some pictures..........















after running around with this setup for about 2-3months i took it to the track and ran on street tires at street pressure, and ran 12.69@115.

went to the dyno and pulled 290.65whp--281.88wtq. on the way home from the dyno however...my stock timing finally caught up to me. fried ring lands anyone? time for round two i guess.....

pulling the motor back out









NEW PARTS FOR PART 2
-mega squirt v3.0
-crower rods
-*new JE pistons
-rternie ramhorn manifold
-holset hy35 turbo
-tial 38mm waste gate
-treadstone 25x10.5x3.5" intercooler
-3.55 transmission
-OBX lsd (need to order)
-battery relocated to trunk
-oil/water catch cans relocated to front bumper
the goal for this round is 400whp and running somewhere in the 11's on slicks.



some pics so far.....










VERY TIGHT FIT, so much for running an air filter. :x






BTW this is my "fake" engine. the head is junk, #2 sleeve has a hole in it the size of a baseball....

i will keep this updated as often as possible...i am a busy guy sometimes.

Looks very promising. Sweet job on squeezing all that power out of the SRT turbo.

yeah, but look where it got me

Yeah great job. But uh, don't you think you might have a few problems with the turbo being that close to the firewall? Going to sound horrible when the car is running and its banging together.

On the first setup 12.69@115mph.
290whp with a stock srt-4 IC and o2 housing? Color me impressed! Very cool.

yeah the turbo is going to be very close to the wall. i will most likely end up "massaging" the wall a little. right now there is about 1/4" clearance. plus i will be going with very hard mtr mounts. (80a-95a)


yup fusion, stock ic and o2. my engine guy did do some trick valve seats though. im guessing this helped quite a bit.

Any more info ?

I'm just curious

its been awhile since i had the head gone through. from what he was saying was, neon heads have a bad port design (compared to honda mostly) and i guess benefit quite a bit from a nice valve job.

i cant go a whole lot in depth on this as im not really that smart when it comes to it. if you want to know it all www.stewartengines.com e-mail them and ask them. tell them monday sent you. he is an awesome guy and is very smart.

That the manifold you bought from dmarino? I thought his had an external WG flange?

Shooting for 400whp? Very nice. keep us updated.

good thing your engine guy doesn't flowbench heads with his eyes.
stock for stock, a b-series head don't flow much differently than a dohc neon or pt head.
having huge inlet on an intake port doesn't mean it flows more.
we have an advantage on valve size and bore.

in full race setups, b-series ported heads perform very well,
they run significantly more lift which rewards them .400" - .600" lift

k-series is a different story. we lose.

yes this is the manifold dmarino was using. he was running an external gate.....only he set his up to gate off the turbine housing itself.


once again this is dmarino's setup. my turbo housing doesnt allow me to run mine this way, so i will be having an external gate welded onto this manifold. i am going to copy the way rternie did his.


dave99, dont shoot the messanger like i said i am not real educated in this subject, i am just telling you what i was told. most likely yes he said this after just giving it a quick "eye ball".....but i trust his "eyeballing". he does flow bench and has much experience with heads. he's good at what he does.

just a lil update. this is how my bumper beam looks now. main purpose of it is to keep my bumper nice and tidy.

Two questions:

1) How much boost were you running with that SRT-4 turbo to pull numbers like that?

2) How big is that Holset compared to a "50 trim" T3/T04 style turbo?

Thanks,

Thad

i was running 20psi on the srt turbo, which i will say now is tooooo much with stock timing and pump gas.

there really isnt a ton of data on the holset turbos to be honest. just looking at a holset beside a 50trim would make you think the holset was going to eat it for breakfast....but size doesnt always mean it is better.

http://www.dsmtuners.com/forums/showthread.php?t=145691 for the best info search here. i believe somewhere in that thread there are pictures of it beside a 50 trim. also you could find a 50trim map and look at them side by side...just take note that the maps on the first page are in cfm.

http://www.honda-tech.com/zerothread?id=1225182&page=46 this is a thread in a honda forum.

Any updates on the Holset project?

Also, from when you had the SRT-4 Turbo setup, would you happen to have any better pictures of how your intake tubing was routed, or how the routing was accomplished from the compressor to the intercooler?

Thanks!

Thad

I was wondering about this the other day.

