I'm not sure of many, if ANY shops in the USA that are qualified to regrind a 1uz-fe or 3uz-fe VVt-I cam. There are just not many (if any) that have enough experience to make recommendations on anything to do with VVt-I cams. It can be physically done, sure, but that doesn't mean that it'll be done right and to the owners adantage. There's a strong chance that it may be detrimental. If anyone knows of a reputable cam builder that regrind 1uz and 3uz VVt-I cams, let me know because so far, they havent' surfaced.

The VVt-I is a little stuck unfortunately, as far as cams go, since there are no upgrades as of yet. For the Non VVt-I 1uz, there are a few options, however. Kelford would be rated the best since they start from billets.

Show me where to regrind the cams for these prices. You have to measure the lifts and do a little bit of calcalution to get it right.

Crower regrind cams. Though I dont know how good they are with vvti cams.

 

Jason,
Please PM me so i can give you my source. Just give him the specs u want.

 

Cool,
This is interesting. We can test some Vtt-i cams then.

Regrinding them, possibly I could see for $400.00 per set, although those are still bargain basement prices. However, the 'uz-fe family of V8s suffers from lack of lift and lack of duration. Regrinding definitely doesn't give you any more lift, and if anything would take a little away.

Hardwelding is something totally different and can completely change the profile. Hardwelding applies a hard nickel based tri-alloy to the already super hard nodular iron cam. Because of the materials that experienced cam builders use, the erosion and abbrasion factors are greatly reduced. Hardwelded is usually very costly as it very labor intensive, and required much experience to perfrom correctly.

If you're paying $400.00 for a set of VVt-I cams, then I wish the best of luck, and buyer beware. Be sure you know every aspect of who is building your cams, and why the price is so cheap.

Plus none of us really know how a new cam will effect the springs and such. ie durability.

Lift can be accomplish via shims. So what u are selling is not BRAND NEW. They are modified stock. If they are modified stock, please dont advertise them as BRAND NEW AFTER MARKET. This is totally deceptive advertising and you are trying to fool your buyers. If it is hardweld, then please let the community know its modified stock. Modified stock is NOT brand new and its not after market. I am not selling any cams. Why? because they havent tested by our team yet. Unlike some other site. Why other modified stock cam so expensive? because buyers are going through a middle man that is why price just 15-30% or higher. The actual cost of regrind is not that expensive. I think some people with little knowledge and using them to deceive others is very dangerous. Don't let those fancy website fool you. Make some phone calls locally and most of the work can be done. Yes, buyer beware! http://www.tundrasolutions.com/forum...-cam-profiles/ Its advertise as First Pics!! New aftermarket cam profiles for 2uz-fe

 

Ummm, yeah brotha... Aftermarket cam PROFILES....Not new cams.... You sure are confusing when you get upset. But thanks for the link to that thread. That's kind of you.

If you look at Hollywoods above link to Crower, you'll see that their pricing is pretty much on par with the community. Lift can be accomplished via shims, and grinding the base circle down, however this stopgap solution is not the proper way to go. If you think it is, then you and "your team" need to rethink how a high HP engine comes together.

Anywhich way, it seems you have nothing constructive to say. Only negative.

Eric

 

The link is not a problem. I just dont want CL members get hurt by your false advertisements and deceptive business practice. That is all.... now its all up to the readers. I know you the first hand. Especially in our forum. So lets not go there.

Oh by the way, the Brand New After Market 2uzfe cam (lie) what is it working?
Does it fit?
Any knocking?
How much hp does it increase?
What size of shim under the bucket if it would need?
What type of spring would work with it?
Would it affect the pistons?
How would it idle?
What rpm is the power band?

You can not answer those questions because you dont know. You have never try the cams on a live engine. Honestly speaking, I have nothing against you, but I just think you are little too aggressive in marketing your products. Slow down and let your products speak for itself.

 

Please don't imply that my business practices are anything but honest. Not one customer or retailor complaint to date. That not only includes Lextreme, but ALL of the business that I do.

The 2uz cam profiles are exactly what they preport themselves to be. Aftermarket 2uz cam profiles. I don't understand what you're so bent out of shape about.

That's an odd question since the cams in question are heldwelded stock cores. There are no cast billets for the 2uz in existance. So the answer is obviously yes.

A blanket quesion since there are many cam profiles ranging from mild to wild. Properties other than cams are usually a cause of detonation. Improper fuel octane, ultra high cylinder pressures, the usual suspects.. Your answer is no.

Again a blanket question. Cam profiles allow for more HP and TQ production, but it would depend on the profiles of you cam, and the configuration of your motor.

The 2uz already comes with a shim under bucket configuration.. Anytime you change cams, they have to be shimmed properly. For lifts of more than 10mm, a larger diameter bucket is recommended.

Again a blanket question. Stock springs will work just fine. For higher rpm situations, a dual valve spring would be recommended.

Absolutely not. Past 10mm lift, the 2uz will become an interference engine, however as long as the timing belt doesn't get tossed or snap, there is no worry.

Again a blanket question. More aggressive durations give a more aggressive idle. That's elementary.

The last of the blanket questions. It depends on what cam profile you would have. More aggressive profiles yield HP curves further towards the right. The more aggressive cam is not always the best in certain applications.

Sorry, but it looks like I have answered all of your questions. These cams run year in, year out in the Baja 1000 and other offroad racing series'. There is no need to try all 15 cam profiles, and endless combinations since these cams have already been put through extensive testing by the parent cam builder. Even if we did, it would be pointless since every motor is different. That's the main advantage of NOT going with some Joe Blow machinist who says he can regrind your cams for $400.00. The legwork is already done, tested, and holding the checkard flag.

Now I hope this ends our little discussion, and I hope all of your questions have been answered.

Eric

 

Its obvious that you couldn't answer my questions directly. You answered from a theorical point of view. By the way, we know how you run your business. I noticed you are selling the Size Image Twin plenum intake manifold. Has it been tested yet? LOL.. but you are selling it.... Give me break. Buyers beware is all i can say and this thread is not going anywhere. It should be closed.

 

I would not want to spend the time and money trying to figure out what a good cam setup would be for my car. If a company has done the legwork and you know what results to expect, this is worth it to me.


He answered all your questions. Your questions were general, thus he gave general answers. I dont want to see this thread closed due to you loosing your e-temper. This thread has good information.

 

Werd. I woudln't want this thread to go down in the dumps. I'm interested in the cams because I think that's one step towards getting more power (especially for NA).

This one guy gained 8whp with just a regrind on his 3.2L V6 with very little response to mods. (no variable valve timing). That's with intake and stock exhaust piping. I'm sure if we can find a way to work around the vvti mess, 4.0L+ V8 would make at least 15whp, depending on how agressive the cams are. That in addition to i/h/e, holy crap I can't even possibly think of the gains.
