    I have a quick question...

     

    As air compresses it generates heat.. hence why turbo cars *should* have an intercooler.

     

    Now as air expands.. it cools. technically.. as the exhuast gas exits the engine... wouldn't it be more efficient to go from let's say a 2.25" to a gradual 3" piping in a relatively small distance? The exhuast gases would "expand" as the piping got larger, resulting in cooling, which means a faster flow??

     

    I could be wrong.. but a crazy assumption?!

    Need some help with my T3 .. wastegate flapper on downpipe!?!

    You got your Z31 T3 turbo.. and downpipe to fit in your 240Z???

     

    Other than the wastegate modifications... did you do any other mods to the car??

     

    Please please PLEASE take some pics!! Somone told me the Z31 downpipe will NOT fit because it will hit the transmission!!

     

    ohh I need to see this to believe it!!

    I just don't want to be screwed when I take off my intake manifold and bolt on my turbo exhuast manifold and turbo.. and find out that it actually DOESN'T fit :(

     

    Are you running a spacer?

    Looking for some pics of a Porsche 944 intercooler.. bad fit??

    Hey guys.. I have been debating between the Izuzu NPR intercooler and the Porsche 944 intercooler...

     

    Now the 944 intercoolers go for much cheaper on eBay and have a very good flow rating and are Bar and Plate design...

     

    However, I don't know about the piping issue and the fittment.. since the 944's intercoolers are very thick.

     

    I found these pictures from BumbleZee/WannaBREZ and his 944 setup, but honestly I don't like the intercooler sticking out that much.

     

    Anyone have any pics of their 944 intercooler or piping?

     

    Thanks!

    Need some help with my T3 .. wastegate flapper on downpipe!?!

    in Turbo / Supercharger

    Well..

    I recently bought a Z31 water-cooled T3 turbo... and I noticed something different about the turbo from the 280ZX turbo.

     

    It is the same turbo, just the Z31 is water-cooled, HOWEVER,

     

    The 280ZX turbo has the wastegate flapper ON the turbo housing.

     

    The Z31 turbo has the wastegate flapper and housing ON the downpipe.

     

    That stumped me.... I don't know if I can fit the Z31 downpipe on my 280Z ... but I do need to figure something out. I can run an external wastegate, but I don't need one because I am not going to be running much HP or have the money to buy one.

     

    Can I use the stock Z31 downpipe? Should I cut it and modify it? What can I do about the wastegate?

     

    I dunno... I am stumped.. and clueless.. I need help!!

    Reference Pics - My new Z31 water cooled turbo !! =)

    Well i finally got my water-cooled Z31 turbo in the mail!! Yay!!

     

    Anyway.. I needed to re-clock the turbo, because the intake outlet of the turbo was pointing straight up, so I re-clocked it, and I have to find a good place to bolt the waste-gate actuator on.. so I got an L-Bracket for that.

     

     

    I realize I may have to get a new down-pipe since the 300ZX downpipe won't fit..... but here are the pics...

     

    I DO have a question though.. how the heck do I bolt up my coolant lines to that bolt?? It's a hollow bolt with holes as shown in the picture... what kind of fitting do I use?

     

    (I searched for hours and hours and never found any good reference pics of the oil inlet and outlet fittings.. and what was the water-cooled section???)

    BLUE maybe you can use it as a reference

    So here's some :

    Need help identifying this Z31 T3 turbo.. water cooled??

    in Turbo / Supercharger

    Hey guys.. I recently bought a T3 Garrett turbocharger from a later Z31 turbo...

     

    and after looking at the turbo.. I need some help figuring out which parts are the inlets? and which are the outlets??

     

    I THINK it is water-cooled... but I am not sure.. can you guys help me out?

     

    Is the OIL INLET correct?

    Is the OIL OUTLET correct?

    Is that center piece the water cooled inlet? or is it not watercooled?

     

    NOTE : This is not an exact picture of the Garrett T3 turbo from the Z31.. however.. is the closest picture I can find

    straight pipe experimentation!!!

    i have the twice pipes setup.. with no cat..

    and 2 glass-packs...

     

    I LOVE IT SOO MUCH!!

     

    I like the gurgle and popping of the exhuast.. makes me feel like I have a rally car.. hehe.. and the occasional POW when declerating hard..

     

    My bumper is burned .. i swear it spits flames when my exhuast is really really hot

    Toyota Supra Injectors - 440cc - Um.. any performance gain in an N/A???

    Hey guys...

     

    I am slowly building up my parts for a kick ass turbo conversion...

     

    my latest bunch of parts i just purchased was a set of low impedance 440cc injectors from a Toyota Supra Turbo..

     

    Now i still have a LONG way to go, and alot of parts to get untill my conversion is complete.. but untill then....

     

    if I hook up those 440cc injectors and a new fuel rail.. will I be looking at any performance gains? I have a stock N47 engine.. with just intake and exhuast...

     

    But i figured.. ehh.. why not give it a try... maybe I can use these now...

     

    If i am not looking at any performance gains with pluggin the injectors straight in.. how can I achieve some performance gains?

    Turbo Conversion .. '78 280Z.. N47 stock block and head....

    in Turbo / Supercharger

    I have been extremely interested in a turbo conversion for my 1978 280Z.

     

    I have been searching around for a few years now on this site...

    and I understand it's better to just swap in a 280ZXT engine into my car..

     

    but my engine is running VERY strong and has only 100,000 miles on it.

     

    I would trust my engine ALOT more than a junkyard one, and i figured would be cheaper.

     

    But I am gathering a list of stuff that I need:

     

    ( i just need help to see if I miss anything)

    Turbo Exhuast Manifold

    Turbocharger and Wastegate

    Oil Lines

    Vacuum thinngy (what is the vacuum thing I need? what is it called?)

    Turbo Injectors

    Intercooler

    Intercooler Piping

    Downpipe

    Turbo AFM

    60mm TB

     

    Now I understand I will have to tap into my stock oil pan, or get a turbo oil pan.

     

    I hope to use a Z31 ECU or just go for MegaSquirt or SDS.

     

    Do I need another oil pump to pump the oil to the turbo?

    Am I missing anything else?
