3" turbo back with psi
 

will this be fine with a stock ECU? I have 3" turbo back, no cats and upgrade intakes? will it be too lean? I am porting the wg and doing non-seq. Tell me what you think. It will take a little bit of modding for me to get the dp on since my car is jdm and the steering shaft is in the way!!!!! Man!!! let me know what you think, Thanks Brian

JDM cars don't have a precat. I think you should spend a few days or weeks reading on this site before you go near your car.

lol good call I guess...... thanks I think

Sorry to be snarky but you cannot just mod these cars and hope for the best. If you plan on removing the main cat you need an aftermarket ECU and tuning. Even if you port the wastegate and keep it at 10psi you are going to be on the edge with no cats.

Stock ecu, leave the main cat on.

The car will be plenty fast with a dp, cb, intake. Make sure the boost stays at 10 psi.

Btw, porting the wg is not a fun, easy, or quick job if the turbos are on the car.

thanks man, I thought that but not sure. I didnt know about the no cat on the jdm. I didnt trust you so I checked and.. well you know, no cat. thanks again!

non sequential on stock ECU will throw codes normally

That's why you put 330 Ohm 1/2 watt resistors in the plugs that were attached to the rats nest solenoids. No codes.

Get a power Fc, problem solved...

5-600 now or 3000+ very soon :wallbash:

who makes the PMS and where can I get it?

forget that last one I know who makes it. but its not listed on the web site why?

Fd3s4e that wasnt your only problem :rolleyes:. Soon enough you will be back on the road :icon_tup:

Brian, as others have suggested leave the stock cat in until you can get a new ECU.

Really? What kind of AFRs are people seeing?

Yeah but its a barrel of laughs with the turbos off. :tonque: I think it took me 2 hours with tungsten carbide bits on a dremel to port the wastegate during my non-seq conversion.
