I have this wastegate. Now how do I connect my boost controller to it?
No instructions came with it and I am lost.
thanks,
david

p.s. a pic would be great.

According to AEM's instructions...They show a line coming off the turbo and tee'd to the side of the wastegate and to the solenoid. The other end of the solenoid goes to the top of the wastegate.
Do I have to drill and tap my turbo?
Or can I feed vacuum off the intake manifold?
thanks,
david

it depends on your boost controller how it gets hooked up

what kind of boost controller are you using

I'm using the AEM tru boost controller.

you can block inline, creating restriction, causing boost to rise

or with a 2 port wastegate you can add pressure to the top of the gate forcing down creating more boost also.

Denmah,

I ordered a X02 Racing 60mm WG from VS racing for a side project. When you have used these in the past did they come with a very stiff spring in them? On my JGS gates I can hold them in my hand and push the valve with my thumb pretty easy ... I can't move the X02 one at all. Also do you modify the WG in any way before using?

thanks.

i just make sure that valve guide is low enough for the valve to seat against its seat tight, sometimes not often, the valve would have a gap, when you clamp both sides together...

so i would put a socket on the valve guide and hammer it down so the valve face would seal up nice..

but like i said rarely would that happen on the 50 dollar gates lol

make sure the stem has no burr's on it,

also the springs are usually super tight, usually comes with like 4 springs, 2 of wich are isntalled in the gate usually.

there is usually 2 larger springs and 2 small short ones

the largest spring, super weak you can collapse by hand usually 3psi ish

the next one 6ish?

both together 10-12

depends on backpressure and placement but thats how it goes

So where do I pickup the vacuum for the solenoid?
On the turbo as AEM shows in their instructions?
Or anywhere on the intake manifold?

any boost source, intake, turbo compressor, intercooler, piping, anything

That's the info I was looking for.
Thank you very much.

Ok, thank you for the info. Mine did not come with any springs (just the Gate) so I'm guessing maybe it has two installed. I'll take it apart so I can see whats in there and check things out.

What size injector are you using for the methanol kit?

3 things I didn't see anyone really touch on when talking budget builds. For reference the cam in looking at is 228/228, .571/.571, 112LSA. I probably won't spin it higher than 6500rpm if not less.

-stock timing chain
-stock pushrods
-stock needle bearings (trunion upgrade?)

I'm building a backup budget 2006 lq4 (might swap into a different car) and piecing together things to keep the overall price down. These are the three things I'm on the fence about. Looking for 700whp through an auto

I went with upgrades to all of the above on mine.

Following up on the Stock 4L80e Torque Converter...

Denmah... I know you've had pretty good success with running the CirdleD converters, but I was wondering... have you had any issues with reliability in running the stock converter? I realize that there are benefits to running an aftermarket one (great points below), but for a budget builder who already has a 4L80e with stock TC, have there been any issues running it? Say up to 650 rwhp... ???

Thanks all!

Did i miss the fuel filter portion? If so who has some good in-expensive options? im running a cell and dual 8's

Bumpity?

(Or anyone else had experience running the stock 4L80E converter in the 650-700 rwhp range? ) Thnx!

the stock converter handles power no problem it just has no stall speed

also for valvetrain i use stock rockers, stock timing chain, with all the mileage, stock push rods, you name it

the only thing i swap out are the valvesprings
