Forced Induction Who Wins? XRS vrs 6psi boosted 01?

Hey this thread is great!
But is common sense, you have to look at the torque, a turbocharged 1zz-fe puts out more torque than a 2zz-ge. So a 1/4 mile run, the turbocharge corolla would win easy.

ill keep it short and simple....

turboed 1zzfe @ 6psi will win a xrs corolla.

i have like 2800 can i get a turbo with that much lol i want one NO

with lift bolts breaking all over...

or does there new lift bolt fix that the TSB was issued on?

That was fixed way back in 2002 or something like that on the Celica GTS, never an issue on the Matrix or Corolla XRS.

Bulletproofswordsman, that's enough if you want to bring your up to me and leave it here for a bit.

i know it was the gts and a tsb was put out but i still see peopel complaining about it on the celica forums... i guess they never got theirs replaced...

its a good engine though!

Also If Dr Tweak will do this setup for you for $2800.00 Try not to get a ticket but go and go fast.... its a VERY VERY good price.. I spent more then that on mine I think but then again I spent orver $200.00 just oil the oil and water earls type fittings and stainless steel hose etc.... although maybe i spent less then 2800... but still for him to do it all and not learn to weld or have a shop charge you (i got quoted 4.5K - 10K)....

and with his rep id trust tweak with my car even though ive never seen him... i saw his work... he takes a little while but its cheap and quality... a rare find!

damnit tweak. ur in vermont......i wud so do it if i wasnt a gillion miles away, damn shops around here wanna rape you with prices

You cant really compare cars just by saying it runs x amount of boost.

A properly tuned car running say 6 psi, will eat up a poorly tuned car of higher boost. You also have to look at gearing and everything... it's not hp numbers that win races. I'm boosted so im not taking sides when I say this... an XRS is a mid-15 second car stock. All custom turbo setups will perform differently so its too general to say one will be quicker than the other on paper, there are millions of variables. Some of you all gave the same type of comments about the 1zz as Faisal did about his 2zz... then you all give him crap about it.

just my .02

Are you turbo or super charger?

Esentially HP does win races! A 300 hp car vs a 200 HP car at the same weight should win.... The 300 hp car would lose only if it had insane problems with getting the power to the ground.

HP wins the race bad tranny or getting it to the gorund may lose it though... however when the difference is a LOT of horsepower the higher hp car in the quarter mile should win unless soemthing is seriously ewrong... around turns autocrossing etc is different but in a straight run.....

Also the gearing for the corolla vs the xrs isnt that different excpet the 6spd in the xrs may cause 1 extra shift on the track which could slow him down.... or the smaller gear ratio can help him BUT that will only help if the weight and hp numbers are close... otherwise it wont help much....

Also of course a properly tuned car will run better faster etc... and if the turbo was set up correctly then the turbod car will win.... the only way i could see a turbo not winning is a huge dump truck turbo on the car... (if the turbo car has significantly more power)

first you say HP does win races, then you say it should win races... It all comes down to how well you use the power you have.

I'm mearly stating that it's not "turbo will win, case closed". Most people that boast about turbo's being gods gift to the road have never owned or driven a turbocharged car. They just jump on the Fast&Furious bandwagon.


If you want my opinion to the question... 6 lbs of boost is a pretty low boost setting. The 01' pushes what... 120ish stock? a 6 psi setup will put you at maybe 170, if you are lucky. The same as an XRS... so if you want to play the hp game then it is a tie right? Well, over 4 years there have been upgrades to the 1zz and 2zz. Better fuel delivery, more aggressive fuel curves, a 6-speed tranny and sport suspension to name a few, remember... the XRS is tecnically a sport edition Corolla. Sorry, but your 6 psi 01' will be staring at taillights...


...and for the record torque wins races.

hp is a function of torque so hp torgque is about the same...

second i said essentially hp wins unless something else is wrong high hp will win (which usually means high torque as well) if your drivetrain sucks or you have a bad clutch then itll turn possibly

third i posted my Dyno at 7 psi a 00 corolla making 221 hp... your saying at 6psi ill have 170... damn so if i run 8 psi your saying I will have 270 hp??? look at the dyno on page 2! (not trying to be an ass if thats how it comes off as just check the dyno as im assuming you skipped it) also the turbo car has over 70 more wheel toque then the 2zz.... so by your argument the turbo 1zz wins... (more torque) also the 01 has about 106 whp stock..

