Hi Guys,

I have just bought my first R33. Yesturday the rubber pipe broke off from the boost controll and my boost was hiting (whats looks to be) 5 on the in dash display. before i this happened the boost was only getting up too 1-2 on the display. What is the standard boost the car should run. I have also been told not to boost the stock turbos as the fins with break. :P..

The car has a boost controller but its turned all the way down.

How much would a after market turbo cost?

Thanks for the help,

Kyle

Hey buddy

Stock boost is about 7psi.

Have a read through the forced induction section of the forum, you will find heaps more info there :P

You can boost the stock turbos up to no more than 14psi which is what is recommended, but thats with supporting modifications such as FMIC and turbo back exhaust.

It should run on or around that line between 0-7, and a turbo upgrade can cost from 1-5k for something good!

I think high flow'd turbo's are around $1700 all up, but there not gonna do you any good with the stock ecu.

Thanks guys, its a good place to start. how much would a good turn cost, I was speaking to a guy on the Gold Coast and he said he spent arund $700 for a dyno turn,

What does FMIC stand for, Sorry for the stupid questions but im new and its the best way to learn. lol

Where could i find instruction on how to hock up a boost gague.

Thanks in advance.

You'll need either a piggyback ecu or replacement ecu to be able to "tune" anything at all. Otherwise the most you'll be able to do is adjust ignition timing which is hardly worth paying that much money for.

A good dyno tune will normally cost around a minimum of $150 just for the tune. The $700 you mentioned would have included extra stuff, and maybe tuning more than one thing. I've only had a Apexi SAFC piggyback tuned which isn't that hard so cant give you a good estimate for say a full replacement ecu sorry.

FMIC is Front Mount InterCooler. You should be able to find some good info on these forums by using the search button... :P

there is a small nozzle on the back right hand side of the engine (if you're facing forwards, or left if you're at the front of the car looking in the engine bay) - it has a small rubber thing on it to block it off - you just remove the rubber stop and connect your boost guage hose to that nozzle. as for mounting it etc. well thats a bit more difficult and entirely up to you...

generally, if you're not sure, get a friend or workshop to do it...I'm kinda in the same boat as far as my technical ability. I know how to do fairly simple stuff but I'm no mechanic. :(

Oh, and stock boost is 5psi up to 4500rpm where it increases to ~7 psi. But if you've replaced the stock boost solenoid with a boost controller you'll probably want to set it anywhere between 7 and 10psi but no higher than 10 to protect the stock turbo. If the turbo shatters (which it will at anything around 14psi) it'll cost more than just a replacement turbo...

Like others have said, to make an aftermarket turbo worthwhile, you'll need to spend around $5K including the turbo itself...and maybe more to get the best from it...

    • Oh and I lost my headlight washer jet cover!
    • Ok, so I got myself some X1 wheels really cheap to try out, they're a bit different and I like them but they're really narrow (18x8) they are available in staggered 18x8/9 also but really hard to find.  I kinda dig them, but not as much as the F10 19's I usually run, so these go into the wheel pile.   As I mentioned in another thread, I got a new exhaust. It's an off-the-shelf stainless one that fits OH-KAY. I don't love the tips size and how far they come out the back, I think I might cut the tips off and replace with some smaller (~3") ones that don't extend as far. It sounds really good though, I'm not sure if its just in my head but the car feels a little quicker, more responsive.    I fitted an eBay special front lip. Surprisingly it fit perfectly and all holes lined up. Its a little rickety but I haven't put any double sided tape on yet, I want to clean the front bar up where it has scraped the road a lot and fil in the number plate holes (or, get body coloured wrap to cover them - is this a thing?  I'm not sure if I'll leave it gloss or pain it matte. I really like it though, I don't particularly like the front bar without it, I don't really like the M-Sport and to get anything else is just too expensive. That said, I might need a new one now anyway as I dropped the car onto the jack after forgetting to put ramps under the front wheels. It bent a lot and while it did go back to normal after I got the car off the jack, I do fear I have not done it any favours.   Lastly, my headlights died. Different problems in each. They have gotten much dimmer over the past year or so, I put new (uber expensive) OSRAM bulbs in them but to no avail. One of them pointed at the ground and the other just kinda did its own thing with light working sometimes. Yeah, check this 18 year old BMW headlight wire. I reckon I know why they were stuffed.       BTW, the yellow and black is the power to the Xenons. Yikes. I hunted around an researched my options here. I would have loved to just get a replacement harness but not a thing. My car has adaptive headlights, that is they rotate left and right with the steering wheel. Good condition used adaptive xenons were over $700 each, non adaptive were around $400 each, but I couldn't help but think that they're all around 18 years old now, surely they'd have the same problems. So I looked at newer LCI headlights but they were even more expensive and I couldn't confirm that they'd be plug and play with lots of people having lots of opinions so not worth the risk.  I ended up getting brand new Chinese headlights from MARS. They're very close to OEM with only the angel eyes being a bit different. I didnt want crazy turn signals or sharp DRL's or anything. Not my bag.  They're not adaptive, I thought thats a feature I wouldn't really miss. So I coded that out.  The lights are awesome, they look so nice and they take so many years off the car. The angel eyes look great and the headlight brightness is ridiculous. I was so used to the old ones, I didn't realise just how bad they were. The new ones use the OEM bulbs, Xenon ballast and leveller motor which I was happier with. The only issue with them is that the rear cover is held on by SEVEN screws. This will be a nightmare to get to and open when I need to change bulbs.  
    • Now that you mention it I can see those too. More subtle. The lighting and low resolution makes it hard to assess super well what's going on but what is visible is bad enough to pull the motor.
    • I feel like this is due an update
    • Yeah, I wasn't giving two f**ks for the ring running around the bore. I was looking at the vertical scratches running up and down across the hatch marks.
