MattyZ Posted June 4, 2010 Report Share Posted June 4, 2010 Hey all just curious I'm looking at putting a 3sge into my ta22 and adding a turbo my q is has anyone used a 3sge with a large turbo, i know lag will be an issue but will the 3sge still have reasonable pick up till the turbo spools up or should i just get a turbo that spools up straight away, I'm looking around the 225 - 200rwkw mark so if i have a turbo that only spools up later it will be a bit better to handle with every day conditions right?. and i don't want to be running crazy amounts of boost too as it will be a daily. any ideas, suggestions etc will be awesome matt Quote Link to comment Share on other sites More sharing options...
LowVp Posted June 4, 2010 Report Share Posted June 4, 2010 if your daily driving it you want a smaller turbo so lag is minimum and won't take long to get to max boost, if you were going for all out power then sure go a for a bigger turbo but if you to daily drive it you would find that to make any sort of power you would end up reving the guts out of it continually. i'd use something just a fraction larger then a stock 3sgte Quote Link to comment Share on other sites More sharing options...

Toy-Yoda[RL] Posted June 5, 2010 Report Share Posted June 5, 2010 If you wanna talk "reliability" and "daily", you're best to leave the 3SGE as a 3SGE as it was intended to be as opposed to slapping a turbo onto it...... For a weekend car, I'd be all for chucking a 3SGTE in and boosting the nuts off it and seeing where it ended, just make sure you have roadside assist :abuse: Quote Link to comment Share on other sites More sharing options...
xmoht Posted June 5, 2010 Report Share Posted June 5, 2010 not sayin ill be dragin every single light thats just stupid Not dragging every single light, does that imply you'll just be dragging on the occasional light? Quote Link to comment Share on other sites More sharing options...
MattyZ Posted June 6, 2010 Author Report Share Posted June 6, 2010 Not dragging every single light, does that imply you'll just be dragging on the occasional light? oh shit no, not draging i don't drive a VL commonwhore, but everyone has a spirited take off once in a while lol.

ke70dave Posted June 7, 2010 Report Share Posted June 7, 2010 you confuse me!! you want driveability for a road car = appropriately sized turbo (note i did not use the word "big" or "small") you need the turbo to be small enough to make some boost low down in the rev range, and large enough so that it can hold your chosen amount of pressure all the way to redline. there are lots of different factors in turbo choice, that i don't even completely understand, rear housings, front housings, wheel size etc. i don't see how having a turbo that doesnt spin up untill 5000rpm is going to make daily driving easier, or "save your chassis". i think you might need to re-evaluate your plan, first you say you want a magical power figure? but then you don't want to damage your chassis with a powerfull turbo??? also you say you don't want to run high boost, yet you want boost to come on at high revs? your poor waste gate is going to be working overtime to allow that to happen. i say forget the power figure, pick an amount of boost you want, and where in the rev range you want it. then scour through compressor maps and see what suits your requirement. or like others have stated, put in a stocko 3sgte and see how you like it. then mod the engine as required.

Karllos Posted June 7, 2010 Report Share Posted June 7, 2010 To add to that you say you don't want to stress your engine, by runnning a larger turbo that takes longer to spool, it is going to put more stress on your engine by the process of continually putting it under load because of the lack of power being made to get up to speed. Also, pick and choose between absolute power, from what you have said so far my understanding is you want something that can make reasonable power but still spool and be easy to drive... In that case, see what size turbo's relate to the stock one and see what is somewhat of a good increase in size, speak to turbo specialists and people who have experimented. One other question is are you going to be building this engine? because if your not then its not worth going for a larger turbo due to the fact that the 3sge wont be able to hold the boost pressure over say 5-6psi So in other words, id be going with a 3SGTE from factory and going from there, can always upgrade and is easier to upgrade parts than to down grade :) Karl.