And about how you use the power is what I was also tryign to say.. if you cant drive or your drivetrain is crap youll lose but if otherwise that is equal then the higher hp higher torque and lower weight car should win.

Im really not trying to come off as an ass im just trying to give the facts that a turboed 1zz should win unless you have a shitty setup... cant drive worth shit.... or have a dying clutch.... i make this assumption based upon my dyno of my turboed 1zz and celica gt's dynos and mrs dyno's or turboed 1zz's

HP = Torque x RPM/5250, Horsepower is a arbitrary unit to show how torque work over the RPM band.

no way your at 14 with stock internals??

I'm driving up in a couple of weeks -- want to tag along?

dangit say 10 psi then lol you always get me with that

Don't forget too that a major factor is *where* the engine is making the power. For example, if two cars of equal weight and driving skill were put against each other, and one has say, 200hp and the other has say, 350hp, the 200hp car could easily beat it. How? *If* the 350hp car made only 350hp at say, 6500 rpm (with a 7500 rpm redline) but it only makes 150 hp until 6500 rpm (when the turbo spools), but the 200hp car makes a flat 200 hp from say, 5000 rpm all the way to 7500 rpm, then the 200hp car will completely destroy the 350hp car, get it?

By the same token, a very high revving n/a engine (like the 2ZZ, which makes most of it's power AFTER 6700 rpm) is very peaky with a very narrow powerband. On the other hand, a midrange sized turbo system will make a very flat power and torque curve right from the point that turbo reaches full boost (hopefully no higher than 4000 rpm). So the turbo car could make potentially less power with a WIDER powerband, and still beat the higher hp 2ZZGE.

Wow this thread is going nuts I need to turbo my car damn it!

ok yeah your right i was assuming a rather normal engien that isnt liek the 2zz that has the cam or whatrever switch....

most cars power band with the turbo added stay close to the same if the correct turbo is put on... ie corolla start to pull around 3500 rpms or so maybe 4K rpm when NA and mmy turbo spools at 3000 but starts to pull and reach full spool at 3500...

thats why i said up above if you put a huge turbo and dont spool til really late your not using that power.... but how often do you find a car liek that.... 150 to 6500 rpm and 350 after.... that wouldnt be possible I think.... but that case does prove where it wouldnt work... however show me an engine that does that.... (a turboed 2zz doesnt do that dramatic an increase)

oh well this is pointless because there are tons of situations that can be exceptions... im just going more with general case.... most points people brought up are completely valid other then a 2zz xrs killing a turbod 1zz at 6psi

a man who knows wtf hes talkin about/\ give it up for tweak, yall

In general you won't see that situation, but that's exactly the result if you used a turbo that was too large for the application. It would make great power way up top but no midrange. That was just a more extreme example of the way the 2ZZ makes power though, which is just like that: a very narrow, peaky band of power at the very top of the range.

yeah the 2zz is a nice high revving engine but I sometimes wonder how well it would compare to say 160 whp to 6500 rpm linear climb vs say a 180who gts that spikes at 6700 rpm but when you shift you start a lot lower then lift I would imagine...

And yeah I guess I might not have mentioned a turbo that is too large wont spool upo until too late to gbe useful... however if you can increase redlien etc you can then use the power....

Really you have to look at turbo flow maps and check how well they work with your car... i looked at a bunch of them and decided on the t3 super 60 .48/.60..... a .42/.48 would work as well but would spool up faster and have lower top end which I wanted a better top end.... I would have prefered different turbos like the gt series but I couldnt afford it... and still cant

if your getting a custom turbo set up plan what your goal is and then aim the turbo at that goal... unless your goal is 500 hp dont buy a 500 hp turbo yet LoL..

Oh well this just proves there are exceptions and a turbo isnt god sent.... although im a large fan of turbos vs superchargers just because of the bad supercharger results on the 1zz engines that I have seen...

I feel like the XRS question was ansered... do most peopel agree that a corectly turboed 1zz with the right size turbo at 6 psi win.... Id say yes of course

I wont chime in anymore unless I need to though I dont want to keep this ongoing LoL... but a lot of useful information was posted above...
