mamba_888 Posted October 18, 2006 Share Posted October 18, 2006 Hello... First and foremost, I've done a search on this subject but could not find anything close (maybe my searching skills sux but that's another issue). I found R.E. Hanvey's link called the Datsun workshop and he has this phenomenal 240z with a carburated turbo setup! http://www.geocities.com/row4navy/rb26swap/datsun7.jpg In looking at the pix (links below), I can't really tell if he mounted the carb onto the air intake of the turbo compressor! http://www.geocities.com/row4navy/rb26swap/turbo1.jpg http://www.geocities.com/row4navy/rb26swap/turbocarb.jpg Is this true? Can one do this and use the compressor to ingest an air fuel mixture directly instead of just air? Am I seeing the setup correctly? I can't tell by the pictures so I ask you gurus to please educate me! Thanx. Quote Link to comment Share on other sites More sharing options...
mtcookson Posted October 18, 2006 Share Posted October 18, 2006 That'd be the easiest way of setting it up. The only downside is you can't run an aftercooler easily, if at all. Boost will be limited due to heat but I'm sure it'd still be pretty fun. There are carbs out there that are designed to handle boost though. You could run a traditional turbo setup with an aftercooler. That would allow the most performance. Quote Link to comment Share on other sites More sharing options...
mamba_888 Posted October 18, 2006 Author Share Posted October 18, 2006 So I am seeing it correctly then. Thanx for the update. I did notice too that the IC is not in play here but apparently, he is still getting over 500hp on this setup! Hmm.... what to do, what to do... (with my current 240z project)!

rztmartini Posted October 18, 2006 Share Posted October 18, 2006 that looks like the turbo tom setup that one member has (or had) for sale on the classifieds on this site...for the $ he wanted for it , it would be a killer deal. too bad he isnt able to ship it...

alexideways Posted October 18, 2006 Share Posted October 18, 2006 I saw a guy once with a similar setup and what he did to cool the air/fuel charge was to use a water tank pressurised by boost and an boost actuated valve. When the boost would reach a preset point, the valve opens and send a spray of water via an injector in the intake. Quote Link to comment Share on other sites More sharing options...
Sparks280zt Posted October 18, 2006 Share Posted October 18, 2006 That car was bought by Bob_H or is it Bob H? Either way, he pulled that set up and its for sale. Quote Link to comment Share on other sites More sharing options...
Tony D Posted October 19, 2006 Share Posted October 19, 2006 That'd be the easiest way of setting it up. The only downside is you can't run an aftercooler easily, if at all. Boost will be limited due to heat but I'm sure it'd still be pretty fun. There are carbs out there that are designed to handle boost though. You could run a traditional turbo setup with an aftercooler. That would allow the most performance. That is a Turbo Tom's system, and is typical of old-school draw-through technology. For what they are, they work well enough. But what exactly do you mean by "Boost Will Be Limited"? I ran 20psi on mine (Crown Setup, basically the same thing), and that setup will easily get a full bodied ZX into the low 11's! hardly "Limited". The fuel in the turbo acts like anti-detonant, and over 17psi most people simply injected water, or alcohol, allowing almost unlimited boost---limited more by the turbo configuration than the heat issue. Anti-Detonant injection is well documented in it's effectiveness, you just need to inject enough to change state to remove the heat of compression. It's not an intercooler, and many pooh-pooh it, but it works. As for most performance, these setups were in the 9's almost 30 years ago in Z-Cars in Japan. Those cars ruled. The EFI revolution is what made current aftercooling effective for the masses... Quote Link to comment Share on other sites More sharing options...
GeeZ Posted October 19, 2006 Share Posted October 19, 2006 It is a Turbo Tom (R.I.P.) setup. I have such with the water injection setup. I worked well. Glad to see another. I blew the turbo and replaced it with a Turbonetics with a water jacket. I is laid up with a leaking head gasket. Tom was way ahead of almost everyone else. Sorry to see him go.
