All alloy dohc 24 valve in-line 6 cylinder, 3239cc, Eaton Supercharger, sequential fuel injection. Aston Martin DB7 power plant so UK - given the engine was a Cosworth or Tom Walkinsaw Racing (I can't recall which)

[Sirpent]

Thank God you responded, I have been trolling the net trying to figure it out LOL

 

So, found one yet?

 

And what do you think about the AMG my learned friend?

[peter mc]

haha i am tuning one of them at the moment at work NZeder in a jag it is a monster

[NZeder]

Well it is your thread after all and I could not have you and other posting there guess in this topic now could I 

So, found one yet?

Well the reason this engine came to mind is a guy I know of here in NZ has just picked up one that is damaged and he is going to turn it into an endurance race car. I believe one he does plan to re-power the DB7 with much larger V8 that he has in his shed. This same guy also has a 260z 2 seater shell with a full cage that said V8 was meant to go into - so you never know what could happen 

And what do you think about the AMG my learned friend?

What an engine that is going to move a zed along very nicely indeed.

I can sense another project change coming on !

Thius looks the goods but too hard to find and too many $$$$$

Interesting conversion there John, will look forward to seeing how you do the subframe to strengthen the zed and what other chassis reinforcements you have planned. The engine looks cool and I am slightly terrified by the number of pulleys on it - I counted eight .

 

Are you still going with the G-nose look and out of interest can you change the chip/ecu to get around the top speed limiter if you wanted to take it out on the salt?

 

Cheers.

Hi Brab's

 

The subframe is going to be a heavy piece of kit, Im looking at running a ladder network along ecah side of each rail more or less encapsulating each rail in a rigid lattice if that makes sense, this will continue up along the inner side of each rail and colmenating at the front with a lower rad support cross-beam, I will use the original cross member mounts as bolt points and then have a new cross member fabricated that will attach at that point also and further back along the rails in the same way a benz cradle is mounted, this sub-frame will form a backbone which im hoping I can mate up to and bolt to the rear diff / supsension points, I really want this to be a bolt on job rather than welded in place in case I ever want to remove it.

 

Pulleys, yeah, well it's a single surpentine belt set up, and some are tensioners, I will be running power steering and air-con now but Im not taxed by the set up due to the massive space up front I will now have.

 

The G-nose it an absoluteyou can be sure of that, now I can plant a nice big heat exchange in there for the water cooled intercollers.

 

A lot of C32 drivers have had the limiter command negated in the ECU, but I will be running a different ratio diff so at this stage with the R200V 4.36 LSD diff I picked up and running hopefully 235/45/17 rim tyre combo the car will have a load of bottom end but top end in 5th even at 7000 rpm max speed would be 235 kph by my calc's, if I ran a high 3. then 300 would be posible.

 

Think 200 will be fine at this stage LOL

well done mate , you will have 1 of a kind there, cant wait to see and read more

 

If you need anything in sydney to help you please let me know

Thanks Bro,

 

May have to talk yto you about doing a bank job to pay for all this now LMAO

 

Seriously though,  I may need you to take a look at some small pieces I may need at some of the Benz importers in Sydney, for once I have to say that the guys in Melbourne are nowhere when it comes to even a simple phone inquiry.

anytime mate just let me know

[mossy]

Well there's some amazing engine conversions around lately, an AMG and a M3, looking forward to them both, good luck with it John.

[luvemfast]

Think you'll have to change your username to ibenZ 3.2

Look forwards to seeing it come together!

What way did you end up going for freight?

Well my chassis is stamped RS30 so now Im building an RS32 (32 for C32) I have a quote for freight door to door for US $1058.00 but I may give you mate a call.

John,

 

As I said on the phone, that car of yours is going to be right off the richter scale .. and if those gearing ratios and speeds are accurate, you're going to need a parachute to stop the thing (and maybe a fighter helmet & oxygen mask to drive it!). I followed Aaron's car at the weekend and that thing was stupidly fast, and thats a NA overbored L24.. Can only imagine what your car will be like! Having said that, this is from somebody who has not been in, or driven a 240Z since 1998!

 

So now we have an M3 and and AMG powered cars, just wondering ,, has anybody stuck a Ferrari motor into a 240z? Before shooting me, its not that crazy ... the early pre F-Inj 400i motors are not that hard to find, and are essentially based on the Columbo V12, famously used in the 250 series, and of course GTO, albeit in 3.0L capacity. There are lots of ferrari replica's that also use this motor too.

