Builds my turbo build (1 Viewer)

ok so my friend have a lx450 he will let me use his o2sensors maf ecu to see if i can make any differents on my afr thanks guys!


Dusty,

i was using a 11psi spring on my Tial 50mm Blowoff valve and it was making the same noise. the spring was to hard to open so i replaced for a 6 psi and its working very good plus sounds very nice so replace it

Just an FYI, we have a known issue with our engine harnesses. I'm swapping in a brand new one before I even touch a match to mine.

LT, are you refering to the burn thru adjacent to the EGR pipe as the known issue or is there another problem with the harness?

Thanks peter

Yes, all the wiring for the engine management system goes through that area with the exception of the MAF sensor.

When you let off the gas abruptly while under full boost the throttle plate slams shut and that loads up the compressor side of things stalling the compressor. That stall transfers over to the turbine restricting the exhaust side of the engine producing a lot of back pressure. That back pressure will kill the engine

thinking a bit more about it .. Dusty .. are you seen significant turbo spike .. ?

hey guys how big of tires i can fit in my LC? i have Old Man Emu Heavy Load 2.5" kit and 2inch body lift thanks!!

nice idea on too small a BOV Rick. i think ill look for a bigger one and give it a go.

i dont know if the pressure spikes or not. durring those hairy situations i look at only the road.

by the way i smashes the lexus up pretty good this weekend. all the doors still open though

Was the issue ever resolved here?

well i replaced o2 sensors, ecm,maf sensor,fuel filter,relay,clean the injectors,i check timing,i got a scanII, and the truck in close loop was 14.7 afr so i dont understand how people said the truck is all ways rich i even install a wide band in my friends lc and was the same 14.7afr so i think im not the only person runing normal in close loop. so i decided to buy the URD o2sensor calibrator and now under boost is 12.2 close loop and 11.6 open loop and 13.7 under vacuum

What afr is ideal?

What afr is ideal?

it depends .. boost, temp .. WOT .. IMOP 11.2 - 11.6 or so .. WOT open loop 10 plus PSI

well my LC under boost the egt 1350 close loop, open loop is 1300 and under vac 1100 to 1200 and my intake temp is 79 to 85 and last weekend i went offroad and the max was 105 i think is good plus im going to install the snorkel some time next month i think will help to keep my intake temperature low.


5.5 to 6 psi only
