I replaced the bypass valve with the new style one on install - I'll check it tonight though, good call. It does look like the crazy LTFT only starts around mid-throttle around 2.5k.

Edit: just checked - held it at -10 in/hg for a few minutes with a vacuum gauge and it's rock solid.

I'm wondering if I bungled the intake mani gaskets, but that should show up on an intake manifold smoke test right?

edit: probably the dumbest question ever - I have the dual radium catch cans with my edelbrock setup - are you guys running the stock PCV also? I'm running lines directly from the catch can from the breather port -> can, and the other hose goes to the intake manifold directly. Also wondering if this is causing the weird issues im having.

edit 2: nvm, just realized the pcv is on the block. there is a bit of oil seepage, but I'm assuming that's normal.

Finally finished installing my Edelbrock and had it tuned. Gained over 120WHP from stock, VERY happy with the results, totally worth it.

The tuner kept the torque lower so I wouldn't snap any connecting rods.

Tuning day at PerryTuned in Tiverton RI

I have/had similar issues. Have you checked your port injectors? Try cleaning them they may be clogged if you're at a higher mileage like mine were.

Good call - I'm at 85k now, I'll send em out for cleaning.

edit: Just had em cleaned - they tested perfectly. Injector guy is just putting it all back together now.

edit 2: anyone had to clean their direct injectors before? I'm wondering if that's the issue (or the seals going out)

Nice, any other mods? headers or exhausts etc?

Yeah, HKS catless headers, overpipe and Corsa exhaust. I'm keeping the stock catted midpipe as I got all the power I think the stock motor can safely make.

How difficult is changing injectors once the SC is in place?

Also, who all is tuned over 400whp+ on the E-force?

I've seen countless stock internal sub 300 builds, and a handful of 300-350 tunes, but I think I've only seen 2 documented tunes of over 400 or even close to that. I'd love to get some more information on some of the builds around this power level.

Very easy (port injectors anyway) Literally 4 bolts + a couple for the black metal ecu bracket on the passenger side.

Just pulled mine to test, took less than 30 min.

It takes a built engine, which is why it's rare. Furthermore, the stock trans is a ticking time bomb at that power level, so you'd want to have a spare on hand, or build/swap the trans as well.

You can take some measures to keep the torque down to make things last longer, but it won't be forever.

What’s involved in building an FA20? I understand the rods are strong as ramen. I don’t think I’ve seen this platform get sleeves.

It get's even easier on the passenger side if you get a new injector controller bracket. Everything on mine is exposed, and super easy to get to (also, I think it looks way better under the hood with the new bracket)

Therein lies the problem. Everyone tries to "only do what they need" aka what they think is the bare minimum (typically rods and pistons), blow up, and then abandon the project.

They forget everything else. Heads, machining, studs, cooling, transmission, etc.

Talk to engine builders who have experience with Subaru engines and they'll tell you how much more they love the EJ engines. The FA20 engine is more complicated with more parts, more screws, more gaskets and sealant. The FA20 engine is 55kg heavier compared to an EJ20 engine, which is an indicator of the increased complexity. Not an issue for the factory to assemble it with all the modern automation, but a more serious problem to hand assemble it with higher points of failure ...

dpfarr · 10-21-2021, 06:02 PM

Looked up some articles about creating solid fa20 fi platforms.

Seems like keeping it well under power threshold, our cars can be wringed out without issue. Divorcing the more more more theory from car modifying is something I haven’t suffered from greatly. I’ve always preferred the solidifying approach that I can do whatever all the way to the limit of the car and still drive the next day. Going to have to keep this not so deep in the back of my mind.
