Just after some recomendations as to what induction system I should get to suit the following mods 98 V4 Sti type r with 2.1 fully forged, 740cc inj, td0520g, hdi fmic, rcm headers, sports cat exhaust system, simtek ecu.

Any suggestions please.

Big cone filter is the best option, the largest one you can get in there.
RCM supply a nice one.

It is not so much the size of the filter its more about getting cold air in,feed your engine with air that has not come thro the rad will always be good

Where do you locate the trumpet?

The large cones have a 160mm I.D. open flange. The trumpet has a 160mm O.D. mounting collar - you mount the cone's flange around the trumpet's collar with a large jubilee clip. Then the other 76mm or 100mm O.D. end of the trumpet attaches to the MAF (using a suitable sized alloy MAF adaptor bolted to the MAF), by way of a suitable sized I.D. short piece of silicone hose and 2 jubilee clips.

If you're MAFless, then the trumpet simply attaches direct to the turbo's inlet collar instead.
