Hi All,

I have a few questions regarding a few things. I am relatively new to the turbo game, so excuse my ignorance :)

My R33 GTS-T is approx 5 weeks away (WOOHOO!), compliance under the new import scheme finally came through in QLD last week. I'm in Adelaide, I hope the guy in QLD will do a good job and is trustworthy. It's scary being so far away from my car and spending all this money without being able to see anything.

Now I have done a search for my following questions, I guess I'm after some 'laymans' answers as I am not as familiar as most of you out there yet.

1. Blow off valves. From what I can gather, the R33 GTS-T has one standard??? I would like to fit an after market one (I have to have the Psshhh! once in my life :() I was a fitter and turner and I do work on cars so I belive I am capable of fitting one, I just want to know where it is, what (if any) mods have to be done and what type of bov you all recommend. If anyone knows a link to some detailed instructions, it would be appreciated.

I have just ordered an R33 workshop manual ($250 ouch!), I will hopefully have it in a week or so (This will prolly answer most questions for me, but I like your opinions too).

2. I was reading the specs for the R33 GTS-T ('95...my model) on an autotraders website. It stated that it doesn't come with central locking. Is this true??? I did a search and found a lot of threads regarding the R33 locking itself at 25km. I want to arrange an alarm to be fitted prior to me getting my car, so I need to know if it will have central locking or not.

3.Is the replacement air filter in the R33 the same size as the R31? One of the first things I want to do when I get it it replace the eliment with a K&N filter.

4. When I first came across this forum I saw a comment (I think from the guy that hosts this site) asking if we could chip in financially to keep this site alive. I would like to make a contribution as this forum has helped me out so much and more than likely will do in the future. How do I go about doing this?

Thankyou for your replies

If I were you I would not get a BOV as they don't really do anything apart from make noise (and attract the cops). Also they make cars with a AFM backfire / run rich. And yes there is a BOV that comes standard but it recirculates back instead of to the atmosphere. The choice is yours some people say there are gains to be had installing a BOV, imo i don't think this is the case.

Welcome to the forums btw :)

get a bov if u want .. its ur car .. keep in mind the risks and hassles of having it thats all .. if ur car doesn't have central lockin which would surprise me, it doesn't cost much at all to put it in .. comes with most alarms .. make sure u get a good decent alarm though .. since i'm in adelaide, maybe u can lend me a ur copy of the workshop manual .. i'll make copies :D ... maybe u can just get a new air filter all together .. cost maybe about 200 or so for an apexi ..

good luck .. btw what colour is ur car?

this is the way i look at it, im on my ps driving a skyline, im gonna get coppa's attention no matter what and get pulled over every 2 seconds like i have been, so the bov doesnt bother me. i got the stealth skyline bov from go fast bits..

cheers..

Well if you purchase magazines like "High Performance Imports" and other such mags then you'll actually read that BOV does actually make a different. Since the air doesnt get recirculated straight back into the turbo slowing down the turbo fast hence turbo lag. A BOV releases that air so there is no slowing down of the fan and hence no turbo lag.

But the choice is up to you. Like everyone else says it attracts cops.

Cool there's another P plater with a skyline!

:burnout:

iBd14U, read up further how a BOV works. Recirculating BOVs do not 'slow down' the impeller on the intake side of the turbo; it is physically impossible that compressed air will slow a spinning impeller 'sucking' atmospheric pressure air on the inlet side.

Thank you all for your responses.

Scanning 500+ pages of the manual and converting to pdf...would take a while. I want to scan it anyway so I don't get it dirty when working on my new girl :)

I know some of you think that a bov is surpurfulous, I don't want to get in trouble with the cops either, I just love the sound :) I have enough dramas with the cops in my N13 pulsar GL ;)

Looked at ROH 17" Fury wheels for my car today. $2300 inc tyres. Gees, things have become expensive, it's been about 5 years since I've bought stuff like this, I am really out of the loop.

