HomeMade Turbo Kits

ASSISTANCE Forced Induction

well i have started my homemade turbo kit and picked up a Garrett/Airesearch TB0339 (T3 Series) turbo it came off a 85 saab turbo…im pretty sure it is capable of 7psi which is perfect for my needs i think

so lets start with the turbo specz

Compressor Trim: 50
Compressor housing A/R: .42
Turbine Trim: 69
Turbine housing A/R: .48
Internal Wastegate
Water cooled
Wastegate setting: 7 psi

im kinda new to the turbo scene so im not sure what manifold to use since the turbo has an internal wastegate can i use a td05 mani ?

my goal is atleast 200 whp with an ls is this a good number to shoot for with this turbo?

2

im assuming you’re boosting the stock b18a? well if so you will want to buy a b-series turbo manifold, made for a t3 flanged turbo… somebody correct me if im wrong but this turbo has a standard t3 flange?

3

You will have hard time getting 200 whp with this turbo at 7 psi… I have a similar turbo and at 6 psi, i’m pushing out 170 whp.

Get rid of the internal gate and get an external, you will be able to adjust it more easily if you want 200 whp.

4

how do i convert it to external? and 170 whp sounds good to me haha

hey, I don’t mean to thread jack (this may help the OP anyways), but I was wondering if you could tell us what RPM you get full boost at with that turbo, does it die off up top, and did you notice much difference in gas mileage? I got a brand new one of these .42/.48’s for a great price and am debating whether to use it for a little while or just get a T3/T4 50 or 57 trim now and ditch the little T3. thanks!

P.S. do you have any videos of your car or sound clips or anything? thanks again!

I get a full 6 psi at roughly 3200 RPM. It spools ultra fast. And for now, at 6 psi, it does not die at higher RPMs. (Cutoff is stock at 6800)

I’m planning on upping the boost at 10 psi this summer so I still don’t know how it’s gonna perform.

Here’s a 3rd gear dynorun:

BTW, 170 whp is not that much… You will want more than that once you tried boost!

yeah, your car sounds really good, and looks nice too. I am shooting for 230 WHP on however much boost it takes. I am guessing 10-11 psi. If that doesnt work out, I will drop in a 50 or 57 trim t3/t4 and try again. I just got the turbo brand new for a price I couldnt refuse, so I think I will give it a try. it is just for a DD anyways. Thank you for the videos and information! I really appreciate it, and it really makes me want boost now! I am building an engine though, and will be putting the turbo on that one. I am just doing forged pistons/rods/headstuds/gaskets/etc. and then a skunk2 intake manifold, 70mm TB and a little more.

im in love with boost she sounds so damn sexy hahaha i think 170 is enough how much torque u get?

9

170whp and 165ft/lb of torque. :burnout:

Pretty fun to drive. I said the same when I first tried it, 170 is enough… Yeah, right! After a month, I already wanted more. Shooting for something like 200-220 this summer. I will be rebuilding an engine to support more boost. My current high mileage one is still going strong, but I just don’t want to take any chances.

does any one know how you would hook up the water cooling system on a turbo like this? I’m considering using a saab 9000 turbo and they are also water cooled. ansewer could very well help us both.

12

you can run it inline with the tb coolant line

13

Answer: what’s that below your gauges on your a-pillar?

14

Homemade Dual Shift Light :slight_smile:

It was unplugged during dyno runs.

15

Where did you get this IC for $20?

16

i run a garrett t3 .42/.48 as well. it’s tuned at 10psi, and i must say it’s pretty fun. i’ve never had a chance to dyno it, so i don’t know any actual numbers. i do feel as though i’m over the 200 whp mark though. as stated above, you will want more. i lasted about a week, and i “wanted to make it faster”. all in good time, as this is plenty for now.

answer- dude in that second video of your dyno outside of the car u have some blow by issues to take care of. time for a catch can and a good vent setup. seriously i’m worried by the amount of blow by coming out ur valvecover breather. i’d highly suggest (like i do with all turbo setups) to run at the very least one vent port off the front of the valvecover and one off the back of the block. if u would like i can get u pics of what my valvecover looks like and what i’m talking about.

other then that nice numbers and i’m liking the quick spool

18

Yeah, I know about the blow by… This is my old, completely stock, high mileage engine (160000 miles)

I never cared about a vent setup since I will be rebuilding it soon. But I do plan on installing one. It would be great if you could post pics of your setup!

k well heres the setup off the engine. those are -12an fittings. plenty for the block fittings and valvecover. took some working to make them work with the valvecover but thank god its on a 94+ ls valvecover. impossible on the ugly shorter height 90-93 ls valvecover

well there u guys go
