Stagea Part Numbers To Share

[skidkid]

Recently our S2 Stagea shat a head gasket. I thought I would share some part numbers, tappet clearances and tips from the big job. Our wagon had only done 80k km. It would ping ever now and again. I supose it was bound to catch up with us. Engine was missing front head dowel when removed?! Once I got the head off I match ported manifolds to head. Took it to machine shop and it only had to have exhaust seats cut. They also blended the 'seat to port' factory machining steps. Planed head surface (min.) They adjusted tappets. They supplied an ancilary belt set and a set of NGK BCPR7ES spark plugs (I gapped to .8mm). I went the 7's for now to help with no detonation. We decided to buy 100k km service kit upon inspection. Used genuine nissan parts. Included t/belt, ten., adj., water pump, t/stat and cam seals (c/o Kudos m/sport). Gen. nissan VRS (Kudos). Gen. nissan head bolts (Kudos). I used ACL Hylomar on gaskets. I had injectors cleaned just cause. I fitted a Greddy ex. gear at same time. I decided to fit a new rad. when I found the replacment was 25mm thick compared to 16mm. An extra fitted while off the road is a set of Whiteline sway bars. Also have had a dodgy TPS for a while and am changing!! We are half way through a 2 week wait for it to make its way over from Japan on the slow boat!?!?

Tappet clearances I found (NEO engine) were: Ex. .014"-.016", In. .017"-.019"

Anc. belt numbers are one of each. 4pk0890, 4pk0865 anda 4pk0910

Tensioner & idler numbers on boxes were: 60TB0732A & BT-10513, 56TB2801B01 & BT-10529. First number of each was hand written.

Gen. nissan 82 deg t/state: 21200-V7206

Gen. water pump: 21010-AA527

Gen. PCV rocker cover gromet: 11051-5L300

Gen. VRS: 11042-AA525

Gen. TPS: 22620 AA509

Keen for TPS to turn up so we can drive and go get a tune using Apexi AVCR & Apexi Multi Checker. The wagon is going to get it once it is tuned!!!!!! Happy boosting!

Sorry to hear about your RB woes. BUT, it sounds like you're fixing it the right way.

Hylomar = goodness, I don't build engines without it.

Good work getting all the genuine Nissan part numbers for the benefit of all!

Hope it all comes good in the end!

New TPS turned up on thursday, only took 1 week. Fitted it after tea thurs night and took for a drive. No different!!!!! Had wagon checked twice, back before christmas and was told TPS was faulty. Today I checked TPS volts via Apexi avcr and multi meter, back to back (old verses new, closed 1.1-1.3v, open 3.95v) NO real difference!!!! With ignition on, but engine not running I can hear what sounds like a soliniode (spelling??) or relay humming that varies in pitch (not a click). Down on hands and knees it sounds like it's from down lowwer half of engine/ auto gear box. What the 'fruit tingle' is going on?? The idle will vary when it wants (cold or hot), won't change gears properly, not at all or varyed rpm shift points (tiptronic auto), steering and diffs get tight backing out driveway. Car will serge mildy on cruise. Wagon had these symtoms prior to head gasket fix so I believe I haven't caused problem. Help needed asap as we are really over it and wife wants to go boosting!!!!!!!!!!!

TPS wasn't problem. ECU stuffed. Vi-pec being fitted next week. I had air flow meter out yesterday to measure up for adaptor so I noted number. I want to keep air box. No. is; 22680 31U00, A36-608, E60, 8X17E.

Damn! I would've recommended a Nistune price-wise, but I guess there may have been something else in there which was busted that didn't get replaced. Having an intermittent problem REALLY SUCKS, as I'm sure you can appreciate by now... must be bloody fantastic to have finally found the issue though (and I hope you have!).

So the Vi-pec really can handle the auto's then? Let us know how it goes! Oh, and do you have a series 2 (NEO) setup, with the tiptronic auto?

[skidkid]

The tps was getting eratice volts from computer. We sent it away but it coulnd't be fixed. I have been assured Vi-pec will run our S2 Neo tiptronic auto. If not I am going to hurt somebody!!
