350Butcher

Just tried to be helpful and weight stock disc vs the pfc floating assembly's I still have kicking around for but the stock disc (from a spare upright I built my brake kit from) is JDM size! It gives you an idea though, standard JDM disc 296mmx24mm and much larger Brembo size pfc disc 324mmx30mm both weight 7kgs! If the car is lowered and quite a handful over rough and undulating roads I can highly recommend installing these, made a big different to mine now its not bump steering all over the place when the road gets choppy when pressing on! http://www.splparts.com/spl-pro-front-outer-tie-rod-ends-370z-g37/ Read the "note" on these down the page, worth knowing in case you do swap wheels at some point

Good to get rid of as much unsprung weight as possible, does make noticeable difference to handling and chassis performance Cant speak for the Z1 discs but I’ve run pfc discs since owning my 350’s, reduces a massive amount of weight over standard items, well worth changing to. Not cheap........but is anything good cheap........would be nice for a change eh!! Its also the reason I run the 18” lmgt4’s.........heavy wheels feel like dumbbells in each corner and over bigs bumps you can feel the dampers struggle to control them.

Agreed.........sometimes you want to snatch 1st to take hairpins as 2nd isn't quite there but I think the 3.9 makes 2nd so much more usable in tight stuff rather than screaming in 1st or bogging in 3rd. As we now know you're only 15mins down the road you con have a run out in mine and see what you think before going for it yourself Think you'll be happy with the results........it gives way more than it takes from the cars performance and the driving enjoyment/experience

I installed a 3.9FD in my HR 350z at the same time as installing my lsd and its a great mod! I do a good amount of track days a year and wanted the advantages for track work but also use the car on road and for large trips for hols so was a little bit concerned about the negative effects it may have on motorway cruising etc but I think the 3.9FD is the perfect choice for the type of use I do with my car. (As do Nissan as they installed the 3.9 to the Nismo 370z models) On track it pulls through the gears noticeably and usefully quicker and allows you to keep the engine in the higher revs and in the power more of the time........I felt when on track the car was regularly bogging down in gear and waiting for the engine to pull through on every track from Cadwell to Nurburgring! For road use I don't feel there are any down sides at all to having this installed over standard FD, motorway cruising is at slightly higher rpm but even driving to the south of France and doing whole tank of fuel with cruise set at 90mph never bothered me at all so it's in no way as full on as "like being in 5th instead of 6th" Installation wise, I installed mine myself and it really isn't a difficult job for anyone comfortable with taking a spanner to your car and definitely not £000's of pounds worth to get done by third party! 3 bearings/ 3 seals a new crush sleeve and your chosen FD is all you need to get the job done. The hardest part is tightening the pinion nut onto the crush sleeve as its got to be tightened till the pinion requires 5nm to rotate (from memory.....check the FSM) and this requires a special and expensive gauge to test as you continue to tighten. (I ran down to a local transmission guy with £20 and he was happy to help with just this part of the job and with me borrowing his gauge.......top man!). I reused the same shims either side of diff and on pinion and when it was all assembled, backlash and pinion/crown wheel mesh checked it was perfect! Maybe I was lucky..........maybe the tolerances that Nissan manufactures its FD's to is plenty good enough. Obviously I can only give my view on the 3.9FD but I would say its perfect for fast road/track car and 4.08 would be superb for a track bias car but bit tiring on motorway runs if you do do the odd x000mile road trip. If you're installing an aftermarket lsd I think its a no brainer to add a new FD to your shopping list

It is a very well engineered engine, it’s a pleasure to pull apart and reassemble! Things have moved on since the D and E type big cats I suppose but I’d love to build one of them up and go for a drive!! Thats definitely the target..........should be 100/litre fairly easily (I say carefully), 370 n/a hp will suit the Z really well. Then all that’s left after that is to put the car on a major diet to raise it ability in every aspect..........but that’ll have to be on my winter 2020 plan!

Cool! Sadly I can feel the slow brigade are slowly starting to build and choke up n ruin them all just like they have in Surrey but they're still plenty to enjoy for the time being. Will do.........think there will be a delay now while I get everything ready and find some time for assembly again.........glad you're enjoying reading it as I have enjoyed sharing it all on this forum!

No problem.........will definitely keep you posted and sort something. I'll swap you a few laps round Donington for a passenger ride to sample your nearly 500hp Z! 15mins down the road!......Few nice roads from you out towards Nuneaton!

