Dual charge
Is their Someone capable of tunning dual charge to make 900hp reliable without blowing fa built engine?

Yes. In order to make 900HP without blowing a built FA20, they swap it out for a 2JZ or an LS motor.

It depends...
Yes... there is, but it greatly depends on what type of driving you're wanting to do. If you want to 1/8 or 1/4 it, it can probably be done. If you want to track it/road course, no, it can't.
If you want to daily it, if you smoke a lot of crack you can pretend it has 900 hp. To get twin charged 900 hp out of the fa20, you would need a stand alone ECU, you would need to sleeve and closed deck the block. Probably stroke it. lower the compression and raise the boost to the moon. You aren't getting any where close to that goal on pump gas. If you have true e85, you might be able to. More like 116 race gas. How are you wanting to twin charge it? compound turbos? turbo into roots? centri into turbo? Centri into pos. disp. blower? Whatever it would be, you would need a primary charge system capable of the total hp goal's worth of air AT the boost it will run at individually... You would need a secondary capable of flowing enough air at the multiplier of the first to support that much air. Either way, unless you are one hell of a fabber and engine builder, you'd be looking at a minimum of 25-30K with no guarantees it will last more than a pass or two. Oh and don't forget about needing a drivetrain that can handle 900 hp. You can probably do it with a built TH400 and a ford 8.8 rear end, which there are adapters available for our cars for. Neither of the stock trans can handle that much power no matter what you do to them. Jaden p.s. I assumed you were serious; however, I seriously doubt you are. 650-700 whp would be a closer to attainable goal...Even though I doubted you were truly serious, I didn't want to be a prick or an asshole and make stupid comments. |

Dual charging (assuming you mean compound and not twin) in general is not very efficient for max power. Some benefits, max power not one of them. A big single turbo is where you’d get max effort power.
With that said have yet to see or hear of an FA20 making 500+whp reliably. Some on a dyno never to use that power again or maybe made a handful of runs on the strip. If you want daily pulls rowing through several gears 450whp is the most I would go on a built block and big turbo. 450whp is plenty to roast the tires 1-3rd anyways. |

Thanks for info,From what I have seen at 650-750 whp Fa 20 built is super unreliable without being granading and head gasket blown, is their a cusp of reliability for vehicles built Fa 20?
I am not sure what you mean by serious or being A hole we are exchanging info. |

That was more a comment towards the people who like to answer with non-answers.

Yeah, there's no reason that some rods and ring gap can't take the fa to a reliable 550-600. pistons, ported heads and cams should be able to do up to 750 with a closed deck block. I think the problems have more been people who are sloppy with the assembly, etc or not good enough tuning, bad fuel, combinations of all of the above. With the prevalence of swap kits for ls and 2j engines, the cost of doing an fa right for high power just isn't really worth it. Combine that with people who have had bad results with built FA's and you get the stories that everyone has heard. Jaden |

The question everyone is wondering is their a kit that can get you to that potential of 500 hp, without upgrading turbo and run under 14psi?

An engine generally doubles its power for every atmosphere or 14.5 psi. The FA20 with free flowing exhaust can get you something like 225 on race gas. So you’d need 4 atmospheres of boost, or something like 60 psi to get to 900 hp. No engines run that much boost outside of drag racing and none of those run it very long between rebuilds. Go buy a Mustang or Camaro.

If my answer sounded like a supposed non-answer, then let me clarify: you're trying to get 500-900hp out of an FA20 which already isn't known for being reliable at even 350hp. It may very well be possible to extract that much power out of an FA20 reliably, but it will take a lot of work - and therefore lots of money to do so - money that could be better spent installing a better engine (K20, 2JZ or LS), or even better, going with a car that either already has or is better suited to handle that level of power in the first place. If I may ask, why are you trying to extract that much power out of an FA20? Just curious. |

Exactly! I get it, wanting the looks of this car and the performance of a super car. But there is so much engineering needed to handle that much horsepower and be a little reliable.

Thinking you can RELIABLY make 300whp+ per liter is absurd.
Thinking the only reason it hasn’t been done, is because assembly, tune, or fuel, and that some how you will magically be the only one to crack the code is absurd. 450whp is 225whp per liter. That is already pushing it. And on a car that can easily weigh under 2700lbs that power to weight ratio puts you up against stock $200,000+ cars. 450whp when everything is done perfectly right can be pretty reliable. That’s pretty much the limit on a built FA20. You can make 500-600whp on a dyno and maybe a handful pf passes down a strip, but driving the car on the regular and actually using the power on the regular you’ll never be reliable above 450whp. |
