OBD1 or 2?
Do you want to do in-depth stuff on OBD2 GM specific stuff where you can do crank learns or see ABS pulse data or Tcase stuff or just generic code reading.
What makes the ride rough, is it too low and you hit the bump stops too often? Is the spring rate too high?
You could look at swapping to a ZQ8 s10 foam bump stop instead of the OEM rubber one. It makes hitting the bump stop a MUCH less firm experience. For $25 and 10 minutes I'd recommend...
For what it's worth-
A non adjustable Bilstein is getting awfully close in cost to a single adjustable Strange stock (IMO). Unless you are in some autocross class where adjustable shocks aren't allowed, if you care about rebound why not go adjustable?
A set of Bilstein is like $200
A set of...
Dad swapped all the RWD stuff from the 'hot' l67 to this 'lame' stocker l67. New intake manifold gaskets and that's it. Heads never came off, just swap the intake manifold and oil pan and half the accessories that are different.
The S2X cam did not survive (some nicks from the meat grinder...
If you have to ask, I'd start with a complete running car-
Make sure the steering and brakes work, the doors close, windows roll up, blinkers work, title matches the VIN....
Rollers are often basket cases. What was taken out of the car when the previous owner pulled the engine? What was...
Do you have the facebooks?
Join the '2004r nerds' page. I'm sure there's an answer there.
Cruz performance is in Tampa, probably could call him and see who he uses or could recommend. Most 2004r shops are turbo buick specialists.
First things first, make sure your steering system is in good shape and no wear.
As far as control arms, since you are looking for improved handling, you want something that gives you a better camber curve (taller ball joints) and more caster (upper control arm point moved back at minimum...
Upper or lower control arms? Both?
What are your goals with the car?
I guess what's wrong with the stock ones. Do you just want them to look tubular? Do you want to save weight? Do you want better geometry for handling? Do you want to run coilovers and need a different bracket to mount the...
My other assessment
If you want to make over 550hp, get a 4l80e
If you have a Chevy engine with a ECU or carb that cant do e-trans control, get a 4l80e with an external controller
If you have EFI that has electronic trans control capability with a BOP, get a 4l80e
The only case I see where a...
I am by no means a guru and mostly did this video series for myself to remember what/how I did it, but if you are interested in doing it yourself there are 4 videos in my series you can peruse. Most 2004r rebuilds seemed to be more doing the work vs. explaining why or how so I focused a bit more...
I rebuilt my 2004r last year without a single special tool. All I did was grind a notch in a screwdriver and use normal hand tools and a yoke to hold and center the output shaft.
I went through Dave Husek out of NYC for my parts (Turbo buick performance). Pricey but everything is in stock and...
It comes apart. I replaced my bulkhead in my GN hanger so I could run a Wally 525 pump with that racetronix one. The stock passthrough was designed for like a 200lph pump and if you have twins or a big single it's going to be too small.
Heres a quick video I did-
I have a 6062 VSR T4 and gate, some 3" bends for a downpipe and some treadstone endtanks for an intercooler on the shelf. All I need to buy is some charge pipe and the actual intercooler core (along with some TIG filler and gas) and I have a good path forward to un-cork the exhaust side of this...
Oh and every time I go on a drag weekend and see stuff running deep 8's my brain starts thinking.
This simple dimple LC9 4th gen with a 91mm was running 8.1's. Dad said he would sell me back the 99 firebird. I've got a th400 and 285k lm4 sitting between the fenders of a Rainier 😂
Drag weekend #7 for me is done and car still runs great. About 18 1/4 mile passes and I think everyone was clean. Trans and chassis worked great which helped. I didn't spin a single launch (granted I am only running high 1.7 60ft times) but no wheel hop or drama. Trip was 500 miles so great test...
Data is always cool. Shows how much refinement there is between a 9.99 car and a 8.99 car even with generally the 'same' setup
Interesting the big treadstone IC is the restriction.
Got any more drag and drives planned for the next year or still settling in from DW?
It should work however the amount the pickup point is raised I am almost 100% sure will hit the trunk floor at full bump stop.
I did something similar for my 8.5 in both my 2+2 and cutlass. Bought a S10 zr2 rear thats an 8.5 and use the cover bolts to hold a bracket that looks similar and give...
Calipers and new master showed up Friday
Got the calipers on, replaced the factory 3/4" master with a 1" 82ish Riviera disk/disk master and bolted it up.
I had to put a small radius/chamfer on the outside of the cooling fin on the caliper to provide clearance to the wheel but otherwise just a...
