What do u guys think about this...

[1 Bad Burb]

well, been thinkin, maybe after i finish the burban's s/c problems, i may decide to buy a lt-1 motor, built it up and swap it in to the burban. i mean, fully built bottom end, blower cam, forged internals, the full works... prolly about a max of 4g's into the swap. ontop of that, put the ati blower on it...

 

OR...

 

buy a 86' Buick Regal T-type, has a few mods on it, new chips, thats all i know for now. guy wants 5g's for it. it dynoed @ 280 rwhp & 400 rwtq. i think my buddy said that, that car does 12's in the 1/4 mi.

 

so what do u guys think? i'll gte more info on the car. the LT-1 i can get alone just for 1 g.

I like the LT1 idea.. but what about a ls1.. a 5.3 would be a beast in that thing...

[black&grayHD]

I'd pick the T-Type

[OUMike]

280 rwhp doesn't equate to 12s. More like low-mid 14s. Quarter-mile has much to do with hp.

 

I'd definatly go crate LT1/LS1. How about something different like LT4?

[Tucson_02Silverado]

The 3.8 just can't give you the torque you need.

 

The LT1/4 is the better choice

 

But like was mentioned what about an LS1

or even a 5.3 or 6.0. Seems to be a few 5.3 on ebay for less than $2K

Um, not true. Its not how much horsepower you have, but how you use it. A close friend of mine ran 11.0's with only 338 rwhp. But he has tons of suspension work done to the car to make it run like crazy.

I'd go with the 3.8. You can very easily make them have 600 hp and they get extremely good gas mileage. Not too many people will like the v6 idea, however. I do not believe anybody that actually owned a grand national would doubt the engine in a surburban. My grand prix gtp made 242 fwhp and ran 13.7 in the 1/4.

[GlennRMK]

I'd go LT1/4 or LS1.

 

Either one is good.

[1 Bad Burb]

just to clarify, im not takin the 3.8 motor from the GN T-type, im buying the whole car!!!...LOL that or i might buy the Lt-1 since my buddy is sellin it for $1000.

 

i may just not buy anything, save up all my cash and build the sh!t outta the burban... new tranny, new rear diff...

 

this is just a thought, i may or may not do this, but i hear that the Regals are badass..and rare!

The GN/GNX's are quite capable of 12 second 1/4's with a few bolt ons without nitrous. I had an 87 GN with a ATI Pit Bull chip (22 lbs boost!) bigger injectors, ram air/K&N and a larger intercooler. It would run 12.8/12.9's all day long. Very fun car! I'd go for it!

Depending on driveline..338 hp is close to 400 clutch hp. That is WAY more than the power described in the car he was talking about. Suspension does have plenty to do with quarter mile time, but without power it doesn't matter. Lets use Corvette ZR-1 for example.

 

ZR-1s produce roughly 332 RWHP. A 1990 model is the quickest year for these cars due to lighter weight. These cars run 12.3 or so from the factory. With this info it seems highly unlikely that a like a GNX that has an infereior drivetrain and suspension (even with a few mods possibly) to the ZR-1, and producing 50 or so LESS ponies would run a similar ET.

 

I did a little research on the GNX. I checked various websites that clamied this:

0-60: 4.7 sec

1/4 mile: 13.4 @ 103.4 MPH

These times are definatly beliveable due to turbocharging.

 

The GN/GNX's are quite capable of 12 second 1/4's with a few bolt ons without nitrous. I had an 87 GN with a ATI Pit Bull chip (22 lbs boost!) bigger injectors, ram air/K&N and a larger intercooler. It would run 12.8/12.9's all day long. Very fun car! I'd go for it!

 

The mods talked about in this post are major jobs. They would result in more than 280 RWHP. Not to mention more boost (22 up from 18).

 

If someone can explain how this particular car would ZR-1 times with less power, I'd definatly be interested.

 

Sorry for the ZR-1 examples, just happens to be a car I'm very familiar with.

If you decide to run an LT1, you'll need the LT1 corvette accessories brackets and corvette accessories (A/C, P/S, alternator, etc..). You'll still have to notch the frame rail to get everything to fit, but it will work. Street & Performance has more info on that if your interested. I researched doing that to my Tahoe a few years back, but just decided to leave my lower end stock and throw on heads and a lumpier cam.

OUMike, great summary!

 

American Muscle man, i know, theres a lot of work into it, i could even get a newer motor like others have suggested... more potential in a "newer engine" than an ol' LT-1.... either way, the T-Type is tempting me, but i don't have the time for it...too many d**n problems on the burban, s/c tuning, leaks, etc...

 

but, i'll keep my options open!

OUMike, You do have to remember that the GN/GNX/T-type is alot heavier than the Vette. Weight also takes into effect. So you could have a 600 RWHP car that weighs 3700 lbs, and it could only run low 11's not having the proper suspension setup.

 

But you can take the same car, install the correct suspension setup and the car will run 9's (with a good driver)

 

BUt I do see your point.

[OUMike]

Wouldn't it have to be lighter??

According to a few sources...

1987 GNX - 3545 lbs

1990 ZR-1 - 3505 lbs

 

Is this enough to make a difference?
