400+hp

[mistamacadamian]

Who here is making 400+ ? I know a couple people are pushing it on the 2871 which I was planning to do but i got a good *** deal on a 60-1. Any one running something bigger than a 2871 and have a build thread/pics/dyno numbers/times/pics??? I got a fully built head and stock bottom which i would plan to go with and just add race gas to get 450 out when at the track and 350+ daily. Ive searched alot on here on here but come up with little things here and there but no follow ups on anything.

[Koshin]

Ive only ridden in one SR with a 60-1, and to be truthful I didnt like the guys setup....wasnt to thought out. The 60-1 just seemed to spool way to late, he ran out of revs before the turbo was even breaking a sweat. I am partial to a quick spooling turbo personally, that being said it hit hard but just to much lag on that particular setup. I think with the right head you could make a kick *** 60-1 setup. Are you running the stock head?? Just my experience....

I actually just saw in your sig that you have a built head, you might be good to go. Only one way to find out

[DrifterProdigy85]

400whp isnt hard to achieve. Especially with a 60-1. Thats definitly a large turbo more meant for 500whp. Just need the essentials of 260 or 270 cams, 740cc or 850cc injectors, Intake Manifold, and Decent Tuning. You should break 400whp with less than 18psi. Personally if your looking in the 400whp area, go with something smaller like a GT3071R. Fast spool and broad powerband using stock revs.

BC 264'S IN+EX/BC springs/BC retainers/BC intake and exhuast valves, cometic HG, ARP Head Studs. My set up with this 60-1 would be 740's, custom top mount manifold, looking into ebay intake manifolds b.c it looks like the same ****, apexi power FC. On pump gas i know 400 is not problem. Lag I dont care. I have a friend with a z32 TT, he gets full spool at 4700 and revs to 7400 and yea its laggy but it pulls hard. So if i get full boost at 4500, i wouldnt care b/c id be revving to 8. Nice power band. I see some people here and there at meets talking about mid and high 400HP SR's on stock blocks but dont understand why theres not alot of info on them. I see the same with viedos on streetfire/youtube. Im pretty much aiming for 450 stock block.

60-1 would make over 400whp in it's sleep.

go on Zilvia, look up member Steve Shadows...IIRC he's got a 60-1 on there.

Sounds solid, aside from the BC parts and the Cometic gasket :

[mistamacadamian]

Ive heard mixed reviews on BC's but then again I have heard more good ones. Top mount should be done in 2weeks, its costing the piping plus 400 to be made. And what thread is good without pics? so heres a couple.Friends e36 caught on fire, something possibly the jack fell and shorted out the battery.And picture of the coupe.And pic of my 1st hatch

EDIT: codaynce...how does it feel to have a 240 with 400hp if that can be described?

With goals of 450+ with that 60-1, you should really look into the higher end cams and supertech valvetrain equipment. If you notice, all of the 450+ guys ues similar valvetrains, none of which have BC stuff. It's marginally better than OEM imo, but not the best or anything I'd ever use. I know I know, people will say "ALL HE LIKES IS JWT and or XXX", but if you notiec the trend of guys making big power (or reliable power), not many (if any) run BC crap.

400 whp in an S chassis tho? Extremly awesome. My car easily beats on new Z06's/997's on the circuit and street. However, my 400 whp is out of a t2 based snail, and I've got 4.60 gears in it...it's all brutal low end fun.

[mistamacadamian]

With the 60-1 im looking just to max out the stock block when running at the track, when head was removed it look in great shape. So with that in mind I thought 264's would be a good start. The head looks amazing, got to see it yesterday and should be on by monday. I picked that turbo up for 500 with less than 2000miles on it so if worst comes to worst, ill just go with a t3t04e. As for your z06 kills, thats actually what my friend was about run when he mis-shifted from 6k in 3rd to 2nd. I just gotta make sure to beat my sister, if you can belive if shes about to go with a SVT Cobra motor in a '06 V6 mustang body.

[DrifterProdigy85]

Doesnt sound like too hard of a thing to do. Stock SVT Cobra's trap in the 112mph area i think. My S13 at 400whp does 121mph. Cobra needs a larger charger to get that fast i believe. Id like to try my hand at a new Z06 in a drag race but none are around. All old people drive them here.

