internal or external wastegate poll

[Rease3]

which is better a internal or external wastegate?

[Psych Nah]

Ive heard external is better. I know a little somethin somethin...little.

[Sohc Wrath]

Both have their + and -, it depends on your setup and power goals.

[Rease3]

what are +'s -'s of both

[superdewey58]

i believe internal can spool faster, and i think i herd external is more reliable and less likely to creep.

i could definately be wrong though, so maybee someone else knows 4 sure

Im with him.:D

[CoreyR]

you wont spool any faster with an internal than you will with external. the only benefit to internal is price and space.

[Misfit]

biggest difference is price in my book, external is better for higher boost applications. internal is fine for 8psi and lower. depending on the turbo of course. if you want something to autocross with then internal is the way to go. serious drag racers typically use external. i prefer external personally, but of course im still NA

[lsturbohatch10]

my turbo will be internal for a little while. till i start upgrading stuff

[Rease3]

thanks for the information im only going to use 10lbs at the max im still tryin 2 figure out what my whole setup is going to be..whats a good mani that will clear the ac and ps?

[icarusdown]

A/C, P/S clearance = custom log w/ external gate flange.

external = better response + nasty open exhaust under boost :TU: (though more expensive...)

[Rease3]

wheres a good place to get a custom log...is cc-fab good?

[CoreyR]

wheres a good place to get a custom log...is cc-fab good?

ive heard some good things and some bad things ;)

[ryan89crx]

wheres a good place to get a custom log...is cc-fab good?do a search on ccfab and make a decision as to whether or not you want to buy from them...

[Rease3]

i found a kit from ssac it comes wit a mani a T3 Turbo with Garrett Internals and a downpipe for only 399 it looks like this http://www.ssautochrome.com/level.itml/icOid/images/aaaa10113_a.jpg i think i would have to get a wg for it just wanted to check

[ryan89crx]

piss on ssauto manis and DPs, garbage...

[Rease3]

so its not worth it?

[ryan89crx]

so its not worth it?IMO, no. i like to keep my turbo in the engine bay, not on the highway behind me...

[Rease3]

haha where else can i get a kit like that and where can i get turbo's from (used)

[konigcivic]

some internals can hold solid boost, some cant.

for externals, if the placement is correct there should be no boost issues at all.


ssautochrome wastegates ftw. do not buy the turbo kits or manifolds.

[MyblkVTEC]

i believe internal can spool faster, and i think i herd external is more reliable and less likely to creep.

i could definately be wrong though, so maybee someone else knows 4 sure

yup.... I agree

[Rease3]

noob question i guess what is ftw

[ryan89crx]

noob question i guess what is ftwfor the win

ssaoto/xspower WGs are great!! and for $70 shipped, you cant go wrong :TU:

[Rease3]

rep for that 1 ok now where can i get turbo's from i was on here and foundt a site buh i lost it

[ryan89crx]

i always reccomend www.blaastperformance.com

[Rease3]

any used turbo websites

unless u get the wrong spring..lol. thats just my luck i wouldnt worry about it. i dont know when u plan on buying ur turbo but i just took a chance on this one

they haev a t3 thats not up there, thats the one i got. ive only been running this one for a week but so far so good

[Sohc Wrath]

IMO, no. i like to keep my turbo in the engine bay, not on the highway behind me...

So very true, my buddys turbosmart wastegate fell off on the highway when he was doing about 90. The mani's are absolute junk, the wastegate flange just cracked off and bye bye went the wastegate LOL...

[Got Vtec?]

I would like to get external with my next setup. They are more reliable than internal, and they also add some eye cany under the hood.

[ryan89crx]

if they were, every factory turbo car would have external. i only know of 1 or 2 that came factory with external gates. the rest were ALL internal

[jimmyb34]

where is the poll at y0?!?!?!
if i ever go turbo external ftw

Wastegates
On the exhaust side, a Wastegates provides us a means to control the boost pressure of the engine. Some commercial diesel applications do not use a Wastegates at all. This type of system is called a free-floating turbocharger.

However, the vast majority of gasoline performance applications require a Wastegates. There are two (2) configurations of Wastegates, internal or external. Both internal and external Wastegates provide a means to bypass exhaust flow from the turbine wheel. Bypassing this energy (e.g. exhaust flow) reduces the power driving the turbine wheel to match the power required for a given boost level. Similar to the BOV, the Wastegates uses boost pressure and spring force to regulate the flow bypassing the turbine.

Internal Wastegates are built into the turbine housing and consist of a “flapper” valve, crank arm, rod end, and pneumatic actuator. It is important to connect this actuator only to boost pressure; i.e. it is not designed to handle vacuum and as such should not be referenced to an intake manifold.


External Wastegates are added to the exhaust plumbing on the exhaust manifold or header. The advantage of external Wastegates is that the bypassed flow can be reintroduced into the exhaust stream further downstream of the turbine. This tends to
improve the turbine’s performance. On racing applications, this Wastegated exhaust flow can be vented directly to atmosphere.

read corky bell's book maximum boost

[X292J]

External WG FTW, its just better.

[ryan89crx]

i dont think i would ever go back to internal gate. i like to have the ability to customize how my WG dump is routed/located

[Misfit]

if you have a ton of money get a lovefab mani and whatever wastegate they suggested. ive never had any experience with the wastegate, but the lovefab manis are beautiful.

[Clutchmaster]

dang so ssautocrome is garbage huh?
good thing i didn't buy any of my shit from them

[Rease3]

me either i bought a t3 airesearch turbo from the junkyard and a log mani from cc-fab
