Acura 1.8 Ls Non-Vtec
 

--How large can a 1.8l non vtec be bored/stroked to? 2.2 or only 2.0.

I don't know much about bore/stoking an engine.

--Should I bore stroke my engines parts or buy engine parts that are new, higher quality, and then bore them? Or can you buy high quality parts that will fix my engine that are already bored and just swap them in?

Second question is my motor has about 125000 miles on it. I wanted to turbo my Ls motor with a good turbo kit. I was planning on keeping this car for a while and basically doing an engine swap at 250000 miles.

--Is there a turbo kit that will fit my current engine and with minor adjustments also fit an engine that I would be swapping into my LS?

I don't want to spend 4000 on a turbo and have to buy a new turbo when I do an engine swap in 75000 miles.

Also all the turbo kits I can find for my engine are $2000-5000 bucks! Can anyone hook me up with a link for turbos in the 1000-2000 dollar range or is this just not going to happen.

-- Last question what are the internal parts I need to replace if I want over 8 psi of boost? How much will this cost me for the internals.

Re:Acura 1.8 Ls Non-Vtec
 

I heard of a site called homemadeturbo.com thats pretty helpful with building cheap turbo kits ::)

Re:Acura 1.8 Ls Non-Vtec
 

u just asked soooo many questions at once. do a little research.

and by comming to this site.... and asking about where to buy a kit.....isnt smart.

the ls motor can handle a good amount of boost, depending on your fuel management. dont bother boring ---- out, just keep it how it is and boost the fucker. do some searching and check with the faq's and im sure youll have a lot better understanding of how it all works man.

Re:Acura 1.8 Ls Non-Vtec
 

Maybe I don't understand this site. Is it dedicated to building turbos ? Why is asking to buy a turbo not smart?

Even if I build a turbo I still have to BUY the parts. Maybe im missing something. I didnt mean buy a kit I mean buy the parts to build a kit. I am searching posts right now on turbos. And doing research.

Is there a reason that you say "don't bore it out, just leave it stock?" I know this will save me money, besides that any other reason?

When I asked for a link I mean post links or anything on parts. I did not mean Only other web sites.


Lol the thing about homemadeturbo helping with turbos is funny I just mistyped

Re:Acura 1.8 Ls Non-Vtec
 

Why would you bore it out? An LS with a good Home made turbo kit will run 12 second passes at 12 psi or so. Building a turbo? You mean turbo kit? You can get just the turbo, a nice one for under $400. The whole kit if you build it yourself will cost under $1500, and that is what you should do.

Re:Acura 1.8 Ls Non-Vtec
 

the ls motor is stong as it is. when u say building a turbo... u dont actually build a turbo, u build a kit. u get the turbo from another car. look on the main page at all the projects and see what goes into building a kit.

the purpose of this site is to make your car turbo, by using the most cost effective methods possible.

Re:Acura 1.8 Ls Non-Vtec
 

Ok sweet Got it thanks for your quick response and help.

Re:Acura 1.8 Ls Non-Vtec
 

LOL, damn that sounds familiar. Yeah, I mentioned Greddy and Edelbrock just one time, and I got mad ---- talked about me in the forums. I'm still a noob but I learned quick. I didn't get the homemade turbo thing at first. Pssssst... whatever you do, don't say Edelbrock or Greddy. Ummmm.... only say Greddy if you're talking about exhausts. Errrr ummm, maybe they make their own exhausts too????

Re:Acura 1.8 Ls Non-Vtec
 

Hey to answer your question about boring, it will take quite sometime and a lil bit of $. If your not going to resleeve it i wouldnt go past an 84/85 mm bore, anything above is usually for drag purposes and i would definately stay away from it.

Re:Acura 1.8 Ls Non-Vtec
 

Phalse,

Your intentions are good and your grammar/spelling is up to par, but slow down! Hell you nearly got flamed for that craziness. It would have been better to phrase your question in a manor of “what route should I take, this is what I have”. Give us as much detail as possible, tell us all about your car, what it’s done for you, where you’d like to be at the end with it. What kind of experience do you have? Do you at least change your own oil; are you willing to get your hands dirty? What tools do you have, are you willing to invest at least $500 on some equipment (if you don’t have anything)? Some people are better off buying a factory-boosted car (like a dsm), or buying a kit and paying someone to install it. You will be sacrificing reliability once this thing is in full swing, especially if you have no idea what’s going on in the car. Finally, do you have the finances to support this project? A 2nd car is pretty much a must since you can expect your integra to be down for a while (then again that loops back to the finance part).

