Oh...didn't know that. My car was not equipped with an owners manual when I got it (weird huh? :icon_roll ). Just assumed it would be on the gauge. Sorry for the mis-info....

You can run 87 even if you are boosted, but I wouldn't recommend running 87 if you are boosting higher than stock.

Try unplugging the cold start injector and see if the problem goes away (easier said than done, I know...)

CWAPFACE: Don't worry man. If your car needed 93, it would say "PREMIUM UNLEADED FUEL ONLY" right on the gas gauge.

Along with the upgrades that disced listed I would also recommend a better intercooler, and a 3" exhaust. The most bang for the buck that I got was from my intercooler upgrade. I have a 60-1 CT26 and I went from 102 mph in the 1/4 @15 psi to 110 mph at the same boost level. An 8 mph increase in...

Very cool. Did you try the stock calipers too, or just go right for the AP's?

Anybody know if the MK4 TT front rotors swap in to a MK3?

Maybe try a torque strap? Kind of a compromise. Keep the engine from moving enough to tear the mounts, but keep the cushy rubber vibration isolation. As for handling, I would think that the 350-400lb engine moving maybe .5" would have a hard time upsetting the 4000lb girth of the mk3.

Make sure something didn't fall into the turbo inlet. Low boost and boost fluctuation are signs of a chewed up compressor wheel. As Anh said, it could also be wastegate or actuator related, or the boost controller itself.

The factory gauge is VERY slow to react for some reason. So I guess technically this is "normal", although very crappy.

Yep. That's the whole velocity thing. But if the pressure and speed of air increases, so does the temp. There is always a trade off with everything, and I too am just guessing. I have a 60-1 upgraded CT which can fill up the 3" piping pretty quick I'm sure. I haven't dyno'd any setup nor have I...

Yeah!!!! If your eyes don't get sucked out of your head first! Better have the windows down :eek3:

I have full 3" IC piping on my car and absolutely no complaints about spool. In fact, the larger piping really helped spool up. You need velocity at the head because the air has to squeeze past the valves, but smaller piping elsewhere is just a restriction. That could just be my opinion. I have...

Vey cool man. I planned to do this when my engine goes. Should have known that someone was already doing it....Good luck!!!!

If you measure the I.D. of the 3000 pipe inlet it is 1 7/8". The only other part of the whole intake system that is this small is the turbo outlet. IMO, if the 3" pipe fits, use it.

I did. You have to bypass the fuel pump resistor. The walbro pump won't run on the lower voltage from the resistor. Simply unplug the resistor and put a jumper wire (14 ga. or so...it draws a decent ammount of current) in the wire harness side of the plug, then you'll be good to go :bigthumb:
