I was under the impression that these needed to be modified to work in the s2000 fuel rail/ intake mani.
Who is running these and what was necessary to fit them?

This is good info, but also raises some questions about 08 s2k's.
I have read some posts about these not having a fuel return line, and that 400whp on gas, would be a limit for what the system can handle.
My intended flow will be higher than "gas 400whp" as im trying for 350whp + on e85.
On the 2005 s2k I had, a walbro 255 was enough for 325whp (e85), but the siemens injectors were the limit. Had to take down the tune from 350whp.
When you say bosch 044 inline, is this inline with a walbro or the stock pump or something else? Are there any other alternatives that lets you install a drop in replacement like the walbro with more capacity? (I am just thinking that one pump screaming is better than two)
The injectors seem to be a safe bet from all I have read so far, so these I'm not worried about anymore. Clearly an alternative for my application.
Best regards

Leave the pump alone and get a Kenne Bell Boost a Pump. Simple and clean solution.

Would this work for an ap1 sideways? Would be nice not to have to replace intank pump.

For me, the work with having to replace the intank pump is no problem, it went smooth last time and I am not scared to do it again. What I do care about tho, is a clean installation and I would like to avoid excessive noise if possible.
Where should the boostpump be placed? How about wiring etc?

The boost a pumps are pretty simple and also pretty effective. Something worth considering if you're only needing 30-50% more fuel than your current pump is capable of.
The real problem with a returnless fuel system though is that as boost increases you lose the pressure ratio across the injector and it severly limits the power potential of a given injector. For those that don't understand what happens, to put it an easy way. If you were running 50psi fuel pressure and 50psi of boost with a 1:1 rising rate regulator, you'd end up with no fuel flow through the injector. It's important to maintain a consistent pressure ratio across the injector.
The proper fix for a returnless fuel system is a 1:1 regulator and a return line.

Ill look into that then, seems like the 08 is more complicated to set up for turbo than earlier models.
