Engine Upgrade Question

I've noticed that in general everyone on the site talks about the same basic upgrades. They are all really cool and really good but I haven't heard of anyone really trying to upgrade the engine itself.

It's awsome to put the TT gauge, JoeMBC, CAI and a lot of cool little things on it. But then most people only boost to like 9 psi (with the new pcm fix) because the engine cannot handle any more boost without dammage.

Anyone tried to make the engine capable of some serious power. Somewhere from 1-2 bar like the WRX, EVO etc. With a new huge turbo/intercooler, new pistons, new lube system, upgraded valvetrain, all that good stuff. If you do all that and put 20 psi in this car it should hall so much ass but still look and handle like a dream.

Has anyone looked into this option yet?
 
There are a few members with built up engines (forged internals). It is extreamly exspensive, on top of all the engine expenses you will also need fuel and igniton control.

It is not cheap.
 
Some of the MP3 guys have bullet proofed the internals, I doubt any MSP guys have.

The problem is, you do all that, and start nuking trannys and drive shafts, cause they cant handle that power.
 
it's all about money. if you've got the money, you can do whatever you want. including making one fast ass msp :D i think i need to start playing the lottery.....
 
Yeah I was a little afraid of the cost, but I didn't know so i asked.

I would also masively upgrade the tranny to contain all the power. I've seen 600 hp clutches out there so I know it is possible.
 
What do you mean by bulletproof the internals? Is that just slang or is there some way of protecting the parts.

Also on all the forged parts do you have made the same size and specs of the previous parts, or is it done to the parts that you already have?
 
bulletproofing is slang for replacing the internals with stronger parts. the parts that you replace are usually forged and are of the same size and specs of the previous but they can take much more abuse. though there are many kits out there that have bigger pistons in case you bore out your cylinders or increase the displacement (stroker kit). they're expensive though....very expensive. but if you get the major parts replaced (pistons, rods, bolts), you should be able to up the boost with no problem.

of course, that's just the bottom end of the engine. you still have to worry about the top end.....your cams, camshafts, valvesprings, retainers, etc. but seriously, since we have an iron block (rather than a weaker aluminum block as most cars have), if you replace the pistons and rods, you'll be good for a long while.
 
slap a big turbo on it and blow it up like im a gonna do once i get my car back! been seen many times but wanted to show the newer members:p

I think, when you first heard of an engine be made "bulletproof" , i think you misunderstood an engine thats being built of BILLET internals. billet (i think a type alum) is a very light wight material and is used mostly and racing application and should not be used in street use, the lighter mass from those parts is not worth the risk(they do brake often).

when people build engines they normally use forged parts. do to strength and cost, especially in an engine built with a turbo. My other car has pistons made of some type of powder metal fused together and that engine is rated for 450 HP not sure on tq

and who says a iron block is weaker then alum? it all depends on the design of the block and its use, with modern tec alum blocks are about even with iron (hell they can make a block out of ceramic) it all boils down to how much the top dog wants to make per a car
 
I am guessing your new to the forum. Im glad some others are thinking of doing the same upgrades. I have an '02 protege 5. With forged aluminum pistons and forged steel rods. I've run consistenly on the street 10-12 psi. (Because she is an ever day driver) I have run her many times at over 18-19 psi. NEVER had any problems with the tranny or the axles. As a matter of fact the stock clutch is still in use. It really boils down to how you drive. i have seen 16,000$ quaiffe setups blow up at the track because of abuse and idiotic launch habits.
To answer some of your questions the internals can be had to whatever specs you want. They are a custom application 90% of the time. Unless they have something on the shelf( which the majority of the manufacturers do not for the MAZDA)
Since i am not in the automotive world any more it has been difficult to get away from the family business to have some fun at the track or even dyno. Hopefully i will go with some friends in a couple of weeks here to englishtown and she what she can do.
