202 turbo

[vh_commydore]

iam currently building a 83 vh, ground up bare shell build have got brand new 202 blue motor, mild crow cam, wen funds allow will buy forgies, xu-1 conrod bolts, nitraded crank, and have motor de-compressed, im thinkin of running a t3 high flow/t4 hybrid, on a custom manifold,.. how hard will it be 2 run a vk head with efi as i have been told it will be more reliable than carbs. im not lookin for huge power but a nice cruiser. will run stock diff with mini spool till it blows then buy vl turbo diff. vl brakes for the front, new suspension, maybe manualised box. wat mods need to be done to run efi. will source rails and so on from wreckers or buy new. car is finished ALOT of body work and is ready in primer now. will be stock red (i think pheonix red) with gold pearl. all trim and bars re-done. plus a few choice sle parts. thanks,,,, sorry bout the novel

if you use a vk efi manifold that will hold your setup back as they just dont flow so either go carby or get something custom made up

[vh_commydore]

if i went carby would it be like a blow through system,, or wat efi system would you recomoend

[Dose Pipe]

if you went carby you can still run a blow through setup with a boost preped holley

if i went efi the best thing to do would be to modify the standerd manifold eg: cut it down a bit and put a new plenum top on it with belmouths for each runner and also would run a new ecu like a wolf it only needs to be a fuel only ecu as theres nothing else it needs to do so prity cheap to set up

the best bet (and i keep saying this) the garrett strata kits they are really good bang for buck theres a torana in sydney i think running 10 seconds with strata manifolds they are a draw through carby setup normally running twin strombergs or a webber but you could use a 4 barrell holley like eze10's does

id recomend fitting a vn computer and loom and remove the distrubtor all together. then you have more control over spark fuel maps ect and you can get the memcals retuned to run to its optimum proformance/economy depending on your driving style

i have seen a turbo 202 (all stock internals) put out 459hp on unleaded at the fly wheel but it didnt last long........3 pistons melted

[Dose Pipe]

like above vn ecu can be used but the throatle body needs to be used afaik but your removing the afm so theres a bit of restriction gone, i might be making up some efi 202 turbo manifolds with a t3 flange soon if i can get a doner car to fiddle with

[Dan355]

You can fiddle with mine Id also recomend a boost referenced fuel regulator. Theres alot of mucking around with the memcals to get it just right especially with blown/turbo setups. Get a comp that you can tune on the fly this would save alot of time.

Do u have a 202 turbo setup 4 sale? Dan or have one installed? what did u pay 4 yours?

I'm waiting on a price for a turbo 202 setup from a friend of a friend already picking up a 202 blackhead for 50 bucks!

Also got a possibly ecotec engine on the way for my 2nd ride

[Dose Pipe]

nah he doesnt hes saying i can use his car to make the manifolds on

[Goon]

Oh well, i hope i get a good price if it can get my hands on it

[Dan355]

Theres a ad on one of the forums i think on HH for a completed 202 turbo setup with motor and box.... dirt cheap too!!!

what would u recomend to do to the fuel system to run with the standard computer as i dnt realy want to change it and iv seen it work before. im seting up my sc14 sc efi 202 mild haed cam stock bottem end and etc eny help would be grate

anyone feel free to correct me here, but from everything ive learnt about VK EFIs, from wanting to do what your doing now and from trying to fix the thing, you wouldnt be able to run a standard computer because you cant tune it. its an analogue computer, meaning you cant plug it in and change anything. some ppl have run standard computers, but they have changed bits on the actual circuit boards to get it to work. soooo much easier to just use an aftermarket setup that you can tune easily. theres a few guys on here that have done it all before.

cheers never know you could change the circuit bord, but im not tuching the computer, on the set up iv seen it remained untuched they changed the fuel system eg regulater and fuel return, it was on a turbo 202 in a vk also wich ran a 12sec 1/4.
does eny one know what parts are needed i was going to try diffrent regulators from diffrent turbo cars and see whats closest or get an adjusting raising rate adjusteble regulator and go that way. Eny one that knows how to set the fuel system up, if someone has done this previosly or has experience please help me out cheers

You need whats called a rrfpr (Rising Rate Fuel Pressure Regulator) basically al it does is as the vac becomes boost it will allow the fuel pressure to be increased. You will need to set this up as you don't want it dumping in too much but once it's adjusted you can leave it alone. You may or may not need to swap your fuel pump for something that flows more, if you do need to increase it then make sure your fuel lines can handle the extra psi. You will also need a fuel return line if your car does not already have one. And for god sakes, swap out your fuel filter also!

There a guy called Sammy that might read this who is running the VK efi setup with a VN-VR style ecu on his 202 and that's really the best way to do it (or an aftermarket ecu) , he is running his NA but it's practice for when he boosts one

Do you know if he used an RRFPR?
