ZT-R Posted November 2, 2014 Share Posted November 2, 2014 Its not that big of a deal to put a nice pan and pickup on your car but there is so much Hype on the RB motors. Other than the sound thats about the only good thing about them. I think what your looking for a 2j would be better for you. that extra .4 litre is a lot. I went from a rb26 to a 30 and its a huge difference in torque. Granted i never get to drive it cause its always broke. RB= waste of money compared to the 2j. The way you use your car i would say go for that. Be careful with the thin head gasket depended on your pistons. Watch your quench zone clearance.

flatrate Posted November 2, 2014 Share Posted November 2, 2014 The Hype is real, their great engines. However any time you have an engine that was never in the united states it might require a bit more effort. From my personal experience and i have the little guy (RB25 lower end) it has been nothing short of awesome the last 4 years its been in my car.. The engine has made nearly 500whp all its life, and has been recently turned up to i'd guess around 700whp (street tuned on E85). Its never missed a beat and i'm not nice to it believe me. 8500rpm+ To ZTR, i don't mean to make you mad or piss you off, but how can you possibly knock these engines or discredit them when you went the most expensive route you could possibly go, and then all the related failures you witnessed where all caused by a collapsed hose, you put on it?? I'm not by any means saying the RB engines are superior to the 2J cause there not, however with a few modifications they are great. Anyone that wants long term reliability will build the lower end. Many people have pushed RB26's over the 700whp mark with stock bottom ends, and been successful, many have blown them to bits as well.. People have done the same with the 2JZ, not all of them survive. Look at full race and their R14 (S chassis with all R32 drivetrain) made 700whp on stock block and its road raced!! harder on an engine compared to any other racing if you ask me. Look at Rips going big with their RB30 powered R32 right now, its made 1100 (AWHP) at 24psi!!! thats insane power... I guess i just don't like to hear people knock these engines because in reality they are awesome, especially for an engine that was designed in the 80's. Do they have a couple weak spots?? Sure but nothing that cannot be easily corrected. Quote Link to comment Share on other sites More sharing options...
stony Posted November 4, 2014 Author Share Posted November 4, 2014 It is an awesome motor... Just not sure I can justify the cost to rebuild when a stock NA 2J longblock can make more then my motor. Especially when I can go to the pick and pull and get a motor for 150 bucks. Its gonna be a hard decision. Rebuilding a 2j cost just as much as an rb but I'm not talking about rebuilding.

stony Posted November 4, 2014 Author Share Posted November 4, 2014 If I do it, the initial motor will be a rebuild (bearings, HG, block decked 550 invested). but I will have 1 maybe 2 150 spare longblocks sitting just in case ;> Quote Link to comment Share on other sites More sharing options...
stony Posted January 10, 2015 Author Share Posted January 10, 2015 2J IDEA is dead. upgrade billet wheel for the t88 New billet wheel for the T88. still and old ass turbo but this should wake it up a bit i hope. Quote Link to comment Share on other sites More sharing options...
stony Posted January 10, 2015 Author Share Posted January 10, 2015 Should take the place of the 150 shot down the track for now. Will still need it to spool though. Quote Link to comment Share on other sites More sharing options...
05plsrt4 Posted January 10, 2015 Share Posted January 10, 2015 What exhaust manifold are you running? Quote Link to comment Share on other sites More sharing options...

05plsrt4 Posted January 10, 2015 Share Posted January 10, 2015 Does the manifold fit with no modification? Quote Link to comment Share on other sites More sharing options...
stony Posted January 10, 2015 Author Share Posted January 10, 2015 No I had to massage the shock tower to squeeze the turbo in and the wastegate pipe needed to be repositioned. Quote Link to comment Share on other sites More sharing options...

Glad to hear personally. I know 2J's are the rage and with good reason...but I guess I'm just a Nissan purist, I find putting anything other than a Nissan motor in these beautiful cars sacrilegious. (no offense to those that do... to each his own!) Quote Link to comment Share on other sites More sharing options...
stony Posted January 12, 2015 Author Share Posted January 12, 2015 IM not a purist.... well unless you count going fast... I will use whatever motor gets me there. Quote Link to comment Share on other sites More sharing options...
flatrate Posted January 12, 2015 Share Posted January 12, 2015 (edited) Be interesting to see how that wheel performs. Glad your sticking with the RB Edited January 12, 2015 by flatrate Quote Link to comment Share on other sites More sharing options...
stony Posted February 6, 2015 Author Share Posted February 6, 2015 24 valves removed, 24 valves hand lapped, 24 valves re-installed. another thing added to my list of things i don't want to do again. Head is off to get decked today along with getting the rotating assy in the turbo balanced. bearings are here, oil pump cleaned inspected and reassembled. Things needed, 1. Set of rings 2. Head gasket 3. Oil pan 4. Rods (I have a stock set but have decided i don't want to limit engine with rods) 5. Misc gaskets Hope to be completely reassembled by the end of march and ready for first TnT in april. Quote Link to comment Share on other sites More sharing options...

stony Posted February 7, 2015 Author Share Posted February 7, 2015 Jun oil pump. Gonna try the cxracing pan with some.mods and baffling. Quote Link to comment Share on other sites More sharing options...
stony Posted February 7, 2015 Author Share Posted February 7, 2015 Also gonna take some boost out of.it so it dosnt leave so hard Quote Link to comment Share on other sites More sharing options...
flatrate Posted February 7, 2015 Share Posted February 7, 2015 (edited) you run any extra restriction in the block? Ive been thinking on my next build to run the extra rear oil return/breather. Edited February 7, 2015 by flatrate Quote Link to comment Share on other sites More sharing options...
stony Posted February 7, 2015 Author Share Posted February 7, 2015 yep has a restrictor. also considering deleting the piston squirters. Quote Link to comment Share on other sites More sharing options...
flatrate Posted February 7, 2015 Share Posted February 7, 2015 yeah there is no real need for them with forged pistons. Or a drag race biased setup. I noticed your using a cometic gasket, i recently switched to an Apexi gasket after my cometic let go, defintaly a better design. I finally dyno'd my setup on E85, i never got even close to the timing you did!! pretty strange. im running about 17 degrees at 30psi Quote Link to comment Share on other sites More sharing options...
