    E.o.i- Vh45 With Z32 Loom. 5 Speed Gearbox And Twin Plate Os Clutch

    in For Sale (Private Car Parts and Accessories)

    Posted

    I'm considering going a different direction with my engine conversion, details are as follows

    -VH45DE pulled from a Q45 halfcut myself

    -timing chain guides replaced with metal backed ones

    -all accessories were tested and working (except the air con which couldn't be tested but didn't make any bearing noise)

    -comes with a complete Engine loom that has been spliced into a Z32 loom to plug into the Z32 body, easy to change for a skyline body loom and i have all the pinouts and diagrams

    -Adaptor plate to suit the VG30DETT gearbox

    -VG30DETT gearbox included with a machined bellhousing so the flywheel doesn't need to be spaced

    Can throw in extra's like

    -Twin plate OS Giken clutch

    -davies craig electric water pump

    -rear pickup sump

    -Garrett GCG T76 turbo

    -Tial 46mm wastegate

    -turbosmart megasonic BOV

    -GTR cooler

    and a few other bit's and peices

    PM me if interested. I'm looking for interest around the $3.5k-$4.5k depending on whats included. I can pack it onto a crate to send interstate but it will be around $400-$600 i'd say

    Holset Turbo's

    in Forced Induction Performance

    Posted

    Falc, I had a look at the compressor maps when i was choosing a turbo for mine and had difficulty getting the correct compressor map for the turbo I was looking at so in the end i just looked at the power it was making at what boost on as many cars as possible.

    I came across the map that is for my compressor after I pulled the turbo apart and infact the compressor is rated to flow an incredible amount. on my setup at 20psi it will flow just a shade under 47lb/min at full noise. at 3500 rpm it will flow 22lb/min. and that's only 220odd hp.

    I might have got my volumetric efficiency wrong and therefore my calc's could be wrong. any once you put the compressor in a cover and bolt a turbine in a restrictive side all the maths go out the window. I am guessing that the 12cm^ or even the 10cm^ @20 psi with these turbines will still flow enough for 350rwkw. I am basing this on the fact that a .63 rear can flow 300rwkw and the 10 and 12cm considerably bigger.

    so the HX35 looks like it will flow 47lb/min. @20psi. that's 350kw. the 10cm^ housing looks like it will also cope with this power level and the standard RB manifold will start to choke at 300rwkw and that would be approx 330 to 340 flywheel kw?

    so in theory the HX35 looks to be the perfect turbo for us.

    I have included the map for mine with a line at approx 20psi.

    doesn't really help me though because high airflow at high boost doesn't suit my engine. Everyone seems to be putting these on smaller engines and making a lot of power at a lot of boost, most of the holsets will choke on my engine before making the same power. I need around 10psi at the manifold to make 600hp. I don't want more power because I'm running an OS giken twin plate through a Z32 trans and R200 rear end, really not a fan of blowing drivelines

    Whats the biggest petrol engines you guys have seen single holsets put onto? any 1UZ's? what were the results?

    Holset Turbo's

    in Forced Induction Performance

    I've been studying these Holset turbo's for countless hours, finding compressor maps on these is so damn hard.

    The problem I'm having is that the engine I want a 600-700HP turbo for is my VH45, looking at many of the holset compressor maps they don't have the width at the bottom of the map to do what I want, but look to be awesome for high boost. I need 60lb/min @ a pressure ratio of around 1.7 the turbo's that seem to fit are

    HX40 B8574M just on the 60%@60lb choke line @PR of 1.7

    HX40 B8584M inside 65%@60lb/min @PR of 1.7

    H1E 8284AD inside 65%@60lb/[email protected]

    H2C 8625N almost 70%@60lb/[email protected]

    H2E 9551BA inside 70%@60lb/[email protected] but it comes on at 35lb/min which seems very late, I've calculated around 18lb/min @3500rpm

    I've posted the above for reference if anyone is searching as there really isn't that much info for holsets on larger petrol engines.

    Does anyone know any more info about the turbo's I have posted, particularly how many blades they have on the compressor. There are so many 8 blade holsets around but no 8 blade holset I have found will flow the number I need at low boost.

    possibly, but they aren't comparing the two, if holden released a 1600kg retro torana with the 6L V8 for $45k it might get good reviews as a package because of the performance etc for it's class, if at the same time BMW released an M4 with more power than the torana and the same weight but a $70k price tag t might get the thumbs down simply because it doesn't deliver on expectation of the brand and pricetag. This doesn't mean the people giving the review are bias towards holden, it's simply that they are taking the car on it's merits
