I have a GTST 96 model and have just put a saber intercooler kit on and replaced hot pipe and crossover pipe (top pipe) to inlet. I have also put on an apexi pod filter and the BOV on. The only other mod is the exhaust; from cat back, everything else is stock.

The problem i am having is the BOV fitted does not have a soft or hard setting therefore will not open properly, i have been advised to cut 15-30mm off the valve spring but am not sure if this will fix the problem or cause further dramas??

Can anyone HELP!

Maybe a replacement spring for this valve is available?

cheers guys

cutting it will make it stiffer, less coils makes a higher spring rate... yet perhaps its too long :S

i dont understand tho, the title says TIAL 50mm copy, which makes me think you mean a external WG, but your talking about a bov?

More info is required, and explain what is not working properly

Or you could put the factory one back on there, won't cost you a cent and will work fine.

I mean fair enough you've changed it (you should have used a GTR one)... but to change for a copy? Thats silly.

Cutting the spring might work, but totally depends if its now to short and won't seat properly, rendering the BOV totally useless with the chopped spring in there

Its a tial 50mm BOV copy (non genuine) it was actually given to me. Still factory turbo and wastegate.

Since the modifications mentioned in my original post the BOV will not open properly, we think maybe not enough boost for this size BOV. But we dont want to up the boost just yet as still standard turbo and dont want to damage anything.

Pretty sure even genuine Tial does not have soft hard setting, already had custom top pipe made to fit this BOV, so would have to have another top pipe made to change BOV if thats what your suggesting.

Really just curious if i can get a replacement valve spring with correct spring tension to make this BOV work.

Cheers for your feedback

Hi,

Unfortunately as i have changed the top pipe i will have to put stock one back on to put stock BOV on.

My boyfriend got this work done for me and I only found out today it was not a genuine tial... i tend to agree with you about the genuine stuff but apparently even genuine Tials dont have soft hard setting which i think is the poroblem, otherwise i would have bought one.

But yes that was my worry about them hacking my spring as i dont want to do any damage...

Do you know if i can get another spring that will fit that will have correct tension?

Cheers mate

no you don't.

You'll have to weld to get the TIAL one on there, so what's the difference to just welding to put a GTR one on there?

Will cost you around $50 IMO to have it welded + stock GTR BOV (~$70).

Problem solved, and the GTR BOV will hold 370rwkw in single form.

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated. Rb25det s1 walbro255 fuel pump nismo fpr holset hx35 turbo fmic 3" exhaust freddy intake manifold q45tb q45 maf   Re: s1 RB25det flooding at start up Fri Apr 12, 2013 5:07 am No, I didn't. I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Strange issue RB25DET wont start

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.
