Rosssub's Single Turbo Conversion.

[Rosssub]

I think I got a link to an online manual for it with mine, but I remember it being poorly written and lacking info.

I've got it set up like this:

[Guest]

I was running 15psi at half. I thought the two lines were the other way round but havent run internal in 2 years or so.

[Rosssub]

I'm thinking a slightly smaller pill, or move it closer to the turbo outlet (currently in BBOD end of hose). Just to try and bring the gain up slightly, but not too worried really as the Link will sort all of that.

First trial drive with the new EBC, turned up full it would only just get to 10psi. So I came back home a fitted a 0.8mm restrictor pill in, between the turbo and boost solenoid.

A lot better, completely stable, finely adjustable boost. Currently running 1.1bar/16psi, with the HDI dial set just over half way.

I think the HDI controller has a pre-set gain level, or I need to try some different pill/hose arrangements out. Initial spool seems slower now, when I was expecting the opposite.

But either way, I'm grinning from ear to ear.

Ahhh to be rid of that VOD though..

No more 4000rpm avoided gear changes.

 

Impeccably timed, the PTP blanket from ebay arrived this morning. TMIC and strut brace off:

 

I've cut the length of wire supplied in half then made 2 straight loops and feed them under the turbo, from the drivers side and hooked them over the blanket lugs:

 

Then feed the blanket between the turbo and gearbox, as I gently pulled on the wires from the drivers side:

 

All tied off:

 

TMIC and strut brace back in:

Nice; looking sleek!

Hey I've run in to some trouble with clearances: the AVCS solenoid hits the injectors; you wouldn't happen to have spare spacers you'd sell for cheap? my head is being done in more and more, or do you reckon it'd be cheaper to get spacers made out of the spare BH manifold I have?

[Rosssub]

Nah sorry man, only the set fitted. How much spacing do you need to clear the solenoid? Mine are 4mm, pretty sure you can get 6mm and 8mm. Could also run double OEM gaskets top and bottom.

Looking at pics of the AVCS solenoid, would the motor section come off? Giving a bit more room.

[94 Leone]

Nah they're a single unit. Looking round on the overseas forums, seems 19mm is the magic number for clearing the aavcs solenoids. though i was thinking of turning the injector around by 180° and getting a bit of tube to move the fpr around the corner as it slightly hits that (with split fuel rail) only played on passenger side atm, working weekends leaves little playtime.

[Rosssub]

19mm could be near bonnet clearance limits, or it would cause issues with TMIC fitment etc. Probably better off moving fuel lines around like you are, if it works...

[94 Leone]

Yeah, all the stuff I've read though is us or uk stuff; and using v7+ 2.5 stuff so not sure how similar if at all it is. Where they are hitting is different I think. Trial & error

[iphillipnz]

How were you looking at doing the parallel fuel rail mod?

I researched a few different ways of doing it and found this one;

http://www.ludicrous-speed.com/wiki/index.php?title=Shanes_parallel_fuel_rail_mod

Thought it was pretty elegant compared to some of the other methods. Hopefully its just as easy with TT setup.

[Rosssub]

yeah you can do the same on the TT, identical fuel line setups. I've got 2 drivers side OEM fuel rails here, with the factory regulator on each.

So just a brass T on the incoming fuel line (split to feed both rails). Then another brass T on the return fuel line, (both regulators back to return). Saves buying an aftermarket regulator and bare drivers side fuel rails can be found resonably cheap.

I'm still running my OEM BHB fuel pump, planning to upgrade to a 255lph Deatschwerks pump sometime. (quieter than the Walbro).

[iphillipnz]

Yeah thats one of things of my list. Now I don't have to find a suitable pump, thanks haha. I did the fuel filter not so long ago. Getting into the tank isn't so bad but replacing the casing for the filter is a *****.

[Rosssub]

I fitted the original BH lower engine cover yesterday, then found a fire hazard today. This is the right bank spec c header touching the under cover (just melted), also the up-pipe heat shield and front-pipe shield was touching:

 

BH under cover, before and after. (4" grinder/cutoff wheel):

 

 

Now 10mm minimum clearance all round:

 

Also today my original Alt/PS belt decided it wanted to only be a 4 rib belt, so I've replaced them both. The OEM ALT/PS belt 5PK875 was too tight and always hard to get on/off. The OEM AC belt 4PK900 was too loose and at full adjustment to tighten it. So I've changed both sizes for better fitment.

 

Before- 5PK875 and 4PK900:

Some more TT spare parts came out this afternoon, this pic is looking sideways into the F/L guard. Showing the primary boost solenoid and BBOD vac storage tank, both redundant now:

 

This is the vac tank pipe running across the rear of the BH front bumper, from vac tank to BBOD:

 

All removed:

[94 Leone]

I was thinking of hooking up the vacuum storage tank to the brake booster; so that you've still got vacuum for brakes even when the car is off.

on another note; damn that is clean. mine is all caked in mud...

I wonder how long the stored vac would last running the brakes, with engine off. Wouldn't get used that much though, maybe towing? Yeah the under guards are in pretty good nick, keeps everything tidy.

Thanks Partsouq, delivered within 10 days again. V5/6 WRX/STI O2 sensor and new Y-pipe gaskets:

[iphillipnz]

What kind of price are you looking at for the o2 sensor?

[iphillipnz]

Hey ross just wondering if you had the part number of an o2 sensor for be5c handy. I seem to have misplaced the number I had written down.

[Rosssub]

Nah sorry I haven't.

[iphillipnz]

Too tired to think properly last night (too many graveyard shifts). Thought you might have the number handy, haha. Thanks anyways.

That looks like the 4 wire sensor, for rev d/e? Your rev C should be the 3 wire. Giving that your doing the V5/6 STI conversion soon, just buy the V5/6 3 wire now and use that. May have to extend the wiring about 150mm.

[iphillipnz]

You are right about the 4 wire.

Ended up paying $150 including shipping for; www.worldcarparts.co.uk/Store/tabid/667/ProductID/7139/Default.aspx?txtPartSearch=22690AA321.
