whatsup celicatech, im just curious to know which wg is reccomended and why. i have the option of getting a tial 38mm ewg ir an hks 40mm wastegate. i need a minimum od 38mm so the 40mmhks is fine. does it matter which brand i go with? just curious what some peoples inputs were. ie: the tial might fit under the hood better or that the hks lasts longer. stuff like that. let me know, thanks!

also, this is for the st165 with the 185/205 swap. (185 block 205 top end.)

My personal preference would be TiAL. I say this because they are a US based company, and service / support will be far easier to get from them vs. HKS. They have been proven to be high quality as well. The new Tial's are a bit slimmer too if being compact is important to you. Also, they have an option now for water cooling as well for a little extra reliability (however, you certainly do not need to use this feature).

The smaller diameter you can get away with the better. Bigger is not better.

hmm, really? because theres also the option of a 35mm bnib tial wg. it was part of a project car the person bought and hes selling it for 140 plus shipping or best offer. but why is it the smaller the better?

It's like having an overly large throttle body, smaller movement makes for larger opening with a larger diameter. Makes the valve less responsive and spikes easier. Smaller is easier to control.

hmm, so what youre saying is that smaller is easier to control? and youre reccomending going with the 35mm? i never thought about it that way, but what youre saying makes perfect sense.

btw- what part of cali do you live in? im here in the bay area.

Yeah, you can't link pictures from your gmail. Upload them to the ctech gallery or photobucket or something.

I would go with at least a 38mm TiAL. I don't think you would need to step up to the 44mm yet.

tial
hks has a very old design and they are stupid huge.
i wouldn't use a classic 38 unless you have to. look at the new mvs. much smaller and easier to work with
