just chasing some information on stroking a blue 202. as in cost, reliability, performance, rough power out put. thanks!
from memory they were using modified ford cranks, cost, huge for the small gains. perfomance.. what with a 202?? power... what with a 202??? much better throwing your money are better engines.

Off hand I believe a mob called Pro Stroke makes a stoker kit for the 202. All up I say with all machine costs/parts etc you could be looking at 5 grand plus .Results I could not tell you but it would be a diffrent way to go then the traditional v8 route.
There's a place called bryant engineering "google it!". They do stroker kits for the 202 which throws the engine at near 250 Cu.i. Read up on it a few years ago. They use something like Short SS pistons, A ford crank and hemi-rods. Don't quote me on it, but the kit used to cost around $2500 which isn't too bad really. I think it comes with one of their sumps also. Personally, if it was me i'd just get the standard 202 , work the guts out of it, mass port a head and throw on a set of triples and get everyone looking. Don't worry about people saying a 202 is underpowered because mine is certainly not!. These comments are usually from ignorant people with no real knowledge of the engine and its potential. 300Kw+ is quite easily achievable and isn't lacking in power whatsoever. My 6 leaves most 8's for dead as I have done so. The old man used to build and race 186 red's back in the day with his race cams and triples and thought they were beaut! "I was just a toddler back then!". But when I built my bored-out 3.3 blue and we put on the triples he took it for a test around the block and said he'd never drive in it again!!. Way too much of a scare for him, and I drive on pure adrenalin.
Cheers Mate!
riiiiight.......lol, i certainly hope you have some form of proof to you 300kw claim. to prove us "ignorant people" wrong
so your saying that you can get 2.2 VE from a 202 N/A? just by boring it out and sticking triple webbers on? jesus, i wonder why holden dropped the 202? seems like a silly thing to do if you can squeeze that many horses out of a 6. my V8 is pushing around .9 VE at the mo.
Ford crank, Hemi pistons, bored ported etc etc, at what point does cease to be a Holden 202??
Was there sarcasm in his voice?
I have had some pretty wild 202s including a CAPA blown, many N/A, and they dont come close to a V8 for $ for $ spent. The only time a 202 would get me close to being excited is in a Mk VII Bolwell and thats in a car weighing around 800kg. As for 300kw+ how long would that last for before it blew up I ran 12PSI on my 202 and didnt come close to those figures.
What DerekP said is the original stroker for the 202 but seriously why bother they are better power gains to be had for cheaper, with better drivability and fuel economy the 202 should have stayed in the 1970s.

hmmmm maybe he cant drive a v8 and wants to build a 6 and why go on about money you dicks it aint yours he is going to spend so why not just help him out rather then flaming him over the net with shit
i am currently doing a holden vh project it has a blue 202 and i have hq racing extractors 186 head so far which arnt on it yet but do the 202 up man they sound ****en sick when they have work done to them
heres wat i have already done. 40 thou over, 38/78 cam, reco head shaved n ported. 350 holley, extractors, msd ignition, regraphed dizzy it idles really lumpy revs hard as goes ok, it only has 100 hp at the wheels. it sat side by side with a vn v6 once (which impressed me), i just want to keep it n/a for now but also gain the most performance possible.
yeah, itll be a fun engine. i cant stress enough how much i love roller rockers so if you ever find the cash go swap em' over. but please dont listen to big horsepower claims like "300KW" cos' they are just not true. not flaming anyone, not criticising, just think that some people need to really understand how engines work and what power they can expect.
Come now Ari - Maybe our friend slayer is a little over enthused with his figures, but you can't write the old six off completely. Holden dropped the 202 for two reasons - emissions regulations, and the amount of money it would cost to redevelop it to meet them. Bit of a shame really, I reckon it would have been good if holden had of kept on with an aussie straight six, like ford.
Just wondering, what does VE mean? I googled it and found nothing.

VE = volumetric efficiency pretty sure, seriously tho u can get good power out of the holden 6's, i spent 4 grand on a 186 (now a 208) for the vh...it went hard but u can do so much better 4 that price, could have done a 304 or 308 conversion or rb30et conversion. all are easy and cheap to do if u can do it urself
How To Build A High-Performance Holden Six
for the knockers read the first part of Characteristics and Limitations
Thats true, you can of course get more for your dollars, but as much as I love the v8s, its a pretty common conversion. I like the v6 conversions as well, but I just love the old straight six. Its hauled a lot of people a lot of k's around this country over the years. And because so many people knock them, it would be cool to have one that went hard. And I hate rb30's with a passion. I'm sure there's a special circle in hell reserved for those who put rb30's in anything pre vl. Or indeed after vl.

lol, although i read the article (well, most of it) i still dont believe it. i prefer to believe wikipedia: "Volumetric efficiencies above 100% can be reached by using forced induction such as supercharging or turbocharging. With proper tuning, volumetric efficiencies above 100% can also be reached by naturally-aspirated engines. The limit for naturally-aspirated engines is about 137%[1]; these engines are typically of a DOHC layout with four valves per cylinder."
and yeah by VE i meant volumetric efficiency. i.e. 300kw, being 430hp, 202 cubes = 2.12 (my maths sucks btw) that is a HUGE figure. im not saying you cant make a powerhouse, i am just stopping the guy from getting his dreams up, only ti have them dashed when he does his first dyno run.