Hi terry...i know how u feel waiting for ur car heheehe

well i just got a BOV due blizt(the new one)...it cause me so much problem keep stalling on me..and no solit power...got rip by my friend evo3...that day.. so i took it off..and i can feel the power again...and no more stalling......after installing it for a day i took it off and put the stock one on...but i have to say BOV sound great

not for my car tho

good luck

    • Surely somebody has one in VIC. Have you asked at any shops?  Is this the yearly inspection or did you get a canary?
    • This is where I share pain with you, @Duncan. The move to change so many cooling system pieces to plastic is a killer! Plastic end tanks and a few plastic hose flanges on my car's fail after so little time.  Curious about the need for a bigger rad, is that just for long sessions in the summer or because the car generally needs more cooling?
    • So, that is it! It is a pretty expensive process with the ATF costing 50-100 per 5 litres, and a mechanic will probably charge plenty because they don't want to do it. Still, considering how dirty my fluid was at 120,000klm I think it would be worth doing more like every 80,000 to keep the trans happy, they are very expensive to replace. The job is not that hard if you have the specialist tools so you can save a bit of money and do it yourself!
    • OK, onto filling. So I don't really have any pics, but will describe the process as best I can. The USDM workshop manual also covers it from TM-285 onwards. First, make sure the drain plug (17mm) is snug. Not too tight yet because it is coming off again. Note it does have a copper washer that you could replace or anneal (heat up with a blow torch) to seal nicely. Remove the fill plug, which has an inhex (I think it was 6mm but didn't check). Then, screw in the fill fitting, making sure it has a suitable o-ring (mine came without but I think it is meant to be supplied). It is important that you only screw it in hand tight. I didn't get a good pic of it, but the fill plug leads to a tube about 70mm long inside the transmission. This sets the factory level for fluid in the trans (above the join line for the pan!) and will take about 3l to fill. You then need to connect your fluid pump to the fitting via a hose, and pump in whatever amount of fluid you removed (maybe 3 litres, in my case 7 litres). If you put in more than 3l, it will spill out when you remove the fitting, so do quickly and with a drain pan underneath. Once you have pumped in the required amount of clean ATF, you start the engine and run it for 3 minutes to let the fluid circulate. Don't run it longer and if possible check the fluid temp is under 40oC (Ecutek shows Auto Trans Fluid temp now, or you could use an infrared temp gun on the bottom of the pan). The manual stresses the bit about fluid temperature because it expands when hot an might result in an underfil. So from here, the factory manual says to do the "spill and fill" again, and I did. That is, put an oil pan under the drain plug and undo it with a 17mm spanner, then watch your expensive fluid fall back out again, you should get about 3 litres.  Then, put the drain plug back in, pump 3 litres back in through the fill plug with the fitting and pump, disconnect the fill fitting and replace the fill plug, start the car and run for another 3 minutes (making sure the temp is still under 40oC). The manual then asks for a 3rd "spill and fill" just like above. I also did that and so had put 13l in by now.  This time they want you to keep the engine running and run the transmission through R and D (I hope the wheels are still off the ground!) for a while, and allow the trans temp to get to 40oC, then engine off. Finally, back under the car and undo the fill plug to let the overfill drain out; it will stop running when fluid is at the top of the levelling tube. According to the factory, that is job done! Post that, I reconnected the fill fitting and pumped in an extra 0.5l. AMS says 1.5l overfill is safe, but I started with less to see how it goes, I will add another 1.0 litres later if I'm still not happy with the hot shifts.
    • OK, so regardless of whether you did Step 1 - Spill Step 2 - Trans pan removal Step 3 - TCM removal we are on to the clean and refill. First, have a good look at the oil pan. While you might see dirty oil and some carbony build up (I did), what you don't want to see is any metal particles on the magnets, or sparkles in the oil (thankfully not). Give it all a good clean, particularly the magnets, and put the new gasket on if you have one (or, just cross your fingers) Replacement of the Valve body (if you removed it) is the "reverse of assembly". Thread the electrical socket back up through the trans case, hold the valve body up and put in the bolts you removed, with the correct lengths in the correct locations Torque for the bolts in 8Nm only so I hope you have that torque wrench handy (it feels really loose). Plug the output speed sensor back in and clip the wiring into the 2 clips, replace the spring clip on the TCM socket and plug it back into the car loom. For the pan, the workshop manual states the following order: Again, the torque is 8Nm only.
