Anybody using a Godspeed 38mm wastegate? Just wanted to see if people had or have a any problems with them.

Also, Godspeed intercoolers. Any comments?

Thanks

 

I am not a brand *****, but your wastegate is not the place to save money. Your engine thanks you in advance for purchasing quality.

 

don't do it

 

Thanks, didn't know that they are crapy quality. I'll stick with Tial 38mm then. For some reason I keep thinking that I'v seen the Godspeed intercoolers in many nice builds, so I thought the W/G might be good as well.

Guess not.

 

An intercooler is basically a radiator for air. If it fails, whats the worst thats going to happen? - you lose boost, thats it.

If your wastegate fails, you are going to overboost and unless you have an EMS that will cut fuel, bye bye engine.

I can't imagine why you'd want to switch from a top quality part like Tial to a Godspeed anyway.

 

I am not switching anything. I am assembling parts for a kit that I will be buildig myself, and this is a part of my research.

 

werent you doing a rear mount?

 

Don't cut corners on a wastegate. If you do, please make sure you have overboost protection in your ems.

 

Yes, initially that was the plan. Now am have thrown the APS style setup in the mix as well. So I would say that I am on the fence as far as what setup I am going to run.

Both require a scavaenge pump, so that's another $250 thrown in to the mix. I have sourced everything and am currently buying things one at a time. I already have an inline fuel pump, UTEC with map sensor, and 400cc APS injectors with harness.

The piping will cost me about $200 with turbo flanges, so I am on par with my $3000.00 estimate. That does not include a clutch and tuning.

I am still trying to figure out some other stuff as I am new to the Z world. Things like check valves/vents to prevent crankcase boost, and routing a catch can. I am also looking at some GT3582R turbos that have water cooled centre housing, not sure if it is necessary to have the cooling routed as I am not planing to run high psi. I'll have to contact Garret on that because I have read some contradicting iformation here.

 

I am not sure if UTEC has overboost protection, I am reading up on all that as well.

 

Haltech does! It also has PID-tunable closed loop boost control. EMS is another place I wouldn't cut corners if you absolutely don't have to... gl!

 

If you overboost on a UTEC it will cut fuel. You can set the overboost fuel cut at whatever you want. So yes, UTEC does have overboost protection. And it works quite well, ask me how I know
