R33 Series 1 Engine, Swap Or Rebuild?

[WMDC35]

you can use all the original bolt ons from the s1 to the neo, you'll need the neo CAS and swap the wiring, you can use the s1 coils on the neo but can only line up 1 bolt, if you were set on doing it that way you could bodge up a tab the holds the other side

otherwise if you can find a low k tidy s1 or 2 would make it easy for straight replacement

the neo CAS?? mind edcuating me there?

could i "theretically" use the s1 rail on the neo engine?

and i assume a series 1 and 2 are exactly the same besides some loom issues (ie coilpacks etc)?

[WMDC35]

the neo cam angle sensor is the black plastic cap type which has a different drive to the 33 alloy type, the wiring is just reversed (mirror immage)

just use the complete 33 intake

s1 and 2 same, everything will swap from the s1, there is a late s2 which has the neo type cas also

so in short, ditch the loom for whatever engine im using and use existing loom and it will be plug and play really?

thanks for that info, major help!

dont think ill be able to afford a neo engine as their in low to mid 2thousand yet a series 2 ive been quoted for is 1700 from flywheel forward so i might go for the "cheaper and easier" option.

but again thanks for clearing that up, will make everything a lot less stressful!

so much knowledge base on here i feel like a massive noobie
