R34 GTT Battery Relocation To Trunk

Hi all!

Looking to relocate the battery to the trunk of an R34 GTT.

I want to do it using as many stock GTR components as I can (including the harness protectors from the 34 GTR that run underneath along the chassis to the engine bay). So far I’ve purchased the battery tray from a 33 GTR, as the captive weld nuts are already there just asking to be used.

There is also the slight issue of now having to relocate the ABS/TC/Fuel Pump Control ECU, which in GTT’s sits right above where the battery will then sit on the tray.

Has anyone already achieved this, and if you have any pics that you wouldn’t mind sharing? It would be great to see how others have done it and where you put them, as there are countless holes in the parcel shelf panel to potentially use.

Just trying to get some ideas bounced around, and to help uncover any potential problems I may encounter by  my choice of location.

TIA for any help!

I believe there was a similar one posted by @duggyphresh.

They were re-routing their battery positive cable in the way I am also trying to achieve.

Sorry, I’m new to this forum, so was a bit late to the party by a few months and so reignited the old thread, as I wanted to know how they got on with doing it.

I did this mod in 2019 

You just have to modify the top bracket of the ABS/TC/Fuel Pump Control ECU so it sits more upright and closer to the back seat and run a good quality positive battery lead from the engine bay, the negative lead i just bolted down to the body in the boot.

I just got this system but haven’t installed yet

I got a Moroso sealed box (defect reasons) which will be set up same as their pic

The quality is high grade, the correspondence I had with the owner (former head designer for Rockford Fosgate) was unbelievable, guiding me with what I needed. Even told me not to buy some things as it could be sorted in a different way at his loss.

Just a bit of a bite with the exchange rate and don’t purchase gear in 1 hit that goes over $1,000 au, lol I forgot!

Hey mate.

I've had this on my list of things to do for a while, but got stumped by the bracket / ECU situation and haven't had time to look at it properly.  Would love to see photos of what you achieved to give a better guideline on how to approach this.

      You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.

      R32 gtr transmission strength, billet plate

      By cosline · Posted

      Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik

      Spotted on the street....

      By Rezz · Posted

      Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
