Conversion port adapter on sale for ¥68,000! This machined aluminum plate enables bolt-on use of RB26 throttles; the slightly dirty piece is the RB26 throttle assembly. The RB26 and RB20 differ completely in port spacing and stud positions, so modifying factory parts wasn't sufficient. The plate and a coolant-passage adapter are sold together for ¥68,000.

…cover! And the surge tank looks different too. Sharp-eyed readers will have noticed: the surge tank and throttles come wholesale from an RB26.

Despite both engines having six cylinders, the RB26 throttles do not bolt straight onto an RB20; port spacing and stud locations differ. Fukuda first tried cutting and joining the two intake manifolds, but their geometry differed too much for a simple modification. He instead made a port adapter to join the parts without modifying them, creating a convenient conversion kit. ‘The piping route is better, maintenance is easier, response is excellent, and the intake sound is wonderful,’ he said.

At ¥68,000 it's a little expensive, but we expect many inquiries.

TS Factory is also selling this manifold. Because installation requires rotating the turbo slightly, it comes with dedicated outlet and intake adapters for ¥178,000. Yes, expensive—but beautiful! ‘Parts like this are for people who appreciate them; they don't need to sell in huge numbers,’ Fukuda said, seemingly without much commercial ambition.

Still, it may quietly become popular. The owner is delighted with the shape, sound and gains across the rev range. That's what dedication to detail means.

These two parts definitely transform the intake and exhaust…

Looks good

Performs well

Factory RB26 six-throttle conversion

Just like an RB26! The six throttles look superb. The kit enabling use of the RB26 intake includes a port adapter and a coolant-line adapter, designed specifically for the RB20. This caption says around ¥60,000; the main price listing specifies ¥68,000. This car uses GT-R injectors, a GT2535 turbo, cams and a head gasket for around 350 hp.

Equipped with a stainless steel manifold

Look at the beautiful custom exhaust manifold! It was made specifically for this Cefiro by Altrack, a specialist known to enthusiasts. [Parenthetical reference to Drift Tengoku's Cefiro partly damaged.] Even when that car used an S14 turbo, it had Altrack's custom…

Throttles and…

…probably only us!

We may be the only ones who've made a part like this! Then you just need used RB26 parts…

…to complete it!

Altrack stainless steel exhaust manifold

Expensive, but I want it! Its beauty is sure to impress.

The manifold has a flex section in the number-one runner to prevent cracking. With an outlet conversion adapter, it costs ¥178,000 and accepts most RB-series turbos. Its shape improves flow and reportedly gives a sound like a 1JZ. This car has a GT2535; response improved substantially at both low and high rpm.

The sound is amazing! It fits an RB25 too, so how about putting one on Drift Tengoku's Cefiro?

…manifold. As you'd expect of a specialist, the bends and welds are beautiful. Fukuda proudly said, ‘It doesn't just look good; it flows incredibly well. With the GT2535, both low and high rpm feel better. And listen to the sound—it's like a 1JZ!’ The shape really is mesmerizing. An unusual detail is the flex section in the longest, number-one…

…runner. That extra compliance makes cracks at the collector less likely.

…that… [fragment]

…is certain. Whether increasing boost or moving to a bolt-on turbo, they offer appearance and performance together. RB20 owners: there's still plenty of life in this engine!
