Dyno/tuned today at 19 psi and pump 92, at Torque Freaks. 261.75 hp and 272.43 torque. Mods in profile, what would I need to reach the 300hp goal without nos, race gas or going into the internals of the engine or head. I would like to keep the turbo I have but might consider going a bit bigger, possibly evo 3.
 
I noticed you don't have CAMS. Put some HKS 272's or FP2's and you should close that gap even further. The EVOIII 16G will give you that extra flow at 19 psi which will yield maybe another 15-20WHP extra plus the cams can give you about the same 15-20WHP.
 
You seems to have a good setup alrdy but the 300HP is gonna have to come with some cams if you plan on keeping your Small 16G. Cams and a ported 2G manifold should do the trick.

Yes go with the 272's, it will give you alot of power up top which is what you need on your FWD. Im sure your puttin on a smoke show right now with that much power. If you want extra HP with 0 dollars spent, go to the muffler shop and cut your exhaust off right BEFORE the gas tank and dump it on the ground. You will gain HP that way but lose a little torque. You wont loose much torque tho, i drop it to 2nd at 35 and break the wheels loose until i switch to 3rd. Just an idea
 
It's never too late to consider methanol injection. :sneaky:

The cost is less than that EvoIII, and when combined with some nice cams it should bump you up quite a bit.

I think 20psi_GST was referring to a ported exhaust manifold, not a new intake manifold. A sheet metal intake manifold would not be a wise investment for your goals.
 
There are a couple vendors on this site that sell them, I believe. I know CoolingMist is one of them. Mine is a Devil's Own, which works very well. SMC kits are a little pricier, but are some of the most trusted.

Just start searching around and you'll find them.
 
Sorry, didnt know you had a manifold already. The hell with the methanol that shit can start problems. Your better off going with just good ole race gas. The hell with all the suggestions.

CHEAPEST WAY FOR 300WHP. 100octane and 25psi. Your set my friend, it will cost you about 20 bucks.

Dont be so cheap, i run ONLY race gas in my beast and i love it, the smell is enough to give you a chubby. Just turn the boost up LOL Thats what youve got the MBC for isnt it?

What the hell you talking about? WTF Meth doesn't lead to problems..Is not like NAWZ. Meth actually reduces gas ex temps and reduces knock plus helps you boost more. Meth isn't dangerous if you are spraying/injecting it to the car. Now if you put meth in your gas tank, then you need that might lead to a problem because meth is corrosive to aluminum but thats why you anodize the fuel rail sense thats the only place that some meth might stay while the car is shut off.

Meth + cams would be a good combo and is cheap. Check out SBR site they are selling Snow Perfomance Stage 1 or 2 kits from 299-399. Oh yeah don't just boost 25psi like that guy said unless you get some studs and headgasket.

Oh yeah, Meth also helped me boost 25psi on 660cc injectors with my 30R without hitting fuel cut :thumb: 445whp baby woooo

ROFL Are you trying to start a flamefest? Your statements are severely misguided. In the long run, a water/methanol injection setup will save you a lot of money while allowing you to run close to a race gas tune on 91 octane. It lowers the air charge temperatures, which is actually good for the engine, not harmful. I don't think we should turn this into a debate about the outcomes of running a meth injection setup, but I can't sit by idly whilst you flagrantly bash something without any supporting evidence.

What i said wasnt meant to start anything. Its just my personal opinion. Everyone ive known thats tried it has not been impressed. Either its not made that much of a difference or its gone fat rich on the dyno, or its been more trouble and money then its worth. You keep running your methanol all day if you like, i dont care. But ill run race gas which is what i prefer. And the cheapest way would be to run 25psi on 100 octane. Im sure if my setup can take 22psi then his small 16g can handle 25 with no problem. And BTW, i never said it was harmful for the engine, just said you can start problems.

I don't want to start anything either, or get off topic. I'm shooting for 300hp like this guy and I'm interested in the meth injection.

Someone said its corrosive to aluminum...
The head is aluminum.
The intake manifold is aluminum.
The pistons are aluminum.
The TB is aluminum.

does anyone else see any long term problems with this..:confused:
 
Besides the water/alcohol injection, which I also advocate, look into cold air intake and a 1g or 60mm 2g throttle body.
 
I dont want to run race gas as stated previously, this is my daily driver. I have run 114 in it before and do like it but only at the track. I know a lot of people using meth inj. and despise race gas, and have no problem with it.
I am working on my cold air set up right now.

