I'd be keen to supercharge my skyline, but id do it properly with an aftermarket supercharger.

What i want to know is, bang for buck what puts out more power: n/a + Turbo or n/a + supercharger??? (on a minimal budget)

that is like asking how long is a piece of string. unless you can give turbo and supercharger sizes it is a pointless question,

if the engine was a rb25 and it was NA + stock turbo or NA + toyota supercharger then i would have to say that the turbo will shit all over it. the toyota supercharger is miles too small to effectively provide enough boost in the top end of a 2.5L. even on a 2L it would struggle. you have to remember that the superchargers are generally for toyota's 1.6L engines.

i know people who have put them on commodores before and while they do make a difference it does trail off a bit up top. the commodore motors are a bigger motor, but they don't rev as high as the rb motors so it sort of balances out a bit and brings them closer as far as the volume of air they use

I was meaning an aftermarket supercharger coz i know toyota ones are shit, but i don't have much to spend so id say about $2k is my budget. Also n/a plus T = shit power you only get like 180kw which is like a stock r33 gtst.

When did Stock r33 GTSt's make 180kw? Mate take a 180rwkw NA+t against a 180rwkw DET and the +t will leave it miles behind.

Gee... I must have only picked up 5KW with all the mods done on my R33 GTS-t then...

FMIC, full 3" TBE, lightweight flywheel, CAI setup... 185KW (That was a "roller coaster" setup though of a power curve... Once tuned 193RWKW...

DE+twill be more tractable power wise off boost too due to higher compresion.

meh, my 33 GTST made 178rwkw with nothing but a frount mount... It was running quite a lot of boost though...

added an ecu, full exhaust, pod filter and gained like 12 kws...

Now it's over 200 with all that shit, but the turbo is pushing out a bar of boost or more...

Every car is different.

don't waste your time with a supercharger, especially if you have a 'minimal budget'. Modifying performance cars has nothing to do with minimal budgets...

firstly, 180kw is a hell of a jump over a stock NA. it is roughly a 60kw jump. what do you think is the reason why a NA+t using stock turbo etc won't make more power than a DET? and what makes you think that just bolting a supercharger on will be better? the reasons why a NA+t will only make as much power as a DET will be the same reasons why you won't get much of a different result with a supercharger install with a budget of 2k. do a NA+t and spend about 5k on the job and it will make a lot more than 180kw, as would a supercharger upgrade at the same money

When did Stock r33 GTSt's make 180kw? Mate take a 180rwkw NA+t against a 180rwkw DET and the +t will leave it miles behind.

not entirely true. if you have both cars crawl along at about 1500rpm and then floor it the NA will pull away, but if both cars are at around 3000rpm or a bit higher when you floor it the NA will pull away a fraction (doubt it would even be half a car length) as the NA will spool up the turbo quicker then they will both accelerate about the same. at the end of the day 180kw is 180kw. the NA will have more down low but up top they will both go the same. the only other thing that may make a difference is the gear/diff ratios. which ever ones has the shortest ratios will have the quicker acceleration, but will have to change gears sooner.

lol.

dont compare the kw, compare the torque & response difference.

eg: i made 180 on 10psi but torque was around 499nM

comparing with other 180rwkw RB25DETs around they were getting 400~ nM of torque and were probably running bit more boost as well

Furthermore to dori's post... you can make alot more then just 180kw..... but you must have the MONEY/time/motivation/know how and tuner...

if this is the dude in newcastle im thinking about that reckons he's strapped a supercharger from a toyota on a n/a skyline it run's like a f**king piece of shit and the bloke is f**king full of shit, and yer apprently he put something like this thread up on "SAU" which im assuming this is it so yer

      Duncan's V37.......race car?

