300zx TT vs 350z HR

[NissanFairladyZ32]

Have any of you guys had any exp with the newer 350z HR?

how would a neraly stock TT run with one ?

my buddie want to run im running stock boost

- Jwt ecu-Jwt Intatke-downpipes/testpies W/stock catback- 1 piece driveshaft - twin plate clutch, new flywheel

The 350z is stock with just fujita intakes and 19inch rays G35 wheels

[Z32TT]

stock boost on a JWT ecu come on up it to 14 atleast then you should be able to pull him

[dozug]

lol thats not near stock.. i heard getting intake, ecu, and exhaust mod can bring 400hp for TT

[Z32TT]

you will be able to take him but increase that boost so he wets himself he wont bother to wanna race you anymore

[evildky]

lol thats not near stock.. i heard getting intake, ecu, and exhaust mod can bring 400hp for TT

that is crank HP with about 16psi of boost

a stock TT runs about a 14 flat quarter miles, an early Z33 runs a flat 14 as well, the later cars are a touch faster, only a couple of thenths, probably about as much as the pipes intake and ecu gave the TT, should be a pretty even race, the TT might edge out the Z33 without driver error

[NissanFairladyZ32]

i need a boost controller!

i heard the electronic ones have a turbo timer built in, is that true?

[Z32TT]

get a manual one, i havent seen one with a turbo timer built in maybe their is some with that function not sure, but no not every boost controller has that function thats a fact

in the near future im prob going to get the popforamnce boost controller not a bad deal

[ironwork]

manual boost controllers are a pile of dog crap. especially on our cars you need a dual electronic boost controller. especially if its a swap and you bypassed the boost solenoids. get a electronic one trust me. you get a better response you just dont turn pressure up like on a manual one. electric ones have safe modes and some have timers built in as well

a stock tt out the gate was doing 13.7 ive seen myself do 13.5 in 1992 my uncles bone stock tt. and its 400 at the crank yes but its closer to 14 psi. i have the dyno to prove it. although i dont have a quater mile at a track recorded yet i know z33 are barely pushing 14 even a hr z33. im getting a z33 soon so im not hateing on them but ther slow as hell out the gate. throw on a twin turbo kit and its all over but stock for stock not a chance. just my 2 cents

all the auto press came up with around a 14.0, one managed a 13.7 but you see similar variancein the Z33 test data so it's still withing the range of noise in the data

wow you managed to make the same power as other cars with 2 psi less......seriously 2 psi, anyhow your dyno sheet does no god withut boost logged as well, and if you have a dyno sheet with boost mapping please do post it up

mind tellign up where you did your engine dyno?

it's entierley possible for identical cars to ary by a few tenths or even a few hp, and when you are talking modified the same setup on a different car can vary but the general rule of thumb is that the stage 3 mods make 380 hp and thats supposed to be a 14 psi

[Z32TT]

stock for stock it can be pretty damn close the tt has it prob by half a car not alot considering twin turbo but the z33 is newer, a z33 is a fun car to drive i liked it but my tt with couple mods eats a z33 so i heart my tt more

[Z32TT]

btw not all manual boost controllers are crap their are good ones out their but yes i would rather get an EBC instead way better

[Z31toZ32]

Didn't you just say you were running 13psi? How did you suddenly return to stock boost? Did you take out the boost jets?

[Z32 TwinZ]

LOL you will pull on the Z33. I've raced to many not to know.

[ironwork]

wow your great at copying and pasteing info from auto press. and 2 psi is huge when your talking tenths and quater miles any real racer would no this. since you like to read auot press read some real world results on the net the z33 is slow and heavy the z32 wins everytime ive seen it i ve done it.

[Z31toZ32]

[NissanFairladyZ32]

Im pretty sure evildky knows what he is talking about.

[NissanFairladyZ32]

i know its got the jwt chip that is good for around 14 psi

but im not sure if that last owner put the boost jets in ... he said something about them but idk

how would you check ?

and how hard do the SRT4 Neons run ?

[billabong093]

Somebody just challenged the great Evildky.

[Z31toZ32]

The JWT chip is the best chip out there, and it is good for a full 14.5psi. The chip itself doesn't change the psi though.. it just adjusts the air/fuel so the engine can safely boost up to that level. The boost jets come with the JWT chip and need to be installed to actually increase the boost. I suppose an unprecise way of checking would be to floor it on the highway and see where the boost needle rests. If it is stock, it will stop about 3/4 of the way indicating 9.5psi. If it has the jets, it will be buried and you probably won't see it. If you really want to check 100%, you'll probably have to physically verify they are there. You can follow an FAQ on how to get to them on one of the tech Z sites.

[Z31toZ32]

Oh and although they look stupid and are nothing more than a Neon, the SRTs are fast, and can be simply upgraded to be quite fast.. just like our Zs. Make sure you are running the full 14.5 psi before you take one on.

[NissanFairladyZ32]

Update, he told me the boost jets are in, but he said the boost is never consistant he said it could boost up 11 or 12 one time and another 13 or 14 so i guess i need an aftermarket boost gauge lol

[Z32 TwinZ]

so i guess i need an aftermarket boost gauge lol

Yea i picked up a boost gauge just to be on the safe side. I went with a nistune chip and put my own tune on it. Im running .035 welding tips, which put outs 16psi. I heard detonation right away, but if u dont know what to listen for, a boost gauge will tell u right away. i put the car into safety boost for the time being until i can get some .040 and .045 tips and test them out. You want to be right at 13-14psi with boost jets, if you are right on 15psi, your running the chance of having a boost spike which will put u over 15psi and will cause detonation.

