My Zeds now in the garage for a serious make over. Got myself a Eaton supercharger and a Tremec T56 6 speed gearbox . No idea how to connect the lot up but thats part of the fun. My zed is a NA. Can anyone tell me if the block and crankshaft is the same in both the NA & TT, or is the TT block and crankshaft stronger? [
Impressive, i like :zlove: to my knowledge (and i could, and most likely am wrong) but the block for all z32s is the same, to be honest im not sure abuot the crankshaft though, my gut feeling would be that they are different, but not sure. very intersting project though, keep us posted on the progress when you begin
I drive an NA too. I've always heard about supercharged zeds and most have said that you have to get rid of the aircon or something. This will be an interesting project to follow. I've read abit into NA into TT conversions and don't recall hearing that the Block and Crank are different but I may have missed that. Do you plan on having the standard NA internals? Or will you go for a lower compression ratio setup to allow more boost? Good Luck! Sandeep
track car of street car? if its a street car, good luck with getting it over the pits with a top mount blower... the bonnet hump will have to be so high it will cut out alot of vision, hell even on a track car you'll lose half your line of sight to your left. I've done abit of looking into the subject, remember the NA engine can only go up to 8psi intercooled or something i read somewhere, so it can't handle THAT much from a big blower, my plan was to get a smaller blower and mount it where the a/c was. if its smaller ill run the boost a little higher but still not over the 7psi intercooled level
Heat? The beauty of superchargers is that you don't get the heat problems associated with turbo's and you don't get turbo lag either so it's all good. Problem is where to mount the damm thing(s) - they have to be belt driven.
Problem is you dont get nowhere near as much power as you do from a turbo, turbo owns the supercharger in top end also. So its a cheaper and more powerfull solution for a Z. Where are you ment to mount the SC in a Z? And you can only boost it too 8psi, so whats the point of that?
Daily driven = better bottom end grunt Why dont you go the whole hog and convert it into an LS1/6sp/SC
na my zed will be NA for a while.... got me a new job thats doubled my pay so i might start playing with the idea for a track car
lol GL fittin that SC... u would be better off with getting a thermo fan and putting a small one on.... one of the ones that bolts onto the pulley and isnt belt driven.. as for those talking up superchargers, superchargers WERE the in thing. i remember reading somewhere they drain up to 25% of the natural engine potential (sc dont lose power due to forced induction of course). and like i said they were the in thing, then a little buddy came out you guys might know as the Disco Potato (gt28rs) and put a end to the supercharger reign. to fit that sc buddy i think ull be lookin and some serious relocation.
Yeah, mega PITA! I was considering this a while ago. The best way of doing it is to use a SC14 off a Toyota 1GGZE and put it where the air-con compressor is. With the Eatons you need to have the intake on the back, while still having enough room to have a roughly equal length intake manifold. There's not too many issues with sticking it out the bonnet as long as you use a scoop made from ally with sufficient reo to stop a passenger being cleaned up by it... Remember that superchargers discharge is REALLY hot when the boost is wound up a bit, you really need some sort of intercooler/water or methanol injection if you want to run anymore that 9 PSI Turbo's are the new supercharger's. They are better in all cases except for lag. Bottom end grunt on a NA is a bit pointless, top end is where it's at! Just for random supercharger info: Toyota used to make a little supercharged corolla in Jap-land, pretty cool bit of kit, but HKS thought it was a bit lame... So, why not stick on a turbo as well?!? Well they did... Twincarged 'rolla, supercharger until 4000rpm, then turbo all the way to 7800 If you could pull that off on your NA I'd be impressed
well if he could fit a supercharger up there... and the anatomy of the engine is the same through and through... he could fit 2 turbos down under too right.... new fad eh, supercharging TT zeds would give a awsome torque range with bigger turbs, no turbo till 4200, no problem :zlove: the intake on a TT/sc combo would be hella messy or really smart.
Here's a piccy, not very good though... This a 20 valve (5 valves per cylinder) with a SC12 and a Garret T-03 read up here Note hi-tech things like quad throttles, map sensors and pits of plumbing pipe from the hardware store
No, that was the only factory twin-charged car ever released though. This was a turbo kit for the Corolla Levin GTZ with a 4AGZE 1.6L supercharged DOHC. The kit came with: Turbo manifold Turbo not sure what type Pipeing Injectors ANOTHER intercooler
Good points made above, Superchargers are not even close compared to Turbochargers as far as the efficiency factor goes simply due to the fact that they are belt driven and they're real pricks to intercool aswell. They are hard to install, big fitment issues and you almost certainly wont be able to close the hood and will need a cutout and you probably wont gain much more than 50hp or so... They're a waste of time in my opinion on Z cars, I've seen it done to a Z31 and it looks plain ridiculous.
Like this one, http://www.300zxt.com/videos/supercharged-z31.wmv Still a huge amount of money spent for little power gain, still not worth it although very cool for the "wow factor" if anything.
response. wide tracks aside, around tighter tracks with more turns, a tuned NA or SC setup will be the quicker one.
