[OzzRocker1]

hi guys i just bought a vb as my first car im slowly doing it up as i am new to it all so far i have re done the inteirior it is now a black and silver i have put in a new stereo and bolted on a new steering wheel and im still tossing up between and SL/E paint job(white) or goin with the same sle idea but the main color being black and the trim being silver. Im about to get a new exaust system put in (nothing too flash) and i was hoping some one with some experience with the 202s could help with some advice and recomendations on mods to make it go faster ... my mate has an au falcon and i want to see his smug little face turn to tears in my rear veiw as i hammer past him lol
thanks guys

Unfortunatly your not going to have your mate looking in your rear view mirror without big dollars, unless he cracks another head or you mess with his car first lol.

What I would do, keeping cost in mind.
Would be run a Vk EFI Head and EFI setup, a nice cam, 2 and 1/4 inch exhaust/EFI extractors, thermo fans. Have a look on oldholden.com if your interested in the EFI setup as there is some guru's there can help you out on a budget.

Otherwise, a 12port blue head, a 34adm weber carby, extractors, 2 and a 1/4 inch exhaust, shoudl help it breath better. Depending how far you want to go, but cam, porting, etc if your prepared, also do u want any sort of fuel economy?

Also if your looking for an off the line race (legal) then look at diff gears to give you a bit mroe get up and go.

You should be able to pick up a cheap EFI setup for under 200 bux, or look at buying aVk EFI wreck, grabbing the gear off it and selling the wreck you should be able to atleast break even.
The main note Ill add is that a blue/black head is not a direct bolt on ot the red block, you need to redrill some water jackets in your block using the blue/black gasket as a template.
Im not to sure gearbox wise hopefully Scott will see this thread and help you out aswell. But I think you owuld have an M20/21 box which would have to be the stronger of the 4-speed boxes, You could always look int a 5-speec conversion, either using the standard 5 speed which isnt the strongest, or a T-5 or Celica 5-speed conversion.

There was something wrong with the AU's you raced if thats the case.
VB Commy - stock 71kw and around 1200kg's (from memory)
Au Falcon - stcok 157kW at 1500kgs.
Not to mention the better technology in the falcon. Dont get me wrong I love the Holden six, but im also in a state of reality about it to.

The 350 Holley is a pathetic carb, we all know that. Its a race carb, it drinks petrol like theres no tomorow, and caus of this you get terrible flat spots. A 2 barrel Progressive carb is a whole lot better, because it has smoother fuel delivery and also can deliver great fuel economy being a progressive carb.
A Cam will bring any holden 6 alive though.

[leigh 7005]

just to mention the au was an auto and the holley was great on my engine also have you ever driven an au they are crap i had a ea falcon with el injection and five speed and draged my mates au xr6 and i was running on 5 cyl they are crap and look like pasties lol

I dont want to admit this, but the auto in the AU is a bloody good box, apparently its the same box used by Maseratti on earlier models. In a straight line the auto will always be quicker.
No I havent driven an Au, but have been in one and they definitly wernt a slug, not a powerhouse though. I agree there ugly as a nuns coot, but there more aero-dynamic then a vb if we are comparing them in a race.

Its definitly possible to beat a Au, but its gonna cost some dollars. The only hope you have is if he cant drive for shit lol.

Being that we are dealing with a VB with a red motor it will take any V8 donar and its pre pollution so mods are nearly endless.

I would seriously start looking for a written off, rooted etc second hand V8 HQ, HZ, HJ or VB commodore with 5L running gear take out the engine & gearbox other odds & ended out needed for the conversion and sell the wreak off for other spares.

The money you spend modding a 202 a standard V8 will still put out way more torque & the same or more power.

cheers

[leigh 7005]

just to let you know my ea is the only ford i have owned but it was a very quick car had a drag with a new monaro it had a sticker on it 275rwkw and i was a car length behind him all the way not bad for a crusty ea but ill never buy one again.lol

i would be going v8 as well unless moneys not an issue.

But thats what im saying for the same moneyyou spend hotting up the 202 you could have an 8 in the car the old red 5L engines are going very cheap now. By the time you spend money on a cam, EFI, extractors gearbox conversion etc your pretty well spending the same money to do the V8 with gearbox anyway.

