Guest mrcow Posted March 25, 2005 Share Posted March 25, 2005 lets see if i can come up with a plan and yall agree or disagree with it... we take a stock 77 280z. add better fuel pump add 60mm TB add intercooler these are all things i would add with a 280zxt engine anyways buy a turbo exhuast manifold then buy a T03 and run stock 5-6 psi and that shouldnt be a problem, right? what do you think the max psi would be? would the above setup run alright with the stock ECC? i guess really i could buy a 280zxt ECC and later if i did a 280zxt swap and i come across another ECC i should be able to resell it without a problem. what other things could give me issues? injectors and dizzy? the 280zxt created how much HP with stock boost?

GrayZee Posted March 25, 2005 Share Posted March 25, 2005 would the above setup run alright with the stock ECC? i guess really i could buy a 280zxt ECC and later if i did a 280zxt swap and i come across another ECC i should be able to resell it without a problem. what other things could give me issues? injectors and dizzy? the 280zxt created how much HP with stock boost? I guess if you can find a place to get all the 280zxt parts.. ECU, AFM, injectors, dizzy.. ect then fine, but I'm thinking that they would be harder to come by than a 300zx. A 300zx ecu, maf, injectors, and even dizzy would be alot easier to find. I'm working on a adapter to run a 300zx dizzy on a L engine. Not only would it be easier to find, it's a much better system!

PUSHER Posted March 25, 2005 Share Posted March 25, 2005 300zx na or turbo? seems 280zxt and 300zxt are equally hard to find. Quote Link to comment Share on other sites More sharing options...
proxlamus© Posted March 25, 2005 Share Posted March 25, 2005 I am in the process of building up a turbo for an non turbo engine right now.. It has taken me a few months of building and preparing everything.. and carefully finding cheap and reliable parts.. and dozens of hours online researching.. so far with my 1978 280Z with the N/A N47 head and block.. I have gathered *Turbo Exhuast Manifold *T3 water-cooled turbo from a Z31 300ZX turbo *Oil Lines from a 280ZXT which bolt right onto a 280Z or 240Z using brake line brackets *Oil Tee to tee off the oil route from the oil pressure senderr *Toyota Supra Turbo 440cc fuel inectors *P.allnet 11mm o-ring fuel rail (coming in next week whoohoo!) *DSM BOV *NPR large Front Mount Intercooler *Turbo AFM *60mm TB with pig-tail potentiometer wires from a 240SX *60mm TB spacer kit from P.allnet (also coming in next week whoohoo!) *2.5" Mild Steel intercooler piping (2 u-bends, 1 90 bend, 1ft straight pipe) *Silicone couplers and connectors ( (1) 2.5"-2" reducer, (5) 2.5" couplers ) *Intake/Exhuast manifold gasket *Turbo oil inlet/outlet gaskets *Turbo manifold to turbo gasket *Turbo fittings for the watercooled center section and lines *Apexi S-AFC for piggy back fuel control *Oil pan.. I will use the N/A and punch a hole, thread a bung, and seal it properly *N/A electronics and N/A AFM electronics on that Turbo AFM *Boost gauge and lines I think that's it.. LoL.. I am very very close just need some time now.. For the oil pan situation.. you can use a N/A pan with N/A sump and N/A oil pump and you will be fine... you can't however use an turbo pan with an N/A sump.. so you need an turbo pan and turbo sump.. but the oil pan removal requires jacking up the engine and unbolting the engine mounts.. transmission rear crossmember, fan and fan shroud, a new gasket, lots of cleaning.. etc... so it's much easier to simply and PROPERLY punch a hole in the pan, and thread a bung and properly seal it, and it will be fine.

Guest 260ondubs Posted March 26, 2005 Share Posted March 26, 2005 What I think a lot of people missed was this: "I live in Australia and we didn't get any L28ET's" I had to import a probably dodgy US one, or build one myself with quality parts. My build is no cheapskate build so after reading all the information from some contributors I am happy that my engine will survive. I think it helps that even the stock N/A CR is pretty low to begin with. Quote Link to comment Share on other sites More sharing options...
GrayZee Posted March 26, 2005 Share Posted March 26, 2005 300zx na or turbo? seems 280zxt and 300zxt are equally hard to find. All the electrical components from a 300zx and 300zxt are the same other than the programming of the ECU itself, and if the ECU is 87-89 then it can be re-programmed. The injectors are the same too. The o2 sensors are different, but that's minor detail. Quote Link to comment Share on other sites More sharing options...
