Hey all I have a standard R33 series 2 and I want to do it up but nothing crazy mostly for some performance and looks. I am planning three mods which I feel are enough for me but I want to make sure they are ok to do without having to get new fuel pump,injectors,ECU etc. I just want to bolt on 3 things and leave everything else stock and keep my car running good and not decrease the longevity of the engine. The mods I am planning on doing are as follows -

1. Full Turbo back exhaust with split dump and GTR Cat.

2. Hybrid Gt Spec FMIC kit

3. Panel air filter

I have been pming one of the members here and he has been great. I just want to see what the rest of the forum has to say. Also another thing I have been told the dreaded heatsoak can come into play when you install an aftermarket Exhaust and FMIC, is this true and would you recommend the application of heat wrap to the Exhaust and FMIC.

I think i covered everything I wanted to know. Any help would be great thanks.

I personally don't like the intercooler piping going back over in front of the engine above the fan but apart from that, what you have described is fine.

As for heat soak, I wouldn't worry about it for your desired level of performance.

yep, sounds about right for first round of mods, go for it :(

is very similar to what was done to my 33 first, should get you a decent gain and set you up for further additions in the future.

car may be a bit less fuel efficient but shouldn't alter reliability

Sweeet!!!!!!!!!!!!!!!!! Cant wait!! Oh yeh I was doing a little reading and in a hot 4 mag it was saying having a Large FMIC can cause overheating as the radiator is being denied cool air . Whats everyones opinion on that. As my last silly question at what stage do I need to look at Upgrading ECU,Pumps and all the other fun stuff???

I don't like the idea of chopping the fan blades as others have done to clear the intercooler piping. If this is an issue I suggest an electric thermo fan. They work great and don't get in the way.

If you keep the panel filter you can hook up your own cold air intake or do this. Pics below (hopefully). The air intake has been cut-away and some heavy plastic "welded" into place. Looks like it was always like that.

exhaust is good, fmic is good, air filter is good as youll keep the standard air box. you should now look into a piggyback system and a boost controller. run it at about 12psi and it should net you around 160-170rwkw which should be a nice and fairly quick streeter.

The piggyback apexi safc should set you back about $400 and $150 to fit and tune and $250 ish for an electronic boost controller. the biggest improvements come from the split dump / hiflow exhaust and the piggyback (if you get one). all in all looks good and should give some nice results fairly cheaply. Have you brought/paid for any of these parts yet?

sorry i missed

> Whats everyones opinion on that. As my last silly question at what stage do I need to look at Upgrading ECU,Pumps and all the other fun stuff???

you don't need to upgrade the ecu but you will certainly benefit from the change. i can't recommend the apexi powerfc enough ($1500 fitted and tuned). the car will drive amazingly better once fitted and you get rid of all the stock limits. stock fuel pump should be ok as long as you dont go over 12psi ish. any more boost pressure will risk the turbo and could lean it out also if the pump can't keep up.

you may find the stock clutch will start to slip once you do these mods however (i did anyway).

-= piggyback vs replacement ecu =-

-= apexi safc =-

price 550

pro cheap, good bang per buck

cons only alters air/fuel, limited tuning

-= apexi powerfc =-

price 1500

pro full engine management, no stock ecu limits, fully tunable

cons expensive

most people just go straight to the powerfc given the cost of the apexi safc and tune and fiddling around you could just go that little bit more and get a much more driveable car. also comes with the standard hand controlller which kicks ass

if you have any questions on the powerfc have a read of:

No I havent Paid for any of this yet. Im still asking questions to make sure I dont shove it all on my car and then start having probs. Im alittle confused now. Your saying I should look at a piggyback system and boost controller. I was under the impression I wouldnt need a Piggyback system for A FMIC,Exhaust and panel filter or do I need one now???. This is why Im asking so I dont do the wrong thing. Im not intending to go for a full rebuild and make my car as fast as most of you guys. All I want is the exhaust for the sound and power,FMIC cause I love the look of it and power once again and a panel filter for that extra power and induction noise while still using the standard air box. Funny enough Im not interested in boosting the car because by having the exhaust system the turbo is more efficient and I get a couple more PSI anyways and that would be heaps for me so I dont want a boost controller. But do I need a piggyback like the S AFC or power FC for these 3 mods or is the factory ECU capable of dealing with this comfortably?? Ive been told the ECU can "self learn" and detect the new mods and manage them. Thank Again for your responses this is great.

You don't need anything extra. As a matter of fact you don't need anything for a nice quick street car.

Some modifications point to, or actually require, other modifications being done.

Your 3 mods will improve overall performance and the standard ECU will not be phased by them.

Does everyone agree with this??

yes, that would be the consensus

can't say enough about the Hybrid GT FMIC... I was very impressed by the build quality and price and gained a healthy 30rwkw without noticable overheating or lack of throttle response... a good choice for you I think... although if you want limited modification and have a bit of cash to spend you could opt for an ARC FMIC that hooks up to the standard piping = no cutting

Interesting concept, just an FMIC, panel filter and an exhaust. Not much of a power increase there, maybe 20 rwkw at best. The real power increase from a turbo car comes from increasing the boost. There is at least another 25rwkw available from increasing the boost to 10 psi.

I achieved a 30 rwkw increase from the Stagea RB25DET by tuning (DFA) and boost increase (IEBC) with zero mechanical mods. That's why mechanical mods and no tuning seems a strange choice to me.

Whatever floats your boat

:D cheers :)

Noticable overheating?? I thought the whole point of the FMIC was to decrease heat?? How can you get overheating when adding a FMIC????

Because the cooler restricts airflow to the radiator.

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
