JUN Performance Parts

[KamikazeR33]

anyone had any experience using JUN gear?

good/bad i wanna hear about it as im thinking of putting alot of JUN gear into a r32 gtr

[JimX]

I've only heard good things about JUN. In fact I've heard of people making their own home-made cam gears and re-labelling them as JUN, because they look kind of similar. ie, not bright pink and green like HKS which would obviously not be the same as a modified factory one.

thanx JimX, thats 1 positive one

im building from the bottom end up

firstly nismo bearings, and a JUN oil pump and baffle etc... then just go upwards from there keeping the block and drivetrain stonger than needed at any point until a t51r spl goes on .... mmmmmm

thats a while away yet tho

keep the comments flowing guys

Just look out for Jun cams in plastic water pipe wrapping like we've been sold in WA that don't work.

[KamikazeR33]

thanx for the advice Steve but for cams i was more thinkin maybe tomei

Steve, how have u found JUN pistons, conrods etc etc?

[GTS-t VSPEC]

I know a few people who haven't found the JUN stuff too reliable.

Do JUN make there own stuff, or is it just re-badged? I wouldn't waste your money on the Jap stuff, go for Argo rods or something like that, they'll be half the price:D

[KamikazeR33]

lol yeah i was thinkin bout somethin like that paul, but just wasnt sure if someone like JUN made better quality stuff

[GTS-t VSPEC]

My guess is that it will be one of the american brands that have been stamped with a JUN badge. And ARGO rods will handle huge power so I don't think you have to worry about JUN ones being of better quality.

[N I B]

Many Jap brands are restamped,but mostly very good quality but at a much higher price We have had good results with tomei cams

the same gos for HKS and the cream of the lot Trust.

Argo rods are sweet.

Only place I know that sells official JUN products in Perth is Speedworks.

At least then you'll know you're getting what you paid for instead of "Jap brands are restamped".

Hi KamikazeR33, we have used Jun camshaft pulleys (they don't wear teeth) and Jun camshafts, never had a problem. We get them from Negun or Greenline.

[KamikazeR33]

sydneykid do u find them to be more reliable than others or is there other cams that u would rather use?

[N I B]

Every Jun cam we have had has come in plastic water pipe wrapping and no spec sheets so we may have been getting ripped of.WE got lots of different timing specs from the supplier making dial in real hard and the Springs had very different seat pressures even with the right installed hights, we have replaced all 4 sets with other brands with good results.Please don't ask were we got them from but it makes you not want to not try again.Make sure you get what you pay for and a garranty.

[KamikazeR33]

thanx for the tip steve, id only buy from a reputable dealer/seller

[Steve]

KamikazeR33, why the taste for Jun? Just out of interest, they seem pretty expensive?

Sorry this is a bit off topic:(

Steve-SST, have you ever found benefit from using adj cam gear on HKS cams? or are they already dialed in from the factory?

Cheers

Steve

[KamikazeR33]

somethin different i guess steve

[GTS500]

we used jun camshafts in a race car and broke through the hardening after one race went back to dealer and was told it was an oil feed problem checked feed put in new cam shaft and failed before we finished dyno runs,pulled cam out fitted australian cam shaft and have never had aproblem.Had jun cams checked and was told that hardening was not finished properly and JUN dealer just said not his problem and has made no attempt to repay cost of failed cams or labor tracking down problem.i personally would recommend you spend you money on other brands that will stand behind there products.

[JimX]

Ah well there you go. Now I have heard bad things about JUN

[KamikazeR33]

thanx for that bit of info GTS500

My mates Drag SR lost its hard facing before it even raced and now has Tomei cams( these Jun cams came in water pipe also with no spec sheet but the sales man is not around any more).Yes i use adjustable gears on HKS cams with sucsses because no 2 engines are the same or reconditioning changes the distance between the crank and cam gears etc.
