Hey guys.

I know that the factory speakers are 6.5in with a depth of 57mm.

However I am looking at a pair of speakers, the Polk Momo 650, and they have a depth of 61.8mm.

I am looking to run a set of these both in the front and the rear of my GTR33.

I am wondering if the extra 5mm will fit in there with little issue? Or do I really need to find a different speaker with less depth?

Thanks a lot for the help guys!

I've never pulled my door panels off yet, so i dont know what's behind them,

But when you add the 6mm MDF Spacer, wont this push the speaker out into the speaker grill? Or is there empty space between the speaker and the grill normally, which you make use of?

easier to remake the pod. then you can fit whatever you need to. in regard to the polk speakers. 20mm total thickness will do it. be sure when you make the new pods that you put the pocket end back on.

Chris, are you talking about the pod inside the door, removing that and making custom?

yep. when you pull one apart next have a close look at it. what I am saying will then make sense.

mine even reuse the stock mounting bolts.

tried the way you do them got a complaint that a garage remote went into the door so I changed how I did them. no hassles now.

the R33 that i put the Alpines into had the factory pods, we made a 6mm speaker ring to sit inside that. took 10min max to make a cardboard template, trace that onto the MDF, cut the MDF, sand the edges to get rid of the flash, and screw straight in with the speaker - into the factory holes.

only reason we took the factory pod off was to put sound deadening on the door and inside the door.

ok I see what you are doing. they won't clear the back of the pod. for a 6.25" (IE alpine) that would work. when you put a 6.75 (IE VDO or Blau) it doesn't. thats why I remake that pod. the MTX ones will drop into those holes easily as well. done a few of those.

as a second for this..

the vdo mps1700 splits sound great in an r33 and offer awesome bang for buck

whats the mounting depth of VDO and Blau (havnt installed them as yet) I know Fusion 6" are bloody deep, probably a smidge deeper then Type R's

    • It's funny, as Ive seen plenty of people use them in cheap builds on YT. And they actually go okay, even though a lot of other maxspeedingrods stuff is terrible. Those turbos seem reliable enough, the only part being, a good quality turbo that is "identical" to it, will out perform it day in and day out. In both a lower boost threshold, and the ability to flow more air at the same boost pressure. As a cheap cheap replacement, not a terrible choice. For cheap and shouldn't blow in a day, not terrible (like other eBay/Temu turbos) for low cost and still decent performance, that's where the question comes in to play from the results I've seen. I'd actually find it hilarious to buy one, and strap it to a paddock basher or some other cheap as POS originally NA car, and send it to the moon!
    • The maxpeedingrods turbo is cheap and bolts on to stock parts. I think you just need a bigger silicone coupler for the intake. Its a cheap china turbo, but it's been running on mine for almost 3 years at 16-19 psi.
    • What do they look like right after you've tried to start it with everything connected? Also post photos of what they actually look like.
    • Also wanted to say, my new spark plugs are blackened looks like it's very rich. I have splitfire coilpacks but stock coilpack loom and ignitor. I tried directly grounding the ignitor ground to body as well.
