Not a jab at you, just something I think needs to be brought up when people wonder why this platform is so hard to work with. I actually agree with you, but I think a reliable 250-300whp 86 would be perfect.

Interested to see if the Cosworth heat exchanger and Jackson Racing engine oil cooler can be mounted together at the front of the car or if custom brackets will be needed?

I also stated that we must look at not only the engine, but the other components of the drivetrain (i.e clutch, transmission, driveshaft, axle, rear diff, etc) to determine how any given system can accept FI with an acceptable measure of reliability and safety. |

Here's a great discussion on compression and boost by a manufacturer some regard as well versed in FI applications!

Exactly. Don't forget the economics of trade and raw material costs. That's why the only response to these people is you and your parents effed up the world and now we can't have nice things. Thanks a lot, now go piss off.

However the person you're quoting simply mis-read or mis-interpreted my point that the FA20 engine, as it sits, is not suited well for boost since it is high compression of 12.5:1 (being N/A, this is typical). That has little to nothing to do with emissions and regulations |

People sell their FI projects for many reasons: 1. They thought it would be faster than what they actually got 2. They thought it would totally transform the car 3. They got bored with it because it is still a cheap sports car 4. They got bored with it because after the FI kit the project has reached its climax 5. They were disappointed in the initial product and thought spending 5 grand on a FI kit would satisfy them enough when in actuality that money would have been better spent on a new car that actually satisfies them 6. They just want a new/better car I have never experienced anyone saying they are selling their car after putting a FI kit on because they think the motor wont last. Those people that fear the motor blowing would just take the FI kit off or not put it on in the first place.

@mkivsoopra 's and my turbo motors running at 6-7 psi (275 whp) hard at the tracks here are running strong. @CSG Mike 's JRSC'd motor has been pushed harder than anyone's FI setup. @ImperiousRex 's turbo motor has been pushed hard through time attack competitions and is holding up great. All of these people understand the concept of knock and how it destroys engines and so they run the appropriate tunes, psi levels and fuel octane to keep things safe for high performance duty. For a street car on pump gas you need to keep expectations realistic of what the motor, with low octane, can do. If you just need to run 30 psi of boost and make 300+ whp on 91 octane safely then look elsewhere for a low CR motor.

That being said, we haven't run into the limitations of 12.5:1 compression yet, so we won't be dropping in our lower compression engine until we do. |

Im wondering if that same philosophy and application would work here as well.

Well yes, although I don't know enough about the F2xC to know why it would have caused problems. it was a stupidly low cost way to psudo change the CR. in any case, I'm just holding out the funds to swap Pistons and the works.
