So, I'm using genuine ignition coils from a Lexus ISF (part# 90919-02260) - they slot into the tubes nicely but the fastener hole is slightly off the threads in the rocker cover. I wasn't worried about this as the coils clip firmly onto the top of the spark plugs and need to be pulled firmly to...

I can imagine there isn't much room around the engine in a Cobra body - but there must be a heap underneath if you can squeeze in twin low mount turbos under each side! In the majority of cars with a turbo 1UZ, the turbo/s are placed in front of the engine due to the positioning of the engine...

For both fuel system and ECU, that all depends on what your budget is and what you're trying to achieve. Have a read of this to see where you sit in the scheme of things. Lexus V8 1UZFE Injectors and Upgrades – Lextreme If all you want to do is run the engine, then most entry level aftermarket...

Venus is the engine control module Neptune is the transmission control module https://spitronics.com/ Sounds like it needs a tune or has a problem. Spitronics are a South African - I'm sure if you call or email them, they can recommend a reseller/tuner in your area.

I'd be interested to know: How much boost does your setup make Has the car been on a dyno and what was the result Does the half turbo, intercooler and piping make any noticeable restriction when you're off boost?

To the suction port of the charcoal canister

This is a BVSV (Bi-Metal Vacuum Switching Valve) that inhibits the vacuum to the charcoal canister when the coolant temperature is cold. I struggle to understand why Toyota put things like this on their engines. The solenoid it feeds is controlled by the ECU and it also has an engine temp input...

"The engine is cutting out" is a very broad statement, as there are literally dozens of reasons why an engine will cut out - and diagnosis is a process of elimination, working through each potential cause to confirm whether it is (or isn't) the cause. If the fault has been detected by the ECU...

Engine swaps, even seemingly straightforward and "bolt in" swaps, always come with complications and added costs. Will the extra cubes really deliver what you're after... and given the improvements that can be found in headers and some tuning, are the cubes necessary? The 1UZ is a strong motor...

Should be fine - 1UZs have long inlet runners and make good torque down low + the TR7 is a pretty light car.

They are all 1UZ-FE Pre-1995 is early 1995 and onwards is late 1997 added VVTi cylinder heads Upper/lower case doesn't matter - everyone here knows what you're talking about. But, all Toyota engine codes are uppercase

Hi - with your tire size and diff ratio, this should be your speed chart. KPH = RPM / gear ratio / diff ratio * tyre circumference * 60 / 1000000 MPH = as above * 0.62 Mine is slightly slower (3.69 diff and 245/45R17 tyres) and it drives and cruises just fine.

After some more testing, the engine was faster to heat up (past 95c) and taking longer to cool down. In theory, the coolant velocity through the front bypass pipe would pull fluid from the turbo back into the radiator. Turns out that Setup 1 (below) causes the outlet flow out of the engine to...

Edit: 240kw

The 2 wire IAC Solenoid does buzz a little when the engine isn't running but its imperceivable as soon as the engine starts. The closed loop on it works very well. I did some data logging today and the air temps sit around 30-35 degrees when running 6psi - but the sensor seems to heat soak a...

While there is much more to do on the car before it's finished, I am nearing the point where it's ready for dyno tuning. One of the main concerns I had was the cooling system. The current setup is: Chasebays Radiator with dual pass core 22" x 17" x 3” (W/H/D) 20AN fittings with 1.25” hoses 16”...

When you say "it won't start", do you mean that: a) the engine cranks over but won't fire up, or b) the engine won't even crank over Engine won't start is a fairly broad statement - but the answer to the question above will determine what happens next... There is a logical process to...

P/N for Igniters (UCF10 09.1991 to 10.1994) are 89621-12010 and 89621-12050 You need one of each. Not sure if they're swappable... someone smarter than me would probably know

There are two or three versions of the LS400 harness, and two versions of SC400 harness. You may get lucky with the ECU plugs but there can be differences with emissions gear. How badly damaged is your original harness?
