Luckily I don't need to do a whole lot to bring it back.

As far as what I'm going to do to it you will see soon enough! (nothing spectacular with my budget) but I would really like to figure out a limited slip diff for it...

I should have read up on welding the exhaust manifold on my Starion because we just welded the crack and I'm pretty sure it's warped a bit now. This one though... I've already got a fix for it in the works

It sure as heck looks the same on the trucks so I ordered up a header off of Amazon!

$140 Amazon headers shipped to AK! Not too bad of quality for how cheap they were. I'm sure there will be fitment issues... but remember kids this isn't a JDM Legends build. It's a $200 car.

A whole $67 for the rest of the exhaust. Made it a side outlet so it would be cheaper and easy to make. Fits perfect, a good 2 inch gap from rattling on any part of the car but would rather have a rectangle exhaust tip.

Oh btw do you see the front end parts? The car was in my garage nose to nose with my '87 Starion and while rolling around on the ground it looks like exactly the same front end components. Even the the same front brake intake plates.

Started the thing up and shoot dang it ran! Now that there are no honeycomb webs stuffed in the exhaust it had a louder tone. Still a nice quite rumble at idle and the Turbo Thrush muffler has a decent revving sound. Not fart can-y at all. But the best part of all was that after letting it warm up and get off choke it revved up quick. Runs great. Took it for a nice little spin out on the semi-ice covered roads and I wouldn't say it has a whole 178hp of turbo power but we're up above the stock 105! One wheel peel in first and up into second gear like crazy. Cruises great.

I'll post some pictures up of cleaning other things up on the car here soon but it's going to hit the back burner soon while the Starion engine gets pulled and rebuilt AGAIN.

While that's happening how about info on getting a limited slip of sorts in this thing and a slightly bigger cam???

the performance-craved/boost junky in me always size up what u pump into normally aspirated modding
vs.... bolting on inexpensive starion bits onto the 54. yielding twice the performance
like this fine truck example here:  http://www.sqperform....php?topic=93.0

montero/raider guys have posted lotsa info on their turbo conversions too.
Some say the 'dinky' TBI before boost, ran & performed better than the 32/36 weber. Wierd
I know its not the goal with this car.... just thinkin out loud

hey, if u inherit some money or win the lotto, u could go crazy, like so: https://www.youtube....h?v=kNZMMA35VII
them wheels tho...  :o

Haha I bought this specifically because it DID NOT have tbi on it. Being a dirt bike guy/ motorcycle technician by day the whole carburetor thing is a cool idea for me. I've already blew up my Starion from trying to make more power and the last thing I ever want to do is is spend money and do an engine swap or dare I say put a TBI turbo setup on this car.

As it sits the car is as good as it needs to be for me to drive it come spring but If I can figure out some axle info about this thing and getting an LSD in it, $100 cam regrind and MAYBE removing the silent shafts like I did on the Starion I'd be happy with the whole 15hp I might gain.

Well I just quick searched the site and there isn't any straight answers. "As everyone wants a factory lsd diff centre, I have recently found 3 lsd centres that will fit the 10 bolt scorpion diff.

My first question to everyone is what are they worth? One was $1550 another $1400?

My second question is, does the turbo sigma GK shape ( 4 door starion) import, can anyone confirm this centre is the same? for scorp 10 bolt.

Also are axles the same?

Depends. Typically a good one will go for around $900- out of the JB Starions (what they consider a small diff)

JB Starion??? uhh i heard through the grapevine the flatty diff will work. what the heck is a JB Starion?

In Australia they go by chassis codes. JB is a mid 80's flatty starion.

Thumbs up on that info.

Been told it might be the intercooled flatty that I need the diff out of? Does the original flatty cars not have an LSD?

Not that I know of. I've always heard only the intercooled cars had LSD's.

I can confirm that narrowbody cars normally didn't come with LSD diffs. The ONLY ones that did were the odd few they made right at the end of 1985. Around here people always refer to them as 85.5 cars.

1987 Flatty Starion -- Widebody Conversion -- V-Mount Setup --  JDL Tubular Manifold  --  MX-6 Intake -- MS3-Pro -- AEM FPR  --  ARP head studs -- 3" hood exit exhaust -- Hahn Racecraft 16g --  Tial F38 Wastegate -- Tial Q Bov -- Short route piping -- 5 lug & LSD conversion -- Tubular Front End -- Manual Steering Rack Conversion -- Manual Brake Conversion -- Stack Digital Dash -- AEM UEGO -- D2 coilovers -- full GNT poly bushings & mounts -- four 8" rears -- car lightened significantly...  More to come!
