25de+t head on 26det block

I got an r32 gts recently. its a bit of a Frankenstein project in that its running an RB25de+t head(08U) on a RB26det block(05U). A gtr ecu untuned Im assuming, & gtr injectors. When I first got it, it was running real rough & would only start aided with engine start. I couldnt find a resistor pack in the loom so I peeled it open & found that someone has wired 10w10ohm resistors inline on each injector. So I got an OEM gtr resistor pack & wired it into the loom now it starts like it should but its still running rough. It idles fine & slowly rides off in first ok but as soon as I give it a bit more gas it coughs & misses. Im just looking for some advice/input/interest in this thing to keep me motivated on getting it running right.

I'd suggest taking your car to a tuner.

Certainly sounds like a mess. I can't see anyone diagnosing something like this online without viewing the car.

25de+t head doesn't make sense to me, It'd be just a normal non turbo head correct?

I agree with jmknights92 - I would also invest in a wideband too, check what those AFRs are doing.

      Short shifter r34

      By PLYNX · Posted

      Don't do it if your gearbox box has already having syncro issues. The short hifter will put a greater load on them. If you must I remember Nismo did a shorter shifter, with the top part being physically shorter and the part that went into the gearbox was the same as stock. In saying that I've had a C's short shifter (I think) in mine for many years, which was given to me as the previous owner was not sympathetic to the gearbox. Thus forwarned I was careful and had to modify my normal changing style. You have to be super accurate with your clutch and shifts

      R32 Sedan - Grip and Drift (have my cake and eat it too build)

      Well, after a week of daily driving and having to crawl out between the wheel and the side intrusion bars. I got myself a quick release setup. I went with an NRG short hub and Quick Release with some cute heart cutouts on the pull tabs. Nice and matchy matchy with the rest of the interior accents I have going on.  The only downside is the total stack height even with the short adapter is longer than the old HKB boss kit. Luckily I had some adjustment left on the column so move the wheel away.

      stock shifter with new bushes, springs and cup will improve it. Gktech do all the bits. The opinion as the years have gone on is the redline is not great in old gearboxes.

      Hi all   what short shifter do you use on your skykine r34?   my synchronous does have a problem and i was getting huge delay and grinding sound between 2nd and 3rd, did put shockproof red heavy stuff and it is great now/ no issues   would in your view short shifter screw this up?   people seems to suggest/ use cube short shifter and there is standard and premium. Seen review of premium as much better and less play. Thoughts?

      R34 oil and timing belt change

      By GTSBoy · Posted

      Yeah, there's a bit of a density and friability difference between pebbles and any of those other things. Silicone will definitely float in oil and so will be mobile enough to move around. Although, again, if it is upstream of the filter it really shouldn't go any further. I would only ever worry about silicone when it is in places downstream of the filter. Upstream of the pickup is a whole 'nother matter. We've all seen what that does. I have seen the most abominable crap settled out in industrial gearboxes, trunnion lube systems and the like, without any sign that any of it has touched anything in the machine. Just chilling in the bottom, waiting for the inevitable operator error that causes the whole machine to need to be dismantled for repairs.
