202 Turbo

[NVE_069]

just come across this vh 202 turbo. thought id post it up for u guys, i dont think i have seen anything like it.

cheers

[Shifty1]

I fail to see it..

Guys at work are encouragin me to turbo the vk but im not rich.. how much does a turbo go for anyway?

[Boonz]

that seems to be a bit pointless........i think that the engine is too small to have a turbo whacked on there....jus doesnt seem right

yer i was thinkin to turbo my 202 but i didnt have any idea if there would be a point to do so.

ul find turbo kits coming around here and there, the first motor i did up for the vk was a turbo 202, rebuilt a stock motor, decomp plate the head and bought a 2nd hand turbo kit with recoed turbo for 1800 with all the plumbing, carbie (twin su's) and modified sump. went very very well say and had beaten a most efi v8s (5.0l vn onwards) the only problem with these kits is that they can be very limited and because there a carbie draw through setuip theres really no provision for intercooler etc, where water injection to cool intake temps was the only way to stop it from knocking on boost at high revs. the main problems was to get the power to the ground, 1 clutch in 15,000ks was not very good, and the aussie 4 speed was very very tired after this time too.. alot of torque with these setups. it will rev to around 5000 very easily but lack after that with boost starting around 1800-2000rpm. the motor in the end did not fair up to well i got about 25,000ks out of before i lost compression on number 5 cyl. You really need to spend some big dollars to get it realiable and perform well. a full recondition of the motor should be in order, cast pistons are ok go for hypereutectic around stock compression ratio. pref forged pistons with around 8:1 compression ratio. a vh electronic dizzy worked great and i did not have that regraphed to suit turbo cam, woulda been better if i did. so all up to get a fairly decent 202 setup with fresh internals around $3000 diy, 3500 with forged pistons, but if u get someone to do it , wouldnt get much change from $5k. id say after all that money an rb25det with manual r33 box is a better way to go, front cuts around $2500 with mods to mounts, tailshaft, odds and ends and eng cert should get away with 5k, and will have about the same power as the turbo 202. good thing with the rb25det is that it is very modifyable with alot of power to boot before reliablitly is gambled.

overall, the turbo 202 is a weekend thrasher, would not go day to day driving with it!, but if u go thru it all its fun to have. i do not have the motor in car now, i sold off the whole tired motor + including turbo gear (exc cond.) for about 1500 which then payed for the engine i have now, so it hasnt been all lost.

il try n find sum pics around.

cheers cam

mate an off its head 202 is a pig of a thing to drive and guzzles fuel like an F truck towing a horse float. It all depends on what you want, from the car if you want tyre shredding fun install an 8, if you want to drive in all day long and not worry you might think about a V6 from a Vn-Vs goes as well as a 308 but heaps cheaper to run and still have six cylinder rego. If you like turbo's you could put the VL turbo motor in that would be tricked and it would get up and go. good luck mate sick vk's are rare these days good to see its not just me still interested in them

good luck mate sick vk's are rare these days

check this vk out then... is owned by my nan THE VK....

Now this is a real turbo 202.
370Kw And 10 seconds

[Boonz]

WHOA!!!!! 126 MPH out of a 4 speed toploader!!! thats crazy haha

[ECILOPX]

Here are some pics i found in a old book, only thing is it`s a 186 not a 202.. Still shows that it can be done Nice sleeper too i rekon

[walesy]

check this vk out then... is owned by my nan THE VK....

Jon

your nan is tops

[scorpion_989]

check this vk out then... is owned by my nan THE VK....

Jon

thats shit is sick

[GiantCan]

I was going to but a 5.0L Torana as well. It was in pieces, but still... 5.0L...

[Fat VB]

im currently working on turboing a vk with a 202 and its workin out to be rather cheap

[mullet]

Cool that's what i want to do with my VK eventually....

But first i want to get rid of the Damn 3 speed Auto! There is a guy down here in Tassie apparently that imports 5 speed Supra gearboxes with all/most of the gear you need to put it in.

i have just done a vk 3spd auto to a supra 5spd turbo box. best thing i ever done would of cost me heaps but i got mates rates! but castle main rod shop does the standard supra box with the 202 bell housing kits. not sure how much though!


i've been thinking of a turbo, like i'd only be wanting 6 to 8 psi boost, my bro has a tc06 i could use but i dont know if it would be big enough or if its even worth it, i've herd the 202 black has a rather soft block and wouldn't handel it??

[holden#1]

don't know how many of you are aware but they built a few factory VC Commodores with a turbo. I remember reading the write up in wheels... 130kw!!! they reckon it was great for towing; a total rocket etc, etc... old Peter Robinson was wrapped...

[Sammy]

wow, that commodore musn't be running much boost, 140hp at the wheels is 8hp more than my EFI 202 makes without a turbo!

as for the castlemaine rod shop kits, supra kit for my mates HR was $1800 delivered, everything we needed from diff to flywheel

[holden#1]

I don't think they made many cause I never seen one...

[vn25det]

hdt made turbo vc's i cant find the link to it at the moment but when i do ill post it up. they stopped making them due to the heating problems that they couldnt overcome. they were a upgraded version that was released on the uc torries
few links on the uc but relivent for the commy

HDT didn't make VC/VH turbos, that was CDT, Country Dealer Team. CDT are nothing to do with HDT at all.

[Goon]

Wouldnt mind gettig my hands on a turbo for my 202

With that issue vn25det i think that would be solved after so many years

my bad bro i did have country in head but i was thinking of they were optioned with a country pack lol but ty for joulting my memory yes it was cdt not hdt lol

IMHO, the fact that the carby sat infront of the turbo intake they were doomed from the start in my mind i have never liked the set-up and never will.
only way to go is a custom mani using the vk efi head as they r a far superior flowing head over the red/blue heads, using the efi intake with 32lb injectors. and having a properly built bottom end and not using a decomp plate as that will cause overheating low compression ratio regardless of whether from decomp plate or low comp pistons means lower thermodynamic efficiency so more heat is lost to the water jacket and exhaust and less gets converted to mumbo. More rigorously, low *expansion* ratio on the power stroke is the culprit. Check out a diesel with it's 20:1 or more expansion - they have rather lower exhaust temps than a petrol engine. Just as the big push compressing the air makes it hot, so the big expansion lets the burnt gases cool again, the more the better.

being a desiel mech for a long time turbo's are my bread n butter and have played with a turbo setup on my hemi using the draw-though method and once making a efi setup using a late model ford intake n rail matched to a tripple webber mani the hp went up 150 hp topping 340rwhp on 5psi.
theres no simple way of bolting on a turbo due to if u just use a decomp plat u are going to need longer pushrods and from there its an avalaunch lol. theres no reason looking at a project without sitting down with all the facts doing it once doing it right

[Sammy]

i fail to see how using a de-comp plate is any different to shaving the top of the pistons or whatever ? yeah sure you may bloke out the gasket or whatever but other than that i can't see the difference ... ????
