Will attempt to make the scanner work tomorrow. Spoiling by 3. Full boost smack on 4. Change to the big can actuator should knock off 300ish rpm. What dyno is your 420nm at? Mine made 428nm stock turbo.

boostworx's dyno dynamics. i did 250kw at the last willall dyno day with a reported 670nm torque at the engine which i was told would be 400 odd

my car is very much stock as I have to keep it legal for the sake of it being my daily. i dont hold any delusions of being a wicked track driver/drifter, I just like the way it runs esp when i do a nice spirited hills run. thats the main reason im after response really... cant care about track times or dyno figures at the end of the day. at most id be using the car for advanced driver training to make me suck less. cause lets face it, nobodys perfect >:D

-D

i dunno eh, these buggers spool from 3k and im getting 275kw/420nm torque at the wheels.... some fine tuning to the boost controller remains as well as cam gears but eh, its more than enough for a non-rambo daily driver like me

I'd like to compare his powercurve to mine. Single vs double with only 100cc engine capacity difference. Would be interesting...

-D

Here...have a look at one of mine :P, from almost 2 years ago :unsure:

It wouldn't be easy. But I think Full Race have manifolds to suit.

legality is put before performance in my case (sadly)

the 2860 series are certified as after factory replacements and can get thru regency with ease

thats the other bonus - what makes those other turbos more special than the 2860s or the hks equivalents?

-D

Edit - this is my dyno sheet from last dyno day. Since then the head gasket has been replaced and all the associated plumbing (along with a good $1600 of troubleshooting at boostworx after the engine was reassembled - not just engine mind, entire fuel system and 4wd... long story, dont ask...)

With the 6258 I'm looking at 2871R power with response on par if not better than a 2860RS.

Throw in some cool shit like investment cast stainless exh housing, Ti alloy turbine, billet comp wheel, built in boost control and BOV, dual ceramic ball bearings in steel cages, huuuuuge internal waste gate, and a couple other rather cool things for not much more than what a 2871 retails for, and it starts looking like a winner.

yeah i bet that all costs a bogload. and some daisy blue will defect me for it

i reckon the 2860-5 is the best option for my situation. 90% street driving (hence response wanted, as well as legality being a priority) 10% driver training at lala (330kw from the -5 is supposedly easy to get, that is >plenty< for me)

-D

Edit - And to put in proportion, 330kw is what the last Ferrari Testarossa put out - I was a child of the 80s and base my power figures upon said cars :)

I guess in a TT application prices would start getting a bit silly. $3400 for turbos. Which isn't too bad, but then you'd need manifolds...

For me though, it's great. It fits on the standard mani and clears p/s, a/c, and engine mount bracket. Exhaust will be difficult because of how close the exhaust v-band sits to the engine, but that's a problem for someone else. :)

Mostly street and hills, occasional track. Response will likely be better than I had before. As for Regency... Meh. I have a daily. And it's just one more part I'll have to swap out.

And that is the dilemma. I've seen 2860-5 kits for $2k atm including the 14psi actuator, which means I can sell my N1's and actuator for around $1500 (which is what I paid and considering the car has been offroad for 6 months since I fit those n1's, they're barely run in.) The exhaust housings and sleeve bearings of n1's arent tops for performance, but they are legal. Just need to find someone who'd be happy with the close-to-300kw setup (i reckon they could get to 290kw with proper split dumps and front pipes), As it is, theyre doing 275 on a 21 yr old engine. 2860 -5 should be fine, unless the -7's are responsive enough. I just dont know.

-D

Yeah... Price difference is due to the fact that the BW's are a clean sheet design that has only hit the market in the last few months, 2860's are 20+ year old architecture. Once they become a little more widespread, the price will drop significantly I reckon.

As it is, I think I'm going to be the first SR in Australia running one.

Is the $2k price brand new? If so, that's pretty f**king reasonable.

Yep. $2500 from most places but I know a joint that does em for $2k on our current exchange rate, including 14 psi actuators. I'm still running the stock gtr actuators and a profec B

If they can get an engineers cert that theyre a legal swap in replacement, I'd hit it within a heartbeat. But I cant afford nonsense with the authorities so Ill aim to get the 2860-5s in 2 yrs unless those ones u quoted can be accepted

-D

I paid $1250 deliverd for my 2860-5's with actuators from the US :) they are laggy as hell, full boost at about 5000rpm.

are u serious? tt application? I thought -5's were less laggy than the -7s ?

Maybe I should stick with the n1's.. they are so goddam awesome to plant the throttle and just hold on for dear life

-D

When are you on full boost with the n1s dohmar? I need to decide what will replace my stock ceramics and I'm happy with my power level (250) but I want response. I'm spooling 15psi at 4500rpm upwards dependent on weather.

around 4k on full boost - it hits max boost very very quickly. if you're happy with ur current setup then u should buy my n1's when i upgrade heh

-D

Sounds like a plan. Just have to n1 spec everything else now. Might keep my aircon though

definately. if you're running a streeter then maybe u should cross notes with me, cause its been my MO for the last 4 yrs since I bought the R and somethings have worked well and others havent. max performance but only when legal is the MO. putting braking and handling before any engine mods mind you,

I've done a load of things that I've had planned for yrs. It comes down to practicality and the amount of $ u got to get rid of.

    • 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
