Are you talking about things like raising the boost, letting is breathe more easily, or advancing the timing? All very cheap and will yield good results if done correctly.

It depends which EJ20, you gotta be careful with the STi v5 motors, due to the higher compression, they are less susceptible to tuning.

Just let it breathe easier, filter, exhaust. I would go with a chip unless you knew other folks with the same engine doing the same thing and not having any problems with it.

There have been many reports of recent EJ20s blowing up over across the pond.

We are nothing
without our founder.


This is a race-only mod! But, it's cheap, easy, and effective.

1. Get some aluminum screening and a hose clamp.

2. Take the air box and piping off the turbo inlet.

3. Cut a square (or circle, whatever) of screening to fit over the turbo inlet plus about an inch or so more.

4. Secure the screening to the turbo inlet using the hose clamp.

5. Wallow in the glory of making a cheap full-race intake for your turbo that will make lots (?) of power but still protect the turbine!

I've seen a couple of DSM guys do this with their turbos and they said that the power gains were extraordinary because the factory airbox was so resrictive.

**Warning What you are about to read is a Joke and is not to be taken seriously**
Getting the most out of your Honda Civic or Acura Integra

Wanna add 150-250 extra horses to your 1.6 or 1.8 liter Honda? I know you do so
I'll share my wealth of knowledge about cars with you.

Stage 1 (15 -30hp)
Take out your spark plugs and get some Bosch 4 tip platinums, the coldest
range you can find, then sand the 4 tips so they are rounded and smoothed
then bend them towards the center as far as you can without touching. Dip
them in alcohol to clean and reinstall! Before reinstalling pour 30 ml of
mineral spirits down each hole followed by an once of Castrol Synthetic
fuel injector treatment and start her up!

Stage 2 (40 - 70hp)
Remove your cam shaft(s) from the engine clean in alcohol. Some would get new
ones or regrinds, ITS A WASTE OF MONEY, do it yourself. Get some sander and
take off 1 mm all around thus shorting lobe duration. Then polish it to a
shiny finish and reinstall! Pour an ounce of Castrol syntec before closing it
off. Start it up and listen to the engine sound, it may sound very rough and
may stall, but don't worry once the revs build up you'll hear and feel the
engine working harder than ever!

Stage 3 (95 - 195HP!!! not for the faint of heart)
Basically its a homemade turbocharger. Go to your local hardware and get
the best leaf blower you can find the more power the better. Remove your air
box and filter starting from the throttle body and back attach your intake
(cold air intakes work the best) to the air intake on the leaf blower use
duct tape to seal it. Disregard your air box, but take the piping from it to
the throttle body and attach to the air blower on the leaf blower and then
to the throttle body use lots of duct tape to ensure a good seal. Take the
wire for the leaf blower splice it and attach to your battery. An option is to get a
12V cigarette lighter plug to 120V standard household current adapter. This way
you won't have to bother with relays, etc. Make sure you don't use the air
conditioner while running it. Some creative people create there own on/off
switch. Start her up. No spooling time required instant 9-17 psi of boost

Other notable tips:

-unless you regularly travel at speeds over 120mph then downforce is your
enemy despite what has been shown on this writeup. lift is good it makes the car
lighter! The lighter the car the faster it will be!!!

-Mix paint cleaner called Xeloyne (get it at any hardware store for a few
dollars) Add it to your tank and get a boost of octane of 20-30 points. Do
not use in more than 1-5 ratios.

Just by the sound of the engine I figure 1/4ml times deep in the nines.
And the thick black smoke coming from the exhaust is from the Xeloyne
in my fuel it really cleaned out all the carbon deposits!!!!!! Play hard, drive fast!

oh yeah disclaimer here,... i'm not responsible if you blow up you car or anything
so please try at your own risk
Got this off my friends page...

Edit- added smiles and a disclaimer
