Hey everyone just wanted to share my build so far with you guys and maybe get some input on my plans. My goal is to reach around 500-525whp. So far the only thing I have completely done is my bottom end. Here is what I have done

Darton Dry Sleeves Std Bore
wiseco 9:1 pistons
eagle rods
ACL bearings
New OEM oil pump
New OEM water pump
ARP head studs and rod bolts
cometic head gasket

I think that is it for my bottom end. As far as my head they only I have so far are Supertech Dual Valve springs. I plan on using all supertech valvetrain but with stock valves and Brian Crower stage 2 turbo cams.

As for fuel I want to use Injector Dynamics 1000cc with a walbro 255 and running e85 at all times because it is fairly easy to get here. Also Plan on using AEM fuel rail and also fuel pressure regulator.

As far as the turbo I am thinking either a 3076r or precision 5858. I was kinda weery on the 5858 because I didn't know how laggy it would be for my setup. I would like to have as much input as I can get. Im pretty confident with my setup and have done endless hours of research but I just like to ask around and get some first hand experience. Please let me know what ya think and have a great day!!

Just started looking at the precision 5558 thinking I might go with that. Good idea or no??

If you are planning on running crower cams in that head you need to upgrade to vtec water pump and timing belt from gsr otherwise the coolant will cavitate and cause false overheating. The precision uni will make nice power. I run a 6266 and love it but others dont like precision. You cant beat a gtxr turbo though but your gonna pay through the nose for it

You'll be pushing those turbos to make over 500.

My buddy just finished putting together his LS build with a 5858, so should have results soon.

What fuel do you plan on running? I would not play with 93 past 450whp.

hardcore97

a 255 and 1000's will be close for e85 and 500 hp. i would go a little bigger on the injectors to give you some more room. i have also seen several builds use the 404 cams rather than the stage 2 turbo cams and make great power even though they arer marketed as an NA cam.

Im going to be running e85 and was thinking about selling my walbro 255 and going with the aeromotive 340. Yea I was thinking 1000cc injectors would be almost maxed out. Im probably going to go with 1250's. Im thinking the 5858 is the way im going to go .63ar. 404 cams would be better for my build you think?? LightningTeg if you could let me know what he hits and aslo his setup that would be awesome. Just a question but is the vtech water pump really going to make a difference?? If so I will try and sell mine and pick one up I just didn't think it was that much of a difference. Thanks a lot guys you have all been very helpful. Im trying to get everything squared away for this winter.

LightningTeg

I think their are better options now then the 340. The Walbro 400 (E85 version) for example.

Yes, 404s will do better. Thats what i have been running and they make great power.

His build is pretty much identical to mine, except I have a sleeved block:

81.5 B18B
CP 9:1 pistons
Eagle rods
ACL bearings
ARP head studs

PR4 head
Crower springs/retainers
Crower 404 cams
Victor-X manifold
ID1000's, 93 Oct.

Tubular log manifold
PTE 5858

Personally I'd go with the Garrett unit. Much better track record and will give you gobs of midrange power and torque

IM going to upgrade from my 255 and use the 340. I think I might try the BC 404's like LightingTeg suggested. Im still held up on the turbo tho. I would like to buy the Garrett but I think I can make just as much on a precision im just worried on the lag. I was looking at the 5862 by precision and am kind of leaning that way now lol. I want to make around 500-525 without it being hella laggy. Anyone have any experience with the 5862?? If not I might just be the guinea pig.

wantboost

5862 has an awfully large turbine wheel for such a small compressor wheel

If you're worried about lag you just went in the deep end of the pool... you don't need the 62 turbine side to make your power goals. You'll just end up with an overly laggy setup that has very little midrange power and torque

Do you think my first choice of the PRE 5858 would be the best for my power goals and setup without being very laggy??

jarrodsi

iTrader: (2)

PTE I meant.

jarrodsi

iTrader: (2)

You think a 6262 would be too big??

Turbo-LS

iTrader: (4)

6262 spools really well for its size. I love my 6266. 6262 with a .63 housing will get you 500-550 27-30 pounds boost with the turbo cams

jarrodsi

iTrader: (2)

6262 won't be too laggy for my standard bore you don't think??

TheShodan

iTrader: (14)

Absolutely it will.... racing life will suck from 3000-5800rpms of rev range.

wantboost

iTrader: (2)

I could out pedal you on my bmx bike until you made full boost lol

jarrodsi

iTrader: (2)

Lol i hope i can beat a pedal bike haha. I think I'm going to with the 5858. Will i get close to my power goal with this turbo?? I plan on getting the .63ar

TheShodan

iTrader: (14)

really pushing it with that turbo for 525whp.. About 25psi or so on average. Stick with a Garrett to do that.

Turbo-LS

iTrader: (4)

Really guys you just don't like precision turbos my turbo 6266 isn't Laggy till 5800 rpm. Don't lie be honest then drake your reasoning for choosing a Garrett turbo not jay make others look worse then they are

My 6266 spooled just fine stock bore 9:1 compression.

TheShodan

And I'm simply saying that your definition of "not being laggy" is really subjective. I don't care what company it is. Having that large a turbo like that is just not responsive at all. period. It could be Precision, Turbonetics, FP, or even one of MY designs. I'd NEVER put anyone in anything that big for that purpose for that power level.

If yours is working for you, fantastic. But to boast that it isn't laggy until 5800rpms is not anything to be that proud of when a Geo Metro can out accelerate you the first 1000 yards, before you'd catch up and pass him, with only 2000rpms of range to deal with. Sorry, but that's just not impressive, when it can be done more efficiently with a better match.. Regardless of company chosen.

This isn't "hate" (at least on my end). this is about matching the right turbocharger combination for the need.

I'm not saying he needs to be running a 6262 just saying it isn't as laggy as its being represented is all.

TheShodan

We'll have to just agree to disagree on that. 2000rpms or usable rev range vs. over 4000-5000rpms with something reasonably smaller. Let the OP be the judge.

I disagree with precisions business practices. That's all. Plus they have a very high failure rate for the volume they produce... that says something
