FMIC.

PM Harvey on here, ask his advice about headers and up-pipe and also whether the MAF will survive, and if you need to go FMIC.

Harvey's trick up-pipes are legendary.

Whatever advice he gives, you can be sure it's NOT opinion, it's based on research he has ACTUALLY done.

I'd say 740 injectors, but ask about those too.

harvey is on holiday but he quoted me 550 heat wrapped which is a bargain and his uppipe is 149 worth every penny

my spec is similair to yours main advise would be to make sure you have sorted the cooling side as heat is playing havoc with mine, also need to look at ecu change plus mafless as not very smooth on std

hadn't noticed that either lol.

as said ditch the upgraded top mount and go front mount. it may be worth waiting and saving for ecu/front mount and getting it all done at same time.

but you will need an induction kit too, but selling the top mount on ebay should raise enough for that.

true, also fitting will be a bit more, but the gains are well worth it even takign that into account. so still a no brainer to me.
