If we are playing 'find the link' then can I direct you to
http://www.tdi-plc.com/suprafuelpumpdata.html
Have you actually seen a UK spec pump next to a j-spec one?
Tell you what, why not give some people who know what they are doing a call, give TDI a go from that link, they actually did the testing. Or give www.jpsmotorsport.com a call on 01908 367100 and ask them if theres any point in changing the j-spec fuel pump for a UK spec version.
Its always nice to see stupidity in the face of such evidence so feel free to find another web link to try and prove something you know nothing about.

LOOK at the flow rates and do the maths with respect to injector flow rates. The nominal fuel pressure around 2.8 bar (40+ PSI) in a typical stock Supra TT will mean that pump (according to that graph) is enough to provide just 200 HP at the crank.
Now WHAT J-spec supra was that pump from? N/A or Turbo? How can you schmucks tell from that graph?
Just how does a J-spec MKIV "320" HP supra use a lower flowing fuel pump than my standard MK3 pump?
Your stupidity makes great Christmas comedy!

Simple - people who own the cars vs someone who doesn't.
There are plenty of Supra RZ owners who have made 450 + HP with stock fuel pump. The simple bottle neck is the 430-440 cc injectors. A 550 cc upgrade is common, NOT the damn fuel pump which does a fine job anyway!
Someone here with a RZ Supra keep their stock fuel pump and go for 550 cc injectors please! It's the RIGHT way for more power.

Put foot in mouth, jawa...
I used the 2nd link to prove the gearing of the J-spec, not the US/Euro models. The 3.133 final drive was probably a mistake in the 2nd link. All 3.27 for all manual TT's regardless of spec, here's why...

Perhaps when you grow up you can come back for a chat, until then I certainly wont bother replying to your drivel.

It's the same Denso fuel pump, twit.
I know you have a problem admitting your mistaken here but there is a great difference between the 2 pumps , even just the physical size , go to mkivsupra.net and look in the tech bit at the top of the home page in the upgrading injectors section and you will see what i mean , yes the 550 inj will work on a j-spec pump but not as well as they work on a uk or walboro pump , trust me dude the pumps are different and at the end of the day why skimp on a relatively cheap part ie the pump when you are spending fortunes tuning your car for example i can prob run my single turbo and 850 inj. off of 1 Walboro pump but im not going to , it will have 2 pumps 2 lines and 2 filters , WHY because it will cost under £200 to fit the 2nd pump and i dont want to melt an engine thayt will cost 3K to rebuild , its common sense , go look at that article and you will see that you are very wrong (theyve even got photos )

LOL, I give up on you, even your fellow mkiii owners have said you are a troll. How do you know they have made 450 hp +...maybe they made it on those rollers you distrust so much, the same rollers that show the stock imports with 300-310 hp.
Again, average trap speeds between the standard J-spec and Export Supras are as of follows. 99 MPH (J-Spec) vs 104 MPH (Export)
Give up, Branners. Owning a MKIV does not absolve you from the responsibility of knowing what you are talking about.

whats the big hang up over stock supras? i dont know many people who would keep a performance car in stock trim. i dont think i could go back to stock power as it would feel too slow. the supra is the first sports type car i have modded. i aint done too bad with the so called crap j spec car. with smaller injectors and no electronics.
i used to have a mk3 supra turbo and seeing them running 15+ seconds is a bit of a joke. even astra turbos run high 13`s.
cars look good on paper but how many people could tell if it has 280bhp or 326bhp
just have fun in what car you own. i used to think my mk 2 astra gte 1.8 8v was fast, well it was at the time or so i thought.

