Convert Internal Gated Turbo To External

[dano4127]

Just want so information on the best way to remove the internal gate setup I have a brand new XR6 3540

I have gone highmount with external gate, is there a way to do it without welding the internal gate flap? If possible I dont really want to butcher it in case I come to sell it in the future.

Cheers,

Dan

Purchase a WG'less rear turbine housing... something smaller while your at it, so it spools

Most other things i can think of, that would actually seal... would be pretty gheto.

Its going in a RIPS RB30DET so it should spool ok (i hope)

Is it as simple as buying a 1.06 hosing from GCG for a normal Garrett 3540 my worry is that the XR6 version is slightly different

[GeeTR]

3L - ahh cool.

Theres only one way to find out Call a Garret pusher, or GCG or somone that would know. I cant imagine an Australian car using something too special derived that far from a OEM off the shelf product.

im selling a brand new .82 rear housing for a GT3540, $350 +post.

external gated

let me know if interested

cheers

.82 might come on a little violent im after 1.06 and getting my dump/screamer made up tomorrow

The XR6 turbo runs a .5 A/R compressor where as the Garrett unit runs a .7 A/R. as far as i am aware that is the only difference between the two units.

The rears are the same, and I reccomend grabing the 0.82 rear because even on your 3.0l a 1.06 housing will be laggy (close to 5,000rpm)

[dano4127]

Fair enough, I had done a fair bit of research and decided on the 1.06 from what i could tell

Im going to aim for between 350-380kw

[dano4127]

ok just got off the phone from MTQ re housings

You can fit up any of the normal Gated/non-gates housings to the XR6 3540

He recommended for up to 450hp keep the internal over that go external also thinks the 1.06 will go really well on a 3L bottom end

Apparently the housings are $980 from ford so i should sell mine on the ford XR6 forums as it is brand new, he quoted $570 for a new 1.06 external housing

[GeeTR]

450hp (I assume at engine)

You want 350rwkw which is 470rwhp, so you were correct about wanting to use a ext gate to do the metering.

In the end, looks like you'll be making some cash out of this

Youll find the 30det spools nice with the 1.06, i used to get full boost just after 3800 on an rb30et (single cam) with hardcore head porting.

Wouldn't it be easier to just take it back to whoever sold it to you and say exchange this for a normal GT3582R in whatever sized turbine housing you like ?

Personally I think you are better off buying something that's closest to the final form you want to run it in , no stuffing around with housings then .

If this is a road car I would still consider the 0.82 A/R turbine housing size . If it was an all out race only car with a close ratio box slicks etc then yes a 1.06 for sure .

I think an RB25 headed RB30 will have porting and valve train limitations so its worth considering how far up the rev range the turbo comes on line , in other words if it has a lower redline than a 2630 then the higher up it starts the narrower the power range becomes .

Your calls , cheers A .

You wouldn't get a Int WG from a supplier if you wanted a Ext WG.

It most likely came from somewhere at a v.good price.

[dano4127]

It came with the motor I bought and I believe the seller of the motor had a friend who worked at ford

unfortunately I dont have time or money to buy another turbo and sell this one off

i get 15psi by 4000rpm with my manual powered rb30 twin cammed r32 using an xr6 turbo!
