Hi all,

Anyone here register a new engine with WA licensing after an engine swap. I understand it is just some paperwork that needs to be done as long as capacity has not change as the form use RAC HP which is calculated on bore size & cylinders. Anyone gone thru this paperwork process & can advise me how long they will take before everything is good & registered?

Cheers,

KJ

Been through an engine conversion in a nissan patrol and that needed to be engineered. Got the engineers certificate, filled out the paperwork and then to the pits. Only took a couple of days for that and then 2 weeks for the paperwork to be finalised. When you go in they will let you know if they can get it through sooner.

as longs as its a direct replacement engine, ie 2 litre turbo replacing a 2 litre turbo, its just a form to fill out

going from 2 litre n/a to 2 litre turbo will require engineering

What about going from a 2.5 turbo ->2.0 turbo?

not sure, DoT would see this as a downgrade though so you may get away with no engineering best to give them a call

Was just food for though, but appreciate the help

Upgrade or downgrade requires engineering. Only a direct replacement of the same spec engine is a paperwork affair.

For everyone info, technically according to the paperwork, you can go from a NA 2L to a Turbo 2L & still have the same RAC horsepower as it calculated

RAC HP = (bore size inches) x (bore size inches)x cylinders/2.5

Horsepower - Wikipedia, the free encyclopedia

Bore size is same for 2L NA & Turbo. 2L EJ20 & EJ20T with bore size of 92mm gives a RAC HP of 21. Not much is it!

Strubaru & dtrally, have you guys done a direct engine replacement before?

hi kev
dtrally is doug from stechnic
we won't talk about strubaru's (chris) epic engine transplant...

lwhatever doug says on this matter you can take as gospel, he's the professional here I've only done same spec engine swap (well same capacity and aspiration) i never got around to doing the paperwork & now the stock engine is back in there

DOT will definitely be asking the question if its an n/a to turbo conversion they're not clueless
