Looking for a bit of advice, as the topic says, our track car is an s13 with an s15 front running a built rb26dett with new garrett -7 turbos. It will be going in for a tune to get the best out of the new turbos and E85 in a week or so. Question is... I haven't got any heat shields on the manifolds, turbos or dump pipes. Is this going to be an issue? There are no wires or rubber hoses as all non essentials have been taken off.

Not an "issue" per say, but there's plenty of benefit to keep the shields in place when considering under bonnet temps.

You could leave them off and go an R34 GT-R style bonnet duct.

So long as everything is clear of the area you'll be fine. I don't run heat shields on my turbo/manifold (only a CA S13 though) and I have no issues with water/oil temps.

See how you go during tuning, if there's an issue go from there.

The heat shields certainly help with keeping heat in places and out of others... In a tight S Chassis bay, it's even more important you would think.

Be interesting to see another result of -7s on E85, it seems so far that those turbos just don't give the gains that larger ones (mid range and top end) do when going to E85. Be sure to post up in Forced Induction for people to have a look-see :)

      Apologies, while id like to put the MAF as close to the TB and relocate the recirc, this may be too much work. Will most likely end up just putting it on the original AFM spot ( onto/next to the airbox ).  Was going through nistune, found a pretty nifty doc on this. Nistune MAF Notes. Also, i was looking through the bay, and there seems to be a tube/line connected from the A/C to the intercooler piping ( Between the smic and the recirc), what does this do as the crossover fmic piping doesnt have any connection? plumbing? not sure what you call it but the nipple thing ahah.  Also, been reading up more about crossover fmic in regards to the legality of having the hole drilled for the piping, this would most likely need to be engineered right?

      My advice is if you need a big build done do it in Japan. The yen rate is so favorable and there are shops that can be genuinely trusted and not micromanaged/carefully monitored every step of the way. Garage Yoshida is obviously my preferred option but they're so busy these days and all interaction with new customers has to be mediated through BBL/Toprank now.

      I haven't....but a poorly made one would terrify me. Surely a good second hand one is the go, as they don't work hard and no-one wants to keep one after they are finished with it A big consideration would be the weight of the shell you are putting on it....is it a fully dressed chassis or just the body

      Not stock. All remade. Mostly looks stock because the pipes run to and from the standard holes in the inner guard to get to the return flow FMIC. I'm not sure which question you're trying to ask, because it seems like "stock position" vs "stock position".

      Hey, it's a GT-R, it's just as significant a moment as mine😁 It's not ideal when things are uncertain; I'm the type of person that always has a set plan for things in life so being unsure of this plan puts me in a weird place mentally.
