Hiya,

I am currently running my 95 R33 series I with the only mods I am aware of being A full turbo back HKS exhaust and HKS air pod.... I am very happy with both of these ......

I am looking at buying a second hand GTR cooler and an apexi AVC-R to install at the same time...

My questions are if I install both the cooler and boost controller along with my mods I already have what could I turn the boost up to safely ( still wanting a decent increase though ), I was thinking around 12 ish???? ( its around 7 standard isnt it??? ) ...

Is it worth turning the boost up that much ... ie will I get a noticable increase in power ???? ....

And is there anything else that should be improved if I was going to go ahead with the increase in boost????

Thanks

Brett

If you are running a stock Turbo then leave your boost at about 10.5-11.0 as the stock turbo can only handle 12psi (and no point running it constantly at full boost).

I've got a '95 S1 which has done 65,000km and purrs like it should. Cat-back exhaust, FMIC, boost controller and a HKS Airpod.

@ 7psi i got 169rwkw

@ 12psi i got 192rwkw

So u could expect similar results from your mods.

I have a dual boost controller on my r33 s1 and run 13.5psi Hi and 9 psi low the standard turb on a s1 is good for only 14 psi and thes td turbo on a s2 is good for 12 psi due to its plastic inlet wheel.

my only problem is on a hot day I hit the fuel cut defender on my hi boost setting.

Thanks for the replies.....

With the AVC-R I am planning on having the two presets at something like 7 psi for normal driving which should be what I am running now I guess.... and the second preset at about 12 psi which I only want to use when I want to blow someone away at the lights :) So I dont really have to worry about running too high a boost over a long period of time as it will only be used in short spurts....

You can run the turbo on 13.5 no worries, but the car is gonna run real rich, therefor your power increase aint gonna be that noticable. Better off getting some sort of ecu, S-afc.

And trust me, You'll never run low boost for "normal driving"

Ahhh crap.... If I get a S-AFC as well then I will have to find a home for that also!!!! I don't really want these Apexi computers visible as I believe they will be a huge theft magnet. Hmmm I am going to need to do some more thought on this :P

Yeah I was thinking along similar lines.... I am wondering if I can fit both the S-AFC and AVC-R in the glove box... then all I have to do is open the glove box when I want to change the boost....

Hehe I can picture it now..... You pull up at the lights and there is some nutter next to you wanting to give it to you at the lights and the first thing you do is jump for the glove box!!!! He would be thinking WTF :confused:

hehe that would be cool... :P

On the other hand you wouldnt have a glove box anymore but who really uses it anyway!!!

    • 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.
