Thread: Starting to look into boosting my VE and have a few questions.

I think since i have decided im ready to conclude my build, i have decided that i will no longer build an NA car and finish my car with going VE-T. Not sure what i will be doing with my ITB's but i will keep them for now. With that said, if anyone can chime in, i have a few questions about boosting my VE. My goals are simple. My car is a STREET CAR, so i don't need super high horsepower, so my hp goals are about 320-380/400whp tops with stock pistons. I don't think i want to go any bigger than a T28 size Turbo so i think the VET ex. manifold should be more than enough for my HP goals.
1. If i got a GT2871R (used) now and later upgraded to a GTX2860R (new), are these turbos similar that i wouldn't need to change my intercooler piping/configuration?
2. Is the stock compression of both the VE(10.3:1) and 20V (11.0:1) going to be OK at 400whp or am i being too enthusiastic? I am even ok with just 350whp if my compression is too high. I will be using a Series 2 AEM ecu.
3. I have noticed(never looked into turbo before) that the intercooler piping ranges from 2"-2.5" on similar set ups. I am assuming going 3" intercooler piping isn't needed and 2-2.5" piping will be fine?

Thanx for everyone's time.

You could run a t28 turbo lots of us do. You main problem is crap cali gas. The aem is a good choice for tuning. I like the stock vet manifold and it will allow you to run the largest of the t2 turbos(3071r, 3076r 56.5 turbine). 300-350whp should not be a problem with the right tuning and turbo.

Not sure the GTX2860R is an "upgrade" from the GT2871R as far as power potential is concerned. A quick call to Garrett should sort out your question about both of their fitment being identical.

2.5" charge pipes will be plenty.

Stock compression and stock rods are your limiting factor, but you should be okay up to around 400 WHP.

Good choice on the VET manifold and AEM Series 2.

Awesome guys! Thankyou for the quick response. Ill keep everyone updated to those who wanna know.
