that's great to see that it's legal to fit these engines in S30 in QLD. it is so hard to find info amongst engineers. every one has different opinions on what you can fit in. i spoke to three engineers (meaning: mechanics that do mod plate) in this stinky town and i found out that 1 said max 5L, the other is not quite interested (he couldn't be bothered to read the rule book -too hard), and the last one had been a pain in the butt. he wanted to have every single welds on every modified brackets engineered approved! argh!!
maybe i should go back to them and say, look it can be done :)

Curious as to why it has Rims, Tyres, Suspension & Steering Modification Code LS2 (LS2 is nothing to do with the engine - just a coincidence).

As I understand it LS2 is related to LHD to RHD conversion. Was it something to do with the steering rack?

one of the reasons i got mine passed was because the engineer who signed off on it who is one of the most reputable engineers around knows the guy who fabricated it all and fitted it up. 

He knows the fabricator does not cut corners and is not some back yard knob with out welding skills. this helps when the engineer knows the quality of the work.

the steering arm was re-directed with a knuckle to fit the extractors, thats why its got the ls2

i have a price, im looking for about $8500 ono for it all. that includes pretty much everything, it would just about be impossible to buy the parts for that without any labor. it cost me well over that.

i have no problems with the engineers being picky with the worksmanship. they just have different interpretations with regards to engine the size  :(
Eg. your engineer gave you the approval to fit an ls1 engine, whereas they only told me that they will approve it with max capacity of 5L ,professionally fitted or not :(

your engine package seems reasonably priced. goodluck with the sale.

I can't quite make out the Mod Codes. Could you confirm they are LA1, LB1 and LS2. Could you also provide an image of the plate above the one in the photograph - thanks.

If you sell your car as a going concern in QLD it will still obviously be inspected, but as its already QLD approved it will just be a roadworthy for transfer, so no probs there and by far the easiest solution.

However, I take it you have the relevant paperwork to go with each signed off item / mod / conversion, this is proof that a certified engineer had inspected and passed the mods on the same model car, youll find the RTA in each state will have a list of selected engineers you can have a chat with....most regs are the same Aus wide with a few minor variations here and there, its a case of doing some homework........or you could just tell them its a 5Lt :D

I don’t really like to get too involved but this is a topic I know something about and I don’t want to see tears, from either side, further down the track.

This vehicle has been approved to NCOP LA1 which means it is approved to have no more than 20% increase in engine weight and/or power. An LS1 clearly represents more than 20% power and therefore it should have been approved to LA2 requirements.

If the car, as presently modified, is taken interstate (other than NSW) it would have to be re-approved to LA2 specs. There is probably nothing stopping it being approved to LA2 but a buyer should be aware of this. However, as it is only the LS1 components that are for sale then perhaps I’m getting ahead of the game.

Regarding NSW - At this point in time the NSW RTA has still not adopted the NCOP standards and you can only install an engine of 5.3ltr capacity.

I've taken it as a throwaway line but if you think you could pass off an LS1 as a 5.0ltr, then go ahead – the approving engineers will stitch you up good and proper and you would have wasted time, money and effort.

thanks for that info,

im talking with the engineer today hopefully to find out some finer details about its legality in other states. 

an to clarify how it got through. as before the conversion was started the engineer was consulted on numerous occasions through out the process as to keeping everything legal. I might add i paid dearly for his advice and if wrong he can buy it.

the whole car is forsale selling it complete in qld with a qld mod plate looks like the easiest way. and should know later today a bit more.

Interesting thread. I am not up to date with all the rules these days and not sure when they were changed or updated. For what it is worth my V8 then 5.8litre was engineered over 15 years ago in Victoria and I don't think engine capacity was an issue back then. Now it is 6.2litre and no recent RWC or RTA has raised any questions regarding all the below here in Vic. Maybe it is exempt since it was approved so long ago or not an issue after you get the big tick.
Either way I reckon your price sounds more than reasonable for any serious buyer who is thinking of doing a conversion. Good luck with it.

I must have this wrong... if you are stating that it's $8,500 for the complete car as is, then that is ridiculously low. Any V8 owner will tell you they cost that much in incidentals alone.

by the way i read the post, the $8500 was for the LS1 conversion bits in a package, and the discussion of selling the WHOLE car came up after that price was posted...  i think

Yeah I thought the price was too good to be true :) lol
Yes, I reckon it is more saleable if it is for the whole car.
If only I had some spare cash, i would sell my ongoing 240z project car and buy this. It would save me all the headaches with regards to legalities.
