I was reading through Hondas website, and they had an Accord with a TSX engine and tranny bolted up to a GReddy turbo. I can't find pics, but here is the info listed about the car. I know some of you are more knowledgeable about this type of info, but is it just a prototype like the Dazz/HKS TSX?
If a turbo kit/ supercharger kit was available for the Accord 2.4l, would it be a direct bolt on? I don't know any differences of the Accord 4 cyl vs the TSX 4 cyl.
Anyways, here's what was listed on Hondas site-->



Honda Factory Performance (HFP)/Ro_Ja Honda Accord Concept

The Honda Factory Performance (HFP)/Ro_Ja Honda Accord Concept makes its debut in the Honda display at SEMA. It was developed as a collaboration between industry icon RJ deVera and Honda Factory Performance. The goal was to combine aftermarket products, Honda factory components and HFP accessories to create a car that meets the demands of today's enthusiast buyers. To do it, the Accord Coupe received a 2.4-liter i-VTEC TSX engine and a TSX close-ratio 6-speed manual transmission, a Pure Styling Ro_Ja Ground Effects Kit, Sparco racing seats, 19-inch Ro_Ja Forged wheels and BF Goodrich tires. Leading aftermarket companies GReddy Performance Products USA, Circuit Worx, and Street Concepts pitched in to help make the concept a wildly creative, yet purely Honda vision of the Accord Coupe.

hmmm that's interesting. Then again, if you're honda, you can just ask the boys in the ECU department to whip up something interesting for your turbo project.

WTF?! Does this mean they could come out with a production model w/ aftermarket products like a GReddy turbo? If this happened, Honda would dominate all.....Keep us posted, and thanks for the info.

 

Here is a link for pics of the bad machine:

Oh that car. I saw that a year or so ago. I guess not much has happend since...

 

The interesting thing is, it's being done on a stock TSX engine.

 

I wonder why they didn't use the stock K24 the accord has that makes 160HP. I imagine the compression ratio and piston speeds are much lower.

 

Why make just 160 when you can make 200? Plus you know they knew the engine can take it. I would like to see the some times and dynos on that car! And GReddy, where's my turbo?

 

I went the NY auto show last year and saw that exact same car. There was a tent outside of the Javit's Center with about 10 modded cars is it. I have picture of the accord at home. I'll try to post some pictures of it when I get home after the weekend.

It has a the same modds as the one you saw except the CF hood...but my pictures are almost a year old.

 

You could simply increase the boost and there would be no difference between 160 and 200. Theoretically you could boost the 160hp k24 more, but for Honda OEM HFP I can understand their need for reliability, so they probably didn't want to turn up the boost too much.

 

Could you elaborate on that? Are you talking about the compression ratio difference? You may boost the 160 hp motor more but have the same results or still be behind the TSX 200 hp motor. Nothing like a 40 hp head start.

 

you should definately read up about forced induction. i'll give an example, 160HP K24 lets assume has a 8.5:1 compression ratio. Our 200HP K24A2 has a 10.5:1 An engine with a high compression ratio will not be able to take as much boost as a lesser CR as the air in the cyclinder is already highly pressurized. So a 160HP engine w/ low compression ratio might be able to take 16psi of boost and produce 350HP, while a 200HP engine w/ high CR might only take 6psi of boost and produce 280HP. There is a tradeoff w/ high CR and reliability of boost, in general an engine w/ low CR has better turboing potential for very high HP.

This is the reason a lot of turbo'd RSXs with the highest HP #'s are bases, because they have the 160HP K20 engine rather than the high CR RSX-S 200HP engine.

 

Just to elaborate further on xizor's info, a stock engine will not be able to accept large amounts of boost. What many truly high performance engines need to do in order to run both high compression and high boost is reinforce the block, cylinder heads, head bolts, gaskets, and a variety of other parts.

Proper forced induction can provide serious power. Inproper forced induction can result in a huge drain on your wallet.

 

Honda makes reliable cars. Production model or concept car, they would not put so much boost as to make the car unreliable. If they swapped the engine, it was for a reason. With a MODEST amount of boost, the results would be similiar or the K24A2 would be slightly ahead. You will maintain a higher degree of reliability with more modest boost and starting with more HP. Maybe you should think before you accuse someone of being ignorant.

 

 

I'm with ya Xizor.

 

I'll reserve my opinion until more data is available. It's still a little early to tell what our stock engine is really capable of but I'm planning to find out. I'd rather work with real numbers and results than speculations. Keep in mind it's the tuning that makes the difference in the end.

 

Turbo would be nice...but where the fuck is Hondata someone needs to light a fire under their asses

 

This is late, but the piston speeds are the same (since the stroke is the same).

 

Where are you hondata!

 

Adding to this statement, since you are so up on turbocharging, I am certain you read about the HKS turbo'ed TSX putting 370 HP to the wheels. That was using the TSX's compression ratio with 15psi of boost. I think that is more than a modest amount of boost, and the car obviously puts down plenty of power. Honda wanted to show us what the high-performance TSX engine could do; that is why they swapped it into the car in the first place.

 

That car is no where close to a daily driver. I think that makes a difference.

 

i didn't read the detailed article in honda tuning so I don't know if they built up the engine, but there's no way in hell I'd put 15psi into a k24A2 without building up the internals.

 

Here is more info. So make an opiniom Jtso lol. I called Greddy about this a while back. I swear I posted about it somewhere, oh well. The turbo kit is not functional. It was a one off kit that Greddy had no plans on producing. It was made only for that one show car. Call them if you don't believe me. Hope that answers some questions. And yes I too wish they would make it but they aren't.

 

The engine was stock. The turbo was just bolted on. The compression ratio of the K24A2 is not as high as the the RSX-S, but it is a bit higher than the Accord K24. According to the article, the engine can "hold up to quite a bit pretty reliably". That's not to say the lower compression K24 can't hold up the same, but how much more boost than 15 do you really want running on any stock engine, Honda or otherwise?

 

Evo's run 20+, not that anyone needs that. But like it was said before, the Dazz turbo was a onetime thing and has no long term reliability stats. If the block can hold up that's great, but I base my opinion on the fact that base RSX engines can boost a ton more than RSX-S ones.
