You should go on E30tech for more advise.

But since Im here tonight....

Budget= dual OE Bosch bypass valves and used Tial 40mm. Id avoid eBay because Ive used their wastegates before, it works but under prolong conditions of use (ie extreme heat) it fails. Twice now.

A failing WG is MUCH more costly then the unit itself will ever be. Keep that in mind for everything you purchase.

Goodluck!

tech and r3v arent options.

ya, i just decided to go with Tial stuff. ill make room in my budget, because it will save money in the long run. im gonna get a Tial 50mm BOV and a Tial 38mm wastegate. it'll also save me from having to upgrade to the tial stuff later. might have to do dual 38mm WG's if i decide to do split pulse. but im still on the fence about that.

I would not run the Tial BOVs...they suck in my opinion.

Why no R3v or e30T?

Sucks you got banned. Lost valuable sources of great info, both for 24v and boost lol.

No what Yoshi recommends sucks. You have to balance vacuum force with boost force which is an option you should not have to make.

Get a by-pass valve. HKS, Synapes, OE Bosch, Forge, or the billet versions of the OE Bosch floating around under several different names.

Cheapest option is run dual OE plastic Bosch ones. Those can be had for free sometimes.

Dont listen to Yoshi too much...look at his history (I kid... :lol: )

lol my bov and WGs work. *shrugs* I want to upgrade eventually but ebay WGs seem to be hit or miss. I have overboost protection on my megasquirt so its ok if my WG dies mid drive. I wouldn't skimp out on a WG unless you have some kind of protection. BOVs are... eh. If they fail, you probably won't kill stuff immediately.

Over boost protection does nothing to ruin your day.
When you pay a few hundred dollars for a weekend of track time to only have a WG fail, it sucks. Or gain DNFs and loose out.
It also does not prevent in turbo over speed.


But the main question is...why do even want your shit to fail in the first place? Having a safety net should not mean you have to fall.

Cuz im poor? Get the setup working now, upgrade as I go! The gamble is on what can wait and be cheap now and what must be good quality now. Yes it's true I could spend a bit more on the WG but then the same could be said for a lot of things. My $3k build could easily go up to $5-6k. While I'd love to do that, I don't have the cash for it nor do I want the CC debt.

I already recommended you what I think is appropriate for a "budget" build.

Used Tial WG (40mm+)
2x OE Bosch bypass valves

Shopping around is key. One time eBay surf doesnt cut it. Forums usually have good deals also.

Think about it. The less boost your turbo is kicking out, the more the WG has to bypass away from the turbo. I'm running a 38mm WG and I think I'm getting some boost creep.

this much is true. but i plan on running a dual port manifold to utelize the twin scroll. i probably should have mentioned that from the get go. id have 2 x 38mm wastegates. which i think is enough.
