Cosworth Crate

[LamboFoFo]

So has anyone on here ever bought one of these?
Iv been looking in to them for when I get back and start on my focus.

I wanna put in a 2.3 and i figured if i bought a stock 2.3 and built it, it wouldn't be a whole lot cheaper then the lowest end 2.3L Cosworth.

Base plan: Get the Cosworth 2.3L 220bhp@7200rpm (20002725) Get a Custom build MTX75 with stronger gears upgraded clutch and Quafie LSD.

After that and after i rebuild up some more money I would like to pull my interior build a custom aluminum dash. Do a Pectel ECU and Pi Omega D1 Display.

Might look into a FocusSport Turbo last of all...

If you have any info on the Cosworth Crates please tell me what you know.

Thanks,
Dusitn

No one knows anything?

It's Cosworth, nuff said.

What really matters is what your goals are. It may or may not be the right solution for your needs.

Well honnestly from what Ive looked into it seems that all the crate engines come with barrel throttle boddies which means that you would most likely have to swich over to a Cosworth PCM and harness because your prob gonna be running speed density (different way of programing fuel trims) insted of using a MAF. Which is gonna mean more money on to of your already 12 grand engine. And your Prob gonna have to take it to Cosworth for tunning, at a premium Im sure.

The other thing is your most likely not gonna have ac cuz the belt pattern is different from the Ford Duratecs. Without some major Mods.

Also that 220 at the crank and Im sure at only 9:1 compression its more like 170 to the wheels tops.

So with already prob a 15 grand price tag my question is why? With 15 grand you could build a 300hp boosted vehicle with some Cosworth parts and have alot more smile factor. All with ac stereo and what ever else you desire.

Not trying to do any dream stealing just trying to display the details. I have a buddy that had a high compression Cosworth crate and he ended up selling it cuz tuning was a nightmare and the vehicle was barely streetable.

I would give that 15k to Randy at FSwerks and let him build you a ultimate track car 300+hp and nice suspension setup.

Yea ill prolly go a route liek that or just get a used 2.3 strip it downa dn build it myself

[locdowg7]

Thats the most rewarding way.

The other thing to consider is that you mentioned buying a high strung naturally aspirated engine and then possibly adding on a turbocharger later on. If that's your end goal you probably need to plan for that from the start. Certain components like high compression and lightweight rotating assembly pieces may be good for a high revving, naturally aspirated engine but be poor choices for a forced induction application. If you're dropping that kind of money you wouldn't want to be going back into the engine and replacing everything.

[UnFocusedZX4]

If your going with the turbo setup make sure you buy/build and engine with low compression.

[tallguy2.3]

What purpose will the car serve is my biggest question.

[LamboFoFo]

yes i know about the parts and compression if i was going to spend $15k motor you would think they could change rods and pistons for lower compresion.
yea i did more research and iv decided unless your sponsored a cossie crate isnt really for you. Ill pick up a 2.3 and build it myself ill know whats gone into it and feel more acomplished about it.

the car will be build for AutoX and Road Course

Then before you start spending money left and right, 1st thing to do is find out what sanctioning body (SCCA/NASA/etc) you are going to run with.
2nd buy a rule book and read it.
3rd build the car around the rule book.

You will hate to spend so much money and then find out a mod isn't allowed.

[tallguy2.3]

^Agreed. Just figure out what it has to do before you run out and start buying parts.

Looks like DoingAnything's car is pretty built for track-type conditions. Its serious enough to take on most competitors, but even that is relatively useless information if the car doesn't fit in the group or class that you want to drive it in.

[LamboFoFo]

I already Run SCCA. and Im would be in SM class.

[tallguy2.3]

Well there ya go. I really know nothing about classes in autorcross but you do so build it for that. A whole Cossie motor swap is just a huge ordeal in probably every way, so I'd avoid it.

[LamboFoFo]

Yea. the more research i do the more i just want to build my own motor. Its not hard to do just time consuming but the end result would be WAY better cause I would know that i built it and it will be purpose built for what i want it to do.

[warneej]

~200whp of high-compression for $15k seems a little ridiculous however the baller factor would always be there. You could build it yourself for half that price with a good tune.

Then attempting to put a turbo on that motor would require either a stupid amount of timing or race gas to avoid melting pistons and you still wouldn't have the power potential of a basically stock motor on boost.

The Cosworth deals are meant to be high-revving NA engines, don't even consider them if you want to boost later.

To reiterate what everyone else has said, plan first and mod after.

Any of your plans would be legal in SM as far as current rules go.

does anyone know what the break in time is for a 2.3 crate, or can u just start rippin on it right away?

Just like most any car your prolly gonna want to put atleast 600-1000 Miles on the car and then some Highway time at higher consitant RPMs.

There was a dude that picked up a brand new Cobalt SS and literally 20 min after pulling it off the lot blew the motor cause he romped it. Needless to say....he voided his waranty because of what the on-board computer told the dealership. Sucks for him it wont even make a nice yard ortinment

A new engine in most modern cars are broken in from the factory. Most manufacturers still recommend around a 500 mile break-in interval due to other driveline components benefiting from it. On the case of the Cobalt, I own one and can't recall reading of that particular incident on any of the forums, but there should be very little you could do outside of extreme abuse that should kill a new engine in that little mile. I'd bet there's more to the story and I'd bet there's a good chance some manufacturing defects were involved or something like a missed downshift into too low of a gear, etc. (i.e. operator abuse/error).

Engine break-in can be pretty controversial with a lot of differing opinions. It's not going to hurt to do a normal break-in for a few hundred miles but I'd suggest following what Cosworth recommends instead of asking for third-party opinions.

[UnFocusedZX4]

Speaking of breaking in an engine. My buddies STI only required 50 miles to finish setting the rings. That was it. As for building an engine then breaking it in you might want to go like 700 miles especially if you put a brand new exedy clutch in with the new engine.

[cpz1987]

build it yourself. be alot cheaper then putting a brand new engine... for 15k.. for just 200hp? invest 5-6 in the engine and a get a kickass tune. all depends one what you want todo in the long run.
