4'' body cat is too small for a 4'' system Usually you will find a 4'' body on a 3'' cat or a 3'' cat that has been necked to 3.5''

1 get ID's unless you can flow match the bosch injectors. ID1000 should be ok for only 400 rw kw 2 pretty sure RB26 use different pullies to RB26. Water pump and alternator should line up at the very least but the power steering wont 3 4'' all the way minimum. Finding good 4'' mufflers is a prick as they are all expensive, if you have to step down do it after the diff. You can also split it into a duel system but there isnt always enough room

Is it possible to adapt the GTR sump which will solve your 4wd front diff issue?

im guessing jonno is running a pfc with datalogit and using "average" setting that averages out afr which is why he is seeing only half a point. Try a log in 2nd gear using the min setting, then the max setting (going through your 5th gear cruise load zones). Repeat with a log in 5th on min and another on Max and compare logs. The difference should be around 2 points. If you want to get anal about it, do it on the same day, same stretch of road etc. Im not arguing that you cant find an acceptable compromise, but remap it so its not as lean in 2nd gear and run through those load points again and tell me how much stronger the engine is ;-) Problem is when your in 5th you'll be running a bit richer then an "economy" afr. So a compromise has to be made MBS im running map based which is a little different to afm off boost but, pretty much the same once you see a bit of boost. Once on boost, load is load, doesnt really make much difference how the ecu calculates it. We already discussed that its possible to use common load zones when more power is required then an economy. Lets break it down slowly. Say your in 5th gear at about 2k rpm at around 65-70klm, light goes amber, put it in 3rd and nail it to get through before it goes red. Your at 3k rpm now, low load since your turbo/s are spooling, you might even be at a few psi boost. Your now in the exact same load zones as you would be if you were in 5th gear at highway speed limit. If your tuned for best reasonable economy for 5th at 110klm its lean what you have just done in 3rd. The engine still see's the same load but the only thing that has changed is the gear selected, well you just changed the mechanical leverage the engine has to deal with but the engine is still seeing the same engine load at one point and crosses through a part of the map (and its interpolated zones) that is tuned more for economy and runs leaner then optimum power. No big deal, its not gonna break since your only on low boost and its run through it quickly enough Im not saying you CANT find a compromise, you can! I know where youre coming from, because in theory Load is Load, but its not that simple. If you look a little deeper into it things start to clear up. If you play around with it, and see for yourself you it will be easier to understand where im coming from. Look at it from another point of view, a pfc has a 20x20 map for ALL gears and that is optimum!? Even though the gearbox allows mechanical leverage to differ which allows the engine to process fuel at a different rate. 5 different rates to be precise (or 6) If you ever get the chance to look at some of the late model factory ECU's, some of them have a compensation for gears for fuel, ignition and even cam control. Some even have a 3D map for fuel enrichment, RPM Vs TPS so light throttle changes can be economical still but when nailed enough trim can be made for power. The flexibility allows a lot less compromise!

p5-7 is all of my cruise points on no6. It will reach up to p10 on hills, overtaking etc. All the cells interpolate around those zones too Are you running a good high speed wide band? Could also be the way its mapped. If I run a map more to build boost quicker there is less of a difference but its still about 1 point. Its not so noticable if your just running through the gears but is clear as day if your say going through a series of S bends especially up hill and only in those load zones.

I guess your stuck then between stock and the chinese crap. I dont think its even possible to have a nice collector/runner in the stock position

log style manifolds are crud try and find a hks cast low mount manifold. They look stock enough

Could still be fuel surge if it was a right hand corner...

Is the law still stating that the cat must be in the same position as the stock cat?

