I have managed to squeeze sometime to get in the garage today once I had done all of my chores, . I have been looking at the best positon for the turbo . There are only 2 positions I can see that will work as the engine department is tight on the exhaust side. I did think about trying to mount it outside the car but it gets difficult to do as the wheels will hit the air filter when the car turns. Can anyone for see any problems if i go for position 1 over position 2 from the following pics ?

Position 1


Turbo Position 2

The turbo in the pic is 90 degrees out of phase but I think everybody will get the idea of how it will be. This option makes it easier to fit the air filter , the chargecoooler pipes and the exhaust but will require the side bar to come out and a new one put in . The manifold will also be more difficult to make .

Position 2



Turbo Position 1

The manifold will be easier but the chargecooler pipe and the airfilter will take alot more work to fit correctly. The exhaust should fit too without touching the cycle wings, whcih was a big concern for obvious reasons.

How about putting it in front of the engine?

If you prefer Pos.1 then you can remotely mount the filter...

Mines in position 2 but as Steve says you could mount it in-front i considered it when i did mine.

If i was building a car at the same time it would go behind the engine with the passenger foot well moved back a bit you really need to get it as high as you possibly can to get a decent oil return.

Edited to add: you do know you can spin the housings by removing the locating pins (amusing that's a td04 turbo)

I thought I could Dave, cheers for confirming.

I did think about moving the passenger area back but was trying not to make more work for myself . If i go for pic 1 do you think the turbo needs to be higher?

I never gave any thought to mounting the turbo at the front of the engine, what rae the benefits to this?

mine was in front

here, look in turbo bec in archive too

If your sump hangs out the bottom of the car you should be able to get it higher than mine, my sumps level with the bottom rail.

In an ideal world the shorter the headers the better BUT its all about getting it to fit so compromises have to be made! in my case a scavenge pump.

And mines 1/2 in 1/2 out, exhaust becomes a straight easy run and most importantly the heat is outside.

Its much tidier now BTW, widetrack front gives plenty of room.

thanks for the pic Joe. I will check tomorrow to see if i have the room as that is also a possible option that would also allow me to run shorter pipes for everythiong elseas long as the charger cooler will still fit.

My sump is level with the bottom of the car too

Mark. I thought about half in and out but only have the standard wishbones so wont be able to get away with it without restricting the steering more. - looks good by the way.

I did think of your motor when that was suggested. You have no excuses now!

I would have to extend my headers a bit though to bring the turbo forward as it would be a bit close to the hoses to/from the water pump (and the thermostat). If I had to get oil back from it to the oil tank it may be a problem.
Bugger! See what you've done now, I'm thinking about it!

ETA - Apparently the synchronising of the exhaust and inlet pulses can be difficult with a twin (but there is a Hungarian drag team that seem to have this sussed!)

What about a booster cushion so I can see over the bonnet? It's bad enough with just the scoop over the TBs!
Still waiting for a reply from Hungary but the turbo appears to be off an Audi TT and they are getting about 220 bhp - which was nice!
