RB25 N/A TO TURBO CONVERSION 

Its meant to go back round to somewhere on the intake manifold but you do not need to run coolant lines to the turbo at all

@@cameronjansz88 coolant feed from the top bolt right. I think he pointed to the bottom onr. Btw why there's a bolt on the bottom below the coolant feed bolt

Turbo manifold, turbo oil feed, turbo oil drain fitting, turbo dump pipe and turbo. You can just take all the stock stuff from an rb25det and bolt them straight on. Then you will need other stuff like bigger injectors and intercooler and a tuneable ecu if you want to make real power.

90s Nissan is this emgine still working after putting a turbo on it and if so how much boost do you put on it

@@indirapeppe8167 Yeah as long as you get it tuned and have the proper supporting mods (intercooler, bigger injectors, bigger fuel pump) and always use at least 98 octane fuel its fine

@@90sNissan what power did it make?

@@R32_Sam 280kw on e85 i dont trust my tuner at all though couldve gone for 300 but i didnt want to keep going

Yes you are correct, you dont need to swap anything else, I only swapped the cam covers because I wanted to keep my old ones. Just make sure you get it TUNED

@@90sNissan that's great. thanks alot for the reply.

Did not run coolant lines to the turbo. Most turbos do not need coolant feed. Just make sure you let the car idle for 30 seconds before shutting it off to prevent oil coking in the turbo.

You can (best to run ) coolant feed from next to throttle body ( small pipe trace it down to radiator feed) return other side heater core( if you got S1 or S2 got these pluged like he showed you). You don't need to run coolant but factor comes with coolant because Japanese don't but unnecessary pipes for nothing 😅😅😅😅😅

@@sparklingsams3155 thanks for the advice. I decided to swap the entire engine for a Neo DET in the end.

Le Loup Rouge these motors are high compression so I *idk about him* used 5psi to make my engine last, i think anything above 7psi fucks it uo

You can run as much boost as a turbo engine can, but you have to get it tuned. Without a tune it will blow up almost instantly. Im running 18 psi with no issues.

@@90sNissan also depends on what ecu is thrown in. A apexi compared to a adaptronic will run about 10deg more timing across the map off the bat. But ofcourse a tune is the best bet.

@@90sNissan how's the 18psi going and any hp numbers?

It was 280kw on 17psi with e85 and 15psi on 98 petrol. Still no issues

No compression is higher which is why I run e85 to prevent detonation. 15 psi low boost 18psi high boost only for e85 Walbro 450lph 980cc injectors Rb20 and rb25 exact same exh manifold and turbo

Okay thanks. Crazy running 10:1. 😅 here in germany running e85 on the street is problematic. Maybe thicker gasket or better piston and rods.

8psi will last forever if you get it tuned

it will probably be a stock 25det ecu

It is a nistuned rb20 ecu running a rb25det map

Nistune

How did that go ?

@@meatsauce8454 still to complete,

And also did you use an aftermarket down pipe off the turbo and does it bolt up to stock rb25de exhaust

Yes had all cooler pipes connected. I had a full turbo back custom exhaust. If you dont have one i reccomend you just get the whole exhaust out of a r33 or r32

Okay so the down pipe off turbo probably would bolt up to stock na exhaust

@@SwdKlla it might but i dont know

Series 1

R33 gts series 1

No water feed for turbo, not needed

Still going strong mate. Been about 3 years i even turned the boost up to 20psi and its fine. Check my latest video

I used an rb20 ecu with a nistune chip

Can u use a rb25de ecu???!!

@@roseramsey7117 any r32 ecu. Rb20de rb20det or rb25de non vct ecu can be nistuned. I dont think the r33 rb25de ecu is tuneable though

Loops back around to the intake manifold. Didnt use one on mine, most turbos dont need coolant

@@cameronjansz88 thanks

Back of the motor, next to heater core return.

Yes rb25de series 1 from an r33 gts

@@90sNissan what did you use or did for a tune since it’s high compression?

@@robbienguyen4307 I used e85 for high boost and 98 for low boost

@@90sNissan thank you for the reply, appreciate your time! How about your ecu? Man, I’m in the eastcoast we have 93 and e85 certain areas Any recommendation for ecu ?

@@robbienguyen4307 i used nistune but i would definitely reccommend something better like haltech or something

It loops back around engine to intake manifold. I didnt run coolant to the turbo

@@90sNissan sweet , your engine still going?

Probably, this entire thing took q couple days and less than $1000, a mechanic would charge alot more than that

Do it your self. Easy.

U can but its not ideal

@@deadlychoppa7791ceith a 10A instead of the stock one at vct drain. So it got got more room to drain.

Have seen it done. Just heard not ideal with the amount of oil flowing thru your turbo. I was going to do it but ended up getting a sump that already had a fitting for drain welded to it

Im in melbourne
