I was wondering if i replaced the intake manifold of my RB25DE with a RB25DET manifold and got a turbo would my car run turbo???If so would the headers on my exaust work???or would i even be able 2 find headers for mine that can handle a turbo? plz help any info will do plz....

Thanx,

Mate there's a bit more to it than that.

I think it would be a cheaper option to replace the current motor with a det one. You should be able to get some money back if you trade yours in too.

Easy answer is sell your car and buy a turbo model. Much less trouble, effort and better results.

Otheriwse you will need to get :

turbo

exhaust manifold

new dump/front pipe setup

intake piping

intercooler piping and cooler itself

new ecu (to run th thing)

plus a handful of other things i cant remember off the top of my head.

You will be limted in the boost you run due to the high compression of the non turbo motor. Plus other things like brakes, clutch, etc will not be up the task of sufficiently handling the new power.

But that being said it can, and has been done check this thrad for details ------- http://www.skylinesaustralia.com/forums/Re...lin-t69998.html

i did on R32 RB25DE.

it's pretty easy and in my opinion it works out cheaper than getting either factory turbo or swap for DET motor (well, it did for me - check your local market rates).

i don't think 25DE s worth much money, except for the head, apparently ppl use em a lot for RB30DET conversion.

there is a problem of legality of doing it, check your local rules and regulations first.

No idea on R34 but, apparently R33 ecu can't be chipped, but I think you can use a chipped R32 ecu to suit your set up. Also, not sure other RB25DE has provisions for oil/water line on the block. Mine did but I also talked to someone else who did it, he didnt have them on the block (I think it was off Stagea)

if you can get the whole setup off someone upgrading to a bigger turbo, it makes your life a lot easier than trying to chase this and that all over the place (which I ended up doing).

here are my parts list (most are covered by stolen_s15)

• turbo (+ water and oil line + gaskets)
  
• exhaust manifold (+ gaskets)
  
• dump pipe
  
• front pipe
  
• J-pipe and blow off valve
  
• intercooler and pipings
  
• hoses and fittings for PCV & vacuum lines
  
• high flow fuel pump
  
• pod filter or turbo airbox (N/A one doesn't line up)
  
• some fasteners (unless they come with turbo etc, if you getting a whole kit, they should. I broke two manifold studs but easy to replace em. also needed to buy turbo to manifold nuts. I don't know if it makes difference but if you buy from nissan hella expensive and they needed to get them from japan. I ended up going to a stainless fastener place and got them cheap)
  

and it pays to check your ignition system - coils and plugs - boost exposes defects that don't show up in N/A motor.

DE+t shaved about 3 seconds off 0-100kph time and 50-70 and 100-120 times (which i think is more practical in everyday sense) are a lot better, so definitely worth it. And this is with 9psi and a generic tune. With dyno/road tune for your specific seup it should be better.

I'm going a little bit further now, with front mount intercooler, 440cc injectors and front facing plenum.

you might want to go front mount and injectors while at it, a little more work and expense but save on tune/chipping later when you do want more out of it.

Oh, you don't need to change intake manifold.
