How A T04Z Could Be Fitted In The Factory Position

[Ricky N]

The T04Z can be fitted in the factor position.

An adaptor spacer plate with the correct stack height can be bought off the shelf from RotoMaster that allows the T04 bearing housing be bolted into the factory Ford or any GT30R or GT35R exhaust housing. The factory Ford exhaust housing will still need machining to match the profile of the T04Z’s P trim turbine. A machinist or turbo shop will need to do this precise machining. A new oil feed line will be required or if you already have a braided line a new fitting in the turbo will be required. New water lines and oil drain required. The T04Z has a 4” inlet and will move the front of the turbo about 20mm forward so a new air filter pipe is needed.

The 1.06 A/R GT30R / GT35R exhaust housing is NOT a restriction on a T04Z as some would have you believe. This housing is similar size to a .84 T04 housing. In fact The 1.06 A/R GT30R / GT35R exhaust housing has a nicer volute area than the T04 housing that comes standard on the T04Z.

This turbo conversion is a much better option than a T04Z compressor wheel high flow / GT3566R that many opt for.

Most people will look and think all you have done is a .70 compressor upgrade.

Any well equipped turbo shop can do this conversion. A handy machinist could do it as well.

A machinist could make the adaptor plate as well but for the price it is easier to buy it off the self ready to go.

very interesting for those who dont want to spend 1200+ for manifold and 2500 for a turbo, but chasing 400-450rwkw! More R&D plz!

well that depends how much this is I guess

if we supply you with the ford housing and you supply the turbo, what's the price on this conversion?

[Ricky N]

Sorry I am not working on turbos at the moment.

Here are some average prices to use as a guide. You will need to talk to individual turbo shops to get exact prices.

Bearing housing to exhaust housing adaptor spacer plate $110.00

Exhaust housing machining/profiling $150.00

New T04Z $2200.00

I have done something similar years ago on a 32GTR. Upgraded from a GT3582R to a Billet Z-P which is pretty much exactly the same as a T04Z except the Z-P has a cropped Turbine so flows slightly more. The T04Z/Z-P was put into the 1.06 A/R Garrett GT35R exhaust housing.

The T04Z/Z-P on a very lightly modified RB26 made a bit over 500hp at all four wheels on 20 odd psi.

The power is not huge but is respectable. More important was the power curve.

Here is a dyno from AutoSalon:

I have had the shaft on a cropped P trim turbine reground and put into a GT35R bearing housing with a T04Z compressor wheel so to be a total bolt on T04Z but the car has not been tuned yet so don't know how the turbo is going to cope when lent on. It has been daily driven for about a 10 months though and is still going strong so fingers crossed.

Putting a T04Z core into the XR6 housings is going to be a much cheaper option than what I have done above.

Is the part on there web page?? I had a look and can't find it.

unfortunatlly im not a fan of how turbo modifications work on different cars. Would only be interested in an xr6t setup.

In saying that, I am interested if some of the experience on the forum can relay some information on the topic. I am lookin for a new turbo setup later on but if I can just bolt on a to4z as above to give me that bit more, for minimal costs....cant say no.

I didn't look on their website but I know they sell them.

Would be worth speaking to Kyle at 6boost. My car is out there at the moment having this work done.

Yeah sure but that wasn’t what the example was for. It was to show the turbo can and does work well in that housing.

The 1.06 A/R GT35R housing is around the equivalent of an open .84 T04 Housing when used on a T04Z.

If you are looking for comparable examples on Falcon’s see how the guys that are running T04Z’s with .84 housings are performing. Don’t forget to take into account that they are probably running a better exhaust manifold then the factory item.

More to the point, what I am saying here is a complete T04Z turbo in the factory Ford exhaust housing is a better and less restrictive option than the T04Z compressor wheel high flow on the factory Ford turbo.

This conversion is not limited to the T04Z either. A Turbonetics GT-K 650 or PT 6765 could be fitted by doing the same process.
