Contact: Nick Email: [email protected]

Phone: 0416 283 194 (hours: 9am-9pm)".

Now, I know it's a Z engine & will reqire the sump mod which I will do if you're keen on this engine.

Ghostrider is right, this costs alot of money so be prepared to spend heaps.

Oh, & Ghostrider... 86mm/87mm pistons will go in a L24, I built one a couple of years back with triple webbers & it made 135kw@wheels, it's a daily driver & also does track work from time to time & is still going strong. However, I wouldn't do it to a turbo engine...

Nick.

Appreciate that but I am pretty keen to build my own engine and use my existing block so the numbers match. i understand that mods such as these require a lot of time and cash.

Thanks,

Paul

Nick, your possibly right.

I could probably fit them into an L20A block too, but the water jackets would be a bit large.

Your quoting SWR as an engine builder? Stewart Wilkins will never recommend an over bore of 4.0mm in any L series block. The cylinder walls would be paper thin and very suspect to failure.

You might have done it, but I'm sure not going to try.

I have 2 x F54 blocks and they wont take a 3.0mm over bore, as I had them sonic tested to find out, as I was going to build an 2968 engine, but am settling for 2818 instead.

I don't know that these guys would want to be doing it either, but I suppose ANYTHING is possible if you want it enough.

Cheers, D

im wondering that too, theres a few L28 (carbied) engines at my wreckers.... i can get one for $20!!!

The factory cams have codes stamped in the back end face and the L24E cam is NOT really suitable for a turbo application, but it has been used in the past.

The best off the shelf cams are L28E and will have the markings A or F stamped in the back.

The A cam came from engines origin prior to 8/81 and were in N42/N47 & P79 heads and F cams came from 9/81 onwards in P79 heads only.

Make up your mind!

You going Turbo or N/a??

Best of best off the shelf n/a cams is the one stamped C and it was in all E88 headed 260Z.

It is reputedly the Nismo works cam.

Ghostrider, I failed to clarify that the engine I built was 3mm over bore & not 4mm but have seen it done... I agree 4mm is playing with fire. In N/A trim 3mm is safe as long as the block is acceptable after sonic testing.

Paul... if you need pistons etc, I have a brand new set of 86mm with rings for $300.

Yeah! for sure.

I talk with SWR a lot and I was going to put an 87mm bore into my L20A and use sleeves, but the cost was preventative. The block would loose all of it's rigidity and it would be a mamouth task to complete and with custom liners, the bill would exceed $1500 after decking, recess grooving etc etc etc, so the F54 was obviously the better alternative.

These pistons & rings you have? Are they FLAT TOP and are the rings CHROME??

Just to let you know my plans, I'm building 2 N/A L28's at the moment using L14 rods. the 1st I'm using 86mm SR20DET pistons & E88 Skyline head with N42 valves (I believe it to be the best head combo to use), & the other I'm using 87mm VG30 flat tops with N42 or N47 round port.

Yes F54 block is what you want I think.

Lots of goof info on OZDAT forums

F54's were the 280ZX Turbo block and in turbo form, never came to Australia, but some of our n/a 280's had F54 blocks in them, but as far as I know, F54 blocks never came out in 260Z's.

And JC the cam would be fine, now or later.

Just don't play your hand when looking for the 260 cam, not everyone knows, but I'm sure if you tell them the price will go through the roof.

The 260 cam has 256 duration and for your relative stock L24E turbo, it will probably be a little long and the L28 cam should be easier to get.

Cheers, D

      Kinkstah, no, coilovers aren't illegal, especially as a bolt straight in. The illegal part will be if they're altering suspension geometry beyond factory limits, or the ride height is not legal.   Sounds like the blue slipper just didn't want to deal with any later possibility of mods appearing on the car.

      The problem has always been that coilovers are able to be adjusted, almost at any time, to be too low. Most people who ever get/got defected for/with coilovers were actually afoul of the minimum ride height rule. So the interpretation by cops/inspectors was always that it is pointless to allow numpty to raise his coilovers and get the car inspected/cleared, then just drop them back down again as soon as they get around the corner from the inspection station.  This led to the interpretation that they were illegal unless rendered such that they can't be adjusted (ie, collars welded to the body, that sort of thing). That may or may not have ever actually been the official line, but I'm pretty sure it's not considered to be a solution these days. Coilovers themselves fall under clause 3.2 b of that manual, because they are an "installation of a variable ride height system" and they don't fit the exclusions in that clause (which point to air springs and other pneumatic adjusters). So, as per previous statements, they require engineering cert to be legal on the road. Once you have such cert, provided you do not adjust them outside the height range covered by the cert, you are OK. Without, you have an unroadworthy vehicle.

      Ethanol Content Sensor - Always at 11%?

      Here E10 is the cheapest fuel. And general advice is to not use it unless you hate your car. From what I remember it clogs up stuff in the fuel system or injectors?  With US/Canada being E10 across the board, does that mean that all fuel there is terrible?

      Sorry, are coilovers ACTUALLY ILLEGAL in NSW? They aren't in Vic, as long as they retain 70% of stock travel and the car is above 100mm off the ground. Does NSW actually have a law making coilovers actually illegal? RWC/Blue Slip/Engineering people not knowing the actual f**king laws boils my blood. Demand them to point to the documentation that states a coilover is illegal. (it may exist in NSW ) Edit: I checked. They aren't. https://www.nsw.gov.au/sites/default/files/2021-02/RMS-infosheet-light-vehicle-modifications-manual-suspension-and-ride-height.pdf
