Jurgen-Jm-Imports Posted July 18, 2011 Author Share Posted July 18, 2011 Turbo is here and motor going in today or tomorrow so hopefully JP we can have the line up, real shame Jurgen won't be there as was looking forward to racing him as well, we are just having to re-enginneer as we found a rod just and I mean just touching the bottom of the bore. Hoping we can tickle the map on our dyno to save a day at TDI (its a whole day by the time its loaded and driven there and bolted on etc). But all told we are all set for Suprapod, Im thinking of giving TOTB a miss as the move is going to take priority.good luck with it.. i will be there in something thats for sure..maybes not to compete with you lot but it wont be something slow..

Pete Posted July 18, 2011 Share Posted July 18, 2011 Sorry to hear about this Jurgen. Out of interest, would it be a really bad idea to wire up the ignition so that if the oil pressure dropped the engine would automatically turn off? I guess power steering and other engine driven things would pack up... Link to comment Share on other sites More sharing options...
Jurgen-Jm-Imports Posted July 18, 2011 Author Share Posted July 18, 2011 engine is out of car... piston tops (no holes just a bit carbon on them) spark plugs all right colour.. almost impossible to see the cracks to naked eye.. we only have bell hosuing, engine mounts to block and turbos to remove and shes ready to go to japan.

Wez Posted July 18, 2011 Share Posted July 18, 2011 Really sorry to hear this matey, the build up was a work of art and I hope JUN do the right thing by you it was running 28psi at time and i even had a bit of race fuel in it too. What race fuel was it and does the stock ECU add/trim timing with higher grade fuel based on feedback? Link to comment Share on other sites More sharing options...

Wez Posted July 18, 2011 Share Posted July 18, 2011 c16 mate, yes ecu adjust the fuel mate... Were the dyno runs done on normal road fuel? If so I guess its possible that with the C16 in the tank the stock ECU could have trimmed fueling/ignition to give even more power. Link to comment Share on other sites More sharing options...
Bailey. Posted July 18, 2011 Share Posted July 18, 2011 Is the r35 block anything like that in the 350z, same casings etc??? Link to comment Share on other sites More sharing options...
CanisLupus Posted July 18, 2011 Share Posted July 18, 2011 Is the r35 block anything like that in the 350z, same casings etc??? I doubt that. The 350Z Block is AFAIK originally from Renault and is also used in the Espace V6 the GTR was developed by Nissan themselves just for the GTR Link to comment Share on other sites More sharing options...
Bailey. Posted July 18, 2011 Share Posted July 18, 2011 Worth a try, I know abbey motorsport have made some crazy power for the project zed car, sure it's not a street car and the maintenance would be crazy but just wondered if they could be worth a call.

Chris Wilson Posted July 18, 2011 Share Posted July 18, 2011 Is the r35 block anything like that in the 350z, same casings etc??? Similar design, but strengthened I think, (although insufficiently for Jurgen's needs ). AER are getting great power and reliability from the 350Z based N/A units, now over 500 BHP, which is pretty good for an engine based on a 3.5 V6 road car's castings: http://www.aerltd.com/products.html Link to comment Share on other sites More sharing options...

JamieP Posted July 18, 2011 Share Posted July 18, 2011 Some powerful 350z's about, they are no GTR though. Link to comment Share on other sites More sharing options...
Chris Wilson Posted July 18, 2011 Share Posted July 18, 2011 That's crazy chris. And expensive.... Their little 4 cylinder Mazda turbo MZR-R is a work of art and one my favourite engines. I think they pull a reliable 650 to 700 BHP unrestricted from it, and you can pick it up, fully dresses ready to run. Link to comment Share on other sites More sharing options...

Guest ugp Posted July 29, 2011 Share Posted July 29, 2011 1100bhp for how long though? Any updates on this? Or haven't they got the engine back yet? Link to comment Share on other sites More sharing options...
Chris Wilson Posted July 29, 2011 Share Posted July 29, 2011 Give `em chance It would be a very expensive thing to air freight back, it may be going over the water and take ages. Link to comment Share on other sites More sharing options...
Miguel Posted July 29, 2011 Share Posted July 29, 2011 Jurgen, have you come across any decent photos of these block failures? Has no one band sawed a block up that's failed (or even one that's not) and had a look at the casting structure? This sort of thing fascinates me and I am over at Engine Developments soon, who have people there who design endurance race engines from the idea stage through casting design, crank and piston manufacture, prototyping, development and on to Le Mans track side support. Whilst they do nothing for free I am sure I could get a few people to voice an opinion if they had some proper evidence to consider. Even if you just get high resolution photos of any external block damage, it would be interesting. People seem to mention oil and water spurting out, which obviously suggests the crack has been through both a water jacket and an oil gallery. These are often near engine mountings.... Might be worth a chat with Iain Litchfield, I believe he's band-sawing a good block up to see how it's cast. Link to comment Share on other sites More sharing options...

JUN Auto Mechanic 3-1-7 Sekimachikita Nerimaku Tokyo Tel 81-3-3920-4165 Fax 81-3-3594-2689 Aug 1 Dear Jurgen How are you? We took the engine apart. The conrod and wet liner were destroyed by the big power and big torque. We make the new engine considering such a big power. It will have finished in Sep 22. The delivery will be Sep 26 by DHL.
