GQ Dual Cab. TD42Ti with fruit.
My old turbo was a Garret 2860RS, generally regarded as one of the quickest turbos to get going low in the rev range, albeit with modest performance. And I reckon the EFR is about the same in terms of when it starts to spool up. After that no comparison.So after trying everything to get my 6758 to spool up properly under 2k I pulled it off last week and installed a 16g 6cm to test if the turbo was just too big.
What do you know the 16g spools up identical to the efr
So this leaves me with either the pump or the cam, I was actually making a few calls this week about sourcing a silvertop cam but if the above is correct then that will save me a LOT of headaches.
As for 16g vs efr the 16g has better torque in the lower rpms obviously but the funny thing is it seems to take more to get going hard to explain
