many RWKW's does that rag in the intake give you? All jokes aside nice lookin backyard set up. Did you make the manifolds yourself? and do both manifolds feed the turbo?

AVO has a twin turbo kit for the VT-VZ LS1 all up fitted and tuned they are about 15k, maybe a bit less, but still heaps of money.

I could have used this thread a month ago. Here's the VH that a mate and I are building with a single turbo VH45DE. Budget job so nothing flash in the turbo department. May be of interest to ISLEEP. Some original photos have not been recovered yet.

If you want to do it on the cheap, and install yourself. The best quality cheaper kit would probably be an ASE one. http://www.aseturbo.com/html/vt_vz_s...urbo_kits.html (http://www.aseturbo.com/html/vt_vz_single_turbo_kits.html) The singles are the cheapest. The twin mid mount is 3 K dearer. So $6500 doesn't include fuel system or tune. You will need injectors $600ish and a Walbro at minimum $150ish. A good 2 bar mafless will be anywhere up to $1000 bucks depending on time spent getting it right. Also factor in mating it up to your exhaust. another coupla hundred. You will need valve springs but @ around $400 del from the states. So realisticly your still not getting out for under 10K

good stuff....go the vh45. i take it its a late model vh45 due to the single runner setup. so i take it there is no space due to steering to run the exhausts ? i dont want to cut holes in the inner guards after i spent the past month of weekends working on them to get them 110% also is he just running log manifolds ? also i like the idea of the engine sitting so far back. im making so other custom parts to help push it right up against the firewall ps nice plenum, just needs injectors bungs and rails, good stuff

The engine is sitting forward quite a lot actually, we couldn't get it back any further due to the rack location. If you had lots of time to fiddle then you could get the engine back another 6 inches. Because the engine is so wide there is no room to route the exhaust out through the engine bay, even with the engine forward like it is. I am making some very simple manifolds for it, partly because it is a budget build and partly because there is no room for complexity as the rails are right where the ports exit. We are just making it up as we go really but it is working well apart from the rack/steering box. The plenum is something I made as a learning experience as I had never made anything that complex with alloy before. I am waiting on some injector mounts to finish it off. It is an early double port engine and I have used the original port flanges and welded the new runners to it. It is all very basic, no real money spent as I was just learning. No bell mouths or anything. Here's a link to the build so far. As I said, we are making it up as we go as I don't think anyone has done a VH45 to commodore before. http://www.performanceforums.com/for...php?t=67243620 (http://www.performanceforums.com/forums/showthread.php?t=67243620)
