well it seem like this has been the hot topic of late.......the engine swap......it seems to me that everyone who talks about this is talking about putting the 220hp type r motor in their car.......wouldn't it be less of a problem to drop the US spec Type S engine.....i mean obviously the type R is a better NA motor......and you could have the savy of saying..."i dropped the Jspec type R"........but wouldn't it be easier to drop the US spec motor and wouldn't there be more of a choice of parts to choose from the aftermarket. Think about it....there is no bolt on turbo kit for type r integra and very very very few people have turboed them, compression is just too high, there are more parts available for the GSR than the Type R....everyone knows that......they already have a supercharger for the type s (jackson racing, it was at the SEMA show...not sure if its been released yet).......and every major aftermarket company is gonna come out with the bolt on turbo kit for the type s.......right now it just seems to me that everyone is getting the type r motor because it is easier to get.....the us spec motor is tough to get......either find a crashed type s or buy it from the dealer, imagine what they will charge you for the motor...OUCH!

I agree with you, the Type R just doesnt sound that great. Plus, people in cali cant make it legal...and really anywhere where they do SMOG checks, it will not pass. The Type S you can make pass if you goto the DMV and have a ref. look at it and make sure that all the numbers match up, and that everything is legal on the car. I know its lame, and i would never do it, but you could just buy a JDM valve cover and put it on your engine and say that its an R, no one would know. I know i know i know...LAME, im just saying that you could.
Cheers

I think U are right, Now to think of it thats what I would like to do rather than the Type R, but the fact of having a JDM will always be amazing, and u will get more looks and more points in the show!!!

indeed the k20a doesn't sound so appealing to the mass due to the higher compression, but the k20a also comes completely port polished, lsd, lighten fly wheel and other things. some of us are just not looking to tubo charge a car. plus, yes it's cooler to say "a rsx type-r engine" instead of "rsx type-s engine" [IMG]i/expressions/laugh2.gif[/IMG]

Actually the K20A-R engine did not undergo the port and polish method. Honda used something else but I can't describe it. It's supposed to be better than Port and Polishing.

At any rate, it's been covered a lot yet. The Type R isn't here because of emissions, it's not here because of the gasoline it requires - 100 octane.

And it's not worth going forced induction on a K20A2 either. The engine can't handle boost for sheeit. It lives up to Honda's dislike for turbos/superchargers. The K20A3 engine in the Si is the engine worth boosting.

okay so i am going to be falling into some money in about a year and i was thinking of doing a swap and a turbo instead of a new car. but from what i am hearing a type-s engine is not worth throwing a turbo on? so what could engine could i throw in that is worthy of a turbo that will fit in our engine bay? because if i can't get some reasonably gains i was looking towards different cars, but i actually am partial to the civics looks (especially above a wrx, even tho the specs make me think that over so many times). just a few questions... thanks

For all you guys saying the Type S motor is a pain in the neck to turbo and it can't hold boost.....check out this turbo RSX and its video clips.....its in the middle of the page......and they have a $13,000 type s motor that is running 30-40 psi of boost......and pushing upwards of 700hp.......i think it holds boost pretty well........and check out the turbo NSX while your at it!.....HERE!

That car sounded so beautiful!

holy crap 40psi of boost

Of course it'll hold pretty well. Do you think they just slapped on a turbo and called it a day? It takes thousands of dollars to first upgrade the engine internals so that it simply COULD be turboed. No one said it was impossible.

Did you not read ALL of my previous post?

...no duh you should do internals when you turbo a Honda.....but you said that engine can't hold boost for sheeeeit...in your exact words....and i just showed you it could.....30-40 psi...thats holding it.....O and by the way....your 100 octane thing......i believe the octane ratings are different in Japan.....their 100 octane is the same as our 93.......i am pretty sure they use a different octane rating system

Yes this
has been covered before.. the octane rating is different .. there was a link a while bac k with with a chart...[IMG]i/expressions/face-icon-small-disgusted.gif[/IMG]

thanks chenz....you proved my point as well

And I just made myself clear saying it wasn't impossible. If a turbo was just slapped on there, how long do you expect that engine to last? So many people that have turboed the A2 engine end up getting their engines blown in their face. My point is, it would be better and in fact safer to go F/I in the A3.

Octane ratings different? I would like to see that chart. Because I know for a fact if you put 91/92 octane in the K20A engine, you'll get the performance of the A2.
