STI Inlet on a WRX
I'm thinking about putting the STI inlet manifold on my WRX. It's a 2001 model so the main difference I can see is the tumbler valve.
Is this a straight fit or do I need to do something else because the tumbler valves will be gone. The car is going for a remap soon after I make some other changes so ideally it will be done when I fit the FMIC.
Thanks for your help/advice.

Jon,
The 2001 STI inlet manifold and the WRX manifold are the same apart from the colour.
Both of them have TGV's. The only STI manifold that is different is the Spec C manifold.

If you remove the TGV's you'll get a check engine light which can trip limp home mode until mapped out. As above the UK STI inlets will have TGVs I think the JDM ones have tumbler deletes and the Spec C is one piece without tumblers.

I thought the STIs were TGV-less.
This one claims to be:

Does the TGV delete make a big difference? I assume you can tweak the map to handle this if I do it. I'm just thinking of all the little bits that I'll can be doing at the same time
How much would you be after for them

Yes, i can disable the codes and tweak the map for these

The TGV body has a divider wall to split into a larger and smaller area, plus throttle plate on a spindle.
When warming up, the throttle plate closes over the larger area, so air flow velocity speeds up and atomises injected fuel more effectively to help with emissions and less jerkiness.
As the car warms up, the throttle plate opens to allow full air flow.
