Does anyone know anything about putting the Nissan QR25 into a rear wheel drive car? What gearbox will fit, Clutch, Forward facing inlet manifolds? Is there anyone with experience in Sydney or Australia?

don't waste your time with this junk

Unfortunately I have to. I am building a car from scratch and the engine has to be no older than 3 years old. I wanted to use a SR20DET but my engineer cannot pass the car in accordance with ADR (australian design rules) I am a true nissan fan and can't think of any other engine that I could use that will meet Euro 3 Emmissions compliance! HELP!! Anyone? Any info on doing a RWD QR25? We dont have the Nissan Frontier in Oz we only have the x-trail.

just a guess but dellows fabricate all kinds of different bellhousings to suit almost any gearbox to heaps of different engines, maybe give them a bell and see if they can help you out there?

Thanks!! Have you got any contact details for them? Or know where I could find them? Just Googled them but came up with nothing!

another one to try is castlemaine rod shop they make bellhousings and adaptor plates among other things,

qr20 is better for the stroke as the 25 has huge issues as as mentioned is a piece of junk. Also you wont find an adaptor for the qr youll need one made up.

Hi Chuckie,

Good idea. In stock form, the QR25 is much better than the QR20 -- 25% more swept volume! If you are going to turbo it, well no worries, just use custom rods & pistons...

It seems no one has investigated which transmissions will fit (if any). Perhaps you will have to make a bellhousing adapter plate. Also in the Sentra it has fly-by-wire throttle, and it seems no one has back-fitted this into an older car.

Some information is here: Nissan QR25DE 2.5 liter Engine in the club Tech Section.

Actually a frontier of 05 or newer uses this type of engine plus I've heard reports of the ka transmission fitting as well. I haven't tried it but I too am thinking of doing this swap as well. People say its junk but they have been improving them and I've seen multiple people who have been successful with turbos and superchargers. I think when a pro racer uses one that's when people will stop saying its junk... I cant wait to get my hands on one.

they have been improved since the serious issues they had
I think they are post 07 but some tuners offered them with
sr20de cranks machined to suit which are full counterweight
and better for high rpm and I believe they where 2.3L.
Dont think these mob still offers them from lack of interest.
They are an ugly thing and many datsun folk have built L series
with the ka24de head in various forms and cost.
