пообщался с англичанами на счет чипа... пришел ответ
hello eugene,

i dont offer a turbo chip for the m20b27 specifically but i do offer a turbo chip for the m20b25 which has been used by a few customers with 2.7 strokers (b27 engine like yours but with the 885 m20b25 cylinder head). if you were to install an 885 head on your m20b27 and you had a motronic 1.3 ECU then you could run one of my turbo chips. the chip is tuned for 8psi of boost with 30lb (310-320cc) fuel injectors. unlike most other turbo chips the off boost areas are not left like standard. i have spent alot of time tuning M20's (m20b25 in particular) and therefor i have put all of what i know into the off boost areas so that performance is great on or off boost and if you drive the car easy you may even see slightly better fuel consumption than when the engine was standard. вот эту часть не понял)) английский не сильно развит))) подскажет может кто?)))

can you tell me what ECU is in the car at present?

8 pci это всего 0.55 бара, не маловато будет?))
короче надо ставить 885ую голову... вот что делать с поршнями? сток или от 2.5 ???
