Does anyone know what they are made of ? need to weld a flange on one and would like it right so would need to know which weld

thanks Jay

Are they not cast iron jay?

Jay,

I dont think they are mate

I thought this too. The likes of MK etc can weld them but it's a specialist job for putting on external waste Gates.

Jay,

Been told by Tony @turbosystems and Trev-rev to get the part mega hot then mig it as if you dont do the heat thing it will crack as you weld it

I'm sure you will need some different wire aswell mate for cast, or a cast rod

ajamesc

We have one of the best welder/fabricators around just off the reading road take it there mate

Jay,

iTrader: (4)

True I was thinking of giving him a bell lol

ajamesc

We use him quite a bit at work for alloy welding and machining gearbox shims that take for ever to get from zf lol. Really nice guy Andy is plus if he knows your into what he dose he gives you the guided tour lol

Jay,

iTrader: (4)

Been up there a few times lol as he buys from and we him its he is always do busy I thought if there is a way of doing it myself then I would

Regards Jay

Could be worth a try I guess. I've welded a crack on a 6 pot cr cummins engine cast manifold before as it was a 3 day wait to get one and they didn't won't it off the road. It worked but are mig is powerful and you can get some serious heat into things when you wind it up

costina

Yes you do have to get it hot before welding and keep it hot for a while.
Then let it cool down at the same rate to avoid cracking around the weld.

Similar process to tig weld cast alloy stuff too.

Jay,

Ah ok cheers Paul

could you clamp a bearing heater or similar on the manifold local to where you want to weld then try it? dont know how hot the bearing heaters get the cast but worth a try...

Caddyshack

Is this for your Borg Jay?

Jay,

iTrader: (4)

Yes Mate

Caddyshack

Wouldn't you be better off with the bespoke manifold, surely the cost would not be far off by the time you have paid the welder?

costina

iTrader: (1)

Really? if anyone is paying near the price of a manifold for welding a external gate pipe or flange then shit I am in the wrong job.

Paul

Caddyshack

After you have bought a flange, got the donor manifold, paid the welder? For a (probably) inferior product how much difference can it be....and I bet I know where the possible failure item could be on the welded jobbie. Especially if your exhaust down pipe doesn't end up in the right place.

You pays your money and takes your choice....only another option.

Jays car has had some proper cash chucked at it, why skimp on the last bits?

Adam-M

Tbh Toby it shouldn't cost a fraction of the cost, I'd expect the welding to cost Ł50-Ł100 plus material costs maybe Ł200 all in. Assuming Jay already has a 2wd manifold.

Jay,

iTrader: (4)

Already have the manifold the flange cost 15 quid and just had a quote of 50 quid

Winner winner chicken dinner 👍

Adam-M

Nice one

Caddyshack

Are the twin scroll manifolds all that much money then? I paid for mine in a bundle with the turbo and ecu etc so don't know the actual cost.

Jay,

iTrader: (4)

Yes Toby they are my is about a tenth of the price lol


Regards jay

costina

iTrader: (1)

Might be worth someone looking into having the trouser section cast with the correct flange for the bw.

Those 2wd exhaust manifolds are very good.

Caddyshack

There is a casting company near Kent that could do it but I think you would need to do a run of them to make it cost effective against buying the nor tech twin scroll to suit the bw...if you sold the others it would possibly put you in profit but I bet they would be fairly slow sellers.

ajamesc

I've read at least half the benefit of this type of turbo conversion is in the manifold and how well it flows. Be interesting to see how it dose on the ford manifold. Yes they are expensive but they do what there meant to

costina

iTrader: (1)

Toby, Was thinking someone like MK could do them and he can machine them too. At work we had alloy stuff done which was'nt that expensive.

That manifold prob retails around 1k. Just thought it could be a cheaper option.

Paul

Jay,

iTrader: (4)

Tbh I can't see a massive difference in the 2 but we will see

Regards jay

iTrader: (1)

I didn't think the BW turbos fit as the 2wd manifold puts it to close to the head ?

Be interesting to see what it dose on that manifold

Mark Shead

Yes but they are very average against the modern des twin scroll manifolds.

Mark

Jay,

iTrader: (4)

Couple of people have done it already from what I hear and I hope it works or its going to put my build off for 3 months and I am already getting the itch to sell up and buy a mk2 frs lol but my misses is saying no to that idea as she thinks i will be shooting myself in the foot and she hates the cossie so I think there is something in that some where

scoooby slayer

iTrader: (4)

I think it will be fine mate, my gtr is on stock single scroll manifolds 2 gt30s on 1900Cc each and mega responsive

Jay,

iTrader: (4)

Karl I have no doubt there will be some but for me personally I dont think itll matter lol and I need to draw a line somewhere as either way this build isnt cheap for me but at the same time it needs to be fun and the spec I have at the moment was fun for 10 minutes so it had to 500bhp lol

scoooby slayer

iTrader: (4)

It will be fine mate doesn't have to be twin scroll to be responsive

Jay,

iTrader: (4)

Oh its all twin scroll bud the 2wd manifold is twin scroll as standard

scoooby slayer

iTrader: (4)

I don't think it is mate standard has a single scroll t3 on it

Jay,

iTrader: (4)

The bw 7064 is a t4 flange twin scroll bud

scoooby slayer

iTrader: (4)

Yes mate i know but your manifold is a single scroll which will have a bigger T4 flange welded on, I'd of thought you'd be better off with a proper single scroll housing on the Borg
