DR 32R

Great combination of sleeper grandpa, and grunt. Like it.

Consider going the other way more stroke, rb26 crank or after market stroker crank. Potential earlier spool (less lag), more power with less boost. I think Upper Rev range in the RB 25 is improved more by quality springs retainers and head work than bore stroke ratio.

It was a "cheap GTR" and he's building it. I think the buy was OK. Nice effort on this build too.

http://www.skylinesa...-drag-or-drift/ This is Sydneykids take on oil control. it seems most RB devotees support oil restriction in a rebuild.He advocates blocking an oil feed in the RB25. Mine and the Mafia is restricting the 2 block feeds.

You seem obviously in pursuit of the ultimate "response" combo. Is such early and I assume non progressive "response" really be that great to drive in 2 wheel drive? Aren't you just getting early "tail out" via traction loss. A common condition for me in my "responsive" via 4L F6 Ford. On topic I'm trying twin scroll, split manifold, twin gates, with VVT with stall converter to deal with lag in my gt35 based set up ATESSA in my gts4.

Sounds like the best approach of all.

Three head oil feeds on an RB25, two block feeds to head, one for VVT. If you restrict two block feeds, you still have three feeds to a hydraulic head. People have adequate cylinder head oil with the VVT feed, one blocked, one restricted.

And when a rebuild gos right, there is a special satisfaction.Oil control mods are a reliability mod, needed just as much as forged parts.

It seems even with a standard oil pump,oil restrictors are advised, 20 bucks a restrictor, there are a couple of billet gear pumps in the parts for sale section. Price of these items will be small fraction at end of build.For your goals, quitting while ahead and buying a used RB25det for $1400 looks good. (price of retail after market oil pump).

The translation from the thumbnail only says "Ultrahigh performance and extravagance" and where to purchase it from. The phrase makes me think of your car.

Enjoyed both articles. Thanks for posting. The r32 GTR remains amazing value.

No restrictor in the rb25det packet for me. Is it only with the rb26?

I guess I wanted one, they look bespoke. They are individual order for rb25det over rb26. I copped a serve from the manifold guy that it will spool later than a Plazmaman plenum. I haven't seen a comparo, There's a thread on Greddy vs Plasmaman. I just wanted one but the other factor was getting the throttle body, and fuel rail as one package. However it's coming off for adjustments so the VVT will work, something that concretely affects spool. The HKS Step 1 cams were chosen to retain VVT.

At the moment weekender. The build has taken long enough to forget why. I have a Magna and an Audi for daily duties. I had wanted to drag it, but feel less inclined.

Interested in reo.

What it's going into.

The Performance Metalcraft sump is also pretty nice. I hope it will help keep this engine alive.

The engine assembly continues. Hypertune plenum and 6 Boost manifold are pleasing products to look at. Hypertune plenum needs fettling for VVT.Got some compliments on the 6 boost twin scroll manifold, with twin scroll turbo combo.

1) Don't know. 2) is fine 3) 1.5mm restrictor

So how do the AWD block RB25s neo and non neo differ from the RB26? Many of the Stagea blocks I've seen have interchangeable sump and sump parts with the Rb26.

Pity no C4 for all wheel drive yet.

Nice result, which fuel?
