Hi everyone,

I am thinking about maybe buying a third gen Integra LS and swapping an F20C (the 1st gen honda s2000 engine) into it.

I used to drive a bone stock 1995 Integra GSR in high school. The past few years I drove a 350z and then most recently a maxima (sold the 350z to free up some cash to buy some fancy televisions and cameras and other electronic toys lolz), but I am thinking about switching back to an integra soon, since it was my favorite of all the different types of cars I've driven so far.

This time, though, I want my integra to be at least as fast as my 350z was, if not even a little faster, but, without sacrificing the reliability of a stock honda engine.

So I don't really want to just get an integra and turbocharge it or anything like that, cuz I'm a n00b and wouldn't know how to fix my car when it inevitably had issues from running it on boost, so I wouldn't want to have to pay obscene amounts of money to mechanics constantly to have them maintain my car that always had issues popping up due to being blown or whatever.

So, I think the best would be to just swap in an F20C s2000 engine into it, since that engine makes 240 horsepower stock, so then I'd have myself a nice fast integra with a nice reliable stock s2000 engine which would be a really fun daily driver car I would think with the 240 horsepower and 9000 RPM redline and everything all in just its stock form and then just intake, headers, and exhaust, and that's it, nothing more than that, so would make maybe 250-260 at the crank, that's more than enough for me in a 2,600 lb integra would be at least as fast as my stock 350z was, and yet still super reliable daily driver, so that would be awesome.

I tried to use the search feature to look for answers to the questions I have, but unfortunately the search function on this website seems to be broken right now (it won't return results for any search item of any kind, even the most generic possible search terms like "engine" or "transmission" don't return any results in any forum right now)

So here are my questions:

1. Is this a some what plausible/common engine swap (the honda s2000 F20C engine into a third gen integra)? Like, does it fit easily? Is it a fairly easy swap for most mechanics/tuner shops to reasonably be able to do?

2. What's the best way to acquire a good, stock F20C engine? Roughly, ballpark, around how much money does it cost more or less to buy a good, F20C engine?

3. I live in California. Am I allowed to do this? Like, will having an F20C engine be against the rules? If I get pulled over by a cop, will he write me a fix it ticket for having an F20C engine (even if it's a bone stock F20C engine) and no other mods to my car at all, in my integra? Or when I go to get my smog check, will it be against the rules when I'm there? etc

4. How much horsepower can a stock third generation Integra LS automatic transmission handle? I strongly prefer manual transmission cars (my integra GSR in high school was manual and my 350z was manual) but I have had a severe nerve disorder in my lower spine/pelvis the past few years, and because of this, it has become much more painful for me to drive manual than to drive automatic since it puts more weight on my pelvis/lower back since I can't push on the side footrest with my left leg in manual cars the way I can in automatics to lighten the load on my pelvis/lowerback when I'm sitting. It's hard to explain, but long story short it makes a big difference, and I am in much less physical pain when driving automatics than driving manuals in city driving, and since I intend to use it as my daily driver, this is very important to me, so, my car will have to be automatic.

5. Are there any other automatic transmissions I can/should use instead of the tranny the stock integra ls comes with for when I swap in an F20C engine that would better handle the power or maybe shift faster/better than an LS auto tranny etc? If so, give some examples/advice please.

Thanks!

I would never say anything is impossible, but it looks like to me that your in for more than you can bite off. Just get an S2k. Wont be as beefy and powerful as the 350 but its a start. Oh but you might be out of luck since all Ive ever seen these come in is a 6-speed manual transmission...no autos...and sorry to hear about your condition. Your Integra Chassis was not meant to be a Rear Wheel Drive vehicle and would require much fabrication which would also be more than a few bucks. My suggestion to you is if you want a great, reliable, automatic, yet not too slow, with something to build on would be go for an Acura RSX. Wont be the same as a 350....the Z is incredible and these are 2 way different vehicles.

racebum

the f20 as far as i know has never been done in an integra. i have however seen a chevy 350 in a crx so it's probably possible. what is easy to do in the integra is the k20 swap from the rsx-s or even easier still the jdm itr swap. jdm itr swaps are a direct plug and play. you have 100% honda reliability and a car that does high 14s. that also is where the non hr 350z's run

This is a joke right?

1.You can't put a RWD setup in a teg without some serious mods.
2.3-4k engine/trans, 2k random teg, and probably 10k in fab work.
3.You'll never pass smog and the cops will take you to jail.
4.200whp max or else you'll be rebuilding it soon.
5.no auto will fit to a f20c unless its custom

My suggestion: Buy an older s2k right now for 8-10k and call it day. or buy a gsr again build the engine boost properly and you wont have problems.

Yea, I didn't really take into consideration that the s2000 engine is mounted parallel to the driveshaft since it's rwd instead of parallel to the front axle the way fwd cars like integra engines are, so I can see now why that would make it tricky.

Looks like it would probably be a much better bet to swap in an RSX type-s engine instead, and then after intake/headers/exhaust I guess it would make around 220 crank hp or so, which still wouldn't be quite as awesome as having an f20c engine, but would still make it noticeably faster than my stock integra GSR was back in the day, so it would still be pretty fun.