Agreed, unless hes governed by P-plate laws, which was my initial guess. an 8 hands down is the cheapest/simplest way but it depends if he was planning to go that extent aswell. Everyone wants a fast car, but no one wants to put in the effort lol.

[OzzRocker1]

hi guys thanks for all the help i am curently bidding on a VK efi setup and comp and i am also bidding on a stainless steel set of extractors and sadly i am held back by stupid p plate laws but i am allready planning and saving for a hz,hq,hj panel van to do up as a show van but as i am still learning i figured the vb was the way to go
thanks guys

[vkberlina]

Buy a written off EFI VK dont buy an EFI conversion as you will need too many parts
Head & block are different red to black Dont buy the extractors the EFI VKs come standard with a really good set of extractors. Plus the red motor ports are differently layed out to a black motor for EFI.
Rebuild the 202 40thou pistons, mild cam, port the hell out of the head and you will have a pretty good 202.
You will need fuel lines, fuel tank fair bit of wiring from the doner VK.

Also stainless cracks easily your best with mild steel exhaust and have your extractors ceramic coated it will look like polished aluminium when done.

cheers
Scott

[OzzRocker1]

thanks mate
i have allready bought an efi its complete less the computer and i payed 50 bucks for it all
i have allso allready bought some oem grade stainless steel extractors that i payed $200 for
im not too familliar with EFI setups so im going to read up on it and see how to set it up after i bolt it on
thanks

KC

[Tom_1569]

The EFI and Carby extractors are different, but I think they can still be used, aslong as they are 12 port Extractors.
As Scott said its easy to buy a wreck, as you will need a lot of parts.

Everything from the Head upwards, Computer, Wiring, Fuel tank and pump, return fuel lines.
Depending how much you want to go, maybe looking at doing work to the head before you fit it, and find a nice cam.

[OzzRocker1]

wont the fuel tank on the car be good enought to run the EFI and the extractors are 12 port
thanks

Yes and No.

The EFI needs an electronic fuel pump, and the return fuel line. Since the VK tank bolts it, its the easiest option. You could modify your tank for the return fuel line and plenty of people have done so, and you can run an external electronic fuel pump. Just depends how much you want to muck around, using the VK EFI tank is just simplest option.

[vkberlina]

DOnt forget if he is using the red 202 block he will need to drill holes in the black head for the water galleries, from memory there are 4 that need to be drilled. You use a black motor head gasket as a template.

If the extractors he bought are for a 9 port head they will be useless and he will need to buy a set for a 12 port head.

cheers
Scott

[OzzRocker1]

they are 12 port extractors

[OzzRocker1]

will i need to get a black motor head if my red motor head is the 12 port head and how do i tell if it is a 12 port head?
thanks guys

KC

[vkberlina]

Heres a pic of my old 202.
The 12 Port head has 12 ports 6 inlet 6 exhaust
The 9 port heads have 3 inlet & 6 exhaust

I dont have a 9 port head pic to show you the difference maybe someone else here has a 9 port head pic

cheers
Scott

[OzzRocker1]

Hi guys
i was wondering if someone could tell me the differences in a black and a red 202 because im trying to figure out wat mine is...i know that sounds silly lol but the original red 202 in the vb sl came out with auto trans it had a single barrel stromberg carby and mine has a manual m21 trans it has a varrajet 2 carby and it has the 4 bolt patern on the side for i think its either power steering or aircon and i dont know if it helps determine if its 12 or 9 port but i took the rocker cover off today to respray it and it has 12 rocker arms
thanks guys

KC

[Cane_It]

look in the ports, a 12 port has each port properly divided, a nine port has siamese intake ports, ie there's a cast iron column (where the headbolts go through) in the middle of each intake port.
like everyone else says, buy a written off VK EFI, that way all the fiddly little bits you can swap over, rather than paying and scrounging wreckers to find odd bits. You can then swap the fuel lines, fuel tank etc straight over, sell the rest and get some money back on it.

[OzzRocker1]
