[HELP] RB25DE -> RB25DET

[Alf]

and i'm no guru but working a NA compared to a turbo surely would be more expensive for the same power gains

Your not getting it, more power = more dollars.

and u thought u were trying to do things cheap. :bs!:

[gatty]

cheap as in <3k

what i am trying to say is you spend 1000 doillars for example on a NA and get X kw gains

you spend the same 1000 on a turbo motor and get yourself 3 times as much gain for your buck

Get a 89 dolalr boost controller and ind it up a few PSI etc - thats NOT EXPENSIVE

[Greg]

good luck with the conversion mate, are you planning on doing the work yourself? i like the idea of bolting a turbo up to the RB25DE and running low boost. will still have good power off boost and be cheaper in the first place. only issue would be tuning ie what computer to use. I doubt the stock GTST ecu would work?

[Greg]

what do people think of an SR20 in a R33? megalla did it in his r32, and I think it makes sense. less weight, better handling. and unique. i can see myself doing that one day just for the fun of it

[666DAN]

Do it, do it. Gatty I'm sure you'll find the tuning process a billion times better than I did, the R33 ECU just doesn't have all of the bullshit self-diagnosis the R34 has. For god sake the R34 ECU will show a fault for the stupidest reasons....it's pathetic!

After messing around with ECUs for the past year I'd say throwing the turbo ECU in and backing the timing a few degrees should be fine...looking at the diagrams for it, you should have absolutely no error codes on the thing.

Keep posting to this forum.. this is interesting.. As ive had a few friends look into converting from N/A to turbo.. one sold his car after 6 month of frustration and got a GTS-T, lost about $4000 the other mate is still looking into it..

[666DAN]

Yeah frustration is a pain, I've had a year of it But that's what happens when someone overseas left out loads of what they did to the car they turbocharged!!! Grrr

When the exhaust is done on my one, that's it finished

Here are a couple of pics of what a turbo N/A look like...when I get the custom pipes done, it'll be almost impossible to tell it was N/A...only the *trained eye* will spot the variable intake, and lack of the word turbo on the engine cover

[gatty]

wow - some action int he thread now

dan your just the man i wanted to see this thread

i will be doing the work myself - yet thats going to be a BIG challenge for me...

ECU wise probably a wolf maybe? or even another piggy back system or maybe a stock GTS-T ECU - haven't decided yet, but i'd say I will use a standard GTS-T ecu

when i get all the bits i hope to get it done in a very short time frame

i'm liking the idea of bolt on turbo now and rb30 bottom later on...

[666DAN]

I'd say the bolt on job would be a lot simpler for you, I'll try and get some more pics of where all the fluid lines are connected to give you a better idea of what's needed.

[gatty]

if you could mate that'd be sweet

[sigsputnik]

you better keep us up to date gatty. k?

[gatty]

i will be mate - i am still planning the thing - but i want to gather all the info I will need first - so i have a good idea about what exactly has to be done

[666DAN]

OK some more pictures, probably helps if you stare at the engine bay to get a feel for where they are.

The first one is the oil feed, to see where this is you'll need a torch to scope around under the intake manifold.

This one is looking down to where the AFM hose connects to the turbo, where the engine mount sits. The oil return was passed through the engine mount, to the turbo. The return end goes to a 90 degree tap that goes through into the sump.

In this picture you can see the braided oil feed hose, that goes around the back of the engine to the other side as shown in the first picture.

The water return goes to a 90 degree tap that goes into the block. The feed comes from the heater hose near the fire wall.

Hope you can make some sense of these pictures

buy a rb25det block and put it on your NA head, then buy a turbo exhaust manifold and the turbo.intercooler you will need and u can use your non turbo ecu and get it remapped. by using a det block you will be able to run normal gtst boost with out blowing your motor, the gtst block also has the oil squirters, stronger pistons and lower compression.

[gatty]

thanks dan

[gatty]

dan - you need to make holes etc in your block etc etc for water/oil lines? or are they present but plugged?

[666DAN]

Yeah, they had to get tapped

[gatty]

damn, i assumed so - you get that done professionaly? you would have had to remove motor during the process?

helping a mate remove his blown turbo on his 33 the other day if the holes where there i reckon it'd be a fairly simple process and wouldn't even need to remove the motor...

[666DAN]

Yeah had it done professionally, but they managed to leave the engine in the car, so it didn't cost as much as it was going too...don't ask me how they managed to do it though, it was in some very tight spaces!!! I was actually amazed!

[gatty]

wonder how they managed to get no shavings in the sump etc

if you don't mind me asking how much was it - how long it take em?
