Chris Davey wrote on Mon, 09 August 2004 12:13 | well there is a good question.
has anybody blown a headgasket on a 7m AFTER they have gotten a new one that has been retorqued properly. is it 72ft/lbs? I thought I read that somewhere? anyway I don't have a 7m
can we just say that both engines have their strengths and weaknesses?
I would like to see the stock ma70 vs jza70 race though
|
A few of the Seppos seem to still have problems even after the retorque. But there are a number of things that can help it along too.. I never had a problem with the HG on my 7M when I had it once it was retorqued. It finally expired with bearing knock at 265,000kms But they are an old engine with old roots dating back to the 50s with development for the 2000GT. The JZ engine is better all round and you only need to drive one.
Stock for Stock the JZA70 is 1 sec faster than the MA70. It's been tested over and over in Magazines and also the specs for the Cars from Toyota. The 7M is a good engine, it's a good workhorse but you can't really push it much more without ALOT of re-engineering due to the motor itself being a pushed 2M from the 60s.
You can't argue with Evolution guys. Build a bridge and welcome to the 21st Century.
