As the topic states I want to buy a T3/T04E, in a 50 trim wheel stage 3 turbine specs .48ar and compressor specs would be .63ar, snail for my stock 98 SOHC VTEC motor. I was thinking of running some JE 9.0:1 slugs and Eagle Rods. Operations will be overseen by uberdata. I would like to run no more than 15psi until I can afford a real standalone and some other cosmetics. Anyone have any experience with this turbo on this motor and what whp predictions I could expect.

u don't have to limit urself to 15psi because of uberdata. if the tune is good there's no reason to old back. btw it's .60 a/r compressor with a 50 trim wheel. .48 a/r turbine with a stage 3 wheel. Quite a few people run that turbo on sohc's this site. If tuned right and you don't have any major holdbacks (restricted exhaust, etc) my guess is @ 15psi you cuold make between 270 and 300whp. that's only a guesstimate though. as D15B7turbo said... let us know.

I know that the D16Y8 head cannot flow as much as a B series DOHC VTEC head. But I still believe the theory is the same. Lately on H-T I've seen tons of B series guys running low amounts of boost making extremely good numbers. I.E. GSR motors making 300+ on 10psi or more with stock internals. I believe the same can be had on the trusty D16Y8 block without any significant mods IMO rods and pistons should be enough. My goal is 300 on 15psi. I believe that turbo should get me there, but maybe the 57 trim wheel or 60 trim wheel would be a better option. I would like to run 12's with my setup, without too much abuse, so that reliability will not be that big of an issue. If it last another year I'd be happy. Please feel free to comment.

yah ur right the head is the main setback of the d's. open it up ull make a lot more power. also turbo sizing makes a diff... if u notice a lot of the 300whp+ b-series are running like 60 trims and sc61's, etc. my friend's turbo ls makes 300whp on a 60 trim @ 15psi and another friend's gsr made 300whp @ 10psi on that same exact turbo (i mean that literally lol). and yah people have made 400whp on stock sleeve d16s with rods n pistons and that turbo (but with the .63 a/r turbine). granted it was @ 30psi hehe. 12's should be fine @ like 16-18psi i think. pm ELSpool on here. he ran i think 12.5 with just about 300whp @ 17psi if i remember right.

personal thanx to a real Tech-Buddy Marc a.k.a CivicRyda2k...thank you once again for the info...please anymore ideas and comments would be appreciated I'd really like to narrow down which turbo would be best suited for my hp goals...12's in the quarter and to whoop on the BMW's and boxsters on the road course...

Project_SOHC_EX

Can someone clarify for me. What is that has these Honda motors making such good numbers? CivicRyda2k says that(but with the .63 a/r turbine) 300whp should be attainable. Now I feel really confused because I thought it's the size of the compressor that will ultimately tell the final test. I thought the turbine just determines spool time. Thus my reasoning for wanting a T3/T04E with a .48ar turbine and .63ar compressor housing. So what is it bigger turbine ar the better numbers on low boost or did I have it correct. Small turbine big compressor=good numbers. One last comment I spoke with a gentlemen over at Precision maybe 6months ago in regards to possible turbo options and if I recall correctly he mentioned something about ar's and i believe his theory is this yes a smaller ar will ensure a faster spool time but what you sacrifice is top end power...Most people complain about lag but IMO lag isn't that bad(speaking in relative turns)...**** it'll save me some damn tires that's for sure...Basically the boost will come on more progressively...please more tech...I eat sleep and **** info...Please more comments...and anyone know how I can contact "ElSpool?"

If you plan on road racing this set-up i would go with a smaller, faster spooling turbo and just run a higher amount of boost to attain your goal. I run a t3/t04 E housing (.48 ar rear) and on my d15b running a lovefab manifold and open 3inch downpipe i dont see full boost (12lbs) untill about 4500rpm. You also might want to look into some of the faster spooling garret turbos, maybe a gt28rs. You can still attain your power goals, you just need to run more psi.

Project_SOHC_EX

Thanx Devine...Know where I can get a map of the GT28rs turbocharger by Garrett...One thing I know Honda's make strong blocks but at the same time I'm worried about the sleeves on my motor that's the only reason I planned on running 15psi, but let me not be a hypocrite I know how boost goes...You're never satisfied, but at the same toaken comfortably/reliably I would like to make 300whp running on 15psi. Keep in mind this will still be daily driven just when the events come up I would like to have shall we call it " A REAL WEEKEND ROAD WARRIOR." Thanks and keep'em coming

M.A.R.C.

smaller turbine = quicker spool, less top end power (in comparison)
bigger turbine = slower spool, more top end power (less restriction)

i didn't say u need the .63 to make 300whp. i just told u that a sohc was makign 400whp on a 50 trim with a .63 a/r turbine. you can PM ELSpool thru here... just search for posts made by that name

You're probably talking about ARFab and they actually made that power with the .48 A/R turbine.

exactly who i was talking about. i thought it was .63 though

Nope, I just found out the other day that it was a .48 A/R. I've been really curious too since that is the turbo I will be using.
