Open down pipe will raise the pressure a few PSI. Stock turbo 'should' be able to run around 11-12 PSI without hitting fuel cut. Do you have any CELs? Have you checked for boost leaks?

Lexus afm will raise fuel cut a tad bit. Going MAFT PRO with speed density will raise it even further when tuned. To remove safely, standalone that is properly tuned.

Think of it this way, instead of the turbo working for only 15 PSI, it has to go up to 18-19 PSI to get the desired 15 PSI.

by playing with the afm screw and the afpr, you might be able to keep the vF happy.

play with the air bypass screw, it'll lean you out though.

Greedy profec b spec 2 has a setting to allow boost to rise slowly. The SET PSI and GAIN control where the solenoid starts to open and how fast it opens. I like the greedy because with the boost controller turned all the way down, all the settings on 0, it spools the turbo as if it's only on the...

Electrical nightmare..

34 is fuel cut. Fuel cut on 7ms normally happen when either a boost leak is present or as you found out, a wrongly setup boost controller. Look at the description of code 34 "Abnormal boost pressure"

Considering this car seems to have been forgotten for most of its life..

No no no, do NOT use a FCD. Get around fuel cut the proper way. Lexus afm, walbro 255 or bosch 044, full 3" exhaust with elbow, 550cc injectors and a adjustable fuel pressure regulator with the j-tube bypassed will make for a fun daily. I'm running basically a full bolt on setup with a 57 trim...

Curious to see how the flywheel looks.. 23 years old and only 19k miles. So the car has had maybe 5 oil changes its whole life? Mmm..

So glad you corrected yourself. Also, don't check the cylinder while it's just at TDC, check it on the top of the power stroke so you know for sure both valves are seated.

What coating is that on the pistons? I'm planning on running ross pistons with ceramic coated tops and teflon coated skirts on stress relieved pauter rods going to a micro polished knife edged and balanced crank.

If you put that banjo bolt in first while lightly lifting up on the turbo, it'll go in a tad bit easier. Don't bolt the turbo down without having all the fittings connected, makes it much worse IMO

Stock worn out suspension. I've got a set of kyb gr2 waiting to be put on but I'm not replacing those til I get sub frame bushings and control arm bushings. I'll do it all at one shot and put in eibach springs then reset my camber.

That's why we use 220 3-phase :D The building actually has 256volts but has to be brought down as the machines don't like much more than 206 and it has to be a very clean signal. You should of seen the guys face when we requested a 60kw/hr transformer for one building when the entire street...

What does it take to make these cars break 12.99? I keep being told over and over that my mods will not break 12.99. Yes, I plan on running my car at the track but it's roughly 2 hours away and I've got a few more things I want done before I even do a shake down at the track. So the question...

Well done, 700+ on any setup deserves a pat on the back. It'll be interesting to see how much more you'll get out of a bigger turbine housing.

I didn't know that I had to give an exact number when regarding how much the PSI was raised. And since your car has head work, it's not in this topic. Apparently you've only had minor failures, and did you drive those hundreds of miles? Remind me never to buy a block or head from you. Toss a...

im mobile right now but I will be replying to this post in a bit more detail.. first, OP you seem rather stupid. you want to push an old tired engine that is showing you signs of dying. second, 10 psi is done simply by changing to a better air filter and a full exhaust. I dont mean crush bent...
