Installing vq25det turbo setup on vq35de

I know I know I know, this topic has been covered before, but not in enough detail I reckon. 

I have a crazy idea, grabbing all the turbo bits off the vq25det engine and whacking them on my vq35de. 

Some have said the turbo would be too small, but does that mean it just wouldn't make huge power or would actually just get blown to bits? And would a high flow turbo work better then?

I'm not interested in huge power, just a nice little boost up from stock. 

Seems silly to spend 10k on a turbo kit, when vq25det setups are right there... 

Tell me I'm dreaming

The 25 turbo would be too small, I have turbos from my vq30dets and even those would be too small for a 35 and I would guess the 30 turbo is bigger than the 25.  You can get high flowed vq30det turbos though that are so called rated for 400hp on a 30.  Could still use the rest of the turbo exhaust piping.

Got a mate selling his HKS turbo kit with Stillen exhaust which should bolt up on a PM35. Nowhere near $10k.

 

VQ25det plenum has very small runner holes compared to the VQ35. Not even close to matching up.

An inline VH45de from a Fuga or something like the below would give you some grunt:

It's not just the turbo kit. I've done about 4 or 5 of the VQ35DE turbo conversions ranging from 240AWKW to 660RWKW. Your supporting mods will be just as expensive as a HKS turbo kit to do it properly. If you do it yourself you will save big $$$.

 

IMO the best bag for buck on the street if you want approx 200RWK on a VQ35DE is a firstly a very well sorted and flowing exhaust with H/F CAT's(use Z34 headers and cat's), a Z33 manual diff(3.538) for those of you with the PM35 only as the PNM is already 3.538, fuel pump and good catch can setup. With those mods you should be able to get 180-190RWKW with good plug and play ECU like a LINK.

If you want more for a street car a supercharger is your next best bet. The supporting mods to make it work well and get you reliability. power will be about 220 - 240RWK.

Once you go turbo its a major game changer as everything needs to be adapted especially if your in the PNM35.

P.S. I am only talking figures with 98 Octane fuel for the boosted setups as E85 is another setup and power change. IMO is you have $20K put an LSA in it and say goodbye

Latest plan: give wife the car and just buy a faster car. Problem solved. 

Good idea. I was going to suggest selling it and getting the best RS6 you could afford.

Oof $$$$. I'm looking at importing a jzx110, still not the best bang for buck, but hard to beat a nice 4 door 1jz!

Yep I had a nice Cressida 2.8  many years ago. I was just about to change my Skoda Superb 2.7 for an Audi Allroad 2.7TT when I got to the bit where it said to service the turbos first remove the engine so for now I have settled for a boring but reliable (almost beige) 2005 Camry V6

      BCNR33 Blower Motor Resistor - Testing

      By itsforandres · Posted

      hello! does anyone have a schematic that shows how to test the blower motor resistor for the vac system? i believe the part# is 27761-15U00. I think the resistor is toast, but would like to be able to test it somehow before i embark on the journey to find a new one. cheers! 27761-15U00

      I don't know the answer to this, but did you have a look at the parts diagrams on amayama.com and see what they list around it for your car? As an example this should be it on my car. That's how I would check for required clips and things like that. But, I take no responsibility for you ending up with a box full of random OEM hoses, washers and clips after going down that path a few times. This definitely has never happened to me

      Most driving should* be done on one side of single lane divided roads. In the RHD world, you drive on the left side of the dividing line and the road is probably cambered equally on both sides. So your side of the road slopes away to the left. The same is true for the LHD world, just everything swapped to the other side and opposite slope. With a perfectly neutral, straight ahead wheel alignment designed to drive straight on a perfectly flat surface (or at least one that is level on the left-right axis, even if it has some slope in the fore-aft axis) you will not be able to drive on a cambered road without the car wanting to drift down the camber. You will need to add steering input in the opposite direction all the time. This is annoying. The solution has always been to set the camber and/or the caster to produce a continuous turning force in the opposite direction of the camber. The car will drive straight on the kind of camber for which it was set up, presumably as described in the top paragraph. But.... when the car is set up this way, as soon as you get into a lane, usually on a multi-lane surface road or highway, where the camber is not as presumed during setup, the car will usually pull to one side. In the RHD world, if you are in the fast lane on a big divided road, you are probably on the opposite camber compared to what the car was set up for (ie, sloping down to the right) and the combination of the setup and that camber will make the car want to go right pretty hard. Even a perfectly flat lane will tend to want to go right. There's no getting around it. Civil engineers who know their stuff (which is not an assumption that can always be made) will attempt to keep the variation in camber across a multi-lane road as small as possible, and if they can will attempt to make the fast lane as close to flat, or even cambered in the same direction as all the other lanes. This takes a lot of planning for drainage, control of levels, ability to deal with the elevation changes that occur at road junctions, etc etc. So it's not trivial to get it right. When they do make it work, then the annoyance is reduced, along with tyre wear, fuel consumption, etc. In theory, the civil engineers are supposed to worry about those aspects of road design also. * This used to be true, but now with very large highway systems, even just multi-lane surface roads running everywhere, it is less true now than it was, but the old assumption is the basis for describing the phenomenon, so let's just run with it for the moment.

      I think the consensus was that's normal. Sloped road surfaces or something? I remember @silviaz went through this before. It might be one of those things you never notice until you pay attention to it.

      Im not entirely sure exactly what or where its leaking from, he started to pull the boots to swap to my new tie rods + ends and it just vomited fluid, so he closed em up up, swapped the rod ends to the old rods and let me know so I can figure a solution out, im guessing its all origional as as I passed 103k miles earlier this year im sure its just in need of a full overhual/rebuild anyways.    If i could just yank it off and be good it wouldn't be an issue to ship it out and wait for the turnaround but the guy I work with doesnt really have space to keep my car for a week or two at a time, would rather drop it off and have a replacement ready to drop in
