VG30E turbo build

video of idle. Isky cams, 270 duration 465 of lift (doesnt really idle...)

Boost gauge install pics (building manifolds in a few weeks, just wanted to have the small details already done):

sounds like a mini dragster!

[fisch]

So sweet! Man I love a VG30 with a gnarly idle. What are you running for exhaust?

[cjr198car]

2 inch y pipe to a 2 1/2 single out back (I also have a 2 1/2 cut out that exits before the drivers side rear tire). The exhaust system is getting a complete overhaul in a few months.

Thats a damn good engine you got there!

[Farmer Joe]

wow! that sounds pretty damn mean. i gotta admit, i have a mushy spot for cammed up 6 cylinders. that sound just can be matched by anything else.

*Cough cough* Cammed up 8 cylinders perhaps? lol

[cjr198car]

Yeah I really like how it sounds! I was not expecting such a radical idle.

[Jesse C.]

I like that! Sounds nice!!

[beebeecivic]

Jesus! I wish I had a Vg30 to play with :/ what are your expected HP/ TQ.

[cjr198car]

300whp/330-345wtq with the parts below (not certain really, but thats my gut feel).

 

Precision Turbo 5857 with a billet wheel and V bands/Precision Turbo PW46 external wastegate

 

 

Diabolic Z Products header flanges

 

 

Cooling Mist 250psi alcohol/water injection kit

Man had to listen again. Like music! I have a VG30 I picked up for free under my work bench. You sure have me dreaming!

[bonvo]

may be a stupid question but why an exhaust temp gauge? doesnt seem like somthing that would need to be watched

[cjr198car]

An EGT gauge is just another monitoring device. It can be used in conjunction with many other monitors (like a wide band or narrow band gauge). Here is a tech page with regards to tuning with an EGT VS X, Y, Z:

Long story short you should use a wideband on an engine dyno or chassis dyno, make note of your EGT and use them as a reference to what your engine is doing under real world conditions.

Hey Colton, Where did you find the info on seting up your wiring for the EFI?

[cjr198car]

Im running a Tec3 for engine management (I scrapped all of the factory components less a few sensors). The setup is a complete custom deal so I dont know how much I can actually help you on this one! I can recommed z31performance.com for vg related tech/wiring.

turbo manifold construction pics!

im really interested to see how you run the piping from the other cyl bank to the turbo

[cjr198car]

here is the drivers side manifold (finished last night). The two manifolds will be connected with a crossover pipe in front of the engine (no pics of it yet).

 

 

Turbo placement/downpipe

 

 

Overall look (the fuel cell on the right is for water/meth injection)

[bonvo]

accross the front huh hmmmm no room to go along the back im guessing? im also guessing that is why the turbo is so far forward correct? how are you going to run an air filter on it?

[metalmonkey47]

[cjr198car]

Yep no room on the backside. The turbo is large in general and the placement is about as close as I can get to the valve cover/radiator/engine and as far away from the relays/fuses/electrical. The turbo placement is also good considering the down pipe will not have to fight with the steering box for space. I will be using a very short filter (I do have space between the headlight and turbo, the pics just dont show it off). I hope to have the car running tomorrow for the Minnesota Sport Compact spring opener.
