Hey guys, i was just toiling through the many pages of ebay crap when i came across inlet manifolds for R33's.

does anyone produce an item for the RB25de or would it be the same as a turbo ones, or would it just not exist at all?

also is there any gains to be had by replacing it on the NA skylines?

(because i remember on my old crossflow after replacing the original with a redline item gains were quite noticable)

Im pretty sure the bolt pattern for the de and det's would be same same, so in theory you could buy an aftermarket one for a det and it would bolt up no probs being an N/A i doubt you would see much gain hp wise but you may gain slightly more throttle response which may not be very noticeable

From what I have heard you will loose throttle response, you wont gain any hp, it will be a headf*ck unless you spend close to a grand for a proper one as ebay ones may need to be altered to fit or wont be nice and flush and you will have leaks. not needed on an N/A at all.

they are the same fitment,and i'd say you would gain power because the intake temps will be lower without that pipe going over an hot engine and with a cold airbox you should see some gains,but you would get lots more power by fitting a turbo

Hello Nikk

Unfortuneately i have also ponderd the same and the answer is no.... the design of the intake pipes ect to to create velocity for the air .... the side mount inatke Greddy ect wont work and u will lose quite alot of power if u tired :) i did hear that one person had ones custom made but never herd or saw how they went.

Spend more and get less. the aftermarket ones seem to be an all loss mod.

I would go for an rb26 system if I was you. just make an adaptor plate to make it work

I was actually thinking about that, cus of the ITB's. Then just move the battery to the boot and chuck together a decent cai and airbox on the left side.

batteries already in the boot miguelegant? and yer putting ibts on is all good and well execpt im pretty sure theyd cost an arm and a leg.

Whats a ball park figure to get them bought fitted tuned and with the correct additional running gear?

4 doors have the battery in the engine bay for some odd reason. RB26 intakes have ITB's. It all just goes into a single chamber, Would be a lot easier to setup and have working properly than a full on ITB setup with trumpets I'd imagine.

    • ADHD in all form isn't about "can focus, or can't focus" or is hyper active or isn't etc.   It's all a dysregulation. Either time feels to be stationary, or time just vanishes in a split second. We are either under focussed on the task at hand (as we're over focussed on our surroundings) or we have no idea an atomic bomb went off beside us as we're so hyper focussed and locked in on things.   Not to mention the rapid fire thought process. What it takes a "normal" process to think up a solution to a problem, ADHD will be able to give you 5 different ways to solve the problem, and the pros and cons of each. While we can be highly impulsive and lack the ability to "control ourselves" we can also become paralysed with the inability to make a decision for ourselves. While most of us have an OCD like requirement for perfection, we lack the ability often to remain focussed to get things to a perfect state. Those with undiagnosed ADHD as adults, can often find the last part actually stops them ever attempting to do things that they have the ability to do, as the reasoning is often "if I can't do it perfectly, it's not worth doing"   As for projects... Ha ha ha, I still need to take the other half of my wall trim down in the Fiance's office so I can paint it. Need to finish digging and running the back yard drains, my R33, getting the Ninja bike registered (now being sold), the moped project, fixing either of the lawn mowers so they're reliable, along with a myriad of other things.   It's why I've been going through lately and just being brutal and clearing projects off that I won't actually ever complete. IE, moped will go to the tip, or be given away, bike is being sold, Subaru project being sold, some parts for other projects given away. Or I've been making myself focus on one thing at a time, by ticking off the smallest quickest ones first.   There's also a reason by our mid twenties we seem to be "know it alls", as we've all been down some of the weirdest and oddest rabbit holes when you follow the dopamine trail. It's often also why we're more a jack of all trades, but not a master of one.   However, pretty much all of my hobby projects, in one way or another, all come back around to automotive. That's my zen area.
    • Remember reading about this not too long ago. been for sale for a long time  this is like when the wife says you need to sell the car so you put it up for a ridiculous price no one will pay
    • You are perhaps suggesting that it is not a super car? Well....it's not an AU.
    • Dropped the MX5 of this morning to get the hardtop colour matched and some PDR done, they are also going to give it a buff to remove some "stubborn" swirl marks and light scratches in the clear coat Over the last few months the poor little thing has copped some shopping centre car park abuse, I try to not park in them, but hitting Westfield's a few times over the last few months has taken its toll, nothing really bad, but enough of a trigger for a "while we're in there" thingie  Once it's back and all the one colour, with a few dents and mark's removed I'll give some of these products a go and see what they're like
