From what i know the LS motor is perfect for turbocharging. Out of the three 1.8's Acura offers the LS has the torque especially for a fraction of the price of the oh so hyped up VTEC motors. So what is it that makes the LS motor unfavorable and this is my question. The only thing that the VTEC motors have are stronger internals like the crank, better rods and a higher revving head(which is questionably a necessity for turbocharging)? Please someone just talk to me.

 

A turbocharged GSR will still out run a turbocharged LS, to me the "hype" is worth it.
but if you have an LS, go turbo you wont regret it.

They both can be damn fast... Go with what your budget allows basically. You can't go wrong either way. I'm turboing my B18B and in the end it will be plenty fast for my needs. You can build a B18B for the same price of a B18C1 PnP the head and you'll be able to put out sick numbers

 

i dont know about you guys... but im starting to see alot of these "LS turbo" threads. ARGGHH!

 

Pros: 9.2:1 compression
price/availability
rod/stroke ratio(good for midrange torque and extra displacement)
MORE BOOST!

Cons: rod/stroke ratio(bad for high revs)
head does not flow as well


to me, the pros out wiegh the cons if all u want is a fast street car.

i think the reason we see so many turbo LS threads is cause us LS guys are always pumping up the turbo LS. its hard to find unhappy turbo LS owners.

damn straight

 

A turbo vtec will be faster than a LS, given stock components. Not only from having more hp from the start but the fact that with a higher redline, the engine will flow more air and support a bigger turbo. And bigger turbo means more power.

Higher revs aren't a necessity, but how much air your engine can flow is. How much your engine flows relates to it's displacement and revs among other things, and given the small size of Honda engines, the way to increase flow is to increase the redline. And don't make it sound like stronger internals aren't a big deal (unless you plan to replace them) because it is.

Ultimately if you want the most power, LS isn't the way to do it for the reasons above. But if you want a fast street car for not much cash then it's a great choice.

 

there are no cons to putting a turbo on your car. Just work with what you have and have some fun with it. Throw the turbo on there and you wont regret it.

 

TurboInteg95, well said.

 

actually the turbo ls i believe responds better then the B18c1 turbo. stright from the get go and less tunning. jeffs hosted my pictures for me. thats what my setup used too look like until some one stole my ****. lhttps://honda-tech.com/zerothread?id=184027

 

Turbo VTEC motors suck because the vtec is disengaged when the turbo is put on

 

id prefer a turbo vtec motor becuase of the increased rod bolt / rod strength.

 

shutup, you have no clue what you are talking about

 

supercharger OWNZ!!!!!!!!!!!!!!!!!!!!!!!!

 

calm down man, that was a fine note of sarcasm you ran into

Rob

 

Take and Keep your LS block, buy a b16 head....THEN turbo....good qualities of LS, with much better head air flow.

 

If you turbo either one of these motors you will be happy. I have a turbocharged LS in a 91 Integra and @ 10psi I have beaten many C5 Vettes from 2nd gear onwards. For a daily driver that weighs 3000 pounds with me in it, thats not bad. The motor is built to handle 20psi but I am so tickled with 10psi that I have not cranked the boost up yet. I don't know what she will run et-wise because I will never through a slick under it, but I know she will mph well. LS or Vtec it doesn't matter (its a personal perference), the turbo will make anything fly if you got the right parts and good tuning skills. (I am just speaking for myself and my setup, this is not a general statement) I am very content with my LS and don't dispute vtec is also another killer when turbocharged.

 

F.I. generally amplifies what a motor already does to a higher level. All things equal, a turbo B18B will be a mid range torque monster, and a turbo B18C1 will pull harder on the top end... no mystery there.

 

OK potato boy. I have no clue whatsoever......

 

Take the Ls and do a deck plate motor with GE. Give it time but mark my works the LS short blocks are going to be the ones to get in a short while. Dont get me wrong the vtec head flows better but the LS block is the hot ticket not cause of the low compression but the displacement.

 

I'm sorry, but the ~30 cc in displacement isn't going to make very much of a difference. The LS get's it's characteristics from it's r/s ratio.

 

Yeah, what do you think the step deck does?? Actually i dont think that it increases displacement in any way whatsoever----correct me if im wrong Josh.

 

I've seen some good LS turbo times, but I dont think I ever seen a boosted GSR.

What do people with turboed GSR's usually hit?

 

I'm referring to how he compares the LS block to the GSR block, since so many people talk about how the LS is so much more torquey because of it's greater displacement.

The step deck plate increases the displacement way more than 30cc, it increases it by about ~200cc. This is the golden eagle one you are talking about correct?

 

PRO: everything

CON: nothing
