Ok guys. to start off, new to the forum. I own a '04 5AT sedan. havnt done a single mod to it cause honestly for the longest time i thought it wasn't worth it (dont hate im just one of those GM LS fan boys) im certainly not new to modding cars but want a little input on the G's. this all started because about a month ago the motor took a dump in the car at about 132K. blew a massive chunk of oil gasket out while driving. went extremely low on oil. spun a bearing or 2 or 3 and put valves into pistons. im picking up a 60k mile motor as a replacement but my desire to match my GTO's performance wont leave me alone. so i started doing some hunting and came across a good friend who is mid turbo upgrade on his '12 WRX hatch. i now have his factory turbo and it will be going in the G. ill be running a relatively small single turbo (right around a 50 trim) and looking to run about 8psi. but i need some mounting suggestions. does anyone know how difficult it is going to be to try to rout BOTH exhaust pipes up to where the factory air box sits like on most the single turbo kits. should i not mess with a top mount and just put it underneath the car. ive seen stuff about factory fuel system supporting 400whp, is this true? whats going to be a cheap yet effective method of fuel management to tune for the new boost. will the tranny and diff hold up to the added power for an extended period of time. im NOT looking for ***** to the wall power. i just want to safely and reliably put the car into the low 13's (or faster if i can do so safely on this turbo) and i also dont want to spend a ton of money (exactly why im making my own turbo kit rather than buying one) any help. any insight. or any major issues you forsee that i have over looked please give some advice my way. as soon as the new motor is here ill start posting up some pictures of the project along the way

 

I would search over at my350z.com in the FI section... More info over there and at 400 you will be maxing out the fuel system of the factory... You will need a larger in tank pump and injectors at the minimum... Check out over here for good info and make sure to do a bit of searching before asking too many questions to avoid getting flamed... http://my350z.com/forum/forced-induction-182/

 

If you're even half serious, OP... my350z is going to have more guys that can answer the extremely technical questions you will likely have in an endeavor like this. This isn't to say there aren't guys here who do all their own work... there are simply MORE of them over there as mentioned above.

 

post this on my350z.com they would love to help you

 

Alright will do, also i have decided against the factory WRX turbo. i will be using a GT3788VA

 

A single turbo setup shouldn't be too expensive or simple. What is your budget for the project?

My Ideal Turbo Kit:
DOC Downpipe and Crossover


Turbo w/ exhaust flange for custom exhaust
Intercooler
Custom Intercooler Piping Hot/Cold Side
Custom Intake
Engine Management: Cobb Pro Tune
Walbro 255lph fuel pump
VQ30DET 440CC Injectors
BOV are for sissies
Misc parts: hardware, lines, etc..

im hoping to stay under 3 grand all said and done. hoping to be at about 400 whp

 

3k? Wow... wish you'd said that in the first post.

 

For 3k, you can make it into the low 13s without the turbo. Gears, spacer, exhaust and call it quits.

 

ide really like to hit 12's wether it just be bolt ons or boost.

 

Well if 12s is all you wanted a 3" plenum spacer is all you need. If you got a titanium shift **** you might actually see high 11s but that might be overkill on your budget.

 

All those reliable parts plus Cobb for tuning? nice. I needed a good chuckle before I left the office

 

Unfortunately fuel will be an issue. Had 460ccs and it was close to 1:1. (460whp with 460cc injectors).
As for fitment, anything larger than a Gt28 series (sorry i don't know the size factor of precision, HKS, berg warner et al.) will require machining the motor mounts to fit the turbo next to the exhaust manifold. Standard single turbo set-ups from what I have seen in regards to our car is mounting the turbo where the vortech setup is. Again, I can only go by what i have seen with a supercharger installed. I have ran turbos only once I got my G.

 

I don't see why a COBB pro tune is a big issue. It's all about the tuner. COBB does the same thing osiris does plus you get the accessport. I'm tuned on cobb and it's great.
