Something twin charged, thats for sure. Looks like the turbo feeds into the supercharger, which looks like a factory unit, probs the one of the 4agze?? Or maybe they merge together, its hard to see.

Looks quite intricate though.

Im working on the merge collectors today and then onto the rest of the headers. I have holidays this week and I hope to get this part close to done this week!

Thats insane! Looks like it will rip some mean skids! Where is it located?

Here are the two merge collectors ready for vband rings, which I dont have yet...Anybody know of places that have 2.5" and 3" vband rings with clamps?

Got them expanded down the road at Macs Mufflers at Brendale! Did it while I waited which was good. Cost me $30.

Time to clean up the insides!

All the merge collectors I found that could be bought from an exhaust shop were not proper merge style ones. They were the old fashion way with pipes tacked together and a conical sheet rolled around it and then shaped around the pipes and welded up. I wanted to this bit properly and challenge myself....it did take the better part of today though. But it was my first go at doing this....surely thats a good enough excuse lol.

Good thing GCG has the vbands! Woot! Problem solved.

Actually I have done abit. I havent bothered with a proper update yet as I never got the exhaust finished. I have done the extractors and down to the 2 into 1 merge and left it at that for the moment. As of today I have the motor and gbox out and the bottom end stripped for inspection and a few mods and tweaks to be done before it all goes back together and then back in.

I didnt go into any detail in making the headers like I originally wanted. They are far from equal length and abit messy. It took ages to do and it was a pita. I couldnt make it equal length or close too like the UK guys did in their race car because I still have heater lines and wiring and other crap along the firewall and so had to place things differently. But as you will see from the pictures 1,2 and 3 go where they need too inorder to clear the intake and 4,5 and 6 basically go straight down into the collector. The other main hold up before coating is my egt sensor setup from america is being held in customs as it was over 1k :( I gotta fill out all the bullshit paper work and go pay the extra tax before I can collect. Once I get them I can weld in the fittings and paint the whole thing or maybe get it ceramic coated and then heat wrap it all and have it ready for installation.

The motor looked great when stripped down. I rebuilt it like 3-4 years ago and since then havent looked after it very well, gave it shit oil and hardly changed it. The oil that came out of it was quite black and burnt. Yet the bearings were damn near perfect apart from a few polished areas on some, but the majority were still with factory coating and discolouration. I was amazed as this car hasnt been treated very nicely when it was being used. Many burn outs and thrashings have been given over that time!

So I gotta do a few adjustments to the factory oil pump and then some new seals front and back, fit the twin plate, possibly modifying the std sump to hold a couple litres more oil, reassemble the bottom end and then chuck it in and finish off the exhaust and fuel system side and hopefully try and get it started! :D With any luck I wont have a million things to try and fix before it runs reliably.

Thats about all I got for the moment. Once I get a good amount accomplished I will post up a big one!

    • No intention of driving the car the way it's set up now, just wanting to make sure I haven't made any mistakes along the way so that the tune can go smoothly, I don't want to waste anyone's time with stupid issues. And of course I intend to get it towed to the dyno in a completed state 😅 I have the base fuel pressure with the vacuum disconnected set at about 40psi, which I believe is at least relatively close to stock fuel pressure, maybe I'll have a fiddle with the reg and see what happens. For all I know I could be wasting my time with this and I should just plumb it in and see what the tuner reckons. I just find it a bit strange that it seems to be under so much load just free revving, but maybe that's just a result of the turbo slowing down the exhaust gasses and making a restriction in the flow, with no boost to compensate.
    • The boy just hit up google translate and it worked a treat, he said step one was "please urinate with precision and elegance", he then sent me the correct translation  I get some new loctite for the small fixtures tomorrow and get some "dort" going after that 🤣
    • Right, so is the fuel pressure the same as it was previously? If not, well, it's not going to work well. I can understand the theory I assume you are going for, which is: "Run it N/A, and if I have the original AFM, and same amount of fuel and intake air as previously, the fact there's a turbo in my exhaust should still make it run" Which it... might? Provided you don't actually change how much air or fuel is going into the car.. or getting out. But if you have changed that, all bets are off. What is the purpose to even have the car run this way? To get it to a tuner? And if the goal is to limp it to a tuner, you're still going to what - plumb up a whole intercooler system and new intake in the parking lot out front before your tune......?
    • Haha yea it's a bit of a weird setup at the moment, just wanted to make sure I sorted out any headaches before dyno day. At the moment I've changed the exhaust manifold, turbo and downpipe, 460lph fuel pump and rising rate reg as well as the previously mentioned headstuds and gasket. The nistune was already mapped for the car as it was and drove around for a few months no worries. The plan is to run flex fuel hence the big pump, which I've wired direct to the battery through a relay to avoid voltage issues.
    • Um. Was the ECU the same as the one previously there? I know R33's needed R32 GTST ECU's or other tomfoolery to run Nistune. This is such a wild setup. Most people would plumb in the turbo then not drive the car (i.e tow it to a tuner). What's actually changed since it last ran?
