Just installed my new turbo and it's getting HOT! HELP!

[2.2lsr20dets14]

Hey car knowledgable people. I just installed my new turbo setup, nothing big just a little upgrade till I finish other projects. I have an S13 sr20det and I just put the t28 bb turbo on with new headers, turbo elbow and ss lines. I used an oil restrictor and also installed the HKS actuator. Got it all put together, refilled the coolant and it started right up. But once it ran for maybe a minute I noticed it smoking a little, then that went away. After another minute or so I notice the headers and the area around the turbo getting extremely HOT! I mean blazin hot and the car hadn't even gotten warm yet, so I turned it off. It wasn't smoking any more it was just really hot. So is this normal with tubular heads or a new turbo or is there a problem. Please pm me you thoughts. I need any help I can get.

turbos get very hot, what was it doing?

[2.2lsr20dets14]

It was running fine it just got so hot I could hardly put my hands above it. I'm just worried something might not be operating right.

[tunerman_sam]

thats normal

Equal length runners will actually create more heat. Your car's not going to die turbos can reach up to 1200 degree's celcius (not that t28's can but just saying) you can always run an exhaust gas temp sensor, not sure what an "IDEAL" reading would be.

You could always switch back to the oem manifold which takes heat a lot better than what sounds like a shitty show car manifold since you didn't mention any specific names.

I don't even know why people install shitty tubular manifolds.

A log type performs better during a majority of this boards use. Unless you are pumping major power, it is a worthless, 'upgrade'.

Ceramic coat / honed x extruded stock. DONE

The smoking was from all the oils from your hands getting burned off and possibly the new gasket you put on (depending on what kind it was)

[redline racer510]

Best thing to do is let your car run for 10 min rev it to 3K rpm for 20 seconds and then touch the turbo and see if its still hot. LOL JP turbo's and the "header" can get incredibly hot, I mean hot enough to give you a pretty bad burn(2nd or even 3rd degree if your dumb enough) unless the heat is causing your engine to not run properly I wouldn't worry bout it. good luck

this seems like it would cause lots of damage, no?

i mean i know turbo's get hot as fuck, but this seems TOO hot

[2.2lsr20dets14]

Thanks for all the imput on this. I'm probably just getting paranoid. I actually had a local shop make me a custom set of tubular headers so thats why theres no brand name. Just curious but is it better to wrap your headers if you can or just leave it unwrapped?

[MrJdmEh2]

Good and bad idea helps keep in the heat but it will make your manifold more prone to cracking. A lot of people use turbo blankets those are pretty good and dont damage the turbo.

Wrap it, also install a shield between the BMC (brake master) and the turbo or you will melt your brakes thingy.

google : S13 bbrake master cylinder heat shield and you will get it, other wise take and old Plate and bend it to shape and you are done

[GroundPerformance]

SS headers gets really hot and crack easily.. Considering you only did a T28 upgrade IMO you should have just stick with the stock manifold and heatshield. GL!

[2.2lsr20dets14]

Thanks for the advice on wrapping. I was kinda thinking the same thing on it keeping the heat in, didn't know it could cause cracking.

I actually made one of those head sheilds for my bmc and put some of that heat tape on it. Seems to work real well.

[DinoMan]

Yeah turbos get hot and the gaskets need to set in. if your top mount a blanket would be a pretty good investment. with a bottom mount i could be wrong but it seems it would be harder to put it on. Wrapping the mani could keep your bay cooler but makes your mani even hotter underneath the wrap.

[ZilviaKid]

they dont fucking crack because of wrapping them and im sick of people saying that. a shit manifold will crack regardless.

i bet the people who said they crack have never wrapped a manifold in their life LOL

[MrJdmEh2]

You obviously do not know all your facts! Yes a crap manifold will crack. But like i stated before wrapping will make a manifold more prone to cracking. Why? Lets use common sense (yes i know common sense is not to common) wrapping a manifold is gonna hold the heat in making it hotter because the heat is not escaping... Wat happens to metal when it gets super hot ???? Yes it gets weaker which is what is making a manifold prone to cracking... Remember unlike na cars the exhaust manifold is holding up a heavy turbo. Weak metal + weight of a turbo... U do the math.. This is why companies like full race reccomend u DONT wrap the manifolds but i bet u neva bought a full race or any REAL quality manifold..

Did anyone read this?

[chiboy002]

Did anyone read this?
people tend to disregard valuable information when theyve already convinced themselves that it is wrong.

OP prolly thinks log manifolds are eyesores and therefore is willing to spend more coin on something not worth it

Agreed but the OP didnt ask what kind of manifold is better either... He obviously doesnt know too much about manifolds/turbos and is just asking a question.

[jvega]

i had my manifold wrapped, then it cracked. i took it off and it hasn't cracked.
idk what brand it is, it came with the motor from japan..
but is it getting red hot at idle or what?

[2.2lsr20dets14]

no its doesn't get red hot at idle, but its gets so hot you could probably stick the frying pan over it and cook. I think i'm not going to wrap and just see how hot it gets in the engine bay area. But if anyone has any ideas as to how to maintain the temp as best as possible please send them my way. My main concern was that the turbo was getting oil and coolant run through it properly and it seems to be working good just didn't know that those types of headers would get that hot.

[EsChassisLove]

Install an egt. If your running stoich you shouldn't see more than 850*F at idle. Which is fucking hot. Under WOT the highest temp I have seen is 1350*F. Under normal cruising @2500-3000rpm its around 1100*

EGT gauges are awesome. Invest. Good luck.

Edit- I don't think they get red hot until 1500+*F You would probably be able to feel that heat in your floor board from your Downpipe lol
