twisted turbo setups

there's a good $500 in materials (piping, flanges, gaskets, oil feed line and fittings)

and a s*** load of labour (strip current turbo setup, make downpipe, make up-pipe, make intake pipe, refit all parts)

true at a shop my bad but blimey ! the gains aren't worth that..... better off with a possum link

Fit a real turbo (rather than a weeny factory VF) and then see some real gains ;D

Depends, for one if you aren't exactly mechanically minded like myself lol and have a knack for breaking crap when I try to be a mechanic. ;D And if your setup is including a much larger turbo at some point as Koom said.

true if you can pay for a dinner plate like yours then some $$$ for a twisted setup is just change i suppose

$400 landed in NZ off eBay isn't exactly Oprah money

Problem I have is that it takes me 4 hours to remove the damn thing. So it took 4 days to build the up-pipe and downpipe for it. Going to lift it higher this time round to find some space.

What your turbo was 400 landed? What kind is it?

[Koom]

Holset HX35w with 12cm hotside. Lots of them for cheap on eBay and easily rebuildable. If you feel that it's not giving enough power you then buy bits of an HX40 and build a hybrid for not much more.

Were/are you happy with yours? Did you build a hybrid? How much power can it support?

[WRXER]

It's awesome, I have turbo envy at the moment....

[rex-leggy]

it sure looks the part! now i know the turbo i can get a variation so i dont copy

joking mate

With the first setup I had it on, it had a rather high threshold. i.e. 5.5k rpm. But that was a twin scroll turbo sitting on a single scroll manifold. Once I get it set up properly this time round (spending time and money on it this time rather than just time) I'm confident that it'll give me a decent amount of power. If it can reach 300kw I'll be happy but I will need a better ECU and injectors to do that but keeping the Possumlink until I've run it in as I know it runs.

I didn't build a hybrid as I felt the compressor maps I felt were about right for a 2.0L. I think the hybrid might suit a 2.5L better?

There's a multitude of Holset's out there for cheap but can be hit and miss on what you are actually buying. They come of big diesel pickups so often have massive hotsides. There's a few different turbo's in their range I wouldn't mind playing with if I had the spare coin.

[sultan]

very interesting. yeah i've done the big twin scroll on a single manifold, it's really not a good idea lol.

i imagine even twin scroll mani with a 12cm will still be a bit average on a 2.0

look forward to seeing your results!

So am I! Has been a while since I last drove it and I've finally gotten withdrawals and motivation to get it up and running. Hopefully spending tomorrow morning in the workshop to get the crank in the block with the help of Tony at RDL then I'll be needing to spend a few weekends fabricating stuff for it. I just want to get the threshold to somewhere in the 4-5k rpm region and I'll be happy as a pig in sh**. The top end is going to be good no matter what ;D haha

[WRXER]

Damn you lol my car has been gathering dust since I've been Auckland. Can't wait to see it, no doubt after having a ride in ur finished project I'll be off to the bank for the loan haha stuff saving for my setup.

[sultan]

how much boost did you run through it on your last setup? even with the rediculously long spool time, it'll have been an indication of what power will be like when setup properly

Mines got Brembo's now too. Thought I'd just put that out there

It was running good at about 24psi. The resolution on the Possumlink was the MAJOR limiting factor. I was out playing with it at 27psi one day for fun (friday afternoons were our tuning the RS evenings) while trying to keep the injectors below 110% ;D (740cc's and they maxed out around 25psi at the top end of the revs) and it popped the headgasket. I'd had a leaking issue for a long time as it slowly drank water but I didn't rebuild it before shoving a million psi down its throat.

[sultan]

how did your map sensor cope with that? i imagine it didn't, lol.

well if it was providing enough air to max out 740s you should get your 300kw i would think

[Koom]

Was with a 3Bar GM sensor. Maxed that a couple of times in the mid-range when my boost solenoid packed a sad. Fun times ;D
