VK turbo

[hiy_po]

Just a few pics of my daily driver. Its not a show car just my toy. It started out as a 3.3 EST auto sedan and is now a twin carb turbo 5 speed. It is standard in aperance sept for a bonnet scoop. I really didnt want the scoop but the carbs dont fit under the bonnet. I still have original bonnet in the garage. I want to fit EFI in the future and am looking for a 3.55 or 3.36 LSD 10 bolt salsbury for it, and have a wolf3D ver4.4 that I want fitted asap, but with quotes around the $800 mark to fit it Im waiting to have the cash spare or looking for someone to do it a bit cheeper. Once the wolf is fitted Ill get a bit more closer to fitting EFI as well. Turbo is rated to 650hp twin carbs are Mike Vine Hi-flow jobs rated at 400hp it has about 350 rwhp ATM.

ah thats awesome man.. how much did the setup cost??

[VN_Luke]

totally cool mate!

bet you get a lot of confused looks when you WHSSSSSSSSSSSSSSSSSSSS past people

There's a bloke that's recently run a DELCO ecu (same as in VN/VP) with a holden straight 6.. could be a good way around the 800 dollar cost of a wolf

Delco VL goodness-ness

that might give you a bit more info on it.

the biggest hurdle would be the dizzy/crank sensor.. the rest should just be cut'n'shut wiring loom spec!

Cost heaps I really got no idea how much because Ive been putting it together over a couple of years. I took the original Rajay turbo into turbotech for some new seals and bearings couple years back and they gave it back to me in pieces in a box and said parts are no longer available for them I came across a new one that was meant to go in an airplane so stripped it of all its new bits and rebuilt mine. A Garrett Strata would have been cheaper and easier but I have a VK EFI intake manifold that has been modified to bolt onto this kit, has also got modified fuel rail and throttle body to suit as well. EFI would be too difficult with a strata; if I had to take a guess maybe $5000

efi with stratta isnt possible unless you mod up an EFI inlet manifold, even then you cant run blow through with a cooler, so not much point.

looks good man.
i had a stratta II kit on my built red 202. was good fun
best of luck with the rest of the build

It wasnt easy to fit the EFI to mine either but alot more possible than the stratta, Im not a big fan of strattas I have a mate that has one and it doesnt pull nearly as hard as mine, but it is carbed a bit different as he uses a 48mm DCOE webber. Im posting up some pics of my EFI dummied up onto an old head Ive got lying around



As you can see the manifold needed extending, the fuel rail is fully custom as is the throttle body. I have a new set of 600cc injectors from injection perfection to go in it as well. I bought a VK calais wreck that still had all the EFI gear I need for the conversion including tank and lines. so they are in the shed waiting. Fitting the Wolf3D is the next thing I need to do while its still on carbs. Trying to get more than 8psi of boost using the HEI is prooving to be tricky. Ive got a Vacume advance module off a datsun turbo fitted to my HEI dissy atm that retards the timing under boost but not enough to go over 8psi without detonation. It has a real fine line between pinging under boost due to too much advance and backfiring under boost due to too much retard. I have all the EST gear fitted, ie crank trigger, water temp sensor, manifold pressure sensor still hooked up, from what Ive read Ill need to fit a coil igniter to use the wolf and the HEI will get flicked in favour of an EST dissy. Im tempted to try fitting the wolf myself, I just want to cut off the original EST plug and solder on the wolf one to the original loom so it will all still look stock. I have NO previous experience with EFI computers so I am a little reluctant to try it, so if anyone with experience has advice Im all ears, my own advice is to save the $800 and take it to a shop

the wolf in the pic isnt the one Im using. I have a ver4.4 with hand controler.

[hiy_po]

Ive made a few changes to the VK thought I would post them up.
Took off the CD175's and added HIF44 1 3/4 SU's.
Added a adv/retard control to the HEI
Added a boost controler and gauge.
Coming soon is a pair of ram tubes for the carbs and an ICE ignition.
I am also looking for a 3.36 or 3.55 10 bolt LSD to suit VB-VK in good condition around Perth

Hey guys just a quik question with that turbo setup putting da carbs infront of the turbo neck i was planning on doing it on my vb..is it possible to put a intercooler setup on that ype os system coz some people say its not healthy dis dat....cheers ??

[hiy_po]

Is it possible to add an intercooler? Yes it is BUT it puts a mix of fuel and air through the cooler and thats not a good idea. Intercoolers ar made to cool air only and having an intercooler full of fuel is like a bomb waiting to go off if ever anything punctured the intercooler I wouldant want to be anywhere close by or in the car if it ignited. So in sumary is it possible yes, Is it practicle or advisable NO.
Meth injection after the turbo is the way to go with these setups. Get the cooling without adding lag.

awww ok i get ya and also is there any way u can install a turbo system on without connection the craby to the turbo necj or do u have to?? coz i think some guy had did tthat ona a vc commdoroe he didnt have the carby connected up to the turbo neck

[hiy_po]

I think you are asking about a blow thru system. Blow thru has turbo 1st then carb 2nd and carb is usually bolted to the manifold in its stock position. My system is a draw thru has Carb 1st turbo 2nd and manifold is just a joiner to join turbo to engine intakes. Blow thru does have advantages over my setup as you can run an intercooler between turbo and carby and as long as your carb is modified to suit blow thru (not all carbs need to be modified for blow thru but holley's do) the system can be easier to install and give impressive results. My particular setup is not very suitable for a blow thru setup as the turbo takes up the space were the carby would be sitting. But if you have a custom manifold (usually a low mount) it can be easlly done. Below is a pic of a blow thru setup I started but never finnished

ahhhh k thanx alot mate u answered ite wat i was looking for hehe looks goood btw
