Hello, I have just bought my first turbo car and know wnothing about it. I went from a ls1 car to a nissan vg30. I am just wondering what can I do to get more hp out of it. I beleive it is all stock right now running about 7 lbs. of boost. I have heard these engines are very capible of making good power. It is in a sand limo cruiser with a 2d tranny. Thanks for any help.

i did a vq project myself . it is a similar motor . the best place to go to is jim wolf technology . they know the nissan stuff better than anybody . they helped me setup my car . if you can find one an mdm100 , made by techtom, i believe . it is a great tool to have , it hooks up to the ecm by one or two wires and will give you a visual display of all the parameters the computer reads . you cannot adjust anything but you see whats going on . like temp, injector pulse width , o2 sensor and on and on . here is a link to the website , tim

lnk to a webpage that talks about the mdm100, i should have said that you can use it as apart of your dash it looks good and will display two parameters at a time any two you choose . tim

I also went with Jim Wolfe Tech...go to his web site and it will show you what you will need for the 450 hp package....I did it...but I did it a different way to save a little money....I bought injectors from Bill at Accurate injectors...I sent him my fuel rail and he put them in for me...I then got a mass air flow sensor and a bigger turbo...ran stock computer that Jim remapped and then took the car to there dyno-pac machine for final tuning....it put 320hp to the wheels...I have then since added bigger heads for about another 20-30 hp...the motr is extremely fast and torquey...I also added an intercooler...very reliable motr...I am running 16 psi of boost and these can handle 20psi no problem....definately run race gas for anything over 10-12...anymore questions let me know.

Thanks for the info guys. I really new to the turbo game. I wish it was like my duramax and just plug in a programmer. Can you up the boost wihtout adding anny thing?

Right now without doing anything you could turn up the boost to about 10 psi to be safe....you can get a lot of power out of these motors...very reliable...if you blow it up you can go buy one for about 500 bucks...cant beat that.

How do I go about turnig up the boost? What can I run it at stock if I put an intercooler on it?

when i ran my motor (vq i turboed myself) jim sold me different injectors and programmed the ecu for them , then he gave me the mass air flow voltage i could get to before my injectors could no longer keep up . in my case it was 13.11 volts which equated to 13psi . i used the mdm100 to view it in real time as i turned up the dial a boost . keep in mind that motor was stock compression and did not come turbo from the factory . so i bet the 10psi number is probably very safe . i would ask jim wolf to find out for sure . and like it was said the wrecking yard motors are so inexpensive , i turned mine up to 21 psi for 6 passes down the drags to see what it was like, the reason i only ran 6 passes because it took out a piston but lkq auto wrecking in chandler 400.00 bucks later a whole new motor . try that with a v8 . that part i sure do miss, its not even worth fixing if by chance you did have a major failure . i went through two motors in 4 years one i mentioned , the other i hade my oil cooler lines worm clamped and one let go while ripping pretty hard , they dont like running with no oil . i got lines made with crimmped ends and a better no oil light . kind a hard to see those small ones in the sun light .super reliable motor as long as you do right. tim

It all depends on how yours is set up...does it have all the stock headers and stock turbo...if it does you need to buy a manual boost controller to be able to or need to buy a turbo and a different set up to run a wastegate since the stock wastegate is built into the stock turbo...my set up I had custom headers built with a larger turbo and intercooler with a blow off valve between the turbo and intercooler and ran a wastegate before the turbo so I could turn up the boost...all set up by Jim Wolfe...where are you located...it all depends on what kind of budget and what you want to do...or you could twin turbo it...he might have the exhaust set up for that and it would fit in a buggy nicely....just need to buy two turbos and two wastegates...stuff you could probably find off of ebay.

Well I have what looks like a vacume diaphraam with a bar coming off it to the exhuast witch I am assuming is the wast gate. Do I do any thing with that or do I leave it alone?

If you could post some pics of what you have that would be great so I could see what you got...I forget what all the stock stuff looks like...you will be happy with the extra power that these motors are capable of...go to the jim wolfe website and to tech support and look at the 450 hp maf package...it will give a list of all the stuff you need and the prices...but dont go off those prices because there are definately better deals out there...

What's it look like?? I wonder if it looks something like this? LOL

Sure jumps good!

John did you end up with the flag? No biggie if you did. I just hope it wasn't left in the parking lot.

Here are some pics

You put it in your trailer, remember we talked about the blue light on the tip as you put it away?

That is what I thought but it is nowhere to be found. Very strange.

Are you sure you didn't put it in the back seat of the truck? I gave it to you at the door of your, scratch that, my trailer you made me sell you.......... Anyway, I remember you carrying something up to the truck and putting it in the back seat area also. Hope you find it! I think you need to buy a manual dail-a-boost for it if you want more boost. I thought it was the spring type, but now that I look at the pics again I'm pretty sure thats what you need.

