wow, I think that mota & car build might be a bit more involved than mine lol Have gone for the motor only on mine as tbh once this is built I plan to leave it be Famous last words ... As it is I've got my mota built up and in the car, but am now waiting on getting the exhaust manifold modded Hopefully I will get sorted soon

Am using a Neo GTT head on a Spool RB34 build but with S1 R33 gtst loom. Its all but done wiring wise apart from this coil loom To run the matching neo coils ive picked up a S2 coil loom and changed all but 3 of the wires over to match the S1 loom All of the other wires colour matched fine apart from these odd 3 Hopefully you can see I'm left with these 3 odd wires to join below ... 1x black with red? tracer in the 2 pin plug from the S1 loom 1 x black/yellow in the S1 loom 1 x black with grey spots in the S2 coil loom Q's are ... Is the black with red tracer just an earth as that is in the same 2 pin plug the white power wire was in? Does the black/yellow connect to the black grey spots or are they also earth wires Hope this makes sense to you guys ... cheers

You don't need the little spring stop stud so just unscrew it.

Can I ask where you got the manifold and price ? Has it a RB25/26 universal flange and T4 ? Can't tell by those pics Cheers Spent the day reading through the whole thread again. What a bloody roller coaster. It's been a little dead in here so time for a bump. EFR 8374 1.05 ass end. 6 boost twin scroll manifold. 38 mm Tial gates will be used. Still waiting on those guys (talk about lead time)

Cheers for the info

Hi Does anyone know if the RB20DET upper cam belt covers all interchange with other RB20 motors ? I have one in metal from an R31, but unsure if it straight fits RB 32 or 33 engines, or all the same anyway ta

You can get upgrade springs over there from Spool for a Neo with titanium retainers Should do the trick no ?

Sweet, thanks for the info n pic !

XK, How does the 2.6 get away with only the one feed and the other blanked ? Angry, From what I gather those running hydraulic lifters (GTST head) need to retain a larger oil feed to keep the lifters pumped. A Neo being solid lifters doesn't require as much, aka RB26 style feed with one blanked

Ok cheers, guess knocking 2 new restrictors in should do the trick- I hope lol Angry, am using a Neo (and retaining vvt) head on a 3.4 bottom end with Nitto pump so plan to blank the rear and 1.5 in the front

The motor I've received looks like they've been removed, so can someone confirm 100% if the 2 factory 2mm oil restrictors in the upper face of the block have any sort of check valve in or below them to stop the oil from flowing back when the motor is turned off? Are the restrictors just pressed into empty oil way feeds with nothing below them? One site says yes and must not be removed, but am also told nothing below them so no problem if removed and replaced?

Hi if known 100% ok am interested if you can send us a few more pics But first could/would you be able to deliver it to a garage in Berkeley Vale, 2261, NSW in person in with that price ? If so can send payment no problem btw, what yr car was it from? cheers

Cheers for the info It was actually a few posts I read on here a while back that got me thinking but they didn't go into detail as to why As for the head I am looking at valve springs atm just to see who offers what. Yes I will be using uprated springs (and cams) so if that's the issue then the problem shouldn't occur Red line would be set to 8.5k with a GT35 until I decide on a more suitable turbo

Out of interest what are you guys with modded R34 Neo heads getting them to rev to ? Only ask as read a few posts about them flipping shims out at high rpm ? What the cause is I don't know but anyone had any experience of this or know why they do this? Just poor clearance or that's what they do ? btw do they just run flat if this happens or damage the head/engine ta boot Alternatively if it is a problem can they be converted to shim under bucket - GTR style n parts ? Cheers

Cheers yes it might be ok but as its going on a high value engine build I rather not chance it now Last thing I need is for that to fly apart at high rpm or shake the nose of the crank off Not to worry as Spool are now kindly looking into the cost of a new part, only they are right out of parts normally given away Go figure lol

Thanks for getting back to me Yes sorry I found your reply in the wrong folder So you're basically saying tuff - its not your problem and you don't feel in anyway accountable for its damage ? Even though I purchased the part direct from you and you shipped it, it's still not your problem ? Sorry chap but yes I purchased the part from you - not the mail service - so I feel it is down to you to sort out ! But what you are saying though as I read your email reply is go ask Spool to order a replacement part and they then foot the bill on their account !! You are some piece of work mate, that just shows how honest you really are fa sure ! I advise anyone who wants to buy anything off this chap to think twice And if anyone thinks I am making this up then I will happily post Shoota's reply to me btw, It's not to shame him at all either, just get the facts out there so others don't come unstuck Make of it what you will

Hi I sent you a pm and email earlier but have had no reply so hope you see this message The balancer you supplied has turned up at Spool as requested but it has sadly arrived badly damaged It looks like the box you shipped it in was in no way suitable, as it is clearly been bent from being dropped or knocked I guess ? I have added a few pictures for you to see. These are exactly as Spool sent them to me. You can see in them there's just a little bit of bubble wrap around it so suspect that's why As I'm in the UK its a little hard to call you else I would In the mean time can you pm me your address so I can ask Spool to send it back to you for a refund Obviously its of no use to me like this and I rather not risk it on a high value engine build I'm sure you would feel the same if the shoe was on the other foot Cheers and hope to hear from you soon

Cheers, yes have emailed them to see if they suggest they are suitable

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 ?

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

Payment sent, cheers

Scratch that, option 2 - you have pm

What's your best price shipped to the uk mainland - balancer only required Can pay paypal straight away no problem if its a good quote

Cheers, what are you guys using coil wise with the Neo head ? Matching Neo coils or adapted Gtst coils? Car is using S1 Gtst electrics so still runs a separate amp Only I've have a set of as new Nissan OE Gtst coils and although haven't tried it looks like their mounts are all out ?

760 at the wheels? So over 800 at the crank as a standard head/ports and valve sizes? Cheers I will have a look for the thread. Am using a link g4 and have a aftermarket crank damper so I assume it will be compatible ?
