anyone done it?
i assume the RS2 inlet for earlier models would fit a 197 with slight modification?

You'd probably lose power putting an RS2 on a 197!
im not surprised by this comment, i have been looking into tuning the 197 and it seems nobody really has a clue what works and what doesn't, is that statement actually based on fact or are you just guessing??
Well a 1*2 with 197 cams and a RS2 inlet makes close to 200bhp. And a standard 197 in reality is more like 185bhp. So you should see around 200bhp IMO, maybe a bit more with the better VVT control on the 197.
The only problem is the clearance and the lower part of the inlet has a different bolt pattern and port shape.
Thanks, thats helpful, so what do they go for used?
A standard 197 inlet will see 230hp anyway if you spec the engine correctly. I know this. Also, converting a 172 manifold to fit on a 197 or vice versa is a hideous job. I've done the 197 inlet on to a 172 head and I know how far out the ports are. The only real way to do it properly is to weld up the ports on the cylinder head and re-port it. I'm not sure there's enough meat on a 172 manifold to do the swap the other way, and tbh you'd need to do a lot of reworking the ports to get the shape and transition half way near.
Is your cup pumping out 230 ponies now is it. I think you were sandbagging when you posted your recent pics. "nothing special" iirc was your words when asked spec lol.
