Hey everyone. I have the VG30E, and was going to turbo it a while ago, but decided against it. just because they take so much work and cost so much. so other wise, i was going to have my intake manifold cromed, have my ports polished, put in new lifters, valves, and springs, along with some cams. while i had it out i was going to have my heads bored out and put some higher compression pistons in it. anyone sugjest a stroker kit? so the questions i have are,

Where could i find some nice cams for the VG30e? i havent looked much, but could only find um for like 700 a piece. anyone have any experience with um?

I heard i could lay down my intake gasket and etch it, and do the same on the other side, and then grind my ports flush to help flow? good idea or no?

Whats the most stock VG heads can be bored out to? and what kind of pistons should i get for it?

what would a stroker kit for a VG do? worth it?

Any advice on this kind of stuff would be great. im sellin my race bike, and i saved up a little, so i when i get the stuff gathered up i wana start.

 

its not that bad if you can get access to Z31 VG30ET parts like at a junkyard, thats a few hundred max, then get NisTune or JWT and a few custom parts. of course if you dont do everything yourself youre gonna get raped by labour costs

 

well yea id do it myself. i just cant see it happening. its way to much modificating. and if i raised the compression to 12:1, and turbod it later with like 6 pounds of boost, thatd be crazy, and it wouldnt be hard on the turbo. not saying thats gonna happen tho

 

well to stay NA just use VG33 parts IMO

 

yea. but im plannin on my list above. just need some advice.

 

anyone?

 

don't chrome...have the manifold and etc polished. i actually have a polished intake elbow FS if you're interested.

port matching is what you're you're referring to when you're cutting the ports to the same size as the gaskets. is it worth the money to power ratio? personally i'm not sure.

JWT made nice cams for the VG30E...not sure if they still make them. look into the stage 2 if you're manual and can tolerate slight lumpy-ness at idle.

piston and bore/porting choices depends on what you're looking to get.

IMO the "cheapest" thing to do is a small turbo. if you don't know wtf you're doing with porting you can ruin a good engine. same for port matching and boring out the block for larger pistons. the other alternative is to find a VG33 and use that.

 

Actually what your planning isn't too bad of idea but really if you already don't know the answers then don't do it yourself. Instead of taking your engine apart, why don't you swap in a Z31turbo motor or look for a good Maxima tuner/shop by you and see what they can do for you. I know your looking for the easiest thing to do to what you got already. Port N Polish is good way to go if your experienced, personally I've never port n polished anything but American Muscle Auto's. As already suggested, if your not experienced you can **** up a good engine. But if you can find someone to either help you that has the answers you can't answer or a good Maxima tuner. What have you done 2 your exhaust or intake?

 

Yea, i was just gonna take the heads in to be bored, but i want to go the biggest i can posibly go on the VG30, and then i just wanted to know what pistons would give me higher compression. and i wouldent port it, id just polish everything and match the ports myself. that shouldnt be to hard. and i have a cold air direct to a scoop, and 4 inch strait pipe all the way back. here was my plan... pull the upper intake off, and have it polished, same with the middle bracket and lower manifold, pull the heads, and have them bored, put in the bigger pistons, match the ports, polish the inside of the heads, seat the valves a little better, and put it back together...

 

and i want to hear lumpy ness at idle... but here is what im going to get for cams...
DESCRIPTION:
S2 VG30/33E BILLET CAMS .473"/266 DEG . THIS IS THE BIGGEST CAM THAT CAN PHYSICALLY FIT IN THE HEAD WITHOUT MODIFICATIONS

 

what about this ECU also???
ECU MAXIMA 89 MANUAL_TRANS./CAL VG30/1C Top speed limiter removed, rpm limiter raised, fuel map/timing curve optimized for premium fuel, special programs available for turbocharging and larger injectors and MAF sensors. Call for details.

 

if youre planning on JWT be warned you will have to send it to California to get reflashed always, hence why Nistune is better

 

to be honest this sounds like a pipe dream.
go get your parts...start working on it. let us know your progress and show us pics.

 

i need to know what size i can go boring tho. so i can get my pistons. and posibly get some tips for the build.

 

/thread

 

1 - take the engine out.
2 - take off heads
3 - bring to machine shop
4 - machine shop will advise you what pistons to get

don't give me the BS that you're going to bore the block yourself unless you're rocking a CNC machine at your house.

like i said...this thread is a pipe dream.

 

 

I just had 2 laugh at this shyt mann!!

 

My question is how much money do you have? NOT going to have...but is in saving or tucked away in that secret place?

You've got great feedback on build info. VG33 block and bottom end. VG30 top end/intake and heads. Schneider cams will do a cam grind for just a little over $200 a set. Not sure if any cams have a lope to them for a NA engine....I know the set I have from Schneider for my turbo has a little lope though....which is nice. Schneider also has performance valve springs. Ferrera (sp?) valves. Of course, all new freeze plugs, gaskets and water pump and oil pump (believe me!). Upgrade to the later VG "round tooth" timing belt. Upgrade injectors and get a nice engine management system. Poly motor and transmission mounts. VE (VLSD manual) tranny. Should be a very nice build.

