Hey

Thinking of upgrading the carby on my magna to one of a xf falcon

problem i am facing is my car is automatic so therefor has the thing on the carby that tells it when it shift gears

if i got the carby from an automatic xf falcon and just hooked its auto thing up would that work?

or what other ways besides a conversion is there to fix this?

I THINK it should be alright, the thing your talkign about on the carby is the TPS (Throttle Position Sensor) i think, but i dont think it has to much to do with how it changes gears, that just determines whether your revving the car hard or not, the TPS should be the same sort of thing either way, so i think it should be ok.

Speak to TM-SE-RED, he will know...

TPS does affect gear changes... also lets the trans know when to kick down too...

my TPS was out and it would not change gears correctly.

thought this post woulda been concluded by now. so i'll answer it and give you how to do it.
Yes it can be done. how? well for starters, you may as well buy a complete carby on manifold from an auto cause A the manifold has to be altered, and B you need the TPS from the old carby. the TPS is on the opposite side to where the acc connection point is. thereby allowing the tps to sense what revs the car is at there by informing the automatice ecu what gear to go to, and when ure in a gear, and hit the throttle to kick it back a gear, what revs to keep it at and so forth.
To allow for a different carby to work on your car but keep the car automatic, you simply need to replicate the tps and acc setup from the solaris carb (your stock one) and make it work the same on your new carb.
basically just rip the carb on manifold apart to pieces. get your new carb, and adapt the tps/ accelerator line to your new carb.
simple as that. As for finding someone to do it if your not confident enough, well you'll have to search around, as some places dont wanna do the fiddly work to make it happen. or do a shotty job, or try to charge the world, but it can be done. im prob doing it just to get a fraction more power with a 36/36 weber just b4 i stop mods on my car. if you can wait i can show you how. if you can't, good luck.

ive dont it from start to finnish, i was the one that did it on tm-se-red's (brendan) car.

i have since found out that its probably not the best carbi to use, the old cortina model webber is much better. same deal tho.

ill send you a PM

I have no intention to do it anytime soon, I only today got the urge to add power windows to my car, and finish that, so I doubt i'll be doing the carb soon.
Also ultimately due to the direction of the engine, no carb is gonna be superior except for the original becuase the float is designed differently. I was the one who informed Brendan on that carb, and only after hearing it from a carb specialist, who had a guess at what would work, had never upgraded a magna carb before.

kool, yet why the cortina isnt that one a 2L webber, i have the cortinas webber sitting around 4 feet away

Edit: came in a 4.1 L aswell, hopefully picking one up this weekend

finaly genna try to get this done next weekend, my carby is realy gone, flooding all the time, and the neadle and seat, and choke ect are fine.

so genna grab myself and xf carb later this week, i herd someone on here say a gemmi adapter plate for the webber can be drilled to fit the magna, just wanna confirm it

i have a pic of TM-SE_RED's carby i can see its tps yet if his car is still auto would there be anychance i could get a picture of how the tps was modded to suit the magna plz?

thanks all

he has manual, always has. no-ones done auto carby upgrade..... point of this thread....

my car is manual, only the best.

my car isn't that noisy... although my car at 2000rpm would be around about a drag car at 6000 lol. ok, maybe 4000. it's all good now with the middle muffler.

hey notorius, i would recommend getting the XF weber rebuilt and the jets changed. it WILL overfuel at idle (which means smaller idle jets. in there at the moment is a 50 and a 55) the fuelling jets should be changed aswell. primary is 135 and secondary is 220. the 220 should be changed to a 160. this has gotten my car fuelling pretty much right. but wen i go and get it tuned properly we'll b swapping jets every 2 mins to find the best one. jets are $9 each (u only have to buy 2 idle jets and the 1 secondary (160) jet. rebuild kit i got from the carby shop for $55 which included EVERYTHING.

can't really help ya with the TPS auto stuff... mine was a plug and play activity (kinda). damn i love manual.

