My "Quest" for low budget MPI..Mazda Intake.


Recommended Posts

Not 56K friendly!

 

After seeing alot of success stories from others, I have decided to get back on the project. This is about ten hours of work fabbing the plate and removing unneccessary webbing on the intake. I don't have a time frame of how long it's going to take to finish this as I'm on a tight budget. I'm just doing things slowly being the less costly thing first.

 

Total money spent: $0

Total man hour: 10hr

 

What ya think? If there is anything you see that need perfected, let me know, as I'm a newbie on this. :wink:

Thanks for the concern, as this is what this post is about, spotting the flaws. :wink: This is just a mock-up(sp). The final finishing touch should look better and should clear the brake booster, the least of my worries. I'm trying to figure out how to make a thermostat housing for it now.

 

 

 

I can mill anything out if need be.

I don't think so AJ. It's not going in my car, I'm leaving her all original. :wink: I'll have some money next year for a shell and it'll be my fun car.

 

I'm having issues with how to make a thermostat housing for it. If I were to use the factory distributor, it'll be a bit more tricky to make.

 

I also can't decide if using the Mazda MX6 TB is the way to go or not, as it got two flaps. I got three TB....a '90 Protege, a 240sx, and the MX6 TB.

 

Does any one know if either TB is better than the other? I'm thinking of using the 240sx TB, also if anyone with a custom made intake can give me an idea of how to make a thermostat housing it would be helpful to me.

I have a few water necks from the 4g63.

Or I can have one fabbed.

 

I can ship you one for 12 bucks shipped.

I can get you pix in the morning.

Let me know if I can help.

Yes, please provide some pics. :D

 

As you can see in the first pic, I'm not going to machine any off till I figure out how to adapt a thermostat housing here.

I live about 1 hour up I-24 from you.

How well do the ports line up?

U can use a remote t-stat housing for the t-tat and just use a strait pipe out from the head port.I think some 318 4cyl bmw's use something like that If you can find a junked one.

If you're talking about the intake port...look at the second and third pics...the second id the end ports and the third is the center ports.

 

If it comes down to it I'm going the remote type for sure. I think using the Caravan water neck as the lower and Starquest as the upper should do the trick.I really want this to be as clean looking as possible.

 

As far as TB's go Couth, aren't Mazda and Ford one in the same now?

 

I think on the Probe and MX6.

 

I don't really know the ideal way to go about the TB.....dual flaps or single flap. I guess I'll try both eventually. :wink:

Ok so I am also tring to go this route and I think I have found a solution to the t-stat housing. Looks like to me that a t-stat housing off a 1.6 miata could be welded to the intake flange. And they are only about 30 bucks used.

Hmmm...interesting. I'm glad some few of us want to do it a different. :thumbsup:

ive got one of these done as well..

the supra and rx7 injectors are a direct swap... into this manifold..

 

Theres also an issue with this manifold that nobody has been talking about.. its the fact that the manifold itself has 2 different versions from the 89-90 and the 91-92... probe gt/mx6 gt with the f2t motor

you want the smaller of the two... the larger will not line up... and the smaller is ont he 89-90

couth, some people using the big t.b's have a problem on the tip in. like when you first nail the throttle, the car gets a huge gulp of air and kind of coughs out for a moment till it gets it all together then runs like a bat out of hell. you might want to think about the two flapper t.b. depending how it works. do they work simultaneous or could they be made to work progressive? if they can be progressive then you might avoid the tip in problem some people have but that is only with the big t.b. the ordinary ones everyone runs is the ford 4.6, 65mm t.b. so maybe measure them and see which ones are going to be comparable size wise.

also i know my car is extremely responsive and is a bit tricky to drive in the rain and in traffic, you might find it easier to drive and control the power if the two flapper is progressive.

I've been doing a little research, and I'm only repeating what I've found, and it appears that any MX6, Probe or 626 built from 88 to 92, non-GT will work.

There are half a dozen at the local pick-n-pull and I'll be running down there tomorrow to check them out.

Derek, 89Palermo ran down there friday and yanked one out of a 91. We spent some time fiddling with it on saturday and it looks like what the other guys have. He bought a gasket before he went so he had something to compare to. I think it just needs to be a non-turbo intake from any of those models and years listed.

i wonder if thats the distributor issue... might have to make another trip down there and check out the 89 they had. i wasnt sure of the year of the car but it sure looks darn similar to all the others. maybe the bend in it is more extreme on the one ive got, hence the problem clearing the distributor? hmmm

 

looking at it closer... i think its the wrong one grrr
