What's New in Trans4motor R

1.0.5

February 9, 2026

SOHC 2-valve engines now support multi-cylinder (3+) simulation. Added Port Layout setting: Reverse-flow / Cross-flow (e.g., DATSUN L28). Added Double-row Timing Chain. We’ve also published new SOHC examples on the Engine Sharing site: • NISSAN / DATSUN: Fairlady Z(280Z/S30) / L28 (Reverse-flow) • BMW: 2002 ti / M10 (Cross-flow) Download them and start using them right away.

Needs work

It has nothing to do with actual building

インテグラのエンジンが…

1998ccインテグラTYPE_Rのゲーム内では5速ミッションになっているのですが
実車は6速ミッションですし、エンジンは9000回転まで回ります。修正してください。

Response from developer

ご指摘ありがとうございます。 エンジン共有サイトのデータをご利用の場合、公式データに加えて有志の皆様が善意で公開してくださるデータも多く、設定が実車スペックと異なる場合がございます。立ち上げたばかりの共有コミュニティですので、差し支えなければ、今後の成長を一緒に見守っていただければ幸いです。 実車同様の「6速/9000rpm」などの情報をお持ちの場合は、編集画面の「最高回転数」および「変速機/ギア数」より数値の調整も可能です。 設定方法にご不明な点がございましたら、公式ページの「取説・ヘルプ」をご参照されるか、「お問い合わせ」からご質問ください。引き続き「Trans4motor R」をよろしくお願いいたします。

Yahhhhh

This game is so much better than the first one I played it for hours without getting bored you guys are amazing developers, but I asked one thing make me able to like add turbos and superchargers to my engines that would make it top-tier

バグ対応は早い

初期バージョンは本当に酷かったですが、不具合が少しずつ改善されている点は評価できます。

点火時期設定などをスライダー/ボタンだけではなく文字入力できる様にして欲しいのと、ミッションの段数変更(9速ATミッションなど)ができるともっと良いと思います

Response from developer

ご意見を頂戴しました。ご不便をおかけし申し訳ございません。ご指摘の「点火間隔」「最高回転数(レブリミット相当)」については修正・機能追加を行い、v1.0.1 として現在App Storeで公開済みです。 また数値調整は、スライダー左右の「+/-」ボタンで最小単位で変更でき、長押しで連続変更もできます。ぜひアップデートしてお試しください。

Thank you guys so much!

I absolutely love this game and its improvements from the original game. In the original, all of the engine sounded like vacuum cleaners lol. But now, changing engine dynamics actually change the way engines sound! Thank you guys.

Hello, this is an edit from the original review, and all I ask is one more feature. It’s more of an aesthetically active feature rather than an actual performance fix, but I wish the ability to change the intake and exhaust orientation on syncromesh mounted engines. The option still exists on the screen, but does not affect anything when toggled. Another note, I WOULD ADORE if you guys added diesel engines (at least for I3, I4, I6, and V8). And 2 strokes up to 4 cylinders. That aside, I see myself buying more games from you guys in the future with production quality of this manner.
