I just want to ask a few questions..

1. What horsepower will a r32 driveline handle? I have a brass button clutch, so the clutch has been looked after already.. Im thinking around 400hp at wheels is what my car will have when im finished...

2. With this amount of hp, what sort of management system should i run? I was thinking standard comp.. aftermarket comp.. what would be the best for the job?

3. Where is the hicas fuse? If there is a fuse? Or, how do i kill the hicas, with out the lock kit? eg, for quick squirts on the track.

Thanks guys.. hope the questions dont seem silly.. and that i have this post in the right thread!

1. What horsepower will a r32 driveline handle?

Pretty hard questions to be answering as there are so many variables. Those mainly being how well driven/mantained has the driveline been, and also how hard/easy your driving style is on it.

300rwkws is a lot of power and i dont see a high km RB20 gearbox living at that power especially if you are going to do track work. So if, some will say when it breaks, you may need an RB25 or other box.

2. If you are looking at 300rwkw id personally be looking for n aftermarket computer, most likely Autronic or similar. They have features that will help engines live at this hp as well as being able to give accurate enough control over fuel & ignitoin in the 1st place.

Features like boost control, limp home function, cuts for when boost and water temps etc go past set point etc etc. All nice features that help an engine live.

3. On a 32 the HICAS is hydraulic (33s electronic) and i wouldnt recommend disconnecting the Hicas computer/pulling fuseses etc. This would result in a rear steering rack that has some free play in it when cornering which cant be a safe thing or a nice thing when punting the car quickly.

There are numerous local kits and Jap kits that range from an ECU by-pass and steering rack shims (Tomei) to a solid chrome moly bar which replaces the factory rear rack.

As for only disconnecting the HICAS for track work, i have had mine disconnected for some time and cant honeslty say i dont notice any difference on the street, but sure as hell notice extra stability on corner exists at the track. So i woudlnt worry about having to reconnect it for the street.

Does this help or confuse you? Sorry:D

with the 32s you can remap the std ECU, which on a budget would be your best option. having said that not many people successfully make 300rwkw on a budget so it may be best to look at an autronic

the HICAS system control can be found underneath the parcel shelf, just disconnect the SMALLER plug. i d/ced mine cos it would continually bring the light on and kill the power steering. i havent noticed any play through corners and for a RWD car pulls through the corners fairly quickly

I wouldn't buy an Autronic personally, me and a mate did some serious homework for his rb20 S13 and without a doubt MOTEC is the best in fact it is probably the best management in the world.

I suppose my comment isn't really fair about the Autronic...I just think that if you are going to push for 400rwhp then it will not be the best choice. My suggestion is to contact Cramer Dyno & Performance in Toowoomba (It is well worth the drive) and chat to Tim he is great with MOTEC, MICROTECH, UNICHIP and most other management options so have a talk to him (get him to do the work too if possible) email me for more info etc cam@urban-adventure.net

Sorry RB20 gettin rid of the sil soon chasing a gts-t type m and want to pull about 225rwkw maybe more depending on funds.

Hmm maybe scouring the wreckers isnt a bad move then as long as you know how to set it up, did u have ne probs get all the wiring etc??

I know where there is a couple of guys in wa that do remapping mite see about prices.

Install is easy....unplug stock ecu, plug in jap ecu, start car and go hard :D Not sure if they are all like this but I never had a problem....also got rid of speed cut and lifted rev limit by 500rpm there was no actual tuning involved and when I coupled it with a big pump and apexi s-afc I took power up to just under 220rwkw (remember that 220kw is the absolute max for stock injectors)

RB20 owners should all but forget about Power Fcs, they are a real find if you come across one, an even better find if they work properly (mine didnt)

Motec & Autronic are fairly equitable ECUs if they have the same software upgrades, only thing is Autronic works out a bit cheaper. My thoughts are your comparing a Bentley to a Rolls Royce, both are good choices with auto tune functions etc etc.

Other ECUs have their + & - but if the budget stretches to a Motec/Autronic then you cant go wrong with either.

As for the HICAS, i have replaced the rear steering rack with a chrome moly rack to which the tie rods screw into. The lines/pump/old rack were then removed/bypassed saving a few kgs, and still leaving the steering check light on the dash functioning. (A good thing)

    • I'm hoping I just don't have to do an engine rebuild NOW. Doesn't mean I won't do it at some point. I think a plus point is that the car presumably ran on or close to stock power nearly all it's life so far. Only the Owner I bought it from actually increased power with a standalone ECU and blew the OEM turbos. And after it got thee 2860s it wasn't driven an awful lot either.   That is what I meant. With the twins coming on so late (4500-5000rpm) I hope the rods won't want to exit the block prematurely. And it still being a 26 means the torque curve isn't gonna hike up all that much.   It didn't blow up on the dyno when they tuned it to 500ish crank. So I suppose it'll be okay for now. They did put a Tomei head gasket on first though which did not seal at all, and they redid it with a Cometic one. Which I hope won't be my water leak.   Mainly anything oil. So far all it has is the N1 pump, oil restrictor and a filter relocation kit with a cooler.
    • 15000? ish? Something like that anyway. It wasn;t so much a wear as a tear that then spread. Might have lasted a lot longer if not bothered by just one incident, whatever it was. I took a punt. They are really comfortable and do a good job of holding. My daughter HATED it when I first put them in, and probably still does now. She has sensory issues and hates the way they are all up your business. I'm 197cm and 95kg. Not fat or particularly wide, and the XL size seat is the rigth fit. If I was any fatter it would start to get too snug. Any skinnier and you'd possibly want the smaller width.
    • Mrs rs focus came factory with recaro cs  sportsters in it and they a pain in the ass to get in and out of with the really high bolsters, once you were in them they were one of the most comfortable seats I have ever sat in
    • The NA 2.5 has very little torque. You won't feel much. Those trannies are also a million years old now and it could well be f**ked. First generation electronically controlled autos will often refuse to kick down, ete, etc, depending on what's wrong with them.
    • Yes, but no but yes but no. Those "it's fine up to 500HP" rules and everything else like it were all determined back when the cars were 10 years old. As they are now 30 years old.....what do you reckon the chances of something shitting the bed are? I'd say they are much higher now than they used to be. You might be lucky. You might be unlucky. Spin the wheel and find out. Yeah, nah. It's actually exactly the opposite. Making boost early and having heaps of torque able to be generated right in the middle of the rev range will do more to damage an engine than having to rev it high to make the power. Think about the load on the conrods, bearings, etc, to make 400HP at 4000 rpm, vs 400 HP at 6500 rpm. So someone has already "let the Nissan out" which is how we describe the increased chance of a fiddled with engine to have had something done wrongly. Many more engines that have been opened die than stock ones do - even if you into consideration how they are treated wrt power levels and the like. Again, not saying that yours will definitely have been put back together by a moron. But the possibility does exist. It's still a lottery. Spin the wheel. What weakspots?