Depends who you talk to, as my buddy corey goes 10.80's @ 125 with his Slobra Suspension, tires, Level II axles. Stock 'heat'on, no port.

A FULL BOLT ON COBRA (exhaust, pully, tune etc etc) would be a good run for most 360ish whp s chassis cars.

New Z06's are downright nasty at the drag strip tho 0-60 in first gear helps get them out of the hole stupid fast.

[luv2spedup]

dude im running a 60-1 with a .48 back housing with hks 264 cams crower spring and retainers etc with a built bottom end and a greddy intake manifold.... i dynoed 333 rwhp and 311tq at 17lbs of boost , but i only could rev the motor upto 6200 rpm cause the car started breaking up on me(weak coil packs). if i could have reved it up to 8000 /8200 rpm(i could rev my motor upto 8500) i guess i could have seen a hp number upwards of mid to high 300rwhp.....hope this helps, and good luck with the car

[IMG][/IMG]

[DrifterProdigy85]

Do you have a dyno of that? Id just like to see the power delivery. I would think the .48 A/R Turbine Housing would hold you back on making much power past 7500rpm.

Weak coil packs?

Please

What plug gap are you at, and what are you using for a tune? Timing?

[mistamacadamian]

it helps alot, when do high HP sr's start to use MSD isgnition? im pretty sure that would be the problem with your revs, ill be goign with the hks twin power. AS for your exhuast housing mine has the .68 exhuast side. thats 2 inch piping on your hot side right? looks good though man im hoping to have this **** done in 2 months or so. theres actually a old guy who drives around my area at night with a cam'd z06, i told him im coming for him and he just laughed and down shifted lol. and as for svt cobras, i dont under estimate them. i was going to buy one actually and with simple mods like your friend has...yea that trap says enough.

I didn't notice any ignition problems at 20 psi at .022 plug gap

I still installed an XS Engineering Power Pack II though (similar to the HKS DLI)

[DrifterProdigy85]

Yea stock ignition system isnt really all that bad. I run stock coils and everything with NGK Iridium 8 plugs gapped down to .025". I run 22psi without a problem. Id still like to upgrade to the Splitfire Setup though.

[luv2spedup]

well i am running NGK iradiums 8 gapped to .25, and AEM ems covers the tunning i said weak coil packs cause a couple of month backs one of my coil pack went bad and i had to replace it with a spare one i had sitting around, i was thinking about going either with HKS spit fire or hks twin power dlithe piping on the hot side is actually 2.25i have the dyno sheet but i don't have a scanner to scan it but i will try to take a pic of it or some thing but before the coil pack issue the car pulled hard all the way thru 8k it never felt like the power band was dropping it kept going strong, even at the dyno i didnt go past 6500 cause the car srarted breakingbut i have to admit even with a small back housing it's a very laggy turbo it starts to spool after 4k

[inkslingers13]

what turbo mani are you running???^^^ looks like a ebay one? hows that working for you? sorry if im wrong

[luv2spedup]

it's actually a custom manifold..... and it's holding up pretty good. i had it made it by GSC motorsports

[driftfan420]

Why run HKS /DLI?instead of just running the LS1 coils. I thought they were direct fire. wouldn't that be more useful?

Last night i raced a guys SVT Cobra in a drop arms street race. He kept telling me it was stock but the charger wined pretty damn loud to not be running a smaller pulley. Overall the car ran good. We both spun like hell in 1st and i started to pull away in 2nd and kept pulling little by little in 3rd and 4th. It was a full 1/4 mile run and i was about 4 cars out on him by 120-125mph. A 400whp 240 can give a Bolton Cobra one hell of a run. Now i cant wait to get my T67 and 2 Step and run his Twin Turbo Cobra.

[mistamacadamian]

thats pretty impressive for sure. your running a 2871 right? i know your motor can handle alot more than 400, i wish i could build the motor then put this set up on but too much money at the moment.

