Im gonna run 10, thats my absolute limit. Im running 6.5 atm, car spools nicely. Its weird having it on boost at around 2200rpm, then thinking, gee this is pulling hard, then that weird ass top end power comes on and your off twice as hard. Great fun

Yeah I had the same with my car, it was bizzare...the top-end was impressive

  • 5 weeks later...

For anyone interested in doing this conversion, I made 210rwkw and 475nm on Dr drifts dyno today @ 9psi with stock injectors, stock ecu & stock R31 fuel pump, cooler and high flow t3/4

666Dan, how much boost was the turbo making from off idle?

I've worked on a few RB25DE's which have had RB20 turbos fitted to them and they were practically making boost when idling. Massive torque down low but runs out of top end very quick... One of those cars now runs a fairly insane turbo/setup (still high C/R for response), makes about 300 rwkw or so, that was done nearly two years ago and its still going, really needs good tuning to keep them together....

hey man, i wanna turbo my r33 rb25de what computer do i run, some ppl say rb20det and some say rb25det, some say the rb20det wont work with the vvt etc and the rb25det is too hard to tune, im confused i can get all rb20det parts real cheap but dont wanna do it unles i know what ecu will plug in and work, can i get away with just a std turbo ecu and tuning and no link or safc etc as im on a tight budget, only want to run stock std boost...

cheers guys

my sugestion is if your on a tight budget then wait until you got the money to do it properly, you never know what might go wrong and end up costing you shit loads to rectify, as for ecu, i would not sugest any standard ecu as it will not be safe to drive, possibly a standard TURBO ecu with a piggy back, but aftermarket is always best, as for r32 ecu it will work but i think something has to be done to it to make it work ie some pins have to change or somethingh and it will need to be re-mapped and you will need an aftermarket cam controller, dr. drift suply and fit r32 re-mapped ecu's with cam controler for around the $1300 including dyno time, or you could spend the extra 500ish for an aftermarket unit tuned,

As these guys have said, if you're not after full tunability, the stock ECU is fine..generaly the tune on it is quite well suited to the higher compression. Stick and SAFC/emanage on it if you want to adjust a bit more.

I have just finished my turbo conversion in the uk and made 310 bhp and 275 lb/ft torque at 9psi would highly recomend this conversion to any one . Thanks for the idear and info 666DAN with out this forum and your info i would still be driving a 200ish bhp A/N and wanting more power . So thanks again :O i have added a pic of what she look like .

hey mate wat mods do u have in ur car to make that sorta power?

Hi mate i have a 100mm front mount intercooler and hard pipe kit , GReady E01 with Emanage , FSE fuel pressure reg and fuel pump , Gready turbo elbow down pipe cat pipe and 2" N/A nismo exhaust , Apexi oil cooler , HKS and Green induction kit with cold air feed , engine circle earth with voltage stabeliser , uprated blow off valve with about 4 hours on the dyno and in the process of fitting 25 shot of nos and intercooler sprayer which should give about 40bhp on top of the 310

    • Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi 
    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off. 
    • I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell.
