Vg30 Turbo On Rb20?

[discopotato03]

Fair enough we we seemed to have learned that there is (was) a VG30DET that had a single ceramic BB turbo . Not being a big fan of Z31/Z32's I didn't know this engine option was available in other same (32) era Nissan luxo's . It does make sense that these OP6 VG30DET turbos were always a bit thin on the ground if these luxo's were more expensive lower volume cars rather than sporty R and Z series cars .

Anyway the thing is that the value in this turbocharger is the slightly larger turbine housing in a BB package with a slightly smaller compressor than RB25DET turbos have . AFAIK they should go straight onto an RB20DET with the correct sized water banjos/bolts and slight mods to the RB20s compressor outlet elbow - or possibly one off an RB25DET . From memory the VG30 part is a straight hose barb adapter where RB20/25 versions were a right angle bend . I think the 20s comp housing uses a slightly smaller PCD bolt circle and its adapter may have a slightly smaller ID .

RB25 elbow I think bolts on and may be the simplist way , cheers A .

^^dont mean to constantly contradict you but the vg30dets and vq30dets are common in japan and are available from importers as these motors were in production from (at least) 1987 Y31 thru to 2004 Y34 therefore a plentiful source of engines/turbos /halfcuts etc

All I can say is that for a time the OP6 type turbine housings were not super easy to find compared to the RB20 and 25 sized ones . Not impossible but took some searching .

Well....no. VG30DET turbos have been readily available since forever. Used to be a very common swap onto R32s in the early 2000s.

Yes they were....but try to find one for sale now, I dare you

Want to buy one? I may have one here :-P I don't rate them on RB20s, or in general - now you can get TD05s from Kinugawa in T3 flange you can get comparable spool and way better power brand new for a reasonable price

dare accepted. . vg30det fs on boostclassifieds

$500 (engine including turbo) :-p

[niZmO_Man]

NEO6 turbos go for $350-400 lol

I wouldn't need too many excuses to get rid of that ceramic turbine because they are firstly fragile and secondly a bit small .

Anyhow it's the OPs call , his car his money .
