Will my mods be enough for a T04B?
Hey guyz! I think I finally busted my stock turbo on my '88 TII, 'coz everytime I boost past 5psi I can feel my car slow down a bit or won't speed up any further. Anywayz, burnt turbo or not, I'm considering ordering a T04B, HKS manifold, And an HKS std. wastegate(?? psi). I guess my question is, with my existing modz is it safe to run the above items say about 14psi or lower if my engine is about 30k miles old??
My existing modz:
RB FCD
RB Full 3" exhaust w/ Corksport catback. (NO cat!)
Walbro FP (255L/hr)
Apexi cone filter sys.
NGK platinum plugs
Magnecor 10mm wires
Stock intercooler for now!
Trust T-Timer
Trust BOV type-S
TurboXs MBC
Premium gasoline...
Any help or suggestions would be greatly appreciated. Thanks!!!

no
buy a haltech ecu and a pair of 1600cc injectors + fuel rail. + few hundred bucks to tune it
plus a FMIC. plus custom downpipe to replace the RB one
plus custom oil and water lines
like $5000 total....
get your turbo rebuilt from BNR or similar. $600-700
then buy a S-afc and some 720cc injectors.
probably still want FMIC

I wouldn't. You'll definetaly need more fuel. At the very least bigger secondaries and a S-AFC. Realistically, you should run a standalone EMS like a Haltech, Microtech, etc. to tune fuel and timing. You'll need a new downpipe. You'll need a bigger IC and piping. And most importantly, you'll need someone to tune it all properly.

Thanks for the reply guyz! I really did think the T04B will be too big for my modz myself but I was hoping it could be done or at least just for the meantime, you know what I mean? Oh well, time to consider some other options... Any suggestions for what'd be the perfect turbo size other than a rebuilt stocker.. I'm really really pushing for an upgrade blower without spending $3Gs or more... How about other hybrid turbos or smaller than the T04B?? As alwayz, thanks again!!
~Chad
ps.
I forgot to mention before but I am of course going to order 720s or higher for my secondaries, a fuel regulator, and a S-AFC w/ the turbo I'm gonna get...

Thanks for mentioning that Ted.! I was actually looking at this one on E-bay... The seller says it's a P-trim.. http://cgi.ebay.com/ebaymotors/ws/eB...category=33742
If all he says about his auction true, it would be nice and cheap! What do you think?

"P-trim" doesn't mean anything except to describe the turbine wheel - this doesn't tell you power potential.
The seller does mention "The Compressor Is A 60.", but that sounds like compressor A/R, which means nothing.
The seller does post an H-trim compressor wheel map, but I think they just threw it up there at random?
If it was a true H-trim T04B, then the turbo is good for 350hp.

Alright.. I'm getting more confused of all these talk about bigger turbo and accesories.. I admit I have neither enough time nor the knowledge when it comes to turbo..!! Therefore, I'm just gonna go ahead and ask one of the so many final questions I have... Will the http://66.216.67.51/product.asp?0=220&1=364&3=728 work w/ my modz?(see 1st post). Has anyone go that way before and willing to share some intel about the unit? Reliability? Work quality? Etc..??
Thanks again guyz for baring with me!!
~Chad
Ps.
I only have this car for work so I'm really looking for a quick bolt-on upgrade that can be done after work and yet reliable enough for the track at least once a week.... Any new suggestions/ideas?? Ted I'm sure you have something for me...

that is what I said in my post. BNR upgrade or similar.
safe with S-afc and bigger injectors. probably want a FMIC as well.
should make 300RWHP pretty easy.

Quick turbo tutorial...
All that matters for turbo sizing is:
1) compressor wheel size (i.e. S-trim, V-trim, H-trim for T04B's)
2) turbine A/R
3) turbine wheel size (i.e. O-trim, P-trim, Q-trim for T04's)
Everything else don't matter. Compressor A/R don't really matter.
The "magic" power level for 13B's is 400hp (to the wheels) in my book.  This kinda power can be generated by these Garrett turbos:  60-1 T04B (accord to Turbonetics), T04E-60 (trim), T04S04/TS04/T04S
Almost everything else falls under those turbos sizes, as those are some of the largest T04's available.
Popular T04B sizes are:  S-trim, V-trim, H-trim - in ascending order.  The 60-1 is larger than all of these.
Popular T04E sizes are:  T04E-46 (trim), T04E-50 (trim), T04E-57 (trim) - in ascending order.  The T04E-60 (trim) is larger than all of those.
Check http://www.turboneticsinc.com/ for more info and specs for these models.
As for turbine side, use at least a P-trim turbine wheel.  Don't bother with O-trim wheels, as it's too small and a waste of exhaust efficiency.  "Collected" turbo manifolds run under 1.00 turbine A/R, like .8x to .9x - full divided turbo manifolds can run higher from 1.00 up to 1.3x.  I'll go into a short dissertation on why this is so at a later date...

I've noticed that 300rwhp seems to be the magic number a lot of people are aiming for. It's also going to depend on the hybrid. A v-trim wheel stuffed into the stock housing won't get you there. A nice to4 wheel and housing will, however I'm just hesistant to trust the safc at that power level.
I remember Chris ng had a safc with his s5 hybrid and put down 28x rwhp I believe, but it seems like most guys with hybrids and bandaids are falling just shy of that 300 mark. It would really be helpful if some hybrid turbo owners could show us some dynos, and then their supporting mods whether it be safc, fconn, or stand alone.

Yeah if you buy off E-bay that is true, and it is a bit cheaper, I just figure if you spend the money for manifold, wastegate, lines, the extra for the water cooled is nothing. You know. My opinion.

Here are some trim turbine numbers for you
N Trim Exducer Dia. 2.071 Major Dia. 2.92
O Trim Exducer Dia. 2.291 Major Dia. 2.922
P Trim E xducer Dia. 2.544 Major Dia 2.922
Q Trim Exducer Dia. 2.693 Major Dia. 3.111
P trim is good for 13b's and the Q is a bit larger
N Trim Exducer Dia. 2.071 Major Dia. 2.92
O Trim Exducer Dia. 2.291 Major Dia. 2.922
P Trim E xducer Dia. 2.544 Major Dia 2.922
Q Trim Exducer Dia. 2.693 Major Dia. 3.111
P trim is good for 13b's and the Q is a bit larger

Thanks for all your replies guyz... I'm sure they will be very helpful when I start canvasing for the right unit for my application... Needless to say, I'll be back for more questions later..
