Anthony Pllu 262 Posted May 15, 2014 Hey guys I have 2 FD ltds one is a efi250 one is a 351 clevo. Going to take 351 and box out and put in the other car. Both cars are running is there anything that i need to watch for? do i have to swap the diffs they are both 2.77. do i have to swap the fuel tank? as one is a efi pump one is the small pick up unit. is the loom from the ignition similar or shall i just swap over the whole wiring system. Is the cluster different? is the k frame different. not sure if the FD even has one. Going to start taking the 351 out more than likely tomorrow. will take a million pics so i have a idea on where is all goes back. any tips would be great Share this post Link to post Share on other sites
Anthony Pllu 262 Posted May 15, 2014 also is the tail shaft the same length? Share this post Link to post Share on other sites
Trev Vaa 1,185 Posted May 15, 2014 to save headaches swap everything bar the diff mechanically. wiring looms should be similar, but ive never done one on an FD. cluster will be different if it has a tacho. swap the tanks fixes the pickup issue, you will need to swap out the hard fuel line as well (where it goes through to the engine bay) and re run the fuel line anyway, they are probably different sizes, plus changing fuel line that old is probably a good idea anyhow. radiator etc is different so make sure you swap out all that. is the 351 car matching nos? if so maybe think twice before stripping it... 3 XTREME KARTS XF, bear351c and nickd reacted to this Share this post Link to post Share on other sites
bear351c 10,270 Posted May 15, 2014 Yep, what he said. ^ ^ ^ Everything fits. (Except fuel line is different.) Transfer all of it, up to the diff centre. Dash clocks as well, 6 cyl tacho/speeod will read incorrect. Tailshaft uni joints SHOULD be the same on the diff, but measure the caps just in case. Probably easiest to pull the whole wiring loom out, at least you'll have the right wires/connectors, saves heaps of time. Mark the wires as you disconnect them with masking tape and texta. Oil sender, Alt, etc..... Lots of photos is good. Post 'em up when ya get a chance. Share this post Link to post Share on other sites
bear351c 10,270 Posted May 15, 2014 Put the 250 in the other one, and sell it back to Grommet.... Share this post Link to post Share on other sites
gerg 10,871 Posted May 15, 2014 351 diff should be a limo, box should be C4 or FMX, so swap the whole lot as the kind lads before have already said. Easier to swap the engine and tranny wholus bowlus to avoid fucking around with lining up converters and flex plates and crap like that. Power steer lines I think are the same (according to some parts mobs) but you'll want the V8 springs and sway bar if you don't want jelly handling and the car sniffing the road with it's bum in the air. 1 bear351c reacted to this Share this post Link to post Share on other sites
SLO247 1,713 Posted May 15, 2014 Just swap everything. Imagine you are re shelling the 351 into a bare 250 shell with interior. Share this post Link to post Share on other sites
nickd 111 Posted May 15, 2014 is the 351 car matching nos? if so maybe think twice before stripping it... I've asked this question on xfalcon, if it was me I would strip the six cylinder and use for parts for the factory 351 which is rare as in FD worth more and will hold better value than a 6 converted 8 car. Too much stuffing around with EFI to convert to 8, to run a legally 1982 V8 in a EFI FD without engineers certificate it will have to be a 1982 shell (your being 1983) and on gas but that the 1983 model didn't come out in a v8 as will always have issues from Regency/RTA/RACV.

Ants 6,370 Posted May 15, 2014 No problems with rego on vic putting a v8 into an 83 or 84 xe/zk/fd. Just an engine number change, done it a few times. 2 Trev Vaa and XTREME KARTS XF reacted to this Share this post Link to post Share on other sites
Yonesy 1 Posted May 15, 2014 Can he retain the efi tank and electric fuel pump to supply the v8? (I'm doing a similar conversion from efi 6 to v8 in my xe! ) Share this post Link to post Share on other sites
Trev Vaa 1,185 Posted May 15, 2014 ^ not unless he changes the reg to suit carby fuel pressure, it'd be less dicking around to swap out tanks and fuel lines. Share this post Link to post Share on other sites
bear351c 10,270 Posted May 15, 2014 Agreed. Carbies run about 6-8 psi fuel pressure, EFI can run around 100psi. Will blow all the seals out of your carby.! Share this post Link to post Share on other sites
nickd 111 Posted May 16, 2014 No problems with rego on vic putting a v8 into an 83 or 84 xe/zk/fd. Just an engine number change, done it a few times. Wish it was as easy as Vicroads, every state has different laws especially Regency (Adelaide) are really tuff with these type conversions as you need an engineers certificate. 1 bear351c reacted to this Share this post Link to post Share on other sites
Anthony Pllu 262 Posted May 16, 2014 i would love to just fix up the 82 as it is all matching 351/FMX numbers, but the floor pan is gone the underside of the car is full of rust, if you jack it up you cant close the doors due to it twisting. the interior is a mess, everypanel needs replacing, would love to have a matching 351 but i have no want to sell it so im not bothered about resell value. already spoken to regency they said just to provide the engine number and the rego will go up a few bux, as its still a FD i can do it, if it was a FE then could not ill be pulling the 83 down to a bare engine bay as want to give it a paint first before the 351 goes in. 2 bear351c and gerg reacted to this Share this post Link to post Share on other sites
bear351c 10,270 Posted May 16, 2014 Sweet. Don't forget piccies..... Wish it was as easy as Vicroads, every state has different laws especially Regency (Adelaide) are really tuff with these type conversions as you need an engineers certificate. If the car came out the factory with a V8, it's pretty easy to do engine swap. XF/FE didn't, so you need an engineers report. Share this post Link to post Share on other sites

Anthony Pllu 262 Posted May 16, 2014 just rang regency again and they said that must have a min of 286x24 rear vented dics to clear for a 351 conversion in a 83. other than that nothing just a MR7 engine change form at motor reg and done 1 gerg reacted to this Share this post Link to post Share on other sites

nickd 111 Posted May 16, 2014 If the the FD 351 has rust you've done a great decision on another body, use everything from the V8 body to put onto the EFI body car example Wiring looms/dash/diff/petrol tank/ etc. Best of luck with it all. Share this post Link to post Share on other sites
Anthony Pllu 262 Posted May 16, 2014 yeah will start on it tomorrow as the 250 just blew a P/S line and pissed fluid all over my driveway and down the road so pulling it down now. Share this post Link to post Share on other sites
gromet88 3,042 Posted May 16, 2014 Sweet. Don't forget piccies..... If the car came out the factory with a V8, it's pretty easy to do engine swap. XF/FE didn't, so you need an engineers report. and good luck with that. regency dont even pass that now unless it is way over engineered. had a mate of mine want to do a v8 convo on a xf ute, regency said no. so he questioned and looked into it alot more to find that if he bought one already converted interstate, with all the paperwork, it can be transfered to sa. work that one out! so thats what he did. still got it too, and sa rego'd!

Well again, it had been sitting awhile, guess it got brittle over that time. As everyone has said, make sure to take lots of photos. What colour you painting it?

Anthony Pllu 262 Posted May 16, 2014 thinking just another coat of white, i have thought about a black bay tho. yeah the line has split next to the steel cover on it. ahwell have to get a new line for the 351 anyway but was kinda hoping to see if i could use that one to save myself $109 Share this post Link to post Share on other sites
