v8 supercharge engine swap

[Ronsta]

Hello, I am looking for some help and direction, I am currently working on a project car that is need of an engine, I am thinking the 4l supercharged v8 from an x308 on a manual gearbox ticks many boxes.

Now has/know anyone how has transplanted one of these before or can point me in the direction of a forum that may have.

Things that concern me are;

Will I be able to, if remapped use the cars standard ECU? I intend to remove the autobox and the cats, or will it spaz out and go into a failsafe limp home mode or will I have to but an aftermarket ECU?
Is the car transponder locked will I have to use the ignition barrel and other components from the jag, again is this another problem I can get around with an aftermarket ecu?

I don’t really want to go down the aftermarket Ecu route I am interested in this engine becuse it meets my power requirements in standard form I will fabricate a free flowing stainless steel exhaust and add a huge induction filter and have the engine mapped but more for the noise than the extra power.

If anyone can help I would be grateful

As the engine is going into something else then no problems

Will not be able to use original ECU, will have to be some thing else that only drives the engine, not talk to gearbox ECU etc

You will have a hard time re-using the exisitng ECU as half of it will be missing i.e. the gearbox and you will remain in limp mode for evermore.

I have used an Emerald for my XK with a dodge viper 6 speed manual. You will have to ditch the coil packs using this type of ECU unless you pay big money for a Motec. Whats good about the Emerald is it comes with 3 maps installed which you can switch through whilst on the go. e.g road, fast road, race.

The original Jag ECU is very restrictive I found it easier just to bin it, of course with the XK this did have a few other probs like having to re-do the instrument binacle but there are ways and means.

One other route if you was adamant you wanted to keep the pos jag ECU is give Elite a call and ask them to let you have one of there little black boxes to fool the ECU the gearbox it is still there!

Ok I have options that's great, the emerald looks good that seems to be alot of ecu for the money, in fact I may well give them an email, just out of curiosity when you ditch the coil packs what do you do for ignition? a wasted spark set up?.


not into an x-type nothing that civilized I am afraid I may put one in my track rat Nissan 200sx

I changed to just 2 coil packs and used plug leads all sorted by Dave at Emerald, comes with all wring plugs easy to incorperate into your new ECU

Easy!
