What to expect from a built motor

STeeL25T · #1 06-23-2009, 07:11 AM

Another "what if?" thread. I'm sorry, I know were all tired of question like these.

I know a couple of you have built up your motors with forged internals, delta cams, etc... I just wanted to know what you think your motor is capable of in terms of horse power?

I still don't know what all I'm doing to my motor. Its getting 8.5:1 piston and eagle rods, cometic head gaskets, outlaw spacers, ACL or Lan's bearings I don't know yet, and ARP bolts if I can track them down. I'm not touching th headers, I have no idea what to do with the heads (what did you do?).

I just want to know how much power the a motor built like that (or better with your suggestions) can handle. I don't think 450 hp would be out of the question, but then again how the heck would I know, so I ask you

Do you plan to go Turbo or S/C?

What to expect?

Well, lets see. Expect an empty bank account, headaches during tuning, power levels about 10 to 15 percent less then what you were hoping, a busted driveline, and possibly at least one blown motor.

I may be a little optomistic there. It may not come out that good.

Mike, do you think this is related to the internals you are using? I mean in my book, if someone wants to do such a project, he shouldn't sacrifice anything in going full fledge with this.

The bank account thing, you are 100% right. But to think that you "need" X parts and don't need V, W, Y, Z parts... here is the mistake.

Either get a mortgage

and buy the "additional" parts such as sleeves, studs, new fabbed cams, valves.......... or don't do it at all...

Nobody knows... as nobody has pushed a built motor... to its limits... yet...

Today with the help of HydraEMS and many other new modifications that have been developed... we have way more possibilities.

I am hoping to reach something respectable with my project... but who knows it is as likely to be disappointing as it is successful... at the end of the day you are wasting a significant amount money into a car thats not easy to modify or do anything with.... during a tough economic time...

not mentioning time and many other factors.

Planning what you want... how you want it and how you are going to get there... is key for any such project.

My setup will be single turbo, WRX 5 speed with Legacy GT 1-2 gear swap keeping the final drive. Hopefully that wont shatter like glass I can't spring for anything better than that. Do you think running it in front wheel drive mode with the fuse in would put less stress on launching?

I like the Hydra but I want to bypass it if I can for the time being, it just costs too much. I understand this isn't a cheap game, and I'm no stranger to dumping thousands of dollars into crazy swaps, but I'm just don't want to spring for it right up front when I have so many other things to pay for, then when it done I still wont be able to drive it for waiting for the stand alone and sensors and maps and dyno tuning.

If thats the case then I guess I'd be at he mercy of the MAF, whatever the Z32 one tops out at I guess.

I know you know what your talking about Mike but I'm hoping to avoid some of that... Heres to hoping

I have never built a motor before so I'm not sure what to expect. It seems logical that once its built then its just a matter of how big of a snail I slap on it, but of course its never that easy.

I haven't assembled the built motor yet. Ran out of funds getting the parts. I still need the heads and crank worked, and the studs. I've got a stack of boxes in my garage that are full of parts. I was just making a general observation of tuner experiences. Not specifically our cars.

When I said at least twice 8-10 I was meaning to say "at least 16", sorry for the confusing. 20 to 25 lbs sounds good to me, it all depends I guess. I can bolt a turbo to it that can do it, the whole thread was mainly can the build motor stomach it and can I tune it though lol

I understand... even gathering the smallest cheapest stuff can drain your pocket.

What will you do with the crank?
