A local friend of mine is looking at selling his engine conversion in his 240Z and asked me to see if there was any interest on this site. Bascially the original cross member has been modified into a box shape to fit around the large LS1 sump. There is also a mount for the 6 speed, and no doubt a 6 speed to R200 tailshaft. This would certainly make the job very easy for anyone looking at doing this conversion, as you can imagine what it would cost you to hand your car to a shop and say 'make the fit in there'. He is getting some pics to put up soon but if anyone would be interested please let me know and I can put you in touch with him. Ideally he would like to sell engine and gearbox (in great running condition) with the conversion. He is still deciding on a price atm.
cheers

Yeah it would be everything for a full conversion, exhaust too I suppose, exhaust, headers, intake set up with pod out the front, engine gearbox mounts, wiring, computer, engine, gearbox, clutch master cylinder adaptor, rip shifter, tail shaft etc.

Ok pics are in. These were taken just after the engine was installed so obviously everything is a bit prettier now with the radiator in and intake piping hooked up etc. This conversion is a bolt in affair. With this package and an S30 you could do the transplant in a day. Keep in mind this conversion has been fully engineered with a mod plate in QLD.

Included is:
air filter and intake pipes(stainless)
Radiator pipes (stainless)
Radiator and thermos
computer and harness which has been base mafless tuned and has been made plug and play for conversion (between 250 and 300KW ATW) 
engine and box (LS1 T56 6 speed done 100 000kms came from VX clubby)

cross members engine and gearbox which sits engine as far back and low as possible and does not require tunnel mods. will bolt straight up to standard body and has had control arm mount holes moved up for better control arm angles and better handling, this is something the engineer who signed off on wanted an made me have a bump steer examination to prove it all safe and got it passed.

full exhaust, custom extractors into twin 2.5  with cross over pipe
tailshaft to suit the 240z and R200 long nose.

Brand new clutch master cylinder, and plate adaptor to use standard 240z clutch pedal and hole in fire wall and use ls1 master

if buyers want the fuel system it might be available depending how much they want to pay, and if you want injected or carby, its a 1200hp turbosmart pressure reg, fed by bosch 044, all fitted up using speedflow fittings and hose through a surge tank. cost shite loads just in fuel system.

There is more i'm sure but there is a good list, ill have more recent pics tomorrow. all the fabrication of cross members, exhausts and intake stuff cost over 5k. motor and box cost 5k and havnt even started on wiring and tuning and thermos.

At this stage he is looking to see what offers he gets and may even be heading down to Brissy soon so he could arrange delivery down there.

looks good, but i hate to be a pessimist here, went to the local engineer last year to do a v8 conversion for my zed and current QLD rules states that you can only fit up to max of 5L engine in S30 (4.4 to be exact plus safety factor due to monocoque contstruction which bumps it up to 5L in total). How did the QLD engineer approve this with LS1?
will the mod plate or proof of approval (statement from engineer) be included with the sale? be interested to find out :)

Interesting, this mod plate has the S30's serial number stamped on it obviously but I'm sure the actual paper work will be included. Ken (who's selling this) had an engineer work with him through the whole conversion to ensure he wasn't wasting his money the whole time so if there was ever a doubt this wouldn't have happened. This also isn't the first LS1 in an S30 in Aus.

What are the reg's here in melbourne?  Same as QLD for V8?  I am still interested in doing the V8 conversion and getting a "bolt-in" setup certainly has it's appeal.   

Happy to go through the process necessary with an engineer (already found the right guy in melbourne for this sort of thing), but wondering "how hard" it's going to be to get this LS1 through?

Engineer mentioned there were some limitations.  I thought 5L was the max. also.

Hmmm....

Is it something to do with needing bigger brakes to overcome this or is it purely chassis strength setting capacity limitations. Surely some of these RB engines can develop more kw than a standard LS1?

Being approved to fit an engine of LS1 capacity is all to do with using the heaviest S30 in the calculations - think about it.  However, as has been mentioned here, you need to fit appropriate braking capacity and you need a very sound shell to start with. It ain't cheap. but wow what a car.

It is also critical that the powertrain in correctly aligned... it's not a matter of simply plopping an engine in the bay.

Peter is right Mick. not ls1. from memory i think its gen4. 6L like RB30X sugested.

i did see the car in person and got few pics of it. fits nicely very nice neat job..... credit to the owner.

now for those that like chevy in their z this looks like a very easy way out. pending price i guess. think of it as 1 weekends work instant power increase.

good luck with the sale.
