what kind of turbo and who makes it? looks like a T3/04? also, who makes the pistons?

[JDM_1990_S13]

pistons are custom JE's and the turbo is a turbonetics T3/To4E 50 Trin w/ stage 3 .63 turbine. 550 injectors, and more goodies decorating my room, more pics to come.. all ordered from top end in cali.

[chezina]

Very, very nice room decoration !How much did u pay for the pistons?

[kilipo4]

I've heard some bad things about top-end. Hopefully you won't have any problems.

[boost_boy]

Nice toys:D Are those pistons stock bore or are they over-sized?

[nomore_mr2]

why not a bigger turbo? i know i am gonna get flamed for that one hahahah. the last big toy is still on the way right

[boost_boy]

Quote »why not a bigger turbo?[/quote] I'm gonna do my best to stay out that one. Too big of a turbo on this motor and streetability becomes very boring. Maybe this size is big enough t3/T04E 57 trim 60-1 stage 3 P trim (on the left) The one on the right is a T3/T04E 60-1 stage O-trim and it didn't come on to boost until 4000rpm.

[TrueSlide]

them pistons look so good I would hang them up in my room

[TrueSlide]

I would guess they are oversized pistons though, cause his sig says CA19.

haha big enough is that ever the case. i think my t04r is big enough until i go ca20 then the t51r ball bearing goes on baby!!!!

[slw240sx]

what do you guys think should i upgrade my turbo to, a t-28 or skip it and go t3/o4 ?

[boost_boy]

Quote »what do you guys think should i upgrade my turbo to, a t-28 or skip it and go t3/o4 ?[/quote] For better flexibility, efficiency and just plain 'ol better, do with the hybrid. A T28 is not going to allow you to hang around 20 psi as it will self-destruct. And a T25:D Major joke.

[JDM_1990_S13]

that turbonetics T3/T04E 50 trim w/ .63 turbine is great for a street car/weekend warrior that will run between 12-24psi (12 street-20 race fuel etc) on 15-2000cc motors and with the right cams etc can produce up to about 400WHP and maybe more with a bigger turbine housing like .86 T3 or T31, (IMO) i think that this is the best turbo for a street driven CA18 that races occasionally, boost should come on about 2200rpm and be at full boost at about 4000. I am hopeing that some 260 cams will wake up the low end, as i have heard that the tomei cams can produce up 35HP between 3-6000rpm so that should help it out allot in spooling things up. I think the 60 Trim will be better suited to a 2.0-2.4 4-banger. and as soemone once told me the 50 Trim owns the 57 trim (compare comp maps and see what i mean) and the 60 trim owns both of them if you have the juice to spool it up.

the pistons are kinda the same specs as the JUN Super Pistons i gave them those specs to copy pretty much. but they are 84 mm 8.5 CR i'll dig up the specs.

can't wait to get it going..

i do allot of long wining mountian road driving to get to the local surfing spots around trinidad so i need a car with a good long powerband, good lowend grunt and pull out of the corners and great top end to get up the highway fast, all that and still turn up the boost once a month and scare the local honda boys when i shake down 12's down the 1320.

[JDM_1990_S13]

should i get rods is the next majour question, i got quotes from both crower and pauter... i am trying to convince myself that the stock ones can take it, but holly crap if i turn up the boost and a rod lets go at 7000rpm... EEEK.. buying rods will make this thing take longer as money is tight...what the most power anyone has made on stock rods 400hp ???

rods or a cam kit from Tomei that's the majour decision here.

[boost_boy]

312.5hp to the wheels at 18psi equates to how much at the crank? I've run the engine on the highway at 25psi and the engine just laughed at me (all stock internals). On my drag sentra I too am using the stock rods which had been re-shotpeened for greater endurance. It takes too long for the rods to get made. oh yeah, carrillo rods have them in stock, but they cost over $1k (ouch) and that's out of my league for rods.

[JDM_1990_S13]

i guess more and more i am getting convinced to just get the rods re-shotpeened, hardened, beam polished and heat treated and whatever else they can do to them to make them sronger/better.

and at 1k for rods i'll get GREX or JUN before carillo as they too have them in stock (in Japan hehe) with different rod ratios etc, but that means changing pistons.

what pistons are you using boost_boy? and do you have a Dyno of either of your cars?? will love to see it..

