Rusty Nuts

Hope you have a shed load of modifications to suit that MEC R280 Mines ECU

Search igniter wiring on this forum there are 32 pages on this subject. Read the knowledge base FIRST then ask questions. Your previous questions about your ride started you off on the wrong foot.

Why not a nice bit of straight road surely you could feel the timing being pulled.also( Maybe the guy on ebay posts to NZ)

Only other info I have is this part can be used on following chassis types ENR34 ER34 HR34 GC35 GNC35 HC35 WGC34 WGNC34 WHC34

Haven't got Parts catalogue for yours but by comparison its the same including mounting bracket

Part number 223705L300 from memory they are about $85 which is stupid. Nissan call them Tank Assembly-Pressure WTF

Its the vacuum storage tank, on the N/A R34 used for opening the variable length intake

Yep, there are two, the most common ones used are Part No. 2206059S00 they are used on multiple Nissan engines RB's and VG's. New between $160 and $180 but grab a couple from the wreckers, take one of yours as a sample. I'm running RB30 ones in my 25/30 and ecu is happy. There's a pair for sale on ebay for $14 the guy is in Bundaberg gotta be worth two schooners.

Sorry typo above. Should read 8/89 to 11/90

I'm assuming nothing of the sort, regardless how the tuner is listening its the output of the factory knock sensor that is signalling the ecu to pull timing

I know of no difference between Rb26DTT and Rb26DETT its just a reference change by Nissan after 1991

MEC R280 also from BNR32 8/91 to 11/94 Rb26DETT

MEC R128 belongs to a BNR32 RB26DTT 8/99 to 11/90

The knock sensor is tuned to detect the engine knock/detonation frequency, when they shit themselves they detect other frequencies as knock. Your tuner is hearing noise which is possibly fooling the sensor (and him?)

Mate, don't discard the faulty knock sensor suggestion. Search this site for Faulty Knock sensor there are eight pages of issues experienced , some very similar to what you are experiencing

Once came across a Neo that had a lifter bucket that would "cock" slightly in the bore and jam a few thou low which caused the lobe to slap hard against the shim. Changed the shim and it stopped doing it. The old shim had a substantial mark on it.

I agree with Angry RB the noise from mine was generated at idle only, But I had a spare engine and swapped over VCT.

Have you tried replacing the front knock sensor they rarely go wrong but shit happens.

What other solutions would I have rather than paying $1,200 for a gear from Nissan? part No. 132025-5L301 should be what you need. Available from AMAYAMA approx $854 14 days delivery but run your vin number to be sure. Mechanic told me the previous cambelt had not been done very well, and had likely been overtensioned. So this rules out the cambelt or any related tensioners to it, but could reinforce the idea of the cam gear being the culprit?... This statement set the bullshit meter to high. The camshaft sprocket rotates on a substantial journal which is how the VCT moves it. It is more likely the VCT internals are making the noise...they are not rebuildable

they are different part numbers so regardless whether they "fit" material used is probably different Nissan don't allocate two different part numbers for shits and giggles. R33 3970573L50 R34 3970573L00

R33 bottom hose part no. 2150372L00 R34 bottom hose part no. 21503AA000 . Not interchangeable.

R33 top hose part no. 2150175T10 R34 top hose part no. 21501AA000 . That would be your answer right there.

If your local Nissan stealer doesn't have one Partsouq have heaps in stock.

Nissan bearing No. 32273N4862 should include snap ring, change last number to a 1 snap ring not included.
