Shoota's R33 GT-R RB30/26

Valid question....  I've got the parts here to make up an AN10 braided drain hose but having had a brief look at where everything sits it could be tricky. I'm thinking I might end up using steel pipe at least for the top half of the drain until it's passed the manifold. 

Something similar to the pic below. Not sure about the flex baffles in that one though. I feel they might slow up the flow too much. But then again once the lower part of the baffle has oil in it the oil should just flow over the top. Beyond my intelligence level to know for sure!

I’ve just made a steel one for my eBay manifold lol haven’t even tested it yet and going to put it on tomorrow just so I can get my car up into the drive. Then I’ll strip it all apart again In preparation for my sinco. but there’s no chance my drain that I just made will fit around the sinco wastegate pipes. Re fabbing shouldnt be too hard just a pain I have to do it again. Shouldn’t have put an eBay manifold on in the first place ! 

Looking at your pics, you might get away with a 30degree fitting if not a 45 straight off the turbo and around the gate pipe. 

Ps that flexible pipe, what’s it called?

That is pornographic

You've done well, good on you for having a crack at it!

I would call that stuff a "baffled flex joint".  Google that and something similar should come up. 

[Shoota_77]

Got the lower section of the dump pipe fully welded. Did it all in one go so I could set up the back purging once. Pain in the arse to do it multiple times.

Some great welds, some shit welds and plenty of ok ones! As long as none of them crack in 6 months then they're all good welds!

Just waiting for the new flex joint next week then I can finish off the top half of the dump. 

Only one tiny straight section of the wastegate pipe to cut and prepare for welding then that will be all done too. Should have all of the exhaust finished by the end of the week. 

Almost over cutting, grinding and welding....  Cracked the shits tonight because I was over it! Nearly kicked some shit but managed to pull myself together ?.  Finished off the section that was shitting me so all good now. 

Next job will be remount the intercooler and start making the intake piping. More cutting, grinding, welding....

 

[mr_rbman]

what gas lens do you use on your tig and what flow rate typically?

[Shoota_77]

@mr_rbman just using a cheapy Ebay gas lens.  I think the cup is around a 7 or an 8.

Generally running around 12-15cfh gas flow.

The thing I find I'm doing wrong is a) I shake like a dog shitting razor blades so it's never straight (!!) and b) I often get the material too hot.  I had the settings really good early on then changed it to weld a thinner piece of material and couldn't get it back to where I had it!!  It's hard to find that fine line of maintaining a good puddle and keeping up a good speed while adding filter at regular intervals, especially when you're welding around corners all the time (pipes) and need to constantly rotate the piece you're welding.  The pros make it look so easy!

Welding the wastegate merge on was the hardest bit of the lot.  I cut the end off to get in there a bit easier but still found it really difficult.  Also welding it back on where I cut it off was hard too.  I stuck the tungsten out further to reach in there a bit further but then the weld suffers from less shielding gas around the weld zone.

 

[mr_rbman]

gas lenses make a weld ? of difference.

12l/min. is typically the max i would run... up to 15 when need to protrude the tungsten that bit further...

That black discolouration you get instead of the nice straw finish will typically be the result of a poor gas coverage as you've alluded to...

 

[Shoota_77]

@mr_rbman boom boom!

Thanks for the tip. I might try a better Pyrex lens kit. They look better than what I’ve got. Wouldn’t mind trying a 10 or 12 sized cup for better coverage. 

[Shoota_77]

Not much to report, received the replacement flex joint for the dump pipe so cut the dump and removed the right amount. Tacked it all in. Finished off the last section of wastegate pipe. 

Back purged and fully welded the whole dump pipe and make a good start to welding up the wastegate pipe. 

Exhaust should be finished by the weekend thank God!

I've put the pressure on myself and booked it in for a tune on the 21st of November. My birthday....  Gutsy move but I need an end date to work towards so I don't slacken off!  The end of the is somewhere in sight!

[Shoota_77]

Finally finished off the exhaust today. There's a couple of bits I'd redo if I had the time but it can wait. I'll get it up and running and worry about bring pretty later on. 

Was definitely a learning process. Even after all that welding I still don't nail it every time! Such a hard thing to perfect. 

Got a start on the intake pipes. Throttle body side tacked up. Still need to add the blow off valve pipe and make up a bracket to bolt it to the body like the factory setup. 