notorius

k, thanks for the info on the jets, that preobley woulda annoyed me for a bit later in the week till i relised, and as for the tps, looking at it i think i can mod it to the peddle itself

ill ppost how i go on sat or sun

does anyone know how to modify the tps to go onto a cortina 2 ltr webber?? i have had a look at it and just ended up confusing myself... :nuts:

notorius
22-02-2005, 08:26 PM
i also have a 2l webber from a cortina in front of me, im thinkin its a tad to small for my 2.6 astron,

yet moding the tps looks like it could be a ***** or pretty easy

it may be possible to relocate the tps on the carby to were the pedal it self is some how mounting it and useing some sort or plate or whatever to push it down/up depending on were the peddal is

or there may be a way to mod it to the carby

its going to be pretty hard mate, the adapter plate is fairly anoying to make but making the TPS fit sounds even more challenging, ive tried a few time on mates cars to do TPS's on different TBs but couldnt do it :confused:

sprintsells the adaptor for 34 dollars. its just a webber to sigma 2.6 adaptor plate.. saves making it.. but then i am just lazy :badgrin:

turbo_charade
23-02-2005, 08:22 AM
but is a sigma carbi the same? and there is no way it would flow as mad as my version of the adapter plate :cool: the whole manifold was flown out

lord_davros
23-02-2005, 10:56 AM
dunno but its just to adapt the webber to a 2.6 ltr manifold..... it worked well on my old sigma and it fits nicely on my magna. just dont know how to modify the tps for it

notorius
23-02-2005, 12:35 PM
just dont know how to modify the tps for it

been lookin at it then back and the webber all nite, trying to work out how to do it properly, still kinda lost, genna play with a multimeter try to see what stuff is coming outa those wires and see if i can adapt a webber tps to suit a magna instead

lord_davros
23-02-2005, 06:13 PM
cool.. would love to hear how you go with it... but do webbers have tps's???

notorius

the webbers of an xf AUTO falcon im pretty sure have a tps like device, yet its only got one wire for it or 2, not the three the magnas have

im not sure about that becuase if the auto XF falcons used the non electric auto (hydrolic or cable) then they wont have a TPS either

i should find out sat if i can make my magna work again

lord_davros
25-02-2005, 12:13 AM
ha!!!!! here is me thinking my magna was quick!!!! i got a brandnew carby from a salvage yard (bargain $30) and put it on.. but while i was taking the old one off i realised that my secondarys were never opening due to cracked diaphram... teee hee now it actually goes well :badgrin:

notorius
25-02-2005, 01:03 PM
lol, alot of ppl i know (outside AMC) have 1st gens that dont have funtioning secondarys
mostly due to seized parts, or vacume leads

my mates 1st gen has 2ndrys that open and it was the same with mine and 2 others, yet the dont have the dash pot pluged in, the engine just sucks so much it pretty much pulls em open under full throttle

Terrorsidic
25-02-2005, 01:20 PM
the secondarys is when that little ECO, with a giant X thru it, light comes on?

cos if it is, it doesnt come on nearly enough as it should :badgrin:

notorius
25-02-2005, 03:51 PM
no, thats ure econimy switch, mine never lights up lol ceptt when starting

Terrorsidic
25-02-2005, 03:56 PM
yar mine only comes on when i put the pedel to the floor, which doesnt achieve anything other than the car revving lots while it takes a few minutes to decide what gear it wants :(

Gav
25-02-2005, 04:54 PM
Mine only comes on when there's a transmission fault, or whilst the car is starting.

BCX7
26-02-2005, 12:13 PM
no, thats ure econimy switch, mine never lights up lol ceptt when starting

you can adjust that if you want to... so it comes on at least when your flooring it... i was gonna change mine to "FUN" cos mine comes on when i'm flooring it (meaning i'm having fun!!)

i'm currently restoring my elite 85 auto (obviously) and the carby has had it , i live in sydney and simply want to get the beast running. i want to keep it nice and simple and am wondering if my best bet is to just get a reco or to repair my old carby? i have it removed and am ready to roll but need to find out how and where i should go within greater sydney i live on the north shore. i am in situation where if i dont get the car running i will lose it as my body corporate is now startting to threaten to impose a fine. ($5500) which is just a tad bit over what the cars actually worth. prepared to spend as much as it would take to restore her as it was a family inheritance and i hold great value to her, not to mention shes in an awesome state for her age. cheers
