All I can say is Ben, I didnt compromise, I got the 3037:p and all up fitted with HKS wastegate, manifold and all associated pipework, ceramic coating and braded lines it will be under 6k.

Rob, have you spoken to the guys at Per4manz Turbochargine - they were doing packages fully fitted for 5k about a year ago - pretty sure they were very capable of the sort of power you are after.

the gt30 seems very popular for the garret turbos. The gt35 is far to big for street. You can however get places like ray hall to change the front and rear wheels so your turbo does spool up sooner.

going for a custom job means that you get exactly what you want.

Going for a brand name you cant really go changing it as it isn't really worth it, as the cost u pay is a fare bit.

and remember you got for the garret turbo over the name brand you are getting it brand new, not second hand.

i'd also like to know what the gt30 goes like on a rb25

Has any one got any experience with these on the RB25 i.e where they make full boost etc?

with that 1 u need to buy adaptor plate, ext wastegate and oil line kit!

The greenline kit is nearly 7k, the rx6 kit is a bit cheaper (by about 1k). I actually got the turbo from www.fvej.com, also got a hks wastegate for 290aud second hand in perfect conditon.

The rest is being custom made. I was supposed to be putting the car in last sat to get it all done this week, but the guy is sick so I'll have to wait.

Wouldnt be able to get a proper power figure up for a while anyways, as I have a head gasket and cams coming from japan, but they are on back order, plus I have to get my injectors and fuel pump fitted and a tune, so it will probably be a while yet:(

If you hunt around, you can get the bits cheaper than buying a kit - still waiting for a final figure (dont like setting price for custom work until its over - that way you dont get corners cut:) ) I have been given a rough price though - acutally be closer to 5 than 6 fitted - so you can save a quid.

With regards to fitting a GT30 500hp Unit on a RB Motor.

It normally comes off the shelf with a big comp cover and an externally ‘gated exhaust housing BUT….

I can do it with a .63 integral wastegate and a TO4B .60 comp cover that is a bit smaller. It will then all bolt on to your manifold and all is sweet.

Price is $2695.

If your interested I have been selling a lot of GT28’s with bigger (500hp) comp wheels fitted, these come integrally ‘gated and will be more responsive due to the smaller turbine wheel than the GT30. I have adapter kits to go from T25/28 to T3.. pic attached. Flange adapter kit is $150, GT28 500hp hybrid is $2295.

As I am chasing a turbo for my RB30 soon this is the reply I received from Tim @ Horsepowerinabox.

Joel, for a 3 litre, these turbos (from Per4manz in WA) have been used with huge success on 2jz motors, and very good on rb25 too. I would have got one if my 3037 didnt come up at the right price :) Basically a GT35 with GT30 turbine housing, externally gated

Most of the turbos we use come on boost @ 3-3500rpm for the serious hp applications or even sooner for street combinations.

 

Last 2 rb25's that I have done have made 320hp @ 1 bar (std engine) and 400hp @ 1.3bar (modified) at the wheels.

 

Can only supply propriety compressor maps and these don't have much detail (surge limits & max flow only) The gt35s flow @ around 80% efficiency @ 1 bar depending on a lot  of variables

 

Cost of one of these is $2477 inc gst

Edit: those adaptors look like turbulence city

      Can't you put the pistons to TDC and then do the valve seals? Or will the drop down too far to pull them back up?

      Replacing turbo water line - any recommendations or advice?

      By sunsetR33 · Posted

      One thing I can tell you is, do it properly the first time. If you encounter unexpected problems just let the car sit for a week or two if you have to get some other parts or figure stuff out.  I'd have said go and use as many OEM parts as possible but since you want to change the turbo later on a custom kit is probably the better choice. Since I have no experience with RB25 just compare parts diagrams and images before buying a line kit and it should be easy to see if it has everything you need. Amayama has very good parts diagrams and part number lists, that is what I used a bunch to figure out what I might need. And don't forget to plan ahead and possibly renew other stuff that's easy to get to while you're in there doing the turbo lines. Happy wrenching

      Update 4:   Hi all, good news. Engine is running and all the gaskets and seals seem to be working as intended. No leaks so far, even the JB Weld seems to hold. I flushed out the old coolant a few times and put in fresh coolant, not Nissan stuff, I decided to try the Ravenol Protect FL22, they claim it works for a wide variety of JDM cars and the opinions on it by some people were pretty good. And it has the nice poison green color! And man am I glad I bought a coolant system tester earlier this year, vacuum filling works wonders on this engine. I can definitely recommend this to anyone still doing it the old school way. All you need is compressed air supply. Will have to do a small test drive as soon as I can, I removed the gauge cluster again as the tacho needle was still bouncing around a bit but it was much better than before already.  I also found some cracks on all 4 tires inner and outer sidewalls. Apparently these tires should 't be parked on for extended periods or be kept under 0 degrees during storage, which I did not know. Clearly the previous owner didn't look into those details either, he probably bought them just cause they are cool semi-slicks. I'm just wondering how tf I am supposed to reach 30-80 degree tire temperatures on the public road consistenly, these tires were never going to work for my use case. I'll probably order Continental SportContact7 ones as these are the best allround summer tire available right now and I don't think I'll need anything crazier for now. Do let me know if you have experience with various tires and which ones you recommend.

      Not going to pretend I didn't do a bit of junky work this time around, but mostly due to the fact that some things I am not willing to spend days fixing right now, like wiring. I try to do most things properly the first time around.