[Z31toZ32]

dude the max boost IS consistant, the gauge apparently is not. The jets that are in do not magically change size.. they are pre-drilled welding tips that trick the computer into thinking it is not bossting enough so it leaves the wastgates closed and hence builds more boost.

anyways if an aftermarket gauge might not be a bad idea if yours is inconsistent. just make sure not to do a rice-tastic install.

[NissanFairladyZ32]

Having this TT, makes me feel like my NA's were just a POS .. lol

You put so much into a na a get nothing in return

i made a mods to date list for the TT

-1999 Jspec Headlights -1999 Jspec Taillights-Jim Wolf Tech Intake W/ Hard Pipes - Jim Wolf ECU @ 14 psi - Boost Jets @ 12-14 psi- Downpipes - Test pipes- OS Giken Twin plate clutch- Lightweight Flywheel - Unorthodox Under drive crank pulley- 1 Piece Driveshaft- Aftermarket Radiator - SportMax 962 wheels 18.5F, 18x9.5R- Stillen GTZ Front Bumper - Nissan Fairlady Z Hatch Decal, Twin Turbo Decal

i should stick with the HR for sure

[evildky]

wow your great at copying and pasteing info from auto press. and 2 psi is huge when your talking tenths and quater miles any real racer would no this. since you like to read auot press read some real world results on the net the z33 is slow and heavy the z32 wins everytime ive seen it i ve done it.

http://www2.zhome.com:81/History/zcarperf.htmlscroll down the the Z32's you'll see 2 reported 13.7 second times, one from the 91 model and one from the 92 model, both suspiciously from Car and Driver magazine, and note they tested the 90 at a 14.1 and the 93 at a 14.2! so can we agree that there is a certain amount of noise in the data? and that a true stock et for the TT should be around 14 flat (this is a give or take as the results vary magazine to magazire year to year) keeping in mind these tests were done on stock tires which were I'm sure pretty good street tires for the time btu by todays standards are junk

on the topic of 2psi, my point was that unless you have the boost mapped dyno run you are merely reporting what you believe to be the amount of boost that you are running, my sport 500's came "preset to 12 psi" do you think thats the actual amount of boost I'm making? might be a little more might be a little less, ever heard of boost creep? evne if you have it set at 14 chances are good that you'll experience at least a 2 psi creep under heavy load, to the 2 psi again fals int the area of noise in the data

I call BS on your dyno, i don't believe that you put the engine on an engine dyno so your "400 hp" is purely speculation, if you know of a shop with an engine dyno taht has a jig for the VG30DETT and the necesarry provisions for piping and turbo's I'd like to know about it otherwise I call BS

stillen created the "stage 3" package and they calim their intake, exhaust, ecu with boost jets yeilding about 14 psi makes 380 hp at the crank, and I take their work over your uncle any day

so yes it's possible to run better than reported times with better than stock tires, and the same goes for the 350Z, all of it's testes were done on newrer better tires but with far less sidewall and less suited to straight line acceleration so both cars could likely save a couple of tenths on tires alone!

the OP stated the Z32 was basic stage 3 minus the added boost, this means it's likely putting aroudn 260-170 whp (keep inmind not all dyno's are created equal, so you might get a higher reading on a dynapack, and curb weight is around 3400 lbs

the OP stated the Z33 HR with intake, in stock form the HR should put down arond 250 whp (the stock et was 13.7, about .2 faster than the early Z33), and the intake should add 5 hp or so, the curb weight varies from model to model but shoudl weight around 3200 lbs, a touch lighter than the TT or if it's a loaded touring it'll be pretty dead even on weight, and if it's a convertible it's about 400 lbs heavier and the race will be over befre they get their top put down

if you wanna know how fast you car is take it to a track, if you want to know how powerful it is take it to a dyno

don't quote power to ET without a timeslip to back it up, and don't quote Hp without a dyno to back it up

my fingers are tired

[NissanFairladyZ32]

I ran the car wide open throttle a few times and its hitting 13.5 not quite 14 every time

so it has the boost jets

btw the 350HR is a base model, no traction controll or anything but its lighter 6 speed

This is the updated mod list

1999 Jspec Headlights -1999 Jspec Taillights-Jim Wolf Tech Intake W/ Hard Pipes - Jim Wolf ECU @ 14 psi - Boost Jets @ 13.5 psi- Downpipes - Test pipes- OS Giken Twin plate clutch- Lightweight Flywheel - Unorthodox Under drive crank pulley- 1 Piece Driveshaft- Aftermarket Radiator - SportMax 962 wheels 18.5F, 18x9.5R- Stillen GTZ Front Bumper - Nissan Fairlady Z Hatch Decal, Twin Turbo Decal

[evildky]

headlights, tail lights, bumper cover and dealcs are nto mods, they are arts and crafts projects

and the wheels are likely heavier than stock and have less sidewalla nd mroe difficult to launch

without the wheels, the stakc 3 mods should put the car right around a 13 flat int eh wuarter, the Z33 with the itnake should run a mid 13, so you'll lead him by about half a second, now to the track and tell up how it plays out

[NissanFairladyZ32]

yeah ill hit the track soon

i know the stickers and headlights dont help, i just copied it from a word doc i made .. lol

Is it normal for the tires to start to spin before hitting 2nd gear ?

[evildky]

normal on stock tires, traction is a larger issue for you because of your larger wheels, the idea is to get traction nto slipping, genrrally smalerdiamter wheels with alrger diameter wheels, 15's will clear stock rear brakes, this gives you lots of optiosn for crag wheels and tires, and they tend to be a lto lighter than aftermarket 18's
