I'm disagreeing with the Jspec times, not the UKs Interestingly that review also says the wheels are cast? I was always led to believe they were forged.

http://www.autocar.co.uk/CarReviews/RoadTestsData/Toyota-Supra-6-sp/200081/ 5.1 in Autocar I'm guessing they ran the tests themselves as they have a LOT of data on the car.

Ok, back to stock then. You can't redline a stock supra for a launch. You need to hold it just under the 4krpm mark to get a good launch. The difference between a couple of hundered rpm is the difference between bogging down and spinning up the rears on launch. Fine tuning the RPM that you launch at is obviously where the faster 0-60 times come from. Not telling you anything you don't know, just pointing out my thinking. Anyway, my point is that grip is still the limiting factor as with grippier tyres you can up the launch zone to say 5krpm to get a faster launch. This is my reason for saying grip is the limiting factor in the 0-60 times. Obviously the change into 2nd gear in a stock car won't get much slip so after that, IMO, the time is already set in stone. Now, bring that into the stock 0-60 time listed by toyota. You have managed a 5.5second 0-60 time on UK roads yet apparently Toyota couldn't manage that on their test track? The time from Toyota is a lie IMO and as they are 'official' times the real times will never be official. I firmly believe a stock TT in prime condition will manage a 0-60 time of 5 seconds in totally stock trim in the right conditions.... test conditions.

I have to disagree there though. The difference between Brians car and every other BPU out there IS grip. Granted it's all down to the setup of how he gets that grip, but that's the difference. It's the same with the guy that managed an 11.5sec quarter in a 6spd BPU. I can't remember his name but he is a member on here. Had no mechanical sympathy and really went for it. His 0-60 must have been around the 2.5sec mark the same as Brian. My point is that grip is what holds these cars back. You managing 5.5 on the road is very impressive to be honest. Toyota certainly won't have gotten their figures from road driving, it will all be done on test tracks. The difference is night and day, as you will know, when it comes to where you can slip the clutch and how much you can slip it by when comparing a road vs a prepped track. Edit: Just realised I missed out about Brians high stall. Obviously that would make a huge difference to how the car drives and to how well it launches, so obviously a stock TT Auto wouldn't be as fast... even with the suspension/chassis/tyres etc etc. The 6speed BPU I mentioned is probably more comparible to other 6speed BPU's than Brians would be to most BPU Autos.

I think Supraloopy does them mate, need to be a trader/hobbyist to take on work

Was that on the road or on a strip when you gave it a go? Yeah that's what I mean, the more power/torque the more chance of finding it hard to keep traction. It doesn't really matter if you are stock, bpu or single.... you will get very similar 60 times in stock trim chassis/tyre/wheel wise. Just look at what Brian managed on BPU when he could actually put the power down. Take away the BPU aspect of his car and put it to stock power/torque and he would still crush 5 sec 0-60 times as grip is the limiting factor... not power/torque.

Ahh, more tea Vicar?

No, I know that. It was one I came across quickly. I'm sure I've seen stock supra's managing 5sec 60s and 13sec 1/4 mile times. I know Jake managed a 4.9 in his BPU Supra. The argument could be made about the power being higher but it won't make any difference to the 60 time as grip is the restriction.

I think it was the other way around, the manual got the quicker 0-60 times due to the bogging down off the line on the autos. Yeah, that's what I'm getting at with the times. On the road it's very difficult to get a manufacturers time. Need a strip with good conditions IMO.

Well, would you agree that the UK spec and the Jspec have the same power output? And also assume that they both have the same 0-60? We know that toyota lied about the power output to keep them under the 280hp gentlemans agreement that the 280hp skylines also have I was a little bit out with the Manual VS Auto but Parkers is one of the places I saw 4.9... http://www.parkers.co.uk/cars/specs/Summary.aspx?model=900

They lied loads though. The power output... 280hp. The 0-60, a second less than the UK? They couldn't exactly say that the 0-60 was the same as the UK spec with 40odd less HP could they Never seen an N/A with 250 in my puff. You will be lucky to crack 230 without nos or a turbo. Where are you getting that from?

Bit of both really. Guys pushing their cars on the 1/4 mile can get under 5secs (ok barely but it has been done). Power isn't the restriction, even in stock form. Also, from magazine reviews on the Supra where they have timed it. I think in the US they got 5.1, in the UK they got 4.9 and on autotrader they had 4.8 and 5.1 (Manual/Auto). I never trust what the manufacturer says. Especially so when it comes to any of the Jspec figures, as we all know. You won't really get anything from BPU on an N/A. I think the car will breathe a little freer but it certainly won't get you 1 second on your time. You might get 0.1 or something like that. Some good rubber and lots of practice will get the best from the car. If you really want to concentrate on 0-60 and 1/4 mile times then NOS is your only real performance option on the N/A without going onto turbo's or spending SERIOUS cash.

Toyota told a LOT of lies didn't they

You searched here? Where did you search? If we deleted all the 0-60, top speed, previous car and youngest owner threads all we would be left with is tech, off topic and NWS. Stock TT around 5 seconds (4.8 I believe is the official time) Stock N/A around 6.5 seconds (I think 6.7 was the official time) You are going to be hard pushed to get those times though, it takes a lot of skill, the right tyres, the right suspension, the right roads and the right conditions. It all has to come together for you really.

It'll do better than that in the right hands.

Cheers mate, I think it was the HKS cams I read about.

Wheeling it out is the easy part, getting it down onto and up off of the skateboard is the tricky part

Nope, plain old roadtax.

I've got a set of these.. http://cgi.ebay.co.uk/HEIGHT-ADJUSTABLE-CAR-RAMPS-CAR-LIFTS-CJAUTOS-/330542859082?pt=UK_Lifting_Moving_Equipment&hash=item4cf5e3c34a They work a treat. I need to remove the bumper to get the supra on them though. Could extend the ramp fairly easily though I guess.

Just wondering really. I know that some cams require re-shimming when fitting, and I guess due to wear stock ones at times will too, anyone any idea if I'll need to re-shim 269 GSC cams? When checking them for the shim sizes, should I head towards the upper limit or the lower limit? I was thinking upper limit so that there is less chance of wear? Thanks

Why is he asking £400 for Tax?

Is that all? That's a LOT lighter than I thought. Pfft, easy Hodge left hand to hold, right hand to loosen.

Won't be easy from your back mate. Do you have a gearbox jack? Makes the job a lot easier. WIthout you're going to need a fairly large trolley jack and a spare pair of hands to work the jack while you balance the box on it.

Recieved today, arrived in it's own carpet and everything. As I said mate, Niz aint got nuffin' on you
