Hello again,I just was wondering about changing my 2.6 to efi. :confused: Last owner the engine went,and secondhand efi engine put in.The efi taken off,old manifold with carb put on.I have spare head,gearbox and efi manifold.Are all heads of 2.6 the same?. :confused: I don't have ECI UNIT.What work is need to be gone?. :doubt:

the heads are the same.

What you need is....

Intake manifold,
exhaust manifold with oxygen sensor, you also need exhaust with under body cat, or something like that,
EFI fuel pump
Computer (of course)
Air intake (with the filter) is different to carby
Ignition coil is probably different to the one you have, and the dizzy (depending what was changed from this second hand efi engine) and transisitor,

I cant think of anything else atm, have fun.

u also need the plugs from the EFI car to plug into the ecu etc. you'll have to do abit of electrical work behind the dask soldering the EFI plugs onto the existing wiring in ur carby car. if u have aircon u also have to muck around with the wiring in the fusebox to get the aircon to work.

i think its worth doing the efi 2.6 is a lot torquier,
basically what they said above is corrrect, but any magna is efi so would have a cat in exhaust, also oxy sensor can go in anywhere in the exhaust b4 muffler, so dont need to change manifold necessarily- it might be cheaper to get it put into piping- thats just a hole drilled and a nut welded on, the sensor is about 100$. the computer is about 300$ for an exchange one and maybe 5-600$ for a new one if u dont have an exchange. basically u need to know what reference, load points the computer needs to read from, to control efi and connect all essential sensors. 2nd hand factory unit or 2nd hand aftermarket ecu and other parts could be ok if u know there history.

Thank's for the info,guy's. :D I was hopeing that i didn't to do things like fuel pump and all that electrical stuff. :shock: Need to think this over.

By the way,Altera98,what you mean by ALL magna are efi???.

i think its worth doing the efi 2.6 is a lot torquier

i wouldnt say that the EFI will make it ALOT more torquey.
specs: carb 1st gen - 83kw, 195nm torque
EFI 1st gen - 93kw, 205nm torque

but i would agree with the "efi is worth doing" part. will keep things abit smoother, better fuel economy and most problems can b diagnosed by the computer. it isn't too hard to do everything, its just time consuming. the hardest part is the wiring. take it to an auto electrician to do it if you aren't comfortable changing the wiring.

also, yes the carb magnas have the catalytic converter in the exhaust manifold in the engine bay. so if i want to go EFI, you'll also need to get a cat put in under the body in the exhaust system. could also be a good time to upgrade exhaust if u wanted to :D


so dont need to change manifold necessarily

the exhaust manifolds are different so you'll need to change them. and yes, need oxygen sensor

the exhaust manifolds are different so you'll need to change them. and yes, need oxygen sensor
No brendan. The only difference is that they look different and that one has a o2 sensor in it...

drill the hole, install a sensor and ur set for efi






PS: carbi + rebuild > efi with tired old engine

"carb manifold will fit however the bolt fitment for the piping to the CAI has to be converted to allow the O2 Sensor." - quote from mate that has sourced ALL the info for this conversion before.

is also illegal, but if that dosent bother u, it can be done.

sorry i meant all are ULP :redface:

my old 2nd gen efi was 98Kw , 205 Nm . anyway its the delivery of this system that sends a pulse only on compression stroke that gives really good low down pulling, so i reckon the curve would be better low down than the carb, they certainly feel way better to drive the efi.

Back again,what you guys think about this.I am thinking about putting on a Volvo 260 continuous injection(CI) .It is non computerise ,no ECU. Jeff next door used to have a Volvo 260.Can it run on my 2.6. :D

I don't mean volvo 260,the 240 2.1 engine. :redface:

sorry i meant all are ULP :redface:


the first TM's that were built were LP, then were changed to ULP later on. i have a 1985 TM, made in decemeber which is ULP. is lucky, one of the first to be ULP. but if his is a TN thats fine, it'll have the ULP head of course.

no idea if it will run hey. i know that starion fuel injection setup will work on the 2.6. no idea bout the volvo setup though... if it can be modded to work go for it i spose.

actually the old volvo 244, with 2.0 engine is very reliable and can be good for 500'000 km, thats why it gets used as marine inboard engine, but... the 264? V6 model did have problems with that mechanical fuel injection for one guy i know of at least.

it sounds like a lot of work to adapt it all to your magna for probably no real gain at the end, u could stay with carby and still do performance mods including upgrading the carby/s

You know Altera,it is too much to do! :nuts:It would a lot easier to use the parts off a efi magna wreck.

much better idea to use efi parts off a wreck :D

but hey, u could always stick with the carb like Altera98 said. that's wat im doing, and doing a few mods. this minor mods should give me even more power than the efi model, while hopefully drinking only as much petrol as an EFI car would. if u want i can let u know wat mods im doing... im doing it all on a budget of $600 aswell, but this dosent include any labour as a mate can do it for a carton or so :)

My TM is a leaded model - built Dec 1985 according to the VIN plate (but the reconditoned motor is unleaded)...


Anyone actually tried converting to EFI? i'm getting a wrecked tn/tp magna elite and want to convert my TM to EFI... but i wouldn't have a clue of what to do - especially with the wiring of the ECU... maybe if i had a wiring diagram of a TN/TP then it might seem easier...

What does the ECU control? (eg. why does airconditioning get affected?)

Thanks,
Bill
