fake ben taylor Posted July 18, 2016 Share Posted July 18, 2016 Hey guys! As some will know Ive been working on a larger throttle body kit for the DE engine. NWP do make a kit already and mine is based on that but with shipping, customs etc it seemed to me to be overly expensive for what it was. Ive not done back to back dynos, nor do I plan to, as I would never recoup those costs and NWP have already done all that and theres countless discussions on it on the american forums Ive designed a plate and had one made and this is now fitted and working on my car. this is the kit - 75mm throttle body, adapter loom and conversion plate 2016-07-15_11-59-46 by ben taylor, on Flickr and this is it fitted IMG-20160715-WA0041 by ben taylor, on Flickr Note for testing I used a second hand TB, the kit would include a brand new one. So I'm asking who would be interested in the kit. The guide price I'm aiming for is £250-£300, but this is only a guide as I've yet to discuss how much getting the tb's, plates, looms etc will be in bulk, hopefully the lower end of that scale So, who's interested? 1 Quote Link to comment Share on other sites More sharing options...
Toon Chris Posted July 19, 2016 Share Posted July 19, 2016 How about a link to, or some info on, possible gains? 1 Quote Link to comment Share on other sites More sharing options...
fake ben taylor Posted July 19, 2016 Author Share Posted July 19, 2016 http://www.nwpengineering.com/Phenolic_Spacers.html#BBTB There you go there's also YouTube reviews etc In a nutshell the oem intake system is restrictive on the VQ engine, and is why on the HR Nissan doubled up. Increasing the tb size helps the engine breathe better higher up the revs. Adding a larger afm and intake pipe further helps that This isn't going to add peak hp numbers but should help area under the graph higher in the rev range And will also help on boosted cars by putting less strain on the turbo/supercharger Quote Link to comment Share on other sites More sharing options...
StevoD Posted July 19, 2016 Share Posted July 19, 2016 Make sure you get a big intake pipe and Maf to go with it or expect none-little gain Quote Link to comment Share on other sites More sharing options...
GrahameJ Posted July 19, 2016 Share Posted July 19, 2016 NWP's own dyno graph in the link shows it makes less max power and less max torque than standard, but does improve over stock from 5700 to 6200 revs. Any ideas why it loses power compared to stock at around 5300rpm?

fake ben taylor Posted July 19, 2016 Author Share Posted July 19, 2016 I 'think' it's due to the velocity being less through the tb (due to bigger size), and velocity bumps torque so that's why it drops slightly there, but what you lose there you gain later creating a quicker car, just less of a pub hp figure. It is a piece of a puzzle though, as someone else has said, a bigger afm and intake pipe help further. I do have one of those under construction for myself in 3.5inch flavour. Coupled with my long tube manifolds this 'should' see me to 290-300 at the wheels with just bolt ons quite a jump over the usual plenum spacer, 06 airbox etc getting 300 at the fly....

russyb Posted July 19, 2016 Share Posted July 19, 2016 (edited) As you know ben I'm very interested in this and would be happy to post my dyno figures in September Edited July 19, 2016 by russyb Quote Link to comment Share on other sites More sharing options...
djtimo Posted July 20, 2016 Share Posted July 20, 2016 Very interested in this.... May be a winner on a FI motor!! Waiting for details! Quote Link to comment Share on other sites More sharing options...
davey_83 Posted July 20, 2016 Share Posted July 20, 2016 I would be interested with UK dyno back to back dyno figures either from a forum member or the yourselve. Also you'd sell more kits if this was done on this side of the pond too. Quote Link to comment Share on other sites More sharing options...
fake ben taylor Posted July 20, 2016 Author Share Posted July 20, 2016 Problem is, I don't run a parts business, and no intention to. I wanted the bigger tb and put the work in making the kit so that I could have one without paying NWP prices, part of the reason I didn't opt for a brand new tb. As such I don't want to spend money proving a product that it doesn't matter to me how many I sell or don't sell. I've only offered it up here as it seemed like quite a few were interested. I hope this makes sense and I don't come across as a nob, but why should I go out of my way and spend my money for your guys benefit? I'm happy there is gains to be made when this kit is used as part of a bigger puzzle, and some mild gains higher in the revs when its just a stand alone item. If others are interested I can get some more made, if not, no big deal 1 Quote Link to comment Share on other sites More sharing options...
GrahameJ Posted July 20, 2016 Share Posted July 20, 2016 Maybe just supply the adapter plate and connector loom for cheapskates then, so they can use second hand throttle bodies to try this out? Quote Link to comment Share on other sites More sharing options...

Smc1992 Posted July 22, 2016 Share Posted July 22, 2016 I think I would be interested in this but would like to see a before and after dyno of someone who has done it so I can decide whether its worth me doing it or not. If its any help and there isnt a massive demand for them, I could have the adaptor plates CNC machined at my work. Quote Link to comment Share on other sites More sharing options...
350jimbobz Posted July 22, 2016 Share Posted July 22, 2016 What size is the standard intake pipe? Quote Link to comment Share on other sites More sharing options...
davey_83 Posted July 22, 2016 Share Posted July 22, 2016 ID is 80mm Quote Link to comment Share on other sites More sharing options...
fake ben taylor Posted July 22, 2016 Author Share Posted July 22, 2016 I know the arm is 65mm id with the maf stuck in the middle to further harm airflow Quote Link to comment Share on other sites More sharing options...
russyb Posted July 26, 2016 Share Posted July 26, 2016 I'd also be interested in just the adapter plate and loom if that makes it easier ? Quote Link to comment Share on other sites More sharing options...
fake ben taylor Posted July 26, 2016 Author Share Posted July 26, 2016 Would save me ordering the tb's from the states So yeah its definitely an option Quote Link to comment Share on other sites More sharing options...
Max-Read Posted July 28, 2016 Share Posted July 28, 2016 Looks good! Anyone have any ideas about how hard is it to get hold of a replacement pipe to cover the size difference? defo interested, more info the better Quote Link to comment Share on other sites More sharing options...
russyb Posted July 29, 2016 Share Posted July 29, 2016 Looking forward on this ben but I hear the x-trail has the same Thottle Body as the maxima do you know anything about this as it may be easier and cheaper to source the tb's Quote Link to comment Share on other sites More sharing options...
fake ben taylor Posted July 29, 2016 Author Share Posted July 29, 2016 I had not heard that, I'll have a look Bloody good shout if it is the case! Quote Link to comment Share on other sites More sharing options...
Stemo Posted August 16, 2016 Share Posted August 16, 2016 I would be intrested only in adapter plate and loom aswell incase you will decide to sell them separately. Quote Link to comment Share on other sites More sharing options...
