    Turboing an 89 Accord LX-i

    Ok, I just got an 89 Accord LX-i Sedan to use as a project car. I was wanting to turbo it but don't really know much about them and was wondering is it even possible to get 250+ HP out of the A20A3 that is in it? The car right now has an auto trans and i was planning on having the motor rebuilt (and probably strengthened so I don't blow it). If it can be done what all would i need in order to make it work? Thanks for the help!

    Re: Turboing an 89 Accord LX-i

    First off, Welcome

    2nd, search will become your friend.

    however. personally I haven't heard of anyone with that kind of power.

    >.> I know one look got like 170 with N/A *and alot of work*

    several have done boost but with obd conversions.

    and the fact that its a auto will probably limit you from reaching that power *or wanting to* because I don't think there are ways to get it to handle that right.

    but hey I may be wrong, and give it 20 or so minutes and someone with WAYYY more knowledge then me will post. ;D got it.


    again welcome.

    yes it can be done, but be willing to spend at least 5grand on your parts, not including install and a final tune.

    Re: Turboing an 89 Accord LX-i

    I figured that it wouldnt be cheap to do but what all would I need? Also would the auto trans hold up to it or would I need to get a different one?

    Re: Turboing an 89 Accord LX-i

    Even if you rebuild the trans i dont see it holding very long. you will need a 5-speed swap and good clutch kit. You can do the motor rebuild, trans swap and turbo it for around 3k but you wont be at 250hp. for those numbers your looking 4-5k+. other then the motor and trans work its all custom work from turbo manifold, downpipe and exhaust to wiring and tuning. I had everything to do my turbo setup a few years ago and i was just over 2k, but everything was done by me and my buddy and i got parts at a very good price, got rid of the car before i had the chance to put it all in though and probably would have cost a little more to tweak some things. 2500 is a fair estimate for a mild turbo setup with staying obd0 and keeping custom work to a minimum as long as you do all the work involved, but you wont be close to 250hp probably 175-200.

    Thanks for the info. And I was talking about trans, sorry. But knowing what turbo would work would help too.

    Re: Turboing an 89 Accord LX-i

    yea, if i ever get all my parts lined up right ill see about turning the boost up on my set up and making 250 on the stock bottom end ahaha. that would be sweet.

    ohh and ud need a stage3 or higher clutch if u want 250 so add that into the 5speed swap. my stage 3 was 280shipped.

    the only trans that works with the a20 is the a20"s manual 5-speed.
    there is almost no after market support with these motors

    Re: Turboing an 89 Accord LX-i

    yea, the early integra gears swap out with the accord ones, but you would only want to do that if your staying NA cuz they are super fucking short.

    but there is support, its just harder to find, do alot of research on the forums and all ur questions will be answered before you can ask.

    Re: Turboing an 89 Accord LX-i

    turbo is about the only way to go fast with an a20. The big thing is the tune and managemant are very important. If you have a quality tune, it might be doable in a stock shortblock but youll be better off longevity wise with a slightly modified shortblock... the weak link is def the pistons. Thats about it, but if your gonna change the pistons, get forged pistons and get forged rods too, cheap insurance. Thats about all you really need to do with the shortblock, and the supporting machine work. The head doesnt flow that well but if your only looking for 250hp you should be fine with that and maybe a cheap used B16 intake manifold and throttle body portmatched to the stock head and youll pick up some power. But remember, even if the engine is built, it wont last if its untuned, esp on pump gas. And please, swap to 5 speed. The auto wont hold up long... In my LXI i went from running 17.3 1/4 mile times to 13s on the SAME STOCK ENGINE just running a hacked up turbo setup (my first setup, SAFC, 450cc injectors and a BTM!!!) on STREET TIRES with 2.4 60FTS! Anyway, my friend was running mid 12s and he still couldnt beat my trap speeds (105-106mph). And that was on about 13psi boost, UNTUNED, Stock EVERYTHING. So def wayy more left in the car, even at that point... I have a new race setup that I have of yet to dyno, getting divorced

    Re: Turboing an 89 Accord LX-i

    O boi. WHere even to start. I would research research and research and research. PLENTY of info on here

    I asked the same question you did. TOOK me 4 yrs. to collect and even get the point sense i had no one to teach me. First setup i had was a very solid setup. Setup i have now is race setup. BUT i need to obd1 which already i have well over 900. Wiring,dizzy,ecu chipped,tuning,wideband,

    Turbo and manifold alone is 1000. IM not trying to scare you away. BUT you have to be willing to throw that type of cash to get these old girls to move. ITS not a CIVIC. Like the saying goes. IF you want a fast car Then a 3g is NOT for YOU.

    SO my suggestion is Take in the info that the guys told ya and go Read some more. THere is a Forced induction faq. It well tell you everything you need. GO see other people setups and go off that. I learned alot from HMT.com BTW WELCOME and hope you get er done. I would like to see another boosted accord. there is only a few of us left in this world with a 3g that is boosted. LOL

    BTW everything is custom. NO one makes manifolds unless you have one made from one of the members here. Pretty much build what you want. DOnt have to be fancy. SHIT mine wasnt NEAR as fancy LOL. it was True HMT.

    True but he also blew a good bit of parts getting there. Not to mention it sat for awhile because of that. I remember the videos up on youtube.

    I plan to get there myself, but I want to get a good N/A build first.

    Re: Turboing an 89 Accord LX-i

    Ok,kewl and thanks a lot. I'm still pretty much in the researching stage now trying to learn what can and cannot be done. I just got the car a few days ago and don't really plan on getting much for it right off the bat except fixing the driver door. It's all research for the time being until I start to get a list together of what ill need and actually start buying parts.
