Changing From Side Feed To Top Feed

[SkudR33]

There are plenty of fuel rail kits out there, Plasmaman being on of the more expensive ones. I guess you are guaranteed it will fit under the plenum, although I usually recommend the Proflow ones since they modified them slightly to fit the RB25 better.

What the hell is a 1150cc Bosch injector? Seems every supplier is bumping the flow numbers just to make their stock sound better. At what pressure does it flow 1150cc? I assume we are talking about 1000cc EV14's here? If you are running e85 have you looked at the injectors designed for that? (Xspurt 1400's and ID1300's)

Will I be able to fit full length top feed injectors with a standard plenum on my rb25det using the proflow rail?

I know the aerospeed fuel rail also fits 3/4length injectors with the standard plenum.

i just havent heard of Xspurt before?

he fuel pump as well will flow even more then 460LPH at a higher pressure.

I think he needs to learn a little more about his products, this is just plain wrong. The pump will flow much less as the pressure rises, as he would plainly see on the flow chart.

No, you would need the short injectors which come in many sizes, to fit easily under the stock plenum. I think you can squeeze 3/4 length in there, but why bother unless you already have them.

34 Neo runs 3/4 (55mm) top feed injectors stock.

ID are a US reseller of Bosch ev14's. Somehow they got the name as the only place that can supply decent injectors in the world. Other companies also supply exactly the same injectors and modify them in the same way, Xspurt is made by a local Australian supplier, with local warranty.

Both 1150cc and 1000cc injectors are E85 compatible most others are not.

I would not be trying to screw over a long term customer lol

As scotty mentioned that is flat out wrong.

I don't think he is deliberately trying to deceive you, he just has absolutely no idea about what he is selling.

The info on flow of pumps or injectors is very easy to find on the net.

Remember, being a trader on here doesn't mean much.....

I REALLY want to see this new exact same flow injector next to the old 1000cc one.

I can't bring myself to call it an 1150cc injector because it isn't!

Also with changing to a top feed fuel rail and top feed injectors do i need to buy an after market fuel pressure regulator?

anyone??

It's more than likely. If you can't rip the original one off your factory fuel rail and fit it to the new rail, then definitely.

[Adz2332]

ok cheers im not sure how id go about retro fitting it?

[scotty nm35]

As far as I know, no-one makes a female adapter to fit the reg to an AN fitting rail. It's just easier to fit an aftermarket reg.

Otherwise retrofitting an RB25Neo rail is your only option.

There is one company that makes it and it costs $69... Link below
