The R32 RB25DE VRS kit is around $275.

It includes all top end gaskets consisting of inlet manifold gasket, plenum gasket, exhaust manifold gasket, rocker cover gaskets and valve stem seals. There may be more thats the most important one off the top of my head. :cheers:

If I was to buy JUST the valve stem seals from Nissan they wanted $330.. lol

i have a question for you guys i have an rb30 block and a rb26 head i want to put them together is it possible if it is how do i go about doing it and where do i source the parts to do it thanks alot.

dude... you've got 99 pages here which pretty much give you the ins and outs of exactly how to do it. There is also a guide floating around (i think Cubes did it). Infact there is a link in his post above this!

I thought I'd update ppls..

I've since noticed a surge issue around 1800rpm. frown.gif

Loading up say 4th gear at 1500rpm starts to see boost quickly then it goes flat and the turbo sounds strange, if I hold my foot in to it the turbo starts to make a really strange noise (almost a popping noise) then the car begins to jerk around. nasty pasty. :)

I have never actually held my foot in to it when it has that flat feeling so I haven't heard the popping or felt the jerking before. Never again will I do it. Sounds really bad.

Not to worry, its never really in that zone anyhow. :cheers:

A good excuse to pull the little terd off. :D

Welcome to the world of compressor surge:cheers:

thanks alot for your help, wha tkind of power have you seen this conversion produce, i am living in the united states and there is not alot of people that do these kind of conversions so i jus wanted to try something new, again thanks alot for your help guys.

What, you guys had enough of buying every sr20 on the market and driving the price up for the rest of us? Want to move onto something else to overvalue do ya?

(not that i won't sell you a rb30 short motor...)

guys...

if i through a rod in my 25det could i just bolt on a rb30 bottom end?

would like to keep compression same maybe a bit lower...

im running 18psi through standard motor and i know it will fly apart soon, hahahaha

any help would be great

thanx

This would have to be one of the longest threads I've ever seen and by far the most useful.

Cubes and Sydneykid have been saying for quite some time that cams should become before upgrading the plenom, in particular TOMEI 256 cams. I have a Rb25 head with VVT that is ported and polished (mirror finish).

Has anyone used these cams in a 25/30 and has dyno results to show?, I'm interested at looking at the mid range Hp and Torque.

i am sorry if this has been asked but can you use SR20 pistons when building up a rb30det?

and does anyone know a good place to get rb30e pistons from.

thanks

I've read about using sr20 pistons in them before, Blue r33 with 26 head 30 bottom that was in nzpc a while ago was using them. I'm still not sure why anyone would do this in preference to using forged 30 ones, needing to buy two sets of sr pistons bumps the cost up a bit.

A bit of the topic, ive got a rb30det in my R32. Has a stock bottom end with a R32 RB25DE head. Ive got an old school t04 on it with a smaller exhaust housing. Its running out of puff around 300rwhp.

Just wanting to know what turbos u guys are running and the power your making, and how the driveability is with them? Im after something that will produce 450rwhp with a good power band?

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
