R34 Build/diary

Why do you need a 100% effective heat exchanger? Your fuel doesn't need to be ambient air temperature, you just want to keep it reasonable. A cooler will do the job.

[B-rice]

Yh true didn't they were good enough to cool it to a decent level. I'm going to be looking into a few kits out there

[34GeeTeeTee]

How effective are the fuel coolers though,are they like intercoolers which are about 85-90% effective. I guess it also depends with where theyre mounted too.

Check my build thread for pics (probably back 10-15 pages) mine is setup like larger version of the Z-tune one (I think that's what Bobby said) but it's mounted under the spare wheel in a small diffuser type setup... Pretty sexy!

Finallly got to install my flex fuel sensor, its all hooked up and everything but i havent tuned the car for E85. So at the moment im just finishing off my fuel system. All i have to do is upgrade the old fuel lines so they wont corrode, when i do the full transition to E85. Currently my fuel temps are lingering around 20-36 degrees during light commute duties. Not sure if i wasted money with the fuel cooler. Its use might come into play during the summer season.

Managed to fab up a simple bracket to hold the flex fuel sensor next to the fuse.Had to remove the brake cylinder stopper as im still in the process of making spacers that will go inbetween the BCS and the brake for the sensor.

Nice work, I have the older style sensor hidden behind the BMC between it and the guard

[Hanaldo]

Nice job! Wish my engine bay had that much space

[B-rice]

I should be running outer space quite soon when I fit a new plenum, hopefully not too much.

Another update, got my wheels back from powdercoating. Gotta say they look brilliant.The best part is that I only spent $40 a wheel to get them painted.

[34GeeTeeTee]

Wow epic price and look awesome!

been trying to remove the turbo so that i can put on new gasket to stop the scream while on boost. The worst part about this is taking out the lower nuts. Its one b*tch of a job. Anyone have any ideas or techniques of how to remove it. Was thinking of grinding off a bit of the spanner for it to fit in. I would like to know how the japs fitted it in the factory because just putting on the cement on the leak was a challenging task

Also if i did remove the oil and water lines on the turbo. Does that mean that I have to bleed the coolant system again and probably do an oil change too. Im contemplating doing this, or trying to fit the gasket without removing the hard lines.

[Hanaldo]

It's easy enough to do with the right tools. But the bottom nuts are much easier to do from underneath.

As for removing the lines, yes you will have to bleed the coolant but you shouldn't need to do an oil change. But should be easy enough to change the gasket without removing the lines.

[B-rice]

Hanaldo always to the rescue, thanks.I managed to remove the bottom ones by going underneath. I noticed whoever owned it before didnt do them up properly, the metal tabs where the only thing holding them from getting undone

[Hanaldo]

No problem mate, I remember how frustrating a job it was the first time I did it. It does get easier! I can have the whole hot side off in about an hour these days haha.

Was the metal tab on properly? They are prone to undoing themselves over time, so they may have been done up but just loosened up a bit.

Hey mate

nice car, I also am from Canberra and own a silver R34 GT-T on E85. Where did you get your rims powder coated?

Also who are you going to get to tune your car for flex fuel?

[B-rice]

Hey man, I got them done by mobile fabrications. If you can sand blast them yourself it will be $40 per wheel but they can do the blasting plus painting for $88. From the results they did on mine i think they know their shit. They even had experience with forged wheels because you could wreck them if overheated.

Im getting my Tune done by Autotech. But have also been considering taking it to ultimate tunes. ESP said Vipecs cannot do flex tune (it was a diplomatic way off saying he cant do it). Im learning towards Autotech because he has some extensive experience with Skylines. Depends what you have also and the quality of work your after.

[iruvyouskyrine]

For next time you replace the turbo. Make life very easy.

[B-rice]

Lol. I started the car 40mins ago to set the gasket sealant and voila you come up with an idea i never thought of. My next turbo change will be a topmount if the permalock i put on these doesn't come out ill just rip it all out with the manifold hehe.

Ah sweet mate, yeah the rims look great.

I would be interested to see what you reckon of how it runs on the flex fuel and how difficult/expensive it is to tune. Do they have to tune for 98 and E85 and then several points in between? I was not aware of tuners in Canberra that had extensive previous experience in tuning flex fuel and had not heard of anyone else from Canberra getting their skyline tuned for flex fuel. Based on that and the fact that I already had my power fc on the car, mine just runs a power fc and caltex E flex all the time. It has been that way for 6 months at 320 rwkw and I am pretty happy, but it just means if I ever want to go to wakefield or something I would have to load the car up with Jerry cans so I would have fuel to get home. So on my next round of mods I may change the ECU. So let us know how you go

[B-rice]

Ed said he would tune E10,E20,30...up to E90 and 98.

Should be taking it for a tune in the next coming weeks. Just have to install the injectors but im still waiting on a rail that will fit 14mm injectors and also fit under the stock plenum. So far Plazmaman fuel rail seems like it has a chance of fitting under there. Also have to find out the correct diameter o-rings for the injector on the intake manifold. Will update you.

[34GeeTeeTee]

Good stuff! All happening

[Manuel Kasko]

Never saw this build thread!

Loved the read and those rims look shmick!

Good luck with the tune

Can't wait to see the figure it puts out
