Build thread for my 4th V8 Conversion
People asked and here it is, a build thread. I started my build this weekend and pretty much have the entire "removal" phase done. Next week I'll start modifying the bay for the 331 we're building.
Here's the car Saturday morning: http://carphotos.cardomain.com/ride_...0007_large.jpg Here's the car Sunday night: http://carphotos.cardomain.com/ride_...0028_large.jpg You can see everything that happened in between at: http://www.cardomain.com/ride/3855160 -Jason McCully |
awesome! I'll be following it!

Thanks for the Thread
Thanks for the thread. I'll try to contribute as well if I can figure out how to upload pictures.
I've just begun my build. I'm using Boss Frog kit with Patriot Performance 383 stroker, 500hp small block. This is going to be a long process for me because of required $$$. I am stripping my '90 down to bare bone and will rebuild piece by piece. I have my T56 but no other mechanicals at this point. This weekend I continued working on the hood. Most of the underhood bracing has been removed and the surface sanded down to bare metal. Next step will be stripping the outer hood surface, priming and painting. All of the secondary hood attachments (windshield washer container and associated fixtures) have been removed and througherly cleaned and preped for reinstallation. |
What size of tire is this vehicle wearing in the "before" photos?

That said, I really wouldn't recommend anything over a 205 or maybe a 215 if it could be found for a stock, non-FI Miata. -Jason |

Hankook RS3's, size 225/40R15's on 6UL 15X8 rims. I purchased them that large for the eventual V8 but they surprisingly didn't bog the car down too bad for the few months I drove it with the 1.8 liter.

I used BFG's on my first build and liked them well enough. It's cool they come form the good US of A and all. The car looks a little "tall" right now but I'm sure the V8 will take care of it :)

So how much are you looking to sell this one for?
Laguna blue = 100% sexy |

Laguna blue = 100% sexy If not that will be OK too. I've spent the last 4 years building V8 Miatas but have only had one to drive for about 7 months of that time. We may actually use this one as our "model" and then build another 306 with the intention of selling it in the $23K range. -Jason |
It'd be well worth 26-30k once done! Keep updating it for us please :)

Great thread, helps a lot to see what goes where.
My car had ac installed at one time, but the previous owner took it off. I'm interested in having ac again at some point in the future, any tips for that install? Pics of anything hard to see after the engine is in? I hope to work on that this winter (time? money?) so I'll probably have questions.... thanks |
nevermind.....should have finished reading first! :rolleyes:
|
The hardest part in the AC process is making the cooling fan go on with the AC clutch. I figured out how to do it in a NA01 (1990-93) and think I figured it out in this car. You never really know if a plan works though until you start the car up.
-Jason |
I'll have to ask questions about that then when i get to it ;)
In the meantime I layed out all the parts and such on the bench and kinda mocked it up to see what im working with. I think i have all the pieces, but the condenser looks pretty beat up. Looks like someone pushed a screwdriver through the fins to open them up for more air flow or something. The cooling system was changed a few years ago, so the car probably had some cooling issues. Im not sure whether the condenser leaks or not, but even if it doesn't i doubt it would work very well anymore. I looked through the Monster Miata build book, and judging by the pictures that's pretty much the set up i have (1990 miata). Id like to keep that setup since i have most of the pieces. I emailed the previous owner, and he said that before he took it out the ac did work, but not well. Dont know where the issue was, but judging by the condition of the condenser that may be one, and maybe the system was leaking as well? Been reading at miata.net about ac issues, If i go with a new (junk yard probably) condenser do i have to change the dryer as well? Said somewhere there in a post that it was recommended. Can you charge an ac system yourself? Or does it need to be done at a shop? do you think a used condenser is a bad idea? If not, got any idea what i should expect to pay for one? thanks :) |
Always use a new dryer if the system is opened up. It's job is to collect moisture and once it's exposed to the environment it tries to do just that with the Earth's atmosphere. When you buy a new one it's actually "filled" with vacuum (I know, very bad wording technicaly) and capped. You only uncap it when you're ready to seal up the whole system. I use an old one for fabricating.
After working with both the 1990-93 condensor adn the later 1994-97 condensor I would say use the later if you have the choice. First, its a much better design and actually much lighter. Second, attaching the fans effectivly with zip ties was much easier than modifying the steel "supports" on the early one. Get a new one from Rock Auto or contact planet Miata about getting a used one. I'm sure they wouldn't sell you one they know to be bad. Dryer bottles are about $20 from Rock Auto. The rubber converson lines I can sell you: http://www.mccullyracingmotors.com/i...es/AClines.htm -Jason |
When pulling the A/C system down to 28inches of vacuum, you boil out the water the system has accumulated, correct? I've always wondered why we take such precautions when we are boiling the water out anyway.

Besides, the new one is smaller and has it's own bracket! -Jason |
Jason,
do you know if the different year condensers have different fittings? The reason i ask is that the lines that the previous owner gave me look very similar to the ones on your website. The "appear" to be in good condition, although the metal fittings (90degree elbows etc) can be turned in the hoses by hand, not sloppy or loose, but they can be turned. is that normal? If there is some question about the fittings of the condensers being different (if i have to buy one i'll go with the newer one) or the lines themselves I'll probably just hold off on it for now and start collecting new parts. (like new lines from McCully Racing Motors :D ) As it looks now I need a new condenser, dryer bottle, and possibly lines. Assuming my compressor still works (any way to check it? a bit of oil has leaked out of it in storage) everything else should probably be replaced? What would have to be done to recharge the system when its put back together? Use R-12, or the R-134? does it matter? (If everything else is new im just wondering if it matters as far as what the compressor needs) (I'm not sure if im making any sense, i only started reading about ac systems a few days ago, so this is all new to me. Definitely have more reading to do) thanks for the info! |
The compressor doesn't care if its 12 or 134.
Start another thread with pictures showing what you are talking about. We need to keep this one focused on MRM331's 4th build :) |
Great Post

Killer car build. You have a great eye for detail. That can be a rare thing among builders.