Managed to just nip out to garage to finish stripping down the engine................before nappy and cuddle duties call!! Rods all out and good to see the bearings looking in good nick then undo in sequence the retaining bolts a really nice touch is that you remove the external bolts and then relocate them into a threaded tapping that then presses the two sections apart!.........Like that! then all that's left is to lift away the crank! Again good to see main bearings looking good and everything spotlessly clean as I bought the engine imported from Japan with no paperwork or proof of mileage etc......always a bit of risk attached to that. Being a bit of a nerd I love the machining and engineering involved in the steel inserts into the ally Loosely bolted the sections back together again, covered up to keep protected and clean before running it all to the machine shop to get all that side of work done ready to begin reassembling into something hopefully pretty special! Hollow engine!.......

Happy to have you come along, say hello and see the car............hopefully we don't get 6months of salty roads this year/next year and I'll be booking something up again from March..............I'll post up what I've booked on to as and when Yes, I'm in Warwick............where about's are you?

Thanks very much!! Its a VQ35HR engine......same blocks, I have a new VQ37 crank in the loft, and I get to have a spare pair of HR heads buying this engine. Other upgraded parts I've ordered for it I've now added to the bottom of that post.

Thanks very much guys!

I did get a bit of time on the spare engine before my girl arrived.................when I popped the front cover I was very happy with the condition of the engine, no signs of poor maintenance with all totally clean castings........so a good start! The common oil gallery gaskets have started to fail though! Kept going, pulled the heads and bores look good, removed the sump and nothing but super clean and good base engine to rebuild up into my new 3.7lt screamer!! Have placed my order for all hardware for the build.............so final spec will be VQ37 86mm crankshaft VQ35HR Brian Crower ProH2K rods (ARP 2000 bolts) Customs CP 96mm 12.5:1 pistons spec'd with - accumulator grooves, - double pin oilers, - anti detonation grooves, - X forging - Ceramic crown and Moly skirt coatings - 9310 steel pin upgrade Also adding.........for full rotational balancing OS Giken STR2CD clutch kit ATI super damper crank pulley I'll carry over my current upgraded heads/cams and all other upgrades

So after a 9 month wait a very special, 8lbs2oz delivery arrived! All the Dad's on here will know how amazing it is when your little'n arrives............very special time indeed!

Good choice of tyre too..............love a fresh set of Yoko AD08r's!!

The above kit is what I have fitted to my HR 350z, very good kit with oem level of progression and bite but is worth noting the pedal weight is increased quite a lot in case that's not your thing............or if you share the car with your mrs! (can I say that these days!?)

I actively avoid these sort of keyboard discussions that seems to be the end of every post on this forum these days regardless of the original question or reason for thread but can’t help but respond here. I thought I made a safe assumption as your post was not in line with someone who uses heel n toe technique As for evidence, I can’t help feeling you provided it all in your last post

Paul W, that does all sound normal and as others have said, would be great if you could share some pics as it sounds like quite a project youve taken on there and I’m glad you’ve saved the car from a different fate. Sorry to do off topic. Ekona.....you clearly don’t heel n toe yourself as Daves right there. Factory lazy throttle paired with heavy flywheel makes for easy smooth shifts under normal driving as revs don’t drop when you depress the clutch so you can swap cogs no problem. Under more enthusiastic conditions and you’re standing on the brakes and blipping throttle to heel n toe you need fast response to give flare of revs to sync with the down shifting / heel n toeing. So remapping to a more 1:1 ratio on the throttle and paired with a lighter flywheel/clutch assembly will give you just that.

And the Corsa will get on to all of the straights quite a bit faster than a Z with that spec and there’s just not enough to make up the difference and then pull it all back too Obviously as stated at the start that driver skill will ultimately decide who’s quicker but if both can get the maximum from their cars in question then I’d still pluck for the Corsa over a lap

Think I'd put my money on the Corsa for this one. Those tyres and brake pads will cope far better with the lighter car and the weight saving will be a bigger advantage if its wet. Hanger straight is long but the little Corsa should come out of the Maggots/Becketts complex quite a bit faster so I don't think the Z will be able to rein it back in. Happy to be wrong...............and I hope you guys have a great time finding out!!

Sorry mate, stalking you today! Really like your Z Totally agree with what you’re saying regarding the rear and for me it’s the way the line over the front wing continues down the front bumper and with that front splitter element it all looks proper race car rather than showy, I can’t even say I like the styling on the Mk2’s onwards as it’s all choppy and a bit pony for me. Each to their own though obviously!

As always Davey, cracking pics of yours on this thread!

Mk1 Nismo looks so good.....like the silver/grey too as they all seem to be white!! Wheels work so good with it. Shame they’ve gone the way they have with following model as it doesn’t look a patch on this. It’s the one I’d buy if I ever part company with my 350

I’ve just seen the thread title below this one in the “videos” section and I’m already feeling sorry for him! Brace yourself mate!!

Well I’m glad everyone is enjoying this thread I started and we’re not all pulling things out of context or anything!

Evo magazine have always given the 350-370z 4-5star ratings..................HR 350z made Ecoty at release in 2007
