t04b(v-trim) Bolt on Discussion

[1029TSG]

Either way, but if you run this turbo with the stock parts, dont expect the best spool up or a Big HP gain. Although you will see some performance gains, just dont set your expectations to high. I know some of you have heard me say this, "The turbo is only as good as what's bolted to it". If it has a 3" intake and you run the stock snorkle or if the inlet and outlet are 2.5+" and you haven't ported or upgraded the manifold and elbow just dont expect the same results.

In the same vein, I'd think that an intercooler upgrade is practically a must for a turbo of this size, as much for airflow purposes as cooling, maybe even more. The stock SMIC is pretty restrictive.

 

[1029TSG]

I agree, in fact anytime you bolt on a turbo that can support 400+ HP and try and run stock components that are designed for 200 HP you will have a restriction.

I agree, I would get a 2 1/2" o2 housing (Mine was only $115 from punishment racing) And also port out your stock manifold(if you have a 2g) or upgrade to somthing bigger, I personally have the newest sbr manifold and it was only $275 shipped.

Also, Tuning.. It doesn't matter if you have every part in the upgrade list, Then it is time for the car to be tuned by yourself, Or professionally on a dyno for best results. Tuning is the key once you have all the parts.

 

[MaroonclipseGST]

I've decided to go ahead and buy a sbr manifold and larger o2 housing. As far as tuning goes i kno that i kno nothing and already have a dyno and tuner picked out, thank you.

 

[1029TSG]

Yes, if there's any of you that feel you aren't getting comparable results with other members on this thread please "tune". Many times spool up and overall HP can be improved by adjusting your air/fuel ratio and timing (if applicable).

Hey, I went with a massively ported 2g O2.
Do you think that will obstruct the flow much?
I ported the intake to it to 2.5", and the outlet is 2.5 also.
Do you know how big the Evo O2 comes stock, or what you were able to port it to?

The SBR manifold is awesome, fits the turbo just right, so does the evo3 o2 housing, mine is ported and fit just right

1. The water line is 3/8 soft copper.
2. No
3. water line to filter? you mean water pipe? Bend it with a tube bender.

I am in the middle of my install Day 6 (dont ask!!), and I have a couple questions.

1. What did you use for your rear water line. I cant make it out fully (copper?).
2. Will a stock banjo bolt work?
3. What did you do with the water line to your filter housing? It hits my compressor housing and not sure what to do with it?

This has been a huge mess for me, and I'm hating life right now.

Thank you... Big help there heres my update:

I tried using 3/8 aluminum pipe (purchased before your reply and a big mistake since it kept kinking). I then tried Aeroquip ASE100 line but chickened out (concerned about heat saturation). Lastly, I went to a hydraulic shop for the fittings w/barbed adapter on the ends, and had them make a SS braided line about 38" long. This replaced the supply line to the filter housing. So in all I blew about $40 in trial and error, before I found the combo that worked, but I'm satisifed with the results so far.

The rear water adapter would not work for anything. I purchased four seperate adapters that would thread into the housing but would make contact with the block before the 90 degree bend. I finally had to remove one of the bolts on the compressor side to make enough room for the adapter to swing around. When I installed the turbo this time, it just touches the block.

I copied your reuseage of the pipe bolt off the coolant supply line, that seems to be the only option as every adapter I put on would either be too long or not enough room for the hose. BTW what is the size bolt on that line? I need to know just in case I need to make one? I've pretty much got everything plumbed except for the oil drain line. The bolts that came with the kit dont fit. I finagled with them for about 5 minutes, they seem coarse as compared to the threading in the center section, so a trip to Lowes is in order in the morning for some 3/8-16 1" bolts, is in order. In all, this has been a hellatius install, but a big learning lesson for me. Kinda feel like I just climbed everest.

Has anyone installed this turbo with an external wastegate? Im trying to work everything out as far a pricing and such and I'm looking for a nice exhaust manifold with a turbo flange. I'm also looking for a nice downpipe (turboback) with and o2 eliminator. Any help would be great.

I've installed the t04E version.
The install would be exactly the same.
I posted pics on an eariler page on this thread.

Sounds like you are doing things the hard way!

I finally had to remove one of the bolts on the compressor side to make enough room for the adapter to swing around. When I installed the turbo this time, it just touches the block.

The thread is a 3/8ths pipe thread. True, you have to make room to install some of these. The resulting fitting should be no where near the block!

I am not sure what you mean by pipe bolt? You mean fittings? ok... I am going to be updating the web page with more pics really soon now. I'll be putting in a lot more descriptions on parts and procedures. NONE of the bolts are SAE! they are all metric. Don't force them!

 

[nazthug]

Just getting finished installing the turbo.

Kind of a pain in the ass.

Make sure that if you are doing this you absolutely buy the necessery bolts, such as the manifold to turbo bolts, and o2 housing bolts.

I've had a few problems, the elbow I purchased would't fit around my dejon lower i/c pipe, needed to dremel the hell out of it and I'm pretty sure it'll blow off if I boost. After mangling the hell out of the inlet I finally got it on.

