do it

not a lot of progress this week been busy stripping apart an Austin healy body, drilling spot welds and disassembling everything body wise.

but managed a couple of hours on the turbo manifold, now looking more like id imagined .

Good work dude - defo gonna make my own one for the fj - gotta get mounted first.

You should have this running in no time

another week of working mostly on other peoples cars, but managed a couple of hours today while waiting for underseal to dry on Lukes coupe, If anyone wants the underneath of there car undersealed, DONT RING ME, the job sucks in the worst way, took me an hour justto mask it up.
Anyway the exhaust part is now fully welded, and ground back ready for media blasting etc.
so I have started on the inlet side of things, this part of the equation is highly experaMENTAL I bought some side entry injectors although at the time I actually wanted top feed, but once I saw how the side feed ones were constructed I came up with a plan on how to make it all work.

I cut the fuel rails off the sides and bored out the pipe that was left in the body, then I extended the bottom of the injector housing with some steel tube, drilled some holes in the inlet runners, and slotted the holes to allow the injectors to lean back on an angle, once I had the injector bosses fitting in the slotted holes I fed a length of steel tube through the body of the injector bodys to keep it all aligned .

The steel tube was purchased from safe R brakes and my arse still hurts from the reaming they gave me with the price.

Once everything was in alignment I silflossed the injector bosses to the inlet runners, (silfloss is a form of brazing designed for steel,copper and Brass but flows more like a solder when at the correct temp.) Great for sweating injector bosses to inlet runners.

as you can see in the pics the tube has been removed from the bosses and will need to be cut to lengths and sweated between the bosses to complete the fuel Rail.

So now the injector bosses have been attached, the runners are on the flange, I will need to finish things up and install the injectors and then pressurise the fuel rail and test to make sure there are no leaks.

hopefully this will all work out as im not sure many (if any) people have actually gone down the road of welding their bosses to the inlet runners.

Hit hat with a flapper wheel and it will look like a million dollars !

lol already been at it with the flapper disc,

cool wal, Just had a thought what temp does silfloss melt at?
as we talked about the manifolds are going to get pretty hot, could the silfloss melt out?
I wonder if you chrome over silfloss, maybe heat coat your turbo manifold and chrome your intake to keep as much heat out of the intake?

They make a number of different compounds according to their site

At my work we use Silverflo 45 (easyflow pretty much) for power steer hoses and small hydraulic hose ends (same as what I used on Greg's car, works great to 3000psi or thereabouts) and we also sometimes use a silver-nickel compound on big stuff. If you do run into trouble with your joints melting I can nickel silver them at work - I know it takes high temps because it's been holding my cat temp sensor bung in my de-cat pipe for almost a year now, as well as being used directly on my exhaust manifold to block off the EGR system!

Looks good, keep it up!

Hi Warrick,
I can't see heat being an issue as mine were easyflowed on and then powdercoated over and I never had an issue with the powdercoating melting which I would imagine would happen long before silfloss would melt.
Looks great and you have made some serious progress there.
Go the A series!!
Cheers
Dave

there we go, the masses (who know more than me) have spoken!
