Hi all Sau members. I have a question. I own a 96 Stagea s1. It's stock apart from air filter (k&n) not a pod. When I floor it, it kind of chokes for a while then changes gear n keeps going. What could the problem be? any ideas? It's really annoying.

Is it only in 1st? K&N pods are oiled, and have had bad experiences of the oil on them getting on the afm hotwire, a spray with a bit of electrical contact cleaner helps that out. Other things are make sure it's not overboosting and hitting boost cut (could be a line disconnected/not plumbed right), or other things I'd check are change spark plugs, if they're new, could be coilpacks giving out under load.

I'm gonna throw boost cut into the mix, have you

Got a gauge fitted?

Mine has a similar issue, had it when it was stock and still does it mow, just not as bad, with every breathing mod I've done it has gotten better.

I'm running standard boost control, full 3" turbo back system with a blitz pod, and my car makes 0.9 bar of boost, ie 12-13 psi. Maybe yours is like mine and it is over boosting.

If its airflow cut you'll know when you hit it. It's a complete engine cut, feels like the throttle got slammed closed and the engine revs down. By the way S1's don't have a boost cut, no way for the ecu to know the boost pressure.

Has it always felt this way? Or just recently? The stock setups on all rb's is fairly restrictive especially the exhaust, and the stock mapping doesn't favor consistent pull through the rev range, they tend to flatten out around 4500rpm.

hey guys thanks for replying. its not sparks as i have new lithium ones. i dont hink its air flow coz my revs stay high all the way till it changes gear and keeps driving normal. its not just in fisrt gear. i first noticed it couple months after i got it which is when i put my k&n on. so maybe it is my afm?

sorry i said my car is stock but i didnt think about but i have a 3" all the way and a hi-flow cat. I got the cat put on coz i thought that was the problem. then i got my dump pipe changed and that didnt fix it either. it already came with massive exhaust when i bought it.

so its either the FM or coilpacks?

ive researched abit n thought maybe the ecu needs tuning. i dont know how it works. this is my second car but my first turbo. man the stagea is awwesome.

thanks for your help guys. please keep helping. some mechanics dont even know what a stagea is.

Overboosting is usually caused by a dodgy boost controller, or when you have the stock set up could be vacuum lines not set up correctly.

I'd say it's either your coilpacks or AFM though. Easiest/cheapest option would be try to give the AFM a good clean with contact cleaner first.

Somewhere there is a thread on checking the soldered joints insde the AFM connector. I did not do that as I had a spare.

If cleaning the sensor wire does not fix it, see if you can find the fix it thread.

Hey Guys thanks your support and help. Got my stagea from mechanics yesterday and it's running smooth. I didn't know they go so hard. Turns out the choking problem was related to my spark plugs. I didn't install them properly.I just put them in and didn't do the whole right measurement thing. Don't kno what it's called. Thanks guys. I'm happy with my car now. Also got a boost gauge so I can keep a eye on turbo. also had manifold replaced coz I had a tink crack.

      Does this count as a time trial as well? I got all gold in the master super licence (1 lap time trial) and received a McLaren MP4/4 for my trouble.  If anyone else has done this, did you ride the wall right around the first long right hander at Lake Louise snow track to get gold? I couldn't do it any other way... best I could do without riding the was was within 2 tenths of the gold time.

      I definitely get the low power, sporty car to drive to smash gears but not be doing eleventy million miles an hour! It makes all the normal drives fun!   Rev match tune sounds like the funs! I didn't know the NC had a DBW throttle!   As for me, still have the Skyline, it still has the Barra in it. It's been pushed to the side of the workshop at the moment. Pretty much waiting on me finishing the wiring, and dropping new fuel lines in. Got myself an ACDC Tig end of last year so been teaching myself TIG welding to build a few things for the Skyline. The missus wrote off her GTB liberty at the end of last year, and got it back on salvage rights stupid cheap. It's also still registered, so will mean easier for me to take to the track already done most of the panel damage, just playing "clear the workshop" to make space to pull the motor and box out, fix some oil leaks, replace the clutch, and replace a few minor broken things.  Also got a Lathe at the start of the year, which is adding to the annoyance of no space, which is another reason I'm trying to build things to get more space, to get the Lathe back in a final home for it. It's a BIG lathe, can turn a 355mm diameter, and 1metre between centres... Got it at a steal! So between it and the TIG and old MIG welder, I'll be fabbing some fun little shit up But we've had a lot of shit stuff happening at home, so it's slow going getting things done. But one step at a time!

      I hadn't got that far, my main worry was the connection to the actual calipers themselves. I'm just using new (ish) stock brake lines in the stock setup. I've just had a stud welded to the knuckle that is a little lower than the original stud (so my knuckles have two studs each side) to not have it be stretched so far in previous BBK setups, so the "block" (in the second picture) mounts a little lower for me and I hope I don't need to change anything. I may have even changed the connection to the calipers in the past and have since forgotten I did that. I may not have. Guess how I'm gonna find out. Source: hopium

      It's more so I'm using the 1x piece line from HEL that goes from the body to the caliper. There's no middle block/mount like the HFM ones or the GKtech ones. There are certain angles/suspension compression where the line actually slightly contacts the ARB. Below of how mine sit (not my photo): How I want it:
