    2017 LS3 Caprice
    Well, today it happened. Just sealed the deal on an 18,427kms August 2017 (Nitrite) Silver Caprice. One executive owner who lived 10km from work and just drove it back and forward to work. He left the company so it went up for sale early. I've priced a tune from Pavlo Motors who say they can give it a nice little bump in performance with all the stock gear left on that I'll definitely be able to feel for a very reasonable price. Later I might do OTR and once I figure out how to get a nice burble I'll probably do that too and re-tune again.

    I'm trying to find out when the last Caprice rolled off the line because August 2017 is very late so I'm hoping it's one of the last of the last (and of course best of the best). Also, do the HSV 340 LS3s have any special hard parts that differentiate them from the detuned LS3 in the standard Caprice or can I get (or ask for) an "HSV 340" tune with this stock motor?

    I rang Holden and got the full history. Apparently there was a rocker recall that was done. What was that all about? Anyway, Factory extra tint and Hayman Reese heavy duty towbar and for the Grandpa touch; factory fitted weather shields on the front windows. The original Bridgestones still have nipples apparently.

    Happy days.

    Had the car for a few weeks now and it's an awesome vehicle. Clicking up about 400kms a day. Was using various 98 fuels (Caltex and independent) but recently I tried BP Ultimate 98...TOTALLY different car!! I'm stunned at the difference. Really didn't expect it. Much smoother and noticeably more powerful with a lot more down low torque. Could the other 98s be that bad? Fascinating. No way I can go back to other 98s now. Also getting about 100 extra kms per tank so (even though I haven't crunched the numbers yet) I think the extra expense is worth it or at least "not that bad".

    I've priced a CAI, TUNE and possibly some tr-y headers and 100 cell cats with a tune from PPM and though expensive he's aiming for 265 RWKW which would give me all the power I think I'll need for my purposes. Any idea how much that might be in FWKW roughly? Numbers aren't as important as performance I know but it's nice to know.

    I could do with some advice though... I'm looking at some spare parts that were taken off a 2016 LS3 VF SSV. Namely discs, callipers, headers and cats and (the best part) a pair of rear bi-modal mufflers - all for less than $200 so I reckon they're a bargain if they all fit. My questions are;

    1) Are the 2016 (solid) discs and callipers the same as my 2017 WN Caprice? In other words will they be good for spare parts? The pads are about 16,000kms old and I'll eventually wear through the discs so I'm happy to store them until needed and the pads will come in handy I'm sure.

    2) Are the headers and cats any different to mine?

    3) Will the bi-modal rear mufflers bolt up to my existing exhaust pipes?

    4) I think these are electric valves on the bimodal mufflers so I'm guessing they'll need a relay and switch hidden somewhere so they will work either open or closed. Am I correct?

    5) Was quoted up to $500 for the above electrical work so is there a way to just leave the bimodal valve open manually? At least for now. And, how do you think it'll sound? I'm only after some extra ("civilised"?) V8 burble/sound. Not expecting it to sound like a 3" open exhaust LSA.

    Thanks in advance.
