Ok, I think this is my last question on the 91 GT... for now anyway . The clutch is really soft. I may just be used to my 87 Sundance Turbo which was set to be REALLY stiff and you didn't have to push it in much to disengage. I seem to recall my old 89 gt being this way too, but wanted to double check. When I pop it, the tires spin and I dont feel it slipping, so I think it's OK, but is it normal for the pedal to be this soft and the clutch to be set so it doesn't disengage until about 1/2 way down? Also, I wanted to know if this 1.8L Mazda engine is or is not an interference engine. I am going to replace the timing belt, but thought it was a good thing to know. Thanks in advance.
Thanks, that eases my mind about the clutch, but are you sure about the engine being interference? I know the 1.9 Cosworth is supposed to be interference, but I read that the 1.8 DOHC Mazda is not interference on several occasions, and now a couple of people told me it is... which is correct?
Theyre not the same engine though. There's the generation 1 High Output GT engine, and what I think was a 1.8 or maybe a 1.9L regular scort engine. In 1991, the regular scort got a 1.9L Cosworth, but the GTs took a 1.8 DOHC Mazda engine (the same found in the 90 protoge and I think 323 and/or 626s). This is a completely different engine, and the only reason I purchased this car. I loved my 89GT, but I don't trust american made engines to run for high milages without major repair. I got lucky with the 89, and the death of it was cause by the ingnition modulator. I trust Mazda engines to run forever, and really want this 91 GT scort to be my everyday car for another 100,000+ miles. I am just trying to clarify the differing answers I've gotten. I've been told the 1.9L cosworth is an interference and the 1.8 mazda isn't. I've been told that the mazda is and the cosworth isn't. Now you said they both are. I just want to know for sure, and can't find any answers from the manual, repair manuals, dealerships, mechanics or messageboards.
N, it is a Ford Cosworth engine. The Mazda engine was introduced in 1991 with the overhaul of the Escort. 191 marked the 1st year of their 2nd generation. The regular second generation escorts have a revamped cosworth 1.9l 80 something horsepower engine. The second generation GT has a 1.8l Mazda engine with (I believe) 187 horsepower. This is why I wanted to know the difference as far as interference/non interference.
This is just food for thought but Escorts go back in the '60's. In the '70's the UK Ford company offered the US an option to bring the little beauties to the states not very many of them were sold because of a low demand, it only lasted like 2 years. So Chronologically we have a 4th generation and your '91 is probably the 5th gen., but in the US their considered the 1st and 2nd. I had no idea that they used Cosworth engines in US models.
I thought all ford engines were cosworth, and if not I am pretty sure the 91 (& corresponding generational years to follow) 1.9L is cosworth. I could be wrong though, but Im certain the 1.9L is a completely different engine than the 1.8L. The 1.9 is American and the 1.8 is Japanese (mazda). The 1.8 has a lot more horsepower, and has 2 cams. The british escorts are far different. Even when they were being sold in both countries, they were different... the british was much better... more like a GT model. Also, food for thought. The Escort discontinued in production a few years back, and the Focus became it's replacement, and although similar they are not the same... however it seems that the ZX models are a continuation of the GT line without the Escort brand.
