Very nice! I noticed the injectors are a little small for the turbo. Are you using a lot of meth? What's your injector duty cycle and meth nozzle size? Just curious. You are pretty lucky to work where you work and have the hobby you have (or maybe you have the hobby because of your job?) :-) Anyways, really nice.

Nice setups guys!I sold off my RB20 but I'm planning on doing a RB26/30 eventually for a S30 chassis. Hopefully pretty soon. I have a couple of goals to hit with my Z31 then it'll be sold off to fund that. I love nissan 3L's! VG30 VQ30 RB30 oh my!

Still needs:New paint, CF hood, mild cams, dual bosch 044s, reworked fuel lines, larger injectors, better IAT sensor, custom knock sensor adapter/digital filter for EMS, nicer brakes, roll cage, drive shaft loop, scatter shield.

My buddy owns this car now, was featured in Import Tuner mag think April or May '11 edition. It insane super quick :ohno: . He had a S14 with Sr20det was going to do a Rb25 swap. But his S14 got rear ended at 80mph on freeway, he lost control and hit the wall divider at around ~80mph , then got hid on the side again. Car was a wreck, he lost conciseness, and was air lifted to ER. Anyway insurance totaled it, he bought it back, sold all parts from it, and scraped the chassis, and then sold the RB25 ;-( . He said he was done with tuning, but I knew he wanted an RB, he drove my Rb20 S13 when he still had his S14 Sr20. Well what do you know, one night I was at his house drinking with buddies. His like hey I want to show you something, we went to garage, and I seen this S14(above), but I knew I seen it somewhere else and there was something special about it. I had to plea and beg him to start it as he didnt want to pop hood, the second it fired up, I was like :bowrofl: , Rfu(k!ngB lol. Thought I share this with you guys, and whereabouts of the car. His not a member on Nico think his on Zilvia tho.

Looks real good. Nice and clean. BTW: what size hoses are you running to the valve cover breather nipples?
Is that -8(1/2") or -10(5/8")?

Its kinda dispointing when people drop 10k just into the engine to make this rediculous over powered slow spooling street car. I went for simple, fast and clean.

Car is a 1991 Nissan 240sx

Engine is Rb26dett

Wiseco pistons .020 over
Stock rods
ACL Race main bearings STD
ACL Race Rod Bearings STD
Greddy Metal headgasket
ARP Head studs
New valve seals
Stock valve train
N1 Water pump
Stock R33 oil pump
HKS GT-SS turbos
Stock injectors
Nismo FPR
Vi-Pec ECU
Custom intakes with K&N Air filters

440whp with turbos that spool as fast as stock.
All I'll ever need.
For 1/4 of the price then what I'm seeing posted here.
You only need to address certain key points to make it fast.
Theres fast and theres pointless/overkill.
Cleaner then yours.

Outside of car is currently in the middle of block sanding the primer. Will be painted same color as engine bay soon with a stock like two tone.

Pic of car off to tune. Thats the stock color but like I said all the body work is done and its been primed and 80% block sanded. Gonna reprime, block sand again, then paint.

I love what you've done with yours and I would be proud to have built/drive something that clean. It's super clean, tastefull, and I'm sure it's a blast to drive both down the twisty's as well as at the 1/4 but..............

Newtype, your comments are cocky for somebody who obviously doesn't know what fast it. You car looks "quick" sure. So was mine. If you say it's not fast enough, you either have never been in an actually "fast" car, or you need to dig the sand out of your vajay-jay.
