Umm, the stock feed/return lines coming out of the tank are flared, so they are not coming off. I have done this (double clamp) setup a couple times before, and never had any problems. I'm not aware of any -AN fittings that fit over the stock Miata lines. As soon as i can, i plan on drilling out the feed and return from the tank and doing some weld on -AN fittings.

Thanks man. It will still be a couple months before i have enough saved up to get the rear end going. I'm guessing about 6 months before i really have it the way i want it... for the time being. haha

Glad you got the turbo back on your Integra. Now take it out to the track!!!


Yeah, that is what i meant. It is adjusted at the master cylinder, and pedal pressure is the same throughout the pedal's entire stroke. It just seems like there should be more. I have a couple V8 friends that have said it felt fine though. I'm sure i am just being worrisome.

Lookin good!

As far as the fittings go, you have basically 3 choices... maybe 2.

You can use a Tube Sleeve and nut combined with a 37 degree flare

You can use a weld fitting

Or you can use a compression fitting.
There is a good discussion on compression fittings here:
http://forums.hybridz.org/showthread.php?p=923875

If the hard line your trying to adapt to is metric, your probabaly best off with the weld fitting or the compression fitting as I doubt you'll find a tube nut/sleve the correct size for the flare fitting... although if you get creative, you might make it work.

Swagelock is the only manufacturer of the compression fittings that I've dealt with. They sell metric tube to NPT fittings. There are other less expensive brands of compression fittings (such as parker) out there but I dont know if they carry the metric tube version.

and use with this to convert from pipe to the AN fitting your hose will attach to:

Don't skimp. That is the exact setup this guy used on his because "they worked just fine before"

Even if i did have a leak at the tank, it wouldn't be much of a fire hazard considering even my exhaust isn't going to be around there. Everything forward of the tank is all Earls -AN lines and fittings.

Dan W- Thank you! That is exactly what i was looking for.

Well, good luck. I was just recommending the clamps because they are only a buck or two and designed for higher PSI (more clamping load)

These fittings work for the NB Miatas. I can't imagine they changed them from the NAs:

Russell fittings:
filter supply p# 640853)
filter return to tank p# 640863)

Then just use a -6 AN compression fitting to attach to the fuel line.

chpmnsws6- Taking a step back, i didn't mean any of that to come across as harsh. I just mean that i'm sure the clamps will hold just fine for now since the car isn't going to be moving for a while. They are there really just to check and make sure the rest of my fittings and lines are not leaking, and to get the motor running. I will definitely be changing my connections at the tank before driving it on the street.

fmowry- Thank you also for the links. I need to measure and see what size lines are coming out of my tank so i can get some fittings. Those actually look like what i had in mind until i switch to a twin intank setup with weld fittings.



Here are some last minute photos i took this morning before heading off to work. I put the fenders back on, and threw the front bumper on to get it off the ground. Also i managed to smooth out the new throttle body I got, and spray it black.

Didn't take it that way at all, I just don't want to see such a nice car as yours with the possibility of ending up in the same fate as that car over a few bucks. If its just to get everything situated before being done right, I see no issues. I'll be done with my soap box so you can get back to building my dream car

Whats the blue miata in the background?

iTrader: (2)

Glad you didn't take it that way. I just took a step back and saw how it could have been taken harshly. The blue Miata is my friends with a 302 in it. It is currently for sale on ebay. It has been his little toy for the past 4 or so years.

Wow nice build. I really want to do this swap. Been doing a lot of research and came across your thread. If you don't mind me asking, where did you get your motor from, how much did it cost you, and what are your total expenses so far? I am fresh out of college, so money is an issue... am thinking of selling my turbo civic to fund this project. I'm new to this whole v8 Miata scene, so any input you have is appreciated. Thanks!

I was on that one until seeing that he removed the suspension & re-installed the stock coilovers. Made me wonder what else may have been borrowed from the car, prior to selling. He did explain why the aftermarket coilovers were removed, but I just didn't feel good about it. Glad to see that it sold & for decent money.

darkmoo - let me figure it up for you. It makes me scared! haha I'm coming into all this from a Honda background too though. I just love the fact of having a rwd car that loves to launch with a stock motor capable of running in the high 11's. Imagine a little turbo setup on it... those are my plans anyways.

LS1-450 - He had the exact suspension setup that i was wanting. We swapped over his roll bar, steering wheel with extension, and suspension to my car in place of my stock parts. He wouldn't have been able to get that much more for the car with all that on there. I made him an offer on it all, and he agreed to it. The suspension is pretty stiff, the roll bar had door bars making it hard for some people to get in and out of the car, and the extension on the steering wheel would have only cramped some people in even more. Me being a small guy (5' 7" 130lbs) and having ridden in his car, i knew it was the way i wanted to set up my car anyways. For how much he has invested in the car, whoever buys it can replace those "missing" pieces and make the car handle and feel the way they want while still coming out ahead.

A couple of those I rounded over just to compensate for the little odds and ends that you need along the way. You won't believe how many trips to the hardware store i have made. Obviously you could save money on the engine and tranny. If i had to go back, i would have tried harder to find a whole pullout with low mileage. I think i would have come out ahead a decent bit. I hate adding it all up like this. You don't realize how fast it adds up. It should be worth it in the end though!

Yah, I understand & that he wouldn't have gotten more with the stuff installed. It just wasn't interesting to me to buy it without the roll bar & coil overs. Usually, the door bars are bolt in & removable. The auction ended yesterday.

What springs did he have, front & rear ratings & length?

dark_dementshun

iTrader: (2)

He had Ground Control coilovers with 300 in the rear and 450 in the front on Koni yellow struts. And yes, the door bars are bolt in so they could have been removed; Good point. I didn't want him to sell the car at all. It was definitely an inspiration in my project, and i think it would be awesome to cruise out to the drag strip or auto-x course with 2 V8 Miata's. haha

Where you note Detroit locker, you do mean Detroit True-Trac, yes? You don't want a locker in that rear end.

Edited for ya. Yes, that is what i meant.

Got all the fuel lines hooked up, and fuel rails put on. Apparently i ordered an adapter fitting backwards for the regulator, so i'm waiting on that to come in.

iTrader: (7)

now, curious why you went with the aftermarket fuel rails? was it so you could add the regulator?

Looks like it's coming along nicely!

dark_dementshun

It was either go with this setup, or the corvette filter/regulator. I just chose this route. I'm more familiar with it, and it does give a bit of visual bling. haha

Just figured out last night that i didn't put the throwout bearing in the transmission. Gotta drop everything back down again. I'm going to go ahead and replace the slave cylinder while i am in there, and clean up some wire routing as well as secure the fuel lines in the transmission tunnel a little better. I'm sure i could have everything apart and back together in a weekend. Just one more setback though.
