at the moment the turbo i have is a unknown i cant find any specs on it anywhere but(insert laughter here) ive found 1 guy thats fitted the same turbo onto a 1.6l honda civic this tells me that its WAAAAAAY too small
im runnning a top of 8psi but ive ran a max of 18psi for a laugh
im going to fit a r33 skyline turbo onto it 2.5l that revs to 7000+rpm so should be nice for a 4.23l that revs to 4000ish
its a totally new vehicle to drive no more downshifting for the hills just give it some gass and you keep going just last week i did a 650km return trip down some roads i used to drive and 1 section is quite hilly id often be in 3rd doing 60kmh but with the turbo 5th gear 100kmh all the way
also fuel consumption has not changed at all within 10km a tank
