Hey

 I’m new here so I apologise if this is the wrong section upfront.

i am considering new project cars and was thinking about building a V8 R32 GTR and wanted to ask if anyone has done it while retaining ATESSA and what engines?

If I do it I’d want to retain an Nissan engine and I can’t go past the potential of the VK56 based on performance and available parts etc from the US and as I know that the VH45 will fit I was wondering if anyone had or knows of anyone doing or mocking up a 56DE in a 32 GTR? 

The aim of the car would be to a fast a street car as possible which I will use in drag, roll and top speed racing events.

I am aware of the custom fab work needed and am mainly trying to work out first if the engine will fit along with a nice twin turbo setup along the lines of twin 6466 or 6870s.

Thanks in advance!!

i know you are going to say to be different but why? the fastest street, radial gtrs run tired old rb30 blocks. quickest so far is a 7.4.

what level do you think a vk56 needs to be at to be at that level.

Look up Project Unicorn on Mighty Car Mods (or it might have been running on their mcmtv2 channel).  They did VK41 + turbo into Stagea.  So same same basically.  Shows you what you will need to do.

Beyond that. I echo the sentiments above.  The VK56 is not an inherently super dooper strong engine.  The RBs were fairly over-engineered, but the VKs are much later designs where a lot of overdone speccing was cut out.  Then there is 30 years of dev work in even more over-engineered upgrades for RBs that is missing from VKs.  Sure, the bulk torque from a larger engine would be nice to have, but you can have as much power as you need to make it impossible to drive with a 3L anyway.

      Hello, sorry for being late to join the discussion, but my clock just died on me.   Ive tried to look at Michaels digital clock repair.docx and it doesnt work maybe the file has expired.   Please let me know if you can re upload it or take some youtube videos to show us how to get the clock installed? thanks

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Strange issue RB25DET wont start

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.
