Motor rebuild
 

How can I find out about a rebuild, on a motor to put out about 500 horsepower, and the cost to send it out and have it done?

Re: Motor rebuild
 

I would say somewheres around $7,000-$9,000 for everything thats at the minimum.

Re: Motor rebuild
 

First if your not going to rebuild the motor yourself, I would find a reputable mechanic and a good machine shop.

Re: Motor rebuild
 

Why do you want to rebuild the motor? Nash put down 531 whp on a stock bottom end!

It also shouldn't be anywhere near $7k. All you need is a rebuild, Wiseco's and Eagle rods. You should be able to get that done for ~$3k. You are looking at another $1k if you get a stage 2 head done, but it isn't necessary for that power level, but it will gain you a little power.

Re: Motor rebuild
 

I think getting a 2.4 strocker or something would be nice for 5 g's or so.. you'd push well over 600 hp if you get a huge turbo w/ supporting mods.

Re: Motor rebuild
 

What year is your car? Do you want 500hp at the flywheel or at the wheels? The stock 6-bolt motors will handle 500hp at the wheels.

Re: Motor rebuild
 

Mike's car is a 1GA Auto GSX from what I recall. He is swapping in a manual transmission from a '93 Laser.

Re: Motor rebuild
 

Average cost to have a shortblock built with Eagles and Wiseco, balanced and all machine work done with a torque plate has been around 3K Figure another 1K for a decent porting job and assembling the long block, another 700 for cams and springs and about 230 for timing belt components. I just shipped a 2.3 to Tennesee and it ran $97 and took 2 Days. Those are the average costs for pretty much the minimum I will work with. There are a lot of options that can effect the price pretty drastically depending on how far you want to go, longer rods, knife edged crank, crower instead of eagle etc. Hope that helps.

Jacek is helping me out alot, but i want to gain 500 horsepower and I want to get this car on the road again and have the power I want. I have a 92' Eclipse GSX automatic swapping to a 5 speed. Thank you guys for all your help and if you can tell me more about getting the horsepower without sending the motor out that would be great. Thank you. I want wheel horsepower.

Re: Motor rebuild
 

Just bolt on the right turbo, intake/exhaust combo, plus some fuel upgrades and you'll be there without taking out the engine. I wouldn't redo your motor unless you don't want to mess with it again or you're starting with compression that's out of spec.

Re: Motor rebuild
 

Thank you very much. So I can gain 500 horsepower with out sending the motor out?

Re: Motor rebuild
 

The right way to say it would be your stock block (depending on condition) can support 500 horse. Not really considered "gain"

Re: Motor rebuild
 

If it ain't broke, don't fix it. There's something to be said for keeping your engine a "virgin".

Re: Motor rebuild
 

definately agree

Re: Motor rebuild
 

It is certainly cheaper. Considering his goals, it would be the way to go for sure.

Re: Motor rebuild
 

There are many other advantages to building a bottom end. Not just the fact that it can handle an X amount of HP. You can make it safer to rev, larger bore, obviously strength capacity. My .02 would be to get all of the mods you need to hit 500+ whp, then build your engine in such a way that it would help fit your specific needs. Mike ( at QPR, raptor) can give you quality top notch work for completitve pricing. Even though I dont PLAN to break 500 WHP, Im still going to get my block built because I will likely always want more.

Re: Motor rebuild
 

just get your basic bolt on's for now...turbo, fuel pump, injectors, MBC, cams, intercooler, etc...and build a motor on the side, take your time with it. Better to be safe than sorry, and when you finally do get your built block/head done, then swap them out and keep the stock motor as a spare, just in case, or sell it...either way :)

Re: Motor rebuild
 

500 whp is WAY more than most people realize. Do your other mods first and start enjoying them. Once you get in the upper 400's, then start thinking about building an engine. Why not take the $3k you would spend on an engine and get a turbo, FMIC, SAFC, fuel pump and injectors? You could have a 12 sec car on pump gas, which is enough to keep most people happy for a bit.

Re: Motor rebuild
 

Everything thinks they need a 600+whp car now though and alot think all they need is some stupid big turbo and it's done. I would do as JET suggested and buy the other bolt-on parts first, enjoy the car a little bit and get used to the power. It isn't going to be as much fun if you either A) try to build some crazy car right away for the first time and then never end up finishing it or B) actually get it done and built and go right to the constantly breaking one thing or another stage.

Re: Motor rebuild
 

Good advice on both of the last posts.

