Break in the 2.5L inlinepro engine
#101
In case that I blow the engine, today I heard a blown S2000 and my does not sound as bad as his, which parts do I need to order:
1 - Headgasket
2 - Rings
3- What else?
On monday will tow the car to Honda to see what is wrong.

I think what you need to order is more based on what blew the engine.
If it is scoring on the walls, it'll need to be honed if it can be. I thought the F blocks couldn't be honed though.

the F block can be honed with the right tool
S2keurope 's block is no longer the standard FRM block
What you need will depends on the cause of this noise. Worst scenario is piston slap. I hope that the crank bearing caps are still ok. You will need to rebore and hone the block. New pistons, rings and head gasket.
You should change your oil and filter now.
Good luck Juan.

^ do you mean rebore?
If that's the case don't drive the car any further until the cause is known. The less damage, if it is piston slap, the less you have to take off with rebore.

Juan,
I cant imagine what could be wrong with you motor if the A/F was always good. If it went to far past 14 that might be the cause. we run mine really rich for a NA motor.
Your motor should be sleeved like mine i popped the first one on the dyno then we overbored it to 89.5mm originally it was 89mm. So if something bad happend you have room to grow.I hope this isnt the case, my motor i noisy sometimes hopefully thats all it is. but i would have it checked out.
Best of Luck,

Just wondering if the fc20 has some similar oil cooler. I have too few miles to really get aquainted with the engine.

Here I have the dynos
This is a NA, 15.000 km, with HKS Exhasut, DC Header and 4.44 final ratio 214 Hp and 133 lb/ft; friends has made 240 hp with an HKS EX with 60.000 kms.
This is a Comptech SC and Aftercooler, 30.000 km, with Comptech Exhasut, Toda Header and 4.44 final ratio 321 HP and 195 lb/ft;
This is a Stroker kit, 2.000 km, with Amuse Dual Exhasut, Toda Header and 4.56 final ratio 252 hp and 195 lb/ft;
All these numers are at the crank not Wheels and are CDI number not SAE ( I do now what the hell that means)
I got same torque than the SC but a lot less HP; I have been told that the engine can't flow more air inside the head, maybe we are limited by the cams?
