Morning bros
I have some Troubles with my engine which swapped into Mazda RX5 f or drift use
I've just installed a gt 28 ( ball-bearing) turbo to my b230fk
1 - i used 1 mm external oil restrictor (the turbo has 1.5 mm. Internal. One but bearings' sound is better and more calm with the external. Restrictor..
**tell me if i need to change or modify the external one)
2 - boost gauge shows - ve and when I reach high rpm. Boost gauge get closer to 0 in - ve range as well like - 0.5...-1 etc.
3- when gears on natural it reaches rev Limiter as usual it not when loaded with full throttle it holds 4.5 rpm and still dont rev higher or even dies !
* fuel pressure 3.7 bar *
*i've tried to remove wastegate vaccum but no change happened neither boost nor rpm*
*maf working as engine's sound and response changes when i connect or disconnect it *
Thanks for your efforts
