    Default cheap performance 202

    Hi all, My son is putting together a Holden EJ ute, he has a red HQ 202 engine that he wants to use, we also have a black 202. We were wanting to use the 12 port Black head crank and rods, I understand that using the black head means drilling some holes to accommodate cooling passages/holes. We also have 2 ford weber carbs, ADM34's. After some advice on anything concerning this combination and anything we can do to increase HP without spending a bundle of cash, any advice would be welcomed.... I also understand that this won't be a balls out engine but considering it is replacing a grey 138, i'd say its a performance option for the old ute...!!

    why not use the black 202 bottom end ? (as well as the black head)
    crank is better for starters... and no issue using the matching head


    use a mild cam (don't go silly) and the Weber34 is a match
    (lots ditch the Varajet when it dies and stick the Ford weber on)
    up the comp a bit... to help (take a fraction off the head)
    use the normal HEI XT5 ignition (NOT the later computer controlled ignition)
    .. dizzy and matching coil

    and finally go a decent set of stainless extractors but make sure they go with
    the Weber based inlet manifold (some do not and you end using spacers and stuff... )

    Gday Smitty, we are going to use the black crank and rods too mate {actually mention that above}, from what I've read the counterbalanced later cranks offer much smoother operation and more torque. I have 2 electronic dizzy's off blue 6's as well.
    Is it worth doing any port work, I know the 12 port heads flow better than the 9's stock but is it worth cleaning them up ? The head I have doesn't have the ports in the inlet side the carbed 12 ports do {air injection ? pollution stuff?} Never put together a holden 6 before, owned a few though.... From what I've read the black fuel injection 12 port already had a reasonable sized cam, similar to XU1 spec, smoothed out by the counter balanced crank, Any recommendations on a cam or extractors ? I've done a bit of searching but haven't come up with anything definitive yet... Thanks for your help...

    "up the comp a bit"

    Would flat top pistons be ok to help with this or just deck the head, I have to buy pistons for it anyway ?

    sorry mate... i took it you were going to use the red 202 (as you said you had one)
    but
    use as much black 12 port headed counterweighted crank black motor stuff as you can

    clean up the head, get rid of the casting dags missed in fettling in the casting plant
    and then port match it the manifold (leave the runners alone as they need a slight rough finish)

    I would suggest something along the lines of the cam in the first 186 XU1 engine, not really
    rad but enough lift and timing to wake the engine up a bit... as long as you had decent comp
    (if the pistons are down, deck the block otherwise a cut off the head to up to say 9.5 ish)

    extractors... you need ones that with go in the EJ with the black motor
    best were either LJ XUI 202 series II ones (like hens' teeth though and as they were mild, probably rusted)
    or.. if they fit into the body space, the Injected black motor ones which are stainless
    but
    whatever you get, make sure they fit with your inlet manifold, Lots don't and you end up filing/grinding
    bits off both manifolds to get 'em to fit

    Thanks for the reply Smitty. I have no practical experience with these engines, only know what I've been told and through what I've read, I do understand how it all works though, just thought there may be some tips and tricks that could help. Matching the manifold to the head is fairly straight forward, as is cleaning up the casting dags so I'll give that a go, I was recently given an air porting tool so I'll have to invest in some burrs for it. Wouldn't the XU1 headers be 9 port ? Any suggestion for pistons ?

    It looks like headers are going to be a pain in the arse, I have a mate that's made his own pipes for his big block Chev, getting something to "fit" may require some heat and gentle persuasion..

    Many years ago (91-92) after moving from my HJ sedan I bought a VH Commodore, 202 Blue motor, 4speed as my new ride. It even had A/C.

    I rebuilt the engine, balanced bottom end, flat top pistons, JP alloy timing gears, kept the standard HEI dizzy (regraphed) Crow Hydraulic Cam (pretty sure it was a 5665, might have been the smaller 5603 grind) fitted off the shelf Genie extractors, the 12 port head was reco’d, shaved a bit, ports cleaned up (by a mate that used to race speedway), good valve job, slightly bigger valves from memory (don’t quote me on that though), decent springs, wanted to fit roller rockers but couldn’t afford them. I initially added a Weber Carby off an XE or XF Falcon, but I ended up ditching it for a 350 Holley with some tweaks here and there from my speedway mate.
    It wasn’t anything fancy but it went really well for what it was. Fuel economy not so good....

    you will need the factory stainless steel extractors or aftermarket (XU1 no good)
    pstons... any hyper flat top. Surely Mahle or SRP or TRW or someone does 'em

    Thanks for chiming in Crab, the Holley's are thirsty, I had on on a LJ Torana in the early 80's, how much better was the holley to the weber performance wise?
    I'll probably stick with the weber for the time being as we already have it, just curious what the difference was...

    Thanks Smitty, I'll go look at the stainless extractors, so these were stock on injected VK's ? I've never actually seen them before, off to see Mr google...

    The Holley went better than the Weber, but that’s mainly as at the time my lack of knowledge (and many others back then) on getting the Weber right.

    Plus, the Holley was easy to play with and get parts etc. and my speedway mate could help me out.
    Realistically the Weber should be more than ample for a Holden 6 as they used to feed a 4.1 litre Engine.

    There's a mob not far from me that used to make conversion kits for the weber onto Holden, I'll have a talk to them, thanks for your help...