"Just how can a "J-spec" fuel pump with a flow rate of 75 litres Per Hour at 40 PSI be able to provide the fuel supply for 280+ crank Horsepower? "
So am I to gather now that the j-spec fuel pump isn't even good enough to produce the 280 horse that you previously have been banging on about it producing then???
Are these specs you are on about now the ones for the N/A version that I own? I too have been scouring the net for info about my machine and have so far found most of the information available very confusing, and often directly contradictory of other supposedly reputable sites and of no real help at all, which leaves me going to someone that has previous experience and real time knowledge of these vehicles.
Like someone said earlier the "stock" vehicles don't remain that way for long in Japan even as far as the delivery specs all being different! There doesn't appear to be a standard with the j-specs at all. My motor as an SZ N/A is not meant to come in aero format, its not meant to have aircon, or electric drivers seat, or the CD player or even the spoiler according to toyota japans wesite information. Also my motors brakes aren't the origionals either. If you look at the auction sites most of them have suspension, wheel/tyre, and exhaust mods and thats just what you can see. So what I am driving at is that if toyota are modding the cars before they leave the showroom and then every other Tom Dick and Yoshi are changing them even suggesting the term "stock" is pointless in respect to j-specs.
Trying to make an argument about "stock" j-specs seems very much like arguing that black is better than white when someones added yellow and blue along the way.
How do you know what spec of car the people that generated all the information you are quoting actually had? A lot of the information you are quoting is coming from third party sources.
To make any of your argument even a bit valid you would have to find the original specs for a j-spec (obviously at this point you would have to decide which one of the specs to go for sz,gz,rz?) and decide on the optional package you were going to plumb for and then most importantly find that car somewhere (as easy as finding a virgin in Essex lol) and pit it directly against your UK variant (sorry not YOUR UK variant obviously because you don't actually own one!)
To answer the mans original question the only thing I can say is drive all the cars you are considering. There are a lot of traders now that deal in import cars the one up at keighley has an impressive stock list of gto's fto's skylines supras pulsars scoobies you name it they have it. There are UK motors available to drive in auto trader on a regular basis so getting a test drive in one shouldn't be difficult. There are also meets with these cars like for instance in Southampton on the 11th of Jan there is a supra meet with over 30 cars showing up, other makes are expressing an interest as well (shameless plug here http://www.mkivsupra.net/vbb/showthread.php?s=&threadid=14888)
so get yourself along to one of those. If you are a real petrol head then go to santa pod or a race circuit on an open day and see some of the cars in action. Personally I bought mine because it was an aero top with ridiculously low miles on it and was good value for money. I'm no street drag racer I just like the look of the car (And no I do not cut hair for a living). I recently had the option of buying a second supra UK model and didn't even though it was a good price purely because it was white with cream leather. The standard specs on it were well above the SZ I have but the roof doesn't come off UK cars and the miles are higher. So horses for courses really just don't go bringing the donkey cosworth with ya hey!

I give up !!!!!!!!!!!!!!!!
I'm still waiting for someone to explain just how a graph courtesy of TDI engineering showing that a 75 litre per hour pump is sufficient for 280 HP or over on a J-spec. Perhaps J-spec components have mystical eastern powers that make the car have exceptional abilities whilst defiant over the laws of physics that apply on the rest of the world?!
dangerous brain - Waffle! LOL
You could have made 1 paragraph that would have expressed everything that your amusing essay was trying to convey. (This also applies to ScoobyJawa, Branners, Trollhunted and WRX_280) Here's an example of what you could have said...
"I don't care what the facts are for a MKIV J-spec, I just don't want the facts to clash with my misconceptions that J-specs are superior because I own one."

No one said anything about superior - except you harping on about the UK. They are both superb cars, we were simply stating the UK is not faster as people are led to believe. Even UK owners have told you there is no difference but you blindly ignore what you don't want to see. When people post up links to proof, you call them crap or lies yet you think your links just so happen to be gospel from the lord. LMFAO @ you.

Obviously if you'd rather sit around waving graphs at it thats up to you.
Like I said previously I bought my car for the looks of it I expect the Evo would handle better and in any given road use be a quicker and safer car than either UK or j-spec supra.
This thread started with a guy asking a question about which of two cars to go for and so far all he's gotten is a load of injector specs and pumps.
If the only response you can come up with to practical advice is

He s like a truculent teenager , he wont be told , i bet he's looked on .net at the link i told him too and is now trying to think of something to make himself look clever , anyway hes obviously outside with his MK3 attached to a rice pudding trying to pull the skin off it , perhaps he will turn up next year and take that grand off me but i doubt it cause if hes tuned it the car wont make it down the strip !!!!
#207
Listen you moron from the TDI graph a NEW uk pump flows 168 ltr @ 3bar and a used J-spec 66 ltr,so why did you put that link as Toyota obviously thought the 550 inj needed a lot more fuel than the J-spec pump can provide . the used jap pump had only done 2/3 the mileage of the uk so thats a fair comparison . You really are a thick little shi**te arent you .

if you understood anything about cars you would have bought a real one !!!!!!!!!!!!! What presure do you think these things run at ???? static is 36 psi rising with boost or are you running at 8 bar forcing fuel thru the injectors to satisfy that powerfull beast of yours , you really are a joke dude , good entertainment though so you keep digging that hole , this is providing entertainment for the whole of .net !!!

BTW im not arguing that the j-spec pump can support x amount of HP im just showing everyone that you are wrong by saying the J-spec and UK are the same !! but you know this now cause you looked on .net and realise that you really do talk out of your **** , i mean you posted the link that showed TDI (who youve slagged off) testing a uk and a Jap pump , thats clever when you were saying thay are the same pump , like i said you amuse me little man so carry on .
