Robtune 550cc
If I were to run 550cc Top feed injectors, instead of running the adapters for the yellow top side feed injectors, would the 550 tune still work? I found some 550cc top feed injectors online awhile searching around

Re: Robtune 550cc
I don't think the injector latency (dead) times are going to be the same between the side & top feeds. If you can find that information about both types of injectors you could clarify that.
Are you planning on using a different intake manifold? If not I think fitting the top feeds on there would take a lot of work.

Re: Robtune 550cc
I read somewhere that too feeds would work on the stock fuel rails without the adapters. Maybe I read wrong. Phase 2 adapters seem to more commonly available then I thought. Probably would end up being easier to get the yellow tops and adapters.Legacy777 wrote:I don't think the injector latency (dead) times are going to be the same between the side & top feeds.

Re: Robtune 550cc
Top feeds will not work on the first gen Legacy fuel rails.
What adapters are you thinking of using?

One of the kits I found is by a company called Deatschwerks, haven’t looked around the fourms to see if any one else has used them.Legacy777 wrote:Top feeds will not work on the first gen Legacy fuel rails.

That kit is for the Newer Subaru manifolds. I don't know if they would be a direct fitment on our cars without some work.

I’ll take a look at the injectors and see if it looks like it’ll bolt upLegacy777 wrote:That kit is for the Newer Subaru manifolds. I don't know if they would be a direct fitment on our cars without some work.

The tune was developed with a specific set of hardware in mind. Deviating from that exact list of parts is a gamble I would not be interested in taking.JimBos Legacy wrote:If I were to run 550cc Top feed injectors, instead of running the adapters for the yellow top side feed injectors, would the 550 tune still work?

Re: Robtune 550cc
That’s why I’m thinking I’m going to go with Robs adapters that he sells, he mentions that deatschwerks work aswell, but are a bit more pricy.carfreak85 wrote:The tune was developed with a specific set of hardware in mind.

Re: Robtune 550cc
What intake manifold do you currently have, Jimbo?

I don’t have the exact part number, but it’s the stock manifold on a V1 Ej20Gmike-tracy wrote:What intake manifold do you currently have, Jimbo?

Re: Robtune 550cc
Ahh. all you need to do to use phase 2 sidefeeds is ej25d (all years, 96-99) rails. I know you were talking about retrofitting top feeds, but Rob's conversion kit does the same thing as using ej25d rails on an ej20g manifold.

Re: Robtune 550cc
Gotcha, so it’d probably just be easiest to run robs adapters. I can’t seem to find the ej25d rails anywhere, but maybe I can find them at a junk yard somewhere around heremike-tracy wrote:Ahh. all you need to do to use phase 2 sidefeeds is ej25d (all years, 96-99) rails.
