First of all, Hello. Im new to your fourm. I have been swaping sr20dets in to the US spec 240sx for 5 years and about a year ago I got 2 rb25de motors really cheap... so now i want to put one in an s14 I bought on Ebay but I think i will need to go turbo to make 350hp... (sorry I dont know kW) anyway do you think it can be done with out changing to lower comp. pistons? say I just bolt up a stock rb25det manifold and turbo... i have the r33 rb25 wiring harness and mafs ... i still need an ECU tho... and i used left over sr20 370cc injectors. I would kind of like to get it running with the det ecu, mafs, and inj. then add the turbo. so what do you think ? will it work or am out of luck? oh here are some pictures of my sr s14: http://www.entuning.com/jex.html

and pictures of the s14 that will be getting the rb25: http://www.entuning.com/black240.html and sence im introducing myself here I am at a show last year:Christopher Jex Dallas Texas

i think it would work. The question is of reliability of course. If you stick to using low boost levels, 5-7psi, then you could get away without lowering the compression. I hope you were talking about using a stock RB25T ecu, because i dont think the Non turbo ecu is up for the task.

ive heard u need more than that.

stuff like an o2 sensor and etc.

Go to the FOrced INduction performance section or do a search for my thread, "parts needed to turbocharge" and it might be of some help

:P

no piston coolers but is there any modifications we can make to it to make sure the pistons dont overheat etc?

my mechanic quoted me arnd 8k yesterday for a full job..

forged internals, conrods, gt30 turbo and etc etc...expects arnd 300 at the rw.. or with forged internals, i dont need the piston coolers?

Well im sure they (Nissan) didnt just do extra work and spend extra money out of the goodness of their hearts... there is a sound engineering reason for them. that said I think if one is cairfull you can run a turbo on anything and be safe just so long as you do it smart... ie: big intercooler, oil cooler, bigger radiator, maybe even water injection. I know the FWD sr20de's here in the states came with out the oil squirters and jim wolf tech. puts them in fairly regularly. I'm planning to run my rb25de-T whith out them, but I'm also planning to run low boost 5-8 psi. I think you wil be ok making 300hp with out them ... i think 350 will be ok. if i can ever find an ECU I will report back annd tell form experiance what works and what does not. Cjex

      Ceramic turbine damage to engine - what did yours do?

      By Erelyes · Posted

      Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.

      Here's the chart for fuel pressure vs. current draw, assuming your base fuel pressure is 3 bar and you run like 0.5bar boost on WOT, you should only momentarily hit 9amps here and there. (Ignore my prev post, I cannot read a chart these days it seems)

      Those comp test results are not hideous. Whether they are accurate or not (ie, when that comp tester says 140 psi, is the real pressure120, 140 or 160?) is unknown to us. The state of the battery used to crank it over is unknown, etc etc. Many people around here would say that the absolute values and the spread are perfectly fine to just add boost and keep going. I personally would be happier with a narrower spread than that, but even the diff between 125 and 145 is not terrible. That one cylinder at 125 though, has probably copped some damage relative to the others. You should inspect the valves seeing as you've got it open. Do you know how to measure installed ring gaps? That, and an inspection of the rings themselves, is how you will determine whether they need to be replaced. If you're not good to do these things, take the block and the pistons and rings to a shop that is, and ask them for the go/no-go on them. Do the bores need a hone at all? If so, you might well be justified in getting some different pistons in order to get away from the ring supply problem. Whether you're happy to spend a lot more money right now, on more gear, rather than less money, but an amount that looks stupid given that you will only get a handful of rings in exchange for that money, is for you to decide.

      Ok so i would love some advice here please, i purchased an R33 a few months back and its had a few mods done to the engine, its an RB25det running a Master ECU, 1200cc injectors, bigger turbo, oil cooler, oil filter relocation kit, Spool H-beam rods, acl/ross pistons. When i removed the motor from the vehicle (as its getting a respray) i thought i would compression test it and these are the following results. Cylinder 1-145psi, Cylinder 2-143psi, Cylinder 3-125psi, Cylinder 4-145psi, Cylinder 5-140psi, Cylinder 6-135psi this test was done with the motor on the ground and powering up the starter motor. I dropped the sump and found broken oil squirters on cylinder 3,5 and 6. I was told my rings are probably worn so i stripped the motor completely to get a new set of rings for it. The trouble is no one has these rings anywhere and they have to be custom made by Ross over in the states and will cost about $600+$200 delivery. My question is how can i tell if my rings are at fault and if they are still ok and is this price ok for a set of rings?
