I am single now with a TO4E and I plan to upgrade hopefully this spring but it may have to wait until this fall or winter. In any case, I am looking to upgrade my IC, fuel system and of course the turbo. I am looking to get over 500rwhp and still have PS and AC. Will the PFC be able to handle this???? Or do I have to upgrade?

Thanks,

 

The PFC is going to handle anything 90% of the RX7 owners throw at it. I know there were some drag cars making way more power than that and still running the PFC. Worst case, if you get wild enough, you'll just need the datalogit to allow you to use the exceptionally large injectors (like 1600 and higher). But you'll want the datalogit anyway if you're going as extreme as you say. You can even add in an extra set of 850's using the datalogit, and a plate that they sell, if that's the route you want to go.

 

Great info thanks a lot. It is good to know I spent well with at least one thing (ECU upgrade). 'Cause I still have to get rid of the I/C, probably the intake and ...

Now I have to raise a few more dollars and get this thing going...

 

The PFC can handle it but I don't think I've ever seen anywhere close to 500rwhp from a TO4E.
