red/blue 202's

[4PLAYN]

Can red and blue 202's be interchangable bettween HQ and VH?

At the moment there is a red 202 in my HQ GTS look alike and i wouldnt mind giving it all new bearings and gaskets and seals + making it a bit more powerful in the process.

Would it be a direct bolt in fit so i dont have to pull the car off the ropad for a month or two during rebuild?

The red 202 in the HQ has a 3 speed column shift in it
The blue 202 in the VH has a 3 speed automatic.

If its a bolt in direct fit i will be happy as all hell.

Cheers

The red 202 is a pre pollution motor and it would be illegal to put it in your VH as the HQ doesn't have the same emmision control as the VH does.

Slim I think he wants to drop the blue 202 into the HQ (do ya mate?).. engine should use the same mounting points but I'm not sure about the tranny, think you might need an adapter plate but I have NFI, sorry

[craigvk]

I am sure the HQ transmission will bolt up fine and the motor should drop in as the mounts are the same I think. Just bits of the motor are different.

Whats the difference between the blue 202 and the red one? what pollution gear is there? How hard is it to hook up ??

[craigvk]

I think the manifolds are different and also the carby. Someone else could give further info.

Manifolds are different. Red manifolds will not fit blue motors. Red motor has single barrel stromberg carb Blue motor has two barrel Varajet carb. Red motor exhaust manifold has single outlet,earlier red manifolds exit on a different angle to the later ones. HX and later were different. Blue motor exhaust manifold has two outlet pipes. Engine mounts and bellhousing will bolt straight up.Blue motor electronic dizzy will fit Red motor. Blue motor uses bigger diameter clutch and flywheel. Dont know if starter motors are interchangeable. Spigot bush is different from auto to manual, so they will have to be swapped

starter motors are the same

[4PLAYN]

hmmm maybe i should just look for another VB-VC-VH-VK in adelaide and work on that .... and just use the vh for a put around car till the new one is finished enginewise.

The oil sumps are different on the 202 between the kingswoods and commodores.

The deepest part of the sump on the kingswood is at the back of the motor, and at the front of the motor on commodores.

The steering rack will get in the way of the sump either way you go if you don't change the sump over.

[4PLAYN]

Between the blue and red engines can you swap parts over so you have an engine like this ....

red block, blue sump, blue head and manifolds with the correct carby.

But then will it still connect to the auto without changine the crank over?

will red motor extractors fit blue motor as i have a set of red 202 extractors i would to put on my vh blue 202
vh commodore

[craigvk]

I am pretty sure they won't. I am sure the blue motor has a 9 port head and the red has a 12 port head.

thanks alot saves time tryin to fit lookin for blue motor ones

[DANNY8]

Yeah red motor extractors fit on blue motors. I chucked a set of extractors from a red 202 onto my blue 173.

On the red motors, it's just the intake ports which are different. The exhaust ports are basically the same, possibly smaller tho. But I put red motor extractors on my blue 173 and I could still notice a good improvement. The only problem I had was that the last pipe had to be levered over a fraction so the bolt would fit in, and a small bit needs to be grinded away on the face of the tubes (the bits which make contact with the head) so the intake fits over...only about 2 need to have a few mm's grinded away.

But it might be better finding a set of blue motor extractors, a lot less stuffing around haha. Also black motor extractors will fit, but the extractors from the EFI 202 don't fit.

thanks im thinkin i might just get a set off a blue motor to be sure

Blue sump will fit red motor no prblems but you must change the oil pickup tube as well to suit the sump. Blue head can be fitted to Red motor if you drill extra water passage holes in the Red block and use a Blue motor head gasket. Blue motor flex plate and auto should bolt up OK
