I came across the "performance modifications" thread, and between that, and every "built" LE5 I've seen in someone's signature, it seems that to make more power out of the LE5 that you need either a supercharger setup, a turbocharger setup, or nitrous...

Have I missed something?

Sure boost or nitrous is an easy way to make power, but can you guys not make any significant power increases while keeping the motor's naturally aspirated (w/o nitrous)??

Can't you bump compression, swap cams, get a header, and tune the crap outta the 2.4??

thanks in advance for cluing me in...

 

It'd be retardted to dump 3-4 k to get 250 whp that's what everyone Has realized

 

you can do just about anything if you have the money.
boost/N2O is significantly cheaper (and more streetable) if your looking for 200+ whp

 

Boost is a hell of a lot cheaper for these cars.

 

i think what he is getting at is why cant we build up to about 250ish whp like some honda engines

the answer is simple... its not that we cant, its that our aftermarket is not a large, making parts much more expensive

that being said, for the money to build the engine, u can go turbo and make much higher numbers for a similar price

 

but no one has tried to see what an NA LE5 can make - just for kicks?

or to be different?

 

i beleive theres a guy on here that makes over 200whp naturally aspirated, dont know what his name is on here, but he put a lot of money into it.

 

On a 4 cyl, boost/juice is where the cheap power is. You could spend a fuckton on an N/A build and still have issues cracking 220WHP. For the same price as building a 200+ WHP N/A car, you could've had a 300WHP+ boosted car.

N/A builds are easier done on large displacement V8 engines... not 2.2L/2.4L 4 bangers. GM did have the 190HP LG0 Quad 4, but GM found it easier and more worthwhile to just use boost.

 

again the former Quad4 guy here nailed exactly why I was thinking this;

quantity is irrelevant - the LE5 IS supported by the aftermarket at this time...

With the Quad4 it isn't rocket science to break 200whp, but most Quad4 owners happen to be poor kids who have a Quad4 because that's all they could afford...

But most aren't me...

I was going to write more on the subject, but I don't want to bore you guys;
I am actually surprised that there seems to be so little interest in n/a builds since at this time the aftermarket does support your engines...

I think there's some thing to be said about a nice NA build - I mean the Civic SI now even comes with a 190hp n/a/ engine - I would think that anything which can be done by the honda could be matched by the LE5!?




Ok... please humor this last bit (a tangent at that) here;

If anyone here may have been a Jbody guy in the past, and has any leads on a Torsen LSD (which used to be sold for the Quad4 cars (through GM/Oldsmobile)) please PM me!!!
(I have been looking for over a year already.)

 

civic Si's can be beaten by bolt on 2.2s....

 

really?

wow, they must have horrible gears, or a wicked high friction drivetrain!?

no offense to the 2.2L guys, but I'd think although possible, that alot would need to be done to make up for the 50hp disparity.

 

My buddies 2.4 bolt on Cobalt destoried two RSXs. Honda's are that fast?

 

I put the 2.2L & 2.4L in kinda differnt catagories;

the 2.2L has a 50hp disparity to the newest Civic SI engine;

the 2.4L has a 20hp disparity to the newest Civic SI engine.

Please note, I am not talking the bread & butter engines, (I'm not honda guy btw) I've understood the SI motor couldn't be had in any other Honda car - and the 190hp engine was the whole basis for the SI package.

 

2.2 and 2.4 both will full bolt on's are pretty much dead even.

 

exactly...Thats why im not touching the engine...i have a 07 thats in perfect condition, with only 25k on the speedo...blue book says 8grand...now dump another 2-3k on mods? no thanks i will sell it and buy something better...

yes sir.

 

I don't want to get into exact numbers because I hate Hondas and I know someone will try and bash me for saying something but. There may be that power disparity in bhp from the magazines and what GM claims and Honda claims. What I am saying is, the gap of horsepower is probably smaller than what you may think because of WHP. And don't forget Honda's have AWFUL torque curves and you pretty much don't get any horsepower either until you hit VTEC. So from 1k RPM to 4k you are just sitting there. And the other argument that can be made is horsepower to weight ratio, and gearing. That is why the stock 2.4 is almost dead even with an Si. Personally I was dead ass even completely stock with a completely stock Si when I first got my car. Now I'm only a little faster. But from 0mph its all Cobalt 2.4L.


I also thought this was kinda funny. Click this link and scroll down to the Torque part. But also don't forget to look at horsepower. 197@7800. 7800RPM, way too high, way too long.

Most be nice to have good flowing large port heads from factory....

 

yall say we are supposrted in the aftermarket world? yes we have a lot of headers, intakes, and cat back to choose from but look at cams for instance. for the 2.4 we have JBP tri flow cams and that's it. half the people that ordered them never even got them. so we can basically say that we don't have an aftermarket cam for our cars unless you do custom regrinded cams which would be costly and you really have to know exactly what it is your doing.

i personally plan on doing full bolt ons and PnP my TB, or just going LSJ TB. and after that i guess wait for cams or something. my car is too new to change compression by shaving heads or whatever else. i got 30k miles on it.

A good port job to match the stock cams and some high compression pistons would suite the community well.

 

u talking about PnP the heads? thats pretty damn expensive isn't it?

 

can someone clarify something for me?

what exactly is meant by "bolt ons"?

 

Depends. If you know what you're doing, you can do it yourself. I know shops around here charging like $150 if you give them a barehead with flow benching.

On a 2.4, I/H/DP/E/T

On a 2.2, I/H/DP/E/IM/TB/T

 

umm, since I didn't know what was meant by "bolt ons", why would I understand single character abbreviations?

Can you please spell those out for me?

all that I can guess for bolt ons would be a CAI, and a header...

 

uhh not quite... 2.2's dont respond to bolt ons any better then the 2.4's. Both gain just as much which makes them still the same distance apart in performance when fully bolted.

2.2's catch up when you start putting the 2.4 TB's and intake manifolds on them as well. But ive done a highway run against a 2.2 with intake, full exhuast and a tune and i beat him by half a car and i was bone stock.

If you go to the dyno thread as well, you can see a 2.2 with the basic bolt ons, intake, header, DP, catback and a tune, makes in the 150 range, thats what a stock 2.4 puts down. A 2.4 with those same mods, puts down in the high 170 range

 

Intake manifold and throttle body are bolt on's FYI.
