N/A VL mods

[SlickNick_]

Hey ive got a 87 s2 calais and i wanna get as much power out of the n/a motor as possible without bolting on a turbo. what ive got in mind of doin so far is:

engine rebuilt
cam
chip
extractors
exhaust
head work (maybe)

now with the exhaust is it worth getting a hi-flow cat convertor or a cat back? will either of them make a difference in power?

thnx in advance

XF throttle body as well

[Goon]

4.11 diff.

vt brakes for safety

[mking]

how much machining is in the xf TB to make it fit the vl?

[detox_nath83]

All here buddy
XF Throttle body - R31info

[VryNeat]

first things first there is NO such thing as a s2 vl second of all i think they have finally released a stroker kit for the rb30 so if your rebuilding it and dont wanna go forced thats your best bet

[detox_nath83]

makes it an rb33 when stroked
not s2 VL
but S2 Block :P

[SlickNick_]

yeh sorry i meant s2 block my bad :P

and with stroking it whats involvewd with doin that? and wouldnt that class it as a high powered car cuz the reason im not goin with the turbo is cuz rules are changing in adelaide so that P platers are banned from owning them cars

Ah nicko, i have the same problem (NSW) and the laws suck. I'm pretty sure strokers arent allowed, bcoz as u say, it would class it as a high powered vehicle.. any one with info and can help us out, would be greatly appreciated.
Oh, and i have a 4.11 Diff, whats the difference between that and the stock 3.45 ?
Cheers

are the VL's EFI or carby?? If carby, why not put EFI on it

[thedeadwalk]

vl's are EFI. thay are the 1st in aus to do it

(long LONG befor ford)

[snowybill]

was the V8 VL EFI as well?

[Tasmaniak]

not typically no. The VL V8 was a carby fed animal (read as "slug") BUT the VL Walkinshaw was the first injected V8 with a dual high rise throttle body.

VL was not the first fuel injected commodore either. The VK was released with the EFI 202

[snowybill]

ah okay i thought the V8 VL's were carby.. n quickly looked it up lol.
but yeah you're right anyways tas.
