A properly built engine from the looks of it, wouldn't cheap out of the exhaust manifold on a build like that tho.
Nice build going on there looks very similar to mine, unsure of what turbo i have but its a similar size. Although i would try and do something to support the manifold as mine cracked a few month after i bought the car, probly down to the weight of th turbo. But its fixed and been alright for about a year now Nd no other problems, and really pulls! I think this will turn out good good luck with the build.
That manifold is going to crack the first time it see's boost. Those look like 444 injectors, what have you got those for with such a monster build?
love thid build im doing sumthing sim but ive got the same injectors but ive been told they dnt fit my ca18 is this ryt or rong
