Fg Barra Motors

[Jhols1]

The Barra engines are the go, only need to do internals if going 600+hp, they are a high torque motor and a lot of fun, power glide is definitely the go.

I have seen it done but can't remember the guys name.

Only real downside is it won't sound like an RB

[iruvyouskyrine]

Not only do they not sound like an RB. They sound like absolute dick.

[r32-25t]

Obviously never heard one with a good exhaust

[iruvyouskyrine]

Perhaps. But every single one I have ever heard sounded terrible. Such a shame.

Perhaps. But every single 6cyl I have ever heard sounded terrible. Such a shame.

Fixed

lol not overly concerned over the sound. my rb sounds like balls at the mo!

But yer just throwing around ideas. if i go 25/30 ill have a power glide if not just a fg turbo engine....

[r32-25t]

If you use an fg engine you are going to need the sump, oil pick up and dip stick tube from a ba/bf

Yep definitely don't have the same aggressive scream like RB and 2J its like the tone is stuck inbetween a 6 and 8, hate there sound but awesome performance.

[Adz2332]

what increases would you expect if i used my same turbo set up and bolt ons but just added the 30 bottom end?

[jet_r31]

Big torque increase in midrange and down low..rb25s are shitboxes

anything under 3l is shit in a mid size car.

Will nose over up top due to backpressure on a gt30 turbine

For a cheap intermediate step you could change the exhaust housing to a 1.06, for a mean street setup, but eventually a bigger turbo.

[Cowboy1600]

Sound pretty f**king good to me.

[Adz2332]

1.06 is a good idea might do that at the same time.

how much do you think that would up the power and also how much laggier ?

[boostn0199]

Sound pretty f**king good to me.

Yeah thats a good example I can agree there.

[Ben C34]

Anything that makes 1000hp is going to be good

[jet_r31]

and anything way over 30psi always sounds good

cheers

Sounds like you have dicks in your ears.

Some of the comments in this thread are hilarious.

Take a look at a dyno sheet from a mildly tuned Barra 4 litre, and you'll soon realise why they would smack an rb25 like a redheaded step daughter. All while making peak power at about half the revs of the rb25, and hold it to redline.

[Ben C34]

Its hardly surprising a substantial capacity increase and a newer engine makes more power.

Interesting. I just got home from a cruise with some mates.

My mate with a tuned Barra got pissed on by an 34 tonight.

That's right, the guy in the 34 had time to stop, flop out is dick and piss on my mates car as he drove past.

Is that hilarious enough for you.

Because I find it bloody funny.
