  • Actually, it's not wrong, dumb ass.

    Get your facts straight. How does a V8 look bad inside of a S13/14/15, inside of a Miata, one of these ^.

  • @ManRossDamn what do you mean the devil z? the original true devil z is part of an anime called wangan midnight and its a s30 with a l31ett and that guy was right he should have put an rb26 into it. keep it the same manufacturer. i respect the car for what it is but to ppl like me who love z's for what they are putting another car manufacturers engine into one is just wrong.

  • @colorgard Ever heard of the Devil Z?

    Way to be a ignorant goon, appreciate what people create.

  • Ruined a z with a 2j wtf shoulda went rb26 but still sounds good

  • I not sure what you mean. The smaller turbo will keep spinning and making 20PSI the whole time. Because it controls the wastegate, as soon as the boost in it drops (ie, because engine revs dropped) it will close the wastegate to maintain boost, and the larger one will spin down.

  • @ThelenShar

    so one could blow air backwards through the other if the lower boosting turbo was going slowly?

  • @tpvalley that is correct. but by then so much gas is flowing, it will spool up VERY fast. this isn't anything like what BMW have. intake wise, you can clearly see they both suck straight from the air.

  • @ThelenShar

    the problem with that is that the large turbo will hardly spool up until other gate opens?, on the bmw model both turbos have their turbines fed from manifold in paralel not series and valves for air side.

    what about the inlet side do they blow through the small one?

  • @tpvalley when the small turbo reaches 20 PSI, its wastegate opens, and EXTRA gasses flow to the larger. the smaller one will continue to make 20PSI (well, minus small drop) the whole time

  • how are the gasses routed?

    does one feed the other? if so, doesnt one restrict the other or does the smaller turbo wastegate open at the same time as other turbo spols up?

    what about exhaust gasses? have u any valving other than wastegate and dump like the bmw setup?
