Hello, I am trying to find a way to run a carburetor on a VG.I understand fuel injection has it strengths I have a 510 with VG30E.This build will be used for racing.I have searched but can’t find if anybody has found a way without using the Saudi distributor.Has anybody used a optical trigger or the stock module, not sure what the 300zx’s hadWhat about crank fire?Anybody find a distributor swap or mix and match distributor parts?Thanks

Check this video out. Description says it uses Pertronix...http://www.youtube.com/watch?v=dGLtSPwdu8gIt sounds pretty good.

Here's a thread I think might be useful. It's cool how it actually works.zerothread?id=435279

Thanks for your reply SeangCool Video, I sent e-mails to Pertronix and Crane asking if they had any product that would work and both said no.Searching the web shows that some people claim to have used both.So these people have either done it or not, we have no way to tell. Not sure what the motivation would be to sit on the answer unless they are trying to make money on the solution by offering a product. It would be nice if they would share part numbers and what they did to make them work. I would be interested in purchasing the solution if it was in reason.In any case I will share my results success or failure; I am just trying to get the car on the track. If I like this set up enough I plan to put it on my street car.

I will use the stock ECU, Mega squirt or some the others I have looked at if I can’t figure out anything else.

Have you read the thread I posted? I know it's for a z24i, but it's relevant because it's still an EFI. Now, he just swapped a carb in place of the TBI unit, which has done away with the MAF sensor. People read this and say "it shouldn't even work". I have a hypothosis. The MAF might actually be sending out trouble codes, but the MAF circuit controls the fuel injectors while leaving the ignition to fire away as always. And since there is fuel and air being delivered by the carburettor, it doesn't matter what the MAF sensor senses.

PS, I have sent nkldime a message from my Youtube account, and maybe he will enlighten me on his Pertronix setup. I told him about Nico, so hopefully he will join and enlighten on a firsthand basis.

I did read the thread and was surprised by the fact it works.I would like to stay away from the stock ECU unless I have to run it.The goal for me is to make this a very simple swap.It would be great to hear from nkldime on what it took to make the Pertronix set up work.Thanks

Nkldime replied to my message. He said he got alot of hate about the carb swap on another Datto forum . Oh well, it's business as usual. Anyways, I'm gonna copy/paste what he said about the Pertronix...

hey man- yeah i have gotten on a few fourms and a lot of people are hating on the whole carb conversion. lol i am on the 510 realm but havent been on in a long time, because of a thread i started about my LSD build. I think i MIGHT have a account at nicoclub. ill check my " forgot password " and see what pops up.. what is the nissan/datsun section like? I just dont need peoples oppinions and negitive s***... I research s***, and do things the way i want and every thing has been working great. hah.. any wayyyys sorry man. ill check it out.. and my dritributer is custom made with a 6 cyl magnetic pick up for a z car. aka( 240- 260z) - running off a 6al? MSD box. piggy back module for advancing timing , rev limiter, ect.-

Nkldime is right on the money.I do the very same thing he does, research until I have enough information to move forward.Not sure why some folks have to flame somebody because they don't like the direction they have chosen to go.I also like the direction that Nkldime went with his distributor..I have been looking in the wrecking yards at the different V6 distributors from all makes that use magnetic pick up.Thanks for asking him Seang!

Hey guys... My name is Dale - 22yr old- nkldime on youtube ...



seang encouraged me to get my a** back on here, and i guess i do have a s/n on nico... lol- any ways- I appreciate every one being cool about my 510- Ive been on many fourms.. for my gto.. truck fourms for my truck.. and a few for my 510 and some are good for chat and questions.. but.. a lot are drama..so i just sit back and just read.. lol any ways - Hi!

Welcome Dale, I like what you have done with the VG setup.As you can see I am trying to do the same thing.I have a 73 510 that currently has the 200sx FI installed and a 510 race car that we are trying to set the motor back as far as possible to achieve 50/50 ratio. I want to convert both these Dimes to carbs.I have been researching as much as I can to make a good solid swap that will hold up to a 24 hour endurance racing.So far I see few ways to achieve this.Modify the distributor to accept a reluctor ring and such.Run a run megajolt box, Coil pack, EDIS Ignition module, VR sensor, 36-1 wheel.Here is something that keeps showing up.I talk to the Crane Rep and he said Crane XR-700(3000) ignition unit would not do what is being said.

