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.   :D 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....
:D

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  :D

[fe350chev]

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

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.

R u a copper  :D :D :D

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.
