1,9 to 2,1?
Hello.
I am new to this forum so please forgive my ignorance.
I have a 1,9 GW (90 bhp, fuel injection) wbx in my oval. I would like to upgrade it to a 2,1 DJ.
Which parts do i need for this build? I am thinking stock DJ.
I just bought a 2,1 crank and flywheel. Do I need another cam? Can the 1,9 cylinders be reused? What else must I have in mind?
Thanks

Re: 1,9 to 2,1?
you also need the DJ cam (or a CB2252)
and the DJ pistons
cyl heads are different
1,9 cylinders are the same.
the 1,9 rod's can be re-used as they do not use the stretch type rodbolts
the injectors , ECU and Air mass meter is also different.

I believe I am already running the 2,1 cylinder heads, injectors, ecu and airmass meter so i guess I am on my way.
How about an engle 110 cam and solid lifters instead of the original setup? Or can I reuse the lifters with the engle 110 cam?
Thanks

Re: 1,9 to 2,1?
an w110 is not compatible with the small diameter hydraulic lifters ,
it will wear down due to wrong geometry.
and the w-110 would move the torque a noticable way up the rev's, making the stock ecu probably not provide correct amount of fuel.
look into a CB 2253 or CB 2254 cam
when swapping to a "bigger" cam like the w110 , the stock ecu should be replaced by a programmble one.

a 2253 or 2254 would also move the torque a bit
stock ecu's are limited!

Re: 1,9 to 2,1?
What would happen if I only swapped the crank?

Re: 1,9 to 2,1?
you'll get closer to a stock DJ

Re: 1,9 to 2,1?
piston height is different on the 1,9 vs 2,1 pistons so you'll not be able to use the 1,9 pistons

Re: 1,9 to 2,1?
How CB 2253 or CB 2254 cams work with stock digijet ECU ( DJ-version ) or which is the best cam/ratio rockers to get maximum power with stock 2,1 Digijet?
