Hi I was wondering if low 12 sec qtr mile passes are possible with the stock turbos that come on the rb25's?

What are the best times you guys have got using the stock turbos and what other mods?

i think i high 12's 1/4mile is achieveable if you can drive...

i was running 13.8 @ 106mph with not alot of power.

on that night a wrx with the same mph, was running 13.1 and i know of a soarer that has run 12.9 with 108mph...

so if you can get your car off the line and have good gear changes, a high 12 is do able :O

good luck :spank:

Its definately possible but has to be a perfect run. I ran many low 13's, 13.0,13.1 and then 12.98@107. That was with street tyres and even a SAFC and no PFC.

hi can you tell me all the mods you had when you did the 12 and the boost

  • 4 months later...

Would an R34 GTT with the following mods -

Split dump / front pipe

Metal high flow cat

3" cat back exhaust

Apexi filter

and running stock turbo at 11 to 12psi

Decent 225 street tyres

- and some good driving be able to get a 13.0 sec pass? Also would getting a GReddy E-Manage Ulimate and a good tune with the mods above push the car into the high 12's??

Ta ;)

There is no reason you cant get 13.0 or close to it.

It comes down to driver skill/car setup.

More runs you have, more expirience you'll get.

Although 225's are a little skinny, but its just practice

You didnt have 208rwkw ;) Not with 103mph at least anyhow.

With 220rwkw i was doing 109mph 12.9 (not stock turbo) with 2.2 60ft's.

Your 60ft isnt too bad for street tyres, maybe you missed a gear or something? If you didnt... then the car just doesnt have the power the dyno reads IMO.

13.5 is still a good effort though with 103mph for whatever power the car has

R33 RB25DET standard turbo running 10 PSI full 3 inch exhaust, pod filter, just jap front mount, running on 19/30/265 Nankangs atleast 50% worn (on the inside anyways)

13.648 @ 165.14 K/mh roughly 102MPH

    • If you've only done the upper control arms on the rear, AND you have changed their length (by more than about 1mm) to set the camber you want, then you will definitely need/want to install traction arms also. Adjusting the camber arms on their own WILL introduce bump steer and make the car unpleasant to drive. Most owners have no idea that their car could behave infinitely better than what they put up with. I'm not entirely sure what the Stageas need, but I am thinking that unless you have massive front spring rates and pretty soft rear springs, you have waaaay too much rear bar. Oversteer city, in my estimation. Combined with possible excessive bump steer from maladjusted arms, that could be a recipe for nastiness. ATR43SS2 is not a highflow. It is an outright replacement turbo. It's a little bit bigger than the largest highflow profile that Tao does. Probably a solid 300rwkW turbo where the bigger highflows will be about 30-40rwkW less. Nevertheless, we're only talking about ~300 rwkW, which is well within the abilities of the stock ECu to run with a Nistune on board. I would do so without hesitation - and I will be doing so when I get my finger out and actually get the injectors and AFM installed. But, if you would prefer to drop a whole lot more money on the ECU side, then I suspect you're looking at Haltech. The Haltech fanbois here will all spout on about all the available engine protection you can have, that you can't have with the Nistune option. And they're right. But it doesn't really come for free either. You will spend more money on extra sensors and the like, plus the work to install them. If the engine was built and therefore represented a big investment to protect, then I'd say definitely do it. If you view the current (and forever into the future) shortage of replacement engines as something to prompt similar protection, then also, do it. If you see a destroyed RB25 as an opportunity to put in a Mercedes or other V12 (like I kinda do)... then your perception of the risk/reward might differ. These are good injectors. You can also get a "better" set of the same with more flow matching, for more $$. 1000cc is where you will want to be. You will need an R35 AFM and adapter tube if you want to stay with Nistuned stock ECU. Otherwise, if going Haltech, you can ignore. As for intercooler. Just about anything will do. You're only talking about ~300rwkW. Just put a big core in there. Be aware that return flows do add significant pressure drop and will cost power and will make the turbo work harder to achieve the same goals. If you can manage a proper crossflow, do it. I'm keeping my very good return flow because I'm only expecting to be in the ~250rwkW range, and will live with whatever outcome I get.
    • I have a heap that i have collected if you want some authentic ones still. Pm me if your interested!
    • Hey lads, reviving an old thread.  As an update, since the last time replied to this thread, ive done mostly suspension. Havent touched the motor except for maintenance. Though upon changing spark plugs, found out i had splitfires pre-installed! Updates: - Got me some stock airbox top cover and snorkel to fit onto the original intake. Should be free of defects - Bought a set of R34 GT-T brakes (not installed yet, going to rebuild + respray in champion blue + white 'Nissan' text) - Bought the last set of bilsteins from @Sydneykid and had them installed. Has been making some sounds on the rear but hopefully should be sorted out after this New Year break. - Regreased front caster rod bushings (poly bushes..) - Rear upper camber arms - Whiteline sway bars (BNF27Z 22mm + BNR11XXZ 24mm).  The rear sway bars are a bit short (ive read 50mm else where) but was still able to get them in.  Anyhows, I reckon suspension is sorted now. Maybe replace bushes (do have a set of front upper control arms from SK not installed yet) but should be okay for now. From now, I'm wanting to start working on the motor, drivetrain etc etc. Still debating on the order to go on and what to buy etc but: - ECU ( Haltech or Link ( Link states that it dont support A/T or AWD functions... Can anyone attest to this? ) - Highflow turbo ( ATR43ss2 ) - Intercooler ( Not decided yet, but cant find many good afoordable ones. Toshi says to opt for crossflow Japanese. Bit difficult this one, unless I get a returnflow Blitz from JJ? ) - Injectors ( Any recommendations ? I do have a nismo FPR ( Thanks SK ) ) - Seats - Tune by either Toshi or DVS To be fair, I did consider just keeping the stock turbo and nistuning it. Sat in a mates stock N, that had something like 200kw, and I reckon that felt more than enough. Maybe I should just go this route ahhaha. Too many choices.... Planning a trip down south, so wanting to just clean things up and make sure it gets to and from in one piece. Anything else specifically I should do before ? Cheers lads  
    • Must be for the car’s lucky charm 🤷🏽‍♂️ She runs fine, but it just seems to take about 1L less. Maybe I’ll have the oil sump dropped at some point to check if there is anything
