im just curious whether or not the racing sleeves that pineaple racing makes are worth it? does anyone have them in a na s4? how much of a difference did you notice, they lok like they would flow air a lot better than the stock ones, anyone know the price? ill e-mail them later, thanks

I made a set of my own out of nylon. They are worth every penny. The increase in power at redlien isnt very much, only a few hp, but the gains below that are amazing. You get a much smoother power curve, and a stronger bottom end and midrange. Youll never regret getting them.



Heres a pic of the nylon ones I made.

are you going to make more?https://www.nopistons.com/forums/pub...#>/biggrin.png for me! eheh...wil they work good on a unported motor?

They work great on unported motors, as well as ported motors.



I could make some more. $25 shipped in the US.

I have them...best mod for the $$ spent IMO.

ok, what I want to know is, is there a write up on how to do this? like, what exactly has to be taken apart, how to get the old sleeves out, so on, so forth, or if not, could someone who has done it, add a howto on the forum, since I have to change mine anyway, they are fully locked, might as well upgrade.

you need to remove the whole intake manifold to change the sleeves, if you want a write up on that i suppose its doable

****, really? I thought you just had to remove the acuators, acv, air pump, then pull them out. I'm still going to order a set, the pics on the pineapple site have me convinced that the stock ones flow terrible.

they do flow horrible..and i dont know WTF mazda was thinking when they made those

those sound promising, I'd like a set, but seeing as how I lack courage and audacity to go about it blindly, I too would like a step by step process...I feel I can do anything with good instruction, yet not very much on my own wits

lol true that with me too... https://www.nopistons.com/forums/pub...#>/biggrin.png ...it took me 3 hours to find the 5th and 6th port acutators. then Pengaru posted some pics and it was all clear

You guys need to get a Hayes manual and download the FSM too. Those are absolutely invaluable when performing such work. Other than that, we can help with the more detailed questions.

you would be even more my hero than you already are if you would post one up, or talk someone else into doing it, then, Armed with your knowledge, I will do it, and take pictures to assist those others who need more of a visual aide. unless you plan on pulling your Aux ports again, soon, then you can take your own damn pictures.

ive been thinking about it and i dont have pictures, so it might not be that good?



mike

eh, just a general, this part comes off, and be careful not to break this part, cause it is fragile, and all that should get me going, then I can provide pics when I do it, bout time I contribute something to this place.

know i know, and knowing is half the battle! g.i. joe a real american hero! mu ha ha ha ha ha haha ha haha hahahaha

ok i'll start remebering how to do it



mike

Its easy to replace those.Take off intake hose, 1 clamp. Relieve fuel pressure, take off fuel lines on secondary fuel rail. Take off 4 nuts and long bolt connecting the UIM to LIM. Take off 4 bolts and 2nuts holding LIM to engine. You there, put new ones in, done.

While you're at it, you can do the TB mod too and send the injectors to RC for a good cleaning if you can afford the down time.... anything else worth doing?



I want to clean up the engine a bit more. How will removing the EGR affect performance?

Thats exactly what I did, when removing the egr, you will not notice an increase in hp, theoretically it is suppose to gain some by allowing more oxygen into the engine instead of exhaust gases, but chances are its clogged any how. Just remove it and clean things up a bit.

the egr only works at cruise in 5th so it niether cleans the air or lowers the hp



mike

Good.... simpler is better... I'll take out whatever I can.



thanks

Thats what i have heard same thing with the airpump, only injects air into the car in 5th gear. i dunno if i blieve that tho.

I want to put the pineapple sleeves in next month, so if I remember I will take some pics.

I ordered the Pineapple inserts last night... the guy said they just sell the inserts now instead of the sleeves since so many people would not return their cores. Good customer service by the way.... he told me he'd ship them out right away and that I should just mail him a check (he didn't want to take a CC payment) and said he'd walk me through the install if needed.

Yeah Joel is a really good guy. He has helped me out a ton over the past few months.