[kentuckyslider]

Drifterprodigy85, I just joined nico today looking for some insight into getting more "useable power" out of my SR without running on the edge. We seem to have similar setups and I need some advice. I have had my S13 for about 9 months with this setup and want more. First off, I'm running a stock head and cams, stock intake, and throttle body. I have purchased a top speed intake and am debating on the 70mm tomie throttle body and adapter plate. Is it worth it??? Next, what cams would you recommend? I am also considering going to a gt3076 .63ar or a gt3071 with .86 ar with an internal gate. What cams, springs, and retainers would you get that will be flexible if I decided to upgrade to the bigger turbo? My 72lbs injectors aren't efficient past 450whp so just under that is my goal! I am setting this car up for drag racing and am considering a Labonte sport methanol kit WITH THE SAFTEY SETUP.

You'd need something to control them

Dig running the v8's is tough, namely due to our cars having horrible street launch manners. I've found me best RPM to be around 3300-3500 rpm making 4/5 psi of boost. Super low, but it works.

From a roll, I beat up on full bolt on Cobras.

1. Get JWT S4 cams (or HKS 264 step II's)2. Get a 3071r3. 72 lbers are MORE than enough for 450 whp4. Screw Internal gate, get a top mount and external gate.

Just a few questions........1. can I use BC springs and stock retainers with the HKS step II's?2. .64 or .86 ar on the 3071r3. Why no internal gate? Do you gain much if any power. It will be much cheaper to stay with the bottom mount.4. as for retuning, will I need to send my ECU back to JWT for reflash and let them know what I have changed before I spend any time/money on the dyno? I have SAFC and NGK wideband 02 but obviously I didn't tune the car and don't know much about it.

i dont think you run a bottom mount t3 flange, witch is what a 3071r is. top mount FTW

[kentuckyslider]

That is why I want this atp turbo http://www.atpturbo.com/Mercha...e=GRT or the gt3076 with internal gate http://www.atpturbo.com/Mercha...e=GRT

[mistamacadamian]

yea def go top mount buddy, tial 38mm is like 100 something used, custom top mount on that ho, 20 psi, and that 117 trap is gonna jump to the high 120's. just got my check from the IRS too so that 300 is toward my manifold, should be ready in about 2 weeks b/c i gotta put it on to make a new hot side to send out and get welded for free:) i can just taste 400hp on my tongue. but on the down side my head is taking way too long due to 5 lost shims which will be here tomorrow. then 5 lug swap, drag radials, track. any bets on times/trap?

[codyace]

ATP and other design houses have t2 versions of both.

1. can I use BC springs and stock retainers with the HKS step II's?

PRobably, but BC stuff sucks. Get Supertech. regardless, you'll need springs.

2. .64 or .86 ar on the 3071r

Hard to say, but with the topmount I'd look at the .86 to use the larger exhaust volume to your advantage

3. Why no internal gate? Do you gain much if any power. It will be much cheaper to stay with the bottom mount.

Internal gates are good for liek, 300 hp cars. Gratned some of us have had success with them, not many last for long. Preload, shorter rods, different brackets....BLAH. External gate modification is the way to go. Better control is key.

4. as for retuning, will I need to send my ECU back to JWT for reflash and let them know what I have changed before I spend any time/money on the dyno? I have SAFC and NGK wideband 02 but obviously I didn't tune the car and don't know much about it.

Throw the SAFC in the trash. Get the tune from JWT or Enthalpy, and you'll be good right out of the box. If you want more, just datalog a run or two, email JWT or enthalpy, and they'll mail you a rom chip to replace the one you have.

[kentuckyslider]

Thanx for the help. A couple more questions(probubly more).....1. Where can I get supertec springs? 2. What is up with the ebay intakes that look like greddy/top speed copies?3. Is the tomie 70mm throttle body worth $350 or should I just try to port match my stock TB with the new intake? I'm going to put the 264 cams, new intake, and retune and see where I'm at before I replace the turbo. I only have about 4k miles on the gt2871. I am also considering the labonte water/methanol kit. I no nothing about data loging, but I'm sure JWT can fill me in. I already have the HKS step II's on the way along with a freshly powder coated valve cover that will be going on with the cams. If you have any other suggestions let me know.
