Some of you may have read my thread on "I'm looking at a 180sx tomorrow" well the owner of that car John Duggan, has a tuff 180sx making about 310rwkw (you may have read the write up in the new HPI mag), any who the write goes on to say, that with some turning and some more boost, he may have about 340rwkw. Any who, as this guy is a wanker, as he put his price up on his 180sx, dad now wants a car with more rwkw's than him:rolleyes: so what mods and how much would it cost to get this much from his rb25det?

Later

Josh.

do it all

hehe

well we have the zost, fmic and pod, but when we do the turbo upgrade will we get a plenum and do all the fuel stuff.

Nismo I love your dads attitude :-)

a rebuild is required.so you might be better to find another block to start work with. just a block fit full rb26 crank and rods and forged pistons. you will need a large turbo like a t78 or so cams plenium and head work your motor and turbo will need to handle around 1.6 1.8 bar of boost.

you will need to sit down with some one and plan for it. it is very do able . forget the rb30 combo they dont fit in silvias properly.

the easier way is to fit a big single turbo rb26.

budget for 15 -20 k

pm me if you want more info

cheers

u gotta get that power to the ground

youll need good suspension

perhaps a better gbox

diff

n stuff like that

340rwkw is alot of power

yeah, 340+rwkws is a lot of power to get to the ground, and in a silvia, it's going to be even harder. A better box (maybe some thing like those OS gears?) and some form of diff.

the 25 swap is fine let your old man drive the thing for a while.

then you can do the mods you can use an rb26 if you want. you just need to plan it a bit more with the rb25 thats all remember forced was a rb 25 so its very do able .

the box might need a gear set. get the rb25 running then start to plan. you can do alot of the upgrades and still make 260-280 on the stock bottom end. then you need todecided if you want to go that step further. cause thats the big one

cheers

Drop an rb26 in it with 2530's or 2540's it will have less lag.

One quick lap around the block, and he won't shut up about it :)

You're starting to sound like a broken record Kabab :lol:

Your dad would look cooler in a GTR than in a Silvia :) :)

I never said we have millions of dollars. yeah, sure GTR's look cooler, but dads just being different with the silvia.

    • perhaps i should have mentioned, I plugged the unit in before i handed over to the electronics repair shop to see what damaged had been caused and the unit worked (ac controls, rear demister etc) bar the lights behind the lcd. i would assume that the diode was only to control lighting and didnt harm anything else i got the unit back from the electronics repair shop and all is well (to a point). The lights are back on and ac controls are working. im still paranoid as i beleive the repairer just put in any zener diode he could find and admitted asking chatgpt if its compatible   i do however have another issue... sometimes when i turn the ignition on, the climate control unit now goes through a diagnostics procedure which normally occurs when you disconnect and reconnect but this may be due to the below   to top everything off, and feel free to shoot me as im just about to do it myself anyway, while i was checking the newly repaired board by plugging in the climate control unit bare without the housing, i believe i may have shorted it on the headunit surround. Climate control unit still works but now the keyless entry doesnt work along with the dome light not turning on when you open the door. to add to this tricky situation, when you start the car and remove the key ( i have a turbo timer so car remains on) the keyless entry works. the dome light also works when you switch to the on position. fuses were checked and all ok ive deduced that the short somehow has messed with the smart entry control module as that is what controls the keyless entry and dome light on door opening   you guys wouldnt happen to have any experience with that topic lmao... im only laughing as its all i can do right now my self diagnosed adhd always gets me in a situation as i have no patience and want to get everything done in shortest amount of time as possible often ignoring crucial steps such as disconnecting battery when stuffing around with electronics or even placing a simple rag over the metallic headunit surround when placing a live pcb board on top of it   FML
    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily.
