VN Calais 5.0 Efi to Carb!?

[blownCalais]

Hey guy's,

just found out about your site, Awesome!

I am a bit stuck i am in the middle of my first VN build and i am about to rip the injection off to make way for the carby through the bonnet.

Has anyone on here done this conversion before?
I am not to shore about the wiring and so on.

The car is being built for summernats and cruises so for everyone that is going to say i am stupid for wanting to change it i understand but the whole filter through the bonnet really does it for me!

Let me know what you think anyway!
Cheers

Are you converting it to carby just so it can pop out the bonnet? Or are there other reasons too? If thats the only reason you want to do it for, why not get a high rise manifold for fuel injection? If seen them on 304s before... dunno who makes them or whatever though, have a look around on a few performance parts sites and you should be able to track one down.

BTW, welcome to the site mate! Any pics of the Calais?

Silly!, stick some throttle bodies ontop of a high rise if that's what you want, It'll still be illegal but it will be a whole lot less illegal than a carby

[VLDavo]

yea get a single plane manifold to suit the 304..... harrop do em for like 700 then like an extra bit of money to get em drilled out for efi....and with the carby it would never reach epa standards for rego

yeah my mate has a hirise on his 355, with a nice 4 barrel type throttle body! filter throgh the bonnet and all!

[blownCalais]

Really can you find out were he got it from, that sounds perfect.!

carby would be nice, like 750 double pumper or something, but i think you would have to get a pressure regulator or something, and just a 304 manifold to suit 4 barrel carb, not sure about the wiring, id just rip it all out and see if it runs, was thinking about doing this idea as well, but still waiting to get a 304

[blownCalais]

thanks guys will keep you posted.

[wes_v8]

u got any pics of this calais?

But why the hell would you?????? EFI kicks the c**p out of carbys.

[potshots007]

i know, efi more grunt, but i love the old school carbys, everyone is going to have there own opinion, i just like carbys, especially holleys

[253@7k]

So why spend the $2000-3000 on a 304 when you can get a 308???????

Agreed.. If you are gonna do all that work changing it to a carby, why not get hold of a 308 and trans that someone has already done the work on for you. That highrise and TB setup would look ok, but you would need a bug catcher to really finish it off

I feel the same way, i thought post would bring a few opinions to the table.

I have had a Vl 5.0 calais and i seem to like the vn motor alot more. Stock the Vn pulls alot harder ( i think )

Will take some photos now and post more through the build.

Once again thanks guys.

[greenfoam]

The VN motor does have alot more power, but half of the reason is the injection the other half the heads and manifold (down low)

[NORTI]

GA5DUP or something like that... from SC few issues back.... he did it, was nuts - however recent update in SC records it as being done over for EPA rules, & is now back as an EFI

yeah, if its a street car it would be very illegal to run a carby as there is less pollution or some crap, but if it were a drag car or something you could do it, like everyone has said if you really like the filter out the bonnet, just get a high rise manifold, 4 barrel throttle body and a big spacer and it would look alright

[blownCalais]

Hey guys long time no speaky,

Well thanks for all the feedback on what you all thought of going that way,
i have finished the build for now and we did the summernats without any probs at all, i actually was inumdated with questions about the paint and engine, interior and so forth,

So far we have stroked the powerplant to a 355 with flat top pistons and some minor flow work, we added some nos which gives the old girl a good kick up the ass being a 150hp shot!
We went with a holley 750 dp on a harrop high rise with the nitrous plate bringing it up another inch and a half,

I have painted the car and rather than go for that extreme look i have left it the same Green over silver however i darkened the green slightly and added a hint of glitter,

I had the interior retrimed in tan leather and fitted a beautiful set of BSA 20"s running 245 tyres! thats right with standard struts! try that one boys then come ask me how and i hope you have an hour for me to explain!!!!!
What a headache!!!

Any way let me know what you guys think of the finished product!!!! All opinions would be great tell me what you think!

[pow3rslave]

got any bigger/closeup pics?

[defa]

when my mate recovers from his heart transplant he is going carby on his 304. but that is only for a drag car.. his car has an engine fire so a lot was burned under the bonnet. so that is one reason he is going carby..
as for what someone said about getting a 308. why would ya when ya can get a carby manifold for $700.
as for the carby and injection arguement i reckon each to there own. i know i like the reliablity of injection. but carbies can be good if setup right..

[VLDavo]

i saw this on my way out of the nats its pretty phat... i got some close up pics of it i might chuck up later on

[blownCalais]

Hey could you email me some of the pics that would be awesome if you could as i dont have any apart from this one! thanks mate!

As for your mates car and the $700 to convert, let your mate know if he needs any tips to let me know and i will help him with any problems he may have, as for the $700 if he goes a dual plane manifold ie, a small one this may be possible (maybe) However there is alot of little things that have to be changed, ie, thermostat housing, temp sender, fuel pressure reg, fittings and so forth it all adds up, my car runs the harrop highrise manifold and these are going for around the 8>9 hundred mark, plus the carby and all the above mentioned it was quite costly in the end!

[nathans1987]

a carby will make the same power as a injected motor, the reason you dont want a 308 is because the block is weaker and the heads are nothing compared to a vn. i am thinking about carby myself because they make the same power and can be had for a lot less then injection because:
injector bosses dont need to be drilled
throttle bodies are not cheap as a carbie
custom tune will cost a heap as well
i would rather have injection tho because they run a heap better and better on fuel and last longer(all cars since injection last 300,000k easy befor that it was like 150,000) but a carby will have almost the same power(maybe 2-3% less)

you can get a high rise from tourke power or harrop.
