In terms of your spacers I was just speaking to a lad yesterday that had a Nismo, Mk2 mind you but he had loads of problems with his Eibach spacers. He changed to the Z1 Motorsport spacers with the extended nuts and he said it cured the problems completely. Also might be worth using some 3in1 anti-seize copper grease, will help them not get as stuck. Thanks buddy. Unfortunately the spacers are going to have to get cut off. I split a nut in half on Saturday by drilling down both sides, so essentially the nut was in 2 halves and it was still welded to the stud! The nuts are made from aluminium (and very soft aluminium at that, i managed to round one off with 1 hand!), which in hindsight is absolutely shocking from Eibach. Really not something you expect from a company with a reputation like that. There was plenty of copper grease on them and they were torqued upto the factory lug nut spec. They have just galled so badly from heat cycling! They were only fitted in January as well. I will probably complain to Eibach once its all sorted as these thing obliviously aren't cheap. When searching online for this issue, Eibach spacers are the only ones that come up, no other brand seems to have this problem. Either way @Adrian@TORQEN is sorting me out with some new wheel studs which should arrive today, as well a host of other new parts. Great service from them to pull me out the sh*t so quickly. I will post some pictures of the butchered spacers up for everyone's amusement when they're finally off. 1 Quote Link to comment Share on other sites More sharing options...
dave_7 Posted July 21, 2020 Author Share Posted July 21, 2020 In other news, additional fuel pump is here courtesy of @nissanman312, so i big thanks to him for sorting this out! Just need a few more bits and that will be ready for fitting and testing. All parts are from Protec, so should be no issues with quality. Short term plan for testing, I think I am just going to wire it to a 12v plug, route it to inside the armrest console and simply plug it in when at the track, before hard wiring it in with a switch further down the line. 1 Quote Link to comment Share on other sites More sharing options...

Looking good mate Mines been in a good while now and hasn't given me any issues and allows me to run to empty without suffering starvation Protec are having my car in soon to design a purpose built kit for the problem but for now that should keep you lapping on less than quarter tanks 2 Quote Link to comment Share on other sites More sharing options...

dave_7 Posted July 27, 2020 Author Share Posted July 27, 2020 quick update from the weekend. Took the garage i booked the car in at over 2 hours to remove the chocolate Eibach nuts, they are now destroyed but at least they are off! Raised the issue with Eibach and they literally couldn't give a monkeys! I wont be spending anymore money there thats for sure. Either way it meant I could fit the fresh discs and pads ready for Anglesey in a couple of weeks. Spacer are back on now with some proper steel nuts this time. Also checked my catch cans. They are certainly doing they're job and have stopped a considerable amount of sludge going anyway near the maf's or throttle bodies. Definitely worth while for anyone who wants to drive one of these cars hard. Went for a good 4 hour blast out round Wales yesterday as well (should have taken some pictures). Fuel tank is now suitably empty so i can attempt to fit the additional fuel pump over the weekend along with diff bushing, diff brace, subframe collars and engine mounts (a lot to do in a day but I'll see how i get on).

dave_7 Posted August 14, 2020 Author Share Posted August 14, 2020 2 part update today from a load of work i did last week. Part 1 is the home brew fuel starve kit to overcome the fuel starve issue on track, car currently starves on long right handers even with 3/4 of a tank and constantly refuelling through the day gets old quickly. Credit to @nissanman312 for pointing me in the right direction with this one and being on hand to answer my questions as obviously anything fuel related is more daunting that the usually job! Basically uses a low pressure protec fuel pump mounted at the bottom of the passenger side portion of the fuel tank to pump fuel from that side, over the hump into the tank and into the stock fuel bucket in the drivers side where the stock fuel pump is. Fuel pump is mounted to the structure inside the tank using cable ties with the filter as close to the bottoms as possible. Obviously doing this on as emptier tank as possible is a must. Submersible fuel hose is routed from the Protec pump outlet over the hump in the tank and into the top of the opening in the top of the stock fuel bucket, again held in position with cable ties. Bulkhead rated for use with fuel added to the top of the fuel sender unit cable routed through the access panel via a rubber grommet i added a plug at this point so i could split the loom without issue, if i ever need to take the sender unit out again and for now Ive routed some 4 core armoured cable into the the armrest and wired to a 12v plug so the plan is plug the pump in whilst on track days and i can unplug it on the road so as not to run the pump dry. when you plug it in with the engine off you can hear the pump whirring away in there so i know it work. the setup is basically what Z1 offer in their fuel starve kit without the hydromat and without splicing the power for the pump into the stock fuel pump loom (meaning its on at all times). I am on track day Sunday at Anglesey which will be ultimately be where i find out if this was worth all the trouble! 2 Quote Link to comment Share on other sites More sharing options...
dave_7 Posted August 14, 2020 Author Share Posted August 14, 2020 update part 2 is basically the fitment of: white diff bushing kit z1 rear subframe collars bell raceworks diff brace as expected, the diff bushing in the subframe was a bish to get out. 50mm hole saw, 8mm drill, recipricating saw and a big hammer. Took just over an hour for it to surrender. fitting the new bushing was a 5 minute job on the other hand. I lobbed them all in the freezer the nigh before so they all flew in. The diff brace was not as simple as its made out to be. I got it to line up just about but that's with the diff in loosely and all shafts disconnected, if you where to just over this up to your diff with everything bolted up you'd have some trouble I'd imagine. Also there is a nut with locating boss welded to it that is the top mounting point (not seen in the picture), which needs to be fitted from the inside face of the subframe which was a bit fiddly even which the entire rear end disassembled. Still very doable though. last up was the subframe collars, once everything is off the car these slip in nicely. Now obviously i can't comment on the difference all these things have made individually, but as as collective I am absolutely blown away by the difference they have made. I wasn't expecting to feel that much of a benefit on the road but the difference is staggering. Its a very difficult thing to describe but basically feels like you're right foot has a much more direct connection with the back end. You can pile the power on much sooner and at a quicker rate because the way its delivered is much smooth so unsettles the car less. Its also stopped the intrusive TC system kicking in at every opportunity because the diff isn't waggling round like a turd in a bucket. Honestly wasn't expecting the difference to be be this good but this has left me pleasantly surprised! A proper hardcore diff needs to get added to my wishlist now! 2 Quote Link to comment Share on other sites More sharing options...

