2000 s70 engine swap from nt block to turbo block

switzerauto · Post by **switzerauto** » 01 Apr 2014, 14:18

I am doing an engine swap long block only, the car is a non-turbo engine code 61, S70, 2000 FWD. The used engine I sourced ( very few used blocks around ) is from a Turbo S70 Engine code 56, 2000 as well. Apart from the slightly lower compression, I can't see any major road blocks to doing this install. Has anyone done this same swap and if so what performance differences did you see after your were done? I am not far enough in to see if there are any sensor differences. Will there be any engine management issues? Tx Mark Please email me so I can see you are posting [email protected]

Why not get the whole engine including turbo, ECM, intercooler, and related turbo components to turn your car into a turbo??

I have never done it, but I can't see why it would not work.

I've done it. It's a pain in the ass.

Which part? Turbo head on N/A block or N/A to turbo conversion?

If the turbo conversion, then yes.

You'll effectively lose about 10-15 percent in power and also a comparable rise in fuel consumption if you don't put a turbo on this motor. It won't be a pleasure to drive any more with around 110KW (150 hp) and a poor bottom end torque curve due to 4 valves per cylinder working with low swirl intake stroke.

A non turbo has around 210psi of cylinder pressure with 11 to 1 compression ratio.

A turbo motor has around 160 psi of cylinder pressure with 9 to 1 compression ratio for an LPT motor and even less cylinder pressure from a HPT motor (2.3 litre)

You will have some minor plumbing issues like coolant return and oil return lines to block off, but that shouldn't be too bad.

Is the ECU going to map fuel correctly with a different compression ratio? In theory the MAF should handle that but you know what they say about theory and practice.....
