hi,

I got the rb25det i've been wanting for so long and put into my car, But I am having some problems boosting above .6

I have a walbro pump and sard regulator stock injectors and everything is stock the turbo is stock too

My electronic boost controller is the Greddy E01, I've tried all sorts of settings but the boost wont go higher then 0.6 before it starts going burrrrrr and very hesistant boost cut or some thing like that. it's fast until it gets really close to the 0.6!

I have set the setting to about 0.55 and sometimes i get micro hesistations! at .55 but not many as i keep rolling the setting lower until it is smoother! but the largest problem is the boost! I wanna try 0.8 or even 1 bar but cannot go that high.

the engine was imported from japan and has very low km/s about 20-30,000 kms had the ports polished and all that! and put the new gasket so it sound great!

anyone can tell me stock engine is okay at 0.8-1bar? and what are your ideas?

thanks guys!

Shaun

Agreed, shouldn't be stuffing around with Fuel Prerssure Regulators without a tuned ECU.

Not worth the trouble anyway, take it off and sell it.

Put the standard FPR back on and then play with your boost and see what happans....

Might clear it up

    • Hi...so a "development" here aswell The swap is "done" and car went "test drive" BUT it seems the clutch(maybe gearbox?) is a little bit sad? I bought this clutch kit https://justjap.com/products/xtreme-heavy-duty-organic-clutch-flywheel-kit-nissan-skyline-r31-r32-r33-push-type "Problem" is that the first gear is hard to put into and it seems that the clutch is not disengaged. It was not the problem with the old clutch...(or like sometime the first gear would not get as easy specialy when the fluid was cold) So? Can it be like...bad "install" or is the clutch wrong ((it should not have been) i done research to get the right one) Or is this "normal" with new clutch and needs to be break in? 
    • @Duncan I can try  and thanks i did not thought about VIN and part numbers for 33/34. @GTSBoy yeah it looks like iam gonna do that  
    • Forgot to include this but this is the mid section of my steering rack that looks like it has a thread/can be turned with that notch mentioned in the post:
    • Hey everyone, Wanted to pick some brains about this issue I'm having with rebuilding my 33 rack (PN is 49001-19U05). All of the tutorials/videos I've seen online are either R34 or S Chassis racks which seem to be pretty straightforward to disassemble but this process doesnt carry over to my rack. Few of the key differences that I've noted The pinion shaft on the other racks bolt on with 3 torx bolts: Whereas my rack bolts on with 2 allen head bolts: These changes are pretty inconsequential but the main difference is how you pull the actual rack out of the housing. The other skyline/s chassis racks can be taken out by tapping the rack out of the body with a socket and it just slides right out. I'm unable to do that with my rack because there's a hard stop at the end that doesn't let the seal/shaft be tapped out. Can also see a difference in the other end of the rack where mine has a notch that looks like you're able to use a big wrench to unthread 2 halves of the rack whereas the other racks are just kinda set in with a punch. My rack: Other racks: TLDR; Wanted to know if anyone has rebuilt this specific model of steering rack for the R33 and if there were any steps to getting it done easier or if I should just give this to a professional to get done. Sorry if this post is a bit messy, first one I've done.
    • I would just put EBC back on the "I would not use their stuff" pile and move on.
