While we are on quick questions lol

Im looking at getting an RB25DET engine package that used to be an auto, will this matter for me? (going into R32 as a manual) I know you change the flywheel etc but what about the ECU...

you can use an Auto ECU with a Manual but not the other way around. The only thing that will be a pain in the ass will be getting the auto sp.i.got boss out of the end of the crank but it can be done. you will probably need (well it'll be easier) a manual loom from the trans to the EB relay box but you can adapt the Auto one if you want to.

Quick question..i know you can buy a trans cooler for your auto..can this also be hooked up into a manual transmission?

As for the Trans cooler question, no you can't because there is no pump to move the G/Box oil. With an outo it is basically a big pump so there is a pressure feed to push the fluid through the cooler but with a manual they rely on contact transfer to move the oil through the box and there is no pump.

In race cars that need a cooler in their manual trans's they run an external pump to move the oil around. They also run a thermostat as the oil needs to be allowed to get up to temp.

Why are you thinking of fitting a cooler to a manual trans, they don't need it unless your doing long stints (1hr+) on the track?

Thanks DStrils, if I get that one I may aswell just get another loom because they are pretty cheap. The reason it caught my eye is auto and 81k say tight motor to me...

edit: Had an epic dumb moment, its late ok :D

the engine looms should be the same it's just the loom that runs down the drivers side of the engine that the alternator, oil pressure switch, transmission etc run of that's different.

Main reason would be just to keep the manual box nice and cool. Im not exactly awesome with a manual, due to lack of experience, and wouldnt mind having some kid of insurance so i know that the box wont be rushing hot oil and such. I was just thinking this because i remember seeing the trans coolers on the gtr z-tune, and whilst looking pretty scmick, makes sense to me.

    • You now say stumble, but you said cut out before. Will it slow rev through the cut/stumble? What gap were your spark plugs set to when you them in?
    • I had double clamped all the pipes but I checked them over any way, everything tight and secure. feels and sounds like a electrical short/failure, as it is an abrupt and aggressive stumble, that instantly comes and goes right at 4k mark...like clock work fuel pump and filter are new new coils and plugs injectors where cleaned and tested 200 miles plus ago no black smoke cleaned MAF   same results, other ideas? some other sensor?  
    • Yes, just without the annoying use of the word hybrid. We stopped using that term 20 years ago when we realised it meant different things to different people. Even "highflow" can represent more than one way of achieving the goal of getting more flow out of a turbo. But at least it says what it does on the box.
    • OH, when they say "solid buckets", I always interpeted that as "shimless". (Which is not the same as the "shimness word I invented above to represent the same idea that the buckets act as shims also!!). Still the same problem though. So it appears that buying a "kit" from Tomei is a two step process. Makes sense. Doesn't make sense in the context of a "kit" though.
