hey im in the process of parting up for my turbo build and i jus wanted to get sum suggestions for what size/model turbo would be best. i have a stock 2.2 and all im plannin to do is get a safe 8to10 pounds with stock internals, injectors, FMIC, BOV, wastegate...u know..the usual and not to mention turbo grind cams as well...any help is appreciated:twothumbs

8 to 10 pis with what kind of flow. A 16g does not flow the same amount of air at 8 psi as a GT47. I hate how people define power by PSI.

A good turbo for you would be GT2876r. Its a nice midframe turbo should be able to provide over 300 whp if wanted but can be more conservative used if desired.

i wouldnt wnt mre than 250whp since i plan to keep internals stock for the time being

t3 turbo

14b or a 16g get a turbo map what's the best

t3 garrett?

check out the forced induction threads/stickies. Theres pretty good explanations on picking turbo sizes. What do you want, a small, quick spooling turbo that'll peak fast, or a big, slower spooler?

Keep in mind though that for a fixed system, 8psi is 8psi as long as the temperature of the air is equal.


I agree that a GT28 would be probably about the size you will want.

The system is dynamic.

2871r

t 88..muahaha

yea probably a quick spooler thats fast-peaking up to about 10psi

t 88..muahaha

haha yea that sabout the size of my donut in the trunk..thnx n e way :lol:

2871r

nevr heard of that ill look it up thnx 4 the input

GT42R

My turbo.

Buy it from me...

wat turbo would that be?

t25 or 16g

you've never heard of a GT28 before? Thats one of the most popular 4 banger turbos out there. GT2860 and GT2871.

Its a good one. Whats your budget though? A newer borg-warner turbo would be very nice, though i imagine theyre a little on the pricey side. Also, I imagine a K03 or K04 would be a good one for low power levels and maintaining a quick spool (as the LNF demonstrates)

I have one of those in my closet! It's for a future M52 swapped E30 BMW build my good friend is doing. Hopefully we can get that monster to spool! I like 700-800whp in a gutted 2100 pound car. Tire smoke is fun! lol

Sorry, back to the thread.

t3/t4 60 trim garrett

thats too big, and over kill for a 2.2L.

Id say for streetable power in a FWD car. you dont need much more than 300-350hp

Thats why i said the GT2871r (56 trim)

in all seriousness tho 16g or BIG 16G. good for 350+whp.

The system is dynamic.

What I meant was that given the same volume in the intake tract/head/cylinder that 8psi of air is 8psi of air as long as we aren't talking about temperature. A bigger turbo isn't going to "fit" more air into the same psi in a fixed volume.

Unless I'm way off my rocker in which case help me out. lol

but bigger turbos are more efficient compressors, and the air charge will be significantly cooler, meaning a pretty different power number is possible with the same PSI.

Otherwise, yes, you're correct

good to know.. i was lookin into the turbo that comes in the garrett kit..its the gt2806rs i think?

^^ disco potato! yea, a gt2860.
its a good little guy, and will get you the power you wants

i have a GT2860rs right now in my Nissan. Right now my injectors are maxed out and im only making 270whp.


Since i want more power, im going with a GT2871 (56 trim) good to 400whp.

wat are its pros and cons? hows it spool?

its a larger turbo...slightly longer spool time with slightly more power

boost starts at 2k rpm, I have 13psi before 4k rpm. (2 liter, 8.5:1CR, 270whp)

For a engine with 9.5:1 or higher CR the spool time would be better and with the right tuning and supporting mods, you could hit 300hp

you could hit 300hp with a big 16g and have a quicker spool time. The thing is, the compression ratio is like 10:1:1 on the 2.2L or something like that. With the higher compression, you would make more power per pound of boost than you would on a car thats 9:5:1 or lower. Only thing is, you need to be careful how much boost you run. Play with the spark advance, and timing to adjust it.
