Hey Callum, if you don't mind I'm going to eavesdrop on your thread. My car is doing the Exact same thing only mine is a 1999 Eclipse GST. I think it's amazing we have the same problem and two completely different ecus. I just downloaded EvoScan last night and found a logging cable. Going to...

Car is a 1999 gst and has been running great for a while. About a month ago it threw a fit while I was driving it and wanted to cut fuel while under 30mph. I took it home, keeping my foot on the gas the whole time during stops to keep a 14.x:1 afr on the wideband, and started in on the normal...

I browsed around a bit first, sent emails to our sponsors and even caught some on Facebook messenger for live chat, but so far I haven't had my question answered. I have plans on rebuilding a 1990 6 bolt from a manual awd talon and placing it into my 1999 GST which is a fwd auto. The rebuilt...

I thought about Link, but being I already have a '99 gst auto, it means that ecu isn't a candidate to even be chipped. I also have a '95 gsx ecu, but it's for a manual trans, I want to keep the auto. I haven't even looked to see if the 95 ecu is eprom or not. Using Link would require me to find...

Nobody I know has ever tuned a turbo motor, let alone a dsm. Tuning is going to be a learning curve, but the more I research about it, the less scary it seems. Will probably play with the 2g a bit first while the 6 bolt is being built, get comfortable, then do the swap. Thinking of getting...

Back to my original post though. Anyone have anything else to add on 9.1:1 vs 8.5:1 compression ratios? I still haven't received any email replies from the handful I sent out, unless you count the delivery failure to Boostin.

Tell me about it. I've been sold industrial spark plugs because they said Mitsubishi on them, promptly switched my terminology to include NGK. At another place I had to spell Mitsubishi for them. Hurray rural farming communities.

That phrase, "someone unknown that you don't trust" scares the ever-living daylights out of me. Glad I have gear heads and grease monkeys for family. So far my eclipse has been a learning experience for everyone since they're mostly into American muscle.

My only problem is that I want to do the build myself. I understand I can't do Everything, but I'm not about to mail off my motor. I'd rather buy it piece by piece and go from there, call a machine shop for something special once in a while but not for the whole thing. Coming from a family of...

As an added note I looked up what exactly the airport had on hand, it's 100LL AvGas. (There was a chart there probably from a past date I saw with the two other choices.) The 100LL is rated as having a lean automotive octane of 100 and a rich aviation octane of 130 and is currently $4.80/gal.

I'd prefer to stay on 91 octane since it's readily available here. We have one pump in town with E85, but they jack the price accordingly. However, I did get permission from the city to purchase aviation fuel from our airport (choice of 146 or 162 octane). Plus I'm still waiting for a call back...

I'm preparing to rebuild a 6 bolt and use it inside my 2g. So far the setups on Jackson Auto Machine are what I'm aiming for, the Stage 2 motor and Stage 3 head setups in particular. My only question left (so far after loads of research) is in regards to the differences of 8.5:1 and 9.1:1...

Think we're going with 1g head and block. Did some snooping on other builds & like seeing lots of them keeping the stock crank for high hp setups. I'm a little torn between the compression rate goal though. If stock 1g is 7.8 and stock 2g is 8.5, but the most common rebuilt is 9.1, I'm not 100%...

Is there a strategy between using 1g or 2g head? Other than the need to modify the holes on the 2g head to match the 1g block.

Planning on stopping around the 550hp mark, but probably still leave some wiggle room so we aren't stressing anything at that point. And we have a 99 2g.
