Here is my graph on a 6262 by with .84 TS setup and 93 octane gas 611 at 19 psi 550 at 15 psi I think if I had 9:1 Cr pistons my torque would've been a lot higher I'm using JE 8:3:1 CR pistons and Tomei 264 cams.

It's been a long time but here are the end results of the build https://m.facebook.com/story.php?story_fbid=773329676088103&id=142284982525912&_rdr

Thanks for the quick reply guys. Haven't removed the factory restrictor. I'm running a -4an feed line and a -10 am drain line. Drain line is pretty straight down with now kinks. I also did a leak down test and compression test on the engine. Got 128 psi on all 6 cyl.(running 8:3:1 CR) and dry leak down test was 10% on al 6 but #1 13%. Not sure what other options I have I'm getting 45psi. Pressure at 2.5-3krpms and over 60 psi from 4k up

Made 611hp/449 at 19 psi, 93 octane Hitting full boost around 4.3k rpms

It's been a while but here is my Dyno sheet from build Rb26 precision 6262 at 19 psi. Car is running good other than its smoking from turbo. Anybody here using restrictors? I just put a .030 restrictor and stopped smoking but not sure if I should drive it.(n1 pump)

Finally got my car tuned.@19 psi, 93 octane 611/449 tq on precision 6262. Lmk what u guys think

When i bought the swap already had pistons and rods so decided to give it a shot instead of spending $1k on pistons. They were brand new 0 miles. Dont think will affect a lot on the setup

600 hp at the wheel. Using methanol injection. I dont have access to e85 in my area. Was thinking to add a inline pump

Alrite guys, Kinda new to the forum. Im located in the US and currently close to finish my rb26 build on my 240sx. want to see what u guys think and what i might be missing.

Haltech plug in tomei 1.5mm oil restrictor goal 600hp What fuel pump you guys recommend? Max rpm rexommended for this setup? Also have ross tuff metal jacket damper

thanks for the advise guys,after looking at SimonR32 chart im sure ill be reall happy with it. Ordered the precision 6262 ball bearing T4 .84 divided housing. do you guys use a restrictor for the oil feed? I will update after tune. I'm not sure if I had a bad combination on the sr but I just got frustrated with it and that's why im going RB26 this time.

I'm just blind estimating. I come from a sr20det swap with a gtx3071 and I didn't see 15 psi till past 5.5k rpms. If SimonR32 can show some proof of the spooling I'd be happy with the 6262. Now if the 6266 is behind just a few hundred rpms i will consider it as well.What rear housing? Would like to see the difference of 15 psi vs rpms between the 6262, 6266 on a 2.6 with similar cams. Thanks for the help guys. There is not many people with rb26 in my area so ita hard to get advise

hello guys, now to the forum and excited to be almost done with my rb26 build going into a s14 240sx. like most of you guys still debating between precision DBB 6262, 6266(only two option im looking for, nothing else) for my twin scroll setup. im aiming 550-600 whp on 93 octane and water meth kit. here in the states is kinda hard to find e85 in the country wich forced me to choose methanol injection or just pure 93 octane. looking for a decent response no more lag than 15-20 psi @4k. psi goal is around 25-28 with metanol inj? .chime in guys and tell me what you think. note: decided to post my setup after reading 106 pages of information, kinda overwelmed with all the information and my head is just spinning around lol. thanks for the help JE 8:3:1 eagle rods ARP main studs crank polished, collared, N1 pump, 9.8 qt oil sump, acl bearings greddy 1.2mm HG Arp head studs supertech bronze valve guides, springs and retainers. 3 angle valve job Tomei type B poncams stock IM, ID 1000's using haltech plug in, 3.5 bar rmap raw brokerage twin scroll manifold with twin 38mm tial mv-s, 3" downpipe(made for 6262,6266) need advise on fuel setup, have a twin entry fuel rail and currently a single walbro 255 in tank that was using on my sr20det swap.
