*first would it fit?
*sec $$$$ whats it worth to the job.
*thr is the car worth any more with it?
*## is there a better way too go?
*#*reliability (will it go on that cool morning you need it)

boy Ive got headache .

cheers

Lot of related projects around, here one of 24V engine into a GTV which has lesser engine room space. The work is almost identical. The GTA engine has the latest electronics which cannot be applied in a transplanted engine, so an aftermarket injection has to be installed. For instance Autronic. Lot of qualified work to be done to get a decent result!

Will the car be worth more? Probably not, you are doing this for your own enjoyment, so if you do it enjoy!

I thought about it for my car until I found out what is involved. It would cost a huge amount of money. The sump has to be cut and reshaped for a start, then there is all the electrics and other fettling to get it in there. There is an issue with rocker covers and oil filler cap, also requiring welding things up. There would be lots of other problems to solve along the way as well, such as power steering pump and aircon compressor location. GTA engines here in Australia would be very hard to find and very expensive. Three litre engines from the 2000s GTV6s or 166s would be a little more common, but still not cheap and the power gain from those wouldn't be worth the expense in my opinion, especially with the loss of bottom end grunt you get with 24 valvers by all accounts. The only one of those I found had done well over 200,000 km and would have needed a rebuild to be worthwhile. Rebuilding a 12 valve V6 properly is not cheap, but certainly more straight forward. You would be better off getting a good 164 3 litre and using parts from your 2.5 for the conversion. The flexibilty and low down torque of the 12 valve engine is better suited to our roads and speed limits, I think. The 24s have to be wound out harder to get the power. Sorry if this sounds a bit negative, but I went through the pros and cons for myself and got my engine rebuilt in the end.

Hey there!

Great project; I have built two 24 valve Milano / 75 conversions for myself personally (one a 3.0 164-generation 24 valver and the other a 156-generation 3.7 litre 24v) and have been intimately involved in the build of over a half a dozen other 24 valve conversions... As Glenwood's representative abroad, I have also been involved in the build of over 20 such conversions (many of those big-bores from 3.2 to 3.45 to 3.7 litre 24 valvers...) Needless to say, I love these conversions.

Do a search - this exact same question was asked not too long ago and answered in detail... Consume these threads and if you have more questions, post again!

Having driven and competed in 24-valve engined GTV6's and having owned both 2.5 and 3.0 12-valve GTV6's all I will say is that the 24-valve conversion is a much different experience, one you have to try to appreciate.

There is just so much more top end power, it's smoother and if properly tuned there is still plenty of mid-range.

If staying under the police radar is is a consideration, a better solution would be a 3 L 12V which looks just like a 2,5 but has in moderately tuned form the same power as the 3L 24V. No outsider could say its a 3L engine.
In our racing series we have experienced that lap times of the 24V cars are still over ours with 3L 12V engine. For a road car this difference would be insignificant!

I agree, especially taking into consideration the extra expense for the 24 valve conversion. Power up high is OK when you have high speed limits like you do on Autobahns and Autostradas, but here in Oz with our low limits it is a bit pointless and a 12 valve car is likely to be quicker. When you say the 24 valve lap times are over the 12 valve cars Gabor, do you mean they are slower?

Yes thats what I am saying! A part of the reason is that we have reasonably good suspension and braking. Our forte is in fact fast tracks which are scarce in this country. Our best results are on the fastest track.
