OK, I did the searching and I havent been able to find anyone who put JWT cams into there VG30E. Im removing the heads this weekend to repair the ever popular broke exhaust stud and I figured Id do the cams while I was in there. Im just not sure about paying 560 dollars unless I know its worth it. Anyone??

 

you have some options..i don't know of anyone offhand who has the JWT cams....yet but search around google for ISKY cams and the euro cams.

 

Not a popular mod. I see.

 

Go to z31.com and look in their cam section under performance upgrades or something like that. There you will see most of the options for cams- ISKY, Motorsport Auto and Paeco will regrind your cams, making them by far the cheapest, whereas a place like JWT will make their cams off of billets- making them far more expensive. A mild cam with a little P&P will yeild big gains in the top end, without sacrificing too much on the bottom. Also if you use a mild cam, you won't have to go through upgrading lifters, springs, etc.
There's a lot of info here, just search some more

Well, the JWT cams dont require anything to be changed out. I trust JWT but I wanted some opinions from someone who has installed them in there VG. Im so close to buying them but I want a post Like "hell yeah, buy them. I bought them and now I smoke mustang GTs regularly!" or something like that (and true). I really appreciate the imformation you guys have provided though.

well popularity seems to go hand and hand with level of difficulty/expense of the mod. i along with a few others that i know of are looking into cams as well. from what i've heard and one member has done cams (MAX/OD) the gains are quite noticeable...

 

if I were you I would get new lifters and springs...they aren't that much and TEP as well as other companies offer them at a pretty good price, plus they are added assurance that you don't break anything when since the engine will be revving much higher.

from personal experience I can say that the VG Nismo Euro cams(less aggressive than JWTS grind) with mild headwork and proper fuel/igniton management along with bolt-ons will help you turn some heads!!! Trust me....

 

OK, what is "TEP" and what kind of headwork? Ive read a lot of posts about how any porting is a waste of time on this engine. Also, I dont plan on reving my engine any higher than redline even with the cams. I have 108000 miles and I diont feel like throwing a rod.

 

Da Max- who is TEP? Until recently, I was under the impression that noone made upgraded springs for the vg- but now I've read that paeco and TEP make them? Is it custom work, or an off the shelf part?
Also, are there upgraded lifters that you would recommend, or just new ones? I'm starting my heads soon, so any help would be appreciated.

 

I believe Skymax had the JWT stage II. Good cams really open up the VG's potential.

Nismomaxt, P&P isn't a complete waste of time. Generally, just p&p alone won't give huge gains or anything. Though, combined with lots of other mods/internals it all adds up.

 

Hell with it. Ill order them tomorrow. Then Ill tell everybody about them next week when there in. Thanks for all the help.

TEP= Top End Performance, alhtough the Z31 folks have mixed opinions about them I have had only good experiences talking to Steve Nelson over email about various "dreams" i had for my VG last summer. they were pretty cool people. anyways they do offer various upgrads for the VG valve train such as Stainless Steel Valves and I think titanium valve springs. as for lifters and a mild cam, the concesus that I got is that simple OEM replacement lifters will suffice!

as far as combining cams and to what "degree" of P&P to go with, I can only speak on the gains, not the work invoved(since it wasn't my car). after riding in Max O/Ds car the increase in power and regained top-end is amazing, a whole nother VG. if you wanna get into the nitty gritty you can contact him about it, but that was his old setup....along with the extrude honed intake and stuff....there is plenty potential, just can your wallet handle it!

 

JWT cams are pretty hardcore if you get stage II. Skymax had the stage II's in his car and I have a dyno of the JWT S2 cams in a Z31. There was a 12whp gain at the peak with 20whp+ coming after 6000rpm. IMHO get headwork at the sametime as cams, I have another dyno of a NA Z31 gaining 20-35whp from headwork and cams. However if you are on a budget ISKY or schneider regrinds. Also with any cam install I'd advise you to buy new lifters and if you can afford it new valve springs. I believe ISKY or paeco sells stronger valve springs for the VG30E. BTW I had the isky 262 grind in my 87 maxima and I loved it. If I had bought new valve springs, the engine wouldn't have floated the valves and destroyed the #2 piston .

 

Would you guys recommend new lifters with the motorsport 280 cam? I know I'll get the titanium valve springs, but do I need new lifters?

 

since you'll know you'll get Ti valve springs..care to share where you're getting them from? or are u just dropping words because it "sounds cool"?
Thanks!

 

why titanium and expensive(assumption), when you can get Z32 or SR20? wouldnt it be alot easier(and cheaper) to frankenstein from other nissan motors than the get aftermarket? just throwing out questions...
nismo87, do you still have those SR20 springs? soon after christmas i'll have the money for them.
also, any good sites on how to port and polish? i plan on buying a second set of heads/intake to work on since i cant afford downtime.

 

It would be easier and cheaper to get stell Nissan springs, but titanium ANYTHING is way better for two reasons..it is half the weight of steel and twice as strong. If you are camming an engine, lighter vlavetrain means it will rev easier and much safer (faster spring response to changes in direction) to a higher rpm. Paeco makes EVERYTING for our (and most other) engines. They may not be the cheapest, but it a one-stop shop for all engine needs, from titanium rods to titanium valve keepers. In fact, this might be a good idea too. If you can't get big $$ springs, go with the keepers at least. They are strong as hell and will save a ton of weight. Actually, a few grams, but when you consider the total wieght of the moving vavletrain, a few grams is a large % of that total. Honestly, I would just send my heads to Paeco and have them do it up right. They can even install larger valves if that's what you want. The price on headwork is right too. There basic modified head package is like $750, Add on whatever you want. you can get heads that are DONE for less than a grand. Well worth the money, considering they gaurantee their work, and all you have to do is bolt them on. Also, if you are going to do the heads fully modded, P&P cams, valvetrain parts, port match the intake while it's out (this is an easy do it yourself, no chance of f'ing the flow up, like there is if you try to port your heads without knowing the right way to do it). I really suggest yo usee a pro about porting htese heads. At least get some info from someone like Engloid who has extensive experience porting heads and initakes on VG engines. Finally, if you are camming it, those adjustable cam gears Morgan is selling are a very good idea. Even if you set them to zero and install just like they were factory originals, at least they are there and when you have the tiime and $$ to dyno it, you can optimize thos nice new cams and modded heads.

 

i thought we were supposed to say stuff like that to scare away newbies

 

Dan, read the whole thread next time. Ok bud?

originally posted by DA-MAX:
"anyways they (TEP) do offer various upgrads for the VG valve train such as Stainless Steel Valves and I think titanium valve springs"

 

website?

 

I tried to e-mail this "Engloid" at an e-mail address I was given and it was returned. Any ideas? Also, whats the turn around on a set of heads done up by Paeco. Thanks,
Dano

 

Just call Paeco- I called yesterday and they were very helpful and knowledgeable- The guy on the phone said they had built a 1400 hp vg30de
I'll ask today about turnaround time though

 

could you get me their email address or something? phone number will do also..
thanks (i know i should just search, but i'm late for class and lazy)

 

Paeco

 

I plan on going with Paeco for the heads, maybe even the short block. I spoke ot them on the phone too, they definately know their stuff, ALL the tricks. When you get right down to it, for a few hundred more than it would cost to DIY, you get a Pro machhined, assembled and warrentied engine. I'm likley going this route when it's time.