      By Duncan · Posted

      So I mentioned the apprentice, @LachyK helped take the bonnet off. We just undid the nuts on the hinges and unclipped the gas struts, then pulled the bonnet back a little as the front was catching on the front bar.  I had a good look at everything today and have removed the rams, repaired/reset the hinges and bolted it back together like it never happened. I'll do a separate write up on the repair, and I also removed the poppers from the Fuga today too to save grief down the road.....as said above it is at least $5k to repair retail. I'm also happier about my ability to prepare a race car, and less happy about Nis-nault's engineering (I can hear @GTSBoy sAfrican Americaning) because the top hose of the radiator didn't slip off.......it snapped clean off. By practice I put the hose clamp hard up against the flare on a neck to make it least likely to ever move (thanks @Neil!). I guess that puts a little more pressure on the end of the pipe as it is further away from the rad, but still, that is pretty shit. I've put it back on for now as there was a fair bit of neck still there, but obviously there is no lip on the neck any more so I don't think I'll track it again until I have a new rad. Speaking of which....more research required. It looks like Koyo makes a standard size radiator in ally which I'll grab in the meantime, but I really want something thicker so might have to go custom in the medium term (ouch) Coolant still needs a refill and I have the pressure tester on it over night, but other than a wash down of the engine bay it seems alright. And @MBS206 noted something noisy on the front of the engine and I think I agree....time for a new accessory belt and tensioners I think.

      our good friends at nismo make a diff for it, I have one (and a spare housing to put the centre in) on the way. https://www.nismo.co.jp/products/web_catalogue/lsd/mechanical_lsd_v37.html AMS also make a helical one, but I prefer mechanical for track use in 2wd (I do run a quaife in the front, but not rear of the R32)

      R33 persistent issues. P/steering and lag/misfire

      By GTSBoy · Posted

      What are we supposed to be seeing in the photo of the steering angle sensor? The outer housing doesn't turn, right? All the action is on the inside. The real test here is whether or not your car has had the steering put back together by a butcher. When the steering is centred (and we're not caring about the wheel too much here, we're talking about the front wheels, parallel, facing front) then you should have an absolutely even number of turns from centre to left lock and centre to right lock. If there is any difference at all then perhaps the thing has been put back together wrongly, either the steering wheel put on one spline (or more!) off, and the alignment bodged to straighteb the wheel, or the opposite where something silly was done underneath and the wheel put back on crooked to compensate. Nut there isn't actually much evidence that you have such a problem anyway. It is something you can easily measure and test for to find out though. My money is still on the HICAS CU not driving the PS solenoid with the proper PWM signal required to lighten the load at lower speed. If it were me, I would be putting either a multimeter or oscilloscope onto the solenoid terminals and taking it for a drive, looking for the voltage to change. The PWM signal is 0v, 12V, 0V, 12v with ...obviously...modulated pulse width. You should see that as an average voltage somewhere between 0V and 12V, and it should vary with speed. An handheld oscilloscope would be the better tool for this, because they are definitely good enough but there's no telling if any cheap shit multimeter that people have lying around are good enough. You can also directly interfere with the solenoid. If you wire up a little voltage divider with variable resistor on it, and hook the PS solenoid direct to 12V through that, you can manually adjust the voltage to the solenoid and you should be able to make it go ligheter and heavier. If you cannot, then the problem is either the solenoid itself dead, or your description of the steering being "tight" (which I have just been assuming you mean "heavy") could be that you have a mechanical problem in the steering and there is heaps of resistance to movement.

      By MissMintyR33 · Posted

      Little update  I have shimmed the solenoid on the rack today following Keep it Reets video on YouTube. However my steering is still tight. I have this showing on Nisscan, my steering angle sensor was the closest to 0 degrees (I could get it to 0 degrees by small little tweaks, but the angle was way off centre? I can't figure this out for the life of me. I get no faults through Nisscan.

      The BES920 is like the Toyota Camrys of coffee machines. E61 group head is cool, however the time requirements for home use makes it less desirable. The Toyota Camry coffee machine runs twin boilers and also PID temp control, some say it produces coffees as good as an E61 group head machine.