[boost_boy]

Quote »what pistons are you using boost_boy?[/quote] On the new engine, I'm using WISECO slugs ground to stock specs because my cylinder's walls were to sweet looking to start boring on.Quote »and do you have a Dyno of either of your cars?? [/quote] This Dyno is the one I was referring to with the T3/T04B and also is the one I wrecked while handing a Ferarri modena a beautiful shot of my *** before I got cut-off at over 160mph. Also, this run was @ 18psi in 4th gear!

[JDM_1990_S13]

nice dyno run, what engine management? what boost was that at? 18psi?? and were these stock rods too... what difference do you think the JE/wiseco pistons and T3/T04E would make to this senario? maybe 20-30 more HP at the same boost level..

i guess i'll find out as i'll be assembling and dynoing the engine inn the near future.

[JDM_1990_S13]

wow and after getting cut off at 160 i'm glad that you are alive..

[boost_boy]

Quote »wow and after getting cut off at 160 i'm glad that you are alive..[/quote] I don't wish an event like that upon my worst enemy! I can only fathom what Dale Earnhardt (may god rest his soul) experienced when he hit that wall at that rate of speed. I hit a wooden pole after sliding over 60yds on pavement and over 60yds on grass and still destroyed my car really bad.

[JDM_1990_S13]

as we would say here in trini, "JAH BLESS!!!"

[boost_boy]

Quote »what engine management?[/quote] I used the SDS EM3-4F. Quote »what boost was that at?[/quote] 18PSI is correct!Quote »difference do you think the JE/wiseco pistons and T3/T04E would make to this senario?[/quote] Possibly increased TQ values as well Hp and with the addition of the more efficient turbos, 20-30hp sounds about right. The pistons expansion rate will probably be the key to better torque. My cars all ran about 146 degress Fahrenheit so they never really get up to normal operating temperature. So many factors will make or break the type of power you make. I mean, you got someone with skill tuning your Electromotive system, my system is tuned off my knowledge of the engine and just plain 'ol doing the math! I also had help from my friends at B.Y.P racing who basically set up a base-operating formula for me! Here's another dyno with the rpm model and which this run was done at 15psi of boost. the biggest problem i had on the dyno was the ghetto camaro spark plug wires I was using and they were causing the engine to miss and screw up the #'s. This was recorded in 3rd gear.

[boost_boy]

Here's wha my car did in 4th gear at 15psi and that Ferarri wondered why a crappy 'ol sentra was out muscling him. This MPH is attained at or around 6800rpm in 4th gear and I normally wind 4th gear to about 8k rpm. 299.8hp and 246ft/lbs of TQ, but look at the big gap on the dyno chart. This car missed every time I would take it up past 6500rpm.

[JDM_1990_S13]

really nice dyno runs, i have chosen to switch to a haltech E6K (hopefully this week) someone has one wired up for a CA18 RWD already using some stock sensors and plugging into the dash harness etc.. so we'll see how that goes.

would like to see the rpm's on the second dyno run before 6000rpm, see how the boost was comming in.. and aslo what injectors and air/fuel ratio were you tuning at? 12:1 or so??

[boost_boy]

Quote »what injectors and air/fuel ratio were you tuning at? 12:1 or so??[/quote] On that particular car I was using the MSD 50lb/hr injectors and as far as the specs on A/F ratio, I don't have them. But the guy who owns the shop and run the dyno said two things, that the misses from the bad spark plug wires is killing the peak #s because the dyno only records up until the miss (peak power) then it has to try and start over where it catches back on at and do not record the remainder of the run. 2nd that my A/F ratio says that the engine was running rich and I explained to him that's the way I want due to the fact that I run the car very hard at W.O.T. and don't want to risk leaning it out on the top end because it will be disasterous. Maybe in a couple of weeks when I put the old engine into the new car and set everything back up, I'll take it back to the dyno for tuning and not for Hp and MPH runs.

[JDM_1990_S13]

ok let us know what happens, i too ma going to be tuning very conservative about 12:1 (~.9 volts on the oxygen sensor) for the same kinda hing, i'll be using 550 injectors for now but i think i'll have to upgrade to 660's eventually..

[boost_boy]

$1,000 for rods??? they are smoking something most wicked. i had just had to go back a bit about those rods, but I'll keep everyone posted on how the car does. I have to wait till the computer and hand-held come back from SDS because the programmer got damaged when I hit.

[Movingviolation240]

I'm spinning my stock rods to 9,000rpm @ 22psi and havn't hurt them yet. All I did was beampolish and shotpein them.

Paul

[dan240]

paul, i thought you had oversized pistons? did the oversized pistons fit on the stock rods?!?!
