jun style intake manifold


What gains would be seen from the jun type mani havint seen much around about them?

NIce price tag for them aswell
 
Yeh never seen that one before....looks nice. Is it meant for Turbo applications? 80mm tb is huge!
 
yeah 80 is overkill. thats y i was thinking if i fitted a 70mm tb from super 90.
i think with this manifold the gains wound be simillar to itb's without the hassle of tunning headaches/
 
If it's a B16, you shouldn't go with more than 65mm tb. If larger you will just loose power
 
style looks similar to veilside manifold for supras,skylines etc but yeah it might be too big for all motor but deff. good for turbo
 
What would be a good size for b18, 68mm or 70mm

Is the jun mani designed for turbo application or do's it work with n/a aswell

these are sold in malaysia. i'm not too sure if the dealer does international posting
 
i run a 65mm TB on my built B18C, was advised by a very reputable company that any more would loose acceleration

car makes 206whp with a very nice shape of graph and strong torque curve, results speak for themselves

unless there was compelling evidence of some R&D for that inlet manifold i would stay clear, inlet manifolds should be designed for each application, just because it's got a massive TB opening and big runners etc doesn't mean it will all work well together.....

yes i have. was actually looking at edelbrock either victor x or performer x.
then i bumped into this which really cough my eyes with it's large runners,manifold and trumpets. kinda like running itb's without the hassle of tps tuning.

btw whats the difference between victor x and performer x?

...but if noone ever tries noone will ever know :) So the topicstarter should be aware that this might not give usable gains, or maybe a lot of it for relatively little money. Imho if you are aware of this risk and want to try it, go ahead by all means and looking forward to dyno results :)
 
Ku-engineering made this inlet manifold.
Here in Italy a couple of guy use this manifold
 
found them too similar looking to skunk2's manifold. and i could not get them here.
actually i wanted to go for an itb setup but there are not many reputable tuners here that can properly tune a vtec with itb. ( might need to talk to Will about this), they can tune non cam profile switching itb great . i know nuts about tuning thus have no idea why the tuners here can't tune a vtec itb.

that's why that manifold looked promising with it's large manifold and runners with trumpets.