 

Anyway, distractions aside John, this car of yours I think will be pound for pound the most excting in the Country. Its great to know that so much time and money are going into these cars .. can only be a good thing for collectability, and values.

 

Cheers, and good luck with it John.

[Sirpent]

Thanks Adam,

 

I dont think I will ever push the car to its full potential, and it will be unique but then again so will Davids and numerous other cars on here all in our own ways just as yours will as far as originality.

 

Its not the speed although I love the idea of knowing its there if ever called upon, its the fact that you did it and can enjoy it first and foremost.

 

Cheers

Geez I got lot of catching up to do.

Still very stressful John.

Got lot more gray hairs now than ever before. In court round 2 at the moment. Once all finished ill post it all up so people know what to watch out for.

 

Its more than 12months since the dreaded day. Just been busy with all of it lately and keeping away from forums. 

 

Gets bit depressing seeing all u guys getting well into finishing the projects and I have to start from square #1 again. After depression goes away than motivation kicks in after reading some of the build threads. Can't wait to start the 240Z build but at the moment the Z32 Fairlady Z keeps me entertained.

 

Also can't wait to see your AMG monster in the S30 bay so when is the engine coming over?

 

cheers Johnny

[Sirpent]

Hey Johnny.

 

Hope all goes well, Im sure it will dont give up faith.

 

Engine should be leaving for Aus within the next week or so, however i hav been speaking to the engineer who will certify it and it's good news and bad new's.

 

Apparently new laws are about to be launched regarding modifications, its all to do with power to weight ratio's

 

I just got this from him today after he did some investigation, see attached text below, read page 11 as he specified in the email the go to the allowed capacity table for a supercherged engine. The dry weight of the 260Z is 2425 lb or 1099.961 kg  :-\

 

So anyone considering a major modification, should take note.

 

Cheers

 

John

 

Hi John,

 

Thanks for your call on Monday, please review the table in the attached VSI14 update on page 11.

 

http://www.infrastructure.gov.au/roads/vehicle_regulation/bulletin/pdf/NCOP3_Section_LA_Engine_01jan2011_v3.pdf

 

In the short term, prior to VSI14 taking effect in Vic, we can still use VSI 8 which would allow your proposed engine with significant engineering evaluation and reasoning, this would include re-enforcements to the chassis to achieve a v8 engined spec of torsion and rigidity as well as brake testing, lane change and all of the other applicable modification codes.

 

I am happy to take on this project if you would like to proceed, please advise,

 

Regards Paul

[benny]

what does the weight need to be "legally"?? Couldnt you just load up some weight for the roadworthy??

 

 

[Sirpent]

It states for a supercharged motor of 3.2 liters which is what the AMG is, and based on their calculation, it would have to be 1101 Kg's

 

You cant fudge it, it clearly states optional extra's such as Air Con etc dont count toward the weight, its what the car was rated at as standard from the factory in original state before any modifications.

 

Cheers

 

John

[NZeder]

So look at the later 260z shell data and use that as your basis - I think they come in around 1100kg dry.

 

see http://www.zshop.net.au/260tech.htm

 

so check dry weight 2425lb = 2425/2.2 = 1102.27kg so that comes at your requirement dry and it states that is for Australian/European spec 260z.

 

EDIT: hmm bugger just found the 100% true lb to kg I always use 2.2 but it actually is 2.20462262185 = 1099.961kg as stated

[Sirpent]

LOL Mike

 

Good try buddy, but Im thinking dry weight is less fluids or at least fuel?

 

Therefore, technically you cant drive a car without at least a few litres and that is a functional requirement as oppossed to an accessory, the tank in a Zed is 65 Litres, at a kilo a litre that would put the car at 1164.961 kg operational weight, think I may have found a technicality !

 

If Im wrong can someone please beg to differ? your thoughts Mike?

 

Cheers

 

John

[NZeder]

dry weight is usually minus all fluids ie water, oil, fuel. So the water and oil should get you over the mark + 1l of fuel to move the car

 

EDIT: on page 12 it states the following

should be based on the heaviest sedan version of the model (not station wagon version) sold in Australia.

So given the zed was available in 2 seater and 2+2 I read that as you can use the heaviest sedan version = 2+2 so that is well in as they are 2630lb or 1192.94kg

 

So then using the table that would be

1192.94 X 3.0 = 3578.82cc in boosted form or 5964.7cc in NA form

 

Does that help
