It's time to make it fly...Which motor swap for 2002? m10, m20, turbo, ohh my

[fiftytakedowns]

Hey,
recently got a 318is so I could start a project for my 2002, and I figured you guys would know more about the motors, and power than a 2002 forum filled with purists.

I got a 2002 with the suspension all hopped up brakes done etc. and it's tii motor is not covering it. I just rebuilt the motor, and Im still not getting the rush that I got from my friends STI.

There are some e30s out there that make more power than the STI, and with the weight of an '02 would be madness(2300 w/ fulltank and interior).

Im looking for that torque that throws you in the seat, like the boost of a turbo etc etc.

2000$ budget
(guy in sac built a turbo motor for 2000$)
and I wanted to ask what would be best, coolest, or a irreasonable.
Anyway.

I have a spare m10 block that needs refreshing, so I figured I could do a turbo build with around 7-10lbs of boost. to get around 200 wheel horsepower or so. (it doesn't need to be smogged so I can cam it etc..) would use junkyard turbo components to keep price down.

OR drop in an m20, I have seen them go cheap, so it could keep the price down, and with a reground cam could get some good power with megasquirt etc. once again no smog. not sure if it would have the same intensity/ torque a turbo has though.

Not sure a turbo m20 swap can be done for under 2000$

Are there other options I am missing?
What is the best/cheapest option.

Thanks

A rust free 2002 in good condition is worth a good bit and really good examples command a good bit of coin. I'd think that the best "return on investment" would be to keep the 2002 stock and restore it for sale. E30's can be had on the cheap for a high power upgrade.

Slap in ARP headstuds and an MLS headgasket and run 25 psi.

I agree, but I don't ever plan on getting rid of my 2002. I built the car already, and it is pretty much rust free, i am replacing the rust in the rockers, which is minimal, this summer. I just want it to be way more fun.

Plus I am keeping the stock tii motor so If I ever dislike my turbo project, I can just re-swap no problem.

in addition I dont even have the money for paint, or "real" restoration quality materials.

If your budget is $2000, turbo an m10. You're not going to be able to buy a motor, sort it, turbo it and install it for $2000.

your not going to get this for $2000 but its sick! also no matter what you do if you want power i think your going to end up spending more then $2000. just to let you know.

Im actually a pretty frequent user of the 2002faq, I just thought it would be better to ask you folks who know more about m20's and m10 turbos(which are more popular here) also.

seems like there is an obivous consensus for m10 turbo hah.

[deutschman]

i do not think that a lot of people here have m10 turbo set ups. i could be really wrong but i have never seen any threads about them here. more so on the 02 faq page.
but you will need to do a few things like run a mega squirt set up. you need that fuel injection. i just do not think that $2000 will cut it. turbo manifolds are expensive and so are other turbo parts. i guess you could try and score a nice used one like this, but you are going to need to be lucky. man there is a big list of parts for a turbo build. you should do it though. it would be a really nice set up!!!

400 pistons/rodbearings IE special
150 turbo, intercooler junkyard turbo
200 rebuilt head (source one out)
50 318i manifold from turbo
400 turbo mani
500 MS components
100 fuel injection components
100 sensors
100 for oil cooler.
100 for piping
2100 dollars.
good estimate I guess

considering

m20 swap
m20 motor 100-500 dollars
oil cooler 100
MS 500
sensors 100
cheaper? yet not as fun.

Go back to the faq and read all of charlie mac's blog-titled my 500$ pile of S*&t in the project blog section. It will be on one of the last two pages.
He is a very skilled, capable home mechanic. Did all the work himself and spent more than the 2000. If you want this to be a reliable car, take the time to do it right.

Thats the guy in sacramento I was talking about.
He spend alot of money on a turbo though. I was only planning on using a junkyard turbo.

This is how to make it really fly http://kalecoauto.com/index.php?main...products_id=16


But to make it go fast if your current M10 is in good mechanical order then I suggest that you leave it as is and spend you money on the turbo and engine management. You can turbocharge an carburetor but you are better off going fuel injected. First research and plan out your engine management (how are you going to run ignition and injectors?) then plan out your turbo setup. This part will easily blow your $2000. If you want to make good power you need to have a good setup (junkyard turbos might not be included in this "good setup" unless it is exactly what you need). The saying "a turbo is a turbo is a turbo" is not really accurate. The turbo from a Chevy Sprint is not the same as one from a Cummins Diesel. Finding a turbo in the junkyard that is exactly what you need might not be easy.
Once you have your stuff all figured out and your 2002 turbo running, then start saving your money because sooner to later you will blow something on your engine. Once you blow something then take the money you have been saving and use it to really build your M10 engine.
Then you will have a built engine mated to a turbo and engine management system that has been tested and fine tuned.

My car is already fuel injected.

anyway, I thought of a pretty good plan when talking to some of my friends. There are very many 320 parts cars for 200-500 dollars it would blow our minds. I figured Id pick one of these up, take out the drivetrain (5sp, lsd, ftw), check out the motor, check compression guides, rod bearings etc. swap the 320 motor in WITH megasquirt, or other standalone system with a better headgastket and some ARP headbolts, so it is READY for turbo. then, Research the turbo's and check out richmond pick n pull and sacramento to pick up a smaller japanese or saab turbo. Then the car will be essentially ready for a swap Ill just need to source out the other parts. In addition it will make life easier to take it one step at a time.

good plan?

how much does it cost to swap an M20 into a 2002? Like, what parts are involved?

I figure with a $400 M20, and $200 G260, it shouldn't cost anymore than a total of $3000 for a decent swap+turbo, no?
