Just replace the stock center diff with a spool and run 8mm pinions as spurs and make the holes on mount a little bigger so you can slide the motor outward a few more millimeters like I did with the early motor mount.
I can fit at least a 37t PINION with a 26t SPUR. I have gotten my MGT7 up to 140 mph on 8s with 37P/29S.

Here is a 139 mph pass. Check out my other vids too of this wonderful car.

I've bought this car to race in a GTe class that we'll have next year in our local track.
Mugen should recognize they failed in designing an onroad car with offroad gearing options. Know that they fixed the problem, I just don't think it's fair having to pay for this "upgrade"

but I would loose in cornering ability

and it's not hard to visualize...
Imagine a very tight corner... The rear wheels will have to displace more than the front ones since they're in the outer radius of the car pivot -- the front wheels. By using a spool, you'll be forcing front and rear to have the same displacement and the car will probably loose the front.
In fact, front and rear diffs also play an important rule regarding cornering ability as the outer wheels must displace more than the inner ones. In the other hand, front diff is not an issue and some pilots like to replace the diff by a blocked spool. Front wheels are important to pull the car and keep forward traction while cornering. It explains why we use thinner diff oils in the rear diff

Sure!

So how big of a pinion can fit with the updated mount?

Foam or rubber, you will never see a purpose-made 4wd on-road racing car with a center diff.

Well I think it may come down to personal preference. Some drivers may do better with the center diff and some with a spool depending on driving style.

Front spool
Hi there,
does anyone know which spool could replace the front diff in this car?

BTW is was an asphalt track.
Overall this is a well engineered but IMO a poorly packaged kit in desparate need of better instructions. For example, many parts bags have several sub packets. However, to complete most assembly sequences requires you to open just about every subpacket because the needed parts are spread throughout most if not all of the sub packets within that parts bag. IMO it would be much better to put all the parts needed for that one assembly sequence into the same packet - less chance of loosing those small parts! Some shout outs warning you that, for example, the center diff case is different than the F/R diffs as well as the correct orienations of certain parts would really have been appreciated.

Mine came with 600K for F & center diffs and 50K for rear diff. I've seen 1M (in my 1/10th cars), 2.5M, and 22.5M for the front diff. Those should virtually lock the front diff. I put a hybrid setup in my MGT7 ECO that was used by our local MGT7 expert in Brownsville to win the recent Serpent Challenge Electric GT race: Adam Drake's nitro MGT7 suspension settings and the rest is stock fluids, pistons, and swaybars that came with the ECO kit. Hopefully mine will turn as well as Doc's once I get a chance to get it out on the track. Adam modified the upper front arms to reduce the caster; however, I didn't do that yet til I get to run the car on the track.

Sorry, but after 30+ years of building and racing RC cars: poor instructions and poor packaging do not equal a PERFECT car!. Now that I've built a Mugen kit, I know what to look out for when building another. But I think this car will be easy to maintain (I've rebuilt it eough already) and should be awesome on the track if the results from Brownsville are any measure (only 3 ECO cars had 17 laps and 2 of them where MGT7s). In fact after the 2nd qualifier only one nitro car was qualified faster than the MGT7 ECO and it was a MGT7 nitro car.
