Hello.
How reliable is K20/K24 setup? It has oil pump cavitation problems, very narrow rod bearing (only 15mm), pistons speed at high rpm is extremely high and this leads to detonation problems. What do you think about this combo for a turbo setup? Is it reliable?
Thank you in advance.

 

Motor won't have too many issues when you start boosting but gears will need to be looked into.

 

If built properly, the combo should be very reliable. Of coarse, the best option would be to just go with a tsx K24a2, right from factory if you are worried about it.

Boosting a Honda engine will affect the life span of the engine, but many variables are involved

 

Is it better to get a K24a2 into a stock rsx then eventually get a k20 head. Or is a k20A better to start off with. Is the K24 significantly heavier and would it do anything to the handling of the and rsx?

 

I think it's time you start reading up on the many threads about K series.

The K24A2 has basically the "same" head as the K20A2 head, pointless to change, of coarse if you read up on the engines, you'd know this.

Weight difference between the 2 and 2.4L, next to nothing, 20-30 lbs maybe......trust me, that is NOT an issue

 

 

If I'm not mistaken,the k20a2 head has bigger ports than the k24a2 head..but,overall the k24a2 longblock is a great starting point..
-has real i-vtec
-higher compression pistons
-better cams
Than other k24 blocks

if you are gonna build the bottom end it doesnt matter what one and the k20 head flows a little better than a tsx.

 

transmission worries me the most.

 

if it bothers you so much, buy a 5 speed, they have zero issues

 

I've always heard they are the weakest one..

 

You are greatly mistakin. I have worked for Acura for years, and been around hundreds of rsx models, this is simply NOT true.....don't give in to hearsay bro

 

Idk what working for Acura would tell you. You can't compare cars when one has 130whp and a 6800rpm rev limit to a type s that is driven by lots Ricers. I've been around k series for a while and always thought the 2nd-3rd gear was notoriously weak. I had an ep3 and tons of people on the forums were always battling dealerships bc their trannies would grind. And that's with weak *** motors and no revs not like all motor k24 with 230-250whp.

And not to mention the ratios in the base Rsx are garbage.

 

LOL, 1st off, there is no such thing as a 130hp rsx!!

What does Acura have to do with anything? Well, lets see, i would be the one ordering parts for both cars that were and were not on warranty, including transmission parts. We did replace parts to fix 2nd and 3rd gear grind issues on some type S models. We never had and issues with base transmissions.

We also had an rsx club with 140 members, funny, not a single not of the base owners had any issues with theirs either, even over the eight years the club existed. If you had issues with his EP3, you probably have poor driving skills and wrecked the gears yourself

As far as having 200+ hp, one gear in a type S tranny, is no stronger that that of the base

 

where does it say my gears grinded? your post is hilarious and just proves you dont know what you are talking about..


a base rsx makes ~130whp.. do you know what whp stands for?


how do you not understand what i said when i explained why it isnt fair to compare a 130whp cars transmission failures when talking about the integrity of the tranny? people who buy the type s are going to drive it harder or they wouldnt have spent the cash. like i said the 6800 rev limit compared to 8000 will also protect the tranny. do you know how rpm's effect a trannies life and integrity? probably not but humor me. and then there is the more hp thing the type s has.


what im saying is from people with built engines, NA or turbo ive been told the 5 speeds arent all that. and like i said even if they were the ratios are dog ****. especially the base rsx. the ep3 has better ratios and final drive so its not as terrible but still crazy.


but tell me again why being a parts guy at an acura dealership makes you qualified to talk about boosted "race cars"? last time i was at the dealership getting a few things the guy was trying to tell me how k series was junk and b series was still the best. after i told him i was all motor especially lol.

and the 2nd gear grind was a known problem at the dealers with the ep3 tranny just like it was with the 3rd gear in the 06 si's. not from a few bone heads that couldnt drive. if you want to see my driving skills ill gladly let you put your foot in your mouth.

 

what ever dood, i could argue half of what you just said, not worth my time....and i never once talked about gear ratio's or eps tranny's prolems....do/say what ever the hell floats your boat. btw, the last stock base rsx i dyno'd made 142whp, not 130

 

you must be trolling

 

k transmissions are crap. you are both arguing about the same point. no matter 5 or 6 speed they both suck.

 

but but but he said the 5's have zero issues brah

 

ill agree to an extent
2nd or 3rd gear will pretty much always be the first gears to mess up on any tranny
2nd gear went bad on my boys 06 si but he drives the **** out of hit


but the 06 si is better overall that the rsx or rsx type-s or the ep3 si
the ep3, and rsx's clearly fall behind in overall performance to the 06
so why more people run rsx k20's confuses me , maybe cause they think there good and have the letter K in it and they cost less


but like deetz said people can argue all day ups and downs and all that and we dont want to do all that, just stating some stuff is all

 

but to answer the original question

its all about what u want to do
if you want to keep it all motor and rev to red line youll b fine
if u want to run a turbo on stock internals and run 35lbs you probably wont be fine lol

 

none of that makes ANY sense.

 

Lol this. People are clueless.

 

Let me dumb this down. Saying a type s trans is weaker bc they break more is like Ferrari saying their cars are more reliable because they serviced fewer cars last year than honda. Not taking into the fact they Honda sells more cars in a few hours nation wide than they do in a whole year.

Everyone has type s trannies in their built cars. Very very few peoe have 5 speeds. Same with z3 trannies they aren't as easy to swap. Just because base Rsx trannies dont break at 130whp with old people driving them doesn't mean they are stronger. There's Probably more type s tranny kswapped hatches in 1 major city than there is swapped cars using a 5 speed in the nation. So of course they break more.


If I owned a fast food restaurant this would be my claim. "my place is cleaner than McDonald's bc we had less cases of food poisoning last year". When I'm 1 place and there are how many McDonald's.


Btw I made 30+ passes last year with 02-04 type s gears, 300+ whp and full throttle shifts every time. In a heavy car at that. Never a lockout or grind. doing a stroker now so I'm sure it's gonna break but any k tranny would. Except an Rsx 5 speed would probably make my car a second slower lol.
