Now work out your dynamic compression ratio
My static was about 12.9 but dynamic was closer to 10

I Must be doing something wrong
I don't get near those sort of RPM

They have it as a Hiace to A series adaptor (I think)... not a Datsun to Toyo thing... and not on the website
Reminds me... must order mine

Long time ago
I had my engineer who does such things machine , lighten and balance the flywheel
NSC573 from memory ... so SR N14 and 1.8 N16 I think they fit

200mm will work fine
Not sure you will get to 225mm
I did a Pulsar 215mm clutch on an A flywheel and that about max from memory
XT130 runs the same spline in 220mm
YN55 Hilux + YM21/30 Liteace are 215mm (TYC501)

I once got a quote for a custom twin plate with billet flywheel from Direct clutch for about $2k
Not really needed unless your over 500hp

Might pay to pop into a clutch guru for a chat

My orange 1000 coupe I have owned since about 1992
White 1000 coupe I've had since 1999
The caged 1000 coupe I got last year

STD deck ?
I've used 77mm Mazda pistons... but I think they are 28.6mm pin height
And 20mm pins

Depends how much grunt you've got
7600 redline in 4th with 205 tyre and 4.11 diff is good for 201km/h
But shift to 5th and the revs drop to 6500 and without any more grunt yes top speed stays at 200.... but with abit more push... 234km at redline.

Caddy did a modern concept car... the Cadillac 16

They also built some prototype OHC V12is in the mid 60's but never went to production

I wish
I have about 7 v8's... plenty of 4's...a bunch of 6's... but sadly no 12's or 16's yet
