I've been doing some research into injectors and have some info on the stock units.

The stock injectors are INP-470 which, according to this page, are manufactured by Nikki. They flow 172cc @ 3 bar.

From what I have read/seen so far it looks like Nikki injectors use a Denso (ND/NipponDenso) connector (round, commonly referred to as "F" type).

Apparantly 03/04 WRX injectors are what i'm after. Direct swap and 380cc. 7MGE will fit straight in too, and around 310cc. 1UZFE are also direct fit, and 250cc.

so how would this compare to say a train, which I could also afford?

any idea how far you could go with the stock injectors before you start getting problems?

A train is a light attached to a lot of metal

Apparantly, around 7psi you start running out of pulse width.

whats that equate to in HP? 7psi on a T2 and 7psi on a GT28 is a lot different HP wise

should be easy enough to get hold of though if you ask around a few suby workshops

About 130HP (at the crank) is what they'd max out at.

Any idea on interchangeable throttle body injectors damo? I thought you might have looked into it when running your 1.3L

Thought this calculator might help to Damo

I never really looked TBI injectors. I might pull mine out and have a look, see if it has a model number on it or something.

I was thinking of just pulling it out and putting the verniers on it. Looking at how they seat im wondering if any side feed injector with the same diameter in the o-ring area would fit.
