    Yes it can, but the standard manifold is good for way more than the 230kw+ that you're after.

    ITBs aren't really for power, more response. You will gain dick all performance by wacking them on an N/A 6 that doesn't rev particularly high. For the cost of building the rest of the engine to make proper use of those ITBs you might as well just go FI and get more power.

    This was done on V6 Vengeance and I think it actually lost power.

    Do some maths & work out how much your motor could possibly pump at max revs and then start from there. Just understand that for every mm2 larger you make the TB's it *will* cost you something somewhere. Nothing is free.

    Really wouldn't bother with any kind of manifold mods uneducated people crap on about how good their twin throttles are but the reality is even I highly strung buick wouldn't 't max out a 65mm 5L throttle body think about it buick v6s have 6 small inlet valves which can only flow so much without FI it doesn't matter how big the inlet into the engine is the restriction is in the head.

    The problem hick inlet manifolds do have is air distribution between cylinders, ITBs would solve this problem but the gains are next to nothing powerwise v6 vengence lost power with the 3 smaller TB manifold but dropped around 3 tenths off the Et

    The only way you could get close to that sort of power would be to:


    • Stroke the engine to a 4.3L.
    • Throw in the most aggressive cam you can get and some Yella Terra standard ratio roller rockers.
    • Modify the heads (3 angle valve grind, larger valves).
    • Lighten the engine internals to reduce rotating mass.
    • Put on some clarko's pulleys.
    • Port match the intake and exhaust ports in the engine.
    • Upgrade fuel system to be able to run E85 fuel.
    • Then get a really good tune.

    Don't forget power is one thing, but if you want your car to go fast you'll need to strip it out. Anything that isn't needed remove it from the car, look at lightening anything on the car to reduce weight (carbon fiber parts, lexan windows ect), also look into reducing wind drag.

    All of the above would make your car fast, not really street legal or nice to drive & it would cost a lot to do.

    It just depends on how serious you are about wanting it?

    But is very possible to run quicker then the 12.8 inline6, alot of learnig an playing around but possible. Mine has gone 12.3@108mph with a nat. asperated 4.3l stroker v6 on Bp ultimate fuel an full weight Vn commodore( had the basics pulled out like jack an spare wheel but that was all for weight)

    ^^^ was also done with the original intake manifold design, but ported with a 70mm t/body an modded bend.
    but be ready for it to cost abit if your paying someone to do the engine an surronding bits to do it.

    It has been toyed with, however in the early days their wasn't a lot of support the the alloytec engines and coupled with a lack of tuning solutions it's not a cheap option.

    The other issue is that the alloytec is a lot wider than the earlier V6 engines so room in the bay is an issue.

    For $10k, you'd strap a big arsed turbo on @20psi and make 400rwkw. Juz sayin.

    cost us $2500nz including the $400 welder we built it with that includes the cam injectors map exhaust etc everything brandnew chinese wastegate chinese turbo chinese oil feed (lasted 2 years before it blew on the skid pad after the nylon liner got hot LOL).log manifold cost $50 for some steampipe T3 flange and an weld elbow, recycled vn header flange vp cast drivers manifold and vn y-pipe bends recycled for crossover LOL. before valvesprings it made 280rwkw at 5200 rpm on 14psi.it did 11.7@116mph both manual and auto after springs went 11.2 at 118 swapped turbo and upped boost 19psi 11.02@121 or so has had runs at 21psi but overpowers the tyres a bit and the torque convertor is flaring more and more as we add power.you punch the gas it flashes straight to 5000rpm+

    whole car as it sits including purchase of car t350 auto conversion and any mods weve done $5000 and so close to doing a 10.99 but we ran out of events LOL

    That must be a flash welder, my 2nd hand one was less then $200 and it was a decent little portable BOC unit. Welds good to for an amateur like me. It's only an ARC welder but I quiet like ARC.

    First off, that falcon is guaranteed to have an engine swap. Even the most ridiculously built SOHC N/A falcons only made around 175rwkw, so i dunno where you got that figure from. Secondly, why do you even what to out do him? What makes this guy so special to you?

    You need to rethink if you even want to be in this scene. If you were legitimate in wanting more power, you'd do it on your own terms and not trying to beat other people. TRY AND BEAT YOURSELF! Go to the strip and get a time, then beat that time. Again and again and again. Eventually you'll get a trap that you'll be happy with, and you'll feel proud at what you've accomplished for YOURSELF and not trying to prove god knows what to a random dude in a Falcon.

    Chances are you'll run a 15.5+, and that's pretty standard for a commodore of this age. If you can shave a good 1.5 seconds off that speed for yourself then I'd be MUCH more impressed than what you're proposing. Might even give you a pat on the bum.

    I don't think this has had an engine swap. The figure is plastered all over the ford forums, look up:
    BROCKYB8 Gmtezr - With a number plate like that, I'm surprised more mad Holden fans aren't trying to beat him.

    This is the car in question.
