Speed 6 CAI best options?

[JDM Speed 6]

Okay so wanted to see what everyone is doing for the speed 6 platform for best CAI options, I'd rather not move to a smaller battery as I have a full audio system in the car, Running a yellow top optima battery currently.

I know Corksport has there stage II kit for $270 I believe, they also sell the 3" and 3.5" power series versions. Has anyone tried to fit the 3" power series CAI from CS on a stock speed 6? How tight is the fitment? What other options is everyone running? JBR, AEM, etc.

Post up pictures if you have any as well of the kit installed.

Thanks in advance.

You should be buying an intake based off your turbo size. Consider upgrading the turbo and intake at the same time. Otherwise you may get an intake now then in the future if you need an intake that will fit your new turbo you'll be buying it all over again.

That's a Great point, I forgot to mention I plan on upgrading to the CST 4 or the BNR S3 at the same time. My current turbo is blown beyond belief, so it needs to be replaced. Planning on keeping this as the DD for a while, not looking to make crazy power, maybe 300ish to the wheels reliably for a stock block car, keep it reliable but be mild bolt on or so. Plan on doing an AP, HPFP, dp, tmic, cai, the turbo upgrade and call it a day power wise.

So just trying to see what everyone is running air intake wise on the speed 6 platform, I see all kinds of support for the 3, but the 6 not so much.

Pretty much all the engine stuff is gonna be the same in terms of intake, turbo, fuel pump etc. When I went from an S1 to an S3 I had to get a larger intake than the AEM I was using.

Also go FMIC. You'll get much better BAT/cooling from that than a TMIC. I never ran an aftermarket TMIC but I know others do and have nothing bad to say about them. I always preferred having an easier access of the engine.

Imo at 300 hp stay top mount

Don't need a cold air intake just need a short ram intake, buy based on turbo size, you want bnrse, get a 3" intake, ramfab/ graveyard performance ideally you want a one piece intake for best flow.

I agree with bunny I'm all about that tmic life especially at those power Goal's, CPE or ets is the way to go for it

On my personal platform I’m running a CST4 with a jbr 3 inch intake. It fits decent, and I didn’t have to minimize battery size, although it is bracketed a little wonky. Still runs and drives fine though. Lol.

I am running a front mount also, so I’m not sure if a top mount will cut down the room anymore. I wouldn’t think so, but I’m sure someone can chime in on that.

I’ll add some pics to show. Ignore the dirty filter!

Perhaps everyone will laugh and say this is a stupid idea. But, what the hell, I'll put it on the table. If I had a mostly-stock MS6, (even with a CST4) I would get the Cobb silicone TIP. It is even 50 state legal, if that is of any value to you. Then modify the stock airbox. Remove the lower echo box or whatever it is called. Open the hole that goes to the wheel-well to the size of the hole in the frame. Plug the other holes in the airbox leaving just the hole to the wheel-well. That would qualify as SRI, and CAI and I think it would provide sufficient air for any turbo with a stock sized inlet. And look pretty indistinguishable from stock.

In fact, if I could sell all the shit in my signature for the money I paid for it, and be handed back a stock MS6, I think I would do exactly that and save buckets of cash. I would still do the mounts I have. (The Damond's are FANTASTIC.) Get the CST4, an upgraded BOV, upgraded TMIC, HPFP internals, a tune, and call it done.

Lol stock sized intake on cst4, if you're going to do that so a bnrs1/2

Well, I figured someone would say it is a dumb idea. You do know the CST4 has a stock sized compressor and designed for stock sized intakes, yes? And the CST4 costs about the same as a BNR stage 2, yes? But, sure, if I did just get a stock MS6, I'd look at either the CST4 and the BNR 2. Either would be a decent upgrade without breaking the bank. And yeah, a stock sized, but less restrictive intake. Sue me.

