Hi I have been looking at upgrading my turbo with something that will just bolt straight on. I am looking for around 260rwkw. But I want to keep the lag right down to a minimum I have been looking at a Trust TD05 18g. I just want to no if anyone else has used these turbos before or no of anyone who has and what results they have had.

My car is a R34 skyline

thanx

No way on earth it will make 260rwkws. It should be responsive though as its a pretty small turbo.

This is a guess, but std EVOs use to come with turbos from the TD05 series... for that power a TD06-20G is more the go, though im yet to see a T3 flanged internal gate one make that sort of power.

General consensus is a 2535 or a GT-RS is the better avenue to pursue, or try reading bullant_47s thread in forced induciton on the GCG Hi-Flow with VG30 rear housing

Evo Turbo's up to EVO III are TD05 16G.

the newer EVO's have been using something else.

I had a 16G on my VR4.

it was pretty responsive on the 2L.. I'd say 1bar boost by 3500rpm in somparison to the stock turbo (which is a td05 14B) makes 1Bar by 2900 I think

TD05 on an RB20 sounds like a winner.

TD06-20G is pretty good balance between response, a reasonable power figure at sane boost, and the good old turbo kick/feel....on an RB20 that is.

Even on an RB25 where it should be able to punch out 260-270rwkws, i would be surprised if on an RB25 a GT-Rs or GCG Hi FLow could match it for response and power...

^^^^^^^

So it I able to make the sort of power that I am after then.

how responsive was it?

Was it nice to drive?

I just want it for drifting so i want minimum lag that is why I was going for the smaller turbo over the bigger.

I have a mate that has a TD06 25g and it is to lagy for what I would like. I have been also told that their I a guy over in Victoria with a GTT with the same set up as mine and he is producing 270rwkw on 1.2bar.

Here's the Boost Graph - It made 1.2bar by 3200rpm and held that til 5000rpm before slowly dropping back and holding 1.0bar by 6350rpm til 7250rpm

Ignore the spiral effect - the operator over-boosted it at 1st

That was with a completely standard head/cams etc just lots of bolt on bits. I was aiming for Tomei 260' Cams and Pulleys for even more poke.

It was fantastic to drive - good off boost preformance too.

      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.
