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.

      Thanks for that, I'll check it all out. I can always do the brakes last anyway if its a problem.  The 16's are super cool, if they do fit I'll cruise around with them for a bit.

      Well, that's kinda the point. The calipers might interfere with the inside of the barrels 16" rims are only about 14" inside the barrels, which is ~350mm, and 334mm rotors only leave about 8mm outboard for the caliper before you get to 350, And.... that;s not gunna be enough. If the rims have a larger ID than that, you might sneak it in. I'd be putting a measuring stick inside the wheel and eyeballing the extra required for the caliper outboard of the rotor before committing to bolting it all on.

      OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup

      Well, apparently they do fit, however this wont be a problem if not because the car will be stationary while i do the suspension work. I was just going to use the 16's to roll the old girl around if I needed to. I just need to get the E90 back on the road first. Yes! I'm a believer! 🙌 So, I contacted them because the site kinda sucks and I was really confused about what I'd need. They put together a package for me and because I was spraying all the seat surfaces and not doing spot fixes I decided not to send them a headrest to colour match, I just used their colour on file (and it was spot on).  I got some heavy duty cleaner, 1L of colour, a small bottle of dye hardener and a small bottle of the dye top coat. I also got a spray gun as I needed a larger nozzle than the gun I had and it was only $40 extra. From memory the total was ~$450 ish. Its not cheap but the result is awesome. They did add repair bits and pieces to the quote originally and the cost came down significantly when I said I didn't need any repair products. I did it over a weekend. The only issues I had were my own; I forgot to mix the hardener into the dye two coats but I had enough dye for 2 more coats with the hardener. I also just used up all the dye because why not and i rushed the last coat which gave me some runs. Thankfully the runs are under the headrests. The gun pattern wasn't great, very round and would have been better if it was a line. It made it a little tricky to get consistent coverage and I think having done the extra coats probably helped conceal any coverage issues. I contacted them again a few months later so I could get our X5 done (who the f**k thought white leather was a good idea for a family car?!) and they said they had some training to do in Sydney and I could get a reduced rate on the leather fix in the X5 if I let them demo their product on our car. So I agreed. When I took Bec in the E39 to pick it up, I showed them the job I'd done in my car and they were all (students included) really impressed. Note that they said the runs I created could be fixed easily at the time with a brush or an air compressor gun. So, now with the two cars done I can absolutely recommend Colourlock.  I'll take pics of both interiors and create a new thread.
