14psi ?? Interesting....

Using the stock turbo and stock ECU im currently at 272rwhp. I'm still quite confident I can get the stock turbo much higher than that (well 285+ rwhp) with probably another $2500-3000 of various minor mods.

Jet..

~200rwkw is pretty much spot on for a RB25DET with a standard turbo running 14psi, aftermarket ecu, fmic & exhaust.

Some RB25DET's are freaks and make ~200rwkw with the above except without the aftermarket ecu.

i.e Bugalugs that also ran a 13.4 1/4 recently.

If I had a RB25DET turbo i'd be running it at 17psi.

You can't really compare the 14psi limit of ceramic turbo's when using a larger turbo on a smaller motor as at 14psi on the smaller motor the shaft speed of the turbo isn't going to be anywhere near as fast as it is on the larger motor. So up the boost so it is :D

Heat also kills ceramic turbo's.

So if you hammer it on a track day be prepared to loose a turbo.

I have noticed a trend with turbo's that are factory fitted.

For example the RB20DET makes 160kw at the flywheel, when boosted to approx 1bar they make 160-170kw at the rear wheels.

Same with the RB25DET's, they make approx 190kw at the flywheel and when boosted they also make around 190-200kw at the rear wheels.

Stock turbo and Stock ECU?

What mods u have?

Joel, this discussion will probably lead to the accuracy of the dynos. some dyno show better result than others. my car have all the mods you'v mentioned and it made 165rwkw at 14psi on a particular dyno. 165rwkw and 200rwkw is a huge difference, but in fact they might be generating the same power. you get my point?

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
