T04 front housing decision...

Postby gearhead313 » Wed Sep 29, 2004 7:35 pm

moving this topic over here...

I dug up another to4 front housing setup so now i have 3 to choose from. They are all .60a/r with different trims. Now that i have 3, im not sure what to use. I'd like to here other people's opinions on what would be the best for my application................and speaking of which, lemme c if i can start on that:

-bottom end will be fresh, but stock
-fuel will stay stock (inj/pump); possibly will put an adjustable fpr on it
-trying to run a different intake mani so i can setup a FMIC, probably something in the range of a 24x9x2 core, nothing fancy.
-managment will be an safc II for now. I have a few here, so im going to try to make that work. Would like to get a VPC or something to rid me of the afm...but i probably couldnt' afford to do one right now.

here's a pic of what i have with the numbers on it... the top little one is what i had on it. (wasn't real impressive at stock boost)...for the short time i drove it.

Arg.. not much to choose from. :(

if I had to , I guess the 55. Although it's too big for what you are going with.

Stock inj/pump will safely support approx. 275rwhp. So I suppose around 260ish AWHP.

That said, even the 55 trim is too big. You'd be better of going with a the new CT26 upgrade from ATS Racing if you are keeping stock fueling.

Cost around $850 with core. Upgraded to 46 or 50 trim (go 50). But this differs as the turbine housing, the most restrictive piece in the stock turbo, is modified to flow more.

For the power levels you are wanting at this time. It doesn't really warrant the cost of a custom setup. ie: manifold or adapter, rebuilding the turbo, etc..

Just my 2 psi.

well, since i have these just stocked, im not going to spend money on another turbo when theres over a half dozen sitting around the shop.

I kinda think the 55 would be best, but i wonder how much more id have to get into (fuel) to get the biggy on....

ats sells a couple of options on the cheap... bored out rail and modified fpr...

the stock pump is half decent... should be able to flow over 300awhp but the injectors are very limiting...

550's on a bored out rail with an fpr and youll put down some decent power :)

just becareful with the safc... those are motor killers.. infact i wouldnt recomend the modified fpr come to think of it.. ide only recomend an actual adjustable fpr... youll need it as you have to turn down the base pressure and richen up the safc in order to not blow your motor... unless you get something to control your timing that is ;)

ok, well earlier you said you found them laying around.. didn't mention that you stock parts that way. :P

Well in comparison, a well matched turbine wheel to a t04e 50 trim will flow enough for 350rwhp easy.

So, a 55 trim is going to be overkill, unless you like the extra lag.

You can try 550 and an Black box.. but you are entering stand alone EMS territory now. So be careful or you'll have a 3S-GTE sitting next to those turbo housing laying around. ;)

If you MUST go cheap on the fuel computer... atleast go megasquirt

i dont know why more people arent using these.. they seem like a really great set up to me.. for the price of an safc2 you could have a preasembled kit and it converts to speed density asswell

yep thats right

asswell

I consider stuff laying around.... 'in stock' :P

I have some rc550's also 'in stock', but they are the traditional dsm/honda style ones and dont know if they would work.

I am thinking going up to the 55trim and calling it good. I'll probably pick up the adj. fpr and maybe the bored out rail.

I do remember the timing issues everyone talks about. The safc II monitors knock, so i'll leave it, start tuning it and see how bad things get. IF i can't get the ping out of it, then maybe i'll lookinto a MSD BTM or something.


......and WHAT is a megasquirt???

megasquirt is a diy fuel computer.. they also have mega squirt n spark to control everything... but because you build it yourself its much much cheaper.. But even the preassembled ones are really freakin cheap too

ill probably end up using this on my 200sx
