I bought a genuine garrett gt3582r yesterday, .82 rear, 4 bolt. I also ordered a 6boost manifold and 50mm wastegate which will arrive in 4 weeks from today. My car currently has; Z32 afm, 910cc at 3 bar JECS injectors, walbro 341 fuel pump, power fc, tuning crap, hd clutch, 3 inch front pipe, stock cat, 3 inch kakemoto catback. I have the car really well tuned currently on the stock turbo at 14psi. No knock anywhere and nice afr's. So I'm just after advice on putting this setup together. I can assemble it now worries. More just after tips for tuning ie: more timing and less fuel down low to fill up the lag gap? And ideas about afm placement? I have read a bunch of stuff about afm placement and am leaning towards leaving it in the stock configuration. I'm getting some oil and water lines from ebay. Are these as simple as bolting in? I read something about a 20 micron oil filter for the turbo. Anyway any info/ideas would be good.

:cheers:

The exhaust will have to stay the same for now as I have already made the missus mad with my spending. Swapping the cat is on the cards. The exhaust will get replaced next year when the motor gets changed. Ebay lines are crap aye? Where's a better place to get them? I know a guy who works for enzed. I spose he could do it.

EDIT The engine internals are going to stay stock for 12 months so it wont be wound up too much. :whistling:

I am assuming the turbo intake is 4", if so I wouldnt put a 3" afm in the intake, too restrictive on that sort of turbo. Yeah as said above exhaust will be restrictive, both cat and catback.

hardly, leave it in the standard position, make sure your intake pipe has a bend in it and you'll never have any troubles.

as for tuning, same basic principles apply as with a standard turbo, you want a gradual dip from cruising afr's down to 11.5-12:1 at peak torque/full boost then 12:1 to redline and as much timing you can run without inducing knock or going past MBT

Kando dynamic do quality line kits for about $100. I would NOT call them ebay crap. Have used them myself in the past.

As for your setup, aslong as you have a decent gate (tial mvr or similar) and you replace that cat, you will be cool. A decent 3" cat is only $189, why skimp?

Also you did not mention an FMIC, make sure you have one of these too.

045how lol I still have the 2 stock turbos and the t3 flanges arrived yesterday. I still dont have the head flange yet. Seeing as the rb30 in my shed is getting stroked next year I was thinking about keeping the flanges and putting another gt35 on it. We'll see. Jonnohr31 The missus is getting to be a good co-tuner so it should only take a good weekend to get the tune 90 percent. R31nismoid I'll go see the guy this arvy and let him know what I need. Only 3 weeks and 6 days to go. I already told the boss that I'm taking a sicky to put my car together :laugh::sick:

I'll have a sus of the line kits today. I'm getting a turbosmart 50mm gate, its coming with the manifold from Kyle. Lol the cat will get replaced. I have a 600X300X100 front mount. Sometimes I forget the some of the stuff I have put on the car :wacko:

The actual hole in the intake of the turbo is only around 2.5 inches. Its just the outside fitting that is 4 inches. Also you say cat and catback need replacing. Yes the cat will be too small. However it is more important to have a larger section of pipe at the start of the exhaust rather than at the back. If I were to replace the exhaust in sections I would start from the front and work back. Eg: Disregarding the cat (cos its getting replaced), I'd replace my 3 inch front pipe first.

Everything in that setup is too restrictive for the potential of that turbo.

Its even too restrictive for a GT30R.

Not everything. The injectors flow 910 cc at stock pressure and 990cc at 4 bar. The afm is good for 360 kw or so. The intercooler is well big enough. I thinking about the future. I have an rb30 in the shed that I have almost ready to put with the 25 head and the missus and I have decided to get the spool 3.4 stroker kit next year. I have all the necessary bits on the car to make a stack more power except the turbo. Its better that I run this turbo near the low end of the efficiency range for now than flog the crap out of a smaller turbo that will get replaced in 12 months. Hey, I can afford to do up the car but I dont own a bank :whistling:

    • Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank.  In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine. I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied. Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice.  Goddamnit, I would really have preferred this not happening.  
    • Boot is going to be replaced eventually. I just wire brushed what I could and rust converted. Then painted in rust kill primer. the spoiler also got repainted and plugs replaced on the ends. The under side of the bonnet is going to be black also, currently white. But red on the top side, same colour code as the silo to begin.
    • Hi guys, has anyone either purchased or built themselves a rotisserie for their car before? I can only just justify the need for one hence why I should just make one but at the same time, if I make one I can kiss another 4 weeks of potentially productive car working time goodbye because I'm building a bloody rotisserie....  I mainly want it for the application of the body deadener.  Cleaning the old stuff off, priming and then colour over the deadener doesn't worry me, it's just the application using the Schutz Gun that I feel would achieve a significantly better finish painting it side on and keeping the Schutz Gun upright.  I don't think they would work well on the side let alone almost upside down for some areas.  If the product I use (Terosun, etc) could work through a HVLP ok then it might be ok to apply without the rotisserie.   I can get one of these style ones for about $1200 which is pretty good value-     I reckon if I made one it would cost around $500 but it's more the time that it would take is more of a killer than the cost.  They look to hold their value pretty well second hand so I could always sell it after using it and realistically only lose $200-$300 at worst.  Or keep it and buy another project when this one finally sees the light of day... Anyone selling one...? Cheers!  
    • While it is a very nice idea to put card style AFMs into the charge pipe (post intercooler, obviously), the position of the AFM and the recirc valve relative to each other starts to become something that you really have to consider. The situation: The stock AFM is located upstream the turbo, and the recirc valve return is located between the AFM and the turbo inlet, aimed at the turbo inlet, so that it flows away from and not through the AFM. Thus, once metered air is not metered again, neither flowing forwards, or backwards, when vented out of the charge pipe. When you put the AFM between the turbo outlet and the TB, there is a volume of pressurised charge pipe upstream of the AFM and there is a volume of pressurised pipe downstream of the AFM. When the recirc valve opens and vents the charge pipe, air is going to flow from both ends of the charge pipe towards the recirc valve. If the recirc valve is in the stock location, then the section between it and the TB doesn't really matter here - you're not going to try to put the AFM in that piece of pipe. But the AFM will likely be somewhere between the intercooler and the recirc valve, So the entire charge pipe volume from that position (upstream of the AFM, back through the intercooler, to the turbo outlet) is going to flow through the AFM, get registered as combustion air, cause the ECU to fuel for it, but get dumped out of the recirc valve and you will end up with a typical BOV related rich spike. So ideally you want to put the AFM as close to the TB as possible (so, just upstream of the crossover pipe, assuming that the stock crossover is still in use, or, just before the TB if an FFP is being used) and locate the recirc valve at the turbo outlet. Recirc valve at the turbo outlet is the new normal for things like EFRs anyway. In the even of a recirc valve opening dumping all the air in the charge pipe, pretty much all of it is going to go backwards, from the TB to the recirc valve near the turbo outlet. But only a small portion of it (that between the TB and the AFM) will pass through the AFM, and it will pass through going backwards. The card style AFMs are somewhat more immune to reading flow that passes through them in reverse than older AFMs are, so you should absolutely minimise the rich pulse behaviour associated with the unavoidable outcome of having both a recirc valve and an AFM in the charge pipe.
    • Yep, in my case as soon as I started hearing weird noises I backed off the tension until it sounded normal again. Delicate balance between enough tension to avoid that cold start slip and too much damaging things.