“From another forum”There is a stock car series that runs the VG and they have used the VG30S dizzy until it was NLA. Their new way to get spark to the plugs using the stock dizzy is to use a Crane XR-700(3000) ignition unit. One of the guys who races in the series told me he sets the initial timing at 32deg and has no problems with lots of power.

Run a run megajolt box, Coil pack, EDIS Ignition module, VR sensor, 36-1 wheel. like a crank trigger? humm

Ya i read that thing to .. the engine ( vg30s) was in like a truck, over in new zeland. some one also said saidi arabia.**** ( sorry i cant spell for shhhit)

I tried and tried to get ahold of that distributer, because it will do every thing we need.. great! but.. my 2 contacts in New zeland had no luck getting through any where with nissan, and the only people that have ANY kind of communication with getting any or having them made again..is the vg30.com guys in Washington. any whoooo.. i got screwed by some fool on ebay that told me he had a vg30e dist with pick up.. i fell for it for 250.00 and the prick sent me a OEM distributer and fell off the face of the earth. soooo i got a magnetic pick up.. by protronics.. i can get the P/n if you want it. It running to a MSD box that i was told would work for what i wanted.. on the back of my MSD box.. there is a port for a piggy back. the module you can buy for the msd box.. will allow you to set redline, advance timing, ect. ect... another 250.00 if i remember right.. I have my VG set around 29* right now.. because i was running it on the street a lot.. if i bump it up in the 30's it will pull all the wayyyy. I only took it up to like 7200 then shifted but it did a dam fine job.. suprized me..scared me too.. engine sounded like a bat out of hell. With it set around 29* its really torquy from like 2k to 5-6 but it feels boggier up high.. Since i have been running it lock down i have had no problems.. but With my new build currently under way.. i am adding the spray.. and will need to retard timing when on the juice.. or. find my sweet spot for the track ( 32*ish) and retard it accordingly from there and lock her down, so when the n2o is acctivated it is mathced up. I love this engine carbed.. dont have to deal with having the ECU flashed..or injector duty cycle.. MAF's. o2 sesors, ect ect ect. I just turn my fuel up on the carb and let her suck as much air as she wants. do you have any pictures of your cars/swaps?

Not mine, but something I like to look at. I recommend it...zerothread/288475

ive seen this guy when he started it a while back... hes came a long ways.. so so sooo bad a**.. If only money wasnt a problem ..lol

For me to undertake a project of this caliber, I would have to be so well off financially that all that cool stuff would cost but a fraction of my disposable income.

Savings are more important..... there I said it! I'll stick with my fun little hoopties until I feel rich.

That is a real nice Dime datsun5ten posted "very clean".I like powder coating……..until it gets damaged, it’s very hard to repair.It’s also very hard to damage. Think about the size of the oven the car had to go into. If you can do all the body work, cage work and prep work it’s not that expensive.It’s having the tools, the knowledge, a place to work and the big deal for me is “time”. I learned by helping other people with their projects and horse trading my time and knowledge. I did fabrication work in trade for body work; I also made sure I was a helper with the body work so I could learn it.The more research EDIS ignition the more I like it. It totally removes the distributor and uses coil packs. I have worked with crank fire before and like how solid the timing is when running of a crank fire system. The EDIS can be set up for about half the cost of the MSD piggy back option.36-1 ring and VR sensor from a Ford Escort (wrecking yard)Coil pack from a V6 Chrysler (wrecking yard)EDIS-6 Module from a V6 Ford Explorer (wrecking yard)Mega spark to run it, more information if you’re interestedhttp://www.alternativeauto.com....htmlI am still reviewing finding a replacement or conversion for the stock dizzy.This my preferred methodThe cost is a factor as well since I need enough for 3 set ups.One for the race car, one for the spare motor and one for my street car..The race motor and spare motor need to be plug and play to reduce the down time in the pits. The goal would be to never have to touch the motor at all during a 24 hour race. I like the Chevy HEI module and have ran them before with great success.Greg

I'm carbing my VG.

