just got my first miata,its a 1990 with a full diy turbo setup. it is running 5 psi now but will be upped as soon as i buy bigger injectors. we built a few supercharged jackson racing miatas at my work way back in the day and i always wanted one just never got to it till now. the full diy one page answers really helped me figure out where i am gonna go with this.

 

Pictures please. And a parts list. Did you do the work yourself?

 

What sort of engine management are you running? Welcome to the board.

 

i will put up pics/parts list right away. no i got the car off a guy in vancouver that built it.
i did a search on injectors and they are stock and it is running 5 lbs boost right now,but will be ordering b2600 injectors right away and working on upping the boost.

 

Welcome, and x3 on parts list/pictures also what did the guy tune it with?

 

Welcome, pics.

5 psi and stock injectors - I'm thinking an FMU.

 

Ah okay, I forgot about it having stock injectors.

 

yes its an fmu for tune, its a vortech i will take pics today as it was -26 here yesterday.

 

Yikes -26, I thought it sucked where I lived being 30-40, but wind chill makes it about 20.

 

 

and my wonderful 10 hour trip home out of 3 towns and 19 gas stations none had air,and forgot my tools/spare/compressor/jack/ had a great time dealing with it

 

exhaust manifold is a bentek? if i remember right from looking early this morning
vortech fmu.
msd boost control box
t28???? turbo someone might be able to look at pics and tell me
rx7 turbo intercooler(assuming off a 91 or so turbo2)
stock injectors(cleaned and flowed when turbo built
not sure of bov brand looks chinese could be wrong
mbc run off the intake
custom built downpipe into stock exhaust(was in vancouver so had to pass aircare)and it will be 2.5" or 3" soon
equus boost gauge had egt before ???? not sure if i will put one back in
and not sure if it is running wideband o2

now i am probably gonna get ripped on but the search only part helps me and i know every case is different i just need someone to give me a rough idea besides injectors what else i will have to add/tune/build to run say 10 psi
it is currently running at 5 psi

 

looks like a hacked up greddy kit. don't think its a t28.
you need engine management as the 1st and most important step towards 10+psi

 

ok that helps. what is the best route to go as far as engine management? and hope someone can tell what the turbo is then? i will get the numbers off it tomorrow at some point and throw them on here

 

That is definitely the turbo kit, right down to the wastegate and oil feed system. It's a 14b mitsubishi turbo. And as far as engine management, go Megasquirt or AEM EMS.

 

have seen a few hate threads on flat white on a miata but no pics so i did mine flat white over the last week. i will post pics asap(the only ones i have is on my phone so i will run out to the shop in the next day or two and take some pics.

 

couple bad pics off my phone

Probably need a new clutch in that old bitch to run 10psi.

 

has a new clutch(stock but new) and will not be rockin 10 psi for a while.