Luckily, after much digging, looks like I may have them the right way round. Like we said earlier I am gonna manually measure the old bushing and compare to the new next time I am under the car. Then also change the diff oil and if there is any sign of metal shavings in it i know something is not right. I am fairly confident its is right going off all the digging I've done on the US forum but you can never be too sure! http://www.the370z.com/engine-drivetrain/100343-rear-diff-bushing-top.html On 15/08/2020 at 17:31, davey_83 said: I remember clearly the difference whiteline diff poly bushes made to my 350z, let alone all those other goodies. No axle tramp now chap Oh yes it has made a huge difference. Another thing that was noticeably better at Anglesey yesterday is when the car does oversteer and step out the feedback from modulating the throttle is bring it back into line is so much crisper. Real confidence inspiring stuff! At one point i even managed to catch a slide going down the corkscrew there, I will have to dig out the footage 1 Quote Link to comment Share on other sites More sharing options...
dave_7 Posted August 17, 2020 Author Share Posted August 17, 2020 Also additional fuel pump was a huge success, managed to run down to use over a quarter of a tank with zero issues! I am confident you could run it even lower if you wanted too. Make a big difference not only shedding a bit of weight but not having to top the fuel off after every other session. Really pleased with the outcome with it would 100% recommend for anyone else with the fuel starve issues! Quote Link to comment Share on other sites More sharing options...
Bry Posted August 17, 2020 Share Posted August 17, 2020 You should have dumped out the vlsd and put something a bit more capable in there. I know it's not cheap changing the LSD but it is the best mod (along with AD08R tyres) I've done. 1 Quote Link to comment Share on other sites More sharing options...

Its on my wish list but like you said not a cheap bit of kit by a long shot, do think it would make a difference though. The stock vlsd is not horrendous by any means but at the same time isn't great either. I feel it will become a must for me further down the line. Which diff did you go for?

Does it live up-to the hype? I have an OS GIKEN 1.5 way with 4.08 final drive and solid diff bushes. I found the vlsd very unpredictable and was often spinning up the inside tyre. I've never fitted an after market LSD to a car before so didn't know what difference it would make other than to stop the inside wheel from spinning up on tight turns. I honestly was blown away at how much of an improvement it has made. The car not only has much more grip, it is now so much more stable and smoother in the corners. It's difficult for me to explain but it requires alot less effort to drive fast in corners now and it is very confidence inspiring. Strangely it's given my car more front end grip too (no idea how that's possible?). I don't know what sort of witchcraft a good LSD does but oh my lord does it work . Wish you could drive mine for a comparison. I'm aware that after spending alot of money on a part, that most of us will convince ourselves that it was worth it but if the LSD I bought made no difference to the vlsd then I would definitely share that opinion. I think the 4.08 final drive will be a personal preference over the stock 3.69 as I didn't think the stock 3.69 was that low. After fitting the 4.08 fd I was pleasantly surprised as it makes the car feel more like a sprinter compared to a marathon runner.

It does sound like a big improvement and you aren't the only person to say so. What other suspension/handling changes have you made if you don't mind me asking?

Its a real shame they've discontinued the AD08R, as their predecessor - the AD08RS sounds a bit poo from what I have been hearing about them 100% agreed about the seat, i run a CG lock which is a big help but no substitute for a proper fixed back bucket seat. For me one of the main issues is going to be getting an aftermarket sear to sit lower than stock. I'm 6ft 5 so my helmet rubs on the roof liner. I'm not fussed about having rails so will probably mount directly to the floor pan as long as I can find somewhere to fab me up a sub frame. I have also looked into DIY brake cooling ducts, piping from cutouts in an aluminium under tray. Never got anywhere with it though. Car needs them though the dust boots in my calipers are toast and even after a cool down lap my brakes can still be billowing when i come back into the paddock 1 Quote Link to comment Share on other sites More sharing options...
Bry Posted August 19, 2020 Share Posted August 19, 2020 I have a bucket seat bolted straight to the floor so have heaps of head room (I'm a midget at 6ft compared to you).

dave_7 Posted August 21, 2020 Author Share Posted August 21, 2020 A few shots from last weekend at Anglesey. Awesome day and stayed dry all day. Only 30 cars allowed booked on due to currently local restrictions which meant loads of track time and only 1 red flag all day!! Also my undertray decided to commit suicide on the way there, so it was cable ties and duct tape to the rescue. Its only the access panel that cover access to the upper fixings (its a different layout to the other 370z undertrays) so I will just remove it for now but will be looking for an aftermarket aluminium one as the plastic one is crap. Unfortunately Z-speed are the only manufacturers who do one for a mk1 Nismo and the price is extortionate. I heard rumours that Z1 have on in the pipeline as they already do one for the mk2 so i may hold out for that. Failing that i will have to CAD on up and get it laser cut myself. https://www.z1motorsports.com/undershroud/speed-performance/speed-370z-performance-aluminum-undershroud-09-14-nismo-p-11891.html 4 Quote Link to comment Share on other sites More sharing options...
