Gt35r Vs Garrett T04z - Discussion (just Post In This Thread To Create A Database)


Recommended Posts

haha thought that might stir you up...

mine went 574 @ 24psi thank you very much!!!

plus it also went 560rwhp at 20psi but yoda backed off timing so it was nice and safe :)

brockas should make anywhere between 560-600rwhp i would imagine, hopefully 573.9 so I can give him shit for years to come :banana:

i know you were stirring, i dont think ive seen a non-stirring post from you yet. :)

Yer i agree on brockas figures, he has pretty big cams so that should help alot, i think he has no port work on the head at all from memory? im thinking 575hp on the roller and 625hp or so on the hubber.

Im keen on those precision turbos mentioned, they seem pretty good from what ive read up but cant find prices anywhere and any real solid info on them, like are they watercooled and ballbearing, t4 flanged, twin scroll?

270 it is then. .1L shouldnt make a huge difference anyways.

It's not even 0.1L

RB26 isn't a true 2600cc. It is less.

IIRC its about 70cc difference RB25 to RB26

Have any of you guys running rb26's in your gtr with either to4z or GT35r got upgraded valves/springs etc in your top end or what have you had to do besides cams in the top end?

just wondering how a stock head will go on a built bottom end with say a GT35R? interested in this thread, coz im tossing up which way to go down the track a bit.

You can get the Billet Turbos in Journal or Ball Bearing. Wide variety of T3 and T4 exhaust housings are available. There are different compressor housing options as well. About 1000$ for the Journal version and 1400$ for the Ball Bearing version i think. Contact a turbo destributor and ask about the Precision Billet 6765. There are a couple being sold on ebay as well.

Stock head, with the only work done for clearance of the 10.8mm cams, and upgraded springs.

Valves are standard.

ok. thanks, interesting to know what others have done etc for there set ups, gives others a chance to compare and see where the best place to spend your cash is in an engine build up process.

^ plenty of guys running @ 380-400rwkw, factory valves/cams and bit of a tidy up.

More depends on the condition of the head to begin with really, one person might be fine, you might not and vice versa

yeah totally agree. i would get the head fully rebuilt when it goes back on once i do the engine, just to make sure everything is going to run smoothly.

also what manifolds are people running? has this has much of an affect also? in the future im looking at maybe a GT35R on highmount manifold (most likely 6boost) just slowly planning it all first and what parts i need to aquire.

Car run in..

Getting tuned end of this week/ next week ...

Will post results..

Built 26... garrett .84 t04z

Been a long wait... good luck!

I'm about to bolt on a T04Z with .81 rear housing, so we will have a direct comparison, on the same dyno with the same engine, between a GT35R and T04Z.

Should be finished by next week.

any results on this?

Was just about to post here.

No results just yet.

As it needs a complete retune anyway, we've taken the opportunity to install a Power FC d-jetro, and get rid of the AFM's.

Unfortunately, this makes it no longer a 'bolt off bolt on' situation, but the lack of AFM's shouldn't really effect top end much, just driveability.

Power FC arrives next week, hopefully tuned on Thursday/Friday.

has anyone had both these set-ups on a car before or seen them on cars. im looking at the exact same problem.. cant choose which one

    • 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. 
    • 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.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 馃槀 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • 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
    • 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.
