Thread: Possible engine upgrade.

The factory turbo engines has oil coolers that squirt oil under the piston, a different rocker cover and oil filter setup.

The oil squirters stop the pistons from melting at high EGT. You dont need them, but will mean you can tune it to go harder.

You will need to modify your exhaust, your intercooler piping. Don't think you'll be able to re-use your clutch or alt without machining up an adaptor.

Not sure about the turbo.. may be a little small and not have to top end.

Not sure how much a turner performance head is, but converting to a 4db1 will cost a lot.. (and be worth it IMO ahahaha )

Got a quote for head replacement and all that entails at $5187, so already looking at a large figure, whatever I do. Though, that may also cover the clutch slave cylinder replacement I'm having done as well, I have to check.

I wonder what the market is for a relatively low-kms 300tdi sans-head? Already looking at ways to recuperate some of the cost. hehehe (kill me)

diferent strength crank, pistons and rods.

not essential but reccoemnded if your going to give it a good talking to.

Thats ridonkulous, a head is less than 1k with fitting kit plus half a days labour.
Even if you factor in new hoses, t/stat etc it wouldnt even cost 2k.
Its an easy straight forward job with no special tools required.

I suspected as much.

Has anyone tried this route with any success, or alternatively going directly to a supplier?

Ok, so I'm going to have to find a reliable mechanic, and ideally, someone who has either done one of these conversions, or is capable/knows what needs to be done.

I haven't had much luck with mechanics of late. Either the work isn't being done properly, or they're trying to rip me off.

Anyone asking over 5K for a tdi head swap is ripping you off.

I'm out of the country, so I still have to confirm, but the diagnosis of the head only happened once it was already at the machine shop, and also I'm pretty sure he's factoring in the clutch work. Regardless, I'm not getting anything done for now. The truck is coming back home and I am without a car until I figure out what to do, and who to do it through. Ugh.
