Mine started to go lean after 12.5psi, it made 152rwkw.

A new fuel pump was required for 14psi as the old one was a little tired. As expected, the car was 10-11yrs old at the time.

I ran the turbo at 15psi then 16psi towards the end. It was fine. Providing the tuning is ok and egt's are kept as low as possible (no lean, no detonation, no super rich, no track or extended periods of WOT)

i was told that a safe boost would be bout 11 to 12 psi, but once you put an exhaust and pod filter the boost will rise to that amount from stock which is 9-10 which i was told by neil_se

The r32 wastegate actuator is different to other models so stock boost is 9-10psi, on an r33 and s13 its 7-8psi, so 11-12psi with your mods is pretty normal.

hope this helps.

"no super rich" <---- What does super rich do to EGT's?

Run it super rich (highly unlikely) and egt's will go high.

I shouldnt hav included it really as we won't see rich conditions as such.

No idea what afr that would be at as its theory.

Google EGT's... Quite interesting.

    • Let's hope that's not a copy pump either. There were so many copies of them back in the day.
    • Damn it, I was at work last night, and stayed in a room there during the storm with the car outside, but undercover, I just went downstairs and well....there was a large steel locker that has come from some place last night, it wasn't anywhere I could see yesterday, and yeap, it landed on the fraking car....of course it did..... LOL So, I'll need to take it back for paint and panel, luckily it was only the boot that took the hit, so it could have been worse Serves me right for staying at work and getting on the cans with some of the boys
    • Yeah, really happy with how it all turned out As for aftermarket lip, nah, I'm not really a fan for practically reasons on a street car that gets driven everywhere  I did have the full lower kit on my 2015 STI, but found the front lip scrapped alot, even at stock 4x4ish ride height As the NC sits now, with the lowest point of the car at 110mm, so just legal, some steep driveways and steep speed humps will still "just" scrap those little plastic OEM air dam thingies on the undertray just before the front wheels
    • Here's one I help build and tuned a decade ago, Garrett  GTX3071R Gen 1, T3 twin scroll 0.83 rear housing. Went from larger 272 cams down to smaller Tomei Poncams to help with the low end. S13 non VCT motor. Car was purpose built for the track, hence low down was the focus. Note the actual dyno chart shows lower boost, however the EBC and boost gauge showed 1.9Bar (Ignore the torque, I was young and didn't know how to set derived torque)  
    • I’m doing some side developments on SR20det S13 engines, its one my hobby cars used it to compare flow capacity of some smaller size wheels. SR20det is one of another JDM legendary engines I'm sure there are plenty of SR enthusiasts on this forum, I will share results some common turbo configurations here. a quick run down of what the car is: Wide body 180sx Type X with black top engine (blue). It has: Stock bottom end Haltech 1500 ECU 5-0 motorsports trigger kit Kelford SR20DET Beehive Spring with Titanium Retainers Kelford Cams SR20DET S13 188-B 268/272 Cams G25-660 Turbocharger in T2 .64 rear housing internally gated ARP Head studs MLS head gasket 1000CC ID injectors Walbro 450L Fuel pump Front mount cooler kit JJR’s 3 inches turbo back exhaust (its too short for the 180sx it had to be extended) Pump 98 fuel Hub Dyno tune So far made 270rwkws at 22psi full boost by 4500RPM. Engine is very knock limited hence a pretty bad looking top end. From previous experiences it seems like SR20dets are happier with bigger size turbine, some thing like a GT30 would make way better top end, but on same time response is lost. It won't be a problem with S15 VCT engines. I'll be testing alternative turbine housing, turbine wheel and possibly dump pipe options for extra flow to resolve the problem and of course E85 would resolve all the issues.
