how is this manifold better?

 

you know. that's a great question so i decided to call phil at spoolin and ask him just what the difference between his cast manifold and the inline pro is. here's what i got:

the inline has a slightly better wastegate placement since it's dead center and a smoother casting. flow and power production are very similar and 30 minutes with a die grinder can clean up the casting flaws very easily.

does make a guy wonder if that inline really is worth the extra money or not

 

i don't see why not go with a blox cast manifold. wastegate placement looks comparable to the inline pro

 

i THINK that's a new design for blox, someone correct me if i'm wrong but a couple years ago you could get blox turbo manifolds for $100 all day, then the price doubled. i noticed the same thing with it looking like an inline pro copy and you figure worst case with a little time and carbide bits you could remove the rough casting flash

i THINK all of these are tilted to use a 5 bolt turbo flange, i know the inline and spoolin are

the other thing is the wastgate and your hood. various posts have mentioned needing an elbow for the WG on a blox where as the inline can be ran straight. what i don't know is if a lower profile WG like the tial 38 will work straight on a blox?

chime in if anyone knows

 

sounds like the Inline Pro is the way to go. they have a wastegate too but i was thinking of opting for the Tial 38 instead.

 

Here’s a pic of the Blox on my car with and without the elbow. My wastegate cleared my hood without the elbow, but made running a dumptube difficult

what intercoolers are you guys running? i know Greddy has a kit. i'm not trying to be different or anything but i'd rather put something together instead so i understand what going in my car and so i get what i want the 1st time.

blu civic, thanks for the pictures and the info. i thanked racebum so i figured i'd thank you also lol.

are you happy with the power you're making or do you want more?

 

I'm using a Precision 350hp intercooler

i'm very satisfied with the power i'm making with no plans to go bigger. since i'm going to be tracking my car i was shooting for 250whp, but i'm good with what it made. keeping the engine 100% stock so when/if it blows, take it out and toss another one in and keep going.

 

i've been looking around for answers on my turbo choices..... it can get complicated. i went to the Road Race sight and Bullseye and found a few more threads i like.

i'm thinking the turbo that would suit me best is the t3/t4oe 57 trim. this may have been replaced/ updated by something newer by now so i'll be looking for that info. i guess going smaller than that is wheel spin wheel spin wheel spin with no top end and anything much bigger starts sacrificing spool, midrange, and driveability. correct me if i'm wrong.

 

Basically the PSI of boost isn't that important its the VOLUME of air that it can push which is.

For instance,

Tiny turbo pushing 14psi will be 'sucked' dry by the engine before it can make power.

Same engine with a bigger turbo pushing 14psi could blow the engine up because its CONSTANTLY pushing 14psi and not being 'sucked' dry by the engine.

 

one thought is the precision 5341b, i think it's the best buy in the category you're looking at. you get a full 360deg bearing, it's a t3/t4 in a 50 trim but flows 48lb/min it also comes standard with a stage 3 wheel. the full retail is $599, if you shop a bit $559 can be found. you also get 4 or 5 bolt cases for the same price. that alone is very useful if you are using a manifold designed for 5 bolt

 

i already understand this concept. thanks though

 

i thought the 50 trim was undersized for the cfm's the b16 head can flow and wouldn't be able to make power up top. correct me if i'm wrong. i contemplated the 50 trim but i kept seeing people complain about wheel spin and power falling off. wouldn't the 57 trim be the next step up in size and shift the power band up slightly and flow a little more cfm?

 

50 trims aren't all created equal, this one has....actually here's a link to the specs.

it's really similar to the now discontinued 5031e.

i had the same thoughts as you while im putting together the kit for my type r, both the shodan and phil at spoolin suggested a stage 3 upgraded 50 trim for the b18c.

that's exactly what the 5341b is

garrett makes one as well but it's $625 in 4 bolt only, the 5 bolt housing like i'll need for an inline raised the price to $700 and it only has the 270deg bearing

i actually ordered a 5031e only to receive a 5341b which is it's replacement

 

I apologize, I shoulda read the whole thread.

 

^^^ no problem man. i'm not a basher. give the thread a read and give a little advice if you can. thats what we're here for..... not to tear down people

 

so you run this turbo. whats your set up and how does it perform? dyno sheet?

so it sounds like the 5341b has the low end of the 50 trim but more up top....?

i emailed these guys hoping for a little advice.

 

haven't finished the build yet, it is technically a 50 trim but even the garrett compressor maps of a 50 with the stage 3 wheel and a 57 have similar top end output but the curve is better on the 50. the only benefit i could tell of a 57trim was the couple lbs/hr more it puts out. if you're going to rail it to the end maybe but the midrange of the 50 is better and both can use the .63 housing. the real question is what your power goal is. that's generally what you build your turbo around.

this is the 5341b with a temporary home in my kitchen

the shodan was EXTREMELY helpful with my build design and sent me in the right direction to learn quite a bit about proper turbo setups. between that and 8 or so hours of googling you can get a pretty solid idea of what's what. the one thing you DO want on a 50 or 57 is the .63 a/r the .48 will choke the top end. there is one mistake on the marketing though. the 5341b is not a 1.75" outlet, it's 2" and it really appears to be 2.75" on the inlet

 

i think i'll call to make sure on mistake in advertisement. so you bought yours through Titan Motorsports?

one last thing..... intercooler piping diameter and BOV's. i would like to run the Greddy type S. they come in 3 sizes; 16, 19, and 29mm. which one? and pipping diameter to match the turbo size?

i got mine through e motors for $559 which i do not recommend, took a month to get and about 10 phone calls. bogus tracking numbers and the run around.

i have no idea why titan has it advertised as a 1.75" outlet, i mean, the tape doesn't lie, look at the pics

we have a few forum vendors that are precision dealers and or look around your local area.

 

i looked through the vendors and found them. thanks. i wonder if Precision knows about this marketing mistake....?

 

no idea, i wondered the same thing which is the reason i took pics. i knew no one would believe me without proof.

at least this way people don't order the wrong couplers and then get pissed when they don't fit.

the question someone should ask precision is if they are available with different cases.

mine has .70 stamped in the cold side, .63 on the hot and the above measurements

 

i just figured this out.

1-3/4 and 2-5/8" are the inside diameters at the largest point of the turbo
