cheapest HP improvements for under $500
 

Hi, My wife runs the car daily to n from work, and I get to drive it when we go out for dinner with friends etc...

What I'm wanting to do is a simple few tweeks to the bog stock standard 86 (all at once whilst the misses doesn't know) include

Perrin Crank Pulley (majority of weight saving is here so can't justify the extra expense for the set)

K&N/ Perrin air filter for stock air box (30% less resistance to standard flow)

My own forced air induction system designed and installed using house hold plastics and tools

Exhaust tape for Headers and mid Pipe etc...

has anyone got any more cheap ways to increase HP... regards Pete... PS my first attempt at posting...

you say household plastics... all i see is an 86 with this...

Hey thanks Supra,, I hadn't thought to use PVC pipe?!? Wonder if it comes in black lol

How are you going to make a forced induction system out of household plastics?

Rotate your distributor to advance the timing a bit..oh wait, it's 2013. There is no cheap horsepower for NA cars anymore.

I'd look into one of those Open Tablet whirlygigs or one of those BRZEdits if you want a noticeable improvement for under $500.

Turbonator comes in awesome colors now.

many ways to do this... all is required is to direct Cooler air from in front of the Radiator...using Kiwi Know how!! will post pics once it has been done.. Buy redirecting air flow away from the Radiator and into the ram air will not be hard..

Forced induction on naturally aspirated engines will pretty much increase volumetric efficiency to 100%

What is going on tonight with these thread!

Do you even know what forced induction is?

TireMonkey, You have little to contribute and looking at your past posts and you don't have much to contribute other than correcting peoples terminology of words... I used the term loosely to explain Ram Air...

At speeds faster than 30kph any redirected Air into a standard air box will in its self be Forced induction as any Motorcyclist will understand?

What engine improvements have you done on your Car that increased HP through slight changes? I'm suspecting very few for a lot of Dollars? which in terms of HPx$ was very expensive!!

A) Thanks for stalking me but your assumptions about my contribution to this forum are false. Also when people use the term forced induction around this forum they usually mean super/turbo charger. Which is why I was wondering how you were going to accomplish this with "household plastics".

B) I never said anything about my engine improvements or that my car was better than anybody else's. If you really want to know what I have done to my vehicle then check my garage. You probly should have done that while you were stalking me.

C) You probly shouldn't criticize others about contribution to a forum when you only have 11 posts.

Twin Leaf Blowers = Twin TURBO!!!!!!! :burnrubber:

jk

This would have been true 30 years ago but now everything is controlled via the ECU and MAF sensor. It isn't as easy as just blowing more air through the intake using homemade plumbing. Good luck with the trolling and all.

Yea Ive been planning on making a turbo out of my vacuum, I estimate 80-120 Hp improvement at only " medium " height floor setting. It's a Dyson so I can only assume it's gunna be just as, or more reliable than a stock turbo if it ever came out.

Next I plan on making a set of coil overs for under $50 using high grade slinkies, stay tuned!


Op was trolling right? Lol

I whole-heartedly second this statement.

I had a buddy try to run "bare floor" on his civic with stock internals. He ran low 11's for about 30 minutes, but then...

Nothing under $500 ,the parts r too expensive for the twins lol

I am thinking there are tons of sarcastic recommendations for the OP.

Cardboard Rocket Bunny kit +50 WHP. Add a rice cooker to the intake

Previous poster, I one up your idea using a central vac. No more old school upright Hoover, that was so last week.

Lmao, remember people, always empty the bag before installation!

Ugh. Where were you that day? Could've saved a lot of heartache.

Back to the OP, in your price range probably the single best thing you can do is to install a Unichip on it. I have one, and although I haven't had it on a dyno, my impression is that there is a noticeable gain in HP and torque. The torque dip is not nearly as noticeable as it was before the Unichip.

Get the open flash tablet ecu mod. Nothing else will give you the same results for 495.

I agree with this. It's hands down the best power upgrade you can do for under $500. It's easy to install, invisible for warranty work and you can update maps for future mods for free. The increase in midrange torque is very noticable and the engine has raspy growl to it now. If you have a few extra bucks add a drop in air filter to complete the set up.

I mean, you wont get massive gains but...

Let me make it simple for you. If you want just HP review the forced induction section and read up on the electric supercharger, $1,700 estimated pricing for the kit. Currently, I am one a 3 US testers and below is my dyno of unit performed by Drift Office.

When you say invisible to warranty I'm guessing you flash it back to stock when you send it in for work?

Correct. This is from the Vishnu OFT product page:

"Is a flash from this device detectable by the dealership?
Each modified ROM file is based upon the original ROM. In this ROM file, you have all the mapping data and the software ID data. Typically, you will only ever want to modify the mapping data. Which means the software IDs will be untouched and stock-looking upon basic inspection. However, it is possible for the dealership to conduct a more thorough inspection of the DME code. Which is why we recommend flashing the original ROM file back into the DME at your own discretion."

im surprised no one has talked about the visconti fuel kit, it gives some hp and its in that price range....

How the fuck did this thread get archived into the DIY section?

I could have done more good walking around home fucking depot taking photos of shit i can screw onto my car with self tappers.

I agree with this as well

The best way to create power in your budget range is to re-circulate the exhaust into the intake; and since you are such a big fan of household plastics, you will love the simplicity. This is how all of the honda guys are sh*ting on all the exotic cars at the drag strip.
connect two pieces of flexible 2.5 inch piping to your exhaust, then use a plastic PVC Y pipe and connect them. Now run a long piece of PVC pipe to the front of the car. You might need to connect it underneath with Zip ties or Duct tape. IMHO the pink duct tape looks the best.
Now once you have the pipe at the front, start the car and take a big breath of air out of the pipe to mke sure you installed it correctly. Now connect another piece of flexible piping from the long piece underneath, secure it with a hose clamp as you will have so much boost you might pop it off!
Connect the flexible piping to your intake snorkle under your bumper.
Now your car is pretty much a ram jet and your wife and you will have so much pOOWWWAAA you wont know what to do with it!!!!

intake ~250
pulley kit ~250

or

save 100 more for ecutek tune 600

FREE / CHEAP MODS
1 Cap the intake and delete the sound tube.
not sure if it actually does anything (some people say it makes a tiny difference)

2 Mod the stock stock snorkle. drill out 2 rivets. 1 on each resonator. remove the resonators. then cut off the 2 pieces that stick out. fill the 2 holes with plastic and epoxy to close off. at the turn (the long part) cut the front and using a heat gun bend the bottom. then use plastic and epoxy to close off the side(the original inlet). then fill the front, bottom and other side to close it off leaving a large opening in the front right behind the grill to create a ram air kind of effect. which probably wont have much of a ram air effect but in theory it should and it will defiantly help get colder air to the intake.

Agree as well.
It's right at your price range and really improves your car.
