*sorry the post is kind of long, but please read it, please!*
Well, I'm new to this forum, but i've been to the celicasupra site many times in the past - what a great resource.
In any case, it's taken a few months, but my buddy and I have finally settled on purchasing an '82 Supra L-type for our first rally car. Ignoring its practicality as a rally car and anything to do with what we're doing with the car, I have a few comments and questions.
To start, the engine is not stock. It's also not running, but that's besides the point. We can get it running via push-starting, so I'm willing to bet the starter is gone. However, what's under the hood when it finally does run is what's causing me some concern.
important things are bolded...
Without knowing specific specifics, the engine has been bored out to 3.0L (6m spec? I don't know, help please), the head has been ported and polished (how much power gain there?), the exhaust header is completely custom built (looks good, I believe it's a 6-3-1, but don't quote me), and there's a 2.5" (or maybe 3") straightpipe all the way to a very weird looking muffler (which i think has nothing inside of it). Also, it has a cone-filter intake thrown in for good measure.
From what I've read here, and at other websites (toysport, for one), I'm very confused. The person we're buying it off of stated that teh previous owner (the one who did the work) dyno'd the car at 200hp to the wheels; however, there is no sheets to prove this.
My question is: how much power do you really think this thing would pump out? I've seen some stats that say the 6M was a 3L, and that it had 190hp, but have also seen stats that say a 2.9 and 3.1 overbore on the 5M produce 220 and 240hp respectively. I'm just not sure what to believe.
In addition to this, service records for the car show that the car experiences "excessive valve clearance" and "blowby" causing oil-burning at high rpm. My questions on other forums have given me mixed reactions to this. The general consensus is that the blowby results from the engine not being properly broken in after being rebuilt 3 years ago (ie. the rings didn't get enough time to seat properly). The excessive valve clearance results from, we think, the fact that the head was planed, and thus the valves go deeper into the block when active.
So basically I'm asking for help in two areas: how much power am i making, and how severe are these problems that the engine has?
