steel wheel upgrade or garret -7s

hey guys, new here. want to upgrade my turbo chargers so I can safely run 1bar or a bit more boost. not after crazy hp as its just street driven but may want a bit more later. would guess its at 300 now with tomei cams, cam gears and mines computer and straight through exhaust with 1 rear muffler. currently on 10-11psi.

 

I can get steel wheel stock turbos for reasonably cheap, they are always on sale here or I can get mine rebuilt for not a lot. otherwise its the garret -7 option (which seems to be perfect for what I want which is response) but I would just be putting those turbos in, probably dumps and run 1-1.2bar.

 

which option would be better? obviously I would like to go the cheaper as garrets are double the price of steel wheel upgrades. if I can get 400hp I would be stoked. don't want to have to uprate to much else.

 

I have a pretty large budget but am saving for a property purchase so don't want to throw 10k at this if I can help it.

 

its for a rb26.

Factory turbos with steel wheels put in them never perform as well as the bolt on garretts do. 

Instead of the -7s look into the -9s they give the same response (maybe even slightly better) but flow slightly more power

would I need any supporting mods to run the power level I am after? 400hp is my goal as its just my weekend car and I like my license also. not a racecar.

If I can buy turbos and some second hand dumps and put them on for 3kish that isn't too bad.

I know the garrets are better but I don't want to go overkill if I can do it for half the price. I find the car fast enough as it is for the street but I just want a bit more.

It's the response difference as well that make the garretts better and in the long run the price isn't much different.

 for 300kw (400hp) you'll need a set of injectors and a fuel pump unless it's already been changed and a clutch that will be up to the task as well, plus the usual exhaust and etc

To put things into perspective, my V-Spec II made 325kw at 20PSI boost at the RW's with the following mods:

  • Nistune ECU Upgrade
  • NISMO AFS
  • HKS EVC 6 Boost Controller.
  • Sard 720cc Injectors
  • Walbro Fuel Pump Upgrade but size not known
  • Garrett GT2859-9 Turbos
  • Tomei Adjustable Cam Gears (Intake and exhaust).
  • HPI 3.25" Dump Pipes
  • High Flow 3" Catalytic Converter
  • 3.25" HKS Exhaust System with 4.75" Cannon.

Cheers,

Bob.

already have an upgraded fuel pump. also full straight through exhaust from dumps back, so no cat and just a straight through muffler at the rear so should flow well. 3.5 inch.

 

wouldn't different injectors then require aftermarket ecu? can I not get 400hp on the stock injectors? I thought they would be fine and I would have expected the clutch to be fine also. im not planning on launching it everywhere, just some 2nd or 3rd gear squirts up to the speed limit

Thanks mate. Was on the work computer so alot of stuff doesn't work, just jumped on my phone but you beat me to it.

might keep an eye out for a good deal on a second hand setup. Otherwise just bend over, pull some cash out and get it all done properly.

Standard injectors run out of flow at around 350hp and an aftermarket ecu would be required even to reach that. 

Lesson that needs to learnt before even touching a bolt on these cars, nothing is cheap and if you want to play you need to pay

yea mate ain't that the truth.

 

already looks good, just everyone expects it be some insanely fast weapon. which currently, it isn't. its fast, but not fast fast.

Yeah I know how that feels, had mine since 2003 and it made 240kw until last year when I finally decided to pay to play with it

Thinking she may keep her standard turbos for a while but who knows, might start a car only fund so it doesn't look like im blowing too much on it.

 

Bob that Vspec 32 looks ace mate. Nice and clean. Don't see many silver GTRs over here.

      High temp brake fluid?

      By Murray_Calavera · Posted

      I've always approached this as, price is comparable between low temp and high temp fluid. Just put in the high temp fluid. I've not going to lose any sleep thinking about could I have saved $20 on brake fluid that is going to live in the car over the next 2 to 3 years.

      Nah, the creases were pretty large, and the sheet metal is pretty thin and hard to work out, time alone is in the hours to fix, and would probably have more bog than I would be happy with In other, more happy news, I gave MX5 Mania a call and they have a few clean boots available for $400 a peice, I've contacted Fineline and given them their contact details, I'm a idiot for not thinking of them sooner

      High temp brake fluid?

      By GTSBoy · Posted

      That really depends on how hot the brakes get and how much of any heat is transferred into the fluid. That really makes it at least a vehicle specific question, and more than like a specific vehicle specific question, depending on what brakes (ie stock, bigger rotors, different calipers) or even what pads are on it. And then there's the question of cooling air. Is there plenty stock? Is there no special cooling arrangements stock? Has some/more been added? In other words, I think you have to do the experiment to obtain the data. And if you;re worried - tie on some ducting?

      High temp brake fluid?

      By PranK · Posted

      In all the track days I've done over the past few months I've only had 1 issue with braking and thats with my current EBC pads (can't remember the colour, but they're not a track pad). I don't *think* I have had issues with brake fluid getting too hot, my understanding is that when that happens you will have quite noticeable brake loss - which I haven't had.  I'm using just regular ol' Penrite Super DOT4 fluid. I use this fluid in everything and my cars always seem to stop so I see no reason to change, except ... for the 335i. I need to do a fluid flush and was thinking about my fluid of choice and wondering if I should consider using something more high temp? Its not a super fast car by any standards but I'd hate to do a flush and then find myself with no brakes when I get. to Wakefield.  I guess, my question can be summed up as "How fast do you need to be driving to need higher temp brake fluid?"  I remember high temp fluid was considered a must have back in the day when I had my GTR.

      RB25DET in GTS4 R32 conversion

      By Jason Abell · Posted

      For anyone that comes here looking for answers on what can go wrong with gts-4 to rb25detneo swap. The Gloria's awd sump is different and does not fit. The rb25neo from stagea are exactly the same sump bolt pattern and axel alignment. Castings numbers are different on Gloria's blocks and oilpans if they need to be identified.
