Jesus **** m.net is useless. There are different answers for everything.

I have MS, so I don't really have to **** with the throttle body (using the 99), and I bought the FM bracket for the coils, mount brackets, and the throttle cable.

For my 1.6 car, I'm confused about pullies, and the fuel rail. I have a 99 fuel rail of course, what do i need to do with it to make it work, or should I just buy an aftermarket one?

sorry to be a worthless ------, but the more I search, the more fucked up my tiny gets.

 

if youre using a 99 intake manifold, you just use the stock 99 fuel rail. You MUST use a stock FPR from a older model though because your car has a return line while a 99 miata got shitted on with a returnless system. just rig up the same way FPR, fuel line and return line, should fit fine. if not, just use the right fittings and do a DIY dual feed system and change your fittings all together.

oh yea, youll need to figure out a way to make VICS function too.

 

vics is already figgered out. Can I use the 1.6 fpr or doe I need something else?

 

I'm 99% sure you need the FPR from an NA1.8. I'm 99% sure the 1.6 will not fit at all.

The NB1.8 FPR will not fit on the '99 rail because the pipe coming off of it will hit the head. You can cut the pipe to fit, but you'll want to flare the end again. The NA1.8 is a perfect fit (99% sure).

For the return line, I'd just find someone parting a car and get the stock return hardline off of it... ziptie it to the feed line. That way you don't have to buy 10ft of fuel hose.

 

Doesn't the FPR mount directly to the fuel rail? How would that work with the 99 rail? I have the same question, because I will hopefully be in the same boat very soon.

BTW Hustler things didn't work out with John Day unfortunately. I changed my plans a little. He is a nice guy though, and easy to work with. I'll hopefully be in the DFW area this weekend though to pick up an engine.

 

Never mind, for some reason I thought the 99 didn't have a fuel regulator at all, but that doesn't make a whole hell of a lot of sense.

 

I'm getting my motor on saturday too. Holler at me if you want to do lunch.

 

nevermind. Its going to be a bitch to get one apparently.

 

RockAuto has a stock-like (not oem) NA 1.8 FPR for 81.99.

I'd be down with lunch if my plans work out. I can help unload your engine from the Miata too if you need it. I'll have mine in the front seat of the beater Civic.

 

I'd like to find a used one and save some cash considering I forget to get my injectors cleaned.

Cool. I live in Lewisville, picking up the motor in Richardson, and dropping it in Irving if any of that makes sense to you.

 

I've got a 95 and a 96 sitting out back. Where is the FPR located? I would guess I could come up with one for you, plus the hard line if you wanted. Shipping that would be a bitch, though.

 

I'll pay. Let me know what you want to do. I assume on the back side of the fuel rail.
I think this is it:

 

Let me look tomorrow.

 

Got one. Won't you need the 1.8 NA fuel rail as well? The NB rail won't have the line for the return, unless you are modifying it for the return. Plus, I don't know if/how the NA FPR will fit on the NB rail. I never looked at my NB to see how it mounted.

PM me if interested.

 

euro spec '99 miatae do have a returnstyle fuelsystem IIRC, maybe try to snag one of those rails?

 

The only NB that was returnless was the '99. All other 1.8's were return-style. You can buy a 94-97 or 01-05 FPR and it will bolt right up to the '99 rail. I think there was something else special about the mounting of the 99 rail that made it incompatible with other intake manifolds. (99%) Only the 94-95 has a discharge pipe that will clear the '99 head properly. You can modify any of the others to fit by cutting the pipe shorter... but again, you then need to flare the pipe for safety so the fuel line doesn't pop off under pressure.

Hustler, I'd give Planet Miata a call. They get $35 for a fuel rail... specify the year, remove the FPR, and sell the rail in the classifieds for somebody looking to do a dual-feed mod and wants a spare rail.

 

LOL, I didn't read most of the posts in this thread, but do ignore most of what Sam said.

Sorry if it's rehashed. Again, I didn't read the ******.
-You need a 99-00 rail with a 94-97 FPR
-You need a 1.8 IM, 99-05 will bolt right up. If 01+ remove the butterflies, If 99-00 I'm not sure if the butterflies should be removed or if VICS should be utilized. 94-97 will also work, but take a bit of fabrication
-Your MS will run any of the 1.6 or 1.8 TB/IAC/TPS set ups, but you'll need to tune it for any of the NB stuff.
-You need a throt cable relocation bracket. FM has a nice SS one.
-You need to figure out what you'll do about EGR. Removal and block off plates is IMO the best thing to do. FM has a plate that's an easy, bolt on affair. Or you can weld in a nickel to the port.
-You need to figure out what you'll do for ignition as your 1.6 coil pack won't bolt to the 1.8. I went to COPs so no worries there.
-You'll need to extend your CAS wiring.
-You'll use the metal motor mount brackets off the 1.8

You probably should read the swap info on FM's site and pick up a copy of Kieth Tanner's older book. It has a section about 1.8 swaps, and I know you'll be able to follow it because there's pictures.

 

Looks like we just found out who hustlers significant other is...j/k dont e-thug me...

You have to use the 94-97 FPR, and I have one as well in case Seint passes before you decide to get it, no offense Stein, but you made that thread yourself yesterday (40+)

I found the 1.8 swap fairly easy to do, but the guy I helped bought an FM kit or something. It included eveything you need except gasket maker, yes you will need this.
As far as advice goes, only thing that I found weird is the two piece manifold, and that really was no biggie, you just have to remember that you can't pop off your rail anytime you want to, the mani will not let you.
Also, use vaseline (do not use silicone spray) or something to lube the O-rings on the injectors when installing, I had one leak b/c i forgot to do it, and guess what. i had to take the intake mani apart again...that's how i learn though, the hard way.

 

awesome, so now I have like 3 answers on what fuel rail and what fpr I need.
