So it’s 11:40 and I’ve been at it again since 8:30.

I had an idea from the last time I had the carb apart that the power valve was really stiff and would flip between on and off rather than being progressive.

I reseated the diaphragm after reading an overhaul instruction and also removed two preload spacers from it. I figure once boost is involved it’s gonna open no matter what.

I was right for what feels like the first time and I got my idle to stabilise dead on 1000rpm.

Still not happy with that I grabbd my vacuum gauge and plugged it in.

To my surprise I have zero measurable vacuum from what is supposed to be the vac advance port. So I tore the manifold off and resealed the adapter plate thinking it was leaking somewhere. Don’t think it changed much but I do feel there was some improvement. The original paper gasket was fully moist with fuel and coolant so I replaced it with rubber and a smear of gasket goo.

Still no vacuum on the vac advance port. So I checked the one I had blocked. Also pretty much zero but I actually got a response from opening the throttle. So I figured my lack of low throttle acceleration was due to no vac advance this whole time and now I’ve got it, it feels the best it has in a long time.

I’m glad I decided to tear into it, again.

Really hoping next time is for the turbo to get mounted.

so i got stuck into it last night, was up till 3am…

 

pulled the carb off, and completely stripped it down. bored out the throttle shaft and pressed in some brass tube and carby cleaned it and put it all back together.

 

still struggling to get it to idle under 1000rpm but its smooth now, not misfiring and carrying on. i think the throttle shaft is a bit tight as i couldnt drill it 100% perfect with a hand drill….

 

heres a short clip of it idling at 900. after putting it bac together it wont go under 1000 unless i push it shut by hand. so thinking its just a tight throttle shaft, which should loosen up over the next few days of use hopefully

Nice fab skills, you do this work yourself?

ha if only it was my own work! both the dump and the manifold came off ebay.

Had the carb fully apart last night and today. swapped the air bleed bits, and put a smaller 125 in place of the 135 in the primary. and now its much better to drive and smoother, bar being a bit rough on idle. and not being able to idle below 1100. i can drop it down to 900 and it will hold for a moment, but then out of nowhere it will just stall. so clearly its still not right, but its better than it was, so ill leave it for now until the wideband goes on.

 

further along, i unbolted the stock header and was left with this in front of me.

 

 

and here we can see the manifold in its proposed habitat

 

 

which is not going to work >

 

 

im going to need to make a complete manifold as the flange is too far forwards on the stainless unit.

 

 

 

did get all fittings sorted today, so fuel system will be attended to once it all arrives and can put it all together.

 

waiting on the sump fitting but ill pick up a sump gasket tomorrow so im ready for it

getting ready to work out what needs to be chopped or changed to make a FWD manifold fit my RWD layout.

 

pretty much just going to cut the main flange off, flip it over and go high mount and hope it physically fits.

 

3″ dump fits nicely.

My first of many silicone joiners arrived today, so fitted it up. 3″-2.25″ 90deg elbow. Off the carb hat then facing down into the first part of piping to cross over the gearbox towards the turbo.

 

Exhaust has a new tone to it since fitting the new carb and tuning it right, I quite like it. Has a strange subdued rasp to it but without being raspy at all.

Next week will be finally getting the fittings and hose to get the fuel system sorted and I’ll also see about getting the exhaust parts ready to weld up the following week.

Got my h4 LEDs today. Fitted tonight. Massive improvement in light output.  Very clean clear light too. Went from Phillips crystal vision bulbs which despite being “blue” were still quite yellow and now I have crisp white beams.  Very nice

 

 

 

Low beam, camera doesn’t do it justice of course

 

 

High beam

 

 

And while I had the bullbar off I figured I’d wire up the front repeaters too.

 

[klampykixxParticipant Coffs HarbourFord Econovan View build HERE Member since: May 16, 2015 Posts: 167]

The turbo is a Gt2871 which is apparently the upgrade size to a Silvia Sr20 type motor. Hoping I haven’t oversized ha,  considering the turbo I was planning to use was only a t25 off a diesel. Much tiny…

 

Updates will happen.  I want this done asap! Next work will be done in a couple weeks or so.  Thinking fuel system next.

Threw on some different rims n tires today,  the muddies will return when we finally work out what to do regarding a potential 4wd conversion.

