goes well for a 202 ............never believed a 202 could go this well

G'day

I do a lot of high speed miles across country roads, so performance and economy are issues for me. Yes the big V8s went well, but front ends flogged out quickly and fuel costs were high when fuel was cheap.
For me the total cost of a V6 conversion just doesn't add up for little or no on road performance gains.

I used my old CFS 202 3 speed manual on gas to retrieve a CFL truck and a shed full of spares. I calculated the total  weight as:
CFS van with tools etc      1400kg
Car Trailer                         700kg
CFL truck with steel tray   2200kg
Filled van with parts          1000kg
Filled tray with more parts 1000kg

And I drove it over 60ks to get home. It was a slow trip, but I did it.

thats almost 7 ton!!!! far out!!

reminds me of the time i bought a CFL van i went borrowed a car trailer with my CFS got there and put the plates from the CFS onto the CFL.. put the CFS on the car trailer and loaded pretty much a van in parts into the back of both vans.. so would have been not too far off that hey.. lucky the CFL still had the Orig diff!!!

1400 for the CFS

1500 for the CFL

700 for the trailer

1000 for the parts..

thats almost 5 ton!! far out! no way cant belie it!

i remember one traffic lights.. they went green i put my foot on the gas.. we didnt even make it through the interecetion before the traffic lights had turned red again lol!!

now seems like a good time to ask.....

What,s involved in going from red to blue?
just sump and engine cover? or do the mounts need modifying???

[ben]

same mounts..

[BlackBedford]

G'day

The motors are basically the same especially below the head gasket, so the mounts do not need modifying.
To go from red to blue you need to change the sump and oil pickup if you get a motor from a Commodore. Blue motors were also in WB utes and vans.
plus...
The flywheel is different in a blue motor and the best solution is to use a red flywheel as clutch plates for blue motors are more expensive and harder to find when doing conversions.

The blue motor has a 12 port head that came in 2 types, one with air injection and one without. The one without air injectors is less prone to cracking. Some heads do not have the injectors but have plugs in the holes so watch out for that one.

The inlet manifold is larger on a blue motor and it is worth using it even if you have to make a bigger engine cover. Throw the Varijet carby and put on a Weber off a XE/XF Falcon for better performance and economy.

The outlet manifold is also larger and in 2 pieces but you would be much better to get a set of extractors.

While blue motors rev much better due to the counterbalanced crankshaft, they have a habit of throwing number 2 or 3 conrod out the side of the block. ARP rodbolts cure this and are are highly recommended.

There is also a black motor (VK Commodore) which is a blue motor with a few changes including optional EFI.

Identifying A red/blue/black motor can be an issue. There is a casting on the side of the block that is either 202 or 3.3. The 202 casting indicates a red motor, however some HZ red motors had 3.3 cast into them. Generally though 3.3 will indicate a blue/black motor.

You can fit a red head on a blue motor but there is a couple of holes to be drilled in the head or block to match them up, but the blue head is much better anyway.

There is lots more that can be said about the motors but this is a start.

Well I must say up front I was never a big fan of the 202 as I always thought they were a lazy, thirstyish motor, however was just over at the local speed shop (jeep broke!!) and got to talking about 202's, he said he had just finished one that had 235 rwh (300 @ flywheel) which when reving at 7 grand you could sit a glass of wine (posh drinker me thinks) on top as it was that smooth.
Those sorts of figures have surely opened my eyes to the potential of the good old 202.
Just glad I didn't have to finance it

G'day
The 202 can be made to go real hard.
I bought a 3.3 black EFI out of the Trading Post for $400, that had well over $7000 spent on it, and man does it have some go in it.
It was on the Mornington Peninsula in Vic, and cost me $200 to get it home, but was well worth it.

Note a Toyota Supercharger will fit on a 202 in a CF for even more fun.

202 blue has electronic ignition
neads 12V at the coil. so you will have to fit a relay

Hey photol,
               there's a bedofrd on here with an RB30 fitted already. Once you add a turbo, it's not really going to assist you with economy much! As it's function is to ram goodies down the throught of your engine. My mate has a Nissen Stegea wagon with a turbo RB25. The wagon rips but the economy is crap! But I'm sure it's most likely cheaper than my Chev! I'll have to do a run with him some day and do a $ for $ comparisin. Porr bloke paid twice as mush for his wagon than what I paid for the van and when ever I pull up next to him, no one even looks at the Stegea again.
