new to the forum with some questions

[Winterjay]

hey how's it goin everyone, new to the forum and i've got some questions about the Z being i'll be going for a used 05 rather soon. i currently own an 06 Scion xB so you can see my want for a secondary with power. the mileage is great and all, but seriously no power and lituraly starts puss's out at about 90mph.

my goal with it is to make seem somewhat close to a sleeper. i say somewhat because it'll be turbo'd. i'd like to know how much boost from the APS single system can be reliably used over it's normal 8-9psi? i've heard of upo an effective/reliably used 12psi which resulted in 420whp/430lb torque without having to build any part of the motor is this true?

also, i would like to go single turbo as i'm told by many that going twin actualy hinders the handling because it becomes too much power too early. thoughts on that?

also, how reliable after turbo'ing the motor with the about 400whp *380-420whp & torque* has the Z been?

also, on a smaller note, i'd like to know what size and location of the audio components regarding the speakers. i do audio design and developement and have some plans for the Z's audio system. keeping the door speakers but i need to know if there are any dash pieces and how easy is the settup behind the seats capable of being removed? i will be using a single 18" made by Beyma *a German live audio company, the best of the best woofers for vented design subwoofer cabenits* the 18G50 being it's rather lightweight for an 18" *26lbs* and EXTREMELY efficient requiring hardly any power at all to have a rather loud reproduction and useable play range down to 35hz and designed specificly for the Z's natural low end gain. woofer is also just the right size to hide just under the hatch door under the metal part after the window making it perfect for a stealthy install. full range components will be JBL 560 or 660GTI *depending on door speaker size* high fidelity neo component system *total component system all togethere, speakers/tweeters/crossover and cables weigh less then 9lbs.*. alternator will be a modified OEM alternator to produce 130amp idle and 240amp max so that the full electrical system will be upto par with performance power demands and audio demands at the same time.

for first mods i'm going for CF hood, fenders, doors and hatch for a nice weight reduction. i'll be immediatly repainting the car and CF pieces to match so that i don't get noticed riding with CF doors *highly illegal due to safety reasons*. wheels will be custom ordered Ray's TE37's in matching color paint to the vehicle's color *regardless of body color wheels will be flat black with clear coat or enamel black if i decide the body to be enamel black.*. exhaust being Injen SES for that nice beefy sound and Turbo wise hoping to finaly get setteled on either the APS single or APS twin. i don't want to go s/c'd being i kinda like the fact hat turbo'd systems hardly touch your mileage while just cruising unlike a supercharger and only really effect mileage while going pedal to the metal which regardless if turbo'd or not, mileage goes down the drain doing that anyway.

answers and optinions greatly appreciated!try not to harp too much on the toaster with wheels, it's actualy not too bad of a ride, LOTS of room and great mileage but still a family car. only real downside to it is that it's noisie, theres lituraly no acoustic dampening so road/engine noise is rediculous.

again thanks!Jay

anything at all?

You seem like you have your mind set pretty hard on this Z. However, if you're trying to make it a sleeper, good luck to that. Most people know that those cars are pretty hooked up already. If you're trying to find a sleeper, I would spend the same amount of money on a 240sx and drop a butt load of money into it. RB25DET, bb turbo, 4c intercooler, etc. But if you want the Z then go right on ahead. I'm only saying it's not much of a sleeper

Wait until you drive this on the freeway, you will get respect from the other drivers. When you are used to be cutting off, you will notice that people think twice of cutting of a Z or they get a growling V6 in their ear!

try to get an 06, you get HIDs stock and better brakes

400 whp seems to be the limit on the stock motor, the rods and pistons can't live long at taht level, if you want more power then you'll have to plan on building a bottom end which adds greatly to the cst, as for spoolup vs handling, with a standalone managment system you can retard the timing in the intermediate range me I like a agressive spoolup, maybe your source wasn't a good enough driver to handle it, as for twins vs single, single is gonns be cheaper but it's hard to place a large single turbo, me, I kinda like the greedy (yeah I mispelled it on purpose it's a nice kit but dang makes my butt hurt) twin kit, it comes with emanage, injectors, intercooler everything you need to get to 400 whp, there is something to be said for a path thats already proven

haha h no trust me i know fully well of how much respect it has on the freeway. a buddy of mine has a Z and let me take it for a short spin about a week ago, the one thing i have a problem with in most sports vehicles is not being able to see the hood at all which make me want the Z even more being i have full view of everything.

i know it's not really going to be the stealthiest of a sleeper... first of all it's a Z, second it's got the turbo's BOV and third the exhaust *injen ses*. but for the general look for most i'm going for the stock clean look which on the freeway just cruising, it would be hard to tell if it's stock or not. but basicly the idea is when some smart one decides to think *oh it's just a Z* i can do this --->

i kind of figured i'd have to build the block a bit which i'm perfectly fine with. i eventualy wanted to just get a full cosworth set, the low compression block kit and ported heads and use that. i think my biggest concern right now is the rear end handeling the amount of power. i know that driveshaftshop.com has thier level 2 rear axel for the Z handeling about 500hp and the level 5 handeling about 900hp. my worry now is the drive shaft which i think driveshaftshop.com can custom make and lastly is that the inner CV axel isn't inclueded with either one of driveshaftshop's axel for the Z.

also, whats with this Targa top thing? anyone found a reliable shop to go to yet? seems kinda interesting and looks pretty sexy on the Z. i'll have a cusco 7 point cage going on so i'd have a bit more stability to the frame. i would go for te roadster but itlooks like crap with the top up and just something about an added 400+lbs to the curb weight that bugs me.

i'm actualy more set on an 05 really, but thankyou for your sugjestion. can't use Seibon's carbon fiber doors on the 06 and 07, apparently they are about 2 inches longer then the 03-05 models, i'm told this by seibon.

now how about wheel size? i'd like to use some Volk/Ray's TE37's, i was thinking 19's all around. 19x10.5" on rear *285/35-19* and 19x9.5" on the front *265/35-19* all with an offset of +22, is that doable without rub worry? rear's would be about a 3.7% bigger size diffrence then stock. the new wheels would be about a half an inch deeper then stock too, would that rub at all?

targa top weakens the chassis, if performance is nto important to you feel free to cut up a perfectly good car ???

as for the drivetrain componenets I've not heard a lot of complaints and unless you do a lot of shcok load drag launches which would twins a cut up targa chassis, the stock should hold up quite well, if you break somethign replace ti with a better part, and the R200 diff is opretty well bullet proof but the stock viscous sucks, you'd wand a clutch type, and if you really wanted all custom pieces use the alrger R230 from a Q45 or Z32TT then have all your aftermarket shafts made to fit
