my 0-60 time was 6.5 secounds doesnt sound even close what the car should be doing my ...car is bone stock no mods or anything what should i do to get it to run faster with some easy mods? car has 50,000miles
 
It’s really a rough estimate, no traction issues, my buddy and found an old country road to run the time “stop watch” ..the car never really felt as fast as it should be.
 
If it is running properly and your boost is building properly it should be faster than that. I guess you have stock boost lines.

When I got my car the stock lines were not hooked up, it only had 1 hose running from turbo to wastegate, thus bypassing the wastegate selinoid. With this I was only getting 10lbs of boost.
 
The stock gauge reads around 16psi.. but I hear the stock gauges maybe inaccurate.. at times the car feel kinda sluggish I know it has more potential..
 
Probably detonation...

Have you done a spring cleaning? Fuel pump is probably weak, stock chip has too much timing, exhaust leaks...

Do you have a scanmaster?

And are you in Wylie Texas?
 
i have not done any spring cleaning..no scanmaster..i need to check for an exaust leak..first thing i did was change the oil..other than that diff and tranny fliuds may need to be changed.. i do live wylie,tx
 
Where should I invest my money on chips and aftermarket parts? Or replace old vacuum lines, filters , O2 sensor, fuel pump to get it back in shape?
 
Chip, 60 pound injectors and scanmaster from TurboTweak Home

Walbro 340 with hotwire kit from Racetronix.com

Replace all the old vacuum hoses with just vacuum hose from an autoparts store.

Denso 234-1001 02 sensor.

New plugs---pick your poison.

New fuel filter from autoparts store.

And go from there.
 
Is the Denso a better O2 sensor? I just went to the parts store and bought a Bosh O2 sensor also picked up royal purple oil for the diff and engine..should i bypass any vacuum hoses around the wastgate or keep them the same?

Bosch is fine.

Don't run Royal Purple. Go get cheap dino oil (Castrol, Quaker, Pennzoil, ect.) and buy Amazon.com: ZDDPPlus ZDDP Engine Oil Additive Zinc Phosphorus 4oz.: Automotive

Run one bottle of ZDDP with every oil change. If you run synthetic without the phosphorus and zinc your cam will hate you.

Run your hoses like stock for now.
 
how many pounds are the stock injectors? what kinda mods am i going to have to do after i put on 60 pound injectors?

sorry to ask so many questions, I just got this car a few weaks ago the car had been sitting in a storage for awhile this is my first turbo car I've ever owned so you may hear some more rookie questions lol..
 
Don't hold me to this, but I think stock injectors are 28lb.
As said above, get a chip to match the injectors/fuel pump/turbo/transmission/IC/ alky-or no alky....etc.

Here's the thing, I know it's tempting to say "that was fast...but I wanna go faster", and start buying injectors, chips, fuel pumps, etc...but you NEED a scantool, a scanmaster is good to have. And you NEED to do spring cleaning, here's a link to gnttype.org describing the spring cleaning for this particular engine: The Grand National / T-Type / Turbo Regal Buick Spring Cleaning Guide
Set the TPS, set the fuel pressure (I think it's 43 psi with the vac line disconnected), check ALL the vacuum lines going to/from the vacuum block which is the little black box on top of the plenum, if they're old and cracking, replace them FIRST. If the intake pipe from the filter to the turbo is the stock part, inspect it for rips/tears/holes. Remove the Inner-cooler and clean it, go to Lowe's or Home Depot or a paint store and get lacquer thinner, dump a little in, slosh it around, repeat until you're out of thinner, then do the same with water a few times, then use the hose to wash the fins on the front and back, then prop it with the opening down to let it drain out and dry out.

I'm not sure what I missed, but someone else will pick me up if I left anything out. The point is, we've all been there, these cars are a blast, but don't get tunnel vision, ensure it runs properly before modding otherwise you'll be bangin your head off a wall later when you can't figure out an issue..or even worse, when you break something because you didn't have a scantool.

Here's another great link, gnttype.org has a lot of useful info, read it over: General Maintenance and Up Keep
 
What he said - make sure it is running right first. My car is totally stock, and it does not 'feel slow'. But it is running good. My guess is there are issues that are not letting the car run right. With that said, there are members here who swapped to a larger injector and felt a world of difference, but I suspect they probably had clogged injectors, and the car wouldn't run right.
 
Good advice on the spring cleaning..I'll start with the basics before i move up to the performanc ...with that being said 60 pound injectors seem like a big injector or is that compatible with a stock car? I was thinking about replacing them with the stock ones but if I have the chance to upgrade I will..

Agreed. The car is 22 years old. The fuel system needs to be changed out.

The injectors are drop in with the chip. No issues at all.

Buy the 60's. You won't be able to tell a difference.
 
The 60's seem big in comparison to the stock (28 or 33lbs) injectors, but TurboTweak creates a program that runs the big injector's duty cycle and pulse widths within the parameters that your specific engine combo will demand.
I'm guessing that your set-up is stock, you could probably run a set of 42lbs injectors (also sold on TurboTweaks web-site) and it would be a great improvement. The 42's would basically would be running at closer to their maximum capacity, where as the 60's would easily provide you with "room to grow".

What you need to ask yourself is how far do you want to go with your engine combo. His site has the 42.'s that are a little cheaper than the 60's which it says are currently out of stock. For reference, I ran a TE-44 turbo and 42's to 12.10's in the 1/4 on a 2.0 60ft. But I've since got the 60's and matching chip. Haven't ran the car yet, but I can testify that driveability and idle are as smooth or smoother than the stock injectors and chip.

I've tried stock, 42, 60, and 80 and I have to say that the 60's are great!!! Id get those as my first choice for just about any tta build level.
 
I went from stock injectors to the 60's, make sure you get a chip matchflowed for your setup.

Along with the injectors and chip I went with a larger turbo and with a Alky kit from Razor. Plus I did all the spring cleaning techniques listed above.

I had my motor out recently and replaced everything that needed replacing such as motor mounts, rear main seal, etc.

It is running great and I am glad I went as far as I did with the servicing.


I am really surprised how smooth it idles with the injector and chip combo.

The least you should run should be 93 octane.

Alky is alcohol injection, did a lot of research on this and talked to alot of engine builders. It is highly suggested to use Alky, because todays gasoline is not that good even the 93 octane. The Alky will greatly improve your octane and will help to keep the knock down in the engine, under boost conditions.

I blew headgaskets on 93 octane before I started using Alky. It also keeps the engine cooler with the alcohol.

I would not run another turbo motor without using Alky.:thumbup:
