What is better 1JZ VVTi or non VVTi?
At the ‘BPU’ level (intercooler, exhaust, upped boost) the VVTi is much better, as it spools much faster and makes more torque and makes a bit more power with those modifications vs the early 1JZ-GTE.
Is 1jzgte VVTi interference?
A citation from a credible source or actual proof will be needed to quote that the 1JZ-GTE VVTi is now an interference motor from just a half point compression increase.
How much HP does a 2JZ GTE VVTi have?
The 2JZ-GTE’s naturally aspirated and easier-to-find older sibling, the 2JZ-GE, is based upon the same short-block and nearly identical but higher-compression rotating assembly, but as far as Toyota’s concerned, is only good for about 230 hp.
How much power can a 1JZ VVTI handle?
A general rule of thumb is that the 1JZ stock bottom end is good for about 650-700 horsepower, and the stock 2JZ bottom end is good for about 800 horsepower.
Are 1JZ engines reliable?
The most durable and reliable 1JZ is a simple non-VVT-i 1JZ-GE engine. The longevity is well over 200,000 miles (320,000 km), but they are old now and find one of these engines in a good shape is not an easy task.

Is 2JZ GTE VVTI interference?

Is the VVTI 2JZ an interference engine?
8. No interference here: The 2JZ-GTE is based off of a non-interference valvetrain, which means that if, say, that timing belt slips because you decided those maintenance intervals didn’t apply to you, those valves and pistons will never get any better acquainted with one another than they already have been.
What Lexus has a 1JZ?
Well before this 2002 Lexus IS300 was powered by Toyota’s venerable workhorse 1JZ, and prior to it looking clean enough to nab a handful of trophies at a local car show, it carried mismatched panels, some off-road scars, and an eager new owner with a headful of ideas.
How many turbos does a 1JZ have?
The first generation 1JZ-GTE employs twin CT12A turbochargers arranged in parallel and blowing through a side-mount or front mount air-to-air intercooler. With an 8.5:1 static compression ratio, the factory quoted power and torque outputs are 280 PS (206 kW; 276 hp) at 6200 rpm and 363 N⋅m (268 lbf⋅ft) at 4800 rpm.
