I still say the N* is better. Hud still can be used and the swap is not for the regular guy but if you plan on seriously modding your engine like some of the forum members a Bonneville will always be slower than an equal GP..sooo for that reason and many others you will need more power. Yes I pulled the ego punishing GP card.

I mean think about what is required to seriously mod any 3.8l

Pull the engine and the transaxle and rebuild.

Well this is the point that it makes more sense to first modify the n* or 3.8l and then the work left is the mounting of the engine and transaxle. Either way both involve serious work and money. The N* will always win when equally modded.

Never will be a slight mod or cheap fix. I also don’t want people to think that the 3.8 is not a great engine in my opinion. Just that I believe on these points the N* is at least a equal in the option department.

N* options turbo, SC, centrifugal, or Roots. Nitrous.

Head and cam options with up to 100hp gains available.

I couldn't agree more Ty. If your going to rebuild A Northstar it is going to outperform a L67 big time with equal mods/rebuilding. The only problems lay in the cost and no one advertises that it can be done, it takes $$$$ Once there'* more N-star conversion kits out there, we might see some more aftermarket for it. Especially in few years when GM'* performance line of caddy'* will include a V-series in all lines which slaps on a blower to Northstars. Can't wait for that test ride.

Hello people! :?:

I am new here and this is a very interesting topic. If I may add to this topic this point:

A Buick Riviera shares the same chassis as the Aurora. That being said, it would be better to compare the times between an Aurora and a supercharged Riviera of the same here (preferable the newer Rivieras because the first of the 94s and 95s had only 225 hp compared to the later models with came with 240 hp). I think that is a fair comparison to see how the Northstars fair against the supercharged 3.8s. Of course, if you find numbers, it would only reflect 0-60 times and quarter mile times and not so much highway speeds/times.

now that'* a better comparison!!!

You are correct in that regard. However, since 2000, the Bonnevilles share that same platform, so the current bench racing scenario is still valid.

how come everyone thinks there was a 94 riviera and 94 aurora?

both started in 95.

for times, ill add this

aurora w/3.71 ratio 0-60 in 7.7, 15.9

aurora w/3.48 ratio 0-60 in 8.2, 16.1

according to the mags

Eat my Autobahn

It'* me again...

Mikey, You are correct on both counts. The new Bonne does have the same chassis as the 95-99 Aurora and both Rivy'* and Aurora started in 95 (my bad). I guess the better comparison would be to compare the Aurora with '00 Bonne SSEi. Question: what gear ratio does the SSEi come with? 3.48 or 3.71 And the '00 SSEi comes with 17' wheels therefore making it work a little harder to run. So which is the better comparison:

The Rivy and the Classic Aurora

or

The '00 SSEi and Classic Aurora

or better yet:

The '00 SSEi and the '01 Aurora V8

BTW,

I chose the name I have because I currently own a 90 bonne SSE and looking to purchase a 97 Aurora w/ Autobahn package I've been spying....

Pray I get it!!!

There was a 94 Rivera. The Aurora started in 95 or 96. The riviera been out for a long time, then let go in 99 I think.

no 94 riviera. 93 was the last year of the older style, 95 was first for the last style. i know the aurora was supposed to be released in 94, they had them made in 93 and carmags were testing them, but they held off till 94 for a 95 model. perhaps they did the same with the riv, they wanted both to be released at the same time, maybe the riv wasn't done, so they held off on the aurora a little? not sure.

ive got a 95 aurora, they went 95-99, then 2001-2003


i believe the 00 ssei'* had 2.93, with a option of 3.05, the aurora'* NEED 3.71'*, dohc engines don't have a whole lot of torque from the start, not so much of a problem on the ssei'*.

Does anyone know the gearing for the Bonne GXP?


Never mind (It would help to use the web for other purposes besides posting messages on a forum site specific to a vehicle i actually don't own, YET )

Anyway, the ratio for the GXP is 3.71 just as the STS and Autobahn packaged Aurora'*

In essence, you can say that the Aurora lives in the GXP.

Oldsmobile maybe dead, but it'* spirit lives on!

Now only if I can say the same thing about the GTO and the death of the F-bird/Camaro

I hate Ford for what they have done with the new Stang (it looks great) meanwhile the GTO addresses the handling issues the F-bird suffered from but it still looks like a 2-door lumina (another topic entirely).

Anyway LONG LIVE GM
