This is what I got yesterday:
Dear Mr Hightower.
Thank you for your e-mail and your concern for our TLDI engine.
As to the upper HP model of TLDI engine, we will develop the model, but we cannot say if the engine will be released at present.
We are sorry that we cannot reply to your question clearly and your kind understanding would be appreciated.
Thank you and best regards
