Specs from both Godspeed and SpeedyRacer gt28 are the same, on paper. I wonder if they're both physically the same measurements as well.

Default spool up rates! my first post here!

hi my name is pete
the turbo scene is nothing new to me
ive been turbocharging or trying to at least since i was 15

first reliable turbo car was my 96 civic hatch at age 19

im a member at home made turbo.com

im glad to be here

ive just finished building a set up on a friends car. my first turbo miata project! here is some specs. ill post pics soon!



Engine: '91 1.6L
Turbo: T25 .48/.49 AR
Manifold: ebay obx ss 4-1
Downpipe Size/Style: Single tube 2.5"
Exhaust Size: 2.25"
Exhaust Components:1 cherry bomb
Intercooler Core Size: 25x2.5x6.5
Intake Manifold: Stock
boost level 6psi
ignition timing 5* btdc

Engine Management: junkyard turbo-mx6/ford probe fuel pump + 12:1 fmu

tire size: 195/60/14



spools extremely fast makes 5-6 pounds at part throttle before 3k in 2nd gear full throttle spools a bit quicker

car still needs more fuel im running 5 deg btc timming at base and still runs a little lean so im waiting on a walbro 255 HP (high pressure) fuel pump so i can have enough fuel to turn up the boost.
