More grunt would be nice!

I have a 3.0L V6, it is nice, but lacks the low down torque of a bigger six.

Has anyone have any reasonable ideas on how to extract as much power as possible from this engine without things like SC or Port and Polish etc.

What is a good exhaust size/combination to maximise power and comfort? what do other people have? I am looking for a nice note without the drone or too much cabin noise.

Do K&N panel filters really improve power?

Advice on a CAI setup that keeps the MAF etc?

Thanks...

2.5" freeflow piping, custom y-pipe, custom headers or jpheaders, and custom cai

and what would you use instead of a maf?

some safc tuning could help een out the powerband as well


and for low-end torque, you just have to learn to drive your car better and stay in the powerband, really......but for maximum speed from a standstill, only a 5spd swap or a high stall torque converter will give real time gains

Sweet, thanks man.

I'll look into the exhaust side of things first. Is 2.5" too big? I have heard others recommend 2.25" or less to maximise back pressure.

You think the 3VZ lacks torque!!?? It's a refined stump puller! Don't compare those 80kw COMMODORE 3.8L to it...

Yeah as suggested, free flowing exhaust/hi flow cat and some extractors won't go astray. Also some timing tweaking, with a Powerchip or some other device does wonders to torque..AND of course, a 5 speed swap will always be the ultimate.

back pressure only helps with low torque 4 bangers, we need the high end=free flowing exhaust, 2.5 is actually the stock size, but the stock piping is bent strangely so it lessens in size in some places. the only CAI that i know of is my custom (ghetto ish) one w/ parts from autozone/ pepboys.

oh, ^ and i believe he has a 1MZ. ('94)

i think stock for v6 gen4 is 2.25. i almost do 2.5 but with just 2.25 i am happy with.

[Eye8Pussies]

stock v6 piping = 2.25

and yes, lots of weird bends to boot


on the 3vz, the y-pipe isn't THAT restrictive, but on a 1mz, the y-pipe is ass

[kamesama980]

what are you comparing it to? like above, dont compare to commodore (GM?) 3.8. completely different power band, its down low for city driving and less in the upper range. toyota engines have more power mid-high revs than just off idle.

SC or TC wont do much for low end unless you set them up to come on FAST and then die off...very inefficient.

[WestCoastff]

eye8, fuck yea the Y pipe is ass!!! The flow of the Y pipe fucks everything up on the 1mz's exuast system. The headers on it are sufficient enough. all you need really is a Y pipe/exuast. IMO theres better things you can buy for the price of new JP headers....

Nup..he will have a 3VZ. We didn't recieve the 1MZ until 1997/Gen 4.

Yeah, it is definatley the 3vz-fe.

In no way am I suggesting the commodore has a better engine.... harsh, noisy, gutless up top the list is endless. (even the new 3.6 is just as bad)

The camry V6 is a beautiful peice of work, the rush at the top end is amazing (espicially on Shell Optimax 98 Octane - those who havnt tried this yet, do it! huge power difference!)

The only thing it lacks (being an auto) is low revs power. nothing exciting happens untill 3 grand. A manual box conversion would be nice, but pricy. so i am hoping an exhaust will help.

So the wish list goes like this:

Exhaust - needs to increase low down torque and increase high end flow. (is that possible?)

K&N Filter panel - has anyone noticed a difference using this?

Cheers.

WE FOUND A WINNER!! (the transmission is the answer)

and the answer to the list is:
no
no

Terrastrife, I see you have the auto and several mods. What is your magnaflow set-up? you have a K&N filter? was it a waste of money?

and also search for "free mod" or topics by 'toysrme'

In all honesty man, if your realyl after improved torque (and i mean alot of torque ) then the manual is the way to go. Its not THAT expensive considering the improvement you get. I did a conversion on my V6 and all cost me $1100 AUD thereabouts. The rest was just labour by myself! Its really quite easy and having manual 3VZ's around the place the parts on your car could interchange with minimal cutting etc.

On the other hand, when i put my exhaust system on + extractors, it made great improvement to the torque. This is of course on a 2VZ, where the original exhaust design is something shockiing
