lol funny you said that. There was a Ti at the shop getting an inspection today and I thought it would be a pain in the ass to work on the engine. Btw, do all Ti's have the electric fan?

Yes, as far as I know, every ti came outfitted with an electric fan stock. It's not so much that the engine is a pain to work on, but there's no way in heck you could top-mount a turbo.

Do not let that picture fool you.

There is quite a lot removed from the bay in that picture. Yes there is room to work, but not much in terms of room for turbos and such.

Notable items missing, washer tank, fan, shroud (which is huge), and airbox, which is also huge. Granted most are easily  moved or changed, them not being there at all makes it look bigger than it is.

Even though it is FI, it would be interesting to put an EGT probe on all 4 cylinder banks as I have a hunch that #3(and possibly 4) cylinder could be off on the a/r's given the intake manifold design. I don't see as much taper towards the end of the cylinders but I could be wrong. Good job on the fabrication though. What TB is being used?

It starts to taper at cylinder 3. The shop thats tuning it spec'ed a bored Passat throttle body. The entire setup is very overkill as the initial goal is "only" 300whp. We know the customer and he will definately get bored and want to turn it up so any future upgrades will only need a larger turbo, more fuel and possibly a throttle body swap rather than tearing the whole system apart.  The intake will work well, theres 11tybillion different opinions on plenum shapes and such. The only times Ive ever seen real world problems crop up are when severe edges/angles are used or if its grossly over/undersized plenum. We're anxious to get dyno results on the whole setup and it will be completed fairly shortly.

Looks awesome!

whats the volume on the plenum? I recall the s42 cars ran around 4litre or so?

Customer wanted a single TB, dont have to synch 4 seperate throttle blades, less expensive, no hassle of blending alpha n and map based input for part throttle transitioning for good driveability, list goes on. He's running stock cams so theres not really much reason anything else. One of the main benefits of ITB's besides throttle response is not having cylinder pulses from huge cams causing havoc in a post tb intake plenum.  Surprisingly as of late, well designed single TB intake manifolds have been making more power than ITB's in many honda n/a applications.
