172 and 182 engine

[FlansS14]

What is the differance in the two engines. obviously the power but is this just because it has a differant ecu mapping or does it have better internals...

im gonna do a engine swap so which is the best. value for money ect

There little difference the 182 has a different intake and exhaust manifold but its not a huge difference. The ECU map were chnaged but just to up the fueling to compexsate for the better breathering etc the intake and exhaust manifold give. Also the cat is bigger so less restriction there.

If you can get hold of a 182 engine for a little extra go for that but its not worth spending much doing it.

intake manifold is the same, why do people keep saying they are diff!?

 

[Fred@BTM]

same thing pretty much

same engine really.... the heads were different from the early cup cars to the later 172/182 with smaller exhaust ports....

 

[FlansS14]

cool, thanks for that.... the engines seam cheeper than a williams engine n i don't thing n e one has put on in a mk1 valver but corect me if im wrong... So wats best for modding... i got exhaust decat... ect but who does good re-maps....

didnt the mk1 172 have a different head ? big valve head?

 

[Fred@BTM]

i think it had larger exhaust ports

 

[BenR]

earlier 172's until about late '02 had the sport head casting, with larger exhaust ports which flow much better. THe later 172's and 182's/cups have a head based on the turbo casting, much smaller exhasut ports which flow about 20% less. The valves/cams/geometry is the same.

But cnc programs for the 182 inlets seem to be marginally better.