Re: Motor rebuild
 

What the hell is a strocker?

Re: Motor rebuild
 

Jacek told me to rebuild the motor so it would last there is alot of miles on the motor, and who knows how much more it would give me. I could just bolt on the add ons, but what if I blew it up right away. I want it to be done the right way, so I dont have to worry about breaking anything, or wonder if I get on it to hard that it might blow up. It is all a safety deal. If I spend that much money on add ons and have it blow up where am I then. I am sorry if I sound like a dick, I am not trying to. Don't you guys just love how much horsepower these cars can put out. I just love that you can build a 4 cyclinder car to run and beat bigger motor cars, and that you can get that much horsepower out of them.

Re: Motor rebuild
 

It really depends on your goals, if you are likely to keep wanting to mod the car, I would start with a good foundation (longblock) and go from there. The points Steve brought up are good for the average DSMer, the factory shortblock is extremely strong as is, and for a car that is in the 400-500 range, should be adequate. Budget and realistic end goals are the main things that should be considered in a decision like this.

Re: Motor rebuild
 

Nash's engine has at least 130k on it, I think it is over 150k, but I am not sure. I wouldn't worry about the bottom end, how many miles are on the car? Do a compression test and see how that turns out. The older engines are looser and won't seize up as easily, just run 'er!

Re: Motor rebuild
 

I am sorry but what exactly is the difference between a long block and a short block? Sorry I am new with these cars and they give me the chills on what you can do to them. I have about 150k on the motor, and I dont know how to do a compression test. My goals may take awhile but I can do them if I want it bad enough. I think I need to be around you guys some more, so I can learn some of this stuff in depth. Jacek is a good friend and has helped me alot. Can you guys teach me more? I love these cars and want to learn more.

Re: Motor rebuild
 

A short block is just the lower end, a long block includes the head. It is going to take a long time to work up to 500 whp, just start with the basic mods and work your way up. You can get in the 12's pretty easily for under $1k. An exhaust, some porting, UICP, SAFC and a few other small things. Your clutch won't hold long at those levels, so plan on a clutch shortly after you do the basic's.

Re: Motor rebuild
 

So what can I all get done for a thousand dollars?

Re: Motor rebuild
 

I thought andy's bottom end was out of patric's old car, that was rebuilt by shidley with 2G pistons etc. Not that it matters, just seemed to be what I remember.

Re: Motor rebuild
 

Yeah, I guess that was the old one that had all the miles on it. The one he ran an 11.2 on. He made 426 whp on that one if I remember right.

Mods for $1k, you will need a UICP, K&N, boost controller and exhaust. That should net you low 13's on pump gas with a slightly lightened car, throw in some race gas and you should see a high 12. To do it more safely you should have a 2g MAF, injectors and SAFC also. Throw on a DP and some turbo & O2 housing porting and you will be solidly into the 12's on pump, but the clutch will probably be toast from all the extra power, so throw that in there too.

Spend $120 and throw on a boost controller (set at 15 psi), boost guage, and K&N. You will be amazed and the mod'ing madness will begin :D

Re: Motor rebuild
 

I believe you are correct if I'm remembering correctly.

Re: Motor rebuild
 

Mikey you're in about the same boat I have been in for sometime. However, I am only looking to attain a wheel horsepower level of 350-400 hp. Check out this thread for some more discussion about what I've like to eventually be running for a powertrain and drivetrain configuration: http://www.dsmstyle.com/forums/showt...5&page=1&pp=30

Hopefully by reading through that thread some of your questions will be answered although you will probably come up with some more questions, but that's all good! :)

Re: Motor rebuild
 

So what can I get done with 1k?

Re: Motor rebuild
 

It's was just answered above, but there a alot of differant things to consider. Do you want to pay top dollar for parts (will chop the budget up quick) or try for some "cheaper" options. Alot of the choices you are going to have to make.

But I would do:
Intake, Exhaust, Better clutch to put the power down, MBC, gauges, AFC. And right there in most cases goes 1K out the wallet.

Re: Motor rebuild
 

Wolhfman's project is a very long term project and wants to be able to drive the car every day. The car won't be on the road for a while. His engine is leaky and is possible that it has worn valve guides. So I suggested for him to rebuild the engine and start out with that. He his target goal right now is to be 450-500 and with a strong longbock if later down the road he wants more power as a goal, that step would be out of the way once he is use to the power and learns a lot more.
