Hi Guys,

Just wondering if anyone has recommendations for places to get some machining done, either in Sydney or Wollongong. I need to get the surfaces machined on my exhaust manifolds and the tongue removed on these Greddy/Trust split front/dumps....

Speaking of which, those of you who have used the Greddy/Trust extension pipes with turbos that already have a exhaust/wastegate split, how much did you have taken off?

Cheers,

Lucien.

lol

I had this thought when looking at the 34 N1s next to some seperated dumps. as your SS have the same exhaust housing as the 34 N1s with the integrated seperator I would take it all off.

Yes, I was thinking just to have the tongue machined flat. However, looking at the exhaust housing on the HKS's, the split finishes about 5mm from the top. I was just wondering (out loud) if its worth leaving a mm or two of the tongue sticking out of the front pipes for a closer fit. Obvious issue is that the metal is going to expand when its (very) hot...

yes, i thought about that too, but i think it's fine (and safer) to leave that little gap.

Yup, again, agreed, but thought I would throw it out there in case some wisen old sage knew better. I wonder how disruptive to flow having that gap will be? It interesting to note that there is a gap of about 1-2cm in the divider at one end on the exhaust housing to allow gasses to move from the exhaust wheel side to the wastegate side.

SW20-GT: Thanks tosh, I will call them tomorrow.

If anyone has any other recommendations, fire away.

Depends on the turbos you have. If you have Hks GTSS's then just machine the lot out, thats what i did . I must warn you they are a bastard to fit on .... and you cant fit the turbo brackets on them either .

Yup, they are GT-SSs. I assume you mean have the tongue machined off the dump/front as opposed to machining out the exhaust cover.

I'd be interested to hear anything else you have to say about installing the GT-SSs (I was going to post a question about it anyway). By turbo brackets, I assume you mean the turbo support braces/brackets? Do the foul on something, or just not fit period? Any solutions/recommendations (or any other thoughts)?

Thanks :rolleyes:

Thanks :P

I assume you have a 32 gtr. If you are going to fit them on the car i dont know how hard it is but it wont be easy . I have fitted turbos many times on a gtr with engine in the car but never thses bastard dumps ( they are a bastard let me tell you ) . I fitted them on a 34 gtr but with engine off the car and with gtss turbos all i did was machine off the tongue of the dumps flat then bolted them on the turbos . When i tried to assemble the engine the o2 censor ( rear dump) was in the way of the coolant and vacium tubes so i had to mod the tubes to fit them on !! Depending on where your rear dump o2 bung is you may have to do the same too .

If you have a good look at your dumps you will see there is no place to bolt the turbo support brackets and unless you go to a lot of trouble to make some different bracket you cant bolt them on .

The best solution ? Sell them and use HKS dumps , they are a direct bolt on job and eveything fits on .

The other thing you will find is :The rear dump ( that bastard again ) will be touching your air cond discharge hose, if you leave it on it will melt it in about 5 minutes so make sure you remove it and replace it with a copper tube ( a bastard of a job on the car after you find out it touches ) so do it while the turbos are off the car and you have plenty room there .

The only advantage with these dumps, the front pipes are very easy to fit on !!

If you need to know anything else feel free to p.m.

Have you talked to Nath about the machining? He can help you out, he has everything in house

No, it never crossed my mind he did this sort of thing in house? Thanks for the tip. I'll get on to all the recommended places on Monday; got distracted today :D

Just for those who are searching for info on the above, I have posted a reply here:

APM in Albion Park seem to do some pretty great work.

In case you didn't see in the post I linked to above, thanks for the recommendation to Oak Flats Muffler Men. 4PM on the day the Queen's birthday and they got the job done a treat :O

    • That is correct. I'm using a modified ABS ring and a ZF speed sensor on my rear diff for speed input. I'm running a Haltech ecu. 
    • Been busy with the newborn. We originally thought we were going to go for a third, but we're good with two lol. He's starting to actually sleep now so I've had some energy to work on the car. It's been parked away in the garage since late November due to winter.  I went ahead and redid all my head oil drains. I originally had my front and rear head drain going into the same pipe but have since split them up. I also added an Ethanol content sensor to get ready to run E85 this summer. Tossed it on my return line. Sensor sits nicely under my intake manifold.    I also have a lot of parts that came in for my rear end. I'll be swapping over to a 3.3 final drive and doing the GK teck anti squat mod. While the rear subframe is off, I'll also change every bushing. We're planning on buying another house soon with the condition that I get at a minimum a 2 door garage, so I'll wait to have more room for this. Now onto the strange things that recently happened... After changing the lower rad hose (It had been sitting in my cabinet for well over a year and was the last hose I had to replace), I let the car idle in the garage to bleed my coolant. After running for a few minutes, it started missing. Got much worst within a minute or two and then stalled and would not restart. My crank sensor decided to crap itself. No damage, no explanation, just died. I went ahead and replaced it with another ZF sensor but the heavier duty stainless model with a shield. Tossed that in and started right up. Has anyone else seen this? I hate when things fail without cause. Luckily this was a blessing in disguise... This lead me to recheck my timing. It seems I may have had a beer or two the last time I had set my TDC angle as I was off exactly 5 degrees... I miscounted a line haha. I was running 5 degrees less then commanded. It's a little embarrassing but helps explain why my dyno operator seemed to think I should be making more then 478rwkws.        
    • Sharing results from recent Liberty Walk R35 GTR, since they are still considered as somesort of a V36 Skyline. We do them turbos too. This are high flowed SS-1 models with ball bearing conversion done.  Car have managed to pull 485awkws @ 20Psi so far pushing limitations of factory built engine. The build list for R35 GTR enthusiasts as follow : HyperGear high flowed stock turbos in SS1 (G25-660 specs) Custom titanium intake pipes. Vspec performance titanium front pipes. Vspec performance 4" titanium exhaust. Upgrade fuel pumps. 1200cc injectors. Ignition coilpacks Hks intake plenum. Hks intercooler piping. Greddy intercooler. Greddy bovs. Top-secret coolant reservoir. Emtron ecu. Straight E85. Built gear box.  
    • Nah no bearings, just slip fit.  Would be a reasonably challenging but not impossible job to modify it to run bearings but I'm hoping that's not necessary as I may have well built one myself if I end up spending hours modifying it!
    • Brumbys with good shells are bloody expensive, I've looked at 2 "cheaper" cars, and walked away from both,  plus after some research spare parts are fairly sparce I'm starting to think that I missed the boat on finding a clean one that is straight (ish) and without alot rust I'm starting to think about a old Hilux as panels and other parts are much more available as they sold tens of thousands of them I use to be indecisive but now I'm not sure
