Thanks for the info. Unfortunately with RB30 conversions the belt tension is not the belt tension due to the fact that you have two tensioners :/. What do you mean by they will be 10 belt steps apart from each other?

That is the "method" I was using lol. Not to mention that to get the dots on the cam gears to line up the belt has to be horribly tight (RB26/30 conversion). So I've slacked it off and the exhaust cam is out by about half a tooth. Think that could do it? I'm thinking that may be the next c...

It's also quite dangerous because load isn't going to where it's supposed to so AFRs are in the 13 range at full boost. if the tune is good, it shouldnt be anyway. Check fuel pres on the load, fuel filter, fuel pump. Maybe you have problems with fueling. I don't understand what you mean. If I scale...

I reused them. I only replaced the bearings. I suppose I can do a comp test but the symptoms are not indicative of low compression. This is the 3rd time I've reused the rings. Every other time compression has been 150 across the board.

Guys I cannot figure this out. Cleaned the MAF, checked for unusual boost leaks. Nothing. It builds boost and power ramps up till about 3500 or so, feels like its gonna go like stink and then boom power just hits a wall. It's also quite dangerous because load isn't going to where it's supposed to so...

I'm certain it's fine. It's building boost fast and holding 15 psi.

Guys I'm completely at a loss here. I rebuilt my RB26/30 due to spun bearings. Put it all back with stock components. While apart I changed/did the following: -New ACL big end and mains -Had the injectors cleaned and tested -Cleaned the head with new seals / lightly lapped the valves -New plenum gas...

I find myself with the search often being frustrating and somewhat useless, as such terms as "knock", "sensor" and others which are useful often receive the "search terms too common" error and you get nothing. If those terms are so "common" as it's saying, whi...

This is all fine and dandy (and I must admit I am thouroghly confused lol) but how do you explain the fact that two seasons ago I was using this exact same setup and I did not have this issue? The only thing I changed was my laptop and hence new software. I didnt get much of a chance to tune it last...

Nice setup!!! That should really get some results! I don't have a definite answer to your Q, but I use the same CAS simulator on the bench for both RB20 and RB26, so that's a positive sign. I gotta go visit a local workshop that does a lot of RB stuff this arvo, so I'll ask them about RB20/26 CAS c...

My project has gone like so: 2009: RB20DET/Nistune 2010: RB30 w/ RB25DE head w/ RB20 sensors/Nistune. Upgrade 740cc z32 MAF, 6262 turbo. 2011: Tweaking. 2012: RB30 w/ R32 RB26DETT head w/ RB20 sensors/Nistune? Will this work? I think damn near everything should line up. -Injectors are top feed; impe...

Well i took your advice and put in another cheap, yet better designed intercooler, and WOW did it make a difference!! For anyone using a same side entry intercooler on their RB, ditch it if its a horizontal flow for favour of a vertical flow!! It builds more boost/higher load for longer but now it i...

Matt, any new developements on this?

Voltages coming from that 0-5V white wire are rock solid within .00 and only fluctuate by +/- .008 or so So you are saying here that the Nistune default DLP values (mapping DLP volts to Nistune volts) match the multimeter output volts within 0.008? So the look up translation appears to be correct t...

Oops, couldn't attach the debug. Here it is. PLLLLLLLEASE give me something to go on here! It worked just fine last season!

Omg it's too big. I went as fast as i could but it still came out to 20 MB :/. Ok I RAR'd it up for you.
