U are going to put a remote turbo on? Please dont tell me one of those STS turbos as that would just be a pointless setup on your truck.
The TRD S/C has been used to push out ALOT of power out of stock engines...For me going from 150whp stock to 250+whp right now and the torque is unbeleavable. Yes the s/c robs power but the amount it puts back in is awsome. No lag due to positive displacment s/c.
Anyway thats my .02

he said he WASNT going to do a remote mount turbo...he specifically said that too.

Sorry but imo the TuRD blower is a waste of money. For 3G you only gain what, 50hp with no mods? With fuel delivery mods (up to 4G now) what, 100hp?

With 3G in turbo, custom mandrel bent piping, intercooling, and all the other goodies you can gain WELL over 100hp...

I'm just considering a turbo right now and I'd talk to the people at Garret before I put one on. And again, no, not a remote mount. Where I live there isn't much crawling to be done and I think the remote mount might be ok for that if it works as well as people claim. My 4Runner will see more mud than anything and possibly the occasional trip to Tellico.

I'm still really undecided at this point what I'm going to do. I'm worried about everything that I've read about the TRD supercharger. And on the other hand worried about a turbo getting messed up by mud and water. I might even consider a paxton supercharger since I'd be able to use an intercooler with it and solve alot of the problems with the TRD kit. I believe on top of poor fuel supply that heat is the cause of the detonation. Who knows, maybe I'll just stay the course and got with the TRD supercharger just for the sakes of showing that this project is a mini-5VZ-FE.

My question is, is the 3VZ-FE distributorless ignition? the 5VZ-FE is. do the valve covers from a 5VZ-FE bolt right on to 3VZ-FE heads? the ignitors for the 5VZ-FE bolt to the passenger side valve covers.

Dan_90SR5

Yes, the Camry uses a mecanical distributor. I explained a few posts back how you could actually use the stock 3VZ-E ECU with the 5VZ-FE engine by using the 3VZ-FE ignition. I'd have to say that you'll have to do some work to figure out the sensors, but if you wait till I'm done, I'll have that all figured out for everyone. I know what I'm doing is not the same, but I honestly didn't think of this route until Cebby has been brainstorming and trying to get as much displacement and HP as he can, lol. My project will help people go with an easier 3.4L that can be done in one weekend (alot easier than the current option) is you don't rebuild or rebuild before hand. Or people can stick it out with their current engines and do what I'm doing. This will mean more down time, but might come out cheaper. The bottom line is that this project will give people options that they don't have now.

I know that I was a bit long winded in my answer, but wanted to try to explain it all.

Dan you might be interested in this thread over on 4x4wire: http://www.4x4wire.com/forums/showfl...t=1#Post593460
EB has an interesting theory on the 3.slow.

Cebby

Better breathing.... Dan's on the right track!!

Dan_90SR5

I was pleased to see that my fame has spread over to 4x4wire also. It was on the first page of posting and surprisingly not by Mt. Goat.

And yes, Cebby, I think that I'm right too. If you notice the engines and hp specs that the one guy posted for engine of the 3VZ-Es era.......they're all engine with 2 valves per cylinder. He also commented on the Camry engine not making enough power, but 35HP really is alot. I think with the Camry heads, the 5VZ-FE intake (which is alot less restrictive) and some headers.....this engine will be making the expected amount of HP. I'd say between 190-200HP. Not bad when you compare it to the 5VZ-FE.

Dan_90SR5

After reading all of that I disagree with what some of the people were saying. Mostly the negative ones, like the guy ranting about OBDII.......most people that are into modding cars hate the OBDII system. It tries to over correct for mods and ends up giving you less HP than you should be getting. That's one reason why the 3VZ should put out just as much power as the 5VZ-FE. That's also why possibly doing the 3.4L swap my way might make more HP than the stock engine in a newer 4Runner/Tacoma/T100. I could be way off on that though because of the mechanica ignition.

Anyway, I think that my way of doing the 3.4L swap will be the easiest......or should I say mine and Cebby's way of doing it since he made me think of doing it that way. Or the head swap that I'm doing are the best ways to get performance out of the older Toyotas.

Time will tell.

Weasy2k

The stock 5Vz-fe is stock limited by the damn OBDII....however...throw a smt6 on it or something and tweak the settings a bit and your freeing up about 10-20hp to put you around 200-210crank.... orrrr you could go stand alone ....more on that

I cant wait to see the results of your swap

Toysrme

Welp after the hurricane and 3 days without cable I'm back. Weasy2k I didn't pick up much from leaning out my a/f ratio stock like your 5vz-fe's do. Go figure. I guess ours (mine) was closer than what the 5vz-fe is.

Forget any type of "singh escque" design in our combustion chamber. No room for it.

