further planning, need some help

[tramp_drift240]

from what ive been reading and learning, a gt30r sounds like a good choice for what im going for. Hoping for around 350whp/wtq or somethin' like that, with the possibility to tune up higher if i feel the need down the road.

so im kinda set on the turbo, its a t3 flange, so i was thinking...PeakBoost manifold? externally gated turbo, manifold has the flange on it for a WG, sounds good to me.

anyone know how high that might sit in the engine bay, with the top mount and all.

and for the downpipe, should i go for the V-band option on the exhaust housing, and just get a 3" DP custom fabbed with the v-band connection to the turbo?

any help/constructive critisism is welcome, ive noticed ive learned a lot by just reading you guys casually talk about turbo setups.

GT30r is a really expensive turbo, a t3/t4 50 trim would be perfect for you and a lot cheaper, but thats on you. The gt30 has only 25 hp more top end capability than the t3/t4, and costs almost twice as much. I could also go on and on about the Borg Warner S series but.. Iv been doing enough of that recently lol. Check my FS link out if you want a quick overview on them.

Peakboost makes a good manifold.

Your turbo isnt going to sit that high, its going to be very close to the top of the valve cover though, a little below it. Not something you have to worry about if you buy a production manifold.

V-band is sweet. Coming from someone who has a 5 bolt Garrett style flange, i really wish i had v-band. One bolt and the downpipe disconnects from the turbo. Top mount manifolds almost always come with the task of making a custom downpipe unless you get the JGS kit or something.

[tramp_drift240]

where can i find "t3/t4" turbos. it sounds very generic. and are they BB?

that borg warner one youve got there has journal bearings, is it a t3? whats the exhaust flange on it for the DP (cant recall the term for it) 5 bolt, 4 bolt, v-band?

im just trying to get everything figured out, since im kinda iffy on the setup in its entirety.

[480sx]

Its a Garrett t3/t4 50 trim turbo with a .63 ar exhaust housing. Literally the 'perfect' turbo for our cars if your going for 450 hp or less. Its not ball bearing, although you CAN get it made in ball bearing. However the people who buy the t3/t4 with a BB center cartridge are usually pretty disappointed, because they dont spool nearly as fast as they had imagined. Seriously the difference between a BB turbo and a journal bearing turbo in spool up time is between 100-250 rpms. You cant rebuild a BB turbo either, you just buy another one.

The borg warner is a journal bearing turbo, t3. It comes with a 5 bolt Garrett style flange or a V-band. This turbo on my car spooled up 150 rpms later than my t3/t4 50 trim and has the ability to make 575 hp..

You can find the t3.t4 anywhere that sells turbos. I picked up a rebuild one that was brand new on ebay for 450. They usually go for about 600.

Seriously if you want it made easy and cheap, go with the JGS kit. 1000 bucks for most of your hardware except the turbo. I wouldnt get the turbo from them i would go with a Garrett unit over turbonetics, heard some real bad things about them recently. http://jgsturbo.com/index2.html

Seriously if you want it made easy and cheap, go with the JGS kit.

i dont think i said anything about wanting it cheap and easy, lol

im definitely wanting the peakboost manifold. and im totally down for getting a v-band downpipe with flex section fabbed up for my setup, if its 3"

ill definitely be looking into those turbos, are they just oil cooled, or oil lubed and water cooled?

and any idea how quickly itd spool to full boost? i dont wanna get punched with power at 6 or 7k.

with 350+, 50 trim sounds right, up to 450 or even 500 in some cases,

50 trims/30r/bw258/ spool between 3-4k (a 30r is a turd though, probably worst garrett turbo..., might as well save the cash and go with a different turbo)

35rs spool between 4k-5k

37+r's spool between 5k-7k

[tramp_drift240]

gt30r's the worst turbo, really?

i might be wanting a faster spool than a 35, but i am wanting to run normal at 300-350whp, and be able to go up higher if i wanted to, using the same turbo.

