how easy to fit a 3.0 or 3.2 in place of a 2.6, what bits would I need off the donor car to make this work, anyone tried it?

[pauls]

Hello mate have a read through some of the posts that i started i asked the question a few months back

not sure what you mean by easy, but you need bare engine and swap all running gears to donor engine that  it really

[2woody]

3.2 is a great and very easy swap for a 2.6.

you'll need the engine and the engine controller, complete with the key chips and transponder.

and also the differential if you feel like it.

I've never seen the need to swap the gearbox, mind. both of the cars I've done have lived very well with the original 'box. Even on the track.

I might entertain the idea if towing lots, though

[Darth Loo-knee]

If you have a 2.6 already the newer 3.0 engine will go straight in as it has the reservation for the coil packs 

[2woody]

.....but that would mean running the 3.0 on either 3.2 or 2.6 map - less than desirable

If an auto, probably worth swapping the gearbox, as presumably you want the 3.2 for the extra power, and I can see the AR25 struggling after a while.

When running closed loop there shouldn't be any difference surely there may be differences during warm up and at WOT though.

[2woody]

yes, quite a lot of difference.

to be very basic about it, there's 40 horsepower of difference, so you're going to be expecting the system to adjust for all of that. It may have the capability of adjusting for 5 if you're lucky.

sorry

The ECU takes the reading from the MAF to tell it how much air is going in and then adds petrol to achieve a stoichiometric mix. If the fuel map runs out at too low an airflow then serious lean running could occur.

Statements I have seen on OOF in the past are that the ECUs for the smaller engines have a fuel map that IS suitable for the larger engines.

Would be good to get the view of TBE & Darth Looknee again

thanks for the replies so far good info.

thanks for the replies so far good info.

Worst case, drop a 3.2 in with a 3.2 ecu, and the car won't be any wiser

I've been mapping engines for twenty years now, both in the aftermarket and for motor manufacturers and have yet to come across a map for one engine that could be used in another.

3.2 engine with the corresponding ecu is definitely the way to go.
