What can i do to increase my HP??

Question

I have a 1996 acura integra, i have headers, exhaust cold air intake, but i want more power whats next besides turbo, or supercharge?????

Answer 1

Although what the previous person listed is very advantageous to what you would like to do, on a naturally asperated engine, you will under no circumstances get 3 to 400 HP out of your integ unless you already are looking down the barrel of 200 hp off your engine to begin with... flywheel hp and the hp that is transfered to the wheels are 2 diff numbers, of which niether will be at 300 with the list of modifications given by the gentleman above... with naturally asperated engines, the idea is to bring the compression of the engine as high as possible while still staying in a range of no excessive overheating... you first need to examine the life of your car, without good life youre throwing your money away... if you find worn out parts on the bottom or top part of your engine REPLACE! which is common knowledge... but if you are trying to get 300 hp out of a sohc 1.6 liter then i hate to bust your bubble but youre going to HAVE to have turbo or super setup... yes tuning is the best thing when you modify your car, but here is what I have learned in doing this for myself on many cars....

1) the hp incease you will get will NEVER be that of the advertisements you see on the listings of modifications unless you have a full racing setup already... example= 10-15 hp on a performance muffler exhaust manifold (header).... dyno tests have proven this isnt the case unless you have a fully ported system running straight cat and pretty much no muffler on a larger diameter pipe than stock...

2) intake/header/exhaust combo is great! BUT you must learn what the above person stated about basically what i call your weakest link... if you have a 4 inch diameter pipe on your intake flowing into a 2 inch diameter throttle body... HMMMM does that help? thats why increaseing diameters with custom or aftermarket manifolds are great...

3) and lastly YOU GET WHAT YOU PAY FOR! brand names with seemingly high prices have been tested time and time again for durablitiy, longevity, and effectiveness...

the best way to bump compression is boring your motor out, higher compression pistons (in turn more durable rods), thinner head gaskets... among others...

sorry if my spelling is bad, im not going back to read what I have already wrote.... if you drop 2 thousand in your car basically building your car from the ground up then yes, you could possibly be reaching close to 300 hp with a good tune and at least a DOHC engine with vtec... but its hard to go natually asperated on smaller engines without some major cash....

I on the other hand have a 1993 honda dx with a built motor and forced induction... i range anywhere from 275 to 350 hp in accordance to my turbo... on a 1.6 Liter sohc.... just do research man, thats what i did... just have fun in whatever you do avove all else....

Answer 2

Superchargers are junk for engines that small. You need a turbo.

While a supercharger makes a more consistent intake charge because it doesn't have to spool up, it is driven by a belt that attatches to the crank pulley. As it is giving you power from the charged intake air, it takes it away by adding resistance at the crankshaft.

A turbo is free horsepower - since it works off of exhaust flow it takes away no power and can be set up to give much more of a gain than a supercharger can.

But you said you didn't want to force feed the engine, so here are some tips to making more power with a naturally aspirated engine. You have more airflow with the CAI and exhaust, but that airflow is almost useless to you, and I'm going to tell you why.

The heads on your car were designed to flow as much air in and out as the stock intake and exhaust could allow. All of the extra air your providing basically comes to a bottleneck at the heads. However, a little of the extra will get in, but it will also have trouble getting out through the exhaust.

What you need to do is remove the heads and take them to a shop that does machine work. Get them ported and polished. While you have the heads off you'll want to change the cam(s) to longer duration ones, because you'll run into the same problem as before if your valves only open up long enough to let the stock amount of intake in. For more accurate timing you may want to ditch the timing chain in exchange for a set of timing gears.

After that you'll want to upgrade your fuel and ignition systems. Get a better throttle body, fuel pump, fuel rails and better injectors. For the ignition you'll need a better coil, better wires and you'll want to change the plugs.

Now's the time to tune your computer (if you have the cash, upgrade to the new AEM ECU first). If you don't do all of this at once, you'll want to take the car to a dyno shop for a tune each time you add a few mods. If you do all of this stuff at once then just have it tuned when you're done.

You're looking at 3-400bhp right there, with no boost lag and no power robbing supercharger.

Oh yeah, someone above mentioned nitrous. If you decide to put the car on a bottle then you'll probably want to replace the pistons and rods with forged units. That's really a good idea even if you don't do the nitrous, it will make the engine last much longer. 400 ponies put a lot of stress on the insides, especially at high RPMs.

If you can't afford all of this stuff, which is probably the case, I recommend the AEM ECU. It would be the single most advantageous modification I've listed. If you can afford it, the port job would do wonders when coupled with the new ECU.

Force induction will result in complicated modification works such as the fuel system & the air intake system. Acura engines are designed for NA performance.My opinion is that you may wish to bore your throttle body. There are ready bored throttle bodies in the market such as Toda bored venturi throttle body. I also recommend that you get a performance cat back full exhaust system such as Fujitsubo.

2ndly comes the engine internal works. You may wish to send your cylinder head to King Motorsports for a 3 angle valve job. At the same time, it is highly recommended to change your camshaft to those high profile camshaft kits (comes with performance valve spring) such as Toda or Spoon.You can also send your cylinder block for honing & you replace your B16 with a Toda 1800cc stroker kit. The whole engine assembly will be complete with a Toda cylinder head gasket & a Hondata ECU.

You will also need to upgrade your transmission system to complement with the high power output. I recommend chaging your clutch assembly to either the Toda chroly moly flywheel/high power output clutch kit or ATS Pro Spec Magnum clutch/carbon steel flywheel kit. Next comes the Limited Slip Differential. ATS/Carbonetics carbon LSD is highly recommended. Alternative choice is Quaife Active Torque Biased (ATB)Differential. Lastly what your need is a Spoon or ATS final drive gear to complete the whole transmission assembly.

Answer 4

Get yourself an Engine managment system, there is many gains by having one. The downside is you need it to be tuned by a pro. If it's done wrong then your motor could have problems and get destroyed.

Answer 5

don't go with a turbo,if anything go with a super charger,,there better for producing more power and easier on he engine also,you can also order a high performance computer for it,,that will help it a whole lot,,good luck have a good x-mas.

Answer 6

for $ 400. if you have the DOHC V-TEC GSR motor. change the

pistons to the Type-R pistons, it adds at least 20 - 40 HP maybe

even more. Its more compression

Answer 7

the cheapest way is for you to take it to a shop and have them dyno-tune it!$200-600

Answer 8

Get the ECU reprogrammed.

Answer 9

buy a fast car

Answer 10

new chip maybe, you did all the cheap stuff.
