Converting back to L24, need info please

[auz]

hi guys,

after a lot of searching about converting a 240z with a l28 back to an l24 I decided that I should join this forum so I can get definite answers. From my searching so far I haven't been able to find out what would have been done to the wiring in the car to suit the l28. It would be extremely helpful if one of you guys were able to list the alterations/new parts that will be needed to convert back to the l24.

I know someone will want to ask why, the reason is the two 240z's i've been looking at to purchase over the last month have both been converted to an L28 and as I will be on p plates and an engine swap is not permitted.

thanks in advance

Welcome, has your Zed got some EFI?

engine swap is engine conversion no, you can have a L28 in a 240z as they came out with one in that body in the form of a 280z not zx so long storey short it is fine to drive its only when you convert to a non standed engine where it becomes illegal for p platers

the wiring should be the same unless fuel injection or electronic dizzy has been added, possibly different carbys other wise the engine is the same externally far as I know,  the only way you could tell them apart looking at them is the engine number, one will be L26 ****** the other L24******

Edit:: you blokes are on to it my old fingers are to slow

oh that is great news i was almost 100% sure i had to convert back to the l24, i will look further into this thanks heaps.

Just double check nobody has modified the wiring at the alternator just in case they fitted the alternator from a 280ZX also..

if this is the case in nsw are you aware anywhere on the rta website where it says the legalities of this because I have been searching but can not find anything about a latter model engine swap on p's on their website

The L28 was available in the S30 in the United States called the 280Z.

The L28 was available in the S30 in the United States called the 280Z.

 

And was a hoologated option with the FIA for all 240 and 260 shells for retro fitting, how this would go with the RTA I don't know....

Here it is mate: http://www.rta.nsw.gov.au/registration/downloads/vsi/vsi_06_-_guidelines_for_light_vehicle_modifications_nov_2007. Its the first part on page 2.

However, if your a Red P plater you cant drive anything "modified" for performance" http://www.rta.nsw.gov.au/licensing/gettingalicence/200707_p1.html. So, putting an L28 in your Zed id assume is up to interpretation if your a Red P plater i think.

I haven't had any issues with mine though. They don't even realise the engine isn't standard at all.

yeah all this is fairly contradictory because on another section of the site it says a p platter cannot drive any vehicle with engine modificationsthat require a engineers certificate and then in what you sent me it says no modifications and then the guidelines for modification don't have an issue as it is under 20% increase, as well as the fact that people say its fine as it was offered in that chassis.

[DTF260]

Yep. I went through the same problem.

Like I said, the cant tell the difference between l24/l28 so you should be fine

[gav240z]

The engine is the same overall, it's just an L28 is bored and stroked.

 

However since the S30 stamped body came with an L28 from factory in the United States and was called a 280z. I don't think an L-series engine swap should require an engineers certificate. In my opinion (remember this is just an opinion), it's no different than changing a camshaft over for a different cam profile.

 

It's the same overall design and dimensions, it mounts in stock position. There is no reason why your L24 could't be bored and stroked to 2.8 ltr internally making it the same as an L28 and nobody would even know.

 

I would say you would be very unlucky to be picked on for this issue if pulled over. But take the risk as you see fit.

 

 

[PB260Z]

Gav makes some good points the one that really stands out is RISK.

 

I agree you are unlikely to have anyone pick the L24 - L28 change in a roadside check, the danger would be if something went wrong. A major accident involving personal injury could result in an investigation and then the L28 may be spotted and that could have an adverse impact on your insurance.

 

Just my opinion but insurance companies are always looking for ways not pay

 

Cheers

when i was in my p's i swaped a L28 into my 260z and just had the rta change the engine number over, all i had to do to get this is goto a blue slip station and get them to right me out one with tje new engine number. i always got pulled over and my car was registered with a L28 in it and had no issues what so ever, also on a plus side you can legaly put a rb20det into a 280zx with out a engineers certificate if you use factory mounts as both power is under 25% increase and there are no stuctual modifications needed
