Man that looks hot as, I wish i had your car lol. Keep us updated.

Yeah the only reason i ask is because its a good upgrade for a RB20 i heard and i have a RB20 atm and having the 30 being build (well getting parts together) and just thought i could put them in my RB20 for a upgrade while i wait for the 30 then put them into the 30. But if i have to machine the 20 head then the 25DE head then theres not that much point as i dont want to do much to the 20.

But once you do the solid lifter conversion then wouldnt it be a good thing as it has higher lift?

seeing as though RB26 cams fit into RB20s, Do RB26 cams fit into R32 RB25DE's?

Custom is best. Go some where and they will make one better and cheaper than shit your just paying for because of the brand name.

Question about cats allways comes up. I just want to know a good brand with a good price, not something for crazy power as most people dont have over 260 kws

No you can get cams that keep VCT. But not very big ones, so once you get to a certain power level VCT has to go. Im pretty sure any more than 400 HP then thats where VCT is about dead? I havnt heard of anybody keeping VCT at 400KW, thats a very big number.

Hey your on SD too. What do the cops think of your car Looks hot dude.

Just the same rear housing.

From a RB25 :S

lol i like that.

Yeah i think i just have to live with the fact its not going to work lol. Is there any stock turbo that wont be to bad for the RB30 till i get another one. Like a VG30 one over the RB25 or some others?

You think if i be nice to it, it will last longer?

Yeah i have a Mines ECU in the RB20 at the moment. But i think its best if i get some GTR injectors (when using the R32 RB25DE head?) and a AFM and tune it wit the stock ECU (not myself obviously) The car I have is a 180sx with a RB20DET with a RB20DET box behind it, now i know its ok for the 20 box to go with the RB25 as its a lighter car than a 33 and such, BUT how long do you think it will last with the RB30? Will it be ok seeing as though it is in a 180sx? (only for a short amount of time.)

stroker sounds nice! So ill take out the prepping the stock rods i can do that later with more power. For what would i need just to get the thing running and in the car without anything fancy does this sound right: 1. RB30E S2 block 2. R32 RB25DE head 3.Head Gasket (But what one just to get it running?) 4. Inlet Manifold and Plenum (RB20DET) 5. grind down the water galleys 6. stock RB30E Pistons (so for now the CR will be decent) 7. full length crank collar installed (do i need to do this?) 8. Engine Bearings 9. Oil Pump RB20DET (just to get it on the road) 10. Water pump & Thermostat (RB20DET) (just to get it on the road) 11. Power steering bracket 12. "Use a longer piece of oil resistant hose for the oil drain pipe" - will i have to do this with a stock RB25 turbo? 13. Relocate 33mm of tensioner studd and Cam Belt 14. RB20DET ECU - remapped And that should get it running so i can drive it around for the time being (i wouldn't be driving it hard.)

Yeah i think i will just go with the R32 RB25DE head. I created a list of everything i need, does this seem right: 1. RB25DE (R32) Head 2. GTR valve springs 3. Head Gasket 4. Inlet Manifold and Plenum (RB20DET) 5. grind down the water galleys protruding lumps that run from the front to the rear of the block. 6. Short Motor (RB30E Series 2) 7. RB30E Pistons (~8.2:1 CR) 8. Prepped stock rods 9. full length crank collar installed 10. Engine Bearings, (Genuine Nissan Bearings or better?) 11. Oil Pump RB20DET 12. Water pump & Thermostat (RB20DET) 13. Power steer bracket grind the lug flat so the bracket is able to sit flat on the block. 14. Use a longer piece of oil resistant hose for the oil drain pipe, you will also be required to bend and stretch the oil and water lines to meet with the turbo. 15. Gearbox RB25 Series 2 16. Relocate 33mm of tensioner studd 17. Cam Belt

What did you end up going with?

White 90` R32 Gtst – Drift hack 490rwhp @ 1.5bar What you got in it

So if i dont go with the VCT head then im not missing out on much? Because it seems like if i go with the R33 RB25de VCT head then i have to get the different set of side feed injectors, different ECU, sensors Loom, etc Bit if i go R32 RB25DE then i can use loom, ECU, Manifold, exh manifold, sensors etc. The only thing im worried about is low down power, Would i see much of a difference between a RB30 with VCT and without? Im aiming for around 400 hp to 500 hp max, So would i most likely have to get cams in there anyway to achieve this so would going to all the bother of getting the R33 head on there be pointless?

hello...

Yeah i have a RB20DET in the car at the moment. But i can sell / swap for RB25 parts that i need. But if im doing it now i may as well do it right from the get go and keep VCT, as if i dont it would allways be on my mind. As R32Abuser said about sensors and what not, Will keeping VCT make it more expensive to upgrade? and is it true that you can use a remapped VG30DET ecu as it has VCT?

oh didnt know that, seems a lot easyer to go the R32DE way lol. what would be the springs to use for the RB25DE VCT head?

Yeah i would definitely get the GTR valve springs eather head. At what HP does VCT become pointless? due to other mods etc disabling it.

Yeah i want the whole down low response thats why i want the RB30 haha Yeah i read that RB30 pdf, was a good read. Just thought i would ask to be sure as i dont want to go out and buy a RB25DE VCT head then go damn its to much work. So the RB25DE with VCT head goes straight on pretty much, just have to set up and drill a few spots for the VCT to make it run, other than that its the same as the R32 RB25de non VCT head from then on?

Hey guys I been looking around and reading about the best way to make a RB30DET by looking at other builds and info on this site etc, i have 3 questions where i am just stuck on as i don't have enough experience. I know the R32 RB25DE non VCT will go straight on., But will the RB25DE with VCT go straight on as well? (bar the fact that you have to drill some things to the block etc for VCT to work) To me with not much experience in making RB30s etc this seems like the RB25DE with VCT head Vs the R32 RB25 non VCT will be a lot more expensive is this true? as i wont be doing it myself. and lastly is it worth the trouble to connect VCT? I am wanting to run twin turbo system on this and im not sure if VCT is even worth the fuss? Thank you.
