Hello again, I say again as I joined this site just over 2 years ago when I was thinking of buying A 300 then. In the end I bought a Celica GT4 ST205 which is now over 300bhp, trouble is I want more power and it's just not worth the money to get it IMO so I think it's time to Upgrade :D

 

I've had a look through the buyers guide etc and I'm going round taking cars for drives ATM just to get a feel for the good ones from the bad ones so to speak. Got to sell my four yet but I'm in no rush so thought I'd start hanging out here and learn a bit about the car I'm planning to buy.

 

I'm after a SWB TT manual Targa, which as far as I can work out are rare as hens teeth, but I would settle for a LWB one if the condition/price was right. Any way enough waffle, If i see your stand at Japshow, I'll be sure to come over and say hello.

now THAT does sound like a good idea :) when is it?

5th july mate look at the thread.

Put my name down on the thread :) what time is it though?

most people try and get there for 12 mate

Cool, I'll see you all there then.

To Obtain Higher BHP the best bet will be for a Lightened Flywheel and perhaps a CF Prop!Rotational Weight being reduced will see BIG changes in BHP! Engine will become more responsive and snappier too :)

 

Thats your best Bet for 400bhp without Stupid Boost which is a bad idea!

 

I'm after a SWB TT manual Targa, which as far as I can work out are rare as hens teeth, .

 

i'm selling my swb tt manual targa...left my mob number on a previous post call me whenever

went out in another TT today, a MUCH nicer example, still wouldn't buy it as it had some small rust issues and ideally I'm after something in near perfect condition. The biggest let down was the performance again though :( which had led me to need some question's answering.

 

1. What's the weight of a 300?

 

2. How much torque does the engine make

 

3. What pressure can the turbo,s be safely wound up to?

 

4. What's the 0-60 time?

 

Hopefully the meet at Halfway house can restore some faith into me :)

a 300+hp gt4 will be much quicker than a stock 300zx

 

The 300zx is 280hp and around the same torque and will have a 0-60 in 5.5 so the same as a stock GT4

 

Not to sure on the weight i think they are around 1700kg (might be wrong)

 

One of the main reasons why the gt4 will feel so much quicker is down to the power delivery. like nothing nothing BANG all your power at once. where as the zx is smooth. which this car is all about

 

Its not a rally beast its a crusier

 

With very little money thrown at it. it will woop the gt4 all day on acceleration but still feel smooth.

 

What you will need is

 

Injectors

Turbos

Intercoolers

Lighten pully wheel

1 piece prop

NA diff

Lighten fly

Boost controler

and a remap.

 

Then you will have your self a very nice motor :)

Thanks for that, just the info I was after. I knew it was a bit harsh to compare my four to a stockish 300, but to get the four to how it is now has been pretty easy, so wondered how easy it would be to do similar mods to a 300 and what it's effects would be.

 

1700kg though? I though my 4 was heavy.......

Alot of use had the same mods and we went for a rolling road. 90% got around 330hp

But others on the site have managed to get much closer to the 400hp mark so as we know dynos are not very accurate.

 

To get it to the 330ish you will only need about £500 if that.

 

If you are after big gains then there is the supra. 400hp is very very easy with the bup

Also the weight of the ZX is 1600kg :)

turbo boy, both my sons have gt4s and when we have been out for a drive, neither of there cars can get passed my zed from standstill. When we reach 80 i start to loose them, and my zed is only an n/a.;)

Granted RR's can vary some what, but I know some cars that had the same mods making very different power at a GT4 RR day I arranged recently.

 

The trouble with Supra's are they are a bit bland and ugly IMO.

I think your boy's need to push the pedal all the way down then ;) Are they in ST205's or the older ST185's with pop up head lights?

they both have st205's, i have driven both cars myself and yes they are quick,but standard they are not quicker than my n/a.:)

SWB model is considerably lighter weighing in at around 1500kg! Take out the A/C, Spare tyre and some lighter seats and right there you will save around 50kgs across the whole car!

As stated the Zed is very smoooooth power delivery and is why people think they look slow especially on Tracks, but for everyday usage its more than enough power if you want to mess around :)

 

Simple mods also (ECU Upgrade, Boost Controller and New Exhuast system) will put you around the 330bhp and with a SWB at 1500kgs your Power-Weight per tonne will be around 225bhp per tonne

 

where as your GT4 weighing in at around and 1440kgs and at around say 300bhp with mods you can see there is little difference Power to weight wise as this will be at 211bhp!

