Stock FA20 block - Force Induction - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

RG4L · 06-17-2020, 01:34 PM

Hey guys, im new at the car scene and just wanted to be more mindful about what to expect if I turbocharge my fa20.

Its currently stock, of course I will upgrade internals and fuel system. My top top goal would be reaching 450-500 HP Now some people say a turbo kit could do it after upgrading the rods and trannies, but my main focus right now is getting force induction.

What turbo kit do y’all recommend that in about half a year I could push my desired HP (After the upgrades)?

Will the stock FA20 block hold this much HP? Or would I need a built forged engine?

Also would appreciate some does and don’ts

You won't be able to buy a kit that will be safe today and make your goals next year.
Get the JDL turbo kit with a T3 manifold. This way at least you have a great reliable base platform, and the T3 sizes manifold will accommodate a turbo upgrade in the future that would meet your goals.

I promise that you will not get 500WHP to last more than a few dyno pulls unless you put another $20,000 into the car on top of the turbo kit. SOmething more civil like 350WHP would be easily doable with the JDL kit. Hell, you could do that with stock block and maybe be ok for some time.

So lets say Im planning on buying one of does crawford built FA20’s that do 500hp, would I be okay using the JDL kit now and then switching the block and putting the kit back on? Is that like a thing?

These are discussed to infinity and beyond here. For 450-500 HP, don't waste your time and money with this car.

RG4L · 06-17-2020, 03:29 PM

So go all out or nothing... ��

Buy some extra transmissions or be prepared to convert to a CD09.

RG4L · 06-17-2020, 03:46 PM

Damn thats a cheaper option than buying a built FA20, was it a joke or a real option?
Lol

You can easily do 400-500whp reliably with a transmission that doesn't explode 4th gear for $15k in this car keeping the FA20. All the info is here if you research it.

Easily and reliably to 450-500 whp. Sounds like you have done that. What was your cost?

The trick is to make 500whp on a dyno on one pull, and then never go over 10% throttle again. Then you can claim 500whp with 50k+ miles reliably no problem.

Goingnowherefast · 06-17-2020, 08:01 PM

I'd just get a fast car instead.

Like mentioned, to make 500 whp reliably (god forbid you try to track it reliably) will cost a LOT of money.

A fully built FA20 with a turbo on E85 and a CD009 trans swap should be pretty reliable at 400-430whp as a daily driver / hwy puller / canyon carver, but even with every supporting mod possible i would still turn it down to about 350-380whp for the track/autox, and even then its risky.

The built FA20, turbo, and trans swap could be done for maybe 15k$ if you use your block for the core get it built, and do all the installs and trans swap yourself. but you will still need driveshaft, and axles if you don't want to break your stock ones, and tires/wheels to actually put the power down. You'll probably want oil cooler, catch cans, and hood vents at minimum as well at that power level and with the heat from a turbo making 400+whp. It can add up to 25k$+ real quick.
