dude there a pretty solid motor. unliek the rb25 from the r33, they got solid lifters, top feed injectors, gtr rods (i think), diff cams and slightly better turbo (boosts quicker). only cons i know of are the fact the upgrade add ons such as injectors etc are more expensive for the neo lol

thanks heaps dude, but alot more ifo would be appreciated if anyone can help me out. :) the neo 25 has front mount, pod and exsaurst. and it go's ok what other mods would benifit the engine and what are there oil/water pumps like and what are they like for heating ( will i need a bigger radiator??? and things like that?

but thats for the help guys =)

    • What ECU is on your car @silviaz? You can just change the idle target table yourself and the IACV duty cycle. Noting that if you play around with the screw you'll also need to revisit the idle base duty table as you will end up offsetting the lot. Another reason why DBW is superior, there's less mucking about.
    • Yep. Saw that on the image above but, wonder if it makes more sense to clean out the iacv because let's say in theory mine is dirty and if I clean it the rpm will drop. If I first go to my tuner to drop the rpm and then go to clean my iacv won't it drop further or is the rpm a fixed number?
    • Yeah it was a good result, and confirming the car is full of fluids and all interior etc in, other than fuel. I think a few pages back (maybe many pages!) he mentioned some serious lightening in the doors with the chassis punch, might have been done elsewhere I hadn't seen yet too
    • He still had the suspension dialled in for him! I would have sworn the lowest weight he ever got to was 1300kg though Maybe Neil had been drilling a LOT of holes somewhere you haven't found yet... 😛 Or has he also drained all the gearbox and diff oil out too, between it, and a tank full of fuel there's about 65kg to 70kg to add back in I'd guess. 😛
    • Yeah this isn't a super complex shape, but I was still happy to buy instead of fab version 1; very little in a modern can is a flat surface, and that is true here again - the undertray has about 50mm in height differences that I would have had to work out myself. I will probably make something more substantial before it does any rally, I don't think 1mm steel is too much use as a bash plate. There is also cooling to think about, Z1 have done a bit of development and have some air holes and louvers in the shape, will see how that works out too
