Not a pro on the TT set up, maybe the TT guys can help me sort out the way nissan put her together. Some of this is from my last posts, but when I split the posts up seperately, ppl dodged all but one completely. I need advice!
I got an oil cooler with my TT oil tree. I was wondering when Twin turbo oil tree gives oil to the cooler, does the cooler outlet empty back into the oil pan? I noticed a little inlet on the pan besides the main oil retuns for the turbos, is that where the cooled oil goes after it goes through the cooler? most sandwich plates route back to the tree, but I see no such way with the TT tree. Whats the route of oil there?
Also could I route my turbo oil supplies off the tree? I know I COULD, but would it work well enough? I see everyone doing it for turbo upgrades, is there a better way? On that note also Can the oil supply be from the tree->turbo-> and return to the pan without a huge pressure change? (usually when ppl add turbos to a previously non turbo engine everything routes back to the oil tree for some reason I have seen with sandwich plates and such, I assumed it was to keep pressure or lack of a modified oil pan to fit return needs, whats the verdict on that?)
I realise the TT and N/A pumps have a 30psi difference from what I hear, I know it can be done with an N/A oil pump, I have seen it, but is it going to give the basic needs to my engine for now? changing later is on the list of course
How large of injectors could the N/A fuel pump handle? I have the 370cc TT injectors, but will the N/A pump handle it well or will it need a booster pump? What is the max cc injector the stock N/A pump can handle?
I will be adjusting air/fuel ratio with with apexi afc.
PS. I don't need the N/A vs TT speech, I know its limited in many ways, its just a free time conversion project. Just let me know about the above, part or all if you can, thanks in advance
Questions about TT Specs
Re: (evildky)
I appreciate the help evildky, but I think you are describing a similar revolution of oil like a sandwich style flow would have given me, could be wrong though so forgive me. A sandwich plate would send oil through the cooler, and back to the plate to then circulate through the engine. A lot of stock set ups for turbos originate this way nowadays OEM to my knowledge.
I was just informed by some rather good Z parts people Oil flow is Tree-->cooler--> to the oil pan through the inlet I mentioned above, so that is resolved. I always found that unique about the Z, the changes they make to satisfy the uniqueness of the Z.
I was also informed that using the TT oil tree to provide oil to turbos is perfectly acceptable means of supply. Pressure will be ok
I also came across that an N/A fuel pump can handle up to 400hp in fuel pressure, from concept Z. So TT spec injectors and up to 370cc will be ok, the old one cc per one hp rule should limit me to the 370hp max possible hp and have safe fuel containment. If I wish to upgrade further, I will need a formidable booster and injector combo.
Short post, got my answers elsewhere, thanks anyway people
We'll see how it all goes down when I put in the new injectors on and wire the cooler.
