does anybody know where I can get some good turbos off of a GN or regal. And maybe an intercooler. I will build all the tubing and such, but I cant find any good turbos I can use. I plan to add twin turbos to my 383 in my Malibu
ryanwitski said:I'm not an expert but i belive the GN turbo will be a little small. Most F body guys running 350-383ci use garrett T3 turbos. You could get them from ebay but with a turbo in my opinion eithier from a shop or good source. Most ebay or auction turbos look good but if you can not touch them and feel how wuch slack or play there is you don't know whatyou are getting. Then again you could getsome cheap and get then rebuilt (don't know how much that costs).
Cutlassjim said:Stock GN turbo's are t3's. All that the t3 denotes is the exhaust housing style. A t4/t3 hybrid like all the Honda guys yap about is just a t4 exhaust housing with a t3 center section and compressor housing. The newest rave from Garrett now is their GTxx line ranging from I think 12 to 45? with an R at the end meaning dual ball bearing center section.
And airflow wise two stock GN turbo's would be good for around 700-800 horse so their not too "small" persay. When most people say small they are talking about the A/R ratio or size of the exhaust housing being too small. But if a 3.8 can breath alright out of one then a 383 (5.9 liters?) should be able to breath fine out of two.

Turbos like higher rpm engines and usually kick in the boost at higher rpm's
I am going to use two turbos off of a 2.2l engine. this will give me the boost of about a 4.4l engine.
