Outer Limits 4x4 Board

Have you guys even read the thread? It is not compound turbo, high flowed ct26

This thread is very old. It is only still going because the odd question pops up and I am happy to answer them.

The engine was sold and the guy who bought it didnt have the funds to set up a compound turbo at least for now, so I made a high flow CT26 (not over top, just std CT26 with 1HDFTE 46/65mm comp wheel). He has fitted an intercooler and 3" exhaust. After a tune up the results will be posted.

Some of you guys who ask all these questions - I wonder if you actually read the posts first or have any idea how long it takes to do some of these projects while having a life......

I love doing the theory and happy to share it, but the theory/engineering needs to happen before a build. The potential combinations are so varied that you would stand a better chance of winning lotto than going and getting two off the shelf turbos that your mates mate thinks look big enough and bolt them up with a 6" exhaust and achieve amazing results!

Getting it into practice takes time and sometimes doesnt happen for a myriad of reasons. My ideas to reality ratio probably exceeds 10^10:1......

I realise that I'll have to buy new valves and seats, but which ones, and how big can you go? I'm looking at a 2H also, rather than the 12H-T, if I could get a 12H-T for a more realistic price I'd go that way but I've already got the 2H.

i just turboed a 2h and it is sweet, got a manifold from ROTAMASTER in melbourne, used a t60 turbo rated at 550hp, put the snorkle on the left hand side, ran a oil feed from the block and an oil return straight down to the sump. the only tricky bit was the dump pipe, i used one of a rb30 turbo that was in a patrol. but that is pretty much it. no blow off valve, intercooler or oil cooler. Just a turbo timer, boost guage and a pyro guage.

A couple of problems there. A t60 is completely the wrong turbo for a 2H, the 2H isn't strong as the 12HT and the turbo timer isn't needed.

sure was the wrong turbo, was'nt enough exhaust gas to spool it properly. got a t04E on it now and it is still a tad big but spools up heaps better

Still way too big unless you are using a modified fuel pump, an intercooler and looking to over 200rwkw
