202 advice.

[eggle]

gday, im lookin to do up a 202 blue or black motor and was wondering what stores around ipswich/brisbane area would help with the modifications? being the first time modifying an engine i have little to no idea where to start.

can i just ask a mechanic to do work on an engine for me? or do i have to buy parts and then have them put on?

also can anyone give me a rough price of working a 202 (cam, head, holley, headers, exhaust, good block.)

A performance 202 will not be cheap. Cheap compared with a V8 but still costly.While there are plenty of parts around at good prices if you don't have the know how to throw it together the labour involved from the mechanic will blow the price out.
Look for a 202 for sale as a complete engine which has already had the work done, i.e. yella terra head, YT rockers, flat top pistons, steel crank etc. This will save you a heap on building it yourself. Buying 2nd hand
you'll still be up for $2000 - $4500 for that engine but thats cheap considering the cost of building one to that performance level.
Talk to people who have built hot 202's before as they'll be able to tell you the do's and don'ts with first hand knowledge.
Can't help with mechanics up your way sorry.
Good Luck with it.

the dont is "dont do it"

Do up a 186 instead, they rev higher and produce more torque. Paint it blue, cable tie some hoses around it, police probably won't know any different.

gday im new to the forum, today i bought a VH commodore (my first car) which has a blue motor, it has a burnt out valve in the 5th cylinder(not my fault), I was wondering (since we are on the topic of doing up 202's) does anyone know how much a stainless steel or titanium valve set will cost, im not looking for installation cost either because i can do that myself. I seen a Red motor once for $50. those are good for first timers

actually 202's make more torque due to having a longer stroke

and blue motors also has xu1 style conrods and a counter weighted crank

[Not_An_Abba_Fan]

The torque curve is sharper then, they rev quicker and get to maximum torque faster. They produce the torque better than the 202 is what I should have said.

[Trav001]

the blue motor in my VH idles at about 500rpm, im told thats good.

I'd use the black 202 over a 186. Superior bottom end and the black head is comparable to the old 9 port stage three yella terra.

The best bang for buck is forced induction, ie. supercharging.
The Toyota blower setup from the Castlemaine rodshop (though others are doing it now as well) is a great deal at around $1800.
I'd include a stroker kit from bryant engineering, you supply the black crank, and it takes out your 202 to 249. Its a complete kit using hemi rods new quality pistons, bearings etc for $2000.
With just a mild cam this combination pulls like a train throughout the rev range. ie, no need to flog its tits off.

Those chargers from crs wont keep up with a 3.3L engine and also the charger is mounted upside down

your best beat is the turbo route buy a complete garrett strata kit and have some fun with that if you want to go efi you will need everything custom made and the intake manifold will let the whole setup down

Stoke it are you talking about a modified ford 221 crank? if so they only stroke it to 234

[FCCOOL]

what are you pepared to spend.
black is the best but it has nasty smog gear witch should be hooked up to be legal, the oldest you can go in a VH is a blue motor(173 or 202)
if you want a mild hottie read the street machine grunt hunt.
Advantages of a red are a lighter crank that can spin up quicker and less or no smog crap.
The lighter crank is also a disadvantage as it isnt as smooth without counterweights.
if you cant build any of the motor you should try and find a fresh hottie for sale.
i spent 5k at the engine shop on my holden six and still have to put it together, i also supplied alot of parts on top of that so if you want it to be fast you need to save hard, with the availabillity of cheap factory v8 commodores it isnt really worth it, maybe if it was a LC-LJ or something earlier it would be worth it.
you can also get efi 3.3's for around $300 now.

[Dose Pipe]

Like above it costs alot of money to build holden 6's with absolute no gain out of it there old motors and cost way to much to build but if i was to build one it would be

stroked
twin cam
blown (big gm blower)

[Dan355]

As said. A holden six is **** easy to build. Machining is cheap so are the parts. If you have the know how it's far worth it then a conversion but at the end of the day nothing replaces cubes! I have to say tho you get a better feeling raping the arse off a 5ltr with a 20+ yr old 3.3ltr straight six

[grantisaac]

Mate,If you want a basic setup for a daily driver and remain reliable have the block bored and fit a set of ACL Race Series Pistons as fitted to the HQ racers.Find a secondhand yella terra head and use a mild cam with extractors.This will give better throttle response and a gain in power over standard without going overboard.
