the 3.0L twin turbo 2JZGTE motor is possibly the best engineered inline six built to date that is affordable. It has probably the best power to capacity ratio of any of the six cylinders available today, and are also a damn reliable bit of gear.

there is also a lot of jap aftermarket support for them too (which is not necessarily a good thing considering not all the jap spank makes things go faster).

All the RB26 fans will be in here in 1/4 of a second to defend the nissan stuff, so it boils down to you researching all the options yourself and deciding what is the best for you. an RB will always be an easier conversion into a skyline for example, but last time I priced an RB26 GTR motor it was twice the price of a 2J. :)

I own a mkiv TT and a 32 GTR and I can tell you from experience that the Supra engine wins hands down. Torque from the 2JZ is enormous from 2,000rpm and pulls like a freight engine to 6,000rpm. It flats out after that. The stock RB26 doesn't pull untill well past 3,500rpm and my modded one doesn't move until after 5,500 rpm. As a daily street machine, a BPU++ Supra eats anything in its path.

Then you lose the 4wd. Believe it or not, one of the Japanese tuning house has stuck a RB26 under a Supra hood and is racing the mutant with some success.

To give credit where credit is due, its relatively easy to spin the RB26 past 9k but doing even just 8k with a Supra will be much harder because of its long stroke design. The 6 speed has also got much shorter ratios meaning that if you're racing a GTR from a rolling start, when you shift from 2nd to 3rd, the guy next to you is right smack in the power band pulling a car length or two on you before your 3rd shift is complete. That's assuming both cars have similar power of course.

out of curiosity...my mate has a supra rz engine (i think its called), standard non-turbo supra. can he or is it possible for him to put a turbo in? i mean i know its possible but he seems to think that all he has to do is get the turbo and put it in (and only spend money on the turbo and installation-a couple of grand he rekons.). i thought that u would need a 2jz engine to cater for the turbo, or different wiring and along with the other shit to get it from a non-turbo to turbo.

Apart from different ECU, wiring, and different compression ratios you also can't just bolt the turbo manifolds to the NA block but I can't remember exactly what's the technical reason. The block is also different as there are oil squirters in the turbo models to cool the underside of the pistons. The NA block don't have this feature.

Ask your friend to check out www.mkiv.com. There's loads of info on mkiv and conversions. "Easiest" (and that's a relative term) way is to put in a 2JZGTE with harness, computer and the 6 speed but the conversion cost is not cheap. Economically, it might be cheaper for your friend to sell his NA and buy a turbo. Also check out the SX Engineering's website. I think they are developing a turbo kit specifically for NA Supras. Hope that helps.

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
