Boost controlling

[TRE]

well once it is set I don't plan on changing it.... that is what i was trying to say... is there certin contorlers that have better responce or lack boost spikes or will a simple boost controler do that for me no problem?

What are the advantages of the electronic boost controlers?

If you dont plan on ever changing boost whatsoever, just get an 18 psi spring for the WG.

[TRE]

can't they dont make one, I have a turbonetics evolution wastegate

[integra_gsr98]

What is the flange like? Maybe you will be better suited w/ a TiAL wastegate. I have never been a fan of turbonetics wastegates.

[TRE]

I want a tial wastegate, but I already have the turbonetics one, ... is there anything wrong with the turbonetics one? Any info would be great... I am having nick weld a flange on there anyways for the turbo I'm sure it wouldnt be too hard to reweld a flange on there for a tial wastegate... just more money for no reason ya know... but ya give me some info

[TRE]

just trying to use what i have I guess ya know...

how accurate are those tial wastegate springs? if i get one that is 17-18psi is it going to be right on the nuts? one more thing, is there going to be wastegate creep without a boost controller?

[integra_gsr98]

That's a 35/38mm flange. Boost control w/ just a WG spring, especially a tial WG, is ROCK STEADY.

[TRE]

hum... size wise is there a difference? like will I have a clearance issue with the tial one? cuz this is premade and stuff. Rock steady huh, sounds like the ticket, it will be an extra 150 from what I can tell. so... could maybe do it.

[integra_gsr98]

Tial 38mm should only be 250 some dollars if I remember right.
Check w/ straight line for an actual price.

[TRE]

well i figure i could sell the other wastegate on ebay for about 75-100 and i was going to spend like 50 on a boost controller... and the tial is about 275 with the spring I need. so about 100-150 extra dollars see my thinking lol

[TRE]

Size Difference Anyone?

[PSiedTSi]

bigger=less chance of boost creep and most likely better control...

[TRE]

I would like to know for fit, not for boost control, I know both will be fine for flow cuz I'll be pushin 300hp at the max, I think my 1.3L block can only handle 340 before it is about to break.

[integra_gsr98]

Size wise the tial's are usually smaller than the turbonetics wastegates actually.

[TRE]

sounds like a plan, they have a 17.4 psi spring so I think i will go with that, they also have a 18.84 psi spring.... My fuel is set for 18psi but then i am going to fine tune just a bit, witch spring should i go with?

[TRE]

One more thing what is this thing about wastegate creep or whatever it is called, do i need to worry about that? Worry about my wastegate not allowing my turbo to spool as fast or is that more for non external wastegated turbo set ups?

Go with the Tial 38mm with the 18.xx spring. What are you putting this on? You mentioned a 1.3l engine, you will not have to worry about creep with a 38mm gate at ~18psi. This would be a perfect setup for you.

[TRE]

better to go with higher boost than lower boost?
