oh... whoops.

Well, I'm embarassed, but I'm okay with admitting my mistakes.

Johnny, I'm bailing. eek.

 

no problems...248 would have been killer

 

any updates for the 3.slow guys?

 

So did I miss them or haven't you had a chance to publish results for these cams with a N/A motor?

I had the supercharger and fuel mods but couldn't justify having all that $ and having to use premiem fuel for how little I used it. So I sold everything and bought front and rear ARB's and 4.88's.

On the other hand something like a set of cams I could see using. Ecspecially with the deckplate mod and a slightly better exhaust that I already have it sounds like a nice combination...

 

So does the cost of the cams include valve springs, or do the cams require different valve springs. How diffucult of an install would these be?

 

I dont know why my email not didnt tell me there was replys
Bumpin yota,
3vz-e & 1UZ engines are next! My dads 4runner is coming into the shop today or tommorw night and ill start the tear down.

AK95Taco,
There is no results on N/A as I dont have my mr2 running with this engine yet (as thats where its going to be)

However by looking at the supercharged graph you can see the increase in airflow:



Once again i was loosing PSI in the Red Dyno (after) so you can see the potential of these cams!
Here is proof of that...I wish i could make a dual axis graph so i could plot the psi and power

 

Sorry got cut off before i could answer your question:
The valve springs and cams are 2 seperate items, the valve springs will run about $200usd a set of 24.

These cams do not require the valve springs as they were made to go to the far limit of the stock springs but not beyond

 

My stock springs have 185k on them. Would it be advisable to replace them with the new ones if i buy the cams. If i were to stick with the stock springs is the install as easy as pulling the old cams out and puttin the new ones back in or are there other adjustments that need to be made?

Thanx in advance

 

Yep if yuo dont touch the springs you have to remove the cams
Remove shims from the lifter and install the supplied spacer into all 24 lifters
install new cams and using a feeler gauge you have to measure the clearences between the valve lifter and the cam. If they are all within spec then go back and put everyhting together.
Whatever ones are still out of clearence then you have to purchase shims from toyota that will suit your need (I will stock shims of all sizes soon).

The whole process is a lot easier when using YOUR cam to regrind as the spacers given to you are the same thickness as the material taken off which then pirtty much puts you back at stock clearences.

For you they may be off becuase of the milage anyway so its a good thing to check everything (Suppose to measure clearences after 130k miles or so)

My tacomas springs are 220k miles old and i still put the cams in. I will be swaping them out for the aftermarket ones in future just because I rather have newer parts in there vs having them break....

 

Anything new?

 

This is the dyno run modified to show gains before the PSI Fall off..

here it is




The cams are already for sale and I got 1 set of cores here for people who need the short turn around time.

I will be making other cam profiles to choose from as well. Not all will have dynos until people use them.

 

Well everyone....
some more news on the 5vz cam front....

the cams that were put into my truck are not shimmed right...once i put the truck on the road after the shims there was no noise due to the new oil s/c bearing whine (yea i need a nose rebuild)

But i recently removed the s/c belt to check on things and i heard the typical valve tap! So i go in there and check clearences...well ill be damned...im 5 thou OVER toyotas MAX rating.
I talked to toyota about the problem and they notified me that the shim stock they had were mis labeled and being the dumbass I was never rechecked them after i did my calculations (dont work when your tierd ) ah well im one for admitting my mistakes.

The good news out of this is that I get to go to the dyno and recheck the changes! As that much out kills the performance of the cam!

Oh yea and im working on a semi race profile cam for N/A which should be interesting This is going into my MR2 v6 engine which will have a redline of 7500rpm. Also in the works of Turbo cams as well...

Going to be a busy summer!

 

Good to hear there is even more potential out of this set of cams, I can't beleive nobody else has done this yet. Factory cams are always conservative, especially in a truck motor.

By the way I would still LOVE to see the dyno results with these cams and N/A... With an upgraded intake and exhaust all that is left is the heads/cam and this motor really should wake up.

 

the fact there isnt much is becuase there is not much demand for them...i am doing this mostly for my own fun...and to provide options for people who want to get more guts in thier engines.

Also on the n/a.....just wait

 

are these available yet?
can you list stock 5vz cam specs
IN----------EX
lift/dur-----lift/dur
and yours for comparison?

-derek

 

THey have been for a while, i sold several to mostly people who are working on their engines right now so nobody is running them. I plan to start 2 engines up with them by the end of the month.

Stock duration is roughly 240's new is 267 intake 269 Exhaust (to be exact)
Lift is .330 stock new is .370

I will be doing a large group buy shortly for these as well as the 3vz-e ones.

 

less lift :-(

 

.330" stock
.370" New


My 292's are seeing .470"

 

ahh misread

 

hehe its ok i see where you could have read it wrong. Sorry about that!
