Is that you Errol vt vx and some early vy had a smaller throttle cam late vy vz large throttle cam to have a more progressive throttle feel.

I thought the late ones had fbw (electronic) throttles?

[Bling Bling]

Yep vz had fbw.

Yeah mate, Thanks for that. Ill see if i can track down a VY style TB.

Cheers

I honestly thought that I had seen at least one VY with fbw?:confused:

Some very late VY HSV's got the VZ motor with FBW, I don't recall seeing non HSV's with it though

They must be round somewhere, I got my conversion from a VY SS and has FBW.
Thanks for the message Errol, will give you a buzz re the adaptor

Only Adventurers in VY2 had FBW

Yeah a mate of mine had a VY II Clubby, that might have been where I have seen one?

Kind of makes sense, seen an XUV with FBW, so thinking all the AWD models?

[macca_779]

Yeah same same. But no 2WD cars had it

I must have been wrong then,
I know you would certainly know your facts on this much better than me macca
