Within the next 2 months I'll be doing a similar upgrade with 2530's, only difference being mildly ported head, HKS 264 inlet & 272 exhaust cams, dumps, no cat & pod filters. Its currently putting out 225rwkw in stock trim on 1.0 bar - should be interesting comparo to meshmesh! I'll post the final results in the near future.

I saw Simon last night and he looked as giddy as a school girl! lol

Great stuff mate I have to say. Will be interesting to do the back to back comparison with JAGR33 when his work gets complete in the next few days by the same guys to see the difference (Im not going to spoil it Jack! :) )

Now mate all you have to do it get the 34 and do it all again! :D

Yeah I'm interested to see how my car will go aswell once its done... Although it will be dynoed on Ice's new dyno by then.....

Maybe we'll have to get meshmesh to have a go on the new dyno aswell, for the comparison to be more precise....

Cheers Andrew for not spoiling.... :D

Hi Jack... Gerald seems real excited about your car and said the same thing about comparing the two. I believe the dyno should be up and running as very late this avo, so once the boys are ready I'll drop it in next week so we can compare.. So glad to have the car back now it's your turn, but I'm sure you'll be rapped.

PS: Be careful what you say infront of the snowman, he's on a mission of attack... I hear his going for the same set up as Leewah's but even more power... I heard him and gerald talking numbers like 700kw at the rears.

Yeah well I'm still awaiting parts from Japan, so won't get done for atleast 2 weeks now... :)

Yeah the guys were saying that you had quite a smile on ur face once you'd taken it for a burl....

Will be more than happy to do a comparison, as we both have standard engine/cams/manifolds/dumps/ecu/boost controller/catchcan etc.....

So Snowy's on a mission hey??? Got sick of seeing all these GTR's at Ice getting turbo upgrades??? 700rwkws??? :D

Here's mine from last Friday, same sought of set up but with 2540's.  This was on 1.2bar. (With HKS 264 cams)

Hi GZ,

That's interesting, can I ask you a few questions?? Thanks :D

[Disclaimer - I know that dyno's are a close indication and vary substantially according to many variants, and only using this a guide:)]

Just looking at your graph, it seems overly laggy, is this true & how are you finding the 2540's? Have you driven one with 2530's?

meshmesh, great result.

On the thing of dumps - I understand fully if you are 100% happy with your result, so I aint being smart.

I found huge gains in the exhuast side.  back pressure really started killing my power above around 290rwkw.  I upgraded to a freer flowing exhaust and brought boost on around 600rpm earlier, turbos were more responsive and I picked up top end.

Have you thought about getting the cat removed - this too can really crispen up the throttle and bring boost in earlier.  And as for dumps, well there again I think you would find more response and less lag.  For a street car, if you can get good response in by around 3-3500 its just about perfect.

Anyways each to their own.  you have a great result there.

Hi Steve,

I remember the drama's you had, and thanks for that thread, it's one of those threads that just sticks in my head.

Firstly, like 99.9% GTR owners going for similar upgrades, the dumps were definatley on that list namely HKS, & the IC. Then SK & markr34gtr said stuff the HKS, Trust is the way to go.. So I head off to see the boys at ICE had a chat... Not Once, Not Twice... Probably about 10 times seriously, I asked the same question each time "Are you sure about sticking to the stock dumps??", they're reply was always the same "Yes, we see very minimal gains for the money... "

So I figured a few things:

1. By doing something a little different to everyone else, could be a comparison for the forum & others to see if and what difference they really make.

2. If I felt that I was not happy with the cars performance then I could always fit the dumps later.

I guess my thinking was similar to those who spend BIG $$$ on fancy plenums, manifolds for nothing when the stock units are more than [keyword]capable. I spent a bit more time today watching the boost carefully, and what I call boost [sorry no offence ferni :D] some may argue, but I think boost is when you feel the BANG, and not so much the start of spool... If I take the latter my turbos start to spool from +0.00 @ around 3800-4000rpm, however you really feel the BANG around 4600-4900 all the way past redline.

But I'll probably wait and see when mark gets his trust pipes and see his opinions. Either way the car is going back for some minor adjustments next week, I'll keep yo'll updated.

PS: INASNT or any using the HKS EVC.....Need some help please

Say you've selected either high or low setting, if you click "Mod" it goes through other functions in that setting. You get to a function that allows you to set between 50 - 150??? what does this do?

Yes i am using a EVC 3. I havent really played with the evc yet but i do have the manual for it. Nige should know all the settings as he told adviced me to get a evc as they are the best ebc u can get especially with an external gate.

meshmesh - ahh i see, not sure what is defined as boost then, guess i need to take one of you guys for a drive so you can tell me when it comes on...

as far as i can see i nealry always get the kick(which isn't that hard with 1bar stock turbos, its more of a gradual thing in my car) at around 3.5-4k rpm

    • Will have a look at that. I cant see any leaks 
    • Put another overflow bottle (ie, a 1.25 coke bottle or similar) under the overflow hose and see if it is being pushed out there or if it is disappearing into the engine.
    • Staring on a stand is no issue. You just have to wire everything up, give it fuel and cross your fingers that the stand is robust enough. Arranging the inlet plumbing is often the hardest part, without any surrounding structure to hand some of it from. No need for coolant if you only want to run it for <1 minute. As to the gearbox - I think the little Aisin box is a bit stronger than the other small Nissan boxes that went behind SRs, but I wouldn't be too keen to test its limits with the torque of a boosted 25. I don't know if you can retain the box and the tailshaft. The box won't connect to the RB without an adapter of some sort, which is either a plate that will push the engine forward (which is not good for fitting it into the bay's available space) or push the box back, which messes with the box position and tailshaft length - OR - cut and shut work on the bellhousing, which is a long way from "least modification". I'd be buying a new 370Z 6 speed or similar, doing what has to be done to that to make it fit RB (ie, cut and shut bellhousing) and the requisite tailshaft custom/mods.
    • Hi Everyone I am from West Pennant Hills in NSW. Been too busy until recently to attend to my RB25DET Series 2 engine until recently. I am planning to stick it into the S15 shell at this stage, unless a nice SR20DET turns up... For now, i am going to try and get the RB25 running and working well then decide what gearbox to use. My preference is to retain the SR20DET  6 speed gearbox and tail shaft to retain as much and least modifications as i can avoid. I am an old guy and won't be doing any heavy drifting so i don't need a bullet proof gearbox Does anyone have experience with starting the RB on a stand? I got everything setup as much as I can with the info i can find... endless searching and videos on Youtube I would be great to get some pointers Cheers Songo
    • Hey all, Recently have had my s1 r33 gtr serviced and noticed my coolant reservoir was topped up to the max line. Took the car out for 1 yesterday and noticed today the reservoir is completely empty.  Any ideas? Radiator is full
