Just looking at upgrading my turbo soon (rb20det), r32 gts-t Type Mcurrently have the following mods

3 inch turbo back exhaust

Unknown cat converter

pod filter/sectioned off

running 12 psi

FMIC

Performance suspension

Looking to make the thing a bit faster. Dont car about how many KW ill be pulling (expect 190-200)

Looking at the 25 series 2 turbo with the nylon wheel. Dunno if ill be able to afford a highflowed one unless i get 2nd hand or something, heard quite a few different prices but was hoping for somewhere around 800 or 900 installed.

Anyway just looking through the dyno thread sticky and most people just post KW's not 1/4 mile times, although one guy posted a time of 14.65.. which is like .15 better than a stock 32 gts-t. Weirded me out. Any one give me a rough idea of what i should expect to pull on the 1/4 (e.g. how much better than the stock 14.8) on some good quality performance tyres with performance suspension with my mods and the 33 turbo? Perhaps the time rough amount faster the highflowed is gonna be, would help to if u know that.

If its not significantly better then ill just leave it without the bigger turbo, and try to make do with what i have :D

Did try do a search but the criteria is to open and at the same time to specific to get some decent results. if anyone finds otherwise, feel free to post that link here for me :D

Some 0-100's would be handy to (stock gts-t's hitting that in about 6.9 i think)

You can get 160-170 on most RB20's running about 12-14psi depending on a few things...With a RB25 turbo your probably looking at about 180 mayb a few more at the rears...

As mad082 said, it comes down to driving, and how the car is setup. If you have crap tyres and crap suspension you cant expect to get a very good time because u will have trouble trying to put any of this power to the ground anyway regardless of what power your making. i would say high 13's is quite realistic with supporting mods. But that sed...all depends on the conditions on the day aswell.

Yeh tru all that, i think its reasonably well set up with full springs shocks under konig brand name (very damn hard suspension) and some 17X7 dunlop SPMAXX's which are top of the line (not to mention i weigh 55 kilos :)). Totally messed up somewhere in my readings somewhere though. Forgot to mention that i will Probably be running 14 psi on the new turbo with a remapped ecu but yeh. High 13's would be just wat i want, especially if i can get it with the series 2 turbo without having to have a highflowed one. The car could be quite detrimental to the ego's of stock $60000 performance cars everywhere with acceleration like that, sounds just about right :rolleyes:

running the extra 2 psi = no power gain and shorter turbine life? I have read of quite a few people running 14 psi so i assumed it would be relatively safe.. Cant see how it wouldnt equal a power gain though.. Up to a point more psi = more power.. you could probably get more power all the way until 20 or something id say (read something somewhere about flow and such which seemed to imply that too much compression would equal slow flow or impeded flow rates, something like that)

correct me if im wrong

Edited by r32 gts-turbo
you wont be running 14psi for long, maybe 6 months to a year. Wont you be just adding a hole lot of heat for no power gain

Its on an RB20... just incase you've missed that posted a dozen times.

RB20 you can run a little more than the R33

whoa whicked if i can hit something like that ill be very happy, time to start looking around for a turbo to lob on. Guess the for sale section is a good place hehe.

My old R32 with remapped ECU (thanks to Matt Spry) and standard turbo pushing 12psi managed a 14.3 on my first run with G-Tech. Tuned for 15psi I managed a number of runs between 13.7 and 13.9 (again with G-Tech).

Yeh tru all that, i think its reasonably well set up with full springs shocks under konig brand name (very damn hard suspension) and some 17X7 dunlop SPMAXX's which are top of the line \

Hard suspension will make your time worse, and 17x7 are the size of your rims, not tyres.

I am taking this from another thread which may have a generous dyno, but still none the less it prooves 160-170rwkw is easy (ive seen that on stock rb20 turbs) and 180+rwkw is a good goal for an rb20 with 33 turbo, obviously the 34 turbo will make a tiny bit more than a 33 turbo as im sure you aware.

You should be able to do a mid 13 with an rb25 turbs if you are a good driver :)

You can run a little more boost on the RB20 with the RB25 turbo as the engine is smaller in size with supporting mods and 14psi 200rwkw is probably possible but im not sure how long the turbo would last at that boost level.

I managed a 13.6@105 with a crap 2.4 second 60 footer on a 30 degree day, with my R33 first time at drags. So in your case with similar power less weight better tyres and suspention high 12's may not be out of the question.

Hard suspension will make your time worse, and 17x7 are the size of your rims, not tyres.

Ohh really? I suppose it IS set up for handling, uhm so tighter suspension = more bouncing, is that it? Wouldnt tighter suspension stop the sag more and help distribute weight around more evenly on take off. Not sure on suspension stuff

And yeh i know 17X7 is the size of my rims, the car was nowhere near me. There 225/45R17 Dunlop SPMAXX's which is basically dunlops top performance tyre so i think there cool for a bit.

Curious though, you 2 guys who ran mid 13's were your 33 turbo's high flowed? series 2 or 1?

Thanks (had to spend $1000 getting a new computer to get onto SAU, just when the turbo was within my grasp demit)

And yeh i know 17X7 is the size of my rims, ill post tyre size a lil later on, the car was nowhere near me. Its still not near me but they are very well fitted (did em myself :P) and definitely not to small for the rim, the sidewalls buldge slightly as a rim protector (with to thin a tyre they won't sit out) so there definitely wide enough to be putting the power down alright (can drop the clutch at about 4k RPM and get pretty good pickup).

do a search for posts by sydney in regards to drag suspention.

cheers

Well i made 162rwkw @ 14psi on a stock RB20 turbo.

Full exhaust, re-map, fuel pump and thats about it.

Dunno how but hey i was happy for so little mods.

But there are always those freak motors around etc so i'd be expecting maybe 170ish from a R33 turbo but you never know i suppose so whack it on the dyno and find out!

    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
    • Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣
    • After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.
