2nd GEN. BASIC KIT (2004-R)
Pictured above is the Basic kit for the 2nd gen RX-7 / Chevy V-8. The Engine Cradle, the larger welded steel structure,
fits between the stock RX-7 front sub-frame, and the Chevy engine's rubber side mounts. The "Spuds" (the tall aluminum machined
spacers pictured) drop into existing holes in the subframe, located just in back of the steering rack (the holes were used by
the factory as locators when they welded the two halves of the subframe together), and provide a solid anchor point for the cradle
while preventing collapse of the hollow crossmember as the bolts are tightened. Another anchor point is used in the center, and
the "Struts" extending rearward from the cradle tie into the subframe at the area that was formerly used to anchor the rotary
engine, providing further triangulation. While the transmission crossmember shown is of the "truss" style (necessary because
of the extreme rearward location of some Chevy trans mount pads), the T-350 and manual T-5 5spd use a crossmember that bolts
directly to the RX-7 chassis at the existing points used for the rotary transmission crossmember.
A 2nd gen V-8 cradle in it's installed position behind the steering rack.

...frequently asked questions....
...What engines can I use?
Most any 90 degree Chevy V-6 will work. The carbureted models make for an easier conversion, but TBI (throttle body injected) engines can be used.
...Will the Chevy V-6 fit under my hood?
Yes, with the proper attention to intake manifold and air cleaner selection. Stock type manifolds that have an EGR valve will not fit w/o hood modification.
The shorter non-EGR manifolds and 4bbl carbs require a drop base air cleaner, and may require trimming out the inner hood brace in the area of the air cleaner, but will fit under the hood.
...Can I use my stock RX-7 radiator?
Yes. Many customers are using the short V-8 water pump in conjunction with the stock RX-7 radiator, fan, and shroud.
...Are there any special requirememts?
Because of the high cost of aftermarket distributors for the 90 degree V-6, we offer special kits that allow for use of the larger dia. HEI as well. The larger dia. "HEI" units require the "HEI" style Basic Kit, which positions the engine 3/4" farther forward than the STD. V-6 position.
A "short" V-8 water pump (pre-'68) and pulley set is recommended. Double groove crankshaft and water pump pulleys are required to drive the P/S pump and/or the A/C compressor.
