    Turbo ecomoo

    May have an opportunity to tinker shortly. Not quite 13s/$1300 style but budget-ish.

    I know the L67/supercharged bottom end is better but that's not happening. So what do people know about the strength of normal ecomoos? I hesitate to put any weight on information from Commodore forums.

    Is 350rwhp unrealistic from an unopened motor (+arp head studs) on 98 (+maybe cam/rockers)? I hear all these stories of blown head gaskets, legs out, melted pistons... how much of that is true and how much is due to... er... Commodore owners?

    Spend all money on turbo system, maximum boost, thrash, blow up, sped $50 and half a weekend swapping in fresh Ecotec, rinse & repeat.

    Alternatively pour money into strengthening Ecotec only to make less power than a stock LS and 6000rpm of boosted disappointment when you lunch it anyway.
    They're pretty hardy motors for what they are, I'd go as far as a basic tear down of sump, gasket, head gaskets/studs and a general removal of buildup/gunk. Roller rockers etc..... if you're committed as they can be swapped over to a fresh motor. I wouldn't bother with anything cam/bottom end related as the probability of destruction is high.

    Keep you're longevity expectations low and you'll never be disappointed.

    No interest in feeding it motors. What's the inherent weakness / reliable hp point?

    Run on e85 for extra powers. Make the car light as possible to make the low power faster.

    Are these seriously the opinions people are giving?

    Compact $0 engine of nearly four litres turbocharged a bad idea?

    When I was looking for a 1300s moo mang, I came across a lot of blown head gasket ecotecs. Between that and something else weak that I cant remember, it was enough to encorage me to spend extra n go buick. Yes extra. They fuckin cost more now than the eco...

    If you are wanting to do this as a low budget thrasher, you are probs only looking at 6 or 7 hundred more, initial outlay for a vt LS1 commo. If you look long enough. Then you are already way ahead on power and strength and will prob come across aftermarket shit cheaper.

    no the advice is fuck yes doit, but expect the engine to be swapped as per 5000ks service intervals.

    They do headgaskets, manifold gaskets and rod bearings combined with the fact a lot of them are pretty fucked to begin with and yeah, your going to be changing them out often if your going to beat on them.
    Spend the extra up front and buy one that wasnt ripped from a shitbox with 300k with only the odd service and you will have far better results, commwreck here sell legit good ones but they are not $50 and a 3 longnecks to buy.

    The problem with them is they were just never designed for boost/big power.
    Melt pistons, blow head gaskets, annihilate crank bearings etc.....
    They just can't handle big power.
    They're a moderate capacity moderate weight motor used to power a large and heavy family car, they're already working fairly hard.
    L67's had a a different block with modified oil galleries, stronger pistons and lower comp. etc....., which is why they'd handle boost better.
    If you really want to build a reliable 350hp boosted Ecomoo expect to fork out what you could have spend on an LS1 swap/commodore.

    Other than that, I think 300rwhp on a well serviced/sealed/cleaned moo is quit achievable and fairly reliable.
    Anything more than that (350+) and you really need to consider L67 or fork out $$$

    Is there a specific reason for turbo moo? An existing car with sentimental value?

    Otherwise, and yes, I'm gona be another guy that's gonna shove LS1 down your throats, get a cheap gen 3?
    There's are bargains to be had. I just picked up this a couple of weeks ago for $3500



    190,000km LS1, pacemakers, likely exhaust, receipts for 3k worth of pedders suspension underneath, 15x7's, working aircon and stereo.
    It's not te prettiest car, but it's tidy, basic and tough as nails.
    Absolute bucket of fun for the $ I've spent.
    Theres no reason that with some elbow grease myself I can tune/diff gear and/or 100hp nitrous shot and see myself into the mid-high 12's for under 5k

    Food for thought anyway.

    Most of the blown head gaskets can be fixed by replacing the intake gaskets…

    Melting pistons and shit means your tune is fucked up. I think if you actually try you could make a stock motor live. Most people boost them for lols and they break from lack of fucks. Stock head gaskets might be a good fuse to get the tune right without breaking bigger shit.

    Been thinking a xr6 turb would be a good size

    also, you will be looking at aftermarket ECU or delving into the crazy world of delco hacking?

    I didn't want to get all off track but short version is I'm considering buying some type of early 00's rwd dual cab ute that would otherwise be worth money, but has a blown engine. They come up all the time. Eg rodeos with alloytec.

    I have three ecotecs varying from really good to one that runs but is a parts motor.

    Instead of fixing existing engine, fit ecomoo and while it's all apart do basic log/crossover setup slightly less dodgy than 13s for 1300.

    And yes you can fit older engines in newer cars.

    So anyway if that makes more sense, carry on.

    If you want it to do daily duties and be cheap, ecotec is a perfect replacement rather than throwing good money after bad on an alloytec.

    As soon as you want to pep it up and have some fun, you are wasting money and keeping the car off the road. Bite the bullet and go ellis juan

    I used to be anti-turbo moo, but after doing a ton of fab work on them for a shop in Melbourne that specialises in them, they're actually a pretty damn good thing for not a lot of money.
    I wouldn't build a forged one, but a stocker with a few tweaks can take a surprising amount and spit out some good numbers.

    See that's where I'm at.

    They're lowish comp, big motor low revs I reckon with a manual and a high ute diff ratio like 4.11s even 250rwhp would be heaps.

    That's say 330hp at the engine they're 200hp stock, it didn't feel like much of a stretch to me.

    Hard to get valid info because people either hate them or reckon it's a fucking fantastic idea. I've had a basic 5sp/moo/4.11s/lsd rwd hilux before and it was awesome. Something dual cab so a little heavier, but with another 100-150 rwhp would be a little fun and (I imagined) pretty reliable.

    Stop. Stop creating delirium for yourself. You already have a perfectly good platform. It is about 100x better than a lump of force moo.

    Just dont man please! Use you smarts here and your gut. This is a pretty bad idea. I dont speak up much but this is one od those times.

    This makes sense.
    I still think 350 would be a risk but always worth a go.
    Replace the coils with new ones. Once one starts to loose power you'll know about it.......

    I think I just going thru and cleaning oil galleries and making sure the ignition/timing/tune side is good.
    CAS, harmonic balancer, coils etc.....

    The problem is you didn't want answers from commodore forums yet those same people are on pf giving you the same stupid answers. Saying they melt pistons and blow head gaskets and spin bearings and this is the engines fault, yet they can sit on the limiter for days having not had an oil change for 50,000 klms and not blow up with the factory tune in them.
