does it feel like its going as hard on 14psi as it originally was?

with 244rwkw it should be spinning in 2nd and some of 3rd with the big phat mid-range this turbo produces

It felt great at 14psi but i have been told my my mechanic that it didnt feel like 244rwkw at all... I havent driven it since i had the problem as i didnt want to pick the car up if it wasnt 100%

In my opinion it feels great (but i havent drivent anything to compare it to), and pulls hard but deinatley wont spin 2nd unless i really abuse it and never 3rd no matter what i do..

What sort of power did yours make??

i made less than yours.. 231rwkw

i have 255 tryes on the back with 80% tread.

if i come out of a round about in 2nd and stomp on it they will spin from 4000rpm onwards and i get some spin in 3rd but not much...

really scary at first because it would come on boost rapidly and push u back into the seat...

apparently the dyno my car was tuned is a bit tight and there might be an extra 8-10kw in it but who cares.

I dunno, i did a dyno day in shoot out mod without touching the car from the 244rwkw and it made 211rwkw (35 degree day) and then yesterday he put it on the dyno (non Shhot out) and it made 200ish, then 220 with a touch of the tune and 16psi...

The difference between the 244 rwkw and the 211 to now is, i just had injectors installed and a Z32 AFM and an EBC...

Im only having trouble with the addition of Injectors, Z32 and EBC with more boost... The only problem is that i wont hold the 17-18psi it is given... It hits 18psi then drops strainght back to 12psi, anything more than about 14-15psi and it jsut drops off...

Previously i was running 244 rwkw witrh the stock injectors stock AFM and no boost controller with the stock nissan actuator

Hey Silva33, can you post a pic of your dyno graph showing us the drop in boost?

'I'M HAVING A SIMILAR PROBLEM' but my turbo is alot smaller similar to a 2530 but still i believe it should hold more boost then what is doing currently.

Garret T3/T4 A/R0.60 Compressor i think the rear is a tiny 0.58 turbine.

200rwkw@5000rpm peak 1.0bar of boost and down to around 10psi at redline

210rwkw@5000rpm peak 1.30bar and down to 12.5psi at redline.

running a avc-r boost controoler.

here is my graph

Damn you just beat me to it I was reading thru all the posts to make sure no one had already suggested it!

I once had a split in my silicone connector for the FMIC and it was the same problem as you were having.

It can be hard to tell with all the induction noise and revs etc.

you keep looking for more boost and it is doing it, its just not getting thru to the inlet manifold.

well done.

    • Did this end up working? Did you take some pictures?
    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
