It's fair to say that the difference between 20 and 25 engines will be very small. An inch of block height is not a lot of mass compared to the rest of the car, even if most of it is right over the front axle. You could estimate the extra weight if you needed to.

For the gearbox options....because the box is so much closer to the middle of the car, it probably will have little effect on the front/rear distribution also, even though the 25 box is nearly double the weight of the 20 box.

I know this doesn't really help!

R32 SEDAN with RB25 & R33 box. 1450kg total with driver and almost empty tank.

Only things that would effect weight from standard coupe are 17" gtr wheels, gtr bonnet, gtr rear hubs.

870kg front (959lb./wheel sprung)

580kg rear (639lb./wheel sprung)

There's a weight bridge in oakleigh that will do it for you for $20

    • If you like more modern stuff than the R series, you should check out a V37 400R, they are pretty mod friendly
    • Haha luckily we don't have emissions, inspections, or any laws against power adders here. They only thing they somewhat keep an eye out for are ridiculously loud exhausts. 
    • Just wanted to pop in an update on my setup. The CD swap has been great, I love the mazworks housing for the overall simplicity. I ended up sealing my trans tunnel with a thin sheet of aluminum reused some of the holes on the trans tunnel, and laid some window sealing EPS foam around the edges. Works great, really quieted things down and sealed up the car.  As for the power comment. Right now I am also running about 650whp. with the way the bell housing is attached to the face of the transmission I have zero doubts it would be fine, mainly because the input shaft and main shaft bearings are seated into the bell housing adapter. This means the load is NOT on the bolts to maintain the power, rather into he casing of the bell housing; Yes the bolts are doing some work there, but with both shafts locked in zero worries.  End of the day, the Mazworks solution is the easiest and safest. no need to take your trans to a shop to get milled perfectly, it fits with minimal clearancing, and you can use all your existing clutch and flywheel.  Driving wise the CD has been great compared to the big box, I'll probably swap my final drive at some point. The serial 9 shifter is gooooood, my only qualm is how tight it is, it takes a fair bit to get use to, 5th and 6th are a bit eh/hard to find at times, but maybe I need re-adjusting, and I think my clutch master is very tired and needs a rebuild. 
    • If you are keen, have a look at my build thread. Car is for sale for the right money or straight swap for a F80 M3 LCI.
    • Welcome mate.  No point in over thinking it, buying any one of those cars you mentioned is not a smart or logical choice with the availability of many "better" (re price to performance) cars available to you.  The heart wants what the heart wants, buy whatever it leads you too.
