Hey,

got a highflow vl turb with t3 or t4 cartridge and some kind of modified rear housing.

i ran into dramas dummy fitting. ill let pictures explain.

as you can see straight up we have an issue with the dump pipe off on an angle due to the vl turbo mounted horizontal instead of vertical.

now im wondering without making a new dump or modifying the dump can i get it to fit properly.

as you can see if i hold it like so all the oil / water lines will line up, but if i modify the dump and bolt it straight up the oil return is horizontal not vertical.

any ideas... its asif i need to make some kind of t3-t3 90deg piece or if a rb30 turbo manifold would fit im not sure on stud pattern.

any suggestions would be kool, otherwise ill whack the stocker back on.

thanks,

dave

sorry i read it wrong...

have u tried rotating the exhaust housing?

No matter how u rotate the exhaust housing the dump will still stay on the same angle. might need to fabricate a new dump to suit mate.

for the oil feed it should be vertical so just rotate the 2 housings so that you get it in that position then get some braided oil and water lines, you then may have to rotate the turbine housing so you can get your pipe on your snail.

The most costly will be getting a dump pipe made to suit your turbo. probably around $400-$600 from your common exhaust shop.

im gona mod the dump myself. but ill try rotating it all. i knew you could rotate it but i was looking at the dump all the time going wtf !!!. but ill see how i go and then hopefully be able to mod the dump.

as i said this came off a R33 so i have no idea how the dump pipe worked out?

it would have had a custom manifold, possibly a high mount :) thats why the dumps like that

custom maybe, highmount no the dump would then be pointing at the bonnet. if a rb30 turbo manifold fits a rb25 thats what it would of been mounted on.

thanks for help, its on now, and im gona mod the dump on the weekend. factory lines fit, just needed the braided oil line. :down: the first time the rear housing didnt spin, but a whack with a rubber mallet fixed that. :)

if u put a peace inbetween the ex housing and the mani, the turbo would most likly hit the engine mounts when u put it in a car. Mod the dump, should b pritty easy, just cut the pipe off the flange, panel beat it to fit the right way and weld her up : D

if a rb30 turbo manifold fits a rb25 thats what it would of been mounted on.

nope. probs something like a hks cast low mount mani that has the flange facing down.

most important thing is to make sure the oil feed is at the top and drain is at the bottom, as close to vertical as possible

    • Have you not seen geospy.ai? It can now give GPS co ords to within a metre from a photo, even if it's a random photo you take inside. Supposedly at the moment only the government/law enforcement has access to that... Supposedly...
    • I've got the rear ones, they're certainly beefy. I need to take them to my driveshaft guru to check over, he's very fussy about the quality of components so I'll let you know if they are made of cheese by a blind man.   Are you in Australia? A mate just had a set of EN26 shafts made for his K20 Lotus by our fabricator which were quite cheap (compared to Driveshaft Shop) so if you can procure the CV's and draw what you need he'd make them for ~$800 for the pair.
    • Had I known the diff between R32 and R33 suspension I would have R33 suspension. That ship has sailed so I'm doing my best to replicate a drop spindle without spending $4k on a Billet one.
    • OEM suspension starts to bind as soon as the car gets away from stock height. I locked in the caster and camber before cutting off the kingpin. I then let the upright down in a natural (unbound) state before re-attaching it. Now it moves freely in bump and droop relative to the new ride height. My plan is to add GKTech arms before the car is finished so I can dial camber and caster further. It will be fine. This isn't rocket science. Caster looks good, camber is good, upper arm doesn't cause crazy gain and it is now closer to the stock angle and bump steer checks out. Send it.
    • Pay careful attention to the kinematics of that upper arm. The bloody things don't work properly even on a normal stock height R32. Nissan really screwed the pooch on that one. The fixes have included changing the hole locations on the bracket to change the angle of the inner pivot (which was fairly successful but usually makes it impossible to install or remove the arm without unbolting the bracket from the tower, which sucks) and various swivelling upper arm designs. ALL the swivelling upper arm designs that look like a capital I (with serifs) suck. All of them. Some of them are in fact terribly unsafe. Even the best one of them (the old UAS design) shat itself in short order on my car. The only upper arm that works as advertised and is pretty safe is the GKTech one. But it is high maintenance on a street car. I'm guessing that a 600HP car as (stupidly, IMO) low as you are going is not going to be a regular driver. So the maintenance issues on suspension parts are probably not going to be a problem. But you really must make sure that however your fairly drastically modded suspension ends up, that the upper arms swing through an arc that wants to keep the inner and outer bolts parallel. If the outer end travels through an arc that makes that end's bolt want to skew away from parallel with the inner bolt, you will build up enormous binding and compressing forces in the bushes, chew them out and hate life. The suspension compliance can actually be dominated by the bush binding, not the spring rate! It may be the case that even something like the GKTech arm won't work if your suspension kinematics become too weird, courtesy of all the cut and shut going on. Although you at least say there's no binding now, so maybe you're OK. Seeing as you're in the build phase, you could consider using R33/4 type upper arms (either that actual arm, OEM or aftermarket) or any similar wishbone designed to suit your available space, so alleviate the silliness of the R32 design. Then you can locate your inner pivots to provide the correct kinematics (camber gain on compression, etc).