Let me rephrase that, yes everything you mention is aluminum but meth is only corrosive if it sits at a certain place for a long time.

If you are injecting meth then you are pretty much spraying a mist into the engine to cool it down and in a matter of a second it will evaporate, so there's no harm to any aluminum not even the head.

Now if your boosting like 45+psi and you are using Meth in your gas tank. Then you need to anodize the fuel rail because there will be some Methanol sitting there and if Meth sits there long enough it would lead to corrosive.

In our case though we are injecting meth + water and it doesn't harm the car at all. The meth injection has to sit in our head for a while to do any damage which would never ever happen, meth injection might not even reach the head cus it would evaporate by the time it gets there, even if it reached the head. Again it has to sit there for a while..But that would never happen. UNLESS you dump meth inside the head while the car is off and leave it there for days LOL

I hope that clear things up.
 
Luis thats right on.

Do you know what brand your friends bought? If they bought some knock off to save cash then it probably was shity, if they spent the cash on a coolingmist set-up, or snow performance set-up they would of had a great experience with it. When a meth injection kit is used it is mostly with a 50/50 water/meth solution. The water helps absorb the heat in the intake manifold charge, and meth gives a boost in octane number, and like Luis said, the meth isnt in the system long enough to corrode anything. The meth also allows the upping of boost on pump gas without seeing any knock. 20psi_GST when you make a claim make sure your clear with it, and your correct, if these meth injection kits didnt work(when not buying knock-offs) people wouldn't buy them, and they wouldn't be saying good things about them.

That makes sence.

Is it complicated to setup or is it as simple as putting a nozzle in the UICP? And what about mixture distribution? Is it just to cool the intake charge or does it actually have to make it to the cylinders. I saw from experience (sea foaming) that the 1G manifold has horrible distribution if something is sprayed in at the TB.
 
No its not complicated, just instal it in the UICP close to the TB. It cools the intake charge and cleans carbon deposits, and keeps the cyls. clean...well as clean as they can get:D Not sure but maybe a bung set-up like for NOS to spray a certain amount of meth/water into each runner seperately. Just a thought of course though.

I bought the Snow Performance stage 2
http://www.slowboyracing.com/shop.p...54&PHPSESSID=e592a4f6bf854805193004afcc326216

Is not a complicated setup, you gotta mount the reservoir (mine is mounted where my stock intercooler sidemount used to be) some use the windshield reservoir because it holds more amount of meth than just 2quarts. Then mount the pump which should be next to the reservoir and connect all the fittings and wirings. After that it comes with this controller that allows you to set at what boost you want the Meth to inject. Ex: I have it set at anything after 8psi for meth to inject. Now whenever you are just cruising you don't waste any meth till you go over 8psi or whatever you set it as.

Is like driving on higher octane but you're not haha. This is why meth is great, it actually helps the car.

I would recommend to do a tuning session right after you install it, because it changes the whole car setup. If is not tuned it can damage the car. Also is very very important that when you tune the car with meth, you always must have meth on the reservoir. Might be a pain to always have to check if your low on Meth but thats a small price to pay for having higher octane and more power. All I do is go to my passenger side bumper and look at my reservoir and if is low i'll fill it up. I don't risk on driving without meth and neither should you if you buy meth because otherwise you're injecting air and well that just leads to problems and BOOM LOL

My mixture is 70%meth - 30% distilled water. Most do it 50/50 but my mixture works for me so thats how I have it setup. It cools down the intake charge and combustion, pretty much helps the engine breathe better. No harm in that. :thumb:

Yeah my intake manifold is helaaaaa clean. Practicly no deposits at all LOL

I've seen my cylinders after using meth for months and they were dirty LOL I guess it doesn't make it that far LOL so like Dustin said, as clean as they can get LOL

I just have one nozzle fitting but I have seen 4 nozzles injected in each runner and it looks badass :thumb: but i'm just fine with one
 
For anyone about to install a meth injection setup, I've been tossing around the idea of doing a writeup for a trunk install. That is how mine is set up. I already have all the pictures necessary to make it; if there's enough interest (and it hasn't already been done on here) I'll go through with it.

I would love to see that write up. I just purchased the same meth kit you have and want to mount it in the trunk since I dont carry my spare or anything in there.
