Fg Turbo Install On Ba Xr6. - Guide.

[Luuke]

Ok so there has been talk about putting a xr6 FG turbo on a Ba.

Well I'm doing it, WHY you ask? Cause I got it cheap and never had intention of running over 300kw anyway.

And with the better response it will provide, How could you hate that?

Turbos:

Both have 1.06 rear and .50 a/r housings. Only difference being the smaller compressor wheel on the FG.

The orientation of the housings is also different (needs to be rotated) both exhaust side and compressor side.

Also FG turbo runs higher boost from factory, so I swapped Actuators just to be safe, However when I think about it, I think this was

unnecessary as boost is probably regulated by the boost solenoid anyway.

Will supply photos and updates soon.

Using B series or f series exhaust housing?

[Luuke]

F series I assume. All I had to do what rotate the exhaust housing to match the oil/water lines.

Everything went according to plan and is nearly done, New oil and off to the dyno.

I think it's a good idea man! Might need a bit more boost to make the 300 but the response will be awesome. Especially in a 4 speed with the tall gears.

The low down boost might be a bit tough on the 4 speed.

[Luuke]

Yea that is my main concern, the low down torque. Will be interested to see how it performs on the dyno.

Any guess's what boost will be needed to crack 270kw (the aim)

Photo for comparison

[Ralph Wiggum]

270rwkw should only need 10psi or so, depending on how free flowing you intake and exhaust system are of course

[Luuke]

Will be very happy with that, I hear the FG runs 10psi to achieve its 245fkw, so if I can make 270rwkw with 10psi ill be over the moon =) I assume the FG runs lower compression ratio though to compensate for the uped boost. I have SS intake and catback exhaust.

[Ralph Wiggum]

you´ll need more than 10psi with only those mods

[Luuke]

Ok so an update.

Can confirm the response is amazing!

1st gear no longer feels so long, traction being an issue now =P

Also, for some reason. Maybe the old turbo was F**D but fuel economy seems better?

However! defiantly can tell its a smaller turbo. High RPM it seems a little dull. could use some more boooooost

But for the kind of driving I do, mostly highway ks. with the occasional thrashing. It seems good =)

Will be tuning it soon with cold air intake, catback, hi-flow cat, 42lb injectors.

Will let you know how it goes.

I'm assuming you're running the B series plenum/inlet maifold too mate which would be losing some bottom end compared to the FG 'log' style. That might be your next mod? Good on ya for trying something different mate. I'm sure it does feel perkier down low
