Martin would it be possible to have an overlap copy of the V8's 400+rwkw power torque curve and maybe your Soarer, a few r33's with different power levels and a couple of R32's thrown in their?

or

If I can have a copy of the above runs I will overlap them and make a post here ?!?!

Joel, HKS 2510 turbo @ 1 bar, FMIC, 3" exhaust, Bosch pump and re-mapped computer

Check out this dyno chart. This is from the weekend, a good comparison between Grepin and Freebaggins RB25 and my RB20. Just shows how much 1/2 litre makes a differance in the midrange

note - I have blurred out our rego numbers just in case there are theiving bastards browsing the forums for quick cars, but have marked which one is what

Just looking at the AF's Chris it looks like yours was running quite a bit leaner in the mid hence the power loss possibly?

I remember when mine was tuned similiar with similiar AF's it lost heaps in the mid range.

I found that running the mid a little richer (just under 12) made best power.

The PowerFC looks like it has a very good power curve and also AF' Ratios. hrmmm

Yeah, not to sure Joel. I just put it down to being 2L v 2.5L with variable inlet timing. If I compare the dyno chart from when it had the stock turbo on, the mid-range is virtually identical.

Going to use a electronic boost controller instead of the bleed valve to try and fill the mid-range in a bit.

Perhaps Martin could comment on this, as he tuned it and would have a greater understanding of this then I would?

I found with the EBC it actually came on to boost a little slower but was more controlled compared to the bleed.

I.e the Bleed felt quicker because it would spike up really quickly then boost would slowly drop off, the top end would flatten out where as with the ebc it still comes on hard but it is only hitting say 1 bar instead of 1.1 bar however the top end is better due to not loosing boost.

Might be different with the 2510 unless that drops boost up top also with a bleed?

Nah, doesn't drop off at the top end. I just want to see if it will get ti th 1bar quicker than it does currently

I'd like to get a EBC anyway, so I don't have to fiddle around under the bonnet if I want to run less boost. Wil be good to see what differance it makes on my car

OK, it's on, The "How Crap!" Challenge:

Gotta beat Chris32's RB20 power level.

Gotta beat MattR's RB25 powered power level (no it doesn't help mate).

Gotta beat Nightcrawlers 400m elapse time.

Gotta beat Martin's 1Jz power level.

....man-o-man. Give me some time & $$.

Freebaggin.

P.S. Also gotta keep grepin at bay!

      RB25DET with solid lifters - which cams ?

      By GTSBoy · Posted

      I always wondered how you were supposed to buy a set of 24 buckets and somehow magically have every single one of them yield exactly the desired clearance. I would have thought you'd need to assemble a cam with either 12 "sample" or "example" buckets of known top thickness (or a single such sample/example 12 times over!!) measure clearances at every valve, and then do the usual math to work out what the actual "shimness" of each bucket needed to be, before buying the required buckets to make up he thicknesses that you didn't have on hand.

      RB25DET with solid lifters - which cams ?

      By TurboTapin · Posted

      I now seem to be limited in power due to my rev limit/hydraulic lifters in my built RB25. I'm looking into converting over to Tomei solid lifters. Question for anyone that has done the conversion. I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  I don't know where I got this idea, as so far I see no mention of this in any of the Tomei documentation. It just states I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!? There's no way it's that simple, I must be missing something?

      Why am I hitting a power wall with my stroked RB25?

      By TurboTapin · Posted

      I couldn't agree more. I should have started from the get-go with a NEO or solid bucket conversion. I started looking into converting over to solid lifters yesterday. Now for some reason I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  But I see no mention of this on any of the Tomei documentation. It just states that I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!?

      "Cheap" bolt on turbo on RB25DET NEO

      By Kapr · Posted

      @Murray_Calavera iam just considering options 🙂 of course it is very expensive so that why i ask here 🙂  @joshuaho96 I looked at that GCG hybrid(i remember looking at it few weeks before) So this is "that" hybrid where i send them my turbo and they upgrade the inside to Garrett stuff and then they send it back. It cost around 1200-1300 USD which is FAR cheaper than the HKS and it is what iam looking for(i just do not have experience like this...to send something off to "upgrade" ) @tylink720 that is like 150 USD turbo no? 😄 I dont think i have the "ease on my mind" with this kind of turbo. I just put over 7000k USD to "LINK" up my engine...dont want to blow it up with cheap turbo 😄     EDIT: https://www.cj-motor.com/gcg-turbo-charger-for-nissan-rb20det-rb25det-high?srsltid=AfmBOooVeOZ6CZ6r1AIv5m-KPaa6BvudIPJTY8LW78khkd-gQlsaCht9 I looked at this and it seems ok? It is that CGC hybrid and it costs around 1250 USD (with back shipping). Do any of you have experience with this hybrid on NEO turbo? I quickly look thru the forum/web and it seems very good.
