Help me find a Grand National Turbo!
 
I am looking for a 'built to spec' turbo, to match against the turbos used in the 84 Buick Grand National.

Though I havne't drove the car in a while, I am pretty sure the turbo is shot.

Anyways, I have tried contacting dealerships for this turbo but appearantly 2 years ago they stopped marketing the turbos themselves. So I am hoping someone here might know where to locate one or at least a turbo that is equivalent and works with the factory bolt pattern for the headers.

On a relative note, I am also looking for the intercooler setup that was featured in the later model GNs. I have had no luck finding any sort of a 'conversion' kit, and I'd like to keep the car as factory as possible for value.

Thanks!

The GN is the reason the technology for modern turbo cars exsist. GM didn't want people to know it, but the GN in bone stock form with ONLY drag radicals could stomp the piss outta a brand new C5..

My friends GN is 800HP...

The compressor surge comment was b/c they don't have a BOV ?... leave the line with 17psi on a 3.8L V6 on slicks, then you'll say....."buick"?? "WTF" !!

I wish they didn't look like 87' buick regals... Ever heard of a BU-Stang ?? hehe, got my GN parts in my garage waitng !!

Type R's are slow only low 15 second 1/4.... so anything can basicaly stomp a C5.

I love GN's i just hate the compressor surge...

my friends has 32K orig. miles, and he flips his wig if you shut the door using those leather straps on the inside of the door... We were going to put his car is storage for a week to swap his dad's motor, and he refused to let my 2 year old daughter ride in it, so we had to wait at his house, he is CRAZY ---- !!! No less the paint on his GN looks 100xs better then my 01' focus...

I think he ment c5 as in a C5 corvette, not a b18c5

Yeah, this GN was my grandmothers car. Its sitting in the shed behind my house right now, with around 22,000 miles on it. I think we last were offered $29,000 for it as is.

I am pretty sure that the exhaust is cracked, and that the turbo is warped. As far as I know, yes this car did not have a blow off, but it also has a different intake stream then any other 'modern' turbo vehicle. I'll have to take pics when its cool enough to take it out.

Re:Help me find a Grand National Turbo!
 
My friends car was bought with 27K miles and the orignal tires and air filter were still on it.

He paid $12K for it, but he said I was really worth about $18-19K, but close to $30K sounds like what a GNX might go for ( BTW the GNX was the fastest prodution car in 1987 and that includes ALL ferris and porches ).

GM also built the fastest prodution truck ever built too ( including the lightning ). The 92' GMC Syclone S-10. It ran "13.00" from the factory and waxed the piss outta the vette back then and tuned it could wax a ZR-1, which was $60K vs $27K syclone.

Both cars were killed b/c they were effecting vette sales ( unlike the newer F-bodies which weren't selling to well ).

Score = vette 2, turbo V6's 0.. That's why I hate vettes, rich wennier cars, are the reason that GM is getting its ass stomped by 4 bangers now..

The lightning and typhoon(i know they don't make them anymore) are in for a suprise this year when dodge brings the Ram SRT-10 to the dealership. they expect 12.50 quarter and it is not even supercharged!

Re:Help me find a Grand National Turbo!
 
Keep in mind the older vipers only ran 12.80... A truck with no rear-end weight is going to be VERY hard to hook-up.

slicks will make it a different story.

BTW, how much is this V-10 beast going to cost ? $45K ??

a syclone with VERY light mods could run low 12's, high 11's, but the RAm V-10 could also handle a 200shot, so...

Time claims are gay... Check out the times that street bike magizines publish.. all the 600's are supposed to run 10.8-10.9 and the bigger ones are in the high 9's, but 99/100 people can only get them to run mid-high 11's for the 600's, and mid-high 10's for the 1000s.. The same goes for SRT neons, viper, Z06, cobra S/C mustang, and a lot of other cars that claim very low times.

Motor trend says the neon runs 13.9, but I've seen 3 different ones run and the fastest was a 14.3, and the other were HIGH HIGH 14's..

When i see a SRT ram run 12.50 at the track in stock form, thats when I give props.

Still dodge has grown some big balls, they should knock GMs lazy ass's out... GM used to be good, but now, all they wanna do is S/C saturns and cavilers ( no offence meant ). Where's the Turbo camaro ??? heh, right, we get a bitch ass GTO.

The caviler in Aust. is a 6-speed, 240whp, turbo, awd !!!

i don't think you will ever see a FI camaro.

supercharged if anything and that would be a longshot

Re:Help me find a Grand National Turbo!
 
I know, just saying... the STi and the EVO8 and the SRT neon ( with slicks ) could all stomp a mud hole in the vettes ass, and GM is just bending over and taking it.
An all alum. 427 sounds good, but so does a BJ from Pamila Anderson.... Both will never happen.

Dodges original claims for the SRT-4 were around 14.50 - motor trend and the others use a roling start on their tests which takes like .2 - .3 off the quarter mile times.

I happen to have a turbo neon rt that runs faster than 14.50 with no intercooler and 6psi.
I was just sayin' the SRT-10 was cool as well as the bike that dodge put a Viper Motor on. YEAH! i am gonna get on that :o.

anyway while we are on the subject - a custom fabricator in the neon community has already replaced the tiny little turbo on the SRT-4 with a T3/T4 and put nitrous on it too! Dyno results to follow. they expect 11's without the nitrous and it still costs less than an evo 8 or a wrx sti.

well, this is HMT

I don't have a problem with neons, but I seriously don't show them any respect. I mean honda could have built the s2000 with a turbo.. or if they were crazy, they could have built a crx with h22 turbo and call it a 12.00 sec car from the factory.
