Hello
I was recently looking at one of my Honda tuning magazines and i came across a turbo kit for a 1992 Honda Civic SI. Now, if i put that onto a 92 SI would i need, stronger pistons and connecting rods. I asked my father about it and he was saying, those engines are not designed to have 9psi going into a stock motor. So would i need to upgrade the engine internally, or could i just bold it right on. And how reliable would it be, he was also saying that with 9psi going into the engine it would probably blow the motor.
Thanks

Here you will find what everyone is doing to their D16.
And I have heard of dseries engines holding up to 15 psi YES THATS RIGHT, on stock rods. BUT! this is able to be done with the absolute best tuning possible. Without tuning, it WILL be blown because of detonation. Even if you do a bolt on, and run it like it sits w/o any other work being done, you MUST take it to a dyno and have it tuned. There is NO cheap way so add a turbo. Remember this! Not to mention allll the additions needed for a turbo. (ignition, injectors, fuel pump) plus recommended things like (LSD, axles) oh, and according to what kind of turbo you get, say bye bye to the power steering and the A/C, because it just wont fit.
Dont get me wrong, I love turbo’s and I love Civics. But most people just dont understand the DEPTH one has to do in order to get one. Its never just, hey Im gonna spend 1500 on a turbo, slap it on, and ride. no no no….
If I were you, I would go and basically get another block. Go find a cheap D16Z6 block (the one out of your 92 SI) and take this block and make sure the crank is good on it and still balanced. Take the pistons and rods out, buy Eagle Rods ($300) and mount them to Suzuki Vitara Pistons for D-series motors ($130) these are soooo cheap, but literally hundreds if not thousands have been using these on their relatively low power levels of under 350hp. Then, after you do this, you will have a car that you will NEVER have to worry about detonation giving a stock rod a vacation through the block. Then, take your motor out, mount everything back together, and slap on the other block, and BAM, you have a bad little single cam when you get that turbo on and tuned.

yes and no a stock motor will hold 5 psi now you want to run a bigger boost you have to get lower compression pistons and a stronger crank .
If the waste gate is working, so it won’t over boost,you may stand a chance.As soon as it malfunctions, over boost,or your compression rings are a little tired, by-by engine.Ask GM when they built the buick Grand Sport, boom!!, Because they tried to take short cuts.
this remind me of an old beavis and butthead episode. Were one says if you polish a turd its still a turd.
Just leave the little Si alone and drive it.
Put a turbo on a old civic and asks”And how reliable would it be, ”
LOL think what you are saying. duh
when you start thinking of forced induction, there needs to be a few clarifications.
You can absolutely stick a turbo on a completely stock civic, but youre not going to be getting the most potential out of it. for half the price of a turbo you could pretty much get the same amount of power by upgrading the internals. Theres no point on spending $2000 to get you 15-20 hp because the engine is bone stock. build up the engine first, then you will be able to use much higher boost and get alot more horsepower.
“And how reliable would it be”
exactly. youd have forced induction on stock parts… this is a blown motor waiting to happen.
> would i need, stronger pistons
That all depends on what PSI you dial in
> or could i just bold it right on.
You’ll have to dial the PSI down and learn a lot about ignition timing or ECU programming. Or spend $$ by the bucket full for every visit to the speed shop. BUT…
Turbos’ are kind of like jumping into the deep end the very first time. Maybe you should start little slowly. I’ve had 94 Civic EX (for the past 1 year). Recently I found out that the timing was advance too far. It had 16 degree (factory setting) plus extra 15 degree of timing (total of 31 degree). When I took out some timing (to 16 degree & 8 degree extra = total of 24 degree), I noticed tremendous mid range power. Then when I set it to factory 16 degree (total), I noticed wheel spinning, off the line torque. With 31 degrees of timing I could not even get the wheels to churp. Now I get the wheels to spin even just by mistake. I also have short air intake and exhaust headers.
I think these are the kind of “first timer” mods you should try. I learned a lot about engines while researching why my engine knocks (ECU, sensors – MAP, WT, AT, etc). These are the basics. My next stop would be a chip upgrade get some extra timing in the mid range without affecting the off the line torque. All these knowledge would be very useful if I ever get to forced induction.
First off yes you can put it on your motor with no mods, as long as you do not boost over 6-7 PSI. All motors from the factory do not perform at their max potential anyway. Another thing to consider is how good of shape is the engine in? If it has over 150,000 then I would suggest either an engine swap, or a complete build. Also if you swaped in a B16 or B18, you will get the same HP as the turbo kit, plus you would have a much better platform to build on. and if money allowed in the future you could always boost the swaped motor and have more than double of what the boosted stock motor is. heres some food for thought, SOHC stock motor 113 hp to the front wheels, boosted around 160 to the wheels, stock B16 145 hp to the wheels, boosted 250 hp to the wheels, B18 152 hp to the wheels, boosted 270 hp to the wheels. these are numbers from a stock motor internally. Right now I have a 99 civic EX with a B16 swap that is built from the crank up and sleeved that holds 35 PSI of boost and puts down 497 HP, this is what I race on. And every day driving at 15 PSI it puts down 337 Hp these are numbers to the wheels.
yes you would. the engine would need to have stronger interior parts to it can handle the extra boost that you’re giving to the engine. unless you like a lot of power /turbo lag.
