Hi, I have just stumbled upon this board and it looks like the oasis. I have an 87 Regal Limited with the "T" package. I ordered it new and made one serious goof. I assumed the "T" package included the limited slip diff rear end. I got the 50,000 mile extended warranty. At about 47k I was having fuel delivery problems. The Buick guys replaced pretty much my entire fuel system and tuned the car up to the max and it ran good for a month. Kind of just drove the car to 127k and parked it. I still have always started it and it still runs.
Now it is in the shop. I am doing the underneath and the fuel system is first on the list. I want to do the Park Ave Ultra fuel pump/Somerset "237" fuel regulator upgrade. I am replacing the fuel lines and I have an opportunity to upgrade when I replace the injectors.
So my first Q? is: Is this a sensible fuel delivery upgrade to solve the original fuel delivery problem on the stock injectors and get the max out of that setup.
2:Can the ParkAve/Somerset fuel setup be optimized with larger injectors and really benefit from the ram air and chip from ART that I have. (they are a good 6-8 years old)
3: Any ideas if you were "slightly" modifying your 87tr to more-or-less kill any Mustang or uppity little squid in a rice burner. Is it feasible to put out maybe 400hp or so without getting too crazy or what am I really talking with the Buick parts fuel delivery? (I will get a posi or limited slip rear end, but that is later, once it purrrrs. The engine needs opened up to get rid of the stupid leaky main seals and have the pistons gone over because of the high mileage so it could be bored out or ported or whatever other open engine options I will have. I drove it pretty easy all-in-all because WOT was not an option for most of it's life, doesn't that suck?)
thank you all for your help. Hopefully next spring, I'll be standin' tall with the rest of you guys doing my part out on the highways...heh heh
First of all that fuel upgrade u are talking about sounds like a pain it the ass, your fuel lines should be fine but if u look around the upgrades everyone is doing is a good fuel pump walbro 307 or 340 (there is a zillion different kinds out there) any one described on this site should be fine, precision turbo and engine currently has a 307 for 92.00. Next a hotwire kit for the pump,(you can do this yourself for cheaper than u can buy the kit for) a adjustable fuel press reg is a must for tuning, and finally your injectors should go hand in hand with your new chip, and your final turbo size will also play a major part in choosing all of these parts. Call any of the major vendors on this site and they will be able to match all of these parts properly for u so u dont waste your money and u will be laying 10ft of rubber in second gear in no time, so dont make any quick decisions till u talk to someone who knows what they are doing! before you call u need to sit down and decide how fast u want to go and they will take it from there, as far as your rebuild for a eng that has 127k and wasn't beat there is a good possibility internally it may need much of nothing, do a compression ck, if all is good and oil press is good, change your timing chain to a good double roller, change your valve springs to upgraded units (these are both cheap parts) and listen to your vendor recommendations, a rebuild can benefit any eng but my stand point is spend the money where it counts if you dont have a large pile of it to waste...good luck
Good advice from Nick...
Here's some specific "Recipes" to help you get where you want to go. Pay particular attention to the Hot 'n Spicy Turbo Regal Recipe, since it concentrates on a low buck way to get mid 12s with no compromises.

As Nick said, I wouldn't waste time with the ultra pump and such. Just get one of the vendors kits with a Walbro and a hot wire, and it should get you where you want to go. It's amazing how many high mileage cars are pounding out 12s without any major internal engine work.
If you do decide to do some rebuilding... lots of good tips in the Technical articles section (URL above and you can get there from the pulldowns at the top and bottom of the web page.
OK, I have someplace to start! See, I was screwing up already. If I understand your guys' advice correctly, the trick is to look over the total package based upon the performance level I decide upon, THEN select the package of tweaks.
I am going to pour through the archives and info in those links to minimize my stupid questions.
So, thank you for your replies, I'll check back in after I've done some homework and am starting to get a real idea of what I want to do.
No stupid questions ... we all have had a learning curve with these cars. I ordered mine from the factory, and I *STILL* learn new stuff all the time from the great folks who participate in the list!
Basically, my rant is exactly what you are saying. Look at your goals and the car as a system. Pick the combination to acheive the goal and with all the parts optimized to work together. Then tune, tune, tune ....
Altho' I do believe in stupid questions,
, yours is certainly not anywhere close. These cars are all about combination. All to often we see posts where someone has literally spent thousands and are running in the mid 13s and sometimes slower. Reading the links that Ken has provided will keep you from doing this and should have you running well without major expenditures if you will do the work yourself.
Don't believe in magic. Believe in combination and believe in the foundation that the original GM guys provided you to work from. They hid a 12 second car in every package!
thanks again. ....still researching, just checking in(getting really psyched up too, seeing all the toys and services, wowie!).....
and a place to get those GM shop manuals
(I was bad, for my '91 Park, I signed them out of the library and then said I dropped them into the oil and paid them whatever $110 bucks to replace the manuals (yeah 2, one huge one just for the electrical). I gotta admit, that was handy.)
