Anyone had any experience with getting and fitting uprated valve springs for a Neo head ?

Am looking for a full set to upgrade a head I am using to go with Tomei type B cams

Does anyone know if 2.6 GTR valve springs can be used or is it Neo only ?

Other then that have only seen Spool and Ferrea who list them as available , unless anyone knows otherwise?

As for Ferrea I see they list them as needing to be used as a kit, does that mean with using o/e valves or with their own valves also?

Cheers

From what ive read today tomei actually make a valve spring kit for the type b cams. A few people have questioned the quality of the japanese springs on past posts however and yeh basically recommend ferrea as you said and if it says use as a kit id probably follow what they say....if the heads off then may aswell.

Alot of people couldnt justify the need to change the springs, as the type b cam is a direct drop in and does not require such a mod (unless they are rooted or your running mega boost)

Yes the head is off and plan to have it flowed and ported as required

I would like the engine its going on to be able to run up to 8.5k rpm but don't believe the stock springs will run to that?

Not saying it will use all the revs but providing its safe to that then I rather change them

Certainly whilst its in kit form I want to change them now rather then kick myself later

Will have another look at Tomei springs as I can't say I noticed them for a Neo, only gtst ?

Yeah definatly, I agree id do the same and change them all while its out for sure.

As for tomei springs, went through my history and yes it was for rb25 ( not neo). However i came accross performance springs australia....heres the link may be some kind of help to ya ☺

**edit**

Those ferreas look the goods and by all the reviews ive seen its definatly what id go with when it comes to replacing mine. Whether its a little more or not, i wouldnt go cheap on springs..

      I'll just leave this quick tip here after reading your joys of getting the car in the air. It should take no more then 10 minutes to get the car safely up on stands.  So for the front, jack on the tow recovery points (marked in red). Put the jack stands under the lower control arm mounting point (marked in yellow). This photo is of a R34 GTR, however the process is the same. For the rear, jack under the diff (marked in red). Put the jack stands under the rear subframe or where the lower control arm mounting point (marked in yellow). Which point you use will depend on your stand, pick a nice stable point.  You've probably already read this but it's worth repeating. When jacking up the car or using stands, stay away from the chassis rails/pinch welds. Even the factory jack point, stay away from that too unless using a factory jack. I used those jack points for years without issue until I turned into an old man and bought a QuickJack lol.

      And this is where the leak is happening: https://www.dropbox.com/scl/fi/7h1vlmg2j5aa7rksvsjc9/IMG_9982.jpeg?rlkey=d3bnpau5f615zmxqmca0llvr7&st=kquvdxvs&dl=0   Apologies but it seems adding an image from a link does not work when the images are in Dropbox.

      Hi all, From the western suburbs here. Just got my 2000 R34 GTT registered today! Got it imported from Japan through a mate who is doing them and managed to find a decent one. This one has only done 110,000 Km and had no body rust etc. so was very happy. I used to own a 25Gt back in 2015 (ate Ramen noodles for years to save up for it), but unfortunately, it got stolen TEN DAYS after I bought it!! Came back from Uni and the car was missing - cops found it in Springvale a month later with a lot of needles  😒 It was too late by then and I had moved on to a different car (300ZX), and after that one got broken into around 2018, I was in a very bad place and decided I would never buy a car again because it was just pointless!!! ~yeah, I have some very bad mojo~ 🥺 But now, with a stable job and a secure garage, I thought I'd get the R34 4D again but not as a daily! I love the R34s but a GTR is still a bit off my pay grade so settled for the GTT instead.    The first step for me is to get this car serviced and have all fluids, belts and spark plugs changed. I might do the brakes at one point too but atm they are fine, the fluids are what I want changed since this car probably sat in a garage for a long time. I'll then get some coilovers since the suspension needs to be changed anyway (the dust cover kit is disintegrating). I'll also upgrade my car alarm to a Viper system and then look at rims and tyres (I'm a sucker for TE37s - might have enough saved in another 3 years for that).   Today: I was planning to do the oil, coolant, air filter and fuel filter change this week. Started on the oil change today and MY GOD what a pain!! I used to think the 300ZX engine bay was cramped - oh I was so wrong! 😂 I've done the usual services on my cars before so it was not like I was going in blind. I looked up all the forum details about what oils to use, what coolant to use, what points to use to jack the car or place stands etc but I did not expect it to be this hard. Long story short - all I managed to do was the oil and filter change. I think I might end up taking it to a mechanic for a coolant change because my SCA stands and trolley jack just can't get far enough underneath to the cross-member and I don't want to be crushed under my favourite car....yet. Side note: In Dandenong, there used to be a shop that lets you hire their hoists - does anyone know if they have those around? I can't seem to find the Dandenong place anymore. I contacted them off FB almost 6 years ago and I'm not in it now. If anyone know of one, that would save me some time going to a mechanic for the basic services. Oil: Dark and gooey but no metal pieces. Oil Filter: Was a b***h to take off but no red flags Air filter: Yucky! Was black (Smells like fuel which makes me think it may have been running rich? - am I way off?)   Concerns: I have but one concern atm and that is that there was a very small amount of oil leaking where the engine and the transmission connect (Automatic). It may be the rear seal? It's not a massive leak and it does not affect the oil pressures or leak oil all along the driveway. It's been falling into the cover this whole time. I've taken the cover off so I can check the garage floor from time to time.  I also have not seen my engine temperature gauge ever sit at cold and slowly move up to the right spot, but that might be because every time I saw the car today, it was running. I'll check that again tomorrow. ATM it just sits right in the middle. I may just be paranoid but I don't want an overheating engine while my gauges say everything is fine. 🙈 Other than that, I'm very happy with the car! Feels like it's about time I went back to spending my weekends driving or cutting my arm on stupid sh*t in the engine bay.   PS: I will post a pic later on because I underestimated soooo badly today and it was dark by the time I finished! PPS: I broke the two damn plastic pins that hold the intake funnel section to the front bar. This is the piece made to bring cold air to the airbox. The connection to the airbox is fone, but the two clips just broke off! Should I be worried? Anyone else done that?
