I am currently building a 5.3 with two 66 mm turbos that I had laying in my shop. It's going in a 1965 c20 flatbed and I can not for the life of me find much info on this. I have a slight understanding of what needs to be done and a lot of post on here have been helpful but I have been looking for some pictures of tt's in an engine bay with lots of room

Well pics of twins in a f-body based forum with lots of room are not going to be plentiful. I can think of atleast 5 people with TT setups though. Lastls1, mrstepheneades, transam96230(?), theres a old nova or chevelle with some, blackws666 i think went TT

Single turbos are usually more cost effective, take us less space, and are less complicated.

If you're looking for pictures of twins, look here:

I wouldn't call it an F-body forum....

You should look here, this is my favorite section of LS1tech

Twins stuff just usually cost a little more and like has been said there isn't much room unless your a racecar lol.

Was this.......


And now im going this route......

More people can afford fbody is why there are lots more of them than other cars on here.

The majority of cars on here are f-bodies. Not saying there isn't others but as you scroll thru the FI section 4 out of 5 new builds are usually f-bodies.

Still lots of good info just may not get many pics of a swap vehicle like that one. The Performancetrucks at the top of the site would net some good info aswell.

Love how your setup is pretty unique

Twin 66s on a 5.3 would seem to have a lot lag on the street. A 6.0L would be a better option if you already have the turbos. What a/r housings are on them ? My current 6.0L has twin 6165s in a 69 chevelle and its getting crowded under the hood.

1.00ar 73mm turbine divided t4 on the 66s. Don't really care about instant boost on the street. Its going to be a cruise around weekend car with 8 sec track potential lol. And ill not be visiting the track that often. Jose told me that these would do well on a 5.3 platform with the right cam and converter. 6.0 would be better but a 5.3 has a thicker block I believe and 30psi is gonna push the stock gm blocks no matter which one I choose.

Seems like it would be hard to get the sizing right on the first try. I plan on starting small and working up as/if needed.

I even thought I had a lot of room until I tried fitting two of everything in the engine bay. Twin turbo setups do get crowded, are twice as expensive and twice as complicated

I'm running out of room real quick on mine, and lots more crap to find a place for still!

I envy your hood clearance. I'd like to use one of those intakes, but I'm not sure I could see over it.

4" glasstek cowl. It's not bad at all from the driver's seat

Twins are a pain. Plus the limited space factor..... I am going big single next time around.

I had to cut a little of my ws6 hood away for the tb area of the proflow.

This 2" just did clear the MP112. I think another 4" might require mirrors to see around.
