As for today, I just stopped by a custom fitting shop to get some fittings for the fuel pressure regulator. I will be placing the FPR on the passenger side and bypass the OEM return line. The driver side (that where the return line houses) is very tight and hard to work with.

I got 6-AN inlet and outlet with clamps. I would like to increase the fuel pressure to about 5 to 7 psi above OEM setting. High fuel pressure will cool down the conbustion chambers, because i dont have an intercooler yet.

Installed my Aeromotive FPR last night. The OEM return is deleted, now i am using Earl's SS Braided Lines. Currently, the Aeromotive FPR is set at 40 psi at idle. The car felt slightly faster at low end.

I will have some pictures tomorrow.

Aeromotive Universal Adjustable Fuel Pressure Regulator (AFPR) is widely used in the Supra MKIII. You also notice the B&M Mini fuel pressure gauge.

Methanol injection plastic tubes were replaced with SS braided line. Safety is the KEY. Its better to be safe than sorry.

This is the Methanol Injection pump. Noticed all lines are braided with AN fittings. I am waiting for a special order JAZ Fuel Cell. Its 2 qts. and it should fit perfectly over the pump. The fuel cell is coming Monday.

This is the new turbo inlet for my turbos. This will help when very heavy rain and water on the road. The tubes are 2.25" and its loop around the inner fender. Yes, I think its slightly restricted, but space is hard to find. I plan to run my car with the extension tubes during rainly season and take it out during summer.

That is a dangerous *****. I dont want to mess with that stuff. I know a family got burn very bad from a propane explosion. They were living on the 2nd floor in a apt. The whole apt blow up and my friends were burned very bad. They all jump from the 2nd floor.

Propane might be good stuff, but not for me. Beside, my is a dailydriver.

gasoline is dangerous too.

no, you dont get it. it is FOR daily drivers. the whole point of it over alky injection is that you dont have to refill it all the time. it uses a small 5lb tank the size of a basketball. the tank lasts about 70+ passes at the track, and like forever on the street compared to alky injection.

if you put it together right, put teflon tape on the solenoid connections, you will never have a problem, for $50 you can also buy a propane leak detector and put it back there, but it *wont* leak unless you mess up. Dangerous depends on YOU. Just like those people who caught themselves on fire putting gas in their car.. never happened to me, but then again im smart enough to know about static electricity.

Currently, I am trying to get two Saab Side Mount Intercoolers from ebay. They will be mounted in the fender walls. After that, I will need an after market torque converter. My TC is slipping.

LS400,

The K&N Filter is just above the intake tube. You missed it when you take the picture. If your camera go up about few more inches, you will see the filter. It is hiden under the fender. Its great when heavy rain.

OK,

Got some silicon vacuum lines and a new pressure switch. Clean and rmor-all my engine bay. Idling at 1600 rpm was fixed yesterday. It was the Idle Valve Control. This is the best looking this car ever experience. This car is really to experience 10 psi very soon.
