Ld9 Rebuild

[AnderbrA]

Almost complete: ordered pistons today. will be here by next friday.

Heres what I am doing.

Rebuilding with all forged internals.

Wiseco Forged Pistons .020 overbored, 9:1 compression
Eagle Rods
Clevite 77 bearings
2.4 "Secret Cam Swap"
Port and Polish Head
Pistons, rods, crank...balanced.

Then guess whats comin?

psssssssssshhhhhhhtttt

So far here is my spendings list.

475 for Pistons
325 for Rods
150 for Cams
Still Awaiting Labor, but it should be 600 or less.

Total for a motor capable of holding a good 15psi+:

$1550

that is freakin sweet man!!!

where did ya get the cams? i'm lookin to maybe go that way, but don't know if cams alone are really worth it

Pictures?

[AnderbrA]

I got the cams through car-part.com or carparts.com whatever....i found them at a salvage lot in IL.

was gonna order from 2 different salvage lots, but the second one had both cams so i just ordered both there and got combined shipping....

always the bargain shopper

the motor is at the machine shop, I will take pictures when it is done. Although it will look just like a normal motor, since everything that changes is on the inside....lol

[AnderbrA]

oh, and i forgot, next door to the shop is an exhaust shop.....to prepare for the hairdryer i was thinking of running a new headerback exhaust.....

I was thinking straight 3" back to rear suspension, then fork it to duals on each side2.5"....because 3" would be hard to get over the rear suspension....

fairly inexpensive too....$4 per foot and $3 per bend. install would be like 30 bucks.

[AnderbrA]

actually you can get decent gains from the cams.....depending on mods, you could get up to 15-20 hp.

[j-work]

Sweet AnderbrA! Post some pictures when you have a chance. So, how much of an hp increase are you looking at without the pssshhhttt? 30 hp?

[AnderbrA]

Yeah I am hoping for 170-180 hp when its all done....i dont know for sure, but thats what im hopin for.

I know without doing any rebuild i could get 230 with 10psi!! so im hoping for around 250 @ 10psi.

awesome, keep us updated!!

[Oldsman]

some good choices. good luck

nice build up what size turbo are you running and what are you using for fuel management?

[Fast Eddie]

Nice work be sure to have the cams checked to make sure they are in spec. cams will wear so be sure they are in good shape.

How did you drop compression ratio AND over bore ?? (Stock CR is 9.5:1) did you have the whole assembly balanced or just the inidvidual pieces? if so how fast did they spin the assembly?

If all you are adding, prior to boost, is the serect cams then based on your specs you will probably make ~160-165Hp@ the flywheel. You are dropping compression remember. the internals might be a bit lighter so you might hit 170HP but with just SC swap you are not gonna see 30HP gain, sorry. Remember the compression drop is gonna cost power.

Also what is involved in the PnP, that can make a diff, esp if they do valve work. If you have the time drop me the spec in a PM, you are definatly doing somethings I would like to know more about.

Please please tell me you're having the head ported...

It's very restrictive with boost you'll see a large bump in power if you get a decent port job done...

Also the stock throttle body is 52mm.. with boost, again, the bigger the better, so look around for a 60 or 62mm one.

That is going to be very nice. I assume you already have 2.3 intake manifold and TB?

Eddie, thats sounds about right when its all said and done, I was looking at the 170 range. The Wiseco Pistons come in a 9:1 compression Ratio, unless you request otherwise. The balancing im not sure, the crank is getting ground into spec, I dont know if they balance the whole thing or just the individual parts....i will find out.

As far as the head. The shop does a valve job and smooths things out, but the guy who is actually tearin my motor apart does some PNP work, so I am gonna have him do that.

I ordered my pistons from Karo at CarCustoms, and they were shipped today, so I will have them by the end of the week. I am hoping that It will be done in 2 weeks.

Also, as soon as its done, I am going next door to get a full exhaust.....I was thinking 3" from header back to rear suspension and then split it off and run dual 2.5" to each side.

Good Idea or should i stick with 2.5 the whole way?

T3/T4 Hybrid. probably a .57 trim or Super 60.

Most likely for the time being.... larger injectors and Vortec FMU....as i increase boost, ill have to revisit that. I am still researching it.

any ideas?

no, soon.

Depending on how much boost you're running, 3" should be good- maybe a little much for everyday driving, but it'll be able to handle it when you crank it up. Sounds like one beast of a LD9. I'm not terribly far from you, I'm just outside of Minneapolis- do you ever head this way?

[AnderbrA]

quite honestly ive been to MN like a handful of times...lol

Well you should let me know the next time you're in the area, I'd love to see the car.