I'm not sure if it would maybe be tricky to get an rsx type-s engine to mate onto an integra ls automatic transmission though, given that the rsx type-s only came in manual if I remember correctly, so not really sure what that would entail, not to mention how you guys are saying an integra automatic transmission can only handle about 200 whp, and this would be getting pretty close to it after intake/exhaust/headers, so maybe that would be a bad idea.

Is there ANY honda or acura that has an automatic transmission that I could swap into my integra to handle 200+ whp? Like, a prelude tranny or tsx tranny or I dunno, there's gotta be something hopefully.

One thing I am wondering is, I know a lot of the domestic tuners with the muscle cars use automatics even though a lot of them have 500+ whp, but have no problem because there are aftermarket transmissions they can buy, brand new, from aftermarket companies that make strong aftermarket transmissions that can handle big horsepower for a few grand. I was wondering, does this same sort of thing exist for the imports? Like, are there any aftermarket companies that offer transmissions for 3rd gen integras that can handle some horsepower? Cuz if there are, then I could just get one of those and then not have to worry I guess.

there was a f20 dohc vtec that was in the jdm accords. if you go to jdmtigerjapanese.com and check out there motors they have an a large amount to choose from. take a peek and check out your options

TypeRMOBBiN209

these guys did it why can't op? its a civic but its the same ****

sweetdb1

if he is going to do all the fab work to put that motor in he might as well take that money and put a k24 in and spank the hell out of the f20

Billy13

The best swap for an integra imo is the jdm k20a rsx type r motor. my roommate has it done to his 95 integra. all he has are boltons and he makes 220hp to the wheels. with engine, all swap parts and labor it cost him about $15,000. he did buy all the top of the line parts because it is a track car. on a budget swap you could probably get it done for 10k to 12k.

KoreanMoviesFTW

Yea, that sounds like it's probably the most practical way for me to get the type of power I was looking for without turbocharging/nitrousing, Billy, I think I will go with that.

Sweetdb, why would a k24 spank the hell out of a f20c, if both motors were stock or both motors only had intake/headers/exhaust? The f20c has 240 horsepower stock and the k24 has 200 horsepower stock. Wouldn't the f20c spank the k24, not the other way around?

KoreanMoviesFTW

Btw, is the search feature not working for anyone else right now either, or is it on my end? I can't tell if I just have some weird setting or checkbox checked that's messing it up for me or if the search feature is just down for everyone right now.

The ls integra tranny will not mount to a k.I seen that in one of your post.B series and k are know were near alike.I know you have a condtion that does not allow you to drive a stick.If you did slap a RSX-S motor in you would have to mount a none S auto tranny to it.I would think with the none s tranny you wouldnt get all the ponys out of the motor.Making it pointless to do,you can just do a none S k swap cheaper and better for you.Other then that it sounds like you are very new to honda.There is a auto gsr swap you can do a jdm gsr auto motor with tranny cheap and can make some good number's.For a person just getting into the game i would do what is cheap and ez.Going head first into a project that cost so much dam money and not having any know how is bad!This is what i would do Get a auto ls integra swap the auto gsr in add some bolt on's chip the ecu tune it PNp the head and call it a day.

racebum

the k is newer and better due to the larger displacement and slightly better head, but, dollar for dollar, the easy way to hit 200whp all motor is

1. 97 jdm itr swap $3500 from jdm engines corp {this gives you the transmission too, 5spd LSD}
2. s100 ecu $200
3. endyn bumpstix with matching VT $1000
4. might as well change the valve seals when you have the head apart for cams $30
5. tune time $300


with a good exhaust this combo will do 200whp and redline around 9500rpm.

the only downside to this engine is it's life if you drive it hard. 9500rpm is hard on any 4 stroke and the cams have fairly aggressive profiles that put strain on guides and seats, not as bad as skunk pro cams but bad none the less.

Its possible. Some dude on here is building a RWD CRX right now. Check it out in the appearance build thread forums. ITs pretty crazy. Its not about being fast all the time. Its about having something different and making peoples jaw drop when they see it. LOL

racebum

i'm not sure anyones jaw drops over a honda, but, rwd crx has been done. here's a vid

The biggest issue with using an automatic on a type S is getting an ECU to both run the engine and be able to properly control the transmission, nothing stock will work properly.

While it is true there is a JDM automatic GS-R (they're actually called an SiR-G) you can't chip the ECU, even the OBD1 version, they use a square OBD2 style Eprom. As far as swapping hondas goes there aren't really very many options for retaining an automatic.

dudesitsjdm

well i was right about some stuff.I didnt know that about the ecu on the auto sir-g ecu.Thanks for the info!

racebum

long story short if you keep your car automatic you have to run the jdm auto euc for a stock gsr engine. this can be an issue in some states getting it to pass since a US scan tool can not access it

KoreanMoviesFTW

Well ty for all the advice guys, I appreciate it very much. I think I have a better understanding now of more or less what my options are. I think I'm gonna just wait and see if my condition improves, and if it doesn't, then I will probably just hold on to the maxima as my daily driver and build an integra as just a racing/fun car to have on the side to use on the rare times I'm having a good day etc, or if it does improve then at that point I'll make a K-engine daily driver teggy.

can be done, this hatch has a corvette ls1 rwd of course
