How much boost pressure? Looks like around 1bar from the figure. The cas holding you back? And what exhaust manifold?

Just trying to gauge if one of these is a compariable replacement to the trust item.

20psi with the standard manifold. Yeah the car stopped making power in the top end , the CAS is possibly causing it. Also hoping for abit more out of it with a decent front mount

Cheers

That is a lot of boost. You should be Comfortably making 260-270 at those levels. Did Trent check the signal from the cas at high revs or it's more of a suspicion?

Sounds more to me like a restriction somewhere. Roy mentioned the 20 responds very well to headers earlier in the thread iirc. Time for the old power of deduction me thinks.

Just a suspicion mate,

The exhaust can be ruled out I think as it is 3inch straight through with no cat and 1 muffler. Any other ideas would be great, the car is off the road at the moment and I have time to play around with it so any suggestions I will take on board and sus out.

Would be great to crack 260-270 before I venture down the e85 path

Cheers - Trent

A load of the cheap intercoolers work perfectly fine. If you can borrow someones multimeter that has an RTD and slip it in under the solicon join before the throttle body and just see what the temperature is doing between dyno pulls...ditto if you can get some cheap mechanical boost gauges and measure out of the turbo and post intercooler.

Not sure if it's relivent but I changed the spark plugs the other day and noticed that the inside of one of the clips on the coil pack loom is non existent and a prong on the coil pack was bent possibly causing a shitty connection? ( got a replacement clip ready to be soldered in just haven't hot around to it yet)

Sorry for the noob question but what's the difference in measuring the boost out of the turbo compared to the plenum where my current boost gauge is running off?

I got a td0518g on my car on eflex and 20psi I made 253rwkw only thing holding me back from more boost is my injectors Sr20

I still took it to wsid yesterday to see what I can run best I could do was a

12.5 @121.7mph 60ft 2.3 hopefully I'll be back in a few weeks to try to crack a 11s these are awesome turbos for the price

122mph with 253rwkw! Jesus, car must weigh less than a paperclip :thumbsup:

Either the car Is super light i doubt it as its full trim 180sx and my daily drove it straight there from work as is or the dyno must read low

I thought that cause when I made 231rwkw it was running 118mph trap speeds still did a 12.5 and alot of Silvia's had 250-60rwkw to get that trap speeds

I would be looking at coil packs / coil loom if you are getting actual spark break down. The CAS are usually all or nothing and Trent would have mentioned the timing being funny if the CAS was playing up. The curve looks ok, just on the low side.

Unless the timing has been pulled back to keep it safe whilst you sort out missfire / timing issues? That would make a LOT more sense based on the curve.

The only info that I remember being told is that the CAS may be an issue and that the front mount might be a restriction, he also mentioned that my timing belt might be out because he expected the car to be abit more responsive. I recently replaced my water pump and upon doing so checked the belt and it hasn't jumped any teeth.

I'm not to sure if the timing has been pulled back or not. As for missfiring issues the only time I have heard a miss is at really low rpm. I've wrapped my coil packs/ changed plugs and in the process of fixing the loom so I'll see if that has made a difference.

Thanks for the feedback guys

Which wastegates are the majority of u guys running with these kandos- tial mvr 44mm/ turbosmart compgate 40mm?? Anyone running 38mm gates with success?? Talking about Boost range 18-22psi.

I'm running a turbosmart comp gate40

Dori, if we don't see results tomorrow we will go and have a face to face with your tuner.. Seriously man, give it to DVS JEZ, he will sort you out in no time, a lot of those large workshops are a waste of time IMHO..except for Yavuz who is a gun tuner.

^ and you have first hand experience with them all? lol

in all seriousness, large shops (regardless of good or bad) are always busy with lots of work. a couple of days is hardly a poor effort.

    • It's the adhesive holding the ceramic wheel to the shaft the fails on 90% of them.
    • Foreign debris, physical shock, boost leak, could be anything honestly. The danger in taking all the timing out of a tune/hitting the R&R corner is that even if the engine doesn't detonate your turbo is taking a lot of abuse from high EGT. Also, even if nothing goes wrong it is a journal bearing that is spinning at 100k RPM on boost. Eventually it goes through enough cold start/pressure cycles to wear it out.
    • I kinda accidentally saw this, and was interested, but It actually seems to replaces the whole center computer, using the existing screen and buttons. AND it may only be for a G37 and not compatible with a Japanese 370. So its not for me, but someone else may be interested to look into it. Its about $680USD. If I am understanding it right, it basically replaces/installs and android pc that integrates with the existing screen. But I could be wrong. https://gromaudio.com/vline/ The video I first saw was the following, with very little and unclear details.     Even if your not interested in the system, the video on their site was pretty comforting in showing how simple the whole centre comes out
    • hfygrte52 what side you looking for? Do you care what color car it's off? Found a white LH side on here: https://skylinespares.com.au/product/nissan-skyline-r33-coupe-rear-tail-light/   Aussie parts place but will ship to USA. Maybe get it before there's a tarrif on 25yo shit box parts
    • I’m with Shannon’s for all 5 of our cars. Agreed values seem fair, premium price is okay. ($210 ish a month, all comprehensive).  Have claimed once with them for a not at fault claim with another car where my car had no damage. Was one call after the incident and an email after. Deemed not at fault so premium didn’t go up either.    I have called up and spoken with people who are not familiar with certain cars and didn’t agree with me on value or let their personal vehicle preferences effect the call. But called back later and got someone else who was more agreeable.
