lots of #VZE perforamce parts.. no F?
its for an old truck.. what od you think about shoving them into a camry?

comments?

Anything for the bottom end will work. The problem is that DOA is outrageously expencive!!!

There have been quite a few 300hp / 198kW 3vz-e's built N/A in 4runners (prado's) and Tacoma's. Considering the 3vz-e has 50hp /33kW to make up on your engine just because it's head design is inferior.
IMHO you could get 300hp / 198kW out of your Camry N/A, it's just that noone in the US has done the right build-up to do so.

That being said, IMHO it's cheaper to turbo the car and you have much more power to gain.

Programmable mangement, ported & polished heads, y-pipe, and some intake work will more than max out the stock injectors. If you upgrade them also you should have around 250hp / 165kW at the crank... Give or take a little bit.

would you happen to know of anyone doing serious throtle body (trumpets and all) work on any V6 at all? i dont know what to google for, so i dont know what im trying to look for. no money now, bit ill have a good bunch of money next year (about 5 grand aud) and im looking to keep it n/a. my original mark that i want was 250hp at the crank, allowing for huuge bottom end torque loss, as long as everything above 4k rpm is stronger.

My idiocy but what's a trumpet? I assume it's aus slang for the throttlebody, right?
I don't know of anyone that has had their throttlebody bored out, let alone swaped on a 3vz-fe. It's too expencive a project for way too little gain. (2-3hp max for just a TB enlargement)

here's the great news! You won't be giving up any torque ever ever EVER unless you swap our cams out. If your hp goals are only 250hp. You can reach that without worrying about the expense of higher compression pistons, new rods and such.
A breakdown of what I said before:

A programable engine management (fuel and timing) should be able to tune 10hp out of any stock '92-93 US spec 3vz-fe.

A cheap custom, or DIY y-pipe should be good for 10hp.

Porting & Polishing the heads, intake manifold, and intake air chamber is always hit-and-miss depending on the skill of the guy machining the head. Sean mcelligott got 30hp from his(he had a great shop).
Luckynumber5 should get his head back by Wednesday from his machine shop. I'm sure he'll report on his gains.
I'm hoping to get the last few problems solved on my DIY job this week, and borrow a laptop to retune my SMT-6 for any gains.
Just based on how bad our heads are, I'm now comfortable saying a good shop should get you 20hp, a great one should be 30hp.

Intake - The stock box is nearly unrivaled in actual power. All short-ram itnakes make less power. Most CAI make less than stock also. It basically boils down to one of two camps. The people that buy a $300 CAI, people like me who cut some of the bottom of the stock airbox out/cut the stock CAI pipe out and fit a larger one in. Intake should get 5hp.

If you combine the Y-pipe, ported heads and intake, you should be able to tune the programmable management for another 5-10hp by being able to burn more fuel.
*********************
At this point you should be around 240hp which is means the stock injectors are 100% maxed out. (if they're even in good enough shape to work 100% anymore)They just won't flow any more!!! If you find a way to flow more fuel (pump and/or injector upgrade) you can squeeze a tiny bit more out of your current mods.

You can also use the management to get slightly better power and much better throttle responce by making the car run richer. Instead of it letting it try to maintain a 14.7 air ratio, richen it to around 13.5 from say 3000rpm and up. This way you get to keep it leaner during normal driving for MPG, and still have performance when you're toe is in the gas.

I got 10kw at the wheels from jus an engine management (Unichip), and with the other mods im running about 120kW@wheels, so 165kW at the flywheel is not that hard for NA

[Toysrme]

Wibbit nice gain. Did you get the unichip programmed before or after the mods?

btw, if you ever go back to get them to re-tune. I suggest having them use one of the outputs mimic the ECU's varriable intake signial to the vacuum valve, and have it triggered more around 3250rpm instead of 3800rpm.

ok sweet, now i got a direction to head now!

trumpets, erm... know what the end of a trumpet looks like? what i meant is ya know how 4 bangs do quad throttle body conversions? thats what i meant, but because a v6 layout is different, expecially our laid back one, getting 6 trumpets to fit, let alone everything else that goes with them would be hard. one of those if anyone ever set it up right would give anything in the region of 50-100hp on its own (1.5liter 4 cylinder cars even make over 40hp from them[hyundai excel])

but thanks for the replies, ill give eurotech a call see how much a unichip wi8ll be fitted and tuned. i bet they cant do it so theyll just point me in teh direction of a tuner :P

[Toysrme]

Oh OK i got you on the trumpets now! I would suggest that if you're going to do the Unichip, instead of something you can tune yourself, install it last. That way you don't have to pay them more than once to tune it.
