Leave it all standard, replace the fuel pump and run a 75hp wet nitrous sysrem, will run low 13s to high 12s.

Will owe you $1600 in parts and with some guidance you can fit it yourself. Best bang for your buck.

Ive been looking hard at the Garrett range and I have come up short. It seems a small T3 flanged GT30 series are the way to go.

.63 or .82 exhaust housing and a .7 comressor. But from memmory these are externally gated, which in my case I am chosing to stay internally gated, for my personal reasons) This snail is rated around 600hp mark, so 250rwkw is achievable. Personally Id rather a T3 flanged custom garrett.

But for that money a TRUST turbo is probably the logical solution.

Your power figures of just below 250rwkw on a TD05SH would be achieved at around 18psi, as someone mentioned you really need more than 1bar to get a 20 boogying. Ive been in a R32 a couple of times with this setup and I was impressed where the turbo responded and the nice amount of torque it gave to a 20 still making it comfortable for the street.

If you are fairly serious racing or drift etc then the TD06 is the way to go. Although looking at trusts own figures you will find the 06's power curve shift a little bit far right of the graph for my liking, but none the less as people like ROY will tell you its worth it.

On my own car I am undecided, The price of the KKR430 is bloody inviting, but I know it will never be a trust turbo, and for a bushie they are damn responsive and dont suffer the problems ball bearing turbos tend to suffer when chasing the upper limits of the snails potential.

The last option is getting a special order GT3037 with a .63 exhaust housing, Ive seen this turbo on RB25 in standard trimming and a HKS S series one with some tinkering. They are a really nice turbo on the 25, I love the response of it but It ran out of huff at around the 300rwkw mark, although the rest of the car has potential, im sure it will get closer to the 500hp mark seeing it supposedly has a bit of a high flow jobbie.

In final thought about this snail It reminds me of the stnadard RB20 snail (comparing the 3037 on a RB25) its always on and when driven right the responsivness of the snail lays away issues of "LAG" etc etc, its just comfortable to drive or go for a run in :(

Welp, that is my rant, from what ive seen in my dealings and in my research that is what im looking at, my power figure desires are similar, so I hope you find my dribble amusing and possiably informative. Im gonna keep looking into it because I know how there is little market for a responsive snail that will make "good power" in todays world of LS1's that you wanna destroy.

I just got my hands on a gt30 with the .63 rear. Does anyone have any idea when it would hit fullboost and what sort of power figure id be looking at? Couldnt find any answers in the rb20 dyno thread sadly...

cheers

Dan.

Hey Dan,

I would love to hear how it goes (GT30 as in a 3037 yer?) Keep us updated if it goes on the car. And If you decide to sell it hit me up with an email!!!!!!

Umm yeah may be the same turbo Wheezy, I'm not up on the namign of turbos :laugh:, but my mate said he bought it new off Garret as a gt30. He was nice enough to sell it to me at a very high loss, and its still new :( Sure shows who ya good friends are eh :sick:

3800 eh, that should be fun in a drift car lol, ah well, will teach me how to keep the revs up :D Should do a decent burnout hahahah.

cheers guys, when its tuned(probably late dec, early Jan) i'll put the results up in the rb20 dyno thread :(

*I was talking about the 8cm ;)

Top stuff dude, Im hoping with my manifold being made that it will come on maybe a little earlier but even the TD05SH comes on around that area really hard.....Im content with it coming on just before 4K and revving to 8K FTW, nah in all seriousness, Im hoping to see a turbo that makes great power and has a fairly acceptable power band.

Im eagerly awaiting the results so I can finally put some money down on something.

      Coolant leak?

      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
