FA20 bolt-on horsepower gain potential - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

CSI:86 · 04-23-2013, 11:52 AM

At a local car BRZ meet in Sydney, i heard that the FA20 is more responsive to bolt ons that a K20 Honda engine. I purchased a AFE takeda intake from a BRZ owner i met at the meet. I plan to put the following mods after my friend carbon fibre wraps my car:

- Perrin Headerback exhaust
- Stage 2 FA20club tune
- Borla UEL headers

If you put the same mods on a K20, will it gain more or less power than the mods put on the FA20? And also how much power will be gained from the listed mods?

K20 vs FA20?

EDIT: Surely if the FA20 had 1k more rpm that is part of its powerband, along with a 2nd cam profile that had some sort of VVTL-i that was in the Celica. It would make much more power, perhaps even more so than the s2000.

Here in Australia, the Integra Type R are called Integra Type S. They have 164kw (220hp) stock, and can rev to 8600 rpm. I had a Jap Spec Celica that had 149kw stock (200hp) that could rev to 8400 rpm. My roommate back then in uni had a Integra Type S and he didnt have much money for mods, so he just tuned his integra. I put AEM cold air, PPE headers, Magnaflow custom catback exhaust with no cat and 2.5 inch piping, as well as tuned it with an Apexi Power FC and increased rev limiter to 9200. He still beats me every single time at the drags

I had a K24, I gained roughly 30-40 whp over stock by having, CAI, 3 piece lightweight Pulley, Hondata reflash, TB spacer, lightweight wheels, IMG gasket, Injector gasket. No exhaust mod whatsoever, I think there were a few other mods I forgot to mention.

My K24 dyno(SAE CF)

The K20 have a lot of potential(as we all know) and you can easily gain 100whp NA over stock by bolton mods, Manifolds and cam gearing + e85.

The FA20 is still fairly new, I have yet to hear anyone building or R&D'ing an Intake Manifold or cam gears for it. If you want to make the comparisons, FOR NOW we all know the K20 responds better to bolton mods than the FA20, but at this stage it is still too early to tell because the K20 has already been out for over a decade..

Wow without any exhaust mods, that is impressive!

Looks like it would be a fun themepark ride. Why so bumpy? Wish my TSX K24 felt that fast haha.

AJ PwR · 04-23-2013, 05:18 PM

I think the K20 has higher potenial. From what I have seen, with bolts on and flash the K20 easily get over 210whp on pump gas.

So far, the FA20 with bolt ons, the highest number that I am seeing is about 190whp on pump gas.

5 speed automatic transmission lol. If it was an MT, the numbers wouldve been higher.

sounds like dude was trying to sell you bro.....not even close to a k20 mod for mod. 200whp was easy in a k20. Could be though that this is just a new engine and not all the research and development is out, the k20 has been out since like 2001 i believe depending on the variation.

That's about what I put down with an afe and srt. Never tried with a header. I put down 204whp on e85 with the same mods. LOL

I've put on the AEM intake, FA20Club header, and Unichip EMS. This setup has really transformed the car. I'll be getting it dynoed next Saturday so I'll know for sure. I'd estimate about 25-30 whp.

The dude was maybe trying to sell me the AFE takeda intake. But i got a very good deal on it 250 for brand new, still sealed in the box (Here in aus, we have to pay 300 for the intake plus shipping which is about 40). After installation, the low end torque is much more, similar to my friend's 2011 wrx sti BUT the torque dip is way more noticeable

Please keep us updated. I am traveling down this route as well and wondering if headers are worth it.

Adding the headers and tune seem to be doing a great deal to take care of that dip.
