So running high boost is living in the past now, well let's see how my new old style TO4Z goes with 25+psi rammed down its guts, I think I'm going to enjoy living in the past.

On topic, my old stock turbo ran at 14lb for 12months, when it was pulled off (pulled off he he) it was fine, just luck or regular servicing ? Maybe a bit of both, I was expecting it to blow so I upgraded to a China spec, it was good for a while but hit its limit of around 300, now I'm getting a T series which should keep me happy once some lbs has been thrown at it.

I know boost needs to go down.. Not my question..

I'm curious as to why considering Other people have had no dramas at 10 without a tune..

An curious to why after putting an exhaust on would it have effected my boost?

PHYSICS, letting your exhaust flow will reduce backpressure thus letting your turbo spool more freely.

More boost=you need a smaller gap on your plugs, if its coughing at high rpm try reducing the gap to .9 and see if that helps, maybe you need more fuel ?, take it to a tuner and check it out, its the only safe way.

How does the exhaust affect the actuator tho? That's what I'm trying to figure out.. Plugs have been gapped. Changing coils an ebc next week then I will be sending it in for a chip I'm sure this will solve the problem :)

      Man, different parts but the same numbers is terrible @dbm7! And it doesn't help that most online shops don't list the part numbers at all. They just give a list of compatible models...

      Slow when hot could also be because its getting more dynamic compression, OR things are getting a bit tighter once it is all expanded. If it were an earthing issue, typically I'd expect you to have it have issues all the time. Unless it's really a combination of both things. Where the higher compression, and things being a bit tighter, is giving that bit of extra load and you do need a slight clean up on the cables/connections.

      Yeah, this is one of the most annoying things about nissan part numbers... I've got an unrelated example... Image is of the AT output shaft ~ they have the same part#, but clearly the shaft on the left is beefier design to that on the right ...the difference (essentially) is the 'lighter' shaft on the right, is for engines up to RB25DE (this includes RB20 variants) : the shaft on the left is for RB25/26DET(T)....are they interchangeable? Yes...but obviously one shaft is going to be stronger than the other...and, the lighter shaft is around USD115, but the heavier shaft closer to USD150...same part#... ...epc-data usually tells a tale ~ the amayama listing for 39100-23U60 has a note "Longest side is between 60 and 105 cm" ; no such info is there for 39100-23U70 ...and given the great disparity in price between the 2 parts, it makes me at least curious (to the point of caution) where the 'extra money' went? ...ie; these 2 parts have a cost difference that (to myself at least) isn't explained by 'plastic boot'...ie; with amayama there's AUD700 price difference ...plastic versus rubber?...I'm not seeing it like that...and 60cm ~ 105cm...??...that's a huge disparity....something hinky going on here... I'd try searching by VIN, not model... /2cents

      I don't know for sure, but I'd expect them all to be interchangeable given the diff end and hub end don't move/change between any C34 series. Often Nissan will change part numbers and the aftermarket follows those year ranges; but the original part number change doesn't mean other parts won't fit. The change could be a change in material, internal parts or even just supplier. For example, all the RB gearbox to engine bolts are no longer available and there is a new part number instead. The only change is they went from cadmium plated bolts to zinc plated due to the issues manufacturing with Cadmium. They look different but work the same.
