In mid 2005,  I finally got my 20B running in the Series 4 rx7 Covertable, this is running on a Mircotech LTXs12, 6 Bosch Coils, Bosch fuel pump, STD Cosmo Twin turbos, std Cosmo Intercooler, custom made pipe work to & from Intercooler

Turbo pipe work cut and re-welded

Exhaust / turbo manifold, which had a flapper valve in it, so the exhaust could be changed for one turbo to another,--was removed all together.

This RX7 Convertable, is a one of the first of the series 4's, made in 1987, this was imported in to New Zealand in 1997, to date (01/03/06) I'ave done about 65,000 miles since getting it form a car dealer in mid 2001.
It had a 13b turbo motor in it when first bought, then two rebuilt 13b's followed by  a Cosmo 13brew, and then a "B" series 20b. Which in the last 6 months I'ave clocked up 10,000 miles.

New things that will get added or changed soon, --Big front mount Intercooler, Bigger Radiator, Bonnet (Hood) to be replaced, Rear Diff & Rear end Bushs to be replaced, Bigger fuel pump & lines, and a wastegate. ----updates soon

The big Radiator arrived today, 7/3/06

I had to remove the old std radiator braces, and the front relay holders,due to the size of this  Radiator.
