hi guy

i have a r33 gts-t. Ive had it boosted previously with a valve and it was set to 12psi (with stock cooler)

After the FMIC went in, i figured id be able to just wack the boost controller back in and it would sit at 12 like old times...How ever it seemed to just be running stock boost...so i adjust and adjusted till i got it back to where i wanted it. So its now at 11-12~ish.

Is it normal it did this? cause i had to wind the boost controller HEAPS to get it back up to 11-12.

Is this due to the persure loss, or is my boost controller stuffed or something?

No real dramas, just dont wanna hit boost then see my guage to 7+ 7+ 7+ 7+ if it is my controller lol

Thanks in advanced

do you have an aftermarket gauge?? (guessing you do) if you dont then the 7+ on the factory gauge is more like 1 bar. after my FMIC installed the other week my max boost went up 1 or 2 psi to around 12, so i wound it back down to 10. you got the opposite prob to me..

After thinking about it as i aim aimlesly bored at work (IT) LOL. i think i figured the problem ;) ill go home after work fix it...

I new there would be a difference after the FMIC, but i didnt think this much.

Cheers

I have just installed a fmic and found that my boost went up about 1-2psi but more so I found boost spike to be way more evident on a cooler night. Which in turn is either causing Rich and retard or missfires (fells like a miss to me but not sure what rich and retard feels like. Can someone explain?)

The above unpredictable boost issue could possibly be caused by my GFB manual bleed valve now getting a reading by being Tee'd into the BOV line. I intend to install my nipple in the I/C pipe very soon hoping this will decrease the cold night boost spiking effect somewhat.

All in all i did not touch the boost controller and boost did seem to rise slightly after the fmic installation.

RICOS - when you install a front mount , the boost becomes laggy because the air has a longer way to travel compared to the stock setup. i sugest you go and purchase an after marker boost gauge , to monitor your settings . and also psi is much easier to read .

yeah ellec boost controller is the only way to go. my greddy boost controller, bout 500 bucks, tells you max boost recorded after each throttle aplication ( boost spike). and the controller settings allow you to iorn out spikes easily, and you can flick back to stock boost too. oh and it also doubles as a digital boost guage

I have fixed my rich and retard issues by installing the nipple in the I/C piping before the t/b. no boost spikes only slightly and holds pretty steady MOST of the time. Previously was tee'd into the BOV line.

    • Nah - but you won't find anything on dismantling the seats in any such thing anyway.
    • Could be. Could also be that they sit around broken more. To be fair, you almost never see one driving around. I see more R chassis GTRs than the Renault ones.
    • Yeah. Nah. This is why I said My bold for my double emphasis. We're not talking about cars tuned to the edge of det here. We're talking about normal cars. Flame propagation speed and the amount of energy required to ignite the fuel are not significant factors when running at 1500-4000 rpm, and medium to light loads, like nearly every car on the road (except twin cab utes which are driven at 6k and 100% load all the time). There is no shortage of ignition energy available in any petrol engine. If there was, we'd all be in deep shit. The calorific value, on a volume basis, is significantly different, between 98 and 91, and that turns up immediately in consumption numbers. You can see the signal easily if you control for the other variables well enough, and/or collect enough stats. As to not seeing any benefit - we had a couple of EF and EL Falcons in the company fleet back in the late 90s and early 2000s. The EEC IV ECU in those things was particularly good at adding in timing as soon as knock headroom improved, which typically came from putting in some 95 or 98. The responsiveness and power improved noticeably, and the fuel consumption dropped considerably, just from going to 95. Less delta from there to 98 - almost not noticeable, compared to the big differences seen between 91 and 95. Way back in the day, when supermarkets first started selling fuel from their own stations, I did thousands of km in FNQ in a small Toyota. I can't remember if it was a Starlet or an early Yaris. Anyway - the supermarket servos were bringing in cheap fuel from Indonesia, and the other servos were still using locally refined gear. The fuel consumption was typically at least 5%, often as much as 8% worse on the Indo shit, presumably because they had a lot more oxygenated component in the brew, and were probably barely meeting the octane spec. Around the same time or maybe a bit later (like 25 years ago), I could tell the difference between Shell 98 and BP 98, and typically preferred to only use Shell then because the Skyline ran so much better on it. Years later I found the realtionship between them had swapped, as a consequence of yet more refinery closures. So I've only used BP 98 since. Although, I must say that I could not fault the odd tank of United 98 that I've run. It's probably the same stuff. It is also very important to remember that these findings are often dependent on region. With most of the refineries in Oz now dead, there's less variability in local stuff, and he majority of our fuels are not even refined here any more anyway. It probably depends more on which SE Asian refinery is currently cheapest to operate.
    • You don't have an R34 service manual for the body do you? Have found plenty for the engine and drivetrain but nothing else
    • 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.