wasnt there a youtube video of a flat black ka-t hatch that was for sale or something, with a gt30? and it completely ripped.

yes, ive mainly been looking between the gt30r and the 35r, im just not sure which would be best for me, since im not wanting some killer lag.

keep chiming in, PrYdE

[GTR PrYdE]

ok I don't mean to piss off any other niconauts, but i spend and equal amount of time on my evo forum, and there's so many turbo/cam/everything tests that go on it's crazy... of course I don't have the cash that these guys do but i still enjoy all the results

ANYWAY!!!

the 30r has been proven to be laggy for its "power", 4500rpm spool on a 2.0 for 400whp..? you can get 450whp out of a 35r with the same spool...

I've mentioned in another thread that forced performance has modified the wheel on a 35r, to make it a hta35r and it spools very very nice while maintaining top end. i'm not part of fp but i've been really impressed with they're modded 35r...

everybody likes vids, the hta35r in it's prime

http://www.youtube.com/watch?v=IZx32APqUXM

[tramp_drift240]

yeah, you also said it was more pricey, which im not really wanting, since a gt35r is already like 12-1400 new, right?

so you think i should just bump it up to a gt35r?

[GTR PrYdE]

I dunno... do you plan on pushing 600+whp? if not go 50 trim, it's cheap,makes great power and very proven. if so, then by all means go 35r, and it'd be up to you if you wanted to shell out the extra for better spool on the 35r..

[tramp_drift240]

this trim stuff is confusing as hell.

max, ill want like 450 to the wheels. but ill be perfectly happy with 350ish. with somewhat decent spool up.

what turbos are in that range, hahaha

[GTR PrYdE]

lol the 50 trim is the only trim you need to know. it's just what the turbo's called and it's avail in .48 ar or .63, you'd probably want the .63 for topend and 450whp...

this is your basic cheap 50 trim, http://stores.teamblindside.com/Detail.bok?no=149

I have one and it has a 1yr warranty, so yeah pretty decent for not being garret

[tramp_drift240]

is that internally gated? ive been kinda looking forward to a 3" vband.

and itll end up having an external gate anyway...

[GTR PrYdE]

I wouldn't even bother with the internal gate, if you use a 5 bolt dp, like the jgs it blocks it off, or even any other 5 bolt ford flange- which is a very common t3 turbine outlet

I don't think band would work to great for this turbo either, it's only a 2.5" outlet..

for a 35r yeah 3" vband would rock

[ka-t 300]

I have a s14 with the peek boost mani and a garret t3/to4e with .57 trim journal bearing. I bought the package deal with the down pipe , waste gate, dump tube, turbo and mani. I have 15000 miles on the set up now with no issues and full boost at 3700 rpm. they use good materials but i had a lot of fittment issues with the mani and the down pipe. the mani had the waste gate flange welded on wrong and i couldn't bolt on my domp tube, also the turbo was hitting the hood soo i had to send it back for a redo lol , the down pipe i had to cut in 3 places and slightly angle and have it re-welded at my exspence. so it was a night mare for the money for me but like i said they use good materials. If i had it to do all over again i would use jgs. my turbo still sits real close to the hood, you can see on the hood where its rubbing on it from the motor raising up when it hits full boost lol

[tramp_drift240]

sounds like you need better/new motor mounts if your motor is moving that much.

plus thats an s14, i dont know how much the clearance difference is between s13s and 14s.

i already plan on having a downpipe fabbed custom, along with a dump tube custom made.

JGS doesnt seem to be on the same plane as a peakboost manifold.

for a 35r yeah 3" vband would rock

i still feel like im between a 30 and a 35r.

[ka-t 300]

no I put in new nismo mounts its just that close to the hood I even had to cut out a small section of the fram that supports the sheet metal of the hood . but it may fit differently on the s13. good luck if you go that route. custom down pipe is a good idea.

[ka-t 300]

Hoping for around 350whp/wtq or somethin' like that, with the possibility to tune up higher if i feel the need down the road.

jgs set up is plenty good for that pwer level !!!!!

