Hey all, A mate of mine is racing a hilux ute with a 1UZ and wants to experiment with the intake runners. Anyone got one that they dont want anymore? would prefer pickup in Sydney, if not, will pay for postage in Aus. Cheers, Riv.

We took the 3,500km trek from Sydney to Alice Springs in the centre of Aus to do The Finke Desert race... Needless to say a biiig couple of weeks. My apologies to my american friends who might miss some of the aussie references. When we left the car had been dynoed, but not tested. So we...

Hey all, approx how much is the difference between flywheel and rwhp on dyno? Would 20% loss be about right for a manual, 25 to 30 for an auto?

Hey all, The oil pressure weve been seeing is 50psi at idle cold, 25psi warm. Under revs this increases to 50. I figured this is ok, other 1UZ's ive seen are the same. Yesterday though I ran the oil breather lines out ofthe rocker covers to an oil catch can and under revs its now pushing...

We dropped our car on the dyno yesterday for a tune... long day, a few hiccups but a good result. prob 1: Powersteer feed line (we've buggered off the bottle) wasnt feeding enough fluid to the pump due to a 90deg forged bend. whoops. Trips to various places to get the hose and and as a...

Hey all, Just after some suggestions ideas for future engine upgrades. Currently the engine is stock with twin TB and extractors, 1.5" primaries into 3" with crossover and a pair of 5" supertrapps. Its running a Haltech ECU and will be on the dyno soon. I need torque from the 1uz, not HP...

Hey all, Just thought I'd share some info on powersteer mods that ive just had done. Had a pump which needed a rebuild so sent it up to brissy (ultimate power steering) to have it rebuilt and modified. We didnt want more pressure, but did want to increase flow as we're running a 2" ram...

Hey all, In the future I'll be upgrading the ignition system and moving away from the dizzys. We're running a haltech E11v2 which only has 6 ign outputs so it has to be wasted spark. Im looking at 3 different options and would welcome any comments: Option 1 - Dual coils: 4 x dual coils...

Hey all, OK, Im armed with a multimeter and want to test that all leads are OK. I assume Im testing for resistance - what should I be looking for? Any help appreciated! Riv.

Hey all, plenty of info in here for FI 1UZs, what about stock? What plugs would you suggest? Especially for startup and dyno? Redline will be 6750. Whats the standard plug gap? I was shooting for .040", sound ok? Cheers, Riv.

Hey all! Been a while since I floated about in lextreme. Will have to update the details of the car I guess! Im after a set of new injector plugs (preferably not top $$ from toyota!) as some of mine are busted due to them being too brittle. Im also after a TPS (spare to mount on my twin TB...

Hey all, Anyone got preferences on flywheel weight? Whats stock? Whats a good weight for an offroad racecar that needs tq more than hp, but still needs good throttle response?

Hey all, Im not getting enough push from my stock pump for the ram - Its a Howe truggy rack with a 2" piston so Im not surprised the stocky is struggling! I know theres supposed to be a way to increase pressure or flow - anyone know anything about it? Any help appreciated!

Hey all, Anyone got a power steer pump they're not using or may be hoarding? The one on the racecar doesnt sound healthy at all!!! I dare suggest its about to have a coronary. Prefer pickup in Sydney, but will pay for postage from anywhere!

Hey all, Ive setup my thermo's to run at between 80 and 85 DegC. Not having actually driven it yet Im not sure if its gonna stay at this temp or not, but one thermo from our twin setup keeps it quite happy between 80 and 85. question is, is this the correct temp range for a 1uz? Or more...

Hey all, Our car is still on the "just get me fired" tune which means its running stupendously rich. Fire it up and you get fluid out the exhaust, lots of black smoke and eyes watering so much you could solve the aussie water crisis... So we fired the car, testing bits and peices a few...

Hey all, Im running the stock pump, modified for a much larger, baffled resevoir. Does anyone know what PSI and flow rates they run at? Also, is there a recommeded grade oil? or off the shelf whatever is fine for sustained revs? My system is: stock pump (may go for smaller pulley to...

Yes its true, Im a wanker. (and thats aside from the fact that I masturbate!) Had a couple of probs firing the car. Firstly was mis-wiring the sensors using trig and +, sync and + instead of -, plus having some shielding issues. SOrted that pretty quickly when a mate pointed out that its A)...

hey all, we went to fire the racecar for the first time on the weekend, and aside from a few wiring issues we couldnt actually start the engine as winding it over we had zero oil pressure. I'll be pulling the engine out tonight and pullng the sump to make sure that Ive not done anything...
