the_host Posted November 13, 2005 Share Posted November 13, 2005 Ok guys i got a 93 Import GZ Auto ... just recently bought it and during the Full Service... noticed it has no oil cooler or factory fit dump valve. I thought these models came with them??...or has the guy who had it in Japan taken them off??? Link to comment Share on other sites More sharing options...
Guest gzaerojon Posted November 13, 2005 Share Posted November 13, 2005 I believe the standard oil cooler sits behind the rad, it only cools the transmision oil, I might be wrong so correct me if I am, the standard dump valve bridges between the front 2 turbo pipes nearest the air filter box, it doesn't look like a dump valve should but its a small black valve.

TrickTT Posted November 13, 2005 Share Posted November 13, 2005 Engine oil cooler is a liquid cooled jobbie on top of the oil filter. Tranny oil cooler is inside the bottom of the main radiator and the power steering cooler is a lenght of pipe in front of the air con condensor which should be visible through the front grill (unless you have a FMIC) Link to comment Share on other sites More sharing options...

Post photo of your engine bay and we'll be able to identify if you have one at all. Link to comment Share on other sites More sharing options...
the_host Posted November 13, 2005 Author Share Posted November 13, 2005 Will post a pic of the engine bay as there is no aftermarket bov... will be soon tho .... i thought the std (tranny) oil cooler would be visable through the passenger side front bumper vent (like the intercooler on the driver side) but i have nothing there??

On mine that's the engine oil cooler. AFAIK that was standard. Link to comment Share on other sites More sharing options...
the_host Posted March 16, 2006 Author Share Posted March 16, 2006 Had to bring this post back from the dead, ive attached a picture of my engine.... can anyone find the bov?? Link to comment Share on other sites More sharing options...
terribleturner Posted March 16, 2006 Share Posted March 16, 2006 Intresting. Where does this hose go to?? Whats at the end of it?? Link to comment Share on other sites More sharing options...
LeeT Posted March 16, 2006 Share Posted March 16, 2006 i agree with james, your BOV will be at the end of that vac pipe in the drivers side bumper duct Link to comment Share on other sites More sharing options...

Ark Posted March 17, 2006 Share Posted March 17, 2006 Looks to me like the re-circ plumbing is open to atmosphere. Link to comment Share on other sites More sharing options...
geoffvalenti Posted March 17, 2006 Share Posted March 17, 2006 Looks to me like the re-circ plumbing is open to atmosphere. It does look that way, but it must be capped, otherwise the car wouldn't run. Link to comment Share on other sites More sharing options...
Ark Posted March 17, 2006 Share Posted March 17, 2006 Yes it would - I ringed the re-circ on the inlet side - that means unfiltered air entering the turbos. There's no MAF sensor, so it must be J-spec, which means this is perfectly possible. The re-circ outlet _appears_ to be plumbed back into the airbox pipe. Still need to know the answer to James's question. Link to comment Share on other sites More sharing options...
the_host Posted March 17, 2006 Author Share Posted March 17, 2006 Intresting. Where does this hose go to?? Whats at the end of it?? Just checked the hose and its been capped off, ummmm so whats the benefit of doing that? Link to comment Share on other sites More sharing options...
terribleturner Posted March 17, 2006 Share Posted March 17, 2006 Can you take or have you got a picture of the complete engine. Maybe one from each side?? Link to comment Share on other sites More sharing options...

Ark Posted March 17, 2006 Share Posted March 17, 2006 Just checked the hose and its been capped off, ummmm so whats the benefit of doing that? Depends whose question you are answering there! If it was mine, then capping the pipe means no dirty air can get to the turbos, and you definitely don't have a stock recirculating BOV. If it was James's question, then you've got a capped off vacuum pipe...achieving sweet FA. I would have thought that pipe would run down to an atmospheric BOV mounted directly on a boost pipe. If it's capped and going nowhere, you may not have a BOV - not necessarily a bad thing, but it puts your turbos at risk of stalling under boost on the overrun - the excess boost pressure isn't going into the engine because you're off throttle, can't vent to atmos with no BOV, so it goes back past the turbos, stressing them badly. So, which pipe did you check on? Link to comment Share on other sites More sharing options...
the_host Posted March 20, 2006 Author Share Posted March 20, 2006 I'll have to check where that hose is going.... but i've posted a couple of extra pics if it helps:blink: oooh and the question i was answering was James's, i followed the pipe and it's just tucked up in the wing with a cap on the end of it. so i guess there's no bov??

terribleturner Posted March 20, 2006 Share Posted March 20, 2006 This is so odd. OK last ditch attempt. Where is THIS hose going to?? Im just trying to look for something that doesn't look the norm. Link to comment Share on other sites More sharing options...
Supra ST Myster Posted March 21, 2006 Share Posted March 21, 2006 whats all the cable ties about on the pipe? Link to comment Share on other sites More sharing options...
lambertpig Posted March 21, 2006 Share Posted March 21, 2006 sorry i cant answer your questions but i can give a bit of advice. when i serviced my supra pipes were found to be missing or blanked off similar to your car. refit everything to standard including airbox if poss and you will notice a huge improvement like i did. why do people do these things unless they are a proven mod?

JohnA Posted March 21, 2006 Share Posted March 21, 2006 I bet this car is losing performance from all these 'mods' and 'improvements'. Who wants to bet that all those cable-ties are meant to stop the intake pipe from 'balooning' under boost, so now it's got less lag and *even* more direct throttle response. Oh dear. But hey, it's modified, that's all that counts right? Link to comment Share on other sites More sharing options...
the_host Posted March 22, 2006 Author Share Posted March 22, 2006 Added some pictures of the pipe and where it goes, dont know if it will help? God knows why there are so many cable ties?? bought the car like that so:search: but any suggestions would be good. Link to comment Share on other sites More sharing options...
Soonto_HAS_soop Posted March 22, 2006 Share Posted March 22, 2006 That pipe must just be a boost gauge pipe? Link to comment Share on other sites More sharing options...
terribleturner Posted March 22, 2006 Share Posted March 22, 2006 That's really odd. So can you hear a dump valve out of intrest when you release the throttle?? Maybe take some video of the engine while revving it up. As others said i'd definatly think about getting one installed (stock/aftermarket) and maybe look into getting some hard pipes to replace the rubber cable tied one.
