m22 4 speed and 3.08 diff behind a grey

[John253a]

anyone done this before, does it fit in factory tunnel of does it need to be cut
resion i ask
factory box is 2.98:1 first with 3.888:1 diff
m22 has 3.74:1 with a 3.08:1 diff
put the take of about the same a factory but less rpm on fwy

[John253a]

or a w59 supra box and 3.7:1 diff

factory is around 3450rpm @100km
m22 with 3.08:1 2750rpm (same gearing in 1st as std)
w59 (0.85 od) 3.888:1 2950rpm
                    3.7:1 2800rpm
                    3.5:1 2650rpm
                    3.08:1 2350rpm (same gearing in first as std)

What combo's are others running,(rpm at 100, and does to take off well, hp of motor)
as i dont see the 3 spd crunch box handleing any sort of power incress,
i would to keep the coloum shift, for the stock look, but i dont think it will happern.

when i get around to the rebuilt, im aiming for around 150hp mark, nothing to wild (i drive a 450hp car as an everydayer)
200/204@50 400/415 lift 110lc cam(very small custom grind), 6.5:1 comp, 465 holley, toyota blower @ 3-4psi, twin exhaust

On a grey motor?

Are you on the correct forum.    A grey is a very small motor. Have you seen the pissy rods in them. What about an old Toyota four speed if ya wanna keep the column shift. Why jump to supra when a standard celica box is way over engineered for a grey.

leave some petrol for us over xmas....

I'm with Ken,

"nothing to wild"  mmmmm me thinks not. I can tel you from experience, if you want to go any where near 150 with a grey you are looking for "wild" and wild sort of money.

I had an M20 with a 308 diff  in one of my Fc's and you need to modify the whole top of the tunnel if you don't want to change to a larger tunnel. They are a good highway cruising set up, but the celica 5 speed with the 308 is a better one.

Am i trying to chase to much power?
Ive only ever bolted one of theis on a stock grey with a small pulley on crank so around 1:1 and boy did it liven it up
Felt like close to 100hp

im aiming for all low end power, with low revs on fwy
the cam and blower i already have, i plane on driving the blower at 1:1 (the is blowers make around 1psi per 1000rpm)
a 200/204@50 is only a 17/60 cam very small and all low end power(1200-3800rpm)
i do plane on a port/polish of the head but nothing off the top
i currently have a set of extractors but I'm looking for a set of good myers pipes that wont break the bank
the carby i have a 465 and 350 sitting at home and plane on trying to one of them

i dont want to cut the tunnel/modify as i dont plane on engineering it, so what ever is on needs to be able to go back to stock.

'fe350chev'
what mdl 4 spd is able to run column shift, and who does theis conversions
i spoke to rodracks and he only does the ausie 4 spd
and there a few modifying the colum shift for a full syncro 3spd box

my only other option is the 148 as under the new law i dont require a engineers cert to install it,
  

[fe350chev]

I think you mean 149. With that motor you will get more power without a blower I think. Dellow probably have done four speed column conversions if u wanna stick with that. Parts all over for red 149. Keep the grey for changing back to stock

[fe350chev]

Nothing other than a grey is legal without engineers report now.

[FCRB26]

Wouldnt a 138 red be legal i have seen a few in earlly holdens still running stock front end and rear end and crash box ?

Think the 138 red came out in a turd runner (torana)

[John253a]

i have been told that the 138 red was optioned in the late fc
as my dad said his first car was a fc red
and a bloke i work with said he had one

ive seen no documented prof of this but being the same motor idd say no engineers is required either
i no of a lot stock/near stock 149 in fe/fc with no engineers and no problems

[fe350chev]

Do it then if ya can find one. Paint whatever you do in grey cops won't know  unless they are old

[John253a]

even if they are whats the bet they'll remember what a grey looks like
unless they still got one 

[fe350chev]

The 138 was only in torries and exported hq's and johns fc

No FC EVER had a red motor as standard, they are pulling your leg.
And don't think the cops are as thick as you make out.

The red 2250 motor as Deano said was in the standard Torana's it was stamped as a 2.2 on the block. The first red motors 149 & 179 started in the EH holdens all motors before this where 138 grey sideplates up to the EJ

As I said before I never seen any documented proof of it only have a few people tell me that back in the day they had red motors in there's, now it might not of been a 138 I never asked they just said red.
