why would you want to? you would have to replace everything in the kit to support what that turbo pushs including a new engine. you obviously havnt searched for the kit since its been covered several times how its worthless to try and upgrade that kit

 

Great reading. Thanks for the write up!

 

I'm looking at a good deal on APS ST right now. If I did pull the trigger can I just simply do forged con rod + pistons and not worry about the motor anymore? (as far as internal build is concerned) Reason I ask is I'm seeing a lot of people doing stuff like valve sleeves, ARP studs, bearings, etc etc etc. I would like to keep the cost of this build to a minimum.

I plan on keeping it only @ 390-400whp.

Thanks!

obviously did not read at all because if you did you would be able to answer your own questions but since it's new years ill be nice and spoon feed you since it will likely never happen anyway. your power levels dont mess with it just run stock block, you will have to worry unless you have one of only a couple shops build the engine personally dynosty is the only one i would trust. valves are not needed unless your aiming for north of 1k hp heck i was making 600 on stock cams even and still going up before clutch gave out. sleeves are a bad idea for a street motor and unneeded below 700 hp mayby even higher no one has really pushed em. supposedly one person have oblong cylinders after running high power awhile but iirc that was around 900 to the wheels. again stay stock block and you dont need the other crap however if your going to build it then just build it right girdle, rods, pistons, stopper head gasket(dynosty has there own thats great and cheaper then hks) l19 head studs, arp lower studs, cosworth oil control baffle.


however once again 390-400 whp dosnt need a upgraded engine stock block will handle it, rods dont tend to bend till 450 whp

 

^Thanks for taking time to answer my question dude.

I should have mentioned that I track the car moderately and go to AutoX events. I am aware that the stock block can handle upto 400whp but I'm just a bit unsure if the stock block can hold up if the car is put under racing conditions.

But again I appreciate your feedback. I might probably just keep it stock! Happy New Year

 

Have read some of the forum here and have some questions about single turbo maybe not answered. I am planning a build at 320-350hp on stock internals with a single turbo. I don't need anymore than that for now. Would like to use a different turbo than the typical GT3582R and was looking at a smaller turbo such as a GT30 or even a GT2871R. Which should I use in order to put down the 350hp or less? Any suggestions? Please and thanks.

 

yah, get a weaker wastegate spring so it makes less power pretty simple no idea why you would want such tiny turbos not even sure a 2871 would be able to flow enough for our engines

 

not sure why it wouldnt if you did proper maintenance your probably going to have more issues with a built engine then a stock one at the same power level. especially since you mentioned you where on a budget, which shouldnt be mentioned with this platform there is nothing budget about it, so your likely to skimp and go to a cheaper builder and end up with a blown engine.

 

^Very good point. You da man. Thanks again!

 

I just purchased an 06 Z with a greddy twin turbo setup. Runs great and everything but I'm looking for a good shop in the west palm beach florida for a good tune. If someone could help me out it'd be great. Thanks

 

My advice dont take your Z to HP logic.

 

I heard they were good at hp logic. What's your experience with them?

 

couple of members here didnt have good results with jack, the most recent one was a guy with a G35 with the BP turbo kit, his car dynoed about 330ish @ 8-9 psi and jack told him those numbers were fine, he went to z1motorsports retuned his car there and the car made about 465.

 

Thanks for the input. Is there a shop in the west palm beach florida area you or anyone can recommend?

 

I took my car to forged performance to get it tuned.

 

I know this is talked about everywhere and I've spent hours researching this but keep getting different answers and nothing specific.. Okay I am getting ready to install my vortech v3 kit.. I have blower, bracket,innercooler,piping,and all hardware etc. I also went ahead and picked up some rc 440s and a walbro 255. Will I need a fuel return system using stock supercharger pulley?? I've gotten so many deferent answers when reading about this.. Some say yes, others no. Also I assume I will need a fuel pressure regulator. I have a aeromotive fpr just laying around but doesn't have any lines or anything and was wondering if I need to use this whats my best route to putting it in.. Last but not least.. With me only shooting for 400-420hp at crank will I need an aftermarket maf? This is another thing I've gotten mixed opinions on. Z1 Motorsports will be tuning my car using Osiris uprev.. Please don't bash me bc I know there are answers out there for all of this. I just want someone to strait up tell me yes or no.. So someone using this same setup please chime in. Your help will be greatly appreciated

 

You do not need FPR or return setup, you'll be fine with the injectors and walbro. I would personally go for slightly bigger injectors, but those will work. You can make up to around 400 at the wheels on the stock MAF so you shouldn't need one, but won't know for sure until they start tuning.. if you want to be on the safe side you could pick one up.

 

Thank you much.. Also right now I have a z1 6 puck clutch and z1 lightweight steel flywheel.. Anyway my buddy has a spare aasco aluminum flywheel just laying around cause he ended up going w a heavier flywheel. With me about to be installing my supercharger which flywheel would be better for my setup? And if the aluminum is my best bet would my 6 puck be good or would you recommend a different clutch?

 

You'll want a twin disc clutch.

I don't have a spare $1000+ for a twin disk.. Z1 claims my 6puck w be fine for the hp I'm seeking. My question was ab the flywheel.. Do I wanna use the z1 steel flywheel or the aluminum flywheel?
