what should i do next?

[tyrannix]

got the full airflow package (intake, equal mani, full exhaust), cams, arp head studs, tomei 1.5mm head gasket, light flywheel, clutch, short shifter ...

edit> forgot to addi have now a hi flow fuel pump, FPR, Apex'i PowerFC ,

and my current turbo is (i think) an S14 t28, also have a GTI-r T28, not sure which will go on first

and 720cc injectors in the near future (with q45 MAF and maybe TB)

I say driveshaft. Plenum is a close 2nd though.

[float_6969]

What kind of braking system do you have on this car? A vehicle with this much power is gonna need some good brakes. You'll also get better acceleration, handling, and braking if you lower the weight.

For the all around improvement, in every aspect of the vehicle, go for the doors.

[tyrannix]

z32 fronts (from a 98) , soon to purchase z32 or r32 rears .. have braided stainless s13-z32 lines already (i think theyre the projectsilvia ones)

edit> and its a silvia front (-25 lbs) and the sound dampening is out ... scraped, using 3m adhesive remover to get the gunk off... works like a champ.. im going to actually weigh it.. i hear anywhere from 30-45 lbs

each one of these will help out.. im planning to get all of them, the plenum or driveshaft is what i was leaning towards, because it would be easeist now... before i drop the CA in it .... im dropping the Diff to put in the torsen helical.... perfect opportunity to slide in the driveshaft....

but then installing the plenum will be easier with the engine out as well, i havnt even installed the stock one yet (still waiting on oil pump for final engine assembly)

and if i get a BB GT series turbo, its going to be T3 flanged.. so ill need to replace my awesome equal length mani for an EW one ..... or i guess i could get an internally wastegated T2 flanged >=t3 sized turbo .. its probably going to be a gt3071 ... i mean i could do a t3/t04e, but i want stupid low-spool hayabusa-acceleration and still be able to break 400 RWft/lbs

the doors are kindof a dilemma in themselves... like... do i paint them? if i dont, then a shaved door handle kit is out.. (shaved door handles more for theft-deterrence than slick points... the slick points is just a bonus)

imagine you are a car thief... you see a nice looking car.. but theres no door handles, or steering wheel (quick release) .... that should be enough to deter you... if not, other fun tricks like instead of an alarm, a wireless fuel/spark or ecu power cut ... any of those 3 would prevent the car from running period, even if somone did break in

i personally find shaved door handles to be the weak-sauce, i hate em..

and nothing will stop a determined theif, chances are if they want your car, they will hook up a vicegrip or something to the steering shaft to steer the car (thats if they even drive it) after they broke the window or simply used a hanger or somethint to pick the lock..

but anyway, i say save your money and get the GT2871R, GT28RS or HKS GT-RS turbo, keep your "super" turbo manifold, and get the HKS actuator, 550's and some kinda S'AFC II or the new E-Manage..

Imagine you are a car thief with a tow truck or flatbed, you look and see this stuff, and say to yourself, "Damn, I can haul this car away in 4 seconds, screw a steering wheel, I can get some good money off the parts."

[tyrannix]

obviously, any hardcore car thief is going to get what he wants

its a deterrant, keeping the majority of people and would-be thieves away

im not saying any of this will *STOP* a car from being stolen.... in fact, forget any of what i posted about that, its just going to hijack the thread into a car stealing thread

[Dattebayo]

Vote #2 for the doors. Thats alot of wieght you are going to lose right in the middle of the car where it will help the most.

Damn... are they really only 15 lbs?

[tyrannix]

yeah, 15 lbs each, but then you have to put all the window junk, and door lock stuff in (door handles... mirrors, glass, regulator, striker plate, all that crap)its 15 bs of carbon fiber for each door shell..... which even still is *alot* lighter than stock

[float_6969]

who said anything about windowns? LEXAN THAT SHIZIT!!!

[biosehnsucht]

I vote for brakes

after fixing my #2 coil the other day and finally realizing the full power of my car (such as it is), the first time I tore off down my street all I could think was BRAKES BRAKES HIT THE ****ING BRAKES OMFG

(my #2 had been dead for who knows how long, and I didn't notice until someone else pointed out it seemed to be missing because to me it ran too smooth.. it was smoother missing #2 than my old KA was on all 4.. gg's balanced rotating assembly)

as for doors..I thought removing weight from the ends of the car (reducing polar momentum or whatnot) was more important than the middle, since it has more effect on the stability of the vehicle cornering-wise

[float_6969]

That is correct, but in this case, there isn't much that can be done with the 240 in that department. Perhapse removing the gas tank and relocating it where the back seat currently is. So with that in mind, decreasing the TOTAL weight of the car is still a step in the right direction.

[biosehnsucht]

hehe yeah and from those #'s those are LIGHT doors

granted, I'm not sure I'd want to remove my beefy doors for a street car.. and I like my power accessories, do those doors handle full blown power locks and windows and speakers ?

[tyrannix]

yeah, the doors allow all factory power equipment

and i already have z32 brakes (with braided stainless lines) i have fronts+rotors, on the "soon to purchase" list is rears

and it is alot of weight to save.... but rotating mass is better to savetheyre both really good upgrades

you know any places that are producing S13 lexan glass replacement? or you just saying custom job it?

[81na ZX]

who said anything about windowns? LEXAN THAT SHIZIT!!!

Windows! We don't need no stinking windows!

While your at it though, see if you can compare the manual weight to the power weight.

[float_6969]

no, you'd have to have the lexan custom done.

[tyrannix]

i *could* compare manual to power weight, but its moot.... im not putting on manual windows... same as im keeping AC (going to do a working digital conversion too) and i will have a full interior when my car is done... all the weight savings will be hidden, and not tacky (its a street car too afterall)... except i wont be putting the automatic seatbelts back on... i have A-pillars from my silvia, and 4pt harnesses.... and if johnny law requires, i have the manual seatbelts from the silvia as well i can put on

[tyrannix]

hmm.. kinda turned out as i was thinking... almost

the plan is solidifying in my head now... definatly the driveshaft first... as its the easiest immediate improvement i can make....

then i will get the CF doors... and while im at it, ill get some lexan or plexi, or whatever other transparent polymer windows.. and do that conversion all at the same time... and ill post all the weights and differences and weight savings of the carbon and base sheet metal doors.... and the glass vs polymer windows (and all the other junk inside a door..... central locking mechanism... which i really could cut out... but i like it .. power window regulators and door handle/lock mechanisms

then next after that i will probably get the plenum...

because i want a really hoss turbo.. and the longer i wait, the less it will costi want a ball bearing center, and ceramic turbine and compressor wheels... i want rediculous low spooling with stupid high flow and power output... until i can have that ill make due with my t2 flanged guys (maybe even switch to an external wastegate setup for the T2 turbos while im waiting for my perfect turbo to exist ... or just go with a standard t3/t04e while im waiting ... maybe i could get the t3/t04e and then just get the BB center and ceramic wheels ... hmm.... options, options, options
