Turbo BS Thread

Spark plugs look good. How malleable are the seals around spark plug tubes?

 

The seals were really bad cracked and hardened. I’ll finish up putting the new ones in today do a test drive and everyone know if this resolves the issues

 

Both have variety but anything available in the aftermarket tends to be larger than I need. At 11.9:1 the compression ratio is dumb high, so extra fuelling, water/meth, and a properly sized turbo (efficient at peak power) are my best chances to make it live. I can't drop compression on this as no pistons are available short of custom ones so I'm limiting myself to the 7psi/250hp level for longevity. The smallest Garrett units might work, but I'm looking for other options before I settle on any particular turbo.

 

just put like 4 head gaskets on it, should be good to go

 

for real tho, would something like this work? https://www.full-race.com/store/borg-warner-efr/turbos-efr-series/borgwarner-efr-6258-turbo/ a little price for a low horsepower build I guess but it says that for single turbo applications it should be good for 260-440 hp

 

A bit big, but the efficiency island is weighted towards high pressure. Plus it's physically huge. Those would be perfect for a 'Busa build though.

 

You'd probably like a bw ko3 from a vw

Those have been where I started the search because I know they'll spool well with my motor. My ex had a Beetle Turbo S making 270whp/320wtq on one, so I know there's room to grow with them too. The only fear I have is that wastegate spring being both stiff and inaccessible. One overboost and goodbye engine.

 

This is a method, if thicker headgaskets are available. A little math would give you the clues to how far you could drop the compression.

 

Well autozone didnt have the right o-rings yesterday so i used cyanoacrylate to make mine work hopefully

Dont worry about that blue rtv, i used to be a little dumber than i am now, but didnt we all?

 

Just lower the tension on the arm and go up from there. Probably have to pull the turbo to adjust it unless you make the wastegate face out.

 

could you run and external wastegate as like a safety net, that either had a just higher psi or the same, or I guess even lower and forego the internal wg all together?

 

This is an option and kinda where I plan to go if an aftermarket option isn't feasible.

I hadn't considered running an external if there's an internal one available. I prefer an oem internal for reliability and packaging, but an external safety net is a good idea.

 

That's exactly what I was thinking, a head spacer will drop the compression

 

didn't get a reply to my question but i ordered anyways.


also ordered autometer 15411 single gauge pillar pod.

 

I'm looking around but not seeing a lot on them for my bike. Hopefully cometic has something thick for my bike

 

Nice! That looks pretty sweet. That a nice clean concept having both gauges combined into one

 

Nobody mind me...

saves money over buying seperate gauges too. cost was $430 canadian pesos
