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

    • They are under bucket shims. Tomei provides a test shim kit and then any measurement of shim required. 
    • I always wondered how you were supposed to buy a set of 24 buckets and somehow magically have every single one of them yield exactly the desired clearance. I would have thought you'd need to assemble a cam with either 12 "sample" or "example" buckets of known top thickness (or a single such sample/example 12 times over!!) measure clearances at every valve, and then do the usual math to work out what the actual "shimness" of each bucket needed to be, before buying the required buckets to make up he thicknesses that you didn't have on hand.
    • I now seem to be limited in power due to my rev limit/hydraulic lifters in my built RB25. I'm looking into converting over to Tomei solid lifters. Question for anyone that has done the conversion. I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  I don't know where I got this idea, as so far I see no mention of this in any of the Tomei documentation. It just states I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!? There's no way it's that simple, I must be missing something? 
    • I couldn't agree more. I should have started from the get-go with a NEO or solid bucket conversion. I started looking into converting over to solid lifters yesterday.
