hey hows it going

i was wondering if anyone could help me to get a good idea of the job involved as i have a vs ute and a nissan skyline with a rb25det and wanted to know how hard it would be to convert the motor to the vs ute and what would be needed for the job as i havnt realy seen it done before. all i know is that a vl crossmember shoould fit in the vs and that the wiring will be a bit job i intend to also use the skyline gear box and it makes it easy for fitting then only needing a custum tail shalft. can anyone help in letting me know of anything else ill need for the job to be completed with the least amount of hassle

cheers

New fuel pump, wiring loom changes, radiator changes, exhaust mods etc. Conversion has been done a few times

im currently fitting a rb20det into a vp for the simple fact i had a ute with no motor and rb20det sitting there. use the vl crossmember with one vl engine mount and one skyline mount. fit the commodore crossmember to the nissan box and elongate the holes and it will fit. does require custom tailshaft. use a vl powersteering pump and vl power steering lines. one of the supports from the engine to the bottum of the gearbox needs modding to clear the steering rack. rad hoses are also hard as the commodore has narrower engine bay so standard skyline ones hit but you can just use a vl radiator.im currently fabricating allow hoses so i can run them where i want. i also am using the commodore alternator so all the existing wiring plugs back in. doing the clutch gear is the hardest. is yours auto or manual and whats its gonna be. my issue is that my vp was manual with a cable that pulls and the box is hydraulic with a slave that pushes which means modding the pedal box to accept a hydraulic push type setup and you are restricted badly by room issues.then just simpler things like fuel pumps but commodore pump will handle a stock rb engine. then theres FMIC and piping which is not the easiest and ive also put a engine oil cooler in the front with braided lines and its all a bery tight fit. all in all its not as easy as i thought but is doable.

Fuel pump will not swap over unless it is aftermarket in the Skyline already.

Definitely need a new exhaust to the cats but a 3" exhaust for the whole system would be better.

im using a manual and the vs ute was origanly a manual car that could be an issue with the clutch. i was going to try use as much on the parts from the skyline as i could just for the fact i know it can handle it all, wiring issue shouldnt be a problem as im a sparky. with the vl power stearing that should all fit fine in the vs wouldnt it. what engine oil cooler did you use you wouldnt have a few photos of the job that you could send so i could get a better idea

honeslty. i'm not a fan of commodores.

but if your gonna do it just use the standard v6, get a turbo/twin turbo setup, exhaust and a good ecu should see you pulling some good number, not to mention the extra torque and ability to run a bigger turbo and still be responsive.

i'm not biased either i drive a gtr. just thinking by the time you do the conversion you would end up with better results and a more factory looking finish with the v6
