cams
 

can the cams from the mg zt 190 be fitted in to the zs 180. been told you can do this but you might need the ecu aswell. may be a cheaper alternitave to piper cams but with similar gains???

Cams and ECU are required, plus some other stuff too IIRC!

I think the 180 ECU should be able to handle the 190 cams,it can cope with Pipers afterall.(may need a tweak on the map).
Should be easier to install than the piper aswell as they are in a set position for fitting,aftermarket ones generally are not

also just read on xpf that the zt uses a larger throttle body than the zs. anybody heard this? i thought they were the same? that could be a gain in hp if thats true. would zt 190cams give as much gain as piper 270 cams?

TB's should be the same afaik, the 160 has a smaller one I do believe. I think the inlet cams are the only difference along with the timing.

who says the 190 has different cams .
I have the orginal mgr release brochure and it listed engine spec differences as better induction ,free'er flowing manifolds and exhaust and different map in the ecu .The zt only made 187 bhp ,a zs makes that with just induction and exhaust so what were the zt cams doing if it had different ones ........absolutely squat diddly is what,lol .
Throttle bodies are exactly the same.

180 and T16 tubby use a 56mm throttle body, 160 uses a 52mm, 1.4 uses a 48mm.

I only mentioned inlet cams as that is what I heard elsewhere and had little cause to doubt it, but you never know.

A friend of mine had 190 cams and ecu fitted to his 180, apparently they give a bit more low end torque but that's it

Alot of work for mot much gain IMO

SO why is their different timing tools for the 2.5 180 and 2.5 190?
