Once tuning comes out for the L61, I know that quite a few guys will be going f/i. On behalf of those of us who are going to wait a little longer before we dig that deep into our pockets, I have a quick question: How much of a power gain are we looking at by tuning the 2.2 while staying n/a? I know that realistically, the results of tuning the 2.2 won't be earth-shattering, but I was just curious. So, what do you guys think?

 

depends on mods.

 

I/H/E, injectors.. with Tuning...

270 WHP
229 lbs/ft tq..

...at the minimum.

 

^^^^^ sounds close... maybe throw some nitrous and try rocking with ss/sc.. with all those mods stated in the above statement

 

Lets say a fully bolted 2.2.


*cough* Theres always one in every crowd.

But seriously, how much more power is available for us guys that will be n/a for a while? I know it is hard to say because no one has done it yet, but someone must have a pretty good idea about it.

 

Normally Aspirated. You will not get that normally aspirated. Unless you blow a pant load of nitrous at it.

 

B I N G O ! ! ! !

 

I said B4 not C4 ugh no BINGO yet everyone keep playing

 

i think he was trying to be sarcastic

 

you sirry american!! reary?! lol god damn mongolians

 

Sooo... anyone have gut feeling about how much more power can be extracted through a custom tune? BTW I know that peak power isn't the only thing that could benefit, but for the sake of discussion I wanted to start with that.

 

With nothing but bolt-ons and a tune, you could make 165 realistically.

 

That sounds closer to reality, you can only do so much with out nos or f/i OR like i asked in another thread, can some one make a 2.2 or 2.4 or 2.0 a "stroker" and what is the bennifit of that??

 

We have investigated this in the past. The LSJ and L61 engines are the most compatible, but the crank reluctor ring trigger is an issue.

For these engines, the benefits versus cost simply doesn't make sense.

 

That makes sence.

 

im planning on running a 75 shotwet kit...... i expect to run 13.7-13.9 hp wise id say over 200whp...

there is a local guy who pwnds stg 2 cobalts.. buy 3- 4 cars...... with the same kit

 

How does Over 200 beat at least 260 from a S2 SS/SC?

 

idk... i saw it happen with my own 2 eyes.... he is auto so he can spray all the way though the gears... the thing halled ass... he hasnt dynoed yet so hp wise idk what he has... i do know it has to be over 2oo/220

 

Some one on here was trying to dyno an auto and couldnt get it to stay in 3rd or something like that so good luck to your friend.

 

Traction.

Thats how he won.

Lauch with little horsepower than start spraying. S/CS2 no traction.

 

yep.... at 45 when he sprays.. nd it shifts down to his passing gear he lights them up nd all u see is smoke from his tires its baller.. he has beaten an ass load of cars...... that he shouldnt........

 

So in other words, tuning could be as beneficial as all the bolt-ons? I would be very happy for the time being with numbers like that.

 

I know Im getting on this a bit late and Im probably gonna get flamed to crap for this but, a friend of mine with a civic running a 2L n/a puts down 250whp. Mind you this motor is Piston/Rods/Cams/Valves/Springs/Porting/Ballanced.... Basically all but sleves. Tuned with hondata.

Id guess that for one of us to put down simiar #'s in an n/a 2.2, similar modifications would also have to be done. Running an oe bottom end with a well built head/cams/valvetrain (Higher compression?) & feul system 200 dosent seem unreasonable. On a tune of course.

Are there any resident engine pros that would agree or disagree with this?

 

I don't think you'd reach those power levels on a stock bottom end. Those Honda guys run crazy high compression with those N/A builds. That mixed with a lotta RPM's is what makes them power but the motors are so peaky with that. All top end...

For a strong N/A build I think you'd have to be running atleast 11:1 compression to pass 200whp

 

Pardon me for being a bit on the "old school" but can you not acomplish an 11:1 or close to it by shaving the head?
