i did my research like everyday still i dont find any help

so i have an ls motor wit lik 140K miles
getting ready to turbo it but ii needa get the motor rebuilt first which i dont kno much about
i know alot about the turbo part
my goal is about 220-230hp dd
wat do i needa do just so motor wont blow and stuff? like get motor sleeved,port and polished or wat?
im trying to stay stock pistons and etc

a stock engine will handle those numbers easily with a good tune. If you don't feel comfortable running boost on the engine that's in the car a stock rebuild would be fine, but you might want to consider some forged pistons and eagle rods to have more potential later on down the road(almost everyone craves more boost down the road) but in general the stock engine will handle those numbers no problem.

I would recommend rebuilding the engine before you proceed with your project! Would you rather do it now or after it blows up, your call!
While an OEM rebuild would be sufficient you may want to look into pistons, rods, bearings and head studs to complete the build. Your power goals are not high at all but with 140k on the clock, it COULD be a ticking time bomb without a rebuild.

My ls motor has approx. 150k miles. Stock internals with arp headstuds. I daily drive it and it makes 300whp. Search for the Ls-t forum here and you will find a lot of similar builds. Just get a good tuner.

mykulangot92

yes forsure im gonna get it tuned as well
the thing is i have the money for turbo,ecu,injectors etc but i need more for the engine part so im guessing i have to rebuild the bottom end
wat do i do? replace everything? port polish? sleeved? i still dont know
i want to spend only about $1500 on the motor preparing

mykulangot92

yes i prabably will crave more boost but i think ill fully build it or swap it by then

You don't have to rebuild the bottom end. If you have money to blow then build a motor so you can turn the boost up. Your goal is easily attainable with the stock motor.

i'd say then get a leak down and compression check to see the condition of your engine. If everything comes back good your car would be healthy enough to boost. In that case i'd leave your engine stock and run it that way and spend that money on the new engine you planned on building when you wanted more power.

You could pick up a stock ls motor for cheap, the heads are fine for the type of horsepower your looking to make, the sleeves are durable to, the most common things people swap in a setup like yours (200-350whp) for are arp head studs, pistons and rods which price wise would fit in your budget range.

If you wanted more power than that, then that's when things start to become more expensive, but to keep it simple get your car checked, if it passes boost it and be happy.

Not even the best tuner in this world can tune WORN parts.

With over 100k miles, i would strongly suggest a rebuild. Whether it be stock or forged pistons/rods/etc. I think its due.

Hell, i wouldnt turbo my car without running a compression test to make sure everything is up to par. Now add, 150k miles on that, thats equivalent of 15 years of driving (given 10k per year)...

I suggest you start looking into engine builders before turbo installers and tuners.

Budget and turbo should never be used in the same sentence. They dont go hand in hand. You might create a budget now, but it will eventually cause for you to shell out more money for 1. things that need upgrading 2. things that fail 3. retunes....etc

cheap, fast, reliable.

That is a common statement used and im pretty sure you have heard about it before.

BTW, you can only pick 2 of the 3.

Listen to him. Honestly.

You should never be thinking "hey, let me turbo it NOW, and worry about the motor LATER"

What we are trying to accomplish here is to not undo and redo what has been done already. No need to do things backwards either. First, you build. Then you boost. If you dont have money for it now, save up, and spend it wisely.

Sleeved and P&P are not even something to consider with your HP goals.

OEM cast piston ringlands melt like butter and rods (and rod bolts) aren't very strong. What I'm saying is don't rev it to the moon and back and get yourself a good tuner. If you do that on a healthy stock motor, your HP goals can easily be done safely.

It seems to me your not sure yet what your really looking for out of your build. I'd say go big or go home. Reason I say that is when you cheap out now, it comes back to get you later on down the road IMO.

im just gonna go big now
i got money for the whole turbo thing but now i need the motor rebuild wit forged parts

mykulangot92

how much does it cost for rebuild? with out pistons, rods and etc..and with?

1998GsRIntegra

www.acuraoemparts.com for all oem parts if you plan to do an oem rebuild.

You need: rod bearings, crankshaft bearings, thrust washers, piston rings, all block gaskets, water pump, oil pump, intake and exhaust valves, valve seals, valve guides, valve springs and retainers(they ware over time), keepers, all head related gaskets, head gasket(itself), ect.

If you plan to build the block, you need evey thing above, excluding: piston rings. They will come with the pistons and rods you buy.

I'm sure I'm forgetting things, but this gives you a general idea if you want to do it right.(excluding actually building it) thats a whole nother post.
