Well Ill try the ghetto boost mod to ensure the wastegate isnt creeping open (drill out the holes slightly).

3000rpm is pretty damn good to have full boost!!!

It looks like Im getting about 9psi by 3800rpm in 2nd.

Running a bit rich and probably not optimum ignition timing so maybe I could get thatdown to 3500rpm..

no, you don't drill out the holes.

I got a cutting torch and spot heated a bit of the actuator and bent it one way about 45 degrees, then spot heated another bit along the rod and bent it back the other way..... then bent another bit back..... Kinda like the ASCII 'art' below....

PS. Ignore the . look only at the lines... :O

you can drill NEW holes in the end of the rod that attaches to the flapper. I actually tried that......

But boost was, hmmmm, how to I put it....... VIOLENT! :O

Boost was miles to quick to come on and the EBC couldn't regulate it.

so I changed back to a more moderate ghetto mod :(

IMO i would go and get yourself a decent EBC,for piece of mind,

Bass full boost at 3k is bloody good.I have poncams and still full boost isnt untill 3800rpm.

Mine is a Precision BB highflow,shafts and wheels not balanced inhouse like GCGs but the cartridge(wheels and shaft) are sourced from Garrett already balanced.That is the only difference that i can see.

Cranked boost up to about 13 or 14psi. Can get that boost by about 3800rpm in 3rd. 2nd is about 4100rpm.

Not reving it past about 5000rpm but boy does it feel like a shove back in your seat as it comes onto the higher boost.

Cant imagine what 18psi +tune will be like. Currently running very rich.

You do have to get into the accelerator a bit more though with this turbo to make things happen

Forget about the lag - It's not really an issue - I think Im running about 13-14psi. I can't believe the hit it gets

Be careful if there is any wetness on the road. These cars are monsters. 3rd gear.. 3000rpm boost building. about 3800rpm steps sideways as it hits builds to 14psi!!

Not going to push it anymore till injectors then tune. Seriously though anymore than 240rwkw for the road is just plain silly :P !! Whatever its making now running as rich as buggery is plenty

Well I guess the 170rwkw it was making before at 10psi on stock turbo was plenty also hahaha

Increase grip. :P:D

I also have a vg30 turbo with r33 hi-flow front..Dont know much about it but it made 235rwkw at 10-12psi.

Ive recently converted the car to manual and taking it back to get retuned..

This turbo comes on really aggresive i love the feel and shove it gets, cant campare it to the stock turbo. Midrange couldnt really be tuned as Im only using a safc.

theres some old threads about this combination of turbos if yous arn't aware, that person had great results also.

Cheers

Hi Sloutch,

Here is the link I was refering to, good read.

I was extremely interested in the thread as I have an unknown turbo on my car and its seems to be a similar one in the above thread.

Cheers

    • 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
    • OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:
