hey guys, i know this probably sounds like a real noobish question, and yes i have read the turbo guide an searched (both done repeatedly) but i was just curious about something. Im gonna be putting together my turbo kit in the near future and was just wondering, since there are many different manifolds, and many different turbos, and i know that each one might have different “flanges?” (the piece the the turbo and manifold connect to eachother.) So what would be wise to look for or buy first? The turbo and then find a manifold that would mate to it with no custom fabrication? or a manifold and then try to find a turbo that would fit and mate perfectly. If anyone could give a list, or mention what combo they have (manifold & turbo) and if they had to change anything to get them to work together, or if you had any clearance problems.
P.S. The car is not going to have power steering or air conditoning, so these are not issues. Thanks guys.
PS> has anyone bought those “XS POWER” turbos from stone mountain or whatever, they have em on ebay for like 250$, just wondering if anyone had, or experienced them. thanks.
Figure out what size turbo is best for your goals/application and what flange will be on that turbo determines what manifold flange to get your self.
There is always the option of adapter plates too if you find a killer deal on either.

Stay away…
Thanks, well i wanted to go with a T3/T4 turbo sice it seems like thats what most people are going with. The block im using is freshly built with forged 8:5.1 pistons and eagle rods, and a completely stock head. I was planning on running like 8lbs as a daily driver, and 12lbs on the weekeneds when i take it out to the track or the hangouts down here. Its not my only car but i’d like it to last atleast a couple of years. I figure with the block being built it should be ok running 12lbs daily, but dont wanna risk it. I’d be happy if the car was in the 200-250 horses (to the wheels) range if that’s possible with a T3/T4 at 12lbs. What do you think?
By the way, how can you tell by the turbo specs, when the turbo is going to spool up, or be at full boost? Is there a list or site that has all the most common turbos/ turbo combos, with info like that?
You find the compressor maps for that turbo and you plot the flow and where you would be in that turbos map with the engine you are intending to use.
Its a bit of calculations.
Search “turbo compressor map” and variations of that on Google
Allright, thanks. just curious, what setup do you have? turbo specs and manifold, what type of flanges are the two?
hey, at this site, you can click the different trims and it shows you a map (picture) how can you tell what is better? they just look round football shaped graphs, some go up sooner, but then go down sooner? does that mean the turbo begins to ease up?
