Turbos? So I put a pair of t70's on my stock 4.8l and they seem to be too big. They start to spool around 3000rpm. I am just wondering what size turbos I should go with to get 600RWH with my stock engine and get them too spool earlier? I bought these before I was on this forum and didn't really know what I was buying. Any advice would be appreciated.

I don't remember all the specs, but yes they are the ebay t70s and it says on the houseing a/r70. It was street tuned and they come on very hard at 3000 rpm. I'm using 80# injectors and a1000 fuel system. I zero running problems, I just think performance would be better with smaller/faster spooling turbos. When the car is at idle the turbos even stop turning, thats why I think the stock engine is too small for the turbos.

Unfortunately I bought the HPT basic and it doesn't log. I had the car tuned by someone on the site and it does run great once the turbos start to spool. The wide band stays around 11.5:1 and the tiiming is around 17*.I was told when I first joined and started my build thread the turbos were probably too big. They work they just don't come on till about 3000 rpm. I'll attach a copy of my tune.

You want a pair of T3 turbos, with nothing bigger than 60mm compressor inducers. Even smaller would be slightly better. Like a pair of GT30s. T3 .82 would work well, and so would .63 if you are more concerned with spool( probably about 300 rpms difference).

Old school To4E 57 trim would work too
