Ej20t regulator..watch it!
Hey All,
As the conversion gods still see me as a good person to throw gremlins at, I have yet crossed another bridge with what can go wrong. Maybe its because
I am constantly trying new stuff on the engine, I maybe my own worst enemy.
Anyway, when I got that 98 manifold, it was complete with rails and regulator, so I cleaned injectors and bolted it on. It never ran quite as good as
it should of, and I put it down to injectors may have been slightly different size and longer intakes meant dyno for tuning. It then for no reason
went nuts in the performance dept for about 2 weeks, then just before the box blew, it went rough again. When I went to throw the motor back in, I
checked the plugs and #3 was burnt down...lean..bad..very bad. Thats why the manifold was probably being sold..the motor had destroyed itself due to
faulty regulator. The signs were rough idle, not crisp response and looked like it was running rich at the pipe, due to the petrol not atomisinig
properly. Poor fuel economy also.
Got the old reg of the other motor..the beast is back as smooth as it was straight after the dyno..needs a bit of fuel added, although pretty sweet. I
also put the reg on upside down, so it goes straight out the side to the return line. I also made a new piece that joins #2 and #1 rails, so no fuel
lines run under the maniold. I am going to make some billet alloy rails in the next week for top feed injectors, if anyone wants a set.
Matt

They are bigger rails, although the top feed are easier to work with and you will find all the big cc ones are top feed. The design of the suby
rail(hot) and pressure reg, is an insisted upgrade if you want to pump up the boost and not go bang..Fuel pump also.

You can use whatever you want, although you really want a rising rate reg such as a malpassi, that is also 1.7:1 ratio..because boost comes on so
quickly, the regulator has to be quick enough to react to the engines needs...otherwise you get hessitation, lean out, poor response.

It was just an idea to save on cost of the Subaru one which is $150+, I think. But moving away from OE specs often means heaps of dramas
