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:

    • Looking at the photos, you could easily just drop this pipe and dump into atmosphere  Just 1 or 2 quick hits for data acquisition - if have a heat shield material and/or sheet metal, maybe just use wire/metal cable ties and attach it in a way to deflect heat from melting nearby wires.

    • Yes, well, keep in mind that the air is intake air, which equal boost + possible oil. If there is a fine deposition of oil/scunge that then gets hot and carbonises, it could look just like that. Probably shouldn't be leaking. Might just be normal for that product. Hard to know if it is relevant.
    • Wrapped up putting the motor back in today. I have a stainless flex turbo drain pipe like you see on cummins and that funny enough PRP started selling. I generally prefer these but sadly they come with a finite amount of times they can be bent before they snap. Took well over a week for a replacement to arrive.  I was able to prime the pump but I will more then likely wait until next friday to take it on its madden voyage. I also installed the nozzles for my direct port WMI setup but plugged the nozzle holders for now. I'll tube it with Swagelok SS tubing and fittings next chance I get. No rush, i'll be breaking it for a week or two anyways. 
    • I could definitely do some logs without the VCT enabled for sure. I believe we tried it on the dyno and it still spiked but wouldn't hurt to try again and have the logs    I might be able to use some metal cable ties and hold the gate open entirely, I'd need to see about that one.   What do we think about these marks on the cap of the actuator? This is where the two parts push together where the diaphragm spring is. To me they look like air has been sleeping past?? Specifically talking about those black stains above the lower rim/lip. They can be rubbed away as if it's just an exhaust stain.
