So. Skyline or Supra?

[liner33]

Terrible 60fts!!!!

106mph terminal should be closer to a low 12 than mid 13!!!

13.572 @ 106.38 mph Peter Sharp 60ft 2.224 (auto) UK spec
13.597 @ 105.6 mph Supradeek 60ft 2.216 (auto) JAP spec

Yeah, that looks like a 50bhp difference.

Quarter mile times are related but different to the engine power output.

The power output of the UK model is demostrably higher than the JDM model for the reasons I stated before. Quarter miles times have many different variables that can influence the elapsed time and terminal speed.

Hope this helps a little

Terminals are related to power though, or have the drag forum got that wrong? If the UK's were 'vastly' more powerful why is this not reflected when club members go on trackdays, RWYB's, dyno shootouts or simply driving together, even the people who have owned both have said there is no significant power advantage. Or is everybody else wrong but you?

Hi Gazboy, I was speaking from personal experience of being the first and possibly the most experienced Supra Tuner in the UK, with possibly one of the most accurate dyno's in the UK.

I was just trying to point out to the OP that the UK and JDM models are demonstrably different in many ways

Sorry for the OT.

[TDIPLC]

I'm only going from our dyno evaluation data collated over the years Gazboy.

Lets agreee to disagree on this point

The UK model Supra is different to the JDM model in many ways, but as far as the engine concerned it has higher performance camshafts, larger turbochargers, higher flowing exhaust manifolds and different engine management etc and is rated at around 50hp higher than the JDM model.


Hope this helps a little

The compressor and exhaust wheels on a JDM are actually larger, although the UK uses a larger A/R. It also uses a slightly higher lift inlet cam 8.25mm as opposed to 7.8mm, 233 as opposed to 224. I am also not convinced the cast manifolds vary enough to have any significant difference. Have seen a few stock JDM TT's dyno'd there is nowhere near a 50 bhp difference between the cars.

All IMHO of course.

Supra for me man...

[Riknos]

Buy a Supra.
More likely to get laid.

Without the shopping list

But definitely not this kind of thing...

I actually like both. The second one isnt that OTT on the kit.
That was your point right?

[Marf]

If the black car had the bonnet off the grey car that would be just about ideal in my book.

[v8 jago]

My mate has been toying with the idea for months asking 0000s of questions and doing lots of reserch on the two and he says that skylines have weak bottom ends and cost £0000s to put right, On the other hand the supra is the strongest in every way by far. Both capable of being very quick cars. I would say they are both great cars to own so it would be to what the individual wanted out of the cars. Personaly i would be happy with either, But my mate has just ordered a 6 speed manual twin turbo supra.

[liner33]

mmmm dunno about weak bottom ends a guy i know had his RB25 up to 487hp at the hubs and it was fine on stock rods and crank, unfortunatly 500hp ath was a little too much.

GTR bottom ends are meant to be ok for 600hp and are a popular upgrade for big hp RB25's.

Hi Guys....I`m the guy who V8`s on about...I have done years of research on both cars...And,Not just from earsay,I spoke to the top guys in the business on the skyline becouse i did fancy one (Badly)..And,Did`nt want to believe what people were telling me in the normal world....So,I went to the top guys for advice...(Whoe`s names shall remain nameless)...And,I was told off the record that Quote"Yes",Skylines do have a problem with the lubrication of the bottom end...And,One owner i spoke to (After i got shot down in flames for saying skylines have a problem that obviouslly the owners would rather not admit)Contacted me to say....He religously changed the engine oil and filter every 2500 miles,Allowed the car to warm up and spool down after every trip...And,He stripped down the bottom end to uprate the internals and at 42,000 miles both no`s 5 & 6 big end bearings had worn through all the rest were good as new....But,Stated he could do no more to look after his engine than what he had already done.....
Now,I do understand that if mods are done and the car has`nt been set up correctly IE:- running lean...Its goodbye to any engine.....But,Reports from the specialists on the Supra Have been nothing but praise on the engines strength/Reliability.
Both of the mentioned cars are absolute icons in the tuning world...And,I`m in no way shape or form dissing either make...Going by years of gathering info on both cars I`m going to try the Supra.
I also understand If regular servicing on either car can alter the record either way...But,It does seem like for like the Supra engineering qualities do shine...

what you mentioned is certainly no secret amongst gtr owners.
The inherent oil problem with RB26's only becomes apparant at the top end of the rev range, repeated abuse up the top of the revs will no doubt highlight it by means of spun or rattling BE bearings eventually, but it's not a problem on every car, and a tomei orifice will ensure the head doesn't suck up all the oil if it's a concern.

Yes STU....This was also what the specialists told me....The one i was talking to...Had 7 in for builds...One as low as 36,000 mls....So i asked him...How can i avoid or get a car that has`nt got the problem starting....????His reply was...Get a car with a recently built engine with all the supporting documents...He said other than that...Its a lottery...
But,Yes i`m with you on this one stu...When i was doing work on rally cars with various guys....It was a well known fact...That,Everytime an engine reached 7000 rpm it took 1000 miles from the engines lifespan..Although,This has now been proved incorrect with the Honda`s revving to 10,000 rpm`s....and,better quality/tolerances/Materials/oils being used today...

Its not secret that rpm kills engines, perhaps thats why the RB26 bottom end is fine in big hp RB25's as they rev lower to to valvetrain design

I always used to set my drag bikes up to deliver max power lower than some of the other guys , it used to rob me of 10% of peak hp but gave the engine a lot longer life

[paul_k]

Having owned a Supra for 5 years i can absolutely recommend it.

From memory the Jap import TT has 318lb ft torque against the UK cars 315lbft, which is partly why the jap car isn't that much slower despite the 280hp rating... and yes they really are 280hp...

Total reliability, bomb proof engines great styling one of the best dashes in the business just have to watch the suspension rubbers as handling can get very dodgy when these are worn.

How does this grab you:

Yeah, I like that actually...

I need to try out a manual and an auto when I get a bit of time really. I'll get out to a meet, or go and see a couple.

And thanks everyone for all the comments. Very helpful. PH really is an absolute mine of info on any subject.

[Ro_Kopite]

The Supra bottom end is very very strong, the compression on mine is still strong with a single turbo upgrade although it's not been pushed as far as it can go. Incidently... *shameless plug* http://www.pistonheads.com/sales/222977.htm

Whatever you go for between the Supra and the Skyline, both are great cars!
