HQ Holden 253 Holley Sniper EFI Conversion - Part 1 

Yep Holley drop base - I have a Terminator EFI on my 65 Nova (from the Skid Factory so assume you've seen it) ;) and the stock lid fits in the stock location/height no probs. PART# 120-511

Hey mate, it’s made by Narva and got it at Burson auto parts

@@HackshopGarage Thanks I'll check them out

Yes mate, tomorrow’s episode provides and update

Thanks mate, sounds like an awesome car mate

Thanks mate!

Yeahhh we might have to start doing that test from now on haha

Hey mate, link below www.vpw.com.au/parts/hl550-511

Interesting, I hadn’t come across that, so you know what causes the issues with the duel plane?

@@HackshopGarage Not really sure. I now engine masters did a video on it a while ago and just couldn't get it to run right. Once they switched to the single plane, it ran perfectly. Have read quite a few things on forums and videos of similar problems. Seems to be the way the fuel is distributed through the dual versus the single. But if you don't have issues then all good. Maybe more of an issue on higher horsepower motors.

Yeah hopefully we won’t have those issues being that it’s such a low powered motor

Hey mate, we have heard that since installing it already, so we are going to try it and see how it goes. And if need be do as you say

Haha great to hear! They’re pretty warm ey!

Hey mate, We are working on having some Tees for preorder within the month

Hey mate, I went with the 4 barrel version, I’m not sure what cfm it works out to though

@@HackshopGarage no worries. How is it going a few months on? I have just had a 253 rebuilt, blueprinted/balanced and modded for strong street/drivable power. I was thinking about a Edlebrock AVS2 500cfm, but i must admit, this Sniper is very interesting

I havnt driven it a whole lot, but so far it’s going really well. I’m impressed by it so far

Nice tip! Thanks mate, will give it a go

Same as checking Piston to Valve clearance 👌🏻

I have

Scotland? Long distance viewer? Haha

@@HackshopGarage love watching all the cool cars you guys have. Unfortunately you just don't get that here or if you do it's a house remortgage to afford it. 😂 Keep up the great work guys.

Haha fair enough, thanks mate. Thank you for watching

Thanks mate, much appreciated, how far have you gotten with the install?

@@HackshopGarage I’m awaiting the diff to return atm I have taken out the welded diff it came with tossed that when and brought a MACE TOUQE LSD CENTER and brought all new diff rebuild bearings and new shims started to rebuild it all and found that the pinion lash had actully moved forward ten thou so marching off to the specialist to get it machined so it would fit but then the crush barring had to be realigned and all that crazy dialing in for the back lash was just all to much so I out sourced the rebuild lol......so in the mean while I rebuild all the back suspension to Au heavy top and bottom trailing bars and sway bar and Whitt’s link with all new nurothanine rubbers which wasn’t easy as all the old ones where crazy stuck but all done ready for the new diff to arrive .......then out of the big bad blue came a new full time job last week and so I have been move ing to Launceston which is great as I am only now twenty minutes from Simmons plaines our race track yay instead of like two hours but I’m now haveing to move very thing over the next few weeks so I’m a bit behind I have the loom and computer actully installed but I’m now trying to work out how every thing actully goes together to the old loom I’m using the premium wiring loom from haltech also wide band and flex fuel I have got the race works pump installed and new high out put injectors fuel regulator is in new turbo is hear but it’s massive so will need a lot of fab work before that goes on also the power tune digital dash has to be put in and that will be a huge task as well it’s all on the bench ready to go in but I’m now building kitchens five days a week now so I guess it will be night time activity’s from hear on in

Sounds awesome mate, sounds like you’ve been hard at it, good work, it’ll get there eventually and will be great when it’s done

Thanks mate, that’s awesome to hear!

@@HackshopGarage Cheers Guys.

Yeah with a tow bar that wouldn’t be so bad. We have heard it’s a good alternative, hence why we were going to use it. But we have found an option now

@@HackshopGarage as long as what ever you come up with works and you're happy with it, that's all that matters Just a side note, is it a genuine gts4 or a replica?

That’s it mate, and It’s a replica, an original 253 manual kingswood

@@HackshopGarage yeah cool, i have a replica which is highly modified and a genuine one i am currently restoring as a factory example Once i sort my pc crashing while editing I'll post more videos to RU-vid, the plan is one a week

Sounds awesome mate, a nice pair

Do you want one? Haha

@@HackshopGarage would love one

Atm my statesmans with out a tank

Vr fits vs too ,not 100% but pretty sure vn vp tanks are the same, judging by the video that vs tank looks identical to my vn one 👍

Basically just an EFI fuel pump set up really

Yeah they look awesome! But a little out of the budget unfortunately haha

No I havnt, have to check them out

Interesting, might have to look into it. Thanks mate

Is a TB, butterflies open at same time at same angles.(I have a Fitech 2x4 system on my HQ).

That is a good question, I wouldn’t know for sure. I guess it would depend on if the stock pump casing would handle the increased pressure EFI requires

@@HackshopGarage good point. Hadn't considered the pressure increase.

Haha I’d agree with you on the 253, and nah no dyno mat, the original build of this cars was years ago when I was a teenager, only insulation we used was left over house carpet insulation haha

@@HackshopGarage yea ive been know too use the sponge type hhaa

Thanks mate, much appreciated and glad you enjoyed it

@@HackshopGarage Definitely enjoyed watching. Always good watching 2 mates together doing what they enjoy. 👍👍👍

Haha we might do that one day

Haha glad you have found it. Lettuce alone SS would have been great!

Haha thanks mate, glad to hear it!

Haha thanks mate

Thanks mate, great to hear

At least with no Microphone on Nath got away with not being caught dropping shit!

Haha this is true

Other than drilling and tapping a second port into the manifold water way, an easy way might be to move the gauge sensor to read off and inline radiator hose sensor adaptor

crunch up some alli foil into a ball, works brilliant. also great for wrapping around wiring, hoses etc when painting, cleaning under the bonnet.

yeah what he said

Well I can tell u both fuel consumption will take some manual tuning to get better. I average 15mpg on highway with rowdy 440 cubic inch small block chevy with no overdrive. Th400 trans 3.42 rear gear and 28in tire

@@cfmechanic Yeah man, everything works together.

Haha thanks mate

Hey mate, the instructions came in the box. But if you go to the link below and scroll down, it has online installation instructions where it’ll explain the drilling process www.edelbrock.com/perfomer-holden-intake-manifold-253-308-2194.html

Legends!

CAE performance in Castlemaine is the company who we ended up using to modify the tank

Yeah that’s fair enough, it will be interesting to see how it goes

Potentially yeah, depends on cost and such, but it would be interesting to see the difference.
