Default turbo choice on f+t 8 valve

I was planning on keeping this build mostly stock but that it quickly going out the window. The original plan was to use a reclocked 15g but I think I want more. So, the goals at this point are looking towards 250-270 wheel horsepower. I have a big valve kit coming and an enem v16 on the way too. I'm thinking ill need to run 16-18psi to get to those power numbers. I dont really want to drop $1500 on a turbo so I've been looking at t3/t4 50 trim turbos. What do you all suggest or what are you using to make the numbers you are? Or should I just sack up and go gt3076r or something else equally fancy?

Big valves and a V16 T cam. That'll help a lot. If response isn't critical then the regular bearing T3/T4 jobs are very affordable. Wouldn't the popular 19T mitsubishi support this power? I'm sure something like what an 850R or S60 T5 uses would work well with the budget. Then there is the K24 from the S60R cars. That's a stock 300hp turbo so should work well for you.

Using a ported 90+ exhaust manifold?

Yes, I've got a 90+ that I need to have milled flat. I actually have two of them.

That 19t will choke the car imo. As much as I like the 57 trims I think you should go with something with a better design. Why not one of these guys,

^You'd do something like a .63 T3 housing?

All of the cool turbos are externally gated?

External is the way to go. I would just Weld a 38mm gate into the exhaust housing or the manifold.

You could run an EFR but those are beaucoup bucks. I think the ATP Wastegate only fit the 2871's (which would get you there and be responsive, but I'm assuming price is a factor here).

something something scope creep

This whole thing is scope creep like whoa. I cant help myself. I keep doing the, well if I'm going to do this I might as well do it big/right. I'm sure a ball bearing gtx turbo is a fantastic turbo but 1800 for a turbo and then another 200 or so for the external gate is too much for me to swing my purse at.

Evo 16G and make a nice twinscroll header for it.

Remember response, power and $$ is always a tradeoff.

+1. Get a new eBay 16g, fabricate a j pipe manifold. Probably do it all for $500-600. I don't know why more people don't go this route.

16G's are a good option too, I even have one or three genuine units I can sell him. Haha.
Those Borg SX-E units are sweet; For that specific one I was hoping to have some real world numbers of what they do on these engines, but so far I've only completed the BMW thing I've been missing with. Life getting in the way and all that.

I know one could also go the route of welding the EWG flange onto the turbine housing, but then the multi-page argument of theoretical flow impact and turbulence starts, and once we go down that road it usually ends in a lock with no answer. The most recent iteration was pretty civil, though.

All of this is probably overkill for +/- 300 WHP though.

Fake ninja - You could indeed J Pipe it. Kinda heavy so will need to be braced.

Do note that if you buy any EFR new they do not come with turbine housings... so what he is asking is pretty fair, in my own dumb opinion.

t5 transmission. I'd like say 3k-6500/7k of power band I guess. I'll have enough cam and head stuff so rev it if I want to so I'd like to be able to use it.

your choices are fairly vast then within that range. on the budget side, you could get a 50 trim with a stage 3 or 5 wheel, that'd be on the larger side of what you need (and really probably a much better choice for the red wagon), t3 super-60's are in that range hp wise, for the more spendy of course there are various GT type turbos. The 3076 on the blue car is really pretty nice. boost control would be better with an external gate, however, they do offer a cosworth style housing option for that turbo that probably does fairly well too, and would allow you to keep el interno gateo

I can ask greg, but his recommendations tend to favor the better flowing honda applications and not as much the square hole volvo applications lol. If you need a price on a particular turbo, hit me up and I'll see what I can do.

I sold it last week. Thanks for the plug though.

OP, are you going to want more power in the future, or are you sure you only want 250-270? Also, how fixed are you on the 3k lower limit of your powerband?

I mean, I say that I'd be good at 250-270, but who knows. The plan is to be able to daily drive this car so I don't want it to get so race car that it's unreliable or not driveable around town.

Nothing is set in stone but I don't want something that doesn't make any boost until 5k. It's a f+t motor so it won't be a super dog off boost but I don't want an all or nothing set up.

Boosting along.

This is done with a T04BV trim, .63 a/r turbine housing, ATP ultimate wastegate, stage III turbine wheel on a Dodge 2.2 8 valves with a big valves head, boost from min 7psi at 3.5k creeping slowly to 12.5psi at 6.5k (by accidental design and no boost creep issue once min boost is turned up) . T04E 50 trim wheel would be a more efficient wheel which means it will make even more power at the same boost level and wider powerband.




Top red line is boost.