Oh, by the way, I'm issuing you a formal "Cease And Assist Order" on your Avatar photo. You no longer have rights to display pics of "Tiki" without the express written permission of JohnBishopEnterprisesLTD,LLC,INC,SOB,ETC!

manual dial a boost should work on that setup . now the trick is not to much , it is pretty hard to not just turn that knob when yhou are getting more hp just from a turn . i learned the hard way . tim

OK Here is a more basic ? How much oil does thids thing hold and what weight/brand is recomended?

Are you happy now?

That looks like a newer vg30 maybe 90's.....mine is a 89 and it is different than yours...that looks really nice the way it is set up...definately a manual boost controller would be able to turn it up for sure...or Monday morning call Jim Wolfe and tell them...it should be Ben that answers the phone...very knowledgable....and tell him its in a buggy....he can tell you exactly what you need. Also..do you have a boost gauge in the car currently to show exactly the boost psi.

I will give him a call tomorrow. Thanks.

I went ahead and put 4.5 qts. castrol gtx 10-40 & k&n oil filter .

The waste gate you have is adjustable. IIRC, making the rod shorter will increase boost. You may need to remove the clip and slide it off the "lever" end. Loosen nut first then slide off gate arm, screw in a turn or so, and reinstall. To get desired boost it will take a bit of trial and error. The rod may be under some tension and take a bit to slide it off, it'll be a bit more difficult to reinstall too. You may get lucky and be able to just loosen the nut and turn the rod w/ vise-grips, causiously. Good luck!

Just curious:

Why did you go from LS1 to a V6?

That's better, I could still see "Tiki" in your avatar all last night, must have taken some time for it to change. What that "Kraut and Rice" guy said will work, just don't go crazy making it shorter. Turn it a couple of times and run it down the street, watch the boost and see how much it changes.

Thanks for confirming that for me. I was pretty sure I could do that but didn't want to touch it yet.

There is only one good reason to make that move. $$$$$$$$$$$$$$$$$$$$$. Needed to take care of some bills.

and to go faster

OK I played with it tonight and just gave it one turn. Have not had a chance to run it yet to see what it did. Can I run the dial a boost with this set up to be able to adjust it. Also does it adjust both ways or just up?

IIRC, the dial a boost just runs in line to the waste gate and changes the point that a pressure signal is feed to the w/g. The w/g is adjustable both wasy as long as there is room for it on the rod threads.

What sort of oil pressure should it be running? It seems to be real high. I thought the sended was bad so I bought a new one and it still reads between 70 and 100.

Is that hot? If not what does it read when warmed up?

That is when I first fire it up. I will try and warm it tomorrow but as I recall as soonas we got on the gas the one time we had it out it was pegging at 100psi.

Maybe try a 5-30 oil if being warmed up doesn't bring it down.

OK. The oil pressure looks good now. Next I want to intercool it. Do I need to have the computer tweaked after I crank the boost up some more?

Here are some pics [attachmentid=158241]

So can anyone tell me exactly what version ofVG30 this is? I have not seen anything that looks like it in all my browsings.

Your picture did not come through Mike. I was told that is a VG30T. Which means its the single turbo setup. They only used that setup in Japan. The VG30TT is the twin turbo setup that was in the 300zx twin turbo. Call one of the importers of Japanese motors, and they can probably answer more of your questions. I see them advertised all the time in the Auto Trader down here. I'll get the phone number for the local guy that specializes in those motors for you, his name is Jim something, and he's in the Scottsdale Airpark near my shop.

Thanks John. I have been looking around for aftermarket stuff and all the pics of these motors are much different looking than this one.

I like how they horked 442 and put their own twist on it.

Ya. One of my friends mentioned that the other day.

I think with bigger injectors and turbo you can get more out of it....does it have stock computer.

I have been told it has an aftermarket computer. John you can chime in since I can't remember the the name of it.

You could find out if the computer can be retuned....that motor could handle 16psi boost and with intercooler and injectors and turbo you should be close to 500hp to the crank....also call Ballisticmotors they have a lot of info on the Nissan with aftermarket computers.

Thanks for the info. How much should it cost to get a intercooler and Scoop? I looked at there site and on there engine package it was a 1700.00 upgrade. That seemed high to me.

The hardware shouldnt cost more than about $800 but the fab work might get spendy unless it's a top mount unit. If it is a top mount than you're paying for a bling scoop to funnel air into it, which again, is spendy.

I bought an intercooler of ebay for 150 delivered to my house...not a perfect fit but it works great...or Onanysunday has one for sale for about the same price that would work good...if you search for the other items you can always find them way cheaper...just takes a littel time...Bill at Accurate injectors will have something that will fit for a good price and look for a good deal on a turbo...the scoop shouldnt be that much either...its all in how much hp you want out of it.

I tried to pick his up but he just sold it. I want to get as much HP out of it with not spending too much money. What size turbo should I be looking for? Does a bigger turbo help it make more power? Also does it make it have more lag? Thanks, Mike
