performance upgrade questions

Hi guys,

I'm in the middle of deciding how to upgrade my gtst's performance, and number of options have come up over the last few months...currently i am chasing a fmic before anything else happens, but after that, i dunno wut i could do to the car and would like a few ideas.

right now the car has a hi-flowed T03/T04 hybrid turbo, complete turbo back exhaust, pod filter, stock cooler, S-AFC, EVC 3 boost controller.

It managed to make 200rwkw at 15psi of boost after tuning the S-AFC (comes to abt 270rwhp).

Could anyone gimme an idea of wut sort of power this car could make once a fmic is installed? The car would probably be running at 10psi most of the time, or maybe even stock...I just want to know wut sorta power I would be making. If it feels sufficient, I may call it quits as far as performance goes, and concentrate on the suspension and brakes like a good boy.

Hypothetically, a budget of around 4k-5k would be do-able after the fmic is installed...would take a while, but do-able...would like to know wut could be done with this money.

I have more in-depth questions, but will post them once opinions have been made regarding these questions first.

Please feel free to talk at length, then everyone can benefit from the know-how

thanks,

Zak

Hi Nrage33, I would suggest a GTR fuel pump as the next mod as you are getting close to the limit of the GTST fuel pump. Then a standard R32/33 GTR intercooler (good up to 300 rwkw) usually gives a 20 rwkw increase over a standard R32/33 GTST intercooler. I would then suggest an adjustable exhaust camshaft pulley. That should give you 230 to 240 rwkw which is pretty close to what the standard internals will handle.

Hope that helps

sydneykid,

thanks for the info...what does an adjustable exhaust camshaft pulley do anyway?

I'll definitely look into the fuel pump tho, I can feel these current fuel pumps I have are near their end...

If i wanted to reinforce the internals, what exactly would I need to do?

2.5 lit should be fine depends on how much power you are after..and if you are going over 240rwkw then probably some mild internal work...but after that you can push it even more depeneds on how much money it comes too in the end...remember tuning and dyno time as an extra cost..

This is what happens when you are making 240rwkw with an RB25 and then slap a RB30E bottom end in there.

Due to the head flow charastics the final power is still roughly the same.

I guess the saying still applies.

There's no replacement for displacement. :burnout:

      Tein Circuit Master- rebuild worth it?

      By MBS206 · Posted

      If they can dyno them, get them dyno'd, make sure they're not leaking, and if they look okay on the dyno and are performing relatively well, put them in the car.   If they're leaking oil etc, and you feel so inclined, open them up yourself and see what you can do to fix it. The main thing you're trying to do is replace the parts that perish, like seals. You're not attempting to change the valving. You might even be able to find somewhere that has the Tein parts/rebuild kit if you dig hard.

      Best place to order Authetic R32 Parts in Japan

      Can you also make sure the invoices on the box (And none exist in the boxes) are below our import duty limits... I jest, there's nothing I need to actually purchase and order in. (Unless you can find me a rear diff carrier, brand new, for stupidly cheap, that is for a Toyota Landcruiser, HZJ105R GXL, 2000 year model...)

      Murphy strikes again! Nothing at all would have gone wrong if you had the tool kit in the car! You'd have just found the clamp loose the next time you went to touch it...

      Blue slip

      By MBS206 · Posted

      I have been being VERY quiet about what you're alluding to, as it is something that ticks me off... The number of cars from factory that run coil overs is HUGE! Most of them these days do... The other part that annoys me, is people saying "Well all the incabin adjustable suspension is illegal by blah blah blah"... If that's the case, then why can I buy a car brand new that can do it if, FULL STOP in cabin adjustable suspension is illegal...   Also, I could just chuck some aftermarket shocks in my car, throw the stock springs on, after my blue slip, dump my super low springs back in. Same shock and spring style setup... Hell, they could also be the same colour springs etc.     I'm voting, BlueSlipper didn't want to touch the above car for some reason. Whether it be some sort of bias against the car, the owner, them maybe having previously done dodgy shit and now they're being super careful in case they get slapped in the face by the Gumbyment again... Find a new blueslip place.   And can confirm as you had said, yes there are holy bibles of vehicle heights, and all sorts of other suspension stuff. Heck your run of the mill mechanic, and tyre shop has access to all of that stuff. It's how they do wheel alignments...

      Funny story Heading to Sydney this morning on the HWY there was some slow traffic, so I gave it the beans and midway through my overtaking "power run" I lost all power It seems that I missed a hose clamp,  and the MAF and filter went WiFi To make this more problematic, the little tool kit that lives in the boot, is sitting in the sun room at Goulburn......LOL Luckily for me I found a bit of steel on the side of the road that could be used like a rusty and bent flat head screw driver to tighten it up enough that it got me into Sydney, it is now all tight like a tiger with the aid of a 8mm socket Note to self: Use my brain and double check stuff, and always keep that little tool kit in the car for when I have a brain fart