Take my first segment into high consideration, if you are serious answer all of that and then you can say you’ve taken your first step. If you are going for the bottom end budget build then you’ve come to the right place. The cheapest way to do up a turbo would be to piece together the KIT yourself, checkout the vendors on this site, you can find some high end stuff at great prices (hint-hint Stealthmode, Tuner Toys) . Depending on what turbo you want expect a budget of $100-300 (used), the turbo is a very subjective topic, I will tell you to get a T-25, next person will tell you T3. The rest of the kit is all in what you want.. my hand is still kind of hurting (logging accident) so I can’t really give you the full 2 pages that I would normally write, give me back some input and I can point you someplace.

For the motor, if it’s in good condition, boost what you got already; in worst case just buy a spare one (btw what year/model is your car?). If you want to do a serious setup, look for the keywords “built LS/VTEC” do the research, if something comes up that you can’t answer yourself then comeback for consultation, but we aren’t going to spoon-feed your ass. If you want to run a 2.0 or a 2.2 Honda has many many different motors avail, you can swap anything you need (if your wallet is thick enough).

FYI I’m probably not going to spend over $500 on the turbo/full exhaust setup on my ’90 RS (that is on my to-do list), then again I have the tools and skills (mad skillz) to complete such a flat line project. Check this website found inside the links section on the main page of homemadeturbo.com out for some good reading:

read that 3 times over and come back and ask your questions.

Re:Acura 1.8 Ls Non-Vtec
 

but well put ;)

Re:Acura 1.8 Ls Non-Vtec
 

That was a long post, I will check out those links after I do some more research. Thanks for the information Ryan.

My car has 125000 miles on it.
Its a DOHC ls integra 93'
It has all stock motor except for an cold air intake
It has a 2 inch cat back with exhaust and sounds decent (not too high pitched).
SR preformance cross drilled rotors
new cv joints I just installed,
new struts TOIKO +
lowering springs with a 1 inch drop.
40 series tires with 16 inch white RSL concept rims.

I will post later this weekend after I do some more research. Thanks again for the help, Ryan. Late

Re:Acura 1.8 Ls Non-Vtec
 

Ok, where do we start. I have a '90 RS so I can give you some direction on the car.

You didn't tell me the secifics I needed about your car, you provided me with things that I already know (DOHC) and things I didn't need to know (suspension/brakes), so let us assume your car is a 5 speed LS motor.

What about tools? You willing to make some investments (like $350-500 for a welder setup) in equpiment? Do you have the space to work on the car? Want to get your hands dirty? Do you know how to wield a soldering gun? If you plan on chipping your own ECU then you need to know something about circuit boards and programming. This again goes back to who is installing this thing, if you plan on doing it yourself then you need to supply me with a lot more info about what you can and can't do. Budget Budget Budget, what kinda finances do you have set aside for this project?

If it only has 125k miles on it, inspect the motor, do a compression check and make sure it has all routine maintenance before beginning (timing belt, water pump, belts, hoses). Now would be a good time to consider doing the LS/Vtec swap if that's the route you want to go, while everything is apart. Either way, just ride with that motor, it will last you a good while (with proper maintenance and assuming you haven't beat it to the ground).

Your exhaust is borderline for a turbo setup, is it mandrel bent or crushed bent? If it's crushed bent then expect to replace it all with either a 3" crushed bend or 2.5" mandrel bent one. Flow is everything with a turbo. So if it's a good exhaust that is mandrel bent you can still ride with it, lose the cat. You can always throw it back on for testing but it needs to go with the current setup + boost.


Well since we are keeping your existing motor and possibly existing exhaust (if you follow my advice) then we have these things to pick out. Do you plan on running with or without a/c, this will play a pretty big role in fitment.

Turbo: I wouldn't go with anything crazy, best bet would be a T3 or a T25, this is very negotiable and opinions are all over on this one.

Manifold: The might make your turbo choice real fast for you, do you want to build it yourself? Going for tubular or log style? Think about this one.

Downpipe: Unless you own/plan2buy a welder then this will most likely have to be fabbed up at an exhaust shop to connect to whatever exhaust you go with.

Management: Going for hondata/zdyne or you plan to chip your own? There are other alternatives for rising the fuel but control from the ECU is the best way to go.

Everything else isn't as big of a deal, lines can be made or purchased from stealthmode, charge piping can be made or purchased, but it's not something that is going to be a major decision. Intercooler is another thing that has to be purchased (I doubt you could even think about making your own).

Gather up a list of smaller parts and you should be set, one thing I wouldn't worry about is making fuel adjustments, the stock integra injectors/pump should handle just fine on a non built block that isn't running anything crazy.

Consider some nice toys like MSD spark control, Turbo Timer, Boost Controller, and BOV if you have the budget left over.

Read thru and answer every one of my questions, then you will have a better stance in the planning phase of this project.
