turbo Q

[Superist1]

i've tried searching and to no avail. Does anyone know how well a stock 03 wrx turbo will work on a ka24e? I believe i'ts a td04 flange and it can go to about 14lbs of boost. the only reason I ask is I got a friend of mine that has one for about 100.00 bux and figured it might work but I figured I'd ask ya'll

[nismofly]

iirc someone asked about one a few months ago and theyre too small

How can you say it's to small if you don't know his power goals? not eveyone wants to build a 400hp KA....

[nismofly]

well everyone does eventually get tired of like 190-200 ish rwhp, which i what i believe it would make if im thinking of the right turbo

WRXs push more than 200whp on the stock turbo...

I can't see it being much worse than an SR turbo...

[nismofly]

which is also considered too small for the ka

as i stated, people will say theyll be fine with x horsepower, but eventually theyll want more

thats why i plan to start around 230 ish, i can just up it in 40 hp or so increments and buy the supporting parts to go along until im permenantly satisfied

i still plan on starting with a t3/t04e, because i can start at like 8-10 psi, then up it until i can afford the gt3071r, my weapon for higher power levels

*:edit:* to the original poster, if your on a budget and want a used turbo, better starting off with a t3 off a z31 or something, it can be used for the same principle that i mentioned

[nissanfanatic]

after driving a stock S13 for one year, 250whp was pretty interesting.

I say this would be a great setup for someone that needs restriction to keep them from going too far on a small budget. And anyone asking about a $100 turbo sounds like they are on a budget to me.

[Superist1]

I am on a budget, but I'm only looking for 8-10lbs of boost. Until my back up motor gats built. heres my basic set up, wrx 450cc injectors,wrx turbo,and using his tmic as a smic,greedy emanage ultimate,and a desent boost controller. I'm planning on the e manage because I only want to but the managment once. but just in case the 8-10 lbs is not enough for i at lease will have a better understanding of what exactly I'm looking for. I mean I can look at numbers all day and I could really enjoy 8-10 lbs or I could get power hungry and need more.

[nismofly]

8-10 lbs on that youre talking like 190 rwhp or so id say, its going to feel better but youll be wanting more quickly

now 8-10 on a z31 t3 would probably more into the low 200s

remember the psi of boost makes different power from one turbo to another, you could run 10 psi on a gt35 and be making 360 rwhp, your goal should be more a power number than a boost number

[BlackFlag_s13]

Ya Nismofly, I feel you. My plan is to start with a fully built motor with the components to support 400whp out of a GT32r, but before that I'll either have a T3 Super60 or a T3/T4 to start with depending on which is cheaper. Im planning on running around 10psi for about 250whp and bumping up the boost every month or so until the turbo looses it's efficiency and then I'll throw on the GT32 and do the same thing. It's less of a headache... plus I'm not desperate to go turbo right away to warrant building a cheap kit in which all the parts will eventually get replaced. I guess great minds think alike, eh?

[Superist1]

the reason for watching the boost is that the SOHC is said to be safe at up to 10lbs. And I completely understand that different turbos will generate different amounts of actual power at the same boost. smal turbo(t3) @ 8 lbs is big turbo(gt35r) @5lbs. not exactally but but basic idea. because the bigger turbo may be lagger but will move more VE. I think this is the correct terms. do you the specs of that turbo and maby how to run it through the turbo caculator and post a pic of the map. I've been having bad luck at the junk yards near here in finding turbos and I know how this one is and how hard it's been pushed. Do you know some one selling a t3 like the one you mentioned?

[BlackFlag_s13]

For a Z31 T3 I'd hit up your local junkyard and grab one for cheap. Other than that you could probably find on in the classifieds... maybe even one thats already been rebuilt for cheap.

um stock block right? there are multiple sohc's running around with well over 300 rwhp, and veilside180sx is building one that should be up in the 600s

[Superist1]

I've seem a couple of posts about the limits of the stock block. I've seen ths sticky on th KA-T forum on the SOHC build up and the rwhp to mods list.(very informative). http://www.ka-t.org/forums/viewtopic.php?t=5597. not to anger anyone but just a very good link for the SOHC. But here is the noob thought of the year, but I thought that the TD04 turbos were bigger than T3's. Just because I found his turbo to be kinda laggy even when shifting between gears on his 2.0l, so I thought it would be a desent turbo for the KA.

[nismofly]

when you say "kind of laggy", does that mean, 2800 rpm full boost, or 3700 rpm full boost

i thought the t3 was bigger, i see a lot of turbo upgrades for wrx's that only make about 250 rwhp, making me think the wrx turbo on the ej20 probably runs out of steam at around 230ish on that engine, so id think the t3 would be bigger because they can run more in the high 200s

plus in that thread i linked to they talk about the t3 being bigger and a better suited turbo for the ka than the wrx turbo

[Superist1]

I'm talking about when you go full throttle and shift every gear it feels like every time you shift you wait the a second or two later you start to feel it. if that make any sense. Now I also driven my friends 04 STI with the APS SR 50(i believe it's last years model)and about 19lbs and that thing just screams when you shift as soon as the clutch is engaded the car rockets. what about the IHI turbos like vf 39. I believe it's an upgraded sti turbo. I'll probably end up with a T3 of some sort but just want to make sure I've explored most of the opportunites(sp) that come my way. Mostly because of the price.

[nismofly]

yeah i can see where youre coming from with the price

like i said my point was mainly referencing that other thread

what kind of flanges are on the wrx turbos?

[Kenrik]

I for one am runing a smaller turbo because I want less lag and am only looking for 200whp if I want more boost at some point.. (we are talking a while down the road...) Then I will just buy a bigger turbo. I am happy with my $100 turbo ATM...

[Superist1]

What about diesel turbos. Like the cummings,powerstroke,or the chevy turbos. Could I even spool them?And if I could would I be creating compressor surge?

[Kenrik]

My brother has a cummings turbo diesel in his dodge. I did not get the AR from it but to me it looked kinda small compaired to the turbos some guys have on their KAs

[Superist1]

how much boost do they push stock?

[Superist1]

from what I can tell they are bigger than a t3 and I have pictures but do not know how to upload them. I've got them in my email account, if that make any difference.

[Chezedik]

It seems to me that when I look at the two maps that it is a matter of how much boost you are running. The t3 being better for higher levels of boost. Of course, this also assumes that it is a 15G wheel. I am however using a T3 from the Z because I think that if you decided you wanted to step up to the plate later, you could get a T4 wheel housing and backing plate, and get some more love.

[Superist1]

what about the turbo diesel turbos off a 95 cummins? or some thing like that.

[C-Kwik]

Depends. You'll need to find out what turbo they use, but I'd speculate they are turbos Tuned for efficiency at moderate boost levels and low relative airflow. The V8 versions will probably use a turbo that might seem big for a 4-cylinder, but smallish for a large engine. I would hate to speculate though. Find out what turbo they are running and we'll probably have a good answer for you.

umm not everyone needs 400 hp to kick ***, or feel accomplished with their car. numbers games are boring. learn how to drive and appreciate balance. my friends stock engine 240sx can really kick *** on any curvy road. 350hp wrx's and rx7's can barely keep up... they only gain in the straight line, then he's back on top of em again. he could benefit from more power, but he's a good driver so he deserves to move up. don't just lay down 400 hp and then crash into a tree. it feels a lot worse than being a little slower, i promise.
