Interesting read...

My main aim for the car is 90% road and 10% Drag strip (no drift or circut)

I have spoken to a few tuners and they all said "Nissan build the best 4cyl and Toyota build the best 6cyl"

Whether I get a GTR or a Supra im just going to do all the bolt on mods to geting going fast. I have seen some 2JZ's with the HKS T04Z and they are pumping 500+ rw/hp on stock internals! Now i have yet to hear of a stock RB26 with a T04Z even coming close to that... Have any of you?

That black Supra THNKB4 was tuned by Adam at J.E.M and i have seen this thing on the dyno and it is an animal

Yet another animal Supra:

Then again... this looks like sex on wheels too!

So damn hard to choose... i think the best way is to take my time... not to rush.. when I find that Supra/GTR that wins me over... ill just buy it!

Edited by QRI05E

ive said this a million times...

Both engines cost the same to get 500hp ffs

they both handle more than 500hp with stock internals so easily

never seen a T04z equipped gtr makin 500rwhp?? not even close?? dude.. im makin 410hp with a pair of hi flowed twins... no big deal. a T04z will make a shit load more then that.. even a GT35R equipped GTR makes more then that

In sayin that, so will a 2JZ. The 2JZ will also spool the turbo up quicker makin more torque sooner than the GTR, but it doesnt rev as high meanin once it comes into stride u havent got all that much time to play with it. 7000rpm limit compared to 8500 for a GTR or if ur game.. add another 500rpm to each.

To top it off the 2jz is also more reliable @ higher hp outputs. That is probably due to the 2jz being built slightly stronger, but it also doesnt rev as high or hard so it will naturally be more reliable.

Now the problem with a Rwd car that has massive midrange torque as well as a strong top end is that it only has 2 wheels to transfer all that extra torque and power = excessive wheel spin. Of course tyre selection can reduce this, But a GTR which will produce less torque down low doesnt have this problem.

Having a higher RPM limit also makes the power more usable in the sense that instead of having 500nm @ 2000rpm which isnt as comfy as u think, it makes the same 500nm but @ 4000rpm. Torque isnt delivered as brutal because 4000rpm might be 40km/h instead of 20km/h. To add to that is its 4wd system allowing the brutal transaction to be delivered just as brutally to 4 wheels using the same tyre selection.

BUT!!!!!!!!!! a 2JZ in a GTR using a 4WD system would be optimal.

Tell the oodles of people that have had their RB26's die in a nice fashion @ 500hp (or less) that you think its fine.

Im sure they will all believe you and it will make them feel 10 times better about thier rebuild

Reality is though, they dont last. The sooner you understand this the better off your posts will be for this forum.

So many people have lunched them for many varying reasons, stock part failures and so on where the 2JZ has far far less documented problems (read:basically none) at that level.

When he said close/t04z etc, he means in terms of not shitting itself at some point down the line, which just about every RB26 would making 500hp.

ummmmmmmm... ooookkkkkaayyyy :P .

have a look on supra forums mate. im sure they could shed some light on this issue

Don't seem to be very easy to go quick in on the drags without some tyre changing at the track?

At least these are what times the WA cars run. Decent, just not what I was expecting with all the hype?

http://www.supraforums.com.au/forum/showthread.php?t=40790

most supras are built over here for dyno comps, they can be set up to go quick on the quater easy, just need to look to the US for how to do it. that purple supra from millenium ran 10.0 with a 2.2 60ft, when that gets sorta its easily gonna run mid 9's, and i think hes on radials aswell, not slicks, could be wrong on that htough

Don't know how easy it is? Seems like it's not as easy as a gtr to run 11's at least?

The standard supra gearbox seems to have less strength than the gtr gearbox too.

