This would be interesting to know, espcially that the Type-S has a high compression ratio...

 

I think the S would last longer but wouldnt make as much power.
But the S is a better platform for future upgrades too.

 

The lower compression the base is a nice start but the head is pretty limiting. I think that is is a toss up if you put dollar to dollar honestly. There are a few base models out there that are putting down close to 400hp. :eek2:

When it comes to FI, is lower compression more important then the cylinder head?

 

The Type R runs the highest compression right? The Top Fuel DC5-R (turbo) gets 493 WHP (it has a bore and stroker kit giving it 2.4L of disp.)....

 

But does that mean it is the safer setup? The debate seems to be which would be better to run for the long term.

If it has that, then it probably is running much lower conpression than stock.

Well.. if it is stroked then they replaced the rods and pistons(especially at 493WHP), so they more than likely are running 9:1 or so.

The base has lower compression, but it is like the tegs, LS are good for pushing more PSI stock than say a GS-R or Type R, but the GS-R And Type R usually pushed more power on stock blocks for two reasons. One being better a better flowing head on both engines, two is somewhat iffy. The higher your compression, the more power you make per pound of boost, but it also runs hotter, and takes less boost to melt the pistons etc.


I think...

All in all it depends on where you are going, if you don't want to touch your head, as far as porting/polishing goes, you are better off starting with a type S. Also with a type S comes a higher revving engine, so you can go with a turbo that might spool a little later, and still have a longer rev range that it will be spooled.

 

hmmm...

any more thoughts on this topic?

 

Well i have a base model and getting the Greddy kit when it comes out, you have to look at it this way. The higher the compression, the more susceptable to detonation you are and let's all face it...detonation is BAD

 

Why GReddy over another company? I am just curious on your thoughts since other kits are already on the base and the GReddy is not out and not tested.

 

Actually, i'm torn between the greddy kit and CN kit...the CN kit is finished but with the greddy kit i can put more parts on as time goes by. It's a hard decision for me...I might just go with the CN kit b/c it has everything that i need...except for the clutch and flywheel which im getting from here. Chris, speaking of trannies, how much power can the organic clutch withstand?

 

I like the CN kit because it is complete. There are still a lot of add-ons that you can do no matter how complete the kit is. I am not pro Cybernation by any means, but I am thinking about selling the kits so I am playing some pros and cons.

 

You should sell the CN kit on here Chris, that'd be a cool thing. Dont worry dude, i know you're not pro (insert turbo company)

 

Still thinking about it. I know it would be cool but their current pricing on it stinks. Since I cannot make any money off the install it is not worth it just yet.

 

that's true, if they were to drop it for you for you to sell it that'd be awesome. You should talk to them and ask...that is, if you do it.

 

If it has that, then it probably is running much lower conpression than stock.

Its actually running 10.4:1.

It was in Super Street. I'll type up in the specs later, I don't have the mag with me. (it was the cover car).

 

I would think that the type s has the best platform to build on overall for being quick and fast at the same time. The money difference between the cars is minimal, and the base is obviously not up to par suspension and package wise. Since all rsx owners like the overall package of their cars, I would think that they would chose the s. It will eventually be quicker for the money, and like I said, would be a better base platform to work from. Cheaper isn't always better. As for the compression being bad for the engine, that is most likely true if it isn't tuned well, but the rsx-s can probably be made pretty reliable with some sufficient tuning. All of it is time and research, but hopefully not at someone's expense. For me I would go with the better engine flow and more power made by compression and take my chances with reliability since I don't think there would be that much of a difference.

 

hondacvcjosh: You have a good point for the S being a good platform and it is a great platform to build engine wise and I'm not doubting that. But there are people out there that want to put their heart and everything they got into their car to make theirs unique. I am one of those people, I chose a base for many reasons, and one of those main reasons was that i could build up that car anyway that i see fit. But you can't deny that the base model isnt a good platform b/c it is.

 

No denying that the base is a good platform, and that it is very refined in relation to most cars. I just said the s was better money and everything else aside. The one thing that would intrigue me about the base that I never quite thought about was the fact that you can be in boost longer for each gear, allowing more spool up time, and possibly giving a little edge to the base in some midrange.

 

assuming all turbo components, install and every other variable being equal, what would a base dyno at compared to a type-s with a stage 1 kit?

 

I believe a stage 1 base model RSX puts about close to 270whp while the S is slightly over 270whp, i think 274...so not a BIG difference but still a difference.

hondacvcjosh: and that's exactly why i chose the base model, think about it everyone, longer gears mean what? more time for boost. just raise the rev limiter on the engine and bam! there ya go...

 

Yesss the base kicks ass....

 

absofreakinglutely...

ummmm...are you sure about that??

as much as i'd like to believe it...i have my doubts about only 4whp less than a type-s.

where does the extra 36whp come from??

 

it's a rough estimate for me, the exact numbers i believe were on the cybernation website...275whp for the type S...i cant find it, but the base model/ep3 puts like 260ish whp i believe, dont quote me on it. You have to remember, lower compression means you can boost more...
