Greetings everyone! New member here on the brink of putting a deposit down to order a Redline, and just had a few questions that I can't seem to find the answers to anywhere. 1. What size and brand of turbo is GM using for the Redline? 2. Does anyone have any info. on internal mods. that GM has performed on the Ecotec to withstand turbo boost? ie. Forged internals, etc. Finally, any figures on what stock boost is rated and this is redundant, but what the motor may be able to hold?

Thanks in advance for any info.

The redline uses a rather small turbo which is considerately maxed out. I'm not sure of the brand but I'm sure its gm made not a garret if that's what your thinking. The motor is actually similar to the evo. 4 cylinder alluminum block forged crank and rods. Open deck I believe. There is a diagram @ the top in the sticky I believe under gxp info. The car is running 20psi which is also like the evo. Still very high which is why I'm thinking the turbo is maxxed. I'm guessing the motor can handle a bit of power. I think stock turbo maybe 300rwhp tops. Don't forget the 260 is at the crank. I think w/ a new snail this motor is capable of 400rwhp. The limiting factors will be the trans and the direct injection fuel system and what they can handle. I can see you are interested in modding the car as am I. This won't be that mod friendly of a car just guessing that the aftermarket will take years to find it considering the buyers group is a bit older and more pure than us well @ least me. Hope that helps feel free to ask any questions u may have... James

That is quite an exception. That motor has far from stock internals and turbo. It is unfair for someone to ask what the modding potential of a car is and give them a 100000.00 dollar example. Within reasonable budget and modding my estimate still stands. Not to come off as a jerk or anything but I'm sure with the right money and resources anyone could make any motor 1000hp but I was thinking of real world applications.

hello.
I am trying to recall the model of the turbo. but last i read it was aMitsubishi turbo, essentially the same used on Saab V6
condors and crank are forged, blok has a oil sqirters for the pistons. So thumbs up. as I can see gm putting out a true turbo egine/block on the market. Thumbs up!!!
as far as discovering full potential of the engine....well modding bug bit me a while back but with the TQ curve as that engine i am betting it will be awesome fun to drive! Modding, well I would wait to see wht aftermarket got to offer in terms of fuel system, not like there is a huge market for direct injection injectors.... I wish GM would have a stage upgrade system. I would be looking at ECM tuning to begin with as faras strapping turbo....well if 20lbs at the smaller turbine still should be awesome throttle response
ilber...just my 2.0 cents

Also, the GXP Drift car uses a completely different transmission - 6 speed, not 5.
And a water to air rather than the standard air to air intercooler of the stock GXP.

Thanks for the info. guys! Sounds like GM did their homework. Oil squirters, forged crank/rods, etc. sounds promising. While I'm not looking to heavily mod the car, I would like to tweak it a bit. Any word on the intercooler? Front mount, side mount, sprayers?