So this is your highway cruise afr or is this your arf around suburbia around 50-80kph?! Highway cruise speed at 110kph will also use the same load zones as when your in 3rd gear and squeeze the throttle on from 2800 RPM. Even if you stand on the pedal depending on turbo charateristic. Unless im seriously mistaken the PFC doesnt have a gear compensation to run it richer in lower gears! So if your running 16:1 afr and 50 deg at highway speeds, in the case of a 3rd gear roll on your now running somewhere around 18:1 AFR and 50 deg timing and it will det. Unless your running really low comp. Admittedly rescaling will help but there is only so much you can do until you take load zones from other required parts of the map. Its not like most wire in ecu's that have a higher resolution if needed Its possible, easily possible especially on larger turbo's. Load it up on a dyno from low RPM for a power run and you run easily run through some of the cruise zones. The turbo/s are trying to spool on low load and since you have more cruise/economy settings its showing less then favouable results (down on power). Punch in settings to bring the turbo on quicker and your economy suffers. Its one of the reasons why some people start at higher rpm/load- so the graph simply wont show how badly effected it can be. I agree that it doesnt effect your upper rpm load zones but in this situation it will effect your mid range power/torque on a graph. It can bear a massive difference to mid range if you have a small engine massive turbo type set up. Similar isnt the same as exact Yeah but this will result in pretty "typical" economy. Not "exceptional" which is more along the lines of what I was talking about. Dont get me wrong, I know what your trying to say and get where your coming from, but from what I gather the OP does a shit load of klms. Typical highway fuel consumption from an RB isnt that great. Compare it to a 2.5 or 3.0l BMW on the highway which can do as little as 5-7 L/100 and 7.5l/100. I gooled the 3.0l as I never driven one but when you do a stack of interstate travels it adds up when fuel is $1.60 ish per litre. In the case of the OP, a multi purpose car he might be better off with a more advanced ECU, or a 2nd map just for highway use. In the case of using a power FC you could use a data logit to switch maps as needed. Heck if I did that many klms I could probably justify a map soley for highway use. Rescale the map for 4k rpm, lowest peak boost needed for overtaking/big hills along with a less aggressive boost curve. Maybe even water/meth so you could run decent timing/egt's while running it still pretty lean for the times you do need to run it into boost. In this case normal unleaded might even be an option with water injection since the 3.0 offers additional torque. Its almost excessive for highway use hence you could dumb down the tune quite a lot in the interest of economy

You would probably easily see 900klms if soley tuned for economy for highway use Dont know about you but I used to get 480klm on a stock ecu in suburbia driving like a normal person Dont get me wrong, back in the day PFC's were OK.....8 years ago lol. Would I change mine? well less is more at the moment.

say at 3K rpm which is about where 110klm is on the highway Best economy might be around 16:1 with light acceleration enrichment Best off boost power might be around 14:1 with more enrichment then the above Or it could be around 13:1 with a bit more timing then above The Map area you cruise in isnt usually where you run on full load, (but can be) but it is in a zone where you go through and near a lot in normal every day to day driving when you are going through other gears. Constant Rpm and Load is only 1-2 load zones. Slight up hills are another 2, bigger hills are another 2. So you might only use say 6 load zones on a PFC (for E.g) if your REALLY trying to be econimocal. The ECU interpolates so you need to compromise the zones around it for a total of 18 load zones. For simplicity reasons I wont bother interpolating any more. So you now have this big hole in your map and it runs leaner in the lower gears. Not so bad if you have extra capacity but annoying if you have stock capacity and bigger turbo/s. This is one compromise. Most aftermarket ECU's have 1 enrichemnt at 3k RPM. Running f**k all is good for economy, but if you come to a big long hill, switch to 4th as you start to loose speed, still in the lean part of the map, switch back to 3rd and nail it just to get to a different part of the map where its actually mapped for power. This is a compromise Because your running f**k all fuel in these 18 load zones your forced to run Less timing. Less fuel is better for economy but as your railing through gears in suburbia just to keep up with all the auto commo's etc you now wish you had more fuel so you could run more timing and overall have more power. This is a compromise too. On top end ecu's with a lot of time spent on the tune you can get a better compromise, even with a shit ecu like the pfc im using atm an acceptable compromise can be made. You can dam near double your mileage if you specifically tune for it. It involves really lean mixtures, realy shit timing and hardly any enrichment to the point where you can feel the car surging for fuel when you go up a hill with an incline of more then 3*

Its a massive compromise to have one tune for everything and doing so is time consuming. It nearly works out easier to have a totally different MAP for highway/economy driving you cant always have cake and eat it too

fastest I have ever been around a round about was in a TME. Their yaw control works well!

where does the gizzmo one go and how thick is it?

air con is for ricers

it would be futile

hmm I only have one that needs a rebuild $300

Been watching this for a while. Its interesting! I have a Q for you, what size ID are your manifold runners. I dont think it was mentioned before

Evo's are great cars. In practical day to day situations they are more useable then a GTR

the older you get the less attractive screamer pipes become
