Yeah man Remember

Yavuz dyno is very conservative when I had 253rwkw it pulled trap speeds of 121mph

I'll come down and race ya!!!

haha game on! I'll let you know when im heading down.

The SS2 would be a very good turbo reaching close to the maximum of capacity of stock cam shaft. I'm looking to upgrade cams for the maximum capacity of some larger frame turbochargers that we build.

I'm looking at the Tomei Pon cams and the HKS in256/ex264 cams. Can any one whom used them share some experience in terms power / response behavior?

I've got poncams in mine, power and response are currently pretty much on par with your results with the G3, though I suspect I have cam timing issues holding me back so can't really draw any conclusions on the cams yet. They certainly feel ALOT better than the stock ones did, but given I changed plenum, ecu, cams AND tuner all at the same time; I guess that doesn't count.

Hurry up and dial em in :whistling:

I gained tonnes of response

That's pretty impressive for a bush core Stao, how does the brass help over the bronze?

The materials makes no differences. its about how and where the oil is dispatched and delivered. I'm working on another set of brass bearings that can possibly spin them selves with oil entry.

With the Pon cams I thought they are drop in which don't requires dialing?

Eh, not driving the car in this heat. New seats haven't arrived yet either, so I can't drive it at the moment anyway. I'll get it done sometime :)

And Stao, they are, but I did mine at the same time as removing the head. Head was decked when I had it reconditioned, so I lost some deck height. Wouldn't have thought it enough to throw off my cam timing, but it's a question mark so need to check timing and make sure.

My head has been skimmed a few times so was necessary. Unopened engine would be fine

What do cams do?

Beef up mid range or up top?

Tomei Poncams 256/256 should give a gain over the entire powerband (with an aftermarket turbo mostly).

If you went 264 - 272 you would then be trading low range power for top end.

Thanks for the response. Since most people are on stock cams. I will run through the evaluations on the Billet TDxx series before I switch cams.

Also I've built this last week for a customer that required anti surge sound regardless of power or response. lol. So I've tabbed some threads and made custom plugs for this housing. Anti surging now becomes selective.

Looks good Stao :)

Hopefully I will have results from the ceramic ss2 inside the next few months. Work is getting in the way at the moment but my engine is just about done

my SR SS1PU is at unigroup now.

am going to give them a call with some final instructions for how id like my powerband to fall so i can sit back and wait for the results.

possibly going to have to trade some of my top end for response though as im not running VCT. will still be a good indication for S13 type SR owners.

My SR SS1PU tune is now complete. Result was 235rwkw on 98 in todays 45 degree heat, 18psi of boost.

Unigroup noted the tune has been pegged back a little more than normal as the motor is brand new (no road time) and will be used for track only duties over the next 12 months.

They state it reached 248 with an extra degree of timing but chose not to push it because of the above mentioned factors, told me to bring it back once its done some actual road time and they can stretch it further but also mentioned its probably not going to be that noticeable.

Not bad for a 45 degree day, Im sure it will be a rocket. Thanks for the great turbo Stao.

Thanks for the feedback. Not bad for 45 degrees day, under a factory it would be oven baking. That affects the cooler's ability to heat sink. Also well, need more boost, still missing 6psi. :yes:

    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
