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

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

      Could you modify this duct so instead it pushes the extra air through the radiator too and not down and out? For temps, I know it's not the greatest idea, but as a bit of a last resort, you could use a very intermittent misting spray onto the front of the coolers/rad. You don't want to be soaking them such that water is dripping off, but a small most on/off so that the water evaporates. That point of it constantly evaporating, rather than being soaked in water, will pull a LOT of heat out of the cooler. I'm literally thinking just the little mist sprayers for a garden from Bunnings. Being in a low humidity climate it will help even more! The other trick if you want to be ghetto is some shade cloth hung in the opening, and keep it wet. Pretty much now it's acting like an evap cooler on a house, but cooling the air you need to use to cool the radiator...   On a topic to think about too though, when air enters through the bumper, is it all nicely ducted from the edges of that opening back at a nice angle, or is it like most cars, and the edge of the opening just stops, and suddenly it's wayyy wider behind that? If it does the later, get it shrouded out at nice angles. When that opening changes too rapidly, it can actually cause a high pressure zone between the front bar and radiator, and limit air flow into that area, which means less air for cooling, as it effectively stalls the air, AND adds to drag...

      It doesn't look like there's a lot of options out there these days, and what's out there is performance oriented aftermarket stuff (with the GTR markup) I wonder if there are other cars with similar springs, after all its just a matter of length, diameter and stiffness. Alternatively, I did see coil spacers. Probably not the best option, but could be serviceable too.
