I did this mod a few months ago and managed to snap a few shots of the process.
This is for those who want maximum simplicity and low costs involved in a small upgrade.
1-- Remove the front left wheel of your car.
2-- Take off the inner guard black plastic lining. All the bolts holding it in should be plastic and quite easy to just pull out.
3-- Undo all the bolts holding up the R33 SMIC, and also make sure you loosen up the clamp in the engine bay just under the air filter (shown in the 2nd picture). You may need to temporarily remove your airbox (if you have one) to get to this clamp. I had a pod filter so there was a fair bit of space for me to use.
4-- Once the R33 SMIC is removed, install the R34 SMIC into the exact same locations as for the original intercooler.
5-- Reconnect back the inner guard black plastic lining. You will notice that as the R34 SMIC is taller than the R33 SMIC the guard will stick out a bit, or may not bolt back on exactly the same as before.
For me I bolted it all back (with a bit of gusto) and let the guard hang out a bit as a make-shift scoop for the SMIC. Nothing has flown off yet so it seems to be doing the trick and feeding nicely.
DONE!
Probably the easiest mod you will ever do as a beginner - I hope this basic tutorial will be useful to people
After the mod on-boost kick was harder (this may be a mental thing though )
