3.8 VRAM on a 3.6 engine
I have access to a polished and ported VRAM from a 3.8 RSR. Will it plug and play into my 98 3.6 or will modifications be required?
The only thing I can think of is that increasing air intake flow might require adjustments to the fuel system. If so, would an adjustable fuel pressure regulator or higher capacity fuel injectors do the trick?

Remember the additional air 'in', must have a way 'out' .. and sadly, the ceramic coated exhaust ports kinda limits us on meaningful mods.

If it's the intake from an RS, you can get it to work w/ some rewiring of the DME connections. It's not plug and play even if you have a 55pin OBD1 DME as used on the RS's. Which you don't have on a '96 up US car(OBD2, 88pin connectors)
The exhaust is not a bottleneck on these cars, just use a good cat bybass(sepatated sides)
You wouldn't get the full benefit w/o cam, valve and chip changes to accompany the intake

Thanks for the responses guys.
In the even that I choose to pursue this:
What kind of power improvements could I expect?
If changes are made to the DME as suggested, will emissions still be a problem to contend with?
I have a Rennsport chip and DACH X bypass, so I'm partially there in terms of being able to use the larger air flow. I thought about doing RS cams but by the time it all adds up, I may as well do a 3.8 converstion and that's just too much money for the return.

All TTs are AWD. A TT was my original plan but I now belong to the small camp that prefers NA. I'm just trying to squeeze all the power I can get without having to spend $15k for 30-40HP.

Hey Greg, long time...
I hear you man, but you can't blame a 993 brother for trying to be creative. Coming upon a 3.8 polished and ported VRam doesn't happen every day and I'd really like to know if I can gainfully use it.

Get the rest of the package if you're willing to spend this much time, energy and $$. The RS 3.8 is a dream come true. Hurry though, it will be winter up there before you know it.

RS had varioram, RSR were only built as race cars and had a completely different intake system.
ROKN, Have you considered tuning the 3.6, it doesn't take much to get up to RS 3.8 levels and if you go for 9M heads you could go well above factory 3.8 output..3.8 is ok, good torque, but feels quite a lazy engine in operation (owned a couple, driven a few others).

3.8 and 9M (if it were available on this side) is too much $$$ for the power gain IMO, but then again, a test drive might change that perspective.