Alot more to a car than just it's engine is the moral of the story I think.

i think i disagree with the box as well.. ive always known the 6 speeder to be as bullet proof as its engine.. '

If th engine was the decider on what was a better car, then the supra would win hands down. But like Rev210 said, theres alot more to a car than an engine..

because of this, the GTR always wins hands down.. just look @ its track record around the entire world :P

yeah only issues with supra gearboxes are the W58's (non turbo) when people turbo there car. the supra box is tougher than any skyline box (exclusing R35 obviouslym as its an unknown) bar the 34 GTR, because its the same box.

never heard of the GTR being king of the streets but yes brakes are better and 4wd obviously. supras are better value for money because they maintained the same design while the skyline spanned 3. that said a 2001-2002 manual RZ would be getting up there with cheap GTRs in terms of price, since GTRs have come down so much

    • Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s
    • It was picked up on the MOT/Inspection that the offside front wheel bearing had excessive play along with the ball joint. It made sense to do both sides so I sourced a pair of spare IS200 hubs to do the swap. Unfortunately I don't have any photos of the strip down but here's a quick run down. On the back of the hub is a large circular dust cover, using a flat head screw driver and a mallet I prised it off. Underneath will reveal a 32mm hub nut (impact gun recommended). With the hub nut removed the ABS ring can be removed (I ended up using a magnetic pick up tool to help). Next up is to remove the stub axle, this was a little trickier due to limited tools. I tried a 3 leg puller but the gap between the hub and stub axle wasn't enough for the legs to get in and under. Next option was a lump hammer and someone pulling the stub axle at the same time. After a few heavy hits it released. The lower bearing race had seized itself onto the stub axle, which was fine because I was replacing them anyway. With the upper bearing race removed and the grease cleaned off they looked like this The left one looked pristine inside but gave us the most trouble. The right one had some surface rust but came apart in a single hit, figure that out?! I got a local garage to press the new wheel bearings in, reassemble was the opposite and didn't take long at all. Removing the hub itself was simple. Starting with removing the brake caliper, 2x 14mm bolts for the caliper slider and 2x 19mm? for the carrier > hub bolts. I used a cable tie to secure the caliper to the upper arm so it was out of the way, there's a 10mm bolt securing the ABS sensor on. With the brake disc removed from the hub next are the three castle nuts for the upper and lower ball joints and track rod end. Two of these had their own R clip and one split pin. A few hits with the hammer and they're released (I left the castle nuts on by a couple of turns), the track rod ends gave me the most grief and I may have nipped the boots (oops). Fitting is the reversal and is very quick and easy to do. The lower ball joints are held onto the hub by 2x 17mm bolts. The castle nut did increase in socket size to 22mm from memory (this may vary from supplier) The two front tyres weren't in great condition, so I had those replaced with some budget tyres for the time being. I'll be replacing the wheels and tyres in the future, this was to get me on the road without the worry of the police hassling me.
    • Yep, the closest base tune available was for the GTT, I went with that and made all the logical changes I could find to convert it to Naturally Aspirated. It will rev fine in Neutral to redline but it will be cutting nearly 50% fuel the whole way.  If I let it tune the fuel map to start with that much less fuel it wont run right and has a hard time applying corrections.  These 50% cuts are with a fuel map already about half of what the GTT tune had.  I was having a whole lot of bogging when applying any throttle but seem to have fixed that for no load situations with very aggressive transient throttle settings. I made the corrections to my injectors with data I found for them online, FBCJC100 flowing 306cc.  I'll have to look to see if I can find the Cam section. I have the Bosch 4.9 from Haltech. My manifold pressure when watching it live is always in -5.9 psi/inHg
    • Hi My Tokico BM50 Brake master cylinder has a leak from the hole between the two outlets (M10x1) for brake pipes, I have attached a photo. Can anyone tell me what that hole is and what has failed to allow brake fluid to escape from it, I have looked on line and asked questions on UK forums but can not find the answer, if anyone can enlighten me I would be most grateful.
    • It will be a software setting. I don't believe many on here ever used AEM. And they're now a discontinued product,that's really hard to find any easy answers on. If it were Link or Haltech, someone would be able to just send you a ECU file though.