The main issue i'm having now is the oil drain line bolts that came off my T25 WILL NOT fit the oil drain on the new one. Could you tell me what size bolts I need? Has anyone else has this issue?

do yourself a favor and buy the bullseye oil drain kit, its awesome quality, fits very well(just make sure you use the 45* bend on the bottom, not top, ) and it will fit just right

its very nic quality, doesnt leak so far and is a direct bolt on

UPDATE: I got the link installed, and am running 15psi, once in a while seeing about .4* of knock, at most, so not bad, i have it tuned conservatively, 15psi, 10.5 a/f and pulling 1* of timing where needed, and its an awesome feeling, given, i drove the s16g in the summer and this when its 55* outside, the power is awesomel

anything over 4000rpm just pulls straight to redline, no falloff at all, and it pulls very hard in 3rd gear, getting 15psi at about 3600rpm or so

I just gotta throw in the 750s and tune for more boost, but gotta wit till i get my clutch installed next week, the stocker is giving out at this power level

otherwise, i was very happy my JR FMIC piping and Dejon intake pipe fit up just right without any problems, the turbo clears most everything(fan housing has to be trimmed slightly for the actuator but thats because i have the sbr manifold with thicker flange)

OH david, sorry to tell you this, but i think im ready for the high boost actuator, this one works great, and goes low, but i might need to be able to go higher, so far i have been able to hold it steady at about 15psi, but if it wont hold 22 to redline, i might have to exchange it for the high pressure one

Otherwise, being able to run 10psi in first gear is awesome, almost no wheelspin, only towards redline, i love this torque curve, its just as it should be, without that stupid spike like the smaller turbos do, and spin the wheels and give you a false sense of speed

will be hitting the dyno mid feb at a meet down south, if not earlier here locally

update:

I've been driving on my T04B-H3 for a few days now and can definately say that this thing kicks major ass. I still need to tune the car a bit better, I have Jeff O's chip right now, but the turbo is awesmoe. I think I have a few boost leak issues with my forrester intake manifold's notrous bungs not being plugged with the right plugs so I don't want to estimate full boost just yet, right now it's about 3600 i'd say on 12-14 psi. I'll say that with my 264's this thing pulls all the way to 8500 and doesnt fall off at all. I wish I had a tranny that could shift higher because the car pulls soooo good from 3500 till 8500. Like I said, I need to tune it a bit, I'm going to get the downpipe bung welded into my exhause tomorrow or the next day and play around with fuel but untill then I'm very happy with the 12-14 psi and can't wait to see what this thing will do at 22!

oh yeah, my mods are in my profile.

 

[1029TSG]

That's all great news everyone. If you need more boost even on the low pressure actuator just shorten the rod.

 

[RavenX]

For those that have problems with the oil drain kit. Heres what i did. Since i didn't order the kit i modified my t-25 oil drain. My T4OB Vtrim came with a t3/t4 flange for the oil drain. So me and a friend went to the junkyard and pulled off the oil drain from a Volvo turbo. They come with the flange you need. All we did was cut off the flange from the volvo drain and modified the t-25 drain and it works. But save yourself the trouble and get the oil drain kit unless you want to be like me and do it the way i did. Also as for the bolts for the turbo oil drain i beleive they are 14 standard bolts. I took the turbo with me to a bolt shop and they were able to get me the bolts i needed so you can try that.

OK, here is the latest vversion of my install page.
Make any comments to it in theis thread, or msg me.

Nice pics quick question though. I noticed on the turbine pic that your turbo doesn't look like its clipped? Although its kinda blurry i was just curious to know and what turbo is it? Vtrim, H-3 etc etc?

Jay

 

[questhe]

That's a question I'd like to know the answer to also. Its a V-trim compressor.

I just trust Dave (1029tsg) that Bullseye sized the turbine wheel for the comp wheel.

Perhaps Dave can release the specs on the turbine wheels?

As far as clipping, there is no need. The turbine is more efficient and flows enough unclipped. The xducer is 2.5 inches!

Same thing for porting. A properly sized turbo needs neither. Porting and clipping are bandages for too-small turbos.

[1029TSG]

Yes, you are correct, porting and clipping are bandages for smaller turbos and too much of either one can result in unnecessary lag. If the housings A/R (.48-.63, sorry guys) the turbine wheel (2.54 exducer) and wastegate (38mm) are sized properly for your HP range, then no other modifications are necessary. With that being said, some of you will find that you have received a turbine wheel that has a small clip to it (approx. 8 degrees). This is a "factory" clip and is not anything that we have done at our facility. We simply order what ever our supplier has on the shelf and you could receive 1 of 3 different styles of turbine wheels. They are all the same size, its only the clip that makes them unique. There's no clip, which you've seen and these two pictured here that show the standard clip and the newest version (Gen III). I hope this helps.

 

[RavenX]

Seeing that the bottom one is mine are u saying i have a gen3 version?

 

[1029TSG]

Yes, that is correct. Most of our more recent shipments have come with that wheel. Although, there's no guarantee we will continue to receive that particular one in the future.

 

[questhe]

Looks to me like the top one (with white spot) is the more-clipped wheel.
I can see through all the blades.
On the bottom one I can only see through some of them.

Yes, that is correct. Most of our more recent shipments have come with that wheel. Although, there's no guarantee we will continue to receive that particular one in the future.

 

[1029TSG]

That's an excellent observation. Its not that it has more clip, it actually has less pitch.
