yeah had the same sort of issue realy running 3 turbo back exhaust, link g4, fmic, 400cc injectors 25turbo @ 13 psi and was hoping for 190 to 200rwkw but only ever made 172rwkw. so 188 i would consider good IMO

Ok so the r33 25de 4wd motor will definatly bolt in to my rb20det 4wd sump?

So in saying that it would be possible to bolt any 25det/25de/26dett motor in to my 4wd sump, dosent matter weather its a 4wd motor or just Rwd?

Will a rb25de 4wd block bolt to my rb20det 4wd sump? ive been told it will, any other comments on this? thanks

Ok thanks for that one white, so with the diff ratios basicly i can keep using my excisting diff (center and rear) how ever the power is going to spin them up to quick so its in my best interests to upgrade to for example a stegeas center and rear diff?

Ok so basicly the rb25det 4wd motor from a stagea will bolt strait in to my r32 gts4? And the same goes for the rb25de 33gts4 motor correct? -Yeah sorry Kiwirs4t i was meaning i just needa get the cable! im in the know about what the link can and cant do. -sorry discopotato03 i dont have 20 to 25k to spend on a gtr, nice thort tho:) Hmm seems the neo gts4 motor is harder to come by. ill be hunting around for abit id emagine

Im running a linkG4 at the moment, I know i have to get a VCT controller wired up to the link as ill be utilizing the VCT, more my quires are focused at is fittiment, diff ratios, mechcanical drive line and 4wd fittment. im using uprated coil packs and have been told that i am able to runn these on the rb25de - but they would not fit if i was to use a stock rb25det motor>?. deffinate knowledge from people who have done the conversion/Knows RB series engines inside out(what fits what between models) - would be much appriciated!

Hi all, basicly im looking at doing a motor conversion on my gts4 early early next year - starting to prep my shit soonish Just wondoing if anybody has down a conversion involving a rb25de 4wd motor out of r33 gts4 - and sticking it in to there r32 gts4 im wanting to scrap the rb20, and seriously looking at doing a rb25de+t Just wondoing if its simply a bolt in conversion, or am i going to have to look at diff ratios etc? basicly info i need to know before me and my mechcanic get down to bizzo! Cheers NS.

New zealanders dont run cats. Its running safe as in terms of being lean or rich Long story short it made 155kws with stock ecu, then i added a link g4 and larger injectors to keep up with the blower and it made just over 10kws more 165 170kw he told me the moter allmost seemed to respond like a non turbo rb20de higher compression motor.

Yeah those were the power figures qouted by my tunner atleast 180 to 190kw id say anywho, its only putting down around 160ish kw at the moment as he tunned it back to 12psi...

hi all, I have a suspected timing issue on my rb20det basicly its not making the power it should be and is over all down on power mods are 20det motor 112.00kms reasonble low kms keept in good condition 25det turbo good conditiion dsr uprated coils 370cc ca18det injectors all flow test pre install walbro 255lph fuel pump FMIC kit link g4 gts plug in to controll everything. everythings been check over to made sure its all in check arfter a full complete tune its only just making 170kw at its very peak(13.5psi) my previous power before the ecu was 155kw my tunner said its knock limited when tunning upwards of 170kw and possible that the timming belt is out one tooth casing the motor to basicly not make the power it should be making with thses mods (190 to 200kw) all tunning was done on a hub dyno im drawn away from it being the turbo as its dosent blow and smoke what so ever and holds boost all the way up the rev range your thoughts? if i take the cambelt cover off is there any simple way i can confirm that its out one tooth? looking at marking etc? thanks
