Rb25 Powered Hr31 Passage Gt


Recommended Posts

the tune/dyno was done over east, i've had a few little issues to sort out before getting it retuned.

the timing did seem a bit adventurous as you mentioned, so i backed it off a bit pretty much after my first drive just so i knew it was safe up until i get my trusted tuner to give it a once over.

when it gets retuned, timing and fuel will be backed off, however i'd like to wind some more boost into it if possible.

that's not my tuner, that was done over east.. as i said before, i think the figure is a bit ambiguous, but it's definately making in the realms of ~350rwhp.

a bit bored with the black rims (had the exact same rims/colour on my 33 as well) so i chucked a red lip on them... i think it suits, and was only a 15 min job.

cheers simon

i'm getting it all tidied up and what not to get it rego'd/permitted for WA at the moment.

then after that i've got a few things to put on/remove before it goes in for a retune, hopefully i can gain a bit more midrange rather than a very peaky power graph..might make it a bit 'easier' to handle too, 1980 design suspension isn't exactly up for for a 400hp kick!

nice car mate well done. couple of little things i may have done differently but overall its a really nice tasteful car

i'm acutally working on a 31 at the moment, not quite as unique as your's, its only a aussie r31 Ti, but has copped new motor and manual conversion. removed moulds through the doors, dog legs and front gaurds & shaved locating holes, boot lock, arial and shaved rear garnish and a line or 2 out of the bars its going gun metal (new honda colour) i think its actually called phantom grey or something. series 1 bonnet, series 1 lights, pintara grill with series 3 front bar with around 18mm chopped out of the sides to fit all the series 1 stuff. also is getting some balck 17'"s (6 spoke).

anyways back on topic great car mate well done.

ALSO, in regards to the questions about the "big fat superlights"

They are ROTA RB's barnd is ROTA, RB is model.

Rota sort of copy famous designs, work replica's and that sort of thing

anyway made in china (nothing against stuff made in china) I think and they do have a repution for being "brittle" but i personally have never seen a set let go. (quite a few local drift cars run them)

they are not that exspensive at all

R35 GTR Fan = Dick head post of the year.

I dunno why but ive always had a soft spot for 31's

And i gotta say thats the best power curve ive ever seen outta a KKR480...I was turned off buying one due to the lack of power and response....but seeing your results is making me 2nd guess my choice to go high mount and ext gate

    • I would absolutely be starting with this idea over all other possibilities. It sounds f**ked.
    • Lighting in the shed looks real good! Not lying, have shed envy lol. Maybe one day I can fk off from Metro Sydney.
    • I would be cautious with those 2000/2200 CNG injectors, swap them out for a set of 1550 aka 1650 Bosch stainless ones before you take out a motor.
    • I tested them all a couple times, haven't tested it warm or wet though. The only seemingly really weird thing was the cylinders plug closest to the dash was pitch black nearly.  Doesn't smoke out of the exhaust or anything.    Also sorry everyone for the very late response. Got busy with work and all and didn't get around to fooling with the car for awhile.  But an update! I figured out the cause of the lean condition, my intercooler had at some point exploded or something. It's clearly separated in a spot with black oily buildup around the leak, and multiple leaks in various vacuum lines. I've replaced it and the vacuum lines, and gotten new clamps and there are 0 leaks now after doing a couple smoke tests.   The car now runs significantly better and the exhaust doesn't overheat anymore. I still have the main problem though where the engine feels like I'm lugging it around sub 3500rpm in any gear besides 1st, 2nd It's less noticeable but 3rd anything under 3.5k and I need to downshift or the engine is clearly struggling when trying to accelerate at all, 4th is the exact same, sub 3.5k engine won't accelerate and its hard to bring it back up to speed, 5th gear doesn't feel like the car is going to straight up fall apart now but it still can't pull 5th. It slowly loses speed and rpm and ANY gas I give I can feel the shakes from the engine and it slowly dying. If I ever so lightly give it gas it will slowly and nicely decel till around 2k rpm instead of lugging. But it cannot accelerate at all or maintain speed.   If I go from first gear at 5 or 6krpm and then shift to second it also feels like it's struggling to make power till above 3krpm if trying to accelerate but I can cruise around parking lots at around 1-2krpm just fine in 2nd. It's just when accelerating hard it and changing gear you really notice it die down.  But even if you shift at way lower rpms it does the same thing till somewhere above 3k.  As far as I'm aware it's got r32 gtr transmission gear ratios with gts4 diffs. The tire size is 205/55r16 91h Above 3500rpm the car pulls and runs and drives quite normally and the power from engine sounds and feels very smooth.  It's perfectly driveable at above 3.5krpm but I drive on the highway alot for work and it gets really bad gas mileage in 4th at 4.4krpm. Not that I'm looking for great gas mileage with such a car, just I'm sure being at around 3krpm would be significantly better for it.    Have appreciated all your guys help. I do understand the engine may just be f**ked from running with a boost leak though.    One final thing I'd like to add is I'm only shifting so high in the rpm range is because if I don't I will feel the engine lugging bad with 0 power in lower rpms, pretty much anytime off boost trying to accelerate it feels really bad.  Also when I say 3500 rpm I don't mean exactly. Just around there.