 

So in actual fact on paper the Zed is faster! Being RWD the power delivery will seem strange compared to the 4wd system of a GT4! (Certain they are 4WD)

 

So there you have it! It may feel Slower but probably isnt :)

 

Also Note a LWB Zed (1600kgs at 330bhp) will be around 210bhp per tonne so is matched to the GT4 so if you get the big zed with stock weight you will be as fast as your old car :)

Plus the gt4 will have a greater transmission loss. I would say it would be close upto say 80/90 then bye bye gt4 :)

I'm not calling you a liar, but I do find that a little hard to believe, although saying that if they're running them on normal unleaded and not super it'll cause det and the timing will be retarded. Uk spec cars also have less bhp (236) as opposed to the JDMs 255bhp, but I've seen stock GT4's make any thing from 230 to 270 BHP on the dyno before so who really knows?

That is true, the power delivery is a lot smoother, but I do kinder like the viciousness of the four's. I think some of that is the fact it is 4WD as it allows almost full power launches if you're careful ;)

 

Power to weight ratios are also comparable so what I'm looking forward to is driving/going out in a modified 300 and then seeing as the 2 i have driven have been almost stock. It's really the EBC that transforms the car as once it is set up correctly you can make the turbos earn their keep so to speak.

 

Plus the gt4 will have a greater transmission loss. I would say it would be close upto say 80/90 then bye bye gt4 :)

 

Stock for stock I'd have to agree, mine does pull VERY hard to way past the speed limit though, all this talk is making me want to put all this to the test on the 1/4 mile now :hyper:

Something's not right there. The GT-Four is near TT pace under 80mph and would easily kill a NA Z.

 

0-60 is a good second to a second and a half quicker than the NA Z. They have more power, lighter and 4wd grip.

Edited June 17, 200916 yr by Yowser

Most Z's get around 350-370 hp with 1bar boost, Induction and Exhaust, but 400 is obtainable with just bolt-on's. Its above 400 that its starts to get expensive.

In all honesty do not judge the 300zx on one test drive. There are so many bad examples out there and there are so many that are running around in Safety mode, most likely quite a few members here will be in safety mode since they got the car and do not realise. Have resolved safety mode issues for owners many times and they are always shocked by their cars new found performance levels.

 

I would say over half of all the Z's I have driven over the years would of put me off them for life if I did'nt know what a Good example is like.

 

280-300 bhp (depending on which specs you believe (listed as 300 in the U.S and 280 in Europe/Japan, but no reasons for power difference)

280 Ib/ft Torque

 

1580-1600kg for LWB

1490-1540kg for SWB

 

Turbos Can handle up to 17/18psi (but dont expect them to last long at that boost), and your limited by the stock injectors at around 14-15psi (1bar).

 

4. Car and Driver magazine recorded a 5.2 secs in a SWB Z, however 5.5 - 5.7 secs is around about typical tested figure.

Come and buy mine, it runs perfect i can assure you, if you dont find mine fast enough then i dont think you should buy a zed

I've driven three now, and the most surprising thing is none of them were using super unleaded, all of them were using the cheap stuff and at high revs they were getting det :(

 

I must admit that I am looking forward to the halfway house meet, hopefully see some decent ones there. A standard ST205 GT4 will hit 60 (officially) in 5.2 sec, but i know mine and plenty of others that can do it in the low 4's

 

A N/A 300 wouldn't stand a chance against a ST205 IMHO, and I think a TT would be given a run for it's money (stock for stock) if I'm to judge it by what I've witnessed.

 

I would never of even bothered to try against a TT if i saw one but now, I don't think it would be left looking suprised ;)

 

Anyway, I hope you right and they've all been in Limp mode, cause i love how they look, but performance is more important to me, and right now, the four is leagues ahead in that department.

Dont want to sound rude but tbh it dosnt sound like you will ever be happy zx.

 

It just sounds the wrong car for you. why dont you just tune the gt4 up if you are already getting 4sec /60 :confused:

I don't find your opinion/question rude ;) like that cockney bloke from the BT ad said:

 

"it's good to talk"

 

The Four has reached it's maximum now without resorting to forging the engine, the only things i could do now would be a front mount intercooler, bigger injectors and fuel pump, ECU upgrade and maybe water injection and that would only gain me another 30bhp (reliably anyway)

 

Maybe your right and a 300 isn't the right car for me? I'm willing to give it a fair crack of the whip though as I've always wanted one. Perhaps I've grown to expect too much from it though? Time will tell I guess, the one I saw today was very nice to look a,t although needing extensive tidying of the body work, was a step in the right direction so to speak :)
