If you're asking for a bolt on turbo upgrade, it's going to be harder to find.
You can check on ebay, a lot of people machine out the compressor housing of the stock 12A and fit in various other mitsubishi compressor wheels. Some people even upgrade the compressor housing too. Mitsu turbos are fairly straight forward to C-clamp off and mix and match, as long as you get 'em balanced when you're done.
DSM-14B turbos may still be easy enough to find, but the one you're likely going to want is the evo3 16g.
Another minor note, aside from clocking the housing and getting the pipes to fit, you may have to make a minor mod to the downpipe flange.
Stock starquests have the stock downpipe without wastegate hole. (1 hole)
DSM's and evos use the diamond style ones with two holes: https://www.ebay.com/itm/133818987037?hash=item1f283bb21d:g:AbkAAOSwXyla9H-b
Another note, the evo8 and newer use different turbos. Even though they are named similarly, there's an important distinction.
TD05HR-16G is not hte same as TD05H-16G . The R stands for reverse rotation, i learned this the hard way
A lot of people will hate on the alternate idea, but now a days the "terrible crappy chinese ebay turbos" are not as bad as they used to be. I haven't used one on a starquest, but have on other cars. A bunch of friends use them and have had great results and for a bargain. You can't even get a damaged/used turbo for under 200 bucks, but you can get one from china to your door. https://www.ebay.com/itm/294331324222?_trkparms=ispr%3D1&hash=item448783973e:g:6EAAAOSw8k5hV712
- if you do go this route, make sure you use a restrictor fitting on the oil feed line, as not doing this is the main reason people report their chinese turbos failing. https://www.ebay.com/itm/154454145215
The turbo ebay link is for a 20g I think. You said look for a TD05H-16G right? Will any TD05H-16G work on ebay? Also will I need another downpipe to work with the diamond plate? Thanks for the info and links.

Can anyone tell me a good bolt on Turbo upgrade for the 1987 starion and where to get it? It has the original turbo on it. Just looking for a little more HP without any modifications. Any links or phone numbers will be appreciated. Thanks
-
ok. I thought it might be a drain. Is it ok to let it hang there at the bottom or do I need to try to find that nipple? Thanks
-
Can someone tell me if the very bottom MAF hose gets connected to anything. If so can you tell me or show some pics of where it goes? thanks

I will probably send my secondary injector in to get cleaned.
3500 RPM you say..... do you know your 2nd injector is good? IIRC that is where the 2nd injector starts to fire.
-
I will check to see if its sticking.diss sticking ??
-
found a forum and they recommeded the vacuum advance. I bought a new one and replaced it and it still cuts out around the 3500 rpm (arounf 3 boost area). I still have to clean the distributor...
Could it be the timing?
-
Yeah that's weird. I've seen it tuning before as you can get into a spot where the fuel and ignition moving up and down creates a cycle like that but I can't fathom the factory setup doing it. Having said that I'd give your distributor an overhaul to get the old sticky grease out of there and replace the injector clips.
I already replaces the injector clips to.

Try a TPS/ISC reset.
Thanks for the info

I will get a new distributor and try that.

My 87 has this revving problem almost everyday for about 5 minutes or so. Then it goes back to ideling and running ok. This video is what its doing.

ok thanks for your help
-
does it need to be connected?

as stated before, if the clips don't fix the issue then send the injectors off to be cleaned. Hurst Injector Service is a great place. awesome guy, very good pricing, top notch work, and very quick turnaround. hurstinjectorservice.com. Even if the injectors turn up being fine it's still not a bad thing to have done for reassurance. I mean it's only $35 after payment and the small shipping fee.

I will change the fuel filter this weekend and if that does not help...I will probably contact hurst....Thanks again

recent...about 1 month. Another symptom is driving it and losing total power for about 1 sec then it kicks back in and then does it again with 1 sec intervals for about 20-30 secs....How long had this been going on? Just recent or what?
-
Update..drained all the fluid and replaced with new fluid and fixed the problem. Thanks for your replies.
-
they are stock injectors....put the new clips on and its still sputtering...what else can I check?Stock injectors or aftermarket?
-
I replaced the clips with new ones but the car is sputtering when I stomp on it....what else can I check?Wideband is a Air/Fuel Ratio (AFR) sensor that tells you how rich or lean you are. As suggested above, since you don't have a wideband to check your leanness/richness, check the wiring and secondary injector. Have you replaced your injector clips or are they original? You can buy them from Dad.

ok...thanksgo to eBay and type "301015353672" into the search bar.

What is the link for the clips? Thanks for the info.it's hard to clean them yourself. there's a way you run a strong mixture through them and pressurized and pulse them using a 9v. but it's worth just sending them off to be cleaned. check out Hurst Injector Service. I had him do mine and the guy was AWESOME. I think I paid like $32 and he kept in touch the entire time to give me updates on the progress and he's really easy to deal with. I know he's cheaper than most and he does top notch work.
as for clips, I don't mean to take business from locals and guys here on the forum that serve us well, but I got some EV1 quick disconnects from eBay from the states and they're great quality, they clip and seal well, and it was only $10 for 4 clips with pigtails. it's up to you. I can provide the link for the clips I got if you decide to go eBay route. for the record...Randy sells great products and is a great guy and I support him entirely.
