BF to FG plenum conversion

I personally don’t see the sense in this, when you can change to a forward facing plenum for virtually the same cost

^^ and a lot less hassle.

I got a FG plenum for next to nothing and installed on my BF.  Instead of changing thermo I cut the end of plenum and rewelded to have clearance, also welded up throttle body holes and redid them for BF body.

I've not seen one for anywhere near the price of a fg one. Most I see are twice the price or more(though the PW one looks sweet).

Go ahead and do it. I did it to my 2007 Territory Turbo Ghia. Anyone telling you it's a $5k job is a tripper. You should find a 2nd hand unit for $300-$600. There's a little bit of work involved to fit the BA/BG TB on the FG manifold alternatively use the FG TB with a wiring adaptor. You'll need to use the FG fuel rail as well.

arent the re-manufactured new FG turbo intakes $650 on ebay?
Ive bought them secondhand as cheap as $150

You need to knock up some fuel rail spacers to use the full length B series injector in the 3/4 height FG rail. or use the slightly larger FG turbo injectors - need a tune however. 

the f series to b series TB adapters are anywhere from $80 to $200 depending on who you buy from, you can get them to point other directions in a J pipe type deal too.
I've purchased a b series to fg throttle body wiring loom adapter, I think that was around $100, but bear in mind you will need tune to use a fg throttle body.

New gaskets and general parts another $150 or so. 

so conservatively your around a grand to DIY install FG intake, assuming you can make the connecting cold side intercooler piping also. 

my last falcon tune was around $800, but some places charged around 1200$ here ... so if you leave the fg injectors and fg Tb in, get a tune, your around 2k?

 

I dont know whats a workshop would charge to change your intake, but surely its not 3k.

Not sure what the price of the intakes are, I paid $600 for mine off ebay.

 

Agreed, you need spacers for the injectors or run the FG injectors. Good time to change over from the BA/BF intercooler setup for the FG style setup.

 

Put it this way, I have the FG turbo setup in my 2013 SZ TS petrol Territory, the FG FMIC and piping fits like it was intended to do so from factory.

so will fg intercooler and piping and plenum fit on ba

just read the posts in this thread... thermostat, fuel rail, throttle body etc you have to stuff about with to make it fit.
