What does this exactly mean?

I am interested in getting turbo in the future from InLinePro. If the S2000 has forged internals, how much money have I already saved for a turbo application?

Also, do other sports cars have this done to their internals or is the S2000 one of the few that has this stock?

Please advise

thanks

 

Also how much boost can the forged internals handle for a 2001 S2000?

thanks

 

forged is how they're made

cast vs forged:

cast is poured into a mould

forged is basically heated and beat into a shape

there is lots of info in the F/I forum as you've surely found. Car's don't have this done to their internals, but rather either come like it ('07 sti, and a few others) or you can sometimes buy replacement "forged" internals

it's certainly stronger, there is info on how much the f20c block can hold with boost


no offense, but you have a lot of reading/learning to do, but it's a good place to get started

GL and enjoy the drive

 

you haven't "saved" any money because forged internals aren't a requirement for forced induction, they are just stronger than cast. Forged internals for a car without them would just be an available upgrade.

 

I would say he has saved money in the long run, especially if you are looking at ~400whp @ ~1 bar of boost.

Sure you can boost your car on stock internals, but its risky, and usually you end up loosing. Again, if you're only looking for "pump gas" power, a 3mm head gasket is WAY cheaper than rods, pistons, and sleeving your block.

All this is to say that since the S2000 has forged internals already, with a 3mm head gasket you will make 400whp safely on pump gas as opposed to say an Integra type R who has to replace his stock rods and pistons with forged counterparts to safely make the same 400whp on pump gas.

Why do you need the head gasket then? To lower your compression. In general, Honda guys will replace their pistons will low compression pistons...in order to safely apply more boost to their application.

The catch is that the S2000 has high compression pistons, even tho they are forged. So you are limited in the amount of boost you can run before detonation becomes a problem.

I would suggest to search around honda-tech and get a general grasp of what all these terms mean. That where i learned to build my 450whp honda before i sold it.
This forums search function is somthing to be desired. Im not knocking it, just trying to help the guy out. So whatever you cant find in the stickies, search the honda tech archives.

 

Why did you sell the beast?

 

Forged > Cast. Thats all you need to know. If the S2000 had cast pistons/rods you wouldnt see people making 450whp on the stock internals, or if they did it wouldnt last long. The F20/F22C is a very strong engine. Since these engines see lots of rpms honda saw fit to strengthen the rods and pistons to make the chance of failure lower, and it has worked since you hardly ever read of a F20/F22 just blowing up.

 

An important note is that despite being forged, the factory pistons and rings are geared toward naturally aspirated use. The compression is high (which can be mitigated with a thicker head gasket) however, more importantly, the ring lands and rings are relatively thin compared to aftermarket forced induction pistons.

The thin ring lands especially make the piston more apt to cracking from detonation. The safety envelope is smaller using these pistons - so careful conservative tuning is even more important when retaining the factory pistons.

Forged Steel is not only stronger than cast, it also dissipates heat much better.

 

Man, i'm learning new things about the S2000 that I never knew. No wonder a lot of people are going turbo in the S2000.

This is great information. I am definitely going turbo soon........

In my eyes, the S2000 straight from the lot is one of the best sports cars that came out in the 2000's. Classic.
