Hi Guys,

This isn't really Skyline related, but I've had this idea in my head for a while, so wanted to ask it. I was going to ask it at Performance Forums in their Engine Conversions section, but they won't let me join because my Yahoo email (which I pay for, and is my only email), is not allowed.

I thought of this after reading the RB30DET thread. Basically, what I'd like to do is buy a VQ30DET engine and a VQ35DE engine and put the 30DET head on the 35 block - in the same fashion as the RB25/30 hybrid. Is this possible and has anyone done this? I haven't got the bore and stroke specs of either, but I'd assume the 35 just had a longer stroke. Is this correct? All the other bits like the rods and stuff should be able to come straight off the 35 shouldn't they? Having said all this, would it just be easier to buy the VQ35DE and turbo it using custom parts. The gearbox, I'm not sure on, but I would assume that the one they use on the VQ35DE would be fairly strong.

Also, if what I've just written is absolute shit, please don't be too hard on me as my knowledge of engines doesn't really extend into the internals. I know bolt ons only really :) Please tell me if it's possible though.

Anyway, at the moment, it's just an idea, but it's something I'd like to do in the future. I may just buy a VQ30DET from a Y33 or something and put that in the donor car (undecided at the moment, but I'm thinking an R34 GT, and the 2.0L engine can go into some shitbox).

Cheers,

Michael

Then again, I could either get a 350Z ($$) or wait a bit until the V35 coupes are available (too $$ for me too) and just put the 30DET head on the standard 35 block. That would mean a lot less work than a whole engine conversion.

What sort of turbo packages are available for the 350Z now? It's got the same engine, so I might be able to look at one of those. The reason I thought of just using the 30DET head was for cost, as it would be a lot cheaper than custom parts I thought.

      Need AC Compressor for R32

      By GTSBoy · Posted

      The Frenchy's kit is the way to go forward. A modern compressor that weighs about 1/2 as much, is at least twice as efficient, and will do a good job on R134a. And of course the kit has everything else you need to connect it up and have it work properly.

      Need AC Compressor for R32

      By Zabuza · Posted

      Hey all , I am in the process of having the AC system in my r32 GTST converted from r12 to r134a and I’m being told my compressor has gone bad and I will need a new one. I was wondering if anybody has any suggestions for what is the best route to go aside from dropping $1500 on a new oem one? I did see that Frenchy’s performance garage offers a kit to mount a Toyota compressor, has anybody actually used this kit on their car? Or is there anywhere I could purchase just a clutch? Any help is appreciated.

      Help Understand GTT Boost Setup

      By GTSBoy · Posted

      Well, your RB20 ECU loom won't have wires for the boost solenoid, that boost sensor, and possibly one or two other things. There could be differences in seemingly random things like the charcoal canister purge solenoid, because the 25DET has to handle boost in the vacuum system and the 20DE does not. I don't know - I haven't looked. It is very likely that all the most important things are same-same, being the main sensors like AFM, CAS, etc, and the injectors and ignition. Not that you'll need the AFM for the Haltech anyway. I would suggest that you would seriously want to sit down with the pinouts for both ECUs and just go through them and highlight green what is the same, orange what is different/missing, and make a plan from there. It's not going to be difficult. It will either be the same or need to be fixed.

      Help Understand GTT Boost Setup

      yeaaa that's why I haven't done any wiring to the stock ecu harness because I have the haltech, but then that leads me to the other question of "is the pnp harness really plug and play?" or would I have to still switch some pins/wires over because the pnp is for the rb25det neo harness, and not for the rb20de neo harness. was really hoping to find something to spoon feed me since so many people have done rb20neo + t conversions, but man this is rough.