Again....how much money you got? I'll say this alone will run around $1500...depending on how much you can do yourself.

 

I got about 2 grand. and i already got poly mounts. and i dont want my cams shaved, i want bigger ones. and to danny, no im not boring them myself. but i shouldnt need bigger injectors should i ? if i really do, ill just get some 300's injectors, i think thos are about 350cc. maximas are like 180 i think. and if i do that ill just get a better o2 sensor with i nice fuel management system and call it good for now. and what should i run for compression? id like the highest i could go on the vg.. but i will be getting better exhaust manifolds to go down to my 4 inch.

 

4 inch..?

 

ok then you will bring your motor to a machine shop...LET THEM advise you what pistons you can get. once you figure out the over sized pistons then you can decide what compression you want to get.

4" exhaust? why not go 5 inch or 6 inch exhaust? this is not a diesel motor you're building right? i doubt there's a need for anything more than 3"..but if you want 4" then by all means go for it.

better O2 sensor? show me what's a better O2 sensor. you mean a wide band?

compression is determined by what piston style you use. read up on what's ideal compression. i'm not going to sit here and do your homework.

yeah Z32TT injectors are 370CC.

again i'm just posting to "entertain" this because at the end of the day i KNOW YOU WILL NOT DO THIS AND ALL THIS IS A PIPE DREAM....but prove me wrong.

 

I put a 4 inch exhaust on it...

 

anything bigger than 2.5" on a NA car will produce less backpressure and give less performance right?

i cant see 4" on a NA at all

 

Seriously?

 

guessing lulz shall ensue...

 

To make it official:

 

okay, that solves my piston question.

and i already got a 4 inch exhaust on it. just because i didnt want it to sound like a 4 cylinder, and i had some pipe. so i welded up an exhaust.

yes i mean a wide band O2 sensor along with a nistune ECU, i just bought the lap top and car mount for the fuel managment, ECU, and O2 sensor.

and i know that, but itd just be nice if someones done this and knows what style to use.

so im going to get thos injectors, wait on pistons, posibly new rods, depends, JWT springs and cams, Apexi S-AFC II, MSD ignition, nistune ECU, wide band O2 sensor, and the rest ill do my self. basicly just polishing and matching ports and seating the valves. along with a full gasket kit and front main seal. posibly a walboro fuel pump and better oil pump. already got a new water pump.

im not dreaming about this. i was dreaming about a turbo, but i got the money for this build, the time, and a place to do it.

 

yea no backpressure is better then a lot of back pressure.... right?

 

In all seriousness, the 4" exhaust is completely unnecessary..

Even if you were pushing 400 whp you wouldn't need a 4" exhaust

 

Well yea i know i didnt need that. my car dont even need 2.5 i just like the way it sounds, and i had some 4 inch pipe.

 

i think you lose tq with too little backpressure

 

you gain hp with less, and gain tq with more. is what i thought. when i put my silencer in i can tell its got more bottom end. but its not bothering me. if someone would want to sell me an exhaust i might be interested. i found some race headers on classifieds on here tho. i might by um. so id need a exhaust to bolt up to it.

 

we have a mandrel bent 2.5"/3" catback group deal going for $190 shipped right now

 

hmm. Pics??

 

none yet, still figuring stuff out

 

What's this about a current group deal for $190?

 

This thread is a bit unbelievable but.. ill add to it.... for starters its not back pressure.. its velocity.... get it right. I love VGs but im first to admit NA they suck, i dont care what you do to it it will still be slow. Clearly you have not done any research about almost everything your talking about.. you don't Bore heads you bore the cylinders in a block. And why would you get a S-AFC if you were going to get nistune. Do you even know what a wideband o2 is and what makes it different from a narrow band? How are you going to "Seat the valves" yourself, the only way you could improve on the valve seal is to have a machine shop do a good multi angle valve job. When someone says "regrind cams" this IS making the cam bigger because they take material off the bottom of the lobe making the lift higher.. why would someone want worse cams. Stroker kit... who makes a stroker kit, news to me. And for pistons... there is No simple way to get a VG to make that kind of compression short of having custom pistons made. Serioulsy though.. what happened to doing research, does any one know how to self educate now days. . its very clear that you dont understand many of the concepts that your talking about. Do some reading about EVERYTHING you just said. Type it in google and just Read... read and then when your done with that .... READ some more. Im not trying to be a **** robster but this was a little over the top.

 

^^^^ZOMGROFLMFAO!!!!!
HOW MANY TIMES HAVE I SAID THAT TO THIS FOOL?

 

Once again....this is a pipe dream. You know what SHOW ME THAT 4 INCH EXHAUST YOU GOT WELDED UP UNDER YOUR CAR!!! I had a hard time with a 3 inch but you got a 4 in there I want to see pics.

Keep this bs up and this thread will be locked.

Nistune and afc????? lol
