FA 20 block power limit - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Nigelr32 · 04-27-2017, 03:40 PM

Hi everyone, Nige here from the UK..

I have been looking around on the net for an answer to my query, but haven't got a definitive answer yet.. thought maybe someone here could help??

As some of you will know I'm building a track car and am going to turbocharge it. I have a GTX3071R but am being led down the path of getting something bigger, like a 3576 or 3582.

So, my question is this.. what is the highest power levels tested on a stock Block. Not Pistons rods or crank, but the block. I believe the weak point is the open deck design, am I right.. is this where they fail?

I reckon a 3576 will give 600hp.

I think Gushi from FD still uses the stock block and has like 650hp or so. Upgraded internals of course.

While I have no first hand experience with this I know that typically on EJ motors when going for very high power they would go to a closed deck and sleeved setup. Not sure if this applys to the FA20 as much or at what point it would be needed.

They tried to built the FA20 but had trouble keeping it reliable and scrapped it after the first year IIRC.

As far as your question goes. I think theres a few guys pushing 600+ on the stock block reliably.

Thanks for the replies guys. Didn't Gushi run an EJ initially?
Beau Yates in Aus used the FA20 for a year then changed to 2J.

The Vsport Aus car runs a built FA, but is nowhere near 500hp.

So, do we think 600hp is safe on the stock open deck? I have read that the EJ is made of monkey metal, whereas the FA is better quality?

Local guy here has 500HP reliably on completely stock block

At first yea he used a flat 4. I don't remember if it was a fa20 or not. I thought it was an EJ they dropped in.

The '17 manual only blocks have been strengthened compared to previous years.

I have read and seen guys on stock internals supercharged e85 running around 380hp to wheel. So 450 ish to the crank. Can our driveshafts handle 600+? I thought they would blow from the force.

I have uprated shafts, hubs and a Samsonas Sequential 'box, so drivetrain strength isn't an issue.

I'm not talking stock internals here, I am asking about the strength of the block. TBH I wouldn't put any more power through the stock internals, but then, I build my own engines.
