I bought the wastegate online for 19,800 yen. The outlet connection was just an opening about the size of two pipes. A senior told me, “You should separate the bypass gas coming from the gate,” so I welded in a divider plate myself! I used 3-mm steel plate, removing, adjusting, and extending it three times. It makes the gate sound quieter and adds power—great!
I've always driven naturally aspirated cars, so I wanted to prioritize response. I added an S13 turbo to the NA engine to make a high-compression turbo setup! The NA engine has more cam lift and a slightly larger throttle, which are advantages. Boost is 0.5 kg/cm², and with the stock S15 ECU it makes about 220 horsepower. It still feels like an NA, but with more torque throughout the range!

Silver…
People ask, “Is that a…?” Actually, I've just welded the R35 airflow meter adapter facing downward so you can't see it. It goes unnoticed more often than you'd expect. The body color is a custom dark green that Mr. Gunji painted for me!

A one-off intake that looks like it's running without an airflow meter!
Using an R35 airflow meter is popular on SR engines, but turning the adapter downward is a small clever touch…
Comment
Use similar colors for wrap painting!
…that makes the engine bay look much cleaner. It seems to make maintenance a little harder, but prioritizing good looks is fine too!
I used wrap painting on the timing-belt and battery covers. Normally you'd use black as the base, but I like pink, so I used white as the base, applied the wrap effect, then painted over it with pink. Doesn't it look nice, like a wrap effect in similar colors?
Let me show you…

It's a shame I can't…
The divider panel is the key to the glove box!

The white areas look pale pink, and the silver parts look deep red—it's beautiful. It has real depth and even looks a bit like candy paint. This is something other…

It's a paint technique that makes you want to try it in your own car's color!

Without the divider, exhaust smells fill the cabin even at idle. He said, “A wastegate is an amazing, inexpensive part that gives you the gate sound,” but this extra step seems important…

…indeed.
The intercooler I bought online had badly dented pipes and was leaking. I had a shop make custom piping with my name on it, so even if I drop the intercooler, I'll know it's mine!
…for better response
A single-piston caliper…

I made it myself…
You can actually read “Golgo” correctly! Even the name on the plywood under-panel…

…and he even cut out a tow hook, which is a meticulous touch.
It changes the brake touch!
I combined pieces of steel plate to make a master-cylinder stopper. The contact point against the master cylinder can be adjusted with a bolt and nut. It worked better than I expected and made the brakes feel much stronger…

The cylinder…

He also swapped in the S14 ignition system, which costs about one-quarter as much as the stock S15 direct ignition, so repairs are cheaper if it fails…

…is another advantage. The total cost of the turbo conversion, including harness modifications, was about 270,000 yen. He chose an S13 turbo because it was 20,000 yen cheaper than the S14 turbo.
