Yeah guys I have an Apexi Dual Chamber BOV that is suited to an R32/R33. Fully adjustable spring tension and 3 noise volume settings. It is a little scratched up but works perfectly. $135 plus fright.

Is the exaust housing ok?

Give you 80 bucks plus fright for it man.

I'll email em thanx. Nah havent tryed the zed forums yet

As title says. Thanx lads.

The turbo is from UAS and has a 0.48 rear housing. As for the front a/r I have no idea and I'm not sure about a part number. (Sorry I aint much help there). http://www.nismo.com.au/pricelists/General...skyitsturbo.jpg http://www.nismo.com.au/pricelists/General...kyitsturbo2.jpg Its a T3 flange that has an adapter plate made up to allow it to have an internal gate and to bolt onto the skyline dump. --------------------------------------My mods include----------------------------------- Trust BOV------------->Replaces the stock one and can be plumbed back if needed. Blitz intercooler------> 600 by 300 by 76mm ECU--------------------> Remapped to run 550 cc injectors and a z32 AFM(My personal tune on the conservative side) Pipeing in the engine bay is stock and really should be replaced with bigger less restrictive pipeing. Exaust is a 3 " turbo back system with a resonator, 3" cat, 5" ricey muffler Injectors are 550cc pintop rx7 types. AFM is a Z32. Boch 040 intank fuel pump good for 600 hp I think. I'll try and get some pics of the turbo and engine bay tonight if I can.

Yeah mate I'm kinda bad for that too.

You didn't offend mate sorry just real tired and cranky from the weekend. I guess that this turbo is probaly more efficient at higher boost levels and needs to be boosted high to get the big power. All I know is when it runs 20 psi the power difference is huge. That kick you back in the seat feeling is nuts. why its so laggy I'm not so sure other than the fact its a normal sleeve bearing turbo from what I can gather.

Geeze give me a break man. I haven't had a lot of time to do this and I'm sure I could get more power out of it yet. Got to remeber its not a ball bearing turbo either. As for why I went with this turbo? Decided to try something different and not follow the sheep.

I think he had an RB20DET auto ecu forsale at one point. He may be able to get one from it if you ask him. He's from the Ztech forums champ.

Well I am fairly happy with the dyno result from the Ingham car show. 299.99rwhp @16-17 psi running a 11.8 afr. I didn't have the boost controller set up for 20 psi at the time but I am really happy with the result. Few of the V8 boys were startled buy that. I dont have a dyno graph yet but I will be talking to TMS sometime this week to try and get a run on the dyno (one used in car show) at 20psi some time.

http://forum.ztechz.net/ Should be one on there somewhere from memory mate. As Darkhalf as he may be able to help too.

Hope this can help mate. These are from the apexi site.

Interersted in the head and the inlet manifold if you have it?

Spose you have sold those springs now man?

Still road tuning but I will have it on the dyno next week at the Ingham car show. After that I will probs get it on a dyno again to just teak the maps a bit.

Thanx for the advice mate. Dunno what I will do yet though.

Exaust could be a little bigger I guess. 80mm atm primary muffler too. As for intake its not all that freed up either. Need to get some pipework done soon.

Yeah nmate how much for 25DE head.

OK I have done some thought. If I run a slightly richer a/f of say 11.7 (what I am now) the temp of the exaust gases will stay fairly stable. If this is the case I would expect I could run a decent amount of ignition advance. Obviously to much and it pings and then the temps raise right? So if I set my knock map on my ecu to run say 3 degrees lower than the main map if it does ping the ecu will switch to that map. (It does. Tetsed a few times from boost spikes while setting up bc)3 degrees would /should avoid knock then I guess. Conzult also spits out a knock code when this happens even when I didn't Hear any knock. Gotta love knock sensors. :inlove: If this works as i should I could have a very reliable motor at high power levels. As long as something out of bad luck doesn't go wrong of course. The motor was bouht from a forum member and he didn't have it boosted too much at all from what he told me. He did the water pump and a new cam belt within 5000kms of selling it to me. I had a leak down test done and it had less than 5% leakage at all six pots. So its fairly happy I guess? If the Rb20 is over filled with oil a bit this should help things too. Don't seem to get any extra blowby and I cant see why this wouldn't help to avoid oil starvation? Also if teh engine is kept from knock surely i could take a fair bit of power? 250rwkws? Sorry about rambleing on. I just got adsl going tonight and I am a little keyboard happy.

The a/r on the rear housing is .48 and I till dont get one bar till 6 grand. Hey thanx for the links I will have a squiz right now.

Nice!! I might bump the rartio up to 11.9:1/12:1 then.

The oil I use is penziol 5w50 fully synthetic and it seems to be pretty good. My ecu is the stock ecu that I have recalibrated and remapped to suit the new injectors and my new turbo. Its tunned great for up to 16psi but it pings very slightly if I go any higher atm. Just running a little two much timing at that point which I will rectify on the weekend. I do like to try new things and be different so I chose the ITS turbo (Pic in my Avatar) It seems to be a very good turbo but I think it was more designed for the RB25 though. Do you think running 12:1 at 20/22 psi would be ok? What is the max power level the RB20 will take reliably? Once tuned I will let you all know how it goes.

Ok I am about to give my R32 RB20DET its final power tune. The motor is in good health but is stilll stock. My mods include-----> Blitz front mount, ITS turbo, RX7 pinktop 550cc injectors, 3" turbo back exaust. Z32 afm will be added before tune aswell. I wish to run 20psi and I would like to know what ratios would be good for power but not too lean. Atm I run 16-17 psi and am running 11.7 a/f and run 24 deg btdc from 6500 to 8000rpm. If I winde another 3-4 psi (aka20psi) will I need to run a little richer to keep the exaust temps down or should I be ok at 11.7. I would expect about 230-240 rwks at this level of boost. Thanks guys.

Its hard to say really. I am using bigger injectors now and I get a little less economy but I do have a bit of a led foot though.