[480sx]

4500rpm spool on a 2.0 for 400whp..? you can get 450whp out of a 35r with the same spool...

The 3071r spools a fvk load faster than a gt35. There is no possible way in hell that a 3071 spools at the same rate as a GT35.

However you are right about the 3071r, its not that great of a turbo IMO. Your much better off with a 50 trim t3/t4 for under 450 hp. The 3071 will only flow for like 475, so why are you going to spend the extra 600 dollars to get worse spool up than the 50 trim 25 extra hp.

Seriously man, the 50 trim t3/t4 is the best turbo for your goals hands down. 35r is simply bigger than you need it to be for your goals, your just going to have extra lag that you dont need for no benefit at all. People get all caught up on huge turbochargers when they chose one for their car, when in reality its all about picking the right turbo for your goals. IMO, a street car is all about response. Turbo lag while being fun for a bit gets old real quick.

[tramp_drift240]

i completely agree, i really dislike the thought of lag, but i would like to be able to crank it up at some point down the road and get some more power out of it.

i still cant really find any good examples of a 50 trim t3/t4. most ive found (iirc) are internally gated, which im not wanting. and im not particularly wanting a 5 bolt dp or a 2.5 inch outlet.

give me some solid suggestions for me to start reading through, if at all possible.

[480sx]

I can get you one thats been built with new parts by my friend. Dude builds turbos past factory spec, basically, you would rather get a turbo built by him than any factory. Owns a turbo shop, Timsturbos.com. Price would prly be around 600 i believe, maybe less.

Same thing that you would get from say.. This auction. http://cgi.ebay.com/ebaymotors...57185

The 50 trims are a really popular turbo you can find them everywhere for about 650-700 bucks.

[tramp_drift240]

that sounds good....

so its a t3 flange, is there any way i could get a 3" outlet or something? 2.25 is kinda small.

i like that its only oil cooled/lubed instead of oil and water combo.

and would i just get a four bolt flange and gasket in order to fab up a downpipe for that?

[GTR PrYdE]

The 3071r spools a fvk load faster than a gt35. There is no possible way in hell that a 3071 spools at the same rate as a GT35.

However you are right about the 3071r, its not that great of a turbo IMO.

Well I really meant the 3076r, but even the 3071 spools decent but cost twice the price of a 50 trim with very very similar results.

Tramp, 50 trim still sounded like best suited turbo... even though it's not vband or 3" out.

unless you plan to make 600whp don't go 35r, maybe give the s256/8 a try for over 500whp

[480sx]

that sounds good....

so its a t3 flange, is there any way i could get a 3" outlet or something? 2.25 is kinda small.

They dont make that type of compressor housing for the 50 trim. You really dont need it, its going to be more lag without any benefits. For your hotpipe you dont really need a large diameter pipe, its just going to create more lag. Ideally you want the same size hotpipe as your turbo outlet.

It would be a standard Garrett 5 bolt flange for the t3/t4 to get a downpipe made. The 4 bolts are usually found on the bigger turbos.

Like i say, if you wanted a 50 trim i can get you one at a good price thats going to come with a warranty and be hand built by a pro.

Pro > Factory assembly line

Well I really meant the 3076r, but even the 3071 spools decent but cost twice the price of a 50 trim with very very similar results.

Oh, still though, any gt30r is going to spool a crap load faster than a gt35. Your absolutley right about the 50 trim pretty much having the exact same results as a GT3071r though.

[tramp_drift240]

sorry, one last question, youve got me hooked on the 50 trim stuff "pro built" etc.

is it internal or external gate?

[480sx]

External gate, as are all real turbos. Internal gates choke hard for high boost. They are fine for stock levels of boost however, they just suck for anything more.

Shoot me an email if you want to ask anything else, or figure out a real price, emails in my profile.

[johnnyappleseed]

what mods do you need to go t3/t4 with peakboost mani without blowin the motor? for about 350? what mods do you have tramp?
