Just had a read of the Autospeed article from the current issue "R33 brain transplant".

Hopefully the owner of the car can comment on the article.

Knowling, mentioned the car was considerably quicker. Any figures?

How bad is the wheelspin?

How does the car feel, revving to 7500r.p.m?

Have you experienced other problems after the article was written?

Detonation problems?

Any plans for future mods? If so get them to do another article on the car.

just a bit of advice to ppl,i would recommend against putting any type of aftermarket efi computer on it other than japanese ones.The factory ecu can be sent over to japan and re mapped to produce staggering results.....this is true...i have seen it..i have done it.Just a bit of advice take it or not...

Why not? Do the Japs drink special joo-joo juice that makes them better tuners? I know at least 2 excellent efi tuners of Japanese imports, and I'm in the backwater town of Perth! There are more than capable tuners Australia wide.

And what the buggery is the point of sending an ecu off to be mapped when the afr of the actual engine can't be measured in real time? Makes it as useless as those plug'n'play replacement chip bollocks, doesn't it.

Don't forget that Australia is home to Haltech, Motec and Autronic - some of the biggest names in ECUs the world over.

The japanese companys like trust hks spend millions on development.They have off the shelf ecu's for a particular setup that works right out of the create,without blowing up engines and what not.Ofcourse they know there own computer systems better than us.And alsothe use of such aftermarket system dont allow alot of features that the fact ecu does......try getting an R34 GTRs drive system to run on a autronic......imposible.Also get these guys to tune the R34 computer....i dont think so.Japs build em they know how to mod em

ok take this into consideration......i got a supra for my friend and it had these mods....Trust T88 turbine kit,japanese aftermarket fuel pump+reg,sard injectors,2.0bar of turbo boost(although this was very dicey)It also had a host of aftermarket goodies in the shock department,brakes,gauges and all the rest of it.Now this thing ran on Pump gas and guess what type of ecu it had?????

Factory one rewritten by C.O.C.Kpit.Now when people seen this car perform on the dyno at autosalon,they couldnt beleive it had the factory ecu.Now the car produced 386RWKW at 22psi.The car has 90,000klms and its driven EVERYDAY.Now...the car is still performing strong,although another engine is being built for more power.....so if you know a tune shop that will tune the FACTORY ecu,i will challenge them to do it without ****ting the new engine...and the engine will have noshortcuts so it wont be because of faulty asembly componants.Whats there number?

Went into the for sale section. A few people are selling remapped r32 ecu's for r33's. Why don't they remap the r33 ecu for an r33?

So lets take the challenge, give the number of tuning shops that can remap factory ecu's better than the japaneese. Remaping the standard one, sounds a lot better than going for an aftermarket system.

With the R33 ECU's the chip is read only - can't be re-mapped.

BUT - you can (and they do) install daughterboards with a seperate EPROM that can be tuned.

Personnally I wouldn't bother about sending a ECU to Japan to get retuned.

One thing to remeber - how would HKS in Japan know if your injectors can only run at 80% safely? Do the places in Japan know that our 98RON fuels tend to differ slightly, which could be the difference between detonation or not? Do the places in Japan know what the climate is in Canberra, or in Darwin? There's a big temp difference there !!!

And I'm sure that would effect the tuning.

I've been with Hitman the famous Haltec tuner, while he has tuned a car. And he has done a amazing job. BTW: The Hitman does work all around the world - so why send something O/S when it can be done a few hours away?

There is one bloke on the performance forums that has found a good tuner in Sydney(?) that can tune daughterboards for the R33 computer, basically you just need a ROMReader.

Just my 2c.

Personally, I'd never reconmend off the shelf tuning fixes to anyone. Well, not to friends anway.

Well, no. It wouldn't I suppose. Although any tuner with half a clue would leave the factory ecu in place to do its job and wire up the aftermarket ecu to soley take care of fuel and ignition timing.

All this doesn't matter though, I don't want to promote aftermarket ecus. I think what you intended to say in you first post is that factory ecus are more than capable if they are suitably tuned. If this is so, I wholey agree. As revealed to me recently (by rev210), factory maps have had a huge number of hours spent on them spent perfecting low rpm drivability, and thats the sort of thing that just can't be replicated privately.

I can't help you find a jza80 tuner (this is a skyline forum, afterall), but I do know the 2JZ factory ecu can be mapped outside of Japan. A quick Google revealed http://jcp.excitewebpages.com/main.php3?pr...primNavIndex=0& who sell daughter boards for jza80's. They don't specify on the web page, but I assume they can custom tune for each car.

What I'm trying to say is, tuning jap cars can be done properly outside of Japan and comments like "i wouldnt trust anyone in aust to do it" just aren't fashionable any more.

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