I haven't really heard much from Matt in a while.

I dunno how he did it. But i used the stock srt-4 hardpipe and just relocated my bobble strut and bracket...

Are there any good pictures of that type of setup floating around anywhere?

Does the bobble still function?

Thanks! ! !

Thad

i dont think i have a picture from my old set up any more....i had the hot side custom made by a fab guy around my town, and let me tell you it was very curvy and was a pita to get in and out of there. i was able to keep the bobble though. the intake tube was basically a 90 right off the turbo in between the battery and head and then a 90 downward....pretty basic but also a pita to get in and out because of the brake lines and battery.

the project is still progressing slowly. i have a bunch of new pics i have been wanting to get up i just dont currently have a computer or the opperating cd for the program to get them off my phone.

i will say however that the megasquirt is all wired in, my front fascia has a "new" look, all the intercooler piping is finished, and engine parts are expected to be arriving any day now. i absolutely cant wait to drive it again.

p.s. keep an eye out for pics

Dont think so.. I may be the only one who has done it... and yes the bobble still works fine..

found this and thought it was cool. this is a holset hx35 next to a 50 trim.

well finally i came across a camera, so here are some updates


























electronic exhaust cutout



car should be up and running in a few weeks, i still need to buy the turbo (sc61) and finish the exhaust up. let me know what you think, thanks.

that thing is looking sweet! is that 3.0 tube gonna be able to take the boost? (serious question)

dont know for how long but dmarino has used/is still using one on his set-up

Been to over 20lbs here and it may grow like a balloon but it has yet to pop .

was wondering because my stock tubing had cracked at that seam.

not sure, i guess i will find out. its a pretty easy fix if it doesnt work though.

holy clean MS!

Impressive, too bad I'm not in Bloomington anymore... I would love to see this.

Same here. 8O

If you are serious about that it shouldn't be used. The turbo has to do a lot of work to expand it like that. Wouldn't be that hard to make a pipe.

Damn looks clean man. What front bumper is that i like it. What size injectors do u have. I have a SOHC Turbo neon too i want to boost around 15psi but i still have the stock injectors.

front bumper is a stock bumper that i took a 3.5" hole saw to. then connected the holes. injectors are 1000cc delphi.

i would suggest a 30lber or even some srt injectors if you want to change/modify the fuel rail.

So i should get a high flow fuel rail along with 30lb injectors. Kewl Thanks bro. Keep up the good work on the neon looks great so far.

i didnt say that. i meant to say, use 30lb "red tops" if you want to keep your stock fuel rail. if you are changing the fuel rail to say.....a lorenzo, then i would suggest srt injectors.

actually i would strongly suggest the rail/srt injectors. how much power are you trying to make? 15psi doesnt tell me much.

Will the srt-4 injectors just plug right in or do i also need the pig tail/wiring off of the srt-4

depends on the year of car. mine is a 97 and i had to replace the injector plugs. i ended up using plugs off a second gen. the easiest would be to get ahold of rs-autosport. they sell them there.

Oh well mines a 95 so i think i can use my early style plugs but if not i have some sec. gen ones too. Oh one more question will the stock srt-4 injectors work good on my car i still want it to be my daily driver so i don't want to mess up the driveability very much. I do have a cartech RRFPR. So i should be able to adjust my idle pressure so that its not flooding out because i will be dumping lots of fuel with these injectors. Any help on this would be greats. Thanks

i used srt S0 injectors witha chill factory rrfpr on my old setup. base pressure was 17psi. not the most ideal setup as idle pressure is so low the injectors (most likely) dont have a very nice conical spare pattern, but it works.

i would suggest megasquirt. you can do it cheap as, if not cheaper than a rrfpr setup.

Where can i buy a MegaSquirt set up at. So run the ms and the injectors right. Okay but i can use the injectors with my rrfrp for time being right until i can afford a MegaSquirt.Does the megasquirt get rid of my stock Pcm or do i keep it and just at the megasquirt. I don't know very much about the megasquirt.

you can buy a megasquirt, harness, and sensors from rs-autosport. they are great guys there and are very easy to buy from. yes you can use the rrfpr setup for the time being and go megasquirt later......although you will spend more money doing so. yes you can keep the stock pcm.

check out the megasquirt forum on here, it answers every question you asked in one of the stickys.
