Guys,

i did a search and none of these came up..i guess...heh

In my never ending quest for more GO, ive got some questions abt turbocharging...

1) in regards to the RB25DE and RB25DET, what are the differences? Am told that the difference with the RB25DE is that the cams have higher lift. What is this? And that the pistons are different. Thats it. If u change the pistons, then it basically is fine then cause the Compression will go down if u change to turbo pistons or is there more than that i shd be aware of?

2) What else in the car differs? besides brakes and gearbox?

3) what kinda power is the Non-turbo gearbox good for?

4) presumably, i slap in a r33 GTS-t ecu, std turbo and manifold. And then an o2 sensor(dont know why but someone told me i shd) and a GTS-t AFM(or are they already the same in the non turbo) i shd be able to run maybe 0.3 bar? with my present 10.1 compression ratio?

5) presumably i buy the GTS-t ecu ahead of all the parts above and put it in, will my car still be able to run with the GTS-t maps?

thanks...and nheh...my knowledge base is limited and based on mainly what i hear around...nth expert wise so...if ne of the above are wrong, i would be more than happy if u wud correct me...thats why i posted...

hehehehe

thanks in advance guys

better off getting a gts-t. furthermore the price difference is not much.

if you buy a gts, you'd be kicking yourself for not buying a gtst. the mods you have to put on to be on par with a gtst is more than the difference you pay for a gtst. trust me, the gtst would make you smile for quite long in standard form.

The DET engine has oil squirters in the piston bores, which I think the DE doesn't have. If so, you will probably find yourself with a variety of piston overheating problems, which you won't even know about until something ****s up bigtime. ie, it's not just that your coolant temperature gauge will read higher than if you didn't have the squirters.

If you really want to do this, the best way (seriously) is to buy a GTS-t front-cut, transplant the whole front end including gearbox and brakes into your car, then sell all the leftover bits to recoup a few hundred bucks.

A front cut can be had for around $2k I believe, which I think is a bargain compared to buying all the necessary bits separately and then shoehorning them in. The process of swapping everything over should also be a lot simpler than modifying your existing engine.

read the above :( It can be done, and the engine swap is fairly straight forward and the best option if you are so attached to your GTS and really MUST do it. A guy i know has done it to his GTS, seems to have worked ok.

Don't forget the big difficulty of registering, insuring the car and the like if its not fully engineered. Its fine to do yourself, but when you go to sell it you will probably have trouble convincing somebody to buy it. Or in a serious accident you may well be royally *f'ed* when the car is inspected.

will also still only have the smaller brakes of the GTS however, and the diff may be slightly weaker(?).

For $3-4k difference between a reasonable GTS and factory GTS-T to be honest i'd just be selling and trying to pick up a stock GTS-T for around $16k

      I don't like "actual computers" for in car use. They take time to boot up, have OS annoyances, and so on. Arduinos etc are ready to go a few seconds after power on, don't mind being agressively powere cycled, because everything is non-volatile, don't mind being shaken and stirred.

      As Fred would tell us, it's all about interpreting the rules. It's not a water sprayer, it's a water mister... But everything else you've said, 100%! Even a raspberry Pi would be great, use HDMI out for a display, and add a raspberry Pi CANBus hat to read values out from the ECU.

      Being a race car, and being in the era of the Arduino, one would think it would take little effort to build a controller to do the spraying based on a real physical measurment. Waaaaay back in the dim dark AS days, JE "designed" (as in, he had help) a microcontroller based intercooler spray system. It watched the difference between a temp sensor stuck on the core and one in the free air in front of the cooler, and if the temperature difference exceeded a (settable) threshold, it would activate the sprays. Thus, it only ran water when there was an actual need for water. If you stop to think about the actual physical things that are going on in that stack of coolers, there's probably at least a couple of triggering conditions one could come up with, and one could probably even run one pump with more than one solenoid valve, to allow water to be placed where it is needed, or at all points at once (if it is needed at all points). We're in the age of science baby. But.... I suspect that intercooler water sprays are on the forbidden list in most circuit classes, no? So only good for Targa type stuff?

      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...
