fn2 vs dc5 engine

[bhp-mad]

hi all, whats the difference in the engines fn2 = 200ps and dc5 = 220ps??

 

[Chris.]

Cams, mapping, exhaust IIRC.

 

[bhp-mad]

Are the cams able to be fitted into the fn2 engine??

 

[Ed]

Yes

On top of what Chris said: compression ratio, inlet manifold, throttle body (diameter and DC5 is cable, FN2 is DBW), DC5 engine doesn't have balancer shafts on the oil pump, FN2 does, DC5 doesn't have a MAF sensor where the FN2 does.

Yes you can fit DC5/FD2 cams to the FN2, but you will 100% need to have it remapped.

Are there much gains to be had from doing this?

so looks like the fn2 engine need alot of goodies to get the extra power out of it..

 

[Hazz]

Not really.

I put the FD2 cams into my EP3 (now walkden's), made about 10bhp more. They are a nicer cam though, a tiny bit more like the old B-series changeover... a little less cam on the economy cam and a little more cam on the power cam.

Walkden with another EP3 :lol:
I didn't realise the FD2 cams where more aggressive, makes sense though thinking about it. Is it a big job?

OP you have it mapped already?

 

[Hazz]

It's a fairly big job yea, half a day to a day's labour.

I was getting my timing chain & tensioner done so I thought I mayaswell bang some cams in at the same time too. I was a little bit dissapointed with the outcome, but it was a nicer drive.
