eek EFII XR6 engine transplant into EF

hi all,

would really appreciate any information on work required or any additional parts required for a transplant between an EFII XR6 engine into an EF Falcon?

Will it bolt in?

Is there compatibility problems in wiring, gearbox, engine mounts etc?

Having my EF run on LPG, will this be an issue?

Anything else i should be aware of?

And finally does anyone have any contacts of who could perform such a job in Sydney???

cheers
Franky

you are talking about the same car, Xr's are just normal falcons with go fast bit's added to them. An XR6 engine is identical to what you already have except for some small changes to the computer, head, camshaft and a few other little things. It isnt a different engine with different mounting points or anything like that.

As for finding someone who would do the job, any garage would do the job in about a day.

Correct me if I am wrong but the only difference the two engines is that the XR has a different head, cam and computer the block is the same. So I wouldn't transplant the engine, just lift the head and get someone to reprogram the computer like Silverwater Automotive Services.

I have done a head swap on my EF. I lucked out and got I think an AU head as it had conical valve springs and smaller diameter valve stems similar to the EF XR head ?? I have had no problems with fitting or reliability of the head.

thank-u

excellent...

thanks for the details guys, im very new to this game. I inherited the falcon off my dad, of which was an ex sydney taxi :) lucky the old man took care of it though!!!

It's actually a true testament to the thing though, 742,000km's on the original donk, hasn't even changed a head gasket!!! The thing should come out and be framed :)

So its time to go....it was blowing some smoke the other day it definately feels like its running on 5 or less cylinders. I have trouble keeping up with Excels!!! :)

I've sourced an XR6 engine (from the list in-fact), i wouldn't mind an XR8 engine though to be honest - is there much difference between the 8 and 6? about 20kw's?

Another question, after the transplant (which i take to be bolt out, bolt in) what needs to be done? ie. paperwork? engineers certificate? reporting to rta? etc etc?


many thanks in advance...
Franky

coolies.

the XR6 engine im thinking of getting comes with an ecu for a manual transmission. owning an auto, will this cause a problem? will it matter?

i've been told that my std. ecu will run the engine, no probs, however im guessing the maps will be completely different to the xr6 ecu maps?

is the std ecu programmable? or will i require an aftermarket ecu?


cheers,
Franky

The computer is a small problem as the ECU controls the transmission shift pattern. The std computer can be chipped. Chip Torque plug in a module to the std computer that has the new maps on it tuned for your engine.

hmmm, an interceptor unit such as the unichip or chiptorque i suppose is not a bad option - as its then programmable!?!?

what other benefits do i have going to such a chip? over, say, a standard xr6 ecu for instance?
