ok so im kinda of new to this and i just bought a rebuilt t25 turbo of an sr20 turbo and i also got greddy
PRofec B-Spec2 boost controller, AEM Gauge-Type Wideband UEGO Controller, and boost guage to go with it, and i need some help finding a manifold and downpipe that would go with my car and turbo, also i was wondering if i can use my stock ecu and tuned it to go with the turbo ecu. And also if any one can help me to find the rest of the things i need for the set up..
thanks.

 

A lot of people will recommend BEGi who already makes a manifold and DP that'll work with that turbo.

 

yeah i have called them and asked but they were chargin me 800 and right now i don't have that kind of money

 

you could go for the hks manifold but no one besides racing mazda (forget anything in a timely manner from them if at all) makes a dp for it.

the only real bolt on mani and dp combos are from begi or fm and if you feel like paying shipping AVO from down under (correct me if im wrong on that one).

As for the ecu thing judging from the price of the dp/mani comment, you might be going with the emanage blue or perhaps a megasquirt?

Most board members will tell you to get the emb or ms on there now and get it running NA before you bolt on the turbo, that way you can get it running with less compound issues, if something is amiss there are alot less things to look over when its N/A.

In my opinion unless you are doing the tuning yourself, there is no REAL need for the wideband, dyno operators will have one that they can tune the car with. Just my opinion.

 

ok i got most of the parts now all i need is to get a downpipe and recirculatory BOV, also 550 or 460 injectors

 

what kind of boost you trying to run? bov from bosch can be had for 30. But 305's should suffice. Check RX-7 forums for hte larger injectors and send them to be cleaned.

 

i was thinking 460 or rc 550 injectors i've tried to register but they haven't send me the email to verify i have registered

 

i was looking at 8 to 9psi prob.

 

okay for that you should be safe with 305's lots of people have them They're from a Supra.

 

does the '03 have a retrunless fuel system? if not I suggest you stick with OEM injectors, a new fuel pump and FMU.

idling 460 or 550cc injectors is not going to happen on the stock ECU, and it doesn't sound like you have the budget for an EMS.

 

yeah i think so
