Turbocharging TB42E

[Bigrig]

Cheers bigrig, did you change compression or any internals? Ive heard an xr6 turbs will go straight on a td42t manifold, did you have to change much? Any info would be great, sorry to be a pain.

No trouble at all mate.

I am machined the head to pull some compression out of it (went from 8.7:1 to 7.9:1) which allowed for a bit more timing and boost without pinging (around $1300). Nothing else changes mechanically, except the fuel pump (Wallbro High Performance to deliver enough fuel) and the injectors (VDO 660cc). All other mechanicals the same. The old ECU had to go also as it can't control boost, fuel injection rates, etc, but you apparently can have it remapped/piggy backed. I went for a Wold v500 at $2035 rather than frigging around with the alternatives.

Outside of other issues and items I spent on, I'd say around $8000 will see you throwing some serious output numbers ... and I mean 'serious'!!
