Cosworth is King
Just thought I'd ask the question, anyone used the Cosworth YB engine for an engine conversion. Here in europe when we talk about cheap performance Cosworth is always first on the list. Ford dominate all european motorsport in the 80's early 90's with the 2litre cosworth YB. 400Bhp is easy.
Here is what Wiki say.
This unit would easily fit any of the Rx7 engine bays, with stoking performance. Just wanted to give all you guys something else to think about. Plus I would say it's never been done so unique to say the least.
Here is what Wiki say.
The YB series of 1,993 cc (121.6 cu in) engines are based on the older Pinto engine block and were introduced in the road-going Ford Sierra Cosworth in 1986 with 204 bhp (152 kW). It was the first road going engine that developed more than 100 bhp (75 kW) per litre, with 5,000 units built for homologation purposes in Group A, both for rallies and touring cars. Racing versions could develop about 400 bhp (300 kW). A limited edition evolution model was introduced in 1987, the RS500, with power now exceeding 550 bhp (410 kW) in full racing trim. The RS500 came to dominate touring car racing in its heyday. Today there are many road going YB engines developing over 800 bhp (600 kW) and there are several rallycross Sierra Cosworths utilising YB engines tuned to over 900 bhp (670 kW). The Rev Hard drag racing team use a YB engine in their Escort Cosworth car that develops 1,100 bhp (820 kW) whilst still retaining the original 2 litre capacity.

...seeing as they were never produced in America; that throws the 'cheap' in cheap performance out the window for most of us. Otherwise I'd be interested; going with the lima instead, as it's easily found in junkyards around here in the states...
