cold air intake question

[TurtlesRun]

IM about to buy this CAI for my 88 mustang 5.0 http://www.summitracing.com/parts/BBK-1557/

MY question is my car is an 88 and has speed density. is there a way to convert that to mass air. Is it expnsive if i can and is it worth it

[1lo94]

yeah they make conversion kits go to latemodelrestoration.com, there the best site for foxbody restoration and acc. i have spent tons of money there

[brown7]

hell yeah its expensive.

and hell yeah its worth it.


instead of converting, why not put a spacer in place of the mass air and roll with it like that?

buut...

from my understanding speed density is pretty much tuned to set perimeters, unlike mass air which goes off of incoming air flow etc. don't think it would make a difference but i don't know 100%.
my 86 ran rich when it was speed dens and after i converted it.

You car will be faster just by converting!

[TurtlesRun]

went to lrs.com great site.. Im lookin on there now... what exactally am i looking for. i found mass air meters. and thats reallly about it. can you point me in the right direction. and another questions when you look at that intake. what is that thing in the middle that connects the 2 pipes.

[brown7]

that would be the mass air meter.

you could always go with the ":1986-88 non-mass air cars must use BBK-1558 adapter." to make yours legit, which probably is just a spacer.

i cant find the kit, but i remember it wasnt cheap.

[TurtlesRun]

i think i might of found the stuff here is the link i found http://www.latemodelrestoration.com/products/Mustang-Mass-Air-Conversion-Kit-And-Accessories

the main things i got out of it were i need the harness, the calibration tube. and the computer. is this right

[brown7]

sounds right. if you cant find the 89+computer harness i believe the piggy back is needed.

The calibration tube is only needed depending on the mass air meter. a stock89+ meter doesn't use tubes, but is preloaded for 19lb injectors. you cant just swap out a tube.

if you can pull the computer+harness, intake tube/meter, that should be everything. thing is last time i checked our junkyard didnt have shit for foxbodies, and if there was one it was stripped.


if you buy the harness+ computer new yes you would have everything but thats 500+bucks...plus you need a stock meter.

where is that jankyard....didnt know if they had one here

[brown7]

its on fm600

Just get the BBK 1558, it is a spacer that slides in place of the mass air meter for the earlier speed density cars. Unless you are wanting to upgrade to mass air I wouldn't mess with it just to run a CAI. I had a buddy that went from speed density to mass air and it took him a few years to get all of the kinks worked out.

[SeeingRed]

It's not that big of a pain to do the speed density to mass air conversion. You can get most of the parts you need on Ebay for CHEAP and it takes an afternoon and a six pack to do. My 18 year old brother did it by himself with me watching from a lawn chair with a six pack of Leinenkugel in Aug. Car ran like a champ after.

If you spend the extra money and buy a C&L MAF meter, it DOES have tubes and you CAN swap them out in the future.

[brown7]

just get the spacer for your cai and stick with speed density. its not untill later mods (i.e. the cam you want//internal) you would need to get it tuned as speed density/converted to mass air.



stock meter is the same size (55-60mm?) as the Tb and EGR Spacer, and even then the stock intake inlet is the same size as the TB so it is all still (55-60?mm) inside. just a thought when you upgrade the rest of it down the road.

i put in a TB and matched the intake to the gasket for the new TB and worked like a champ. was it actually the same? no not really but there wasnt a giant wall around the edges anymore.


dam i want another 5.0 lol..so easy to do everything :(

[SeeingRed]

Stock throttle body inlet for the 5.0 cars was 48mm.

[TurtlesRun]

found the kits on the internet. says they are brand new. fiveologyracing.com they have sensors that go from 73mm all the way up to like 76mm but you need bigger injectors. i took it that my car has stock 19 lbs injectors. what is the upside to putting in bigger injectors. do i want to put in the bigger injectors to get the biggest sensor. does the big sensor really matter all that much. does the bigger sensor allow more air?

[SeeingRed]

You don't need bigger injectors at all. On a stock motor there is absolutely no upside to putting in bigger injectors. You can get a bigger MAF and still run 19lb injectors.

[TurtlesRun]

Yea i saw that after i posted the thread and im fighting the flu so i didnt feel like changing it. anyway if i do more major work. heads cam etc. Am i going to need bigger injectors. it kind of seems smarter to replace the injectors. now and get a big sensor say 32 lb injectors, and 76 mm sensor. than replace the injectors when i do heads and cam, then i have to replace the sensor again. if i get the senor that fits my stock injectors then sometime in the future get bigger injectors will the sensor still work

[SeeingRed]

If you get an aftermarket MAF, like a C&L, you can swap out the tubes later. Your car will be HURTING and running SUPER rich if you go with 32lb/hr injectors, even with the matching MAF. That's WAY too much gas for a stock motor, no matter how you slice it. Planning ahead is one thing, but if you're planning on doing H/C/I later, what difference will spending $300 on new injectors be? It's NOT smarter to replace the injectors now because your car will run like total shit.

Even when you do heads, cam, and an intake, 32lb injectors will still be too big. I ran 24# injectors on a 331 stroker and was only at 75% of the injector duty cycle. You don't need 32lb injectors on a 302 unless you plan on running a big dry shot of nitrous or 8psi on a blower.

Like I said, you can get a C&L MAF and switch out the sample tube any time. It's held on with torx bolts and takes about two minutes to swap out. Once you get your car swapped over to mass air, get a 76mm C&L with a 19lb tube, then later on when you NEED more gas, get a set of bigger injectors and the right sample tube for it.

[TurtlesRun]

I see... so you would go with the 76mm as opposed to the 70mm bigger is better right?

[SeeingRed]

Not really. I'd go with the 76mm because the only thing bigger is a 90mm and if you're planning on doing H/C/I later, the 76mm will be fine.

[NeverEnuff]

Ill make you a CAI for cheaper than those kits...with a MAF. lol.
