Adding Power?
Hey,
Just wondering if anyone could give me some tips on how to add power to a 202 at resonable costs?
cheers
Carpark Mechanic.....
We need more info mate...
Like how far are you willing to take the engine, Like stroke it, boost or what?
And what is "reasonable" in your eyes?

Get yourself a set of extractors, a single 2.25" system with a good quality muffler.
Hunt around for a Redline torquer 2 intake manifold and a 350holley (there will be people on here with a dozen other suggestions, Webers from a Falcon for one. The 350holley is the EASIEST and cheapest carb to use, best bang for buck as well. Anyone who argues that is a muppet).
Upgrade to an electric distributor and make sure the rest of the ignition system is in good order.
Change to a twelve port head, if you don't already have one (Only the red motors don't have them).
Upgrade the cam, which cam will totally depend on what you want to do. When you do the cam, remember you'll need to do the rest of the valve train at the same time (short of valves obviously). Personally I like to use timing gears, but its been a number of years since I played with a 202. So there may well be better products on the market.
Look into roller rockers as well, I'm not sure if they're availible, but if they are its definatly worth looking into.
After you get this far you're looking at rebuilding the motor. Which is essentially the point where you buy a 308.
For the record, its not feasible to stroke a 202.
It is possible to get an intake manifold to suit a 4/71 supercharger, I wouldn't do so with the factory bottom end.
Turbo charging is dificult with a carbied 202, and not worth the effort In my personal opinion (They can make good power, but the constant head aches make it not worth while. Been there done that. We made 317bhp@17psi before we lifted the top off a piston, it lasted 4 months, give or take a week.)
If you're really keen, you could go EFI. DO NOT use the factory setup. There are many generic fuel injection systems on the market. Most all of which are far superior to the 27yr old ancient history of a system that holden used in 1986. The only useful item maybe the EFI intake manifold.
well not as far as boost or anything, and probaby around $3000
yeah its got pacemaker extractors with a 3inch right through... i think thats all thats done to it, besides the triple carbs...
This is my first project car, im 17 so im still learning hahaha take it easy

Take ther 3" exhaust and throw it over your left shoulder. Its too big for the 202.
Failing that read my last post.
:):):)
sorry it has a 2.5 inch exhaust on it, checked it today, the guy whole sold it to me didnt know what he was talking about, and my fault for not checking...
anything else you can add and stay within my budget?

I just told you the best way to go about it. What more do you want?
okay thank you.. um for what you told me, do you know what that would roughly total in price?
Banned
It all varies.
Intake manifold and carby might set you back $500 depending if you get a new carb or second hand. 350 holleys are a dime a dozen.

Redline torquer 2 intake manifold and a 320holley economiser.... much better on fuel for general driving, but put your foot down and it will dump 1and half cups of fuel down the manifold.....
We put a 186 head on our 202, bored the thing out to 210, pacemaker extractors, redline intake manifold and a holley 465 carb. straight cut cam gears, v8 trans.
Check out my build <---Click me
Now sporting ASR audio interior lighting and stereo mods, and MACE induction mods.
Need your computer tuned, or dash calibrated??? Want your PS3 fixed, or wish to prevent the YLOD?
thankyou soop
sp001in, do you know the horsepower that 202 made? and costs?
Banned
HR 202 was about 130hp@fly wheel.

It cost me $800 to have my old 202 bored out and machined. I had it bored out 30thou, dunno what that equates to.
i ment sp001in's motor... the 210?
and the costs for what he suggested?
Banned
210ci will probably just be achieved by boring the cylinders out.
Why did you delete your last post?
ohhk, yeah cause im only just staring out on this car, this is my first project, i paid 5500 for it, and its got a recon 202 in it, with 6000kms on it, so im looking for easy and cheap ways to add horsepower...
cause i think i repeated myself, my computer glitch... hahaha

well if its reco'd don't go pulling it apart to get an extra 8 cubic inches. It won't do anything.
My initial post has just about all the information you need to make a start.
okay cool, thanks for the info, ill search around for parts.. any advice on where to look or anything?
is it worth putting a lumpy cam in it?
Banned
Well I did mention doing a cam in my initial post.
It is worth doing. Provided you use the correct cam.
yeah i know you mentioned it, but is is worth putting a lumpy or more of a mild cam?
Banned
Totally depends on what you're wanting to do mate.
You'll need to find out whether or not its got standard static compression before you go making up your mind with a cam.
Im building a VK brock replica and i was going to get a 308 in it but due to the new P plate laws i have to keep with the old 202, so im working it. So far i have done pacemaker extractors 2.25" and sports exhaust system, Redline torquer 2 intake manifold with a 450 holley carby set up, redone valve springs, new belt kit, new mild cam, timing gears and roller rockers all up it has set me back around $1500 (doing most of the work my self with mates help) and now shes running like a dream. With those extractors it sounds like a 308 any way.
If it aint Holden it aint shit!
