Here it goes, THE NUMBER 1 REASON the fa20 blows up under F/I is THE RODS SUCK they are nothing more than TIME BOMBS under the STRESSES that F/I PUTS OUT!!!!!!!!! PERIOD the END!!!!! Will the rods hold up to 8000 to 8500RPM N/A sure they will no problem oil will be the issue then at that RPM if it stays at that rpm for while. So to drive this point home their is no real way for anyone to claim a certain psi is safe. NO WAY!!!!! A gt45 at 18 psi and a GT28 at 18 psi are completely different. And the stress that goes with the bigger turbo are harder on a stock engine.. Sure you have companies out there telling you its all good no worries go for it but they sell products its there job to sell. I don't know of any company that will replace your engine if it pops and that should tell you something... I personally know guys pushing 500 whp on stock motors for close to 2 yrs with no problems. I also have friends that popped around 325 to 350 hp.. Its a roll of the dice.....
Which leads me to the next point. Please please please for the love of whatever you love, stop blaming the tunes....If a rod went its most likely not the tune if you have a huge hole in your piston it could be the tune but it could also be mechanical. Faulty fueling like a bad pump bad injectors. Please find the source before placing blame it's the right thing to do. Their are some really great people on this forum that have years of experience with this craft and have tremendous knowledge about this platform that are more than willing to help you. Most of them for free... Just ask..... So is it safe to boost a stock engine well that depends on what you call safe. Can it be done at a low psi and live for awhile? sure it can but don't' expect it to go 200k and not have a problem.... My thought are this if I bought a new frs/brz the first thing I would do is boost it to 300hp for everyday driving. That's my personal feeling of remotely safe and a risk I would take to have a car that feels amazing to drive... Anything above 300hp I would replace the rods and pistons. Just be aware that the 6k you invest in your boosted fa20 and what the truth is behind F/I
One more quick thing don't get caught up in the numbers game, 30psi or 650hp. Do what feels good to you and stop, numbers are for bragging smiles are where its at. If you get a big cheesy grin at 300hp that's all you need and your car will last a lot longer.. Trust me 640 hp on the street isn't much fun so I just dial my boost down and cruise along. I only run wastegate springs set at 5 psi on the street that's all I need. I hope this helps some of you new F/I guys. Peace and let the flaming begin lol