Valves/Combustion Chamber

As is obvious, there is just no room to cut into the heads. Unless someone wants to make some O.S. valves, that are thicker then swap to stronger springs. That way you could groove the valves too hah! (Aint gonna happen, but interesting idea)

I haven't heard anything on the 3.0 modification in a while. Is there anything new to report or did it go to a new thread and I am missing it.
Thank you

Dan_90SR5

No, you haven't missed anything.......the machine shop has been a saga. The engine is being balanced and blueprinted. This is taking forever, so I have no idea when it's going to be done.

The other obsticle is the timing. I have the upper timing bracket for a 5VZ-FE.......I'm not sure that it'll work. I need to get my hands on one from a 3VZ-FE and see if that will work. I think it's different since the pulleys themselves are different. Maybe that will be the key. I'm going to ask a friend if he can get his hands on one. It's a pretty odd part to get in a salvage yard.

Bumpin' Yota

upper timing bracket? what's that?

Can you not just use the 3vze cam gears on the camry DOHC heads to keep the same belt?

Dan_90SR5

Ok, I'll try to explain this the best I can. I will be using the cam gears for the 3VZ-FE heads. That isn't where the problem lies though. In the timing system on these engines, you have the crank gear....the tension pulley.....the first cam gear.....the upper idler pulley.....the second cam gear.....the water pump and back down to the crank gear.

Now with that much explained, here is the problem. The upper idler pulley. On the 3VZ-E, the upper idler pulley mounts to the intake. On the 3VZ-FE and 5VZ-FE, it bolts to the block. The one for the 5VZ-FE doesn't look like it will work. I need one for the 3VZ-FE to see if it will work.

I hope you can visualize all of that. It's kind of hard to explain.

Bumpin' Yota

I cant believe I suggested to use the SOHC timing gear when you are going to use a DOHC setup....i need to think before I post...lol

Im completely with you as I have really done some homework on my (3vze) timing belt setup. ( Ill have to swap the water pump, both idlers, thermostat, and the belt)

But im confused. Doesnt your 3vze block have an upper idler wheel?

Just checking but this is the upper idler right?

Dan_90SR5

Yes sir, that's what you need for the stock 3VZ-E. See that fat part with the 4 holes in it? That bolts to your intake. The 5VZ-FE and 3VZ-FE are different....they bolt straight to the block. That water passage is up higher and different.

Crap, I wish I had compared cranks when I was swapping pick-ups and oil pans between the two engines for my swap. If you could drop a 3VZ crank in a 5VZ, you would have about 3.7 liters and a boatload of torque. THAT would be the shizzy. If not, you can still have a stock crank welded and reground for a few hundred, possibly use the 3.0 rods(anybody know if the deck heights are the same?) and make a stroker.
I'm thinking if you use the 5VZ intake, you'd still run into the hood clearance problem, as it is the intake itself that is taller. I also wonder what the differences between the cams on the 5VZ and the 3VZ-FE. If the Camry engine puts out around the same power with less displacement on an undersquare design, then what would those cams do in a 3.4? Are the cams interchangeable? Could be a cheap way to more power in the 3.4, perhaps? Probably move the power band way up, though. Another thing, are the two heads (3VZ-FE and 5VZ) really identical? Since the 3.4 is a larger bore I wonder if the valves are bigger as well or is it just a small chamber design? Or did I read previous posts wrong about the two being identical? Just thinking out loud here.
I've already finished the swap myself, but I totally support what's being done here. There's little I like better than trying to outsmart the factory with a good hybrid. Like the good old Chevy 383, or the 5S-GTE(as the 2.2 3S is known). Yeehaw for trying, I say. Especially since 5VZ's are only available if someone totals their ride at this point. I'm into my swap about $3500(granted, a fair portion of that was 'upgrades' like exhaust, new O2 sensors, etc.) at this point without touching the internals of a "supposed" 80K mile donor. I have a friend with the 3.0 right now watching this thread who is highly interested in a lower cost method to similar power. We ran light to light the other night and he's a little bummed.

Dan_90SR5

Ok, I really need to stop posting so late at night. What the Hello was I thinking about when I posted a stroke of 92 on the 3VZ? I have looked back and have no idea........maybe I was looking at the new V6 engines.....I'm not sure. The 3VZ and 5VZ share the same stroke. What I've actually read now in hind sight is that the 3VZ has a forged crank and the 5VZ has a cast crank......the reason for the swap was a stronger crank to withstand more HP.

I would honestly like to see a 5S-GTE swap in a truck. If I get this new job I might just try that. I have a friend that will give me a donor 2WD truck. Would make for a good mud or dune truck(in a 4WD).......wouldn't be a crawler at all.

I'll try to find what I was thinking about in that post......it obviously wasn't a 3VZ crank.

I'll get this done as soon as I can for your friend, but I really need to get this timing issue worked out. After that we're in the green. I'm excited to get my engine done. I't's going to run like a sewing machine after being balanced and blueprinted.
