Default Upgrades/mods

So...I just bought my first newer car. Going from 2 fieros to....a 2000 boneville ssei. Only has 36k miles on it and am wondering what kinda mods i should put on it and what kind of increase/cost I will be handed. One of my better friends owns a 98 GTP so he'* given me a few mod ideas that he did on his 3800. Suggestions/help would be greatly appreciated

Thanks!

Hey, cool, I can say this first.

As everyone will say:

1.) 180 Stat
2.) Trans Cooler
3.) ADTR Intake (custom for our cars)
4.) High flow CAT, performance muffler, headers
5.) SC Pulley
6.) Superchip
7.) Go nuts from there.

Those listed will give a huge jump in power, but it will definitly cost a couple grand.

Not bad, Sol, not bad at all. You covered it well.

Welcome to the Forum, Badboy! We'll have fun watching you spend money for speed!

I would add to that list:

1) A good set of plugs
2) A good set of plug wires
3) Aftermarket coil packs

I've done all three to my '95 SSEi and the difference in power and throttle response was easily noticeable.


The good news is that alot (not all) of what will fit your buddies GTP will also fit your SSEi as well. You can watch what your friend does and get some good ideas from him as well. You can also do some looking at the only two places that sell specifically to the Bonneville market which are Domestic Performance and Angry Duck Tofu Racing. If they don't have, or can't get, what your looking for, you can also check out the Grandprix stores as well.

Not so fast, guys...you are listing good mods for the engine, but you are forgetting some other, very important safety/performance mods:

RSM Slotted rotors (Domestic Performance carries these)
Ceramic brake pads
Thrasher Shift Kit for the 4T65E HD transmission
A GOOD set of performance tires.

After doing all the work on the engine, you will want to slow that Bonnie down without warping your rotors. With all that extra hp and tq, you will also want to take care of that tranny. Although an auxilary tranny cooler was mentioned, it would also be advisable to install a shift kit. The shift kit will lengthen the life of your clutch-pack and give you firmer shifts. Too bad they don't make a shift kit for my 4T60E HD transmission.

Because the 4t60-e is not all electronic domestic performance uses a modified modulator (minor change) and the blueprinting (big change) and valve changing (another big change) to get the shift firmer. The 4t60-e is not as cheap once rebuilt but it is a stronger unit to begin with and the system is actually very solid.

Also we now can get you your rotors much faster.

So there is a shift kit available for the 4t60-e? How about the 4t60-e HD? I would be interested if the price was right.

Nope there is no set "kit" basically when we blueprint your transaxle we can set it up to have firmer shifts. You can get a $60.00 modulator if you want but it will not make a big difference. The big change happens with better valves with a performance blueprint. My new-revised 4t60-e/HD price on the site is higher than I will charge any Bonneville club or Bonneville attitude members. All our 4t60-e transaxles are beefed up 4t60-e HD units. If you want more info look on the site or call me directly at 559-709-4127,ask for Ty
