K-Town Powder Coating

Hello,

Long time reader and first time poster. I have saved the heart of a very rusted out 1990 Miata power train and am using it in my Locost build. I am planning to run a T25 talon turbo on this setup and just looking for you smart miata people to check my list to see if I have everything I will need.

T25 turbo
Weir Log Manifold
custom DP
1.8L injectors
external walbro 190 fuel pump
MR2 SC intercooler
MSD boost control unit to retard timing
RRFPR
BOV off a G1 Talon
water lines/ oil lines

He is a few picture's of the build











Welded up the manifold but no outlet on it yet. I will be ceramic coating it once it's all done being welded.

do you have charge piping setup?

also, do you have all of that stuff? i have 1.8 injectors and the fpr if you need them

I trust you know im local.

K-Town Powder Coating

yes I have all the stuff. I bought 1.8L injectors yesterday for $25

Looks good, some minor concerns about the chassis. If it were me I would triangulate the engine mount, but that's just me.

The engine mounts have been changed since that first picture. Much stronger now

Looks cool. I was going to build one before I found my Miata.

Word of advice. Get a facemask. Driving a locost will fill your mouth and nose with grit; seems every little piece of road crud gets sucked into the cockpit.

Build and list look good. I'm not really seeing anything missing. I assume you didn't mention charge piping as it is a simple fab part.

Is there a reason with all the diy stuff you're not using a megasquirt?

K-Town Powder Coating

yes I have the piping to make the chage pipes.

right now MS is not in the budget..... but down the road it will be added. We had the RRFPR and the MSD from an old miata SC kit we had.

Your list looks good for a low-medium boost setup. The hardware could let you run as much as 12psi with the biggest limitation being the turbo and injectors. That turbo really falls flat on it's face at 14psi with limited gains starting at 12psi. Is your Walbro 190 really external? Around here, we typically use Walbro internal pumps that are rated 190lphHP(Hi Pressure) and the regular 190lph low pressure. I'd recommend you be sure you're using the HP if you plan to run more than about 6-7psi. With the 1.8 injectors, you're looking at about 100psi of fuel pressure to run 10-12psi... the HP can provide in excess of 130psi at the rail.

What brand/model RRFRP do you have? Is it the standard fixed-rate Vortech unit?

K-Town Powder Coating

yes I am running an external 190lphHP walbro pump because I am running a foam filled fuel cell. I do not have the RRFRP in front of me but if i remember correct it's BELL unit.

I'm glad it's the Bell unit... be sure and take it apart and check the seals... they can get old over time. You'll also want a fuel pressure gauge as part of your setup so you can really fine-tune things. Need I say wideband as well?

Keep this thread up to speed and let us know progress. Any idead on a final "look" for this thing? Paint, aero, wheels?

That's a lot of rust.

K-Town Powder Coating

I have a wideband unit I can use in it.
THe final look will be all 55% gloss black with maybe orange wheels and accent colours.

If your not sure what a locost looks like

I still want to see a locost on 15x9 6ULs.

We plan to run a set of 13x8 rims on it
