Ran up my friends 1UZFE-TT on the same dyno as I did my forged RB26DETT.

He pulled an impressive 372KW ATW (I did 384kw) in his Toyota Hiace VAN with a stock bottom end (Has head work and turbo cams).

He had about an extra 100NM but only made 200kw 300RPM quicker than my car and I pull right up until 7800rpm his stops at 6500.

I thought comparing the two engines was going to be interesting and it was.

Impressive numbers from the stock bottom end....might be abit more in it with a new fuel pump.

Well, the stock ones have got about 3mm of lift and about 190 degrees of duration (jokes, but not far wrong!), so even an aftermarket cam is not likely to be too big. Basically, Toyota didn't need to put much cam in the engine at all to achieve the 206kW target, so they didn't.

Not sure what you guys are doing wrong but the old 1UZ is one tough engine ive spoken to plenty of people who would even say pound for pound its one of the best engines round. when visiting my bro in Sydney last we went out to the drags and saw a street car (yea yea registered but not practical to drive) pull a low 8 with a stock bottom end 1UZ

Anyway interesting result and in a Hiace van im sure its a handful

Cheers,

Something to do with the intended use perhaps? You can do insane things and swim against the current but eventually the roots of a motor can't be ignored IMO.

    • I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.
    • The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.
    • Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.
    • Since winter isn't that harsh anymore in Poland, i will definetely drive it 365 days a year 😉. But if the snow hits i will try it for sure and let U know. Only swap i am planning to do is of course R34 GTR front 😍.
    • Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
