woohoo cars developed a missfire which rapidly became undrivable when warmed up.
possibly head gasket/ fluid in cylinder type thing...possible coilpacks...possible ignitor.... possibly just the wrong temp air in that part of town...ok now im just hoping for the best.

ok good news. heads fine. coolant looked a bit... off colour so well flush  it and keep an eye on it. you never know their might be an underlying problem but for now she's running sweet again.

im over spitfires and ignitors so I'm now running R35 packs. much simpler. problem solved. cheap outcome is a good outcome.

 

now back to working out how much to spend on bushes and coilovers.

My vote MCAs.
I went over the top, put MCA reds in my 33, Josh at MCA tuned the valving for me after a chat about what i wanted.
Took all of the sketchness out of bumps on hills roads like up to Lobethal that my old Tiens had. Feels stable in the corners but doesn't jar the spine on Port Road. I'm sure their street options would be just as good, but perhaps give them a call to chat.
They're also perfect for sitting in the garage with engine out too, sigh.

odd question, my collant is overflowing normally into the overflow tank when the engin is shut off but its not drawing back in when cooling.
imusing a 1.3kg cap which is the highpreasure cap, is this likley to cause an issue for basic driving? shoudl i revert to the nomral 88kpa cap?

Awesome build!

Sounds like a lifted head or gasket not sealing somehow. To exceed that cap pressure you'd have to really be running that motor hot and I don't suspect you are. A lifted head or bad head gasket seal will push coolant like that at operating temp and pressurize the system. When the motor cools the pressure is still there because it wasn't caused from heat in the first place. Are your rad hoses rock hard after you romp on the car a bit?

    • @Kapr Haha yeah thats the one. I missed that you had a built up engine, I wouldn't want to run it on there either then. It was good in my situation just to replace the original turbo on a stock engine. @MBS206Yep definitely not a replacement for anything name brand
    • You are selling this? I have never bought something from marketplace...i dont know if i trust that enough. And the price is little bit "too" good...

    • It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.
    • By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.