Anyway, VERY happy to have ticked off the exhaust,  it was probably the hardest bit of the whole conversion so great to get it out of the way first. 

[Shoota_77]

Pretty much finished off the hot side of the turbo to intercooler piping.  It could have better to be honest but I can always redo it later on.

I'm out of Argon so need to top up today before I can do any more. Hopefully I'll get the cool side of the intake piping finished over the weekend. Its a bit trickier than the other side as it has the blow off outlet. I also need to mount the water/meth mister in that piping too. I've got a basic idea on how I'm doing it but will play around once the rest of the piping is finished. Shouldn't be too hard though. 

19 days till my tune booking so the pressure is on! 

[Shoota_77]

Down stream of intercooler piping is done. Damn that was a mission.....  I think I just made something simple really bloody complicated!

A lot of pissing around but came up ok in the end. 

Apart from water/meth nozzle all piping is done. I'm really enjoying all this welding, going to need a future welding project to keep my eye in. 

Next is plumbing the coolant, oil and oil drain to the turbo. Should be pretty easy compared to what I've already done.  Ive got an Aeroflow kit for the coolant and water so should be nice and neat. Turbo drain looks tricky with minimal clear paths from turbo to block fitting. Might have to make up some metal tubing to get past the turbo then just hose from there.

Welds are getting better with each post, nekminnit opens up a tuning shop called Shoota Fab

Yeah definitely rolling out some nice lines now.  Trust me, I still completely F up the odd one still!  I'll think I'm flying along then next minute hit a thin spot and blow a hole through!

I'm pretty good at filling holes now, plenty of practice!  My skills at welding together non perfect joins are all so a lot better that a few weeks ago.  At the start of this unless it was a perfect butt between the two parts I would be in all sorts and blow holes everywhere.  Now I can still move along pretty well even with a 1mm gap between the two parts.

As for a tuning shop, it's every car nuts dream but unfortunately I understand that it's not a reality for me now.  However, if I get sick of flogging cars for a crust then who knows!  It's crossed my mind many times over the past 5-10 years every time I question my commitment to what I do now.  Car sales management pays too well to just up and leave it so I think I'm stuck for good!  Selling cars is like the mafia, you do it for a while, decide to get out cause it's killing you, try something else for a while then realise the money and perks just aren't the same outside of the game so back in you go!  I've only pondered leaving, not actually done it like many others that have and regretted it.

 

[Dose Pipe Sutututu]

Come to Syd, you build cars, I'll tune them and run the online parts store. 

Then out back we'll put in a skid pan lol.

(Pipe dream, well maybe not you're already fabbing and building a car and I've got a new e-Comm store and I do tuning on days when some clapped out Silvia owner is too poor to pay a shop)

I digress, keep up the good work man! I wanna see skids

[Shoota_77]

Ha ha, you've got it all worked out!  What do you sell in the e-comm store?

I've love to think I'd have this thing running by next week if I can put a decent amount of time into it this week.  Melbourne Cup Day tomorrow so will hopefully get most of the day to work on it.  The kids will get fed breakfast and lunch, other than that they're on their own!  The good wife is working so I'm on dad duty.  That generally means spending as little time with them as possible!   I love them but they need to learn to be self sufficient in case of the next zombie apocalypse.....

Mainly brake pads, fluid, and Turbosmart whooshy parts. Will list up more crap when I'm back from my holiday (currently in Korea).

Dirty plug time, www.nhbautomotive.com.au 

So hard finding time to even drive the car, let alone working on it. Last time I paid someone to work on mine, it came back with a fuel leak and power cabling not terminated properly to my fuel pumps. Not to mention the lack of a fly back diode so I burnt through two SSRs.

Just put some movie on for the kids, hand them a tablet each and done lol.

7 years in the making? Man that's dedication, I've given up on mine. Need to reseal the sump properly as I did a shit job the first time and change the FMIC then it's club 600hp but ceebs now, especially buy the Tiguan ?

[Shoota_77]

Cool, I’ll try to remember to order from you next time I need some stuff. 
7 years shows how terrible my dedication is! I’ve had that many false starts it’s not funny!  This time is finally the time though. I can almost taste it!

Enjoy the rest of your holiday.

Thanks @Shoota_77 and as always I take care of SAU members, whatever prices you see on the site are just there for the sake of it

Just PM me if you need anything and I'll try my best to beat any legit price you find (no Fell off a Truck prices from Moey DW lol)
