wat do i need to convert an 85 gn to intercooled or dose someone make a kit???

[moenning1]

Or could i use a 86 87 set up??

I know there are a bunch of threads on this already, and it can be done to use the 86/7 setup but you basically need an 86/7 parts car from what i'm seeing and it is very pricy.I think there is a company that makes an intercooler setup for these cars but I cant think of who it is off the top of my head. I have been wondering myself if it would be feasible to make your own up and downpipe and move the charger a little, and somehow change the piping so you can have the throttle body on the compressed side of the charger. It may help with the lag i'm hearing about on these cars when you add an IC, but i'm not sure. I have very limited knowledge when it comes to turbo gas engines as all my knowledge comes from the diesel world where everything seems so much simpler, and my GN isn't even running yet

I know someone has to make a conversion kit for sure i dont like the fact that my gn dosent have an ic and i know it will run cooler and give me more hp

 

[SloGN]

just add alky injection and it will more than help unless your looking for 450+ hp... the installation is way easier..........

 

[moenning1]

Yea true thanks

 

[Rafs-T-Type]

I agree with slowGN, but I think spearco makes one.

I guy around the Bowling Green Ky area has been running a 85 hot air in the high 11's for years now. He just added alky injection.

All but the long block basically, but you still have to tap the block for the turbo oil return...

 

[SloGN]

It's really not work the effort unless you are tring to go all out. It just depends on how much power your tring to make.

 

[crashedout1]

You can make your own if you can rotate the turbo

 

[Boostnitup]

I purchased a replacement motor ('87 T) and figured it was easy to convert my '84 GN at that point.

Jack Cotton set up a Front Mount Intercooler set up for me.

I had a Spearco at one point in time. (and another high end custom system... I actually got mine... then sold it .

 

[we4Mateo]

I think if I ever did a hotair, I'd just do 80's with E85 setup.

 

[Anarchy]

wen you convert can u use the same heads? im doing mine as we speak

 

[Squid4life]

Yes, can use the orig heads. Most likely they are all 8445s.

 

[Anarchy]
