Best way to get power from vg30?????

Post by **xxskouxx** » Sat May 23, 2009 3:30 am

i have a vg30 with only 68000 miles and i was wondering if anyone knew a way i get some more power out of it?

swap it for a VG30ET, it's the best bang for the buck aside fomr nitrous, if you're bent on keeping it n/a, the intake exhaust ecu are the common upgrades, if you add a lightweight flywheel, crnak pulley, cam geats I've heard of the n/a's getting 160whp, keep in mind they were only rated 160 hp at the crank, or you coudl send your engine to sunbelt or robello and spend $5-10k and get as much as 300 whp, or buy a wrecked turbo Z31 for $500, turn up the boost add an itnercooler and get north of 300 whp

yeah but how hard of a swap would it be?

But with as low miles as he has, why not just boost the one he has?

It's not like its THAT tough.

If I were you I'd go yard searching for the stock bits off of a turbo'd Z. Your gonna need some type of ECU re-flash to make it run right of course.

But like Evildky said, you could throw on an intercooler and crank the boost and your set!!

Just take the turbo manifold ecu and the top half of the motor and i would be set?

im not lookin to go crazy i just want something. i saw a miata with a eclipse stock turbo on it and do you think i can do that on my stock vg30. his was stock except that and cold air. can the block and enternals take it?

http://www.z31.comhttp://www.z31perform ... vg30et.com

go there and read up. there is a TON of information out there about this topic.

Yes you can turbocharge the NA block with parts from a turbo car. it's easier to just find a turbo motor to swap in.both turbo and non turbo blocks will hold a lot of power. more than the stock turbo will get you to. if you're a rookie mechanic, you better phone a friend before starting any of this, and if you're new to turbocharging, you need to read up on that as well. maximum boost by corky bell is an excellent start.

if i were you i'd start looking around for a wrecked turbo Z and just swap motors from that, it's way easier than trying to source all the parts you need for the swap. trust me.

Alright ill have to look at those and look around for an engine. thanks

I just read something CRAZY yesterday! A guy in the Trucks forum has replaced the TBI unit on his z24i (which has basically the same setup as the vg30i) with a carb, and the stock ignition works fine with it. He said it had a nice performance increase. Here I have been thinking you need a different distributor when it was always right there. The ECU dosen't even know the difference, just keeps right on firing away. You could mill the top of the intake mani on your vg30i, fit an adapter plate, and run a Holley350/500 2 barrel, or a Demon 2 barrel, and that would be a hell of a start.

except the ecu would run in "safe mode" if its not getting a MAF signal and limit you to 3k rpm, run like a** and not be useable at all. throwing a carb on a vg30 is not a way to make more power.

zer...rsion here you go

i stand corrected. but is the carb making any more power than the TBI setup?

I guess the question needs to be asked to the O.P., how much power are you looking for and how much are you willing to spend?

Website · Post by **Bronze MFP** » Thu Jul 09, 2009 4:45 am

People are almost automatically down a carb idea over fuel injection, so get used to that. If you want to make serious power on a VG, it is not going to be with a carb setup. Especially if boost is involved. The fact the carb works on the TBI setup so easily is neat, but other than that what else can you do with it?

Post by **seang** » Thu Jul 09, 2009 6:34 am

I'm not sure of the exact numbers, heres a vid of one running. http://www.youtube.com/watch?v=dGLtSPwdu8g This particular one has a custom Pertronix setup instead of the stock dizzy, and a Demon 500 2bbl on a TBI manifold.

Post by **seang** » Thu Jul 09, 2009 6:38 am

If one was gonna stick with turbocharging, then the carb idea is a no-go, unless one really wants to be "unique". I for one am a fan of lightweight everything, and I don't like the additional weight of turbo components. Hell, I don't even like dashboards, full size batteries, interior panels, radios, speakers, etc...

Id be satisfied with like 50 horses. im just trying to get to go a little better. im trying to see if anyone else has an idea about what gears i could put in it and run them to go better too. would i have to go to a machine shop to do a carb? how much power does it make

Website · Post by **Bronze MFP** » Fri Jul 10, 2009 3:41 am

quickest, simplest way to get 50 horses: 50shot wet nitrous system.

Post by **xxskouxx** » Fri Jul 10, 2009 6:25 am

yeah but i want a constant 50 horses. not when im full throttle or when i prees a button. Plus it will eventually run and ill have fill it up.

yer gonna need a bigger boat!

Post by **xxskouxx** » Fri Jul 10, 2009 12:03 pm

Plus won't the nitrous ruin the enternals?

how hard would it be to put it on

I've not installed nitrous myself but due to the inherent danger of it, I would recommend having a shop install it. If you have any leaks or wiring issues (like in the case of a bottle heater) that could prove to be very dangerous.

Post by **N2mesnob** » Thu Aug 06, 2009 11:40 am

Well hello everyone not really trying to hijack this thread but I think my question is similar and after reading everyone’s replies my question is still the same... I have a VG30E 150hp 180tq (new from the factory) with 200,000+ miles on it and I'm not looking to do a swap.If I get to the point I start thinking bout a swap I'm looking at getting a new rig.My question is can I put VG33 heads on my VG30E, and if so what are the pros & cons of this and what all is involved in doing so?On a side note if at all possible I would luv to keep the TQ higher than the HP.A friend told me the only way possible would be to increase my displacement by boring (port & polishing) & sleeving the block.I really not interested in turbo at this point as it will do the opposite of what I would like to see.Having said that... it does not really bare any relevance on my question.

Post by **mtcookson** » Thu Aug 06, 2009 12:12 pm

You could put the VG33 head on the VG30 but it won't really help you out very much. The cams are different if I remember correctly, which might give you some more low end power but I don't recall off hand.

As far as the torque deal, there are multiple factors that would give you more torque than horsepower. Generally engines that give more torque than horsepower have a decently long stroke as well as a relatively low rev limit.

Cams are also a huge factor for where the power band is. Generally you can get cams designed to provide a lot of low end torque and little power on the top end and vice versa (or anywhere in between).

If you wanted to do a good low end torque setup for a truck, the VG33 would be the best route to go with some cams designed for the power range you want. You can bore out the VG30 a little bit, but nothing like the VG33 can be bored out to. You could probably sleeve the VG30 to get a bigger bore but it probably wouldn't be near as cost effective as going the VG33 route to be honest.

nitrous isnt dangerous by itself all it does is give you a cooler dencer intake charge which makes more power its not explosive.

Post by **mtcookson** » Tue Aug 25, 2009 3:00 pm

I didn't say it was dangerous by itself, I said it was dangerous if installed improperly (or if something happened to the system). There are plenty of cases of major damage from nitrous systems failing in some way or not being installed properly.

Post by **67 411** » Tue Aug 25, 2009 6:39 pm

no your right i wasnt trying to be rude its just people see it explode in a movie and think its like a bomb. lol

Post by **mtcookson** » Tue Aug 25, 2009 7:13 pm

Yeah, I know what you mean.

Its been a while but I recall seeing some pictures of a car that, most thought, had a bottle heater and safety valve issue basically causing the pressure in the bottle to rise too much and rupture. That was some pretty insane damage. I think it took out a garage door as well.