[klampykixxParticipant Coffs HarbourFord Econovan View build HERE Member since: May 16, 2015 Posts: 167]

I’d love to say yes put it there!  But no it’s a bit big

 

 

Rear mount advantages are as you say regarding no intercooler,  but sizing is super important to make use of the flow rather than heat energy the manifold produces.

Thru the cab would be “cool” (pun intended)  especially if you ran aircon inside!  Maybe some finned piping to help chill intake even moreso.

 

I’ve been fixing an oil leak that sprung up and looking at potential charge piping routes and I’m thinking about running the cold pipes across top of gearbox and back up from under the carby to keep away from running over the motor. Plus it will shorten the piping too.  And keep it all hidden.  another plus to high mounting will be the potential to run the drain straight into the rocker cover which will be a huge bonus if it fits there

[klampykixxParticipant Coffs HarbourFord Econovan View build HERE Member since: May 16, 2015 Posts: 167]

Yeh pretty much.

 

In theory you could run a stand alone oiling setup for the turbo. Have a mini sump and oil pump cycling oil through the bearings but would need cooling and to be changed frequently I’d imagine.

 

Good topic of conversation there

[klampykixxParticipant Coffs HarbourFord Econovan View build HERE Member since: May 16, 2015 Posts: 167]

Turbo oil relies on gravity to drain away,  so to have it level with or below the oil level in sump requires a collection point and then an oil pump to return it to the motor. Otherwise it backs up in the bearing and can blow seals. Usually shows up as smokey exhaust as it burns the oil

[klampykixxParticipant Coffs HarbourFord Econovan View build HERE Member since: May 16, 2015 Posts: 167]

Would be massively easier to mount it low and rearwards but then I’d need oil scavenging bits.  So as long as it phyically fits as high mount I should be ok.

 

Going to run water to air intercooler so a small barrel will get mounted low and rearwards.  Haven’t decided exactly how or where it will go but I’ve got some ideas.

Heat exchanger will go up front in bullbar.

[klampykixxParticipant Coffs HarbourFord Econovan View build HERE Member since: May 16, 2015 Posts: 167]

Had a quick look at turbo position while I was in the bay.

Going to have space issues low mounting it so plan is to either mod or recreate the exhaust manifold and make it high mount instead.

[klampykixxParticipant Coffs HarbourFord Econovan View build HERE Member since: May 16, 2015 Posts: 167]

 

Took it for a drive today. Much better power delivery in the low to midrange revs, drops off at 5krpm where before it would pull right to 6k but I’m ok with that for now. Lower rev power has improved alot.  And idles so much smoother than it did.

Simplified alot of the vacuum system.

[klampykixxParticipant Coffs HarbourFord Econovan View build HERE Member since: May 16, 2015 Posts: 167]

things happened.

 

 

 

 

 

 

it just fits.

 

 

 

 

modified linkage using stock rocker welded to the holley’s one.

 

 

 

and the best bit.

 

it runs!

 

todays job entails pulling the rocker off and painting it up all pretty in black wrinkle paint.

 

[klampykixxParticipant Coffs HarbourFord Econovan View build HERE Member since: May 16, 2015 Posts: 167]

ordered my dump pipe, turbo oil fittings, and some exhaust bits.

going to be fitting up the new carb this week so ill be putting up pictures of progress.

[klampykixxParticipant Coffs HarbourFord Econovan View build HERE Member since: May 16, 2015 Posts: 167]

Haha thanks I think, pending on how this responds to boost I may decide to upsize turbo again but for now I’ll stick with the 8psi actuator and see how she does

[klampykixxParticipant Coffs HarbourFord Econovan View build HERE Member since: May 16, 2015 Posts: 167]

small update

got my wideband kit, turbo, and surge tank yesterday. its coming together pretty quick. my main holdup from here will be the time it takes for my ebay dump pipe to get here from china. this is it here for those who wanna see it,  http://www.ebay.com.au/itm/301454591099?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT

 

otherwise, heres some pics

 

 

 

2L surge tank

 

 

GT2871 turbo. after getting the TB25 apart, its full of carbon/diesel buildup. and stupid me, dropped it and bent fins on the exhaust turbine, so figured id just go new and upsize a little.

 

 

[klampykixxParticipant Coffs HarbourFord Econovan View build HERE Member since: May 16, 2015 Posts: 167]

my mate dropped back my intake and holley carby today, after making me an adapter plate and carb hat.

ill be painting as much of it black as i can in attempt to keep a stealth appearance in the bay, no big shiny pipes or anything obvious.
