You need to figure out what you want to do with the car and talk to your tuner. If you want to know what the block is capable of in stock form, then try searching. That block has been around forever so whatever you want to has probably been done.

I’m prepared to be told to just search, but it seems appropriate to ask the question in this thread. Can I reliably make ~300whp on a FA20DIT with a stock turbo, stock engine? Pump gas, no ethanol. Im starting to make long term plans and my power goals aren’t gonna be too crazy (I used to drive a Miata, the stock car feels like a top fuel dragster in a straight line).

Dyno Numbers and you- What do you need to hit XXX hp?
I’d like to know what it would take to make 300+whp without extreme price or a fmic on an otherwise stock 06 WRX sedan, i’m from Brooklyn, so pretty low altitude, and i’m not entirely opposed to running E85/flex, particularly considering the much lower price right now, but i’ll probably be running 91 otherwise. Obviously without E85 it’s a large request, but i’ll definitely be doing work on it either way, whether it’s a cobb s2 kit or custom parts, so I figured i’d ask.
If it can be done on stock turbo + engine and/or pump gas that’d be huge. |

Generally a 16g or 18g sized turbo will get you there. Need larger injectors, fuel pump, down pipe, and quality tune. A better TMIC will help but it's not required. |

If you go flex noticeable gains can be made over this, but then it's new injectors and a flex fuel setup besides -- probably 3x the cost of the aforementioned setup at least. And now your tranny becomes at risk as well. |

Hey guys, I'm planning out my build list right now for my 2021 WRX. I'm only at 175 miles, so I have a hot minute to go before I start adding anything on, but I'm gathering my build list now, so that I can be ready to start modding and getting tuned once I'm well clear of the break in. I'll start with my goals for the car, then include the list of what I'm looking at to get me there. This list is only for engine mods, not going to include all the susp/brakes/etc. I'll do the mods myself for the most part, as I have access to shop space and do this type of stuff on my truck already.
Location: San Diego, CA. (Sea Level) Tuner/Shop: (unknown for now) Goal WHP: 300+ Planned mods (in roughly this order): 1. Accessport V3 (MAPerformance OTS tune to start) 2. Grimmspeed (GS) catted J-pipe 3. Invidia r400 catback exhaust (open to other options though) 4. Cobb CAI 5. BPV (boomba primary, open to others. not doing BOV). 6. FMIC (GS or Perrin, open to others as well) 7. GS EBCS 8. Protune (likely do 7 & 8 together) Let me know what you think is realistic for these mods. I'll likely do 1-5 all at once since I'll need to be under the car anyways and removing the skid plates and bumpers once would be ideal with regard to efficiency. |

1) AP 2) Flex fuel kit & tune 2) ?? 3) Profit (goal achieved) Otherwise, yours sounds achievable with non-CA gas. I don't know how bad it is but those are the numbers my wife and our friends are pushing with very similar mods. |

R400 with the J was a bit loud for my liking FYI. Not for around town but I am on the highway alot and I grew to occasionally loathe it. Ended up switching to a Q300 before Mother Nature took her out. |

I haven't looked much into FF in my area. I'll have to dig into it some more before I commit to any mods for sure. Thanks for the input! Quote:
Nice, I'm glad my list resembles someone else's. That is some good beta on the exhaust in the long term. Is the big difference between the r400 and Q300 just the muffler size? was it all the same tubing to the rear axle split? |

Just the muffler size. Same mid-pipe and y-pipe. To get the mufflers on the front hangers you will have to remove the rear splash trays from each side though. I think. I'm not a pro just someone who found out the hard way doing a "20 minute" swap lol.

Any thoughts on a ~450whp on 91 + 50/50 Meth Turbo on a mustang dyno?
Car is a fully built EJ257 with AVCS, S2 cams, rotated turbo setup. Has a GT3076R on it with a .82AR housing currently. Killer B Holy header, rotated up pipe, 1k cc injectors, FMIC Will likely NEVER see e85. Have access to 99 AKI though. New turbo ideally has a T3 inlet and 3" Vband outlet. Should I just get a GTX3076R gen 2 supercore and call it a day? Was thinking maybe a G30-660 |

Killer B and several others have found the 3576 performs better without any real world drawbacks compared to the 3076. It will also get you to the goal with less effort and therefore be more efficient at your intended power level. In my research, I've found it hard to justify the G-series over the GTX gen2. They seem to perform very close to each other on the EJ platform. On other engines the G-series does better. There are a couple 2.35 builds I've been following which seem to have done well with the G-series turbos. However, there's no back to back comparison to see if the GTX options would've done as well. You may need larger injectors most likely to get to that power. |

GTX3576 Gen 2 is the best Garrett turbo for 2.5L for 450+WHP. Spools close to stock but makes heaps of power. And the turbine and compressor wheel are well matched to eachother unlike the 3076 imo. |

I’ve heard 330-350tq is the max you should run on a stock fa20. Is that number at the wheels or the crank?
Thanks |

I'm on deployment right now and drooling over the parts I have sitting at home right now, so I'm curious if anyone has a good idea of what I'll end up making.
Right now on the mustang dyno at All Aspects Motorsports in VA, I'm making 273 WHP and 280 WTQ. My goal is around 330 WHP and torque, but I'm sure the actual number will be different to keep my engine from chucking a rod or two. Info to follow 2019 WRX, FA20 with stock internals, block, and turbo Cobb catted, non resonated J-pipe Greddy RS Race cat-back Cobb Big sf intake Perrin BPV TGV/EGR Delete (Will probably have to reinstall prior to getting tuned thanks to the Greenspeed update) Grimmspeed 3-port BCS Boomba CCV Catch can. That's my current setup, mods to be added before the next tune are: Grimmspeed TMIC w/ thermal Dispersant coating DeatchWerks DW300c LPFP Perrin headers Grimmspeed's aluminum turbo inlet Grimmspeed's chargepipe SnowPerformance water/methanol Kit (I believe, AAM said that they install a 2.5 gallon tank in the trunk and that's the only kit I've seen with that exact size, and I haven't been able to get a quote quite yet since this all won't be done 'til October) I was originally going to go flex, even bought the kit, but then greenspeed happened and AAM suggested methanol as they had been the whole time, shoulda listened to 'em from the start haha. Any insight would be much appreciated, It's been months sine I've been home and all I can do is think about how much fun this is going to be! Last edited by Surfingcricket; 06-28-2022 at 04:58 PM.

Changed the direction I was going cars-wise, got a 2008 spec.B legacy with the ej255. Motor has already been rebuilt so here's the current mod list. I wanna see what I need to make 400whp on 93, but either way more realistic numbers work too. i know a fuel pump and some other stuff is definitely in order though.
main stuff: ID1000cc injectors, VF39 Turbo *MAKING APPX 23PSI IN S#*, COBB SF intake, grimmspeed 3 port EBCS, IAG AOS, FMIC, exhaust is an Invidia catted downpipe to Borla mufflers engine was rebuilt appx 10k miles ago after ringland failure with Heads rebuilt by HeadGames Motorworks, Supertech (Mahle) 4032 Forged pistons, ARP Headstuds, ACL Race rod/main bearings Last edited by virtus; 08-27-2022 at 01:40 AM. |
