New products in the pipeline

Plus4E venture into Porsche tooling!

Plus4E are pleased to be able to add Porsche tooling to our repertoire of products. First up are 24mm and 27mm spanners based on the original 9244 spanner. The design of the spanner allows accurate adjustment of the balance belt idler pulley and the tensioner pulley on all the 944/968 range of engines.

Currently listing on ebay, and will be in our own Plus4E store very soon.

1UZ / 3UZ Thermostat housings

Our thermostat housings are in development, and we expect to have completed items available by Christmas. wp-1449733426012.jpeg

One of the issues with a Lexus V8 conversion is that the outlet from the thermostat points in a specific direction – less than ideal if the hose on your radiator is on the other side!

wp-1449733543943.jpegInstead of complicated routing of hoses and couplers, use one of our thermostat housings, which presents a forward facing large bore swaged aluminium pipe, and use a silicone reducer elbow of your choice to route it in the direction that suits your installation best.

Check back for updates as these develop!

1UZ / 3UZ Oil Filter Adapter Relocation kits

Excited to be able to announce that we are very close to launching our oil filter adapter kits for Lexus V8s. Made from 5083 marine grade aluminium, these are designed by Plus Four Engineering and manufactured in the UK.wp-1449738010538.jpeg

You’ll get your choice of parts – just a plate? No problem. Need a filter relocation point? We have that covered. Hoses? Yes, we can include these.


As ever – looking to be flexible to your needs, and keeping engine conversions as simple as possible on a budget.
