sorry bit of threadjacking 😆 Kyle, how do they compare to the GT42R BB powerwise and in spooling? have heard great things about the GTX and tossing up whether to go twin GTX or twin PT76 on my modular.
BLN355 do u log the backpressure? would be interesting to see if there is a big difference, i’d imagine the bigger rear housing would have less backpressure.
Same spool, more power than plain GT42. Precision seems to have their shit together with their new billet stuff as well, have seen their 70mm go over 900awhp on a GTR, I think it is much of a muchness between the 2, I just like the garrett stuff.
half in head studs o-ringed block and copper gaskets will keep the heads on Whatever block filler you use it should be done with tourqe plates bolted on the block regardless what you do the tune will make or break it doesnt matter how good the parts are or how well the engine is built with a dud tune any engine will let go
