I so finally got my RPMC Turbo Inlet…and what a nice piece it is!! (2thumbs) Thanks Speedy for this product development!!!

So you get a replacement pipe, silicone reducer, 2 t-bolts, and a small hose.

Uninstalling the stock piece was very easy.
-Remove battery
-Disconnect ECU harness and surrounding wiring attached to battery box
-Remove battery box and ECU
-I disconnected the EGR and some other connector for better access
-Loosen all stock turbo inlet clamps, attachment bolt, and small hose clamps

Man, that stock piece is HORRIBLE!!! It has so many sharp edges and bends!!! Uh, I’m glad this thing is out!!!

There is plenty of room to work in; definitely an easy mod if you have an hour’s time to spare. I took a little extra time for the installation since I am anal and like everything to be torque and placed properly.

Never seen the front of my turbo before...damn, this thing is tiny!!! And crammed in there!!!

There is a heat hose that comes in slight contact with the inlet tube. It looks worst when you are installing the silicone reducer on the turbo, but when you install the inlet pipe, it pretty much clears the hose slightly. I see no issue with this. The heater hose also have a protective rubber sleeve.

I put everything back together and everything fit perfectly.

It comes pretty close to the ECU housing…a little too close for comfort, but again, I don’t see any issues with this. It probably has 1/8th of clearance. And if you are that paranoid, you could always wrap the ECU box with heat reflective tape…which actually sounds like a great idea!!! (2thumbs) Though, the inlet does not get very hot, unlike the intake pipes...I wonder if that due to the powder coating...? (huh)

Once everything is put back together...you can't even tell you've upgraded the inlet...

My initial driving impressions…? Well, it totally changed the way my HKS SSQV sounds!!! I don’t know if I’m happy about this or not yet. Basically it changed it from a hitch pitched sound to a low pitched sound. It actually makes it quieter… I haven’t felt any improvement in performance…but that maybe because the ECU is trying to re-learn everything again since I had to disconnect the battery. I’ll give it a few more days and report back. But overall, I am a happy camper!!!! :)

Hmmm (scratch), thats a good question... IIRC, its the same diameter as the Mazdaspeed intake pipes... 2.5" maybe...?

Speedy, can you chime in here!!! (huh)

Updated 8:34am:

Its a 2.5" pipe.

Thats pretty cool, now is that part going into production or was there just a small batch made and once they are gone they are done?

Beat me to it! 2.5".
 
no performance and gain and you don't like the sound, so why are you a happy camper.

It's getting better, since I had to remove the battery and unplug the ECU, all my settings (learning) got erased... I only have 3 key cycles on it...I have 2 more to go; at least. But its definitely getting better...

This morning while driving to work I WOTed it at 75MPH and it pulled instantly and a little harder than before... I definitely like it, if not for performance, simply because its functional and making my turbo's life easier...

So far, the improvements I've felt is instant turbo responce...
I floor it and my DH displays -10.XX to 10 PSI instantly...I like it!!!

Oh, plus if you have an HKS using the stock recirculation hose, the new inlet straightens out the hose very nicely... :D


Where did you get it?
+1 I have never heard of this brand or part.

You can get them here!!! http://www.rpmcmotor.com/product.sc...52818AD.qscstrfrnt01?categoryId=1&productId=1


This surely smooths flow . Are you seeing more boost now? Sure looks nice.

I'm not seeing more boost per say up top, but more boost down low. The turbo no longer has to spool up, at least it feels that way. Now it just instantly spools; kind of hard to believe since this turbo already spools so quickly. (lol2)
Today I noticed my boost ranges in the high 14s to 15 PSI at 6000 RPM and starts dropping to 10PSI by 6500-6700 RPM.
I never really payed attention to it before though...

mazda douche 1: "let's restrict this intake the best we can"

mazda douche 2: "deal"

new guy: "shouldn't we restrict the exhaust too?"
(rockon)

And while we're at it lets make it a pita to tune and use crappy turbo seals so it'll smoke like crazy every time it stops. Oh, and lets use a crappy bolt on this motor mount so the motor will fall out of place while someones enjoying their new car!!!
 
turbo inlet pipe installed woo-hoo

installed the turbo inlet pipe today, easy install - just follow the video instructions.
Initial Results:
1)better throttle response
2) builds boost quicker
3) definitely more turbo spool sound but after it's spooled up about the same sound really except when you are downshifting and engine braking - you get more of the turbo spool sound goin on
4) quality A+++

Will report back after the ecu re-learns, I'm also going to let you know about gas mileage too.

Do this to make sure the pipe is away from the battery box:
a) install reducer on to turbo inlet 100% all the way tight (no gap) - tighten the clamp
b) push pipe into reducer - hard , keep twisting and pushing until it won't go any further - tighten the clamp
c) finish install
d) my pipe is 1/2" to 3/8" away from the battery box !!!!!

All the better for the aftermarket dealers and fabricators to sell you performance parts. I'd MUCH rather buy a super plugged up hotrod that already performs well, that can still add 40-50 HP/TQ for a few hundred bucks instead of someone that has to spend hundreds just to get 5-10 like the NA peeps do. Go Mazda!(naughty)
