Sounds like it wants to start if you're getting backfiring and sputtering on crank. I would be checking the timing

I saw one of their ads and thought the same - but looking again, they appear to be LS manifolds. If they can do a complete 1UZ conversion for $3600 USD, I would question the quality of the parts used.

HC = hydrocarbons PPM = parts per million NOx = Nitrogens of Oxide EGR = Exhaust gas recycling WTH = What the hell? OE = Original equipment OBD1 = On Board Diagnostics Version1

What's your budget? Naturally aspirated or forced induction?

What Link ECU are you running? We had a big power WRX in our shop back in 2000 running Link Plus and 800cc injectors - if it didn't start first go, we then had the pull out the spark plugs and dry them off. Old tech and minimal control. I'm running 1000cc injectors via Haltech on my 1UZ and...

The most common cause for inoperative AC is gas leakage. When the gas pressure is insufficient, the system will be inhibited from operation. Every hose, component and connection in the system is potentially a source of leakage - however there are known methods of testing this and its recommended...

Very well. Due to the removal of the accumulator solenoid, the shift from neutral to drive is firm - but apart from that's its great. On the road, shifts are either smooth or violent depending on engine load. I'm pushing 400hp thru it (std internals) and it takes the abuse without any complaints.

The last few weeks have been momentus for the car - engineering certification, AUVIS inspection, and finally registration this morning. The car is 100% legal and we've just taken it for a cruise through the Royal National Park in Sydney. What an amazing feeling to have 5 years of hard work come...

The rest of the engine bay got a tidy up with, some hoses were trimmed to the "correct" length, and I made a hard pipe to run coolant from the turbo to the top of the thermostat housing.

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...