Holley 2bbl, 500 cfm w/ a modded tbi manifold. (Can't find one of these anywhere. )

For the ignition I'm running a gutted distributor. It only has the rotor and cap left.

I'm gonna run an MSD BTM which is basicly a 6al with a timing dial, a blaster ss coil, and msd's universal crank trigger.

It's not too expensive but it's not cheap either.

I have run the MSD with a crank trigger before in a “non Datsun” and it worked fine.If I remember correctly the distributor is only used to phase the rotor in the distributor cap. / plug wires.EDIS eliminates all of that and the variation that goes with it.This is one of the things I like about it.

Are you having trouble finding the manifold, or the modified manifold?What part of the world are you in?

I can't find a stock tbi manifold. I'm in Florida in the US.

I have pulled the three that I need from the wrecking yard by my house.They may have one more “I think”.I will check the next time I go and if I have the time I will pull it.I have been buying them for $15.00, not sure what the shipping would be.My zip is 97009

before..

after modded

good luck

and mine installed. sit lowwww

Ok cool. Let me know what you find and if I can't find on in any of the junk yards down here we can work something out.

Dale you need to get a drive-by video. I wanna see that thing screaming by.

Sorry TJcars2 they were all gone.I have to go to another yard; they didn't have what I was looking for as well.Not sure about your part of the country but in the northwest we have a bunch of clunker cars that are showing up in the yards.Intake manifolds are un-affected by the process of seizing the motor.Do you have access to "pick and pulls" or we call them u-pull-it.I will keep looking for you, I still have things I need.

I'm not Dale, nor did he assign me to be his messenger but I'm bored so I'm posting the vid http://www.youtube.com/watch?v=foI5qvDKmao

Datsun5ten, have you or are you going to port the TBI manifold? How does it flow as the revs rise? Are you gonna continue to use it in the future?

Yea there's two you-pull-its near me. I'll take a look through them sometime soon. They're huge though. Need a few people to search them.

I over-looked that vid. Sweet. I hope mine sounds like that once i get my new exhaust and headers.

TJcars2 I have good news and bad news.“Good News” I found a TPI manifold at the u-pull-it today and I pulled it.“Bad news” this yard charged $24.99 for the manifold. $5.00 core charge and a $1.80 environmental feeTotal price was $31.79.If you’re still interested I will box it up and weigh it to determine what shipping will be.UPS, FED EX or US Mail any preference?

Good deal man ^^^^ and your freee labor... jk

Alright cool. If I can't find one down here I'll shoot you an email.

IM DALE. hahah ya i got the manifold from a local junk yard and had these guys do the mod. http://vg30.com/alt/contact_alt.html When i got it back , the runners were ported to flow nice into the head, but i am currently porting the heads..so i will need to port match the manifold as well-

Hey Dale.Since you have the heads out being worked on, "if possible". can you snap some pictures of the manifold?I would like to see down into the manifold to see how they worked the driver’s side center of the intake. It appears to taper from the outside to the center.It would also be cool to see what they did in the intake runners.My plan is to purchase spacers from Esslinger and weld them on.http://www.esslingeracing.com/...PCADPMy brother in law has a Bridgeport mill.It appears they mill the intake down to remove all of the ports that were located under the TPI. Were going to build three of these intakes.

ya of course man. my 510 is at my parents place and ill be going over there in a couple hours, so ill take some shots- and ya. they just milled the top of the manfold and i used Allen " plugs " to cap off the holes that were used for breathers... i think i had to cap 3 holes? - They ( vg30.com) offered to tap a port for a fogger nozzle but i ended up using a nitrous plate, and also to move the carburetor up so the linkage didnt hit the valve cover. there are a couple things to play around with- ill post pics later
