TO4E
 

I have bought a TO4E to put on my 3rd gen. It has a .60 ar on the compressor and a 1.15 tang. divided on the exhaust.
What kind of lag will i have?
What is the Best MAnifold and down pipe?
Where can i get the Lines to hook up the oil?
Does anyone have pics of theres?
Thanks

you need to get a custom manifold from someone like crispeed, it will have divided manifolod all the way to the turbo entry, that way you get the least amount ot lag, and make the most of the turbo's divided exhuast housing

My T04E is the HKS kit. I am fairly sure it has a .96 A/R. Boost starts to come in (feel) around 3200 rpm. It really starts to kick around 4000 rpm. I don't have quite the right figures yet as the motor is still being broken in. Everyone has told me the boost kicks in a little higher than stock and just keeps on pulling. One important thing is there is not the power spike around 4500 rpm in the middle of a turn - bad bad bad!

T04E is great for the street - you will love it!

Hey carcrazy: what kind of fuel system upgrades do you have with the TO4E?
I have the same turbo kit(TO4E HKS) and yes, it has on the compressor housing .60 A/R. I also have the Haltech but still don't know what injectors to run.
thanks on any info

Red Baron: It depends on the boost you want to run-

I think 850 primmaries and 1200 secondaires might be enough (once again depending on boost and HP you want)

4 x 800cc injectors will suffice, as will stock primaries and 1600cc secondaries.

Thanks for the info. I am still thinking 850 x 4 vs. 550 pri and 1600 sec from RP.I want to keep the Rex as streetable and responsive as possible. Max HP is not the primary goal.
thanks again for your input

Here are the specs I am running. So far, X S Engineering did not have any compliants on the choices and did a great job tuning the PowerFC.

Aftermarket fuel pump. They showed me the stock one. It is quite small the diameter of the outlet. I am not sure the aftermarket pump.

The injectors are: Primaries - 660 cc
Secondaries - 1200 cc

I will also run the APEXi - AVC-R for boost control. Therefore the car will have two modes of boost. One at around 8 psi from the spring setting inside the blowoff valve. The other is when the AVC-R is turned on. Then it is tuneable to a safe boost.

Hope this helps!

Will you have an aftermarket ECU? I have the Haltech running 550 primary and 1600 secondary. I cannot feel the secondaries come on.

It might be different without a real aftermarket Engine Management System.

Mikel: thanks for your input. Yes I do have a Halteck E6K but what do you mean by not feeling the secondaries come on?
