I think if those cams could be had at a reasonable price, the market for N/A 3.4L's changing cams might even eclipse the S/C'd guys. Most of us do just use it for a daily driver with occasional towing or maybe a small amount of offroad (again low end torque would help alot)......not to mention alot of people don't want the expense of running the S/C and being forced into hightest gas only.

 

I agree with mtl_4runner, and that covers alot of us. I know alot of guys in Australia with the 3.4 V6 in our hiluxs that are either converting them to LP Gas to save on fuel expense or just sellin and getting turbo diesels because of the 3.4's lack of bottom end torque and when you rev her abit harder they drink heaps of petrol. Could be a potential export market for ya if you could get decent low down torque out of it thus improving economy. I'd love to hear more on the progress of this project.

Heres some pics of my Hilux, just thought you might want to see what Ive done with it. Would love to go higher but 4"lifts kits are extremely expensive here and the traffic authorities are getting very tuff with extreme looking trucks, might just go a 2" bodylift next and 285/75x16's, plus 4.5 gears

 

*drooling* I'm really digging the side tubings. I cannot see the picture really well is that a tube step bar or factory running boards? Nice Rig!
Sorry for the hijack.

 

id be in the market depending on cost.. however I dont have any cams to send because this is my DD and I cant pull the head off to do that.

 

Hey all,
I'm sure you all are aware of this but I saw no mention of it in the talk about cams, so here's my 2 cents worth.
The 3.4 is a clearanced motor, meaning that the valves will not hit the pistons in the event of a timing belt failure. The addition of higher lift, longer duration cams will very probably cause interference (damage) between valves & pistons making contact. This can happen at any rpm, not just under power.
Be sure to do your homework before making this particular mod.

 

well of course no cam would be offered that made a valve contact a piston, lol.

im not just making up a profile, and trying to sell them...

 

is anyone still interested?

 

does anyone want to possiby get this going now?

i need a set of cams to send to my manufacturer, also a set of heads and valvetrain would be nice so i could look into getting porting services done.

but i would be willing to offer valve jobs almost immediately once i had a set of heads to get things right on.
BruceTS was supposed to send me a complete set of heads but i think something came up with him.

NEED A SET OF COMPLETE HEADS, possiby from a blown bottom end....

 

Check your PM....

 

anyone have a complete set of heads in decent conditoin to give me for R&D.
you would get the cams back but that pretty much it, as the heads i would need for much longer.

please PM me.

when i get into the market for cams, i'd like something that would give the truck a nice idle, and a higher rpm rasp. call it form over function, but c'mon...it's a 6 banger...

make adjustable cam-drive sprockets.

 

thatd be super hard to make and even adjust as the sprocket is cast to the cam.

 

I don't think it is impossible. I know that some of the Ford Mustang Cobras had adjustable cam sprockets...Might look into that DOHC design.

 

right not impossible, but if its this hard to sell cams, then i think itll be even harder to sell adj gears, since thatd require machining of all 4 current cams, ill look into it though.

thanks

 

No big deal. I think the 3.4 is just a motor that can't possibly have huge gains from cams Normally Aspirated. FI possibly...but not NA. THat is why it is tough to sell these cams.

Good luck though!

 

Thats cool when its time for a new engine ill think about it.

 

id be making two different cams, NA and SCd.

SCd would be the first since itd probably be the more popular.

 

anyone?

 

Still can't get anyone to bite? Maybe you should sweeten up the deal....

 

As of right now my motor isn't turning. I'm banking on the fact that it is a bad starter but I'll let you know if things don't go as planned. I'm S/C'd w supra injectors etc... so there could be some descent power gains available for me with this upgrade. Just an fyi, there was a guy that found a rolled 4Runner for $1,200... You could strip whats left and pay for half and have an entire engine to work with...
