Just got back from Xtreme. Simon was busy so I spoke to Shaun. Anyway,I have been quoted 6500 for race air box,battery relocate,valve springs,surge with twin fuel pumps and GTX3582. Shaun went and asked Simon how much for the Precision. He said 3000 on top but its not the 6235 its one they use not sure which one but its a lot of work to get it on. He said they do another one which is easier. I said is it the 6235.....hes not sure but he will call me tomorrow. I expected more but $6500 before now $9500. Doesnt seem right. I hope he gets back to me and says the 6235 is cheaper than that. Going by what people are saying the GTX3576 might be the better choice. So the GTX3576 is better than the standard FG F6 turbo. I like the quick spool but want a bit more up top.

Small turbo wont go near F6 turbo unless its on E85.

Do you want E85?

397kw on 20psi tapering to 18psi on 98 octane.

425kw on 25psi tapering to 20psi on 98 octane.

This was achieved using a gtx3576r on a 1.06(ford) rear housing.

The same car had previously ran the f6 turbo and made 430kw. Not much difference in the peak number. But response, low down torque was superior on the baby gtx.

Stazza, what boost was the f6 turbo running?

Very impressive numbers from the little GTX!

I imagine that car was a real weapon

Spool is over rated. That vid looks like just wheelspin city.

Very good results have been seen with the 6235. Comparatively to the gtx3582 it comes on earlier and hits higher peak power, from the testing I've seen

[MattyP]

The 6235 seems to be the go atm

But like has been said before If it's a daily or you do long trips

You will miss the response of the standard turbo

Got home from night shift, straight into the car to pick up turbo from couriers.


Came with the housing already bolted on the rear.
Tested the retaining plate for the compressor cover against the stock B series wastegate bracket.

Winner, exact same pattern.

Bolted on with stock actuator (turbosmart one hasn't arrived yet) and it all lines up.



(Core has to be rotated to correct position)


4inch joiner on

Comparison time..

Beside a stock B series turbo (gt3582r)


Rear housings, .82 on the left and stock ford 1.06 on right, camera angle makes the .82 look smaller then it is but you can definately tell its smaller then the ford housing. Rear flange is the same size.


Top down view of the .82 on left and Ford 1.06 on right. .82 is smaller looking from the rear but looking down from the top its about the same width as the Ford housing.


Comparing the common rear housing sizes.
Left- externally gated .63 housing
Middle- Internally gated .82 housing (what ill be running)
Right- Stock internally gated 1.06 housing

Comparing the wastegate sizes. The flap on the new .82 housing is 37mm with a 31-32mm port. This compares to the fords small 33mm flap with 25mm port. Looks like I get away without having to send the new housing away for a port job.
Bigger port from factory plus nizpro overboost valve should control boost spikes.

Just waiting for the turbosmart actuator to show up then ill be bolting the thing in. Just run on spring pressure (12psi) and watch my wideband gauge while taking it easy till I get a tune. I should be able to tell if the .82 housing is too small before getting a tune.
