Most of the reason you're not finding very much on the 3.4 for top end parts is because it's not necessary. If you're leaving the engine NA, the heads and cam are already set up for more than enough flow, the powerband is already up there with a peak torque at 3200 rpm. If you're talking about a serious hand built, supercharged, balls to the wall 3.4, then you should be able to talk to your machine shop about porting and polishing your head, or maybe LC Engineering. For the cam, I think I remember hearing about some people sending their stock cams to Crower to be built up and reground.

I think the thing you'll really come up against that'll be an issue is the limitations of the stock ECU. Some years aren't even recommended for the factory Toyota supercharger cause they don't cope as well, so I'm not sure how any of them will do with compression ratio changes, port polish, headers, camshafts, and forced induction all together.

Is there a way to tune the ecu for my needs? I'm used to carburetors and v8s I don't know much about computers and all that crap

3.4 add supercharger underdrive pulley with watermeth injection= 300+HP.

i've seen another thread with the same truck pulling 300HP at the wheels. his sig said it had watermeth injection can't find that thread but you can see what the 3.4 is capable of without getting expensive internal mods.
or you can go turbo and pump up the boost for even more power.

I'm going to do the internals I hate the whine of a turbo

you do know that turbo's dont whine super chargers do. right?
turbo

donomite49

this is not a turbo it's a supercharger and there is no amount of money or internal modification that can match it imo...

look at TA's supercharged runner video's, you can barely hear the heavenly sound of that BA charger, can't wait to bolt mine on.

listen to my 3.4 link in my sig i don't think you'll notice SC whine with headers and exhaust.

After perusing the forums here, I believe this one whole section pretty much answers every question. From what I can see, there are part numbers and all sorts of how-to on the 3.4 swap.

As Donomite said, unless the engine you get needs a rebuild, no need to beef up internals. Check out the google links Black SR5 put up, and also google "5vz camshaft" and look at some of the swaps people have put into the MR2's. Be sure to check out Weasy2k, or Sea2Sky(same person). Don't recall if anyone has asked, what are your goals for this? 4wd torque? 4wd horsepower for mudding? Just a general Toyota hot rod?

toytlle95

I'm starting with a short block so its going to need internals. I just want a mean running Toyota. Something I can take 4 wheeling, mudding, and take it to truckfest at bandimere in Colorado ( drag race for trucks) and do OK in.

3.4 for sure

keep us updated, what you did and how it turns out.

good luck with the build.

Just remember engine components are kinda like computer internals. Just because you bought the "best" individual parts they may not actually work well together. Just FYI it sounds like you have building experience. Figured I would state the obvious though.

If you want torque you can go with OM617 or 6BT they have decent horsepower and out torques the 5vze

Ill keep you all updated and dart a build form for it. This will be my first Japanese motor.

I personaly belive its about gears with toyotas not tons of power u put the rite gear set up on 22re itl go over thro anything. If its a 95 its going to be easier to go with the 22re, as for the 3.4 all i can realy say for it is you wont have the headgasket problems u run into with the 22re sometimes

toytlle95

Your a gear head aren't you? Its all about gears with any vehicle. My uncle always told me something that has stuck in my head. "I can move the empire state building with a Briggs and Stratton motor. As long as you have the right gearing you can move the world."

Short block or bare block? Either way, I don't think there's much in the way of upgraded internals. Still believe your best bet is a nicely machined, polished, and maybe chamfered around oil passages if you know where it's beneficial or have a machinist who does, and then a perfectly balanced assembly. Simple port match, maybe polish, and supercharger if you have the means and the computer that can handle it. URD seems to be the authority on upgrading the supercharger with an extra injector, under drive pulley for more boost, etc. Give them a call or email with your wishes/goals and see what they tell you.

You might just be looking for something larger entirely, never driven a S/C 5vz, so I can't for sure say it'll be enough for you.

Short block and I've found forged rods, aluminum pistons, forged crank, supercharger and a lightweight flywheel. The only issues I'm having is the ecu and I'm looking for aluminum heads and comp cams
