I have a stock F20C with a custom turbo kit and I'm currently sitting at 400hp.

I recently got rod knock (think I spun a bearing from having too low of oil), and I would like to use this opportunity to build my engine to reliably sustain high amounts of hp.

I would like to have 2 maps and a manual boost controller so I can very reliably daily drive at 450hp, and then be able to upload the race map and manually turn up the boost so at least semi-reliably be able to maintain 600 to 650 hp for my track days.

So my question is, what do I need to reliably be able to sustain that power?

My current plan is:

Sleeved block
BC H Beam Rods
CP Pistons
ACL Race Bearings
BC Stage 2 Cams
Supertech Valve Springs and Retainers
APR Headstuds
New Gasket Set

Do these upgrades sound sufficient?

I currently have 650cc injectors and a Walboro Fuel Pump. Will I need more fuel upgrades?

Will I need transmission or diff upgrades?

I have no experience building engines, but I am very mechanically inclined and am able to follow diy's and technical handbooks. Is this build something I can tackle myself? Or do I have to drop the money to get someone to build it for me?


There are some things I am not sure if I need or not:

New Cam Gears?
Better Intake Manifold?
New Valves?
Valve Guides?
Valve Seals?
Should I replace my oil pump?
Better Fuel Rail?
Should I get my head ported?

Sorry for so many questions, but any insight would be greatly appreciated!

 

get a stock f22c and spend your money on a strong diff then maybe a upgrade transmission. Stock s2000 engines are strong

 

I agree, with the proper tune/fuel the motor isn't the weak link at 600whp.

 

X3 on a stock motor being able to handle that power. 2 maps would be a great idea. Id suggest getting an electronic boost controller. That paired with a switch to your engine management....it can be just a flip of a switch to go from your low boost tune to your high boost tune. $100 electronic boost controller will keep things simplistic and easier to switch back and forth.


Fuel system would needed to be upgraded. Its all kind of pending the fuel you wish to use for your high boost/race tune.

 

I'd also probably check your oil more often

 

For cost of buying another used motor I would just rebuild yours to know it's a good motor just have never liked buying someone's used motors
But for that power for sure stock rebuilding would be fine but go on and upgrade springs and retainer
And like the others said trans and diff upgrades

And no on cams and intake mani they have made over 1000whp on stock stuff

Ok so the stock motor is reliable at 600hp?

I want to maintain my 9k rpm redline so I'm going to stick with an f20 over an f22. Also, I would rather spend the money to upgrade my f20 than buy a used stock f22

Are upgrades valves and retainers all you guys would reccomended upgrading for the motor? No need for any of that other stuff?

What cc injectors would be appropriate for a 600hp setup?

Also, does anyone know exactly what upgrades would be needed to the tranny and diff to reliably handle that power?

 

I think even stock valves are ok just springs and retainers. Our motors are monster on boost
What fuel do you look to run on high boost?

So all I need is springs and retainers (plus unknown diff/tranny upgrades) and I can safely turn the boost up?

I would like to run pump gas on both, but if 600 is hard to attain on pump gas then I may have the 450 map on pump and the 600 on race gas
