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.

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.

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.

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

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.

Good advice on both of the last posts.
