So true. I had no interest in that car until I saw this number. But I think the price will be so high that I won't be able to afford one.

Very impressive track time. you had my curiosity, but now you have my interest.

@tahdizzle lol ... Fail. Nice try though.

I'll look for some real dynos later, just for you mate.

I've seen the 2006 civic si hit 240 WHP with;
- 3.5" intake
- 3" header-back exhaust
- cam upgrade
- intake manifold upgrade
- Flashpro

At this point , they can raise their rev limit to nearly 10k too which is pretty dam cool if you ask me



Here we see a pretty conservative build using the mods i listed above. With e85 @ a better tuner he could hit 250WHP on a N/A 2Liter

Yup, around 280-300bhp is not too hard to achieve with a K20 says the K swap MR2 and Lotus people. Amazing engines, and they come with pretty strong 6 speed gearboxes too at a pretty low total weight. Why isn't Honda making a RWD car again? Practicality and cost be damned (okay up to a certain point), I would immediately put down money for a new Honda powered MR car.

Would sell my 86 right away if honda made a new S-Class car. Honda always blows away the competition.

Fixed. Unfortunately

[Sideways&Smiling]

Honda needs to make that mid-engine turbo baby NSX/S2000 successor coupe they've been talking about. That would literally be my ideal car. A 4 cylinder turbo mid-engine lightweight car with double wishbones all around.... basically a baby version of an NSX/Cayman GT4.

Here we see a pretty conservative build using the mods i listed above. With e85 @ a better tuner he could hit 250WHP on a N/A 2Liter

Engine: K20Z3
Intake: Stock with K&N Filter
Exhaust: Kidd Racing Dominator Header, Go Power Motorsports Exhaust
Valvetrain: Brian Crower
Bottom end: Stock
Engine management system: Hondata Flashpro
Other engine and drivetrain mods: Brian Crower Stage 2 Cams
Track info: None
Dyno Type: Dyna Pack


This is the info on the mods to go with that tune.....

Valvetrain, and Cams I guess are "Bolt-Ons" since you technically only have to remove some bolts.

***Updated 7/26/09***
Engine:K20Z3
Intake: T1R CF Intake
Exhaust: KiddRacing Header + test pipe + GReddy Spectrum Elite 60mm exhaust
Valvetrain: Toruku Street Cams, Stock Valvetrain
Bottom end: Stock
Engine management system: Hondata FlashPro
Fuel system: Stock
Other engine and drivetrain mods: P2R throttle body spacer + gaskets, Boomba Racing Motor Mounts
Track info: N/A

Here is another Civic Si w/ pretty much the same mods and a tune. But the one you posted is "Conservative".

[tahdizzle]

Anyways. The point being that parts are still being developed for the fa20.

We have I/H/E and an e85 tune pretty much for bolt-on power.

Then we have trolls chime in with k20s make 240whp with just bolt ons and a tune. The fa20 is garbage. All hail honda!

Yes. I/H/E, Cams, Valvetrain upgrade, and a Tune. Yup, a k20 makes godly power compared to a fa20 with I/H/E and e85 tune.


08 Civic Si (K20z3): Bolt On's - Pump Gas Dyno Tune
This car belongs to Matt from Gaffney. This is actually his wife's DD.

Setup:
Skunk 2 Header
Buddy Club Exhaust
Injen Cold Air Intake

Otherwise, the car was stock.

Tuned on Hondata Flashpro

Here is the chart:

The blue line is the base run, with the stock ECU, and the green line is the tuned map.



Most of the gain cam from vtec engagement in addition to the typical fuel and ignition tuning. We also adjusted the cam angles under light-medium load to reduce lag. Stock cam angle dropped from 40 degrees to around 15 degrees every time he went to shift and returned to 40 degrees as soon as the clutch engaged. Since the cam sprocket is hydraulically controlled, it actually takes the sprocket .1-.15 seconds for every 10 degrees of cam angle change. As a result the customer would experience of lag of about .35 seconds every time he shifted. We adjusted the cam angle so that it would stay the same for the medium and high load areas of the map to eliminate this lag. Again, this is not really noticed by most people but does make a difference, especially in forced induction applications or higher HP setups (domestics included).

here is a build that is closer to what we have available to the fa20 now.

Guess what...

[AznKirby]

I don't think cams can be considered "bolt-ons" at stage 2.
Maybe the drop-in ones can, though.

@tahdizzle don't get me wrong the FA20 is great, but the K20 is almost a 15 year old design at the core, 10 years for the K20Z_ models, and it has an amazing specific power. We're talking about Honda stuff here, and you can't deny they make some great engines.

Like you quoted, it's got drawbacks like the cam phaser lag and stuff which I imagine is less of a problem on the FA20 because of ethrottle and phaser+oil system design. But the FA20 has a tiny rod/stroke ratio and fixed cams. Each has its merits.

[swarb]

So what does all this NA KA20 talk have to do with the CTR? other than it's a honda?

NOTHING<-----

Never said that honda didn't make great engines. I'm saying that a k20z3 does NOT make 192 whp stock, and CANNOT make 240whp with bolt ons and a tune.

Well, of course lol. It makes ~200bhp stock and ~250hp with many bolt ons and tune. When your "bolt ons" start involving a really large number of bolts you can up it to like 270.