OP wants to know the best intake, which means it's not a stock sized intake on a cst4 or bnrs3 it's 3" because despite their inlet size they can outflow the intakes so of you want best you go bigger. That being said you can have plenty of fun with those two turbos on a stock sized intake however if you're upgrading let's say from a stock intake you're better off to go 3", if you already have a stock sized maf after market intake and want to save the $ then sure keep it.

If you are going to increase the MAF, then yeah, I suppose a 3" intake would be better. In my mind, I was thinking stock MAF.

A 3" intake does decrease the battery space available by a little. He says he is running an Optima that he doesn't want to change. But, if I recall, Optima batteries are a little smaller than stock, so I think that would probably fit. So probably a 3" intake with 3" MAF would be what he would probably want, I agree.

I still like my stock airbox upgrade idea as it combines both SRI and CAI. And it would all look stock and fit stock sized batteries. So, in my mind, this still counts as "best" even if not "maximum power". In any case, I didn't expect a "warm welcome" to my idea, LOL. I just offered it as an idea and if nobody likes it, fine, whatever.

3" intake fits just fine with the stock battery even 3.5" will fit with the stock battery box and the ecu on the fuse box instead of next to battery.

CAI really aren't needed at all on this platform that's what the intercooler is for, also that stock TIP is stupid restrictive while you could in theory plug a whole and then add another why? The stock air box has ducting that goes to the front of the grill (atleast on the gen2 don't think I've ever seen a stock ms6) in that form it is cold air coming in.

I don't recall seeing an ECU relocate for the MS6, I've seen them for the MS3. I've never actually looked to see what it would take to relocate the ECU so, I don't really know anything about that option. I thought I recalled the stock battery being relatively tight even with something like the Cobb TIP, but, I could be misremembering.

Eh, starting the air off cooler certainly doesn't hurt!

also that stock TIP is stupid restrictive

No shit! That is why I suggested the Cobb TIP. Just FYI, I actually was a parts manufacturer at one time. I released the FIRST available mandrel bent, stock replacement TIP for the speed platform! Search for Speedie6 Turbo Inlet Pipe on 6club. So, yeah, I'm completely aware of the odd stock TIP. It is like Mazda intentionally decided to add a restriction to limit the power or something. I sold around 100 of my TIPs when Cobb or CS or somebody released their silicone equivalent and so Speedie6 parts went out of business.

The stock air box has ducting that goes to the front of the grill (atleast on the gen2 don't think I've ever seen a stock ms6) in that form it is cold air coming in.

To tell the truth, I don't remember exactly how the stock airbox was, but I think it is similar to what you describe on the Gen2. I know there was some second box under the first box, echo box or something. What I was proposing as my "cheap ass intake" was to block off all the holes in the stock airbox, except enlarge the hole that goes where a CAI normally pipes into so that my "cheap ass intake" would get its air from the wheel-well like your average CAI.

 

[Awafrican]

skimmed over the part where you recommended the cobb TIP with stock box, at that point whats the point? stock box is probably the restriction just go full SRI, cobb/ CS stock sized SRI are CARB legal

 

[Speedie6]

just go full SRI, cobb/ CS stock sized SRI are CARB legal

I didn't realize that CS made a CARB legal SRI. I agree, that's a cool option, especially if you live in CA.

I skimmed over the part where you recommended the cobb TIP with stock box, at that point whats the point? stock box is probably the restriction

Did you also skim over the part where it would NOT be a stock box? It would look like one from the engine bay. But its air supply would be the full area of that hole that goes to wheel-well. It wouldn't have any notable restriction for a stock sized MAF.

At any rate, I agree that there are better options now. My mind was more thinking about what options were available when my car was actually stock. I'm not completely stupid, I even was the first to produce a TIP for the Speed platform.

 

[Speedie6]

I see Sniperwolf's pictures with a 3" intake and a stock sized battery on an MS6, so, yeah, I concede, something like that is a better option than my idea. I would just delete my posts above but there is no delete option...

The MS6 ECU is inside the car under either the dash in an awkward location or under the floor, depending on right or left hand drive. Unless I’m missing something here…
