Re: i just wanted to say i bought one of these last week and arrived today.. installed fairly quickly but as i had a few beers while working on the car as i work 12 hours and they where well needed lol i havnt given it a good test yet.... YET so ill see how it goes... as I'm fairly stock At THE MOMENT I'm not expecting much but as they are hard to come by for the t30 these days i grabbed it. especially after i read the 30+ pages relating to this.. so next step for my exy is to give it a lift in the belly..

Does anyone know if the TBS discussed here for your 2.5L engines would fit the 2.0L QR20DE engines that the exxys have in the UK. I've done a little research and from what I can see the intake valve head diameter on both engines is the same. I figured one way to find out would be to check the parts numbers for the throttle body for each model and see if they were the same, but all the links I've found to parts catalogues online have been dead'uns and a lot of Nissan dealers here are more interested in $$$/£££ than helping.
As there's a US supplier still selling TBS kits for the Sentra (which uses the QR25 engine) I would be interested in making this mod while the parts are still around!
Any thoughts/comments anyone?
p.s. I should have said, that if the TBS is compatible, I'd rather know and get it fitted before I install a strut bar, there's little enough wiggle room in the engine compartment!
I am considering ordering this for my QR20DE. However I suspect the performance gain will be much less noticable. Considering displacement, the QR25DE is pretty softly tuned compared to QR20DE, and as such mods like this are likely to make more of a difference. Are there any recollections from X-Trail owners that have done this mod to a QR20DE engine?
Currently I can push fuel economy to 6.9l/100km with an average speed of 75km/h (cruising in 5th gear), and the engine has an impressive torque in the low end of the rpm scale compared to other 2.0 petrol engines I have tried. I don't want to ruin that (:
Also thanks for a very interesting forum! You guys rock!
I just wanted to chime in with some QR20DE results; there does indeed seem to be a noticable torque improvement in low RPM. I don't think acceleration has changed, however the engines ability to keep the cruising speed (uphill) seems in fact to have improved, especially around 80-90km/h in fifth gear. I have a couple of "problematic" hills that always give predictable results (loss of speed, no acceleration), and there is a definite measurable difference. I am rather happy about this mod actually.
Besides the TBS I have a K&N filter and Denso iridium spark plugs. My current tires are standard size, 215/65-R16. Oh, and manual gearbox.
I suspect that this mod has more impact the colder it gets, since the throttle body doesn't seem to get warm anymore. It is currently about 0 celsius here, so I will report back after trying this out on some cold days as well.
As for why this works -- I think it must have something to do with intake length?
Re: Throttle body spacer G day
Im just about to purchase tbs for my T30
i read through the complete tbs section and cant find where i saw the link for the obx tbs and exact pt number.

Re: hiclone or throttle body spacer Hi all
Mat from the Central Coast .Hiclone or throttle body spacers what would be better spent on to inprove fuel economy when towing .I find when towing the camper trailer it uses a lot of fuel . if throttle body where do i find them for sale
Thank you Mat
