Has anyone ever made a conversion to a sequential tranny for street/track use? If so, what engine, and what tranny, and how much (money and time) approx.

 

a friend of mine did one on his TT supra, Level 10 transmissions in NJ did it for him, like about $12K includes computer controller.

for hondas, nope ... only pro racers with good $ sponsor budget do that kind of stuff. I also know QUAIFFE sells one for Hondas for around $18K ... thatst he price of a used Type R isn;t it ?

greg i thought the quaife unit was just a standard dog gear trans with custom gears and FD?
the only semi sequential i know of is made by

5 Zigen-twin mode clutch system and
5 Zigen Twin Mode Clutch System

5Zigen releases the Twin Mode Clutch System aftermarket transmission upgrade that offers the best of both transmission worlds: manual & automatic! Such an interchangeability option in a vehicle is a luxury only offered on production models like Porsche's acclaimed Tiptronic, Alfa Romeo's superb Selespeed, and Mitsubishi's innovative INVECS II. This upgrade option provides a driver an automatic transmission mode while driving in heavy downtown traffic or in a traffic jam. It also allows the driver to switch to a manual transmission mode when driving in suburban town areas or when the driver is attacking the slopes & bends on challenging mountain & canyon roads.
The above is achieved by having an on/off switch on the shift ****. Depressing the switch turns the system on, and the transmission will act like a clutch-less shifter, where each push of the gear **** will raises a gear, and each pull of the gear **** will knock down a gear.
The switch on the gear **** is to activate an actuator connected to the transmission oil pressure line. Actuation is controlled by a motor which mechanically disengage the clutch. Such an action will convert the manual transmission state into a semi-automatic transmission state. The amount of adjustability for clutch cut-off is allowed by the actuating mechanism during the twin mode system's set-up.
The Twin Mode Clutch System comes with a computer-controlled pump that controls the clutch's oil pressure, and cables that are used to actuate the switching system. Control in semi-clutch state is made possible by activating the switch on the gear **** and letting the computer to control the actuation.
As a result, interchangeability between M/T & A/T is made possible by turning on the switch. Gear changes are made by turning of the switch. M/T & A/T are two different transmission systems but with the installation from this kit's computer controlled oil pressure pump to on & off the clutch system, the Twin Mode Clutch System becomes a reality. The computer works by reading driving parameters like vehicle speed, engine RPM, and accelerator, clutch, and brake pedals actuation. The ROM chip in the computer differs according to vehicle model.
For vehicles with twin & triple plate clutch systems, optional items (JPY 20,000) are required. Please enquire when placing orders.
