So after i changed my turbo to a little bigger, i have noticed that my enginebay gets really warm on drive, i mean really hot. So what to do with it? I do not have the original heatshield on manifold, should i get one? How about wrapping the dp? Manifold is too extreme to wrap, becouse its shape, i think? Watergauge stays ALWAYS on the right spot when the motor is warmed on drive, and it cools down very slow too

What stage tune are you running? Are you running a full 3" exhaust? What injectors do you have? I am thinking your EGTs could be too high. Have you removed the rubber seal at the back of the hood? This will let the air flow over the engine more.

A heatsheild is fitted for a reason;) - I think you will find your problem is solved once you fit it.

Earlier cars had no heat shield. I ran that exact same turbo at Stage 5 JZW without excessive underhood heat and no heat shield. And I had a heavy duty underhood liner in place. But I had 50 lb. injectors and 3" stainless from the turbo back.

Exhaust is full 3", custom home made :cool:
It doesnt leak, i have tested. At the moment, i have stock injectors, stage 3 tune. Waiting to get money for injectors and bosch 044, then get a jzw stage 5 ethanol tune.

I havent removed any rubbers, i could try that.

Well, i dont know abou the egts, dont have gauge for that

Yea, but i dont want to remove manifold for wrapping it. Well, i think i could do it manifold on car, would wrap the dp too. Think that would do the trick

Keeping the heat in the exhaust manifold means you get more power to drive the turbo. Wrapping can be done with it in situ with thin wrap - fiddly but I've done it. A heatshield reduces the cooling effect on the manifold of air blowing through the radiator.

Kenneth, how much wrap did the manifold take? Im just wondering how much i should order it to the mani and dp. Theres some cheap wrap on ebay, its 4,8 meters long, would that be enough for both?

Okay, it helped, and i also removed to rubber seal, i think that will also help a little bit. Damn that wrap stinks bad, well it suppose to stop it in few days. Fiberglas itching in nice thing by the way ;ol;
