twins can only do so much, i saw someone already with a gt35r garret on their engine. its worth doing if your into that type of stuff.

i remember someone saying if they had to do it again they would of just swap in a evo engine and work form there due to the lack of parts for these engines.

I heard that td04 would be a great upgrade because of clearance issues, is there any one with info on this upgrade

Going single gt35r turbo is nice but you may be sacrificing some drivability. Twin td04's are the usual upgrade for the engine with 600cc+ injectors.

Td04s from the subaru or the 3000gt are swapped in. I'm not too sure of a sure place to find them. The main challenge for me is the space in my bay. If you looking for high output then single away but I like the quick response of the twins so twin td04 13g I think they are would be my choice.

Work with the stock twins and focus on traction, cooling and holding boost. Is it for a galant awd with manual or tip?

Well this engine loves manual transmission. Get it in a lightweight car like a fto and you'll be able to run with the following stock for stock: sr, rb25det (rb20's not worth mentioning), rotary, 4gxx, jz's, vg30dett you know all those "monsters". In the galant seeing it's a heavier car it'll be a lil more of a challenge. Oh I forgot stock legacy gt's.

Im going the route of the td04s although i already have a big single turbo, i also have 640 cc injectors and a greddy ultimate to install may put in forged pistons later on because i want to be pushing at least 500 to the wheels any other suggestions

Sell the piggyback get a plastic ecu if you have a turbo sitting around put the bugger in. Forging it not cheap but I don't know your pocket like yourself. Is awd or fwd?

I saw a pair or new td04s for the 3000 gt vr4 on sale for $840 US so may order those or may get a cheaper local set.

forget bout the mines tune.....its great for a stock engine running more boost.
but for a modified engine its more of a base tune which needs to be worked on by a good tuner.
Plus it needs to be expanded to fit the bigger higher resolution maps in the new KSMods ecu firmware.

3000GT turbos are to small.....get 2 subaru turbos they bolt straight on with slight mods an are big enough to give higher exhaust flows to match the new higher intake CFM

xtech can all the sensors be used back with this tune? just the values will need to be changed right?
