yeah you are right... equal length is difficult stuff though... and yep there isn't much space there for anything, motor just barely fits in there
update : Havnt done much as i just got a new daily driver and have to do a few things to it first . Another week or so and i should have time for the zed again . There is no way i will fit any kind of nice exhaust manifolds it will be very basic log manifolds for me I took the bellhousing to get machined thinking i would just have to get the 12 mm faced off , but after talking to the guy at the shop he wants to cnc it so it all fits in perfect but even that will only be around $200 so great value really .
another update its really getting along i did a bit more work on it last week and im really just waiting the the exhaust pipe to come in now and since im using the factory manifolds thats pretty straight forwards . i have to say the whole conversion is relatively straight forwards , at times there is a fair bit of thinking involved but there is always a easy solution . so , engine mounts done , clutch master done , electric power steer pump done intercooler mounted sump and pick up done things left : wiring exhaust intercooler pipes cooling system pipes modify bonnet ( i dont look forward to matching the 3 layer pearl with mottle the stoner painter did , i really should have painted the car my self ) It seems there is another 300zx in brisbane getting a turbo vh45 set up done at a work shop , is that anyone on here ?
its just a 450x300x100 mounted flat , the air out lets end up in a nice place but because of the turbo location one of the times has to go on a huge journey
manifold to turbo pipes done . full length 4 inch exhaust done and i actually fit it with out losing any ground clearance just too A LOT or work , ended up having to make a ovalised slip joint up the front just after the turbo which took a day , the the next section also took for ever but once under the floor it was easy . just have to do the wastegate set up now . Almost finished all the dirty laying under the car work which is great . just electrics , cooling and oil to go . Does any one have more details on the vh45 oil starving problem alot seem to have ? is it front braking and turning or just high rpm ?
pics!! The oil starvation is mostly present in the custom rear sumps, surges during braking and cornering. Just have the pickup sit really close to the bottom of the sump and make some baffles/trapdoors. If that still fails then follow what Chrispy did with the Accusump.
Seems to be a VH thing. Even the S13/14 guys spin big ends and mains and they use the standard front sumps normally. From everyone has been saying on Nico and V8Nissans is that the VH's are just built too tight and not designed for sustained high RPM, they need more clearance on the bearings. So with that and when people like us come along and make up rear sumps and chuck them in proper sports cars rather than luxury sedans it doesn't help at all. I wouldn't have a VH without at Accusump or a VERY flash trapdoored sump. And yes, more pics!!
my sump has alot of baffles but not alot of volume , im thinking of adding a acusump but would rather not as space is extremely limited . Maybe ill just wire oil pressure to the ecu so it cuts if theres a problem will this stop any damage ? or does it all happen to fast for that .
personally i would put an acusump in just for that built in safety factor. they can be hidden out the way to.
At 6000 RPM, engine is rotating 100 times per second. Depending on the extent of oil starvation, you can kill the engine and spin bearings in no time at all. How fast is your ECU gonna be?
the ecu will probably work at some where near the speed of light .Im not sure about the oil thing , i like the idea of those acusump but its more stuff in the engine bay and space is tight in there . i think ill just wait and see what happens . current update : I have removed the car cover so visitors to my shed can admire the unfinished project , im also unsure if my car is even currently registered . I might get back onto it soon.
well the oil has to drain out the bottom , but the drain hole will still be the lowest part so it should be fine . It will just be like a car going up a hill or accelerating hard .
Not quite, max inclination angle for almost all turbos is 15 degrees. You will have major oil control issues.
I can't see clearly, but do you only have one exhaust manifold gated? Even though it meets at the collector, I can sense some boost control issues there.
we will wait and see , i have a good feeling about it . the wastegate goes off both pipes . it goes to the middle of them with a divider going part of the way up the pipe . There are quite a few compromises doing this conversion turns out there isnt alot of space for a turbo and a big v8 in there .
