1. I think the date on your computer is wrong or in wrong format.
2. Have you looked at davids FMIC thread i am sure this will give you some idea, although his is diffent/older car.
Quite alot of work i think.

to answer your questions.
1. pc clock isnt wrong, its a common error on scoobynets BB software.
2. have already spoken to David, hence the post for my99 type info.
3. Am not a huge fan of the soft silicone hoses, my opinion being that they will expand and contract under use. Purely my opinion. Also the polished staniless ones look better

there is NO point in reversing the manifold unless you are looking for more under bonnet space, and from my knowledge of your car, you dont need it.
You will not notice a difference due to the reduced volume of the pipe work, you will create problems rerouting pipes and you will lose air con which I assumed you had.
all in all, I have the option right now at re build time, and there simply arent enough advantages to make it worthwhile.

depends on inlet, and throttlebody being used... you can turn them around without doing what I did!
I Promise, as Ive seen it done!
Adam - Shut up... your only saying that becuase you havent done it

I agree with Adam, Whats the point??? Its not going to gain you any power at all IMHO, so it is a waste of time doing it ( You are doing yours for slightly different reasons David, and strictly speaking you arent 'reversing' yours ). All this Bollox about creating lag with long pipes.. Have you any idea how much air the turbo is pumping?? Makes the volume of the pipes seem very insignificant.
Certainly a certain black cars setup was very impressive, but I can only have nightmares thinking about the price of that manifold, let alone the rest of the engine.
Personally, I think the Pace setup is the best of both worlds. Short pipes ( miles shorter than any other FMIC std inlet setup ), and it does seem to work pretty good at cooling too ( fitted to the legacy )

Reversing the IM is a fair bit of work, but not too bad. Mine was done, more for "space" issues, than lag, but whilst it will make little difference once you are on boost, it will help a little lower down, where rpm's/gas flow is low.
It doesn't have to cost much. Mine was expensive for other reasons.

the expense I refer to is air con, which to me is a valuable luxury.
Mark you dont know that there is an improvement lower down, it surely is a guess as you havent tried it both ways have you?
therefore any expense plus the cost of aircon is unlikely to be worth the possible improvement in low down pick up.
If I wanted to do it, believe me I would do the swap, but aircon is too big a price to pay for very little if not nothing in return.

Lose the PAS??? Call me a wimp, but I dont think so. The std PAS, on my legacy at least, has excellent feel, and makes maneuvering at low speeds a doddle too. Why would you want to remove it, thats just plain daft. Do you see many Rally cars without it. This is the new millenium, unassisted steering went out with MK2 Escorts and Minis. Next someone will suggest fitting a set of downdraughts to the car, and wind up windows.
As for air con, You may save some weight by removing, but personally, if my car was fitted with it, and it wasnt in the way of any future power enhancing mods ( that doesnt include a reversed manifold )I would leave it well alone. Unfortunatley, mines a UK, so doesnt have it. The car is like a bloody greenhouse in the summer, with no sunroof either.

Whats the big deal about losing the air con its only 'hot' and air con worthey for about 2-3 months of the year.... and even then its raining..!!
Plus people would by the air con system for nearly the price of a front mount anyway or there abouts, well may be just the intercooler..!!

What a wimpy lot
My car comes standard with wind up windows thanks, no central locking either (how hard is it to turn a key ffs ) Air con is only for fat sweaty blokes (and birds) Don't you want to hear that exhaust burble through the open windows anyway ?
Once you are rid of all that weight, you don't need the power steering either
Rally cars are different, lots of lock to lock stuff. If you drive a good handling road/track car properly you don't need much steering input, throttle control does away with most of it.
Stop pampering yourself and go fast instead

Not pampered enough, I just got older and wiser, and stopped driving bits of **** ( not meaning your car, by any means Andy, but other cars I have had the misfortune to own/drive in the past )with no extras some time ago. Nowadays I want my performance, with all the creature comforts too.
If I was bulding a car, purely for racing, then I would have no problems removing all those extras, but any car I have, will be driven on the road, so I want to enjoy driving it slowly, as well as fast.
In the same sense, people may consider turbos ruin the response/driving experience of an engine, and buy silly cars that need to be thrashed all the time to make them get past 20mph. Again, WISE UP, we are beyond 2000. Turbos rule, what easier way is there to get loads of power, and driveabiltiy, and fuel economy???

No way, We all need bigger turbos, or maybe just more of them.
I simply wouldnt own a non turbo car anymore...unless I was going to turbo it.
Id also like to have a go at one of these new centrifugal turbo style superchargers.

Hi guys,
a rare and brief trip into the technical forums for me.
My engine is being rebuilt and im looking at getting custom pipes made for my aps front mount to replace the silicone hoses.
But another cunning plan i had after talking to david wallis was to reverse the inlet manifold and therefore reduce the length of the intercooler pipework.
Can anyone advise me of whats involved in doing this on a my99 sti5 and how best to go about it, some pics would also be gratefully received

Silicone hoses expand?? Is thet very slight expansion that might occur really going to make a difference?? NO, They arent going to inflate like balloons or anything, and do allow the engine to move much better then a more solid installation. Stainless/Alu pipes will also soak up/retain a lot more heat than a silicon pipe ever will.
Regards the inlet reverse, I think the only problem really as fitment should be the ISCV. It will totally foul on the PAS if reversed. I think that is a reason why David decided to cut and weld a new hole on his.
