I built a temporary up-pipe and did a couple pulls with no hood. Very leggy down low but pulls just as hard or harder actually at 9psi as the old turbo at 12-14. I need to start fabbing the downpipe so I can run my wideband. It will need some tuning down low to reduce the lag and achieve safe afr's with higher boost. Planning to run about 16psi and looking for a target of 300-320hp later on on stock internals.

Built the 4" to 3" cone and downpipe, tig welded and on our way.
Builds boost a noticably bit quicker with exhaust hooked up. Full boost around 4500. running 9psi. AFRS are near perfect on stock ecu suprisingly. Runs rich on factory set-up.
SCREAMS! sounds insane, like really good. Can't beat that externally gated I6 sound.

Ran the car on street tires over the weekend, best pass on 16psi was a 12.699 @ 109MPH. 1.977 - 60 foot.
Time to find some slicks if the wallet permits. Easily a low 12 sec car if I can find the 60 foot times.

Interesting build! I love RB's and love seeing swaps people don't regularly do
Ive had an rb25 in one of my older Nissans for almost 7 years now and its been a wild and crazy build
Good to see you throw down a 12 second pass in it!!

Here's an update since last year.
Re-doing the custom front coilovers we did a few years back with some BMW CX Racing fully adjustable coilovers. The fronts for now and will get to full coilover in the rear at some point.
Let me know if anyone is looking for Koni Red inserts or Tokico Illumina rears.
Old coilovers 175-350 lb springs / koni Red & Ebay camber plates:
New CX racing 32 point dampening adjustment, 447lb linear springs, + camber plates I built on the Mill.
To do list is getting long, Roll cage, seats, rear coilovers, RB25, RB25 transmission... list goes on.
