Mmm , no I don't think LS engines are what you'd call MATEE or more awesome than everyone else . The punch is mainly in the capacity and for its capacity aluminimum makes the block and heads relatively light . Some credit has to go to its EFI and ignition systems because these add a lot of refinement to any engine .

The thing is that for a six litre engine they are hardly the bees knees and I think locally this is because Commode Door drive lines and body shells aren't the same as some USDM cars .

There was actually an engine option in the US that the Yanks couldn't stomach and it had double over head cam lids on each bank . From memory Lotus did the heads but not sure ATM . Anyhow it revved and made good power but the Americans avoided them because it didn't spin the wheels at starter motor revs .

Anyway I call LS engine Ford 9 Inch diff syndrome , not high tech or good quality materials - just big and lots of .

IMO the REAL issue is that most manufacturers slap together a big heavy car to throw a V8 at and then you suffer the mid size "performance truck" issues . If they hook up they go in a straight line but fail dismally one you encounter bends and twists . The big lurid slides/drift wank business is anything but fast though it does impress the tyre screech and smoke kiddys .

Most people I know wouldn't call a Commodore agile or want to push them hard around twisty windy roads . Too big too heavy and don't want to stop or change direction because of it .

Multiu cam multi valve heads are about lots of valve/breathing area into compact efficient combustion chambers . You cannot replicate with two valves what you can do with four and buckets/push rods/rockers do not constitute a high performance valve train in my book . Show me a current F1 engine with pushrods or two valves per cylinder or big open chambers .

Sorry , I don't want one .

Yeah but end of the day they out perform an RB in everyway, sure it isn't as impressive from an engineering standpoint due to it being pushrod and 6 (thats a f**kload) litres. However it weighs less, makes more torque, power, and also more average power.

How can you not want one?

Exactly, its efficiency in terms of the amount of performance you get out of ahunk of metal which has can be made to fit in a lot of places fairly easily and weighs less than many things with the same or less performance.

man this thread has more twists and turns than Nurburg . I wonder if OP is even reading it anymore ?

But I think the big question arising here is power on a budget vs performance on a budget cause they are 2 difeerent ball games really..While an LS as an engine will make good solid power effortlessly everywhere fairly cheaply, making a car that can harness the power is costly in terms of tyre wear brakes etc etc.To the point that it will be quite easily outperformed on track by something as little as a honda that was built for half the price and will last twice as long.. Actually for a budget NA performerance engine something of the vtec variety would probably be my choice..the Lotus with the K20a look like so much fun..

K20A Civics are completely insane, and a lot cheaper base than a Lotus haha.

One of the first US time attacks (EVOs, GTRs etc included) was dominated by an EG Civic with a fairly mild K20A in it :) Even a EuroR H22A in a Civic actually, they aren't far off K20As but with more torque and way cheaper... I've actually been pondering building myself something along those lines for quite some time.

This.

Last night I thought about the combination of my said LS1 and my said R154 in the S14...

I then realised its a 1200ish kg car and a stock LS1 will be pretty average, while a good LS1 will be way too much. I then pondered further and realised power is one thing, but delivery is KING. The poor little SR still has a place in that car, I will push it to 240ish rwkw and have something that has power everywhere you need it, no power where you dont want it, and about as much power as I could realistically put to the ground (in more senses than traction, very much application specific).

As cool as it would be, I'm with Disco in saying, no thank you.

hardly budget mate, lotus..

I think the two comments are sepparate from eachother. Building an EG civic to dominate a track with a B series motor costs next to nothing. Have been there, have done that, it was faster than my modified R32 in a straight line and obliterated it around a track.

dont hear much about hondas big little victories these days though, most of their cars are too heavy now and everyone else is running turbos in bigger badder cars.. Im starting to wonder, is there a whole new scene out there I havent caught up with yet...or is the track day scene dying off somewhat with a new generation more concerned with luxuries and electronic gizmos than outright performance..I mean if I want a car to perform fisrt thing I do is rip out the airconditioning knowing i'm also helping the planet in the process... Which brings up another point, is it the threat we are destroying the planet curbing peoples enthusiasm towards the scene..

i see alot of mazda 3s kicking around and they look somewhat sporting but I dont really hear of any track weapons based on them, same goes for the MPS..although hondas new CRZ looks like it could be interesting. Maybe all the cool cars are coming out of europe now but I havent paid enough attention to know what they are. i dont know, but do you ever feel like theres a party somewhere and you werent invited,

Hmm gearbox just started to crunch going into 5th unless i do it really slow, might need to hold off on the overnight parts from japan until I know if im up for a new box or not.

Thoughts? Gonna try an oil change with that redline fluid and see if it helps, how much is an rb25 box anyway?

Crunching is just syncros, doesn't mean it will blow up, just that it is annoying to change. Outright torque and brutal gear changes are what kills boxes, so don't go slapping gears and you should be fine at stock power levels.

I've gotten well over a year out of my 20 box with a 240kw rb25 behind it.

haha, big bottles no throttle!!! :D

No2 is used by those that cant make power any other way hehe

dam multiquote won't work, had to post this one to make sense

same can be said for capacity,5.7-6.0-6.2 LS motors are old tech, i have had the chance to drive all these engines and i don't know what you guys are talkingabout they make no where near the power down low my R32 GTR does and it makes alot more torque with very few modds and does it in a much bigger band, getting usable boost at 2000rpm and full boost at 2700rpm through to the 8000rpm redline with peak torque at 3900 and peak power at 6500. thats a power band of about 5500rpm

you want cheap easy power, enough to see clear of a V8 SS for $1000 then a zex NO2 kit a good dump pipe and front pipe would be hard to beat and if you can find then second hand you could do it for less then the $1000

So much fight here with Skylines vs Rotorarys vs V8 commodores...

So I shall bring in a new contender; the Falcon XR6T (& F6), over the years it have grown to be quiet a formidable opponent against the V8 commodores in traffic light grand prix & up until recently with FPV releasing its SC V8, the F6 was the faster car in Ford's line up, beating the old Ford V8.

What's everybody's option of it? I'm thinking of buying one (older F6 or a current gen XR6T) as my next car & do the usual mods to it (most say you can get 300rwkw fairly easily with just bolt ons & flash tune).

On one of my trips to Albany I was following behind a XR6T and that thing just goes, everytime he pulls out to overtake some snail in Camrys/caravan/road train.

Yehhh they are ok. Similar story to the V8 Commodores though, their engines make bags of power/torque and yet they have to cart this heavy shell of a car around. My mate has an F6 Typhoon making 380rwhp, best he has managed to run at the drags is a 13.6. Given he isn't a pro drag racer, but he isn't the worst driver in the world either. He could maybe see a 13-flat if he got everything perfect, but he hasn't managed yet.

    • For once a good news  It needed to be adjusted by that one nut and it is ok  At least something was easy But thank you very much for help. But a small issue is now(gearbox) that when the car is stationary you can hear "clinking" from gearbox so some of the bearing is 100% not that happy... It goes away once you push clutch so it is 100% gearbox. Just if you know...what that bearing could be? It sounding like "spun bearing" but it is louder.
    • Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve. 
    • I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.
    • No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.
    • God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
