The blocks are PLENTY strong. I have seen where and how they are made, the quality of the steel used in the casting process and the machine shop they are made in. I am in there regularly.

the blocks are cast from offcuts from the manufacture of body panels and are therefore very high grade steel. not cast rubbish.

I know a whole lot more about the the engineering process but cant tell you anymore than that :P

Are you sure ? I don't think I've ever seen a production engine block made of any grade of steel , they have always been aluminium with liners or iron . A steel block would be very expensive as well as very heavy and Ford aren't really into expensive and heavy .

Cheers A .

BTW the only GT2860R family turbos I'd bother using on a four litre six are the GT2860RS's , they have the largest 0.86 A/R GT28 turbine housings (which are not huge either) and std they have T04B compressor housings .

Personally I wouldn't bother with twins unless you can't get a decent TS exhaust manifold . On an engine that size even ball bearings aren't so critical because there is more than enough exhaust gas flow to drive adequate turbos into boost .

Later bush/plate bearing center section turbos are a lot better than the old (ancient) T3/T04 centres meaning more reliable .

Your call , cheers A .

the ford block isn't so much of an issue. the heads are though. i think the 4.0L engines may be a bit better than the 3.9L. i had a series 2 ea falcon as my first car and i went through a few head gaskets. went pretty well after the second one since the head had been shaved twice, LOL

also i have seen a few turbo'd 4.0L falcons and they seem to handle it alright.

That's complete crap "too big" also a built falcon engine can rev to 6000-6500rpm no worries. Standard form around 5500rpm in the old SOHC, 6000rpm in the newer Barra DOHC setup. Air flow wise a falcon @ 5000rpm for example pushes more air then a 1JZ @ 7000rpm maybe even a 2JZ.

They can rev that hard, but to make the SOHC engine efficient at that high rpm you need to have a fairly wild cam and a decent port job. And they are extremely harsh at those revs too, it's not really worth it. Remember they have a long stroke (99mm vs the rb26's 73mm), so piston speeds are getting up there as well (it's not just the head running out of flow that can stop them).

I go by how much power the N/A version of an engine makes when considering what turbochargers to use (as power roughly translates to airflow in most engines). Ie an EF Falcon makes 157kw, an R33 GTS Makes 147kw, and the only twin cam RB30 (Tommy Kaira M30) makes 177kw. So the Falcon 6 is somewhere in the same league as RB's when you are talking about turbocharging a nearly standard engine.

*edit: Oh, and I can't say enough about the EF onwards dual stage manifold. Get one if you are still running the EA-D manifold. You will need an rpm switch, a vacuum solenoid, and a computer that you can adjust the ignition timing on to suit the new runner lengths.

Exactly what parts are you using? I'm a falcon nut and am thinking about doing something like this as well...*

Sorry to de-rail again.

Pretty sure there a cast iron block dude. I have an EF as my daily and it's cast, I also have a BA block in the shed and it's also cast iron.

Look under Block Metal in the table. They have been doing cast iron blocks right from the get go.

another dirty thirty with -10s

what power is it making & at what boost level?

260rwkw on 14psi. Running hell rich but needs a re-tune badly.

sorry I should have clarified...

the stamping plant at Gelong produces 49% off cuts from the process of making panels. these offcuts are pressed into 1 foot square cubes and then melted down in the smelter of the casting plant and mixed with Iron. so it is a cast iron block with a high iron content.

this process has been happening since BA. I can not confirm what happend before that.,

I will get into trouble if i tell you any more than that :cool:

The EA-ED inlet manifold is far better for turbocharging then the newer EF onwards one. There are several cars I know of running into the 9's on the standard EA-ED manifold.

Also with all the advice you are giving me regarding turbocharging falcon's, inlet manifold, revving, head work....don't. I'm not meaning to be rude but, I have been turbocharging falcon engines since 1998. My current TT falcon i have owned for 5 years. I'm just completing a turbo upgrade and I just wanted some opinions on the -10's.

In regards to the parts I am using I'm not releasing any spec's on anything, so I'm sure that you can appreciate that.

    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
    • You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
