Better build, from SETA to m20b25 or stroker

[reztat]

So I have a sedan with a SETA engine, I want to know is a better investment in quest for daily drive power increase. I have 3 options inside my budget, 1)Have a m20b25 for a steal from a friend in pristine condition but no ECU. 2) Do a stroker but for what I have read it required a lot of money to do it properly. 3)Final option is to put some mild goodies to my SETA, like headers,chip and air filter. The car is intend for daily drive and also I dont want anything that fast do to maintenance. Thanks in advance.

The best bang for the buck would be an M20B25 head, intake, injectors, AFM, engine harness, and DME. The gains from a chip and headers is minimal and the gains from an air filter are none.

Well yes I know, but what about the complete m20b25?

what about it?


I think you're missing the point of what he said- take the M20B25 head, intake, AFM, injectors, etc and put them on the SETA bottom end and you've got a 2.7l "i" stroker. No custom pistons, no other BS needed

You will need an "i" ECU, but they're cheap enough.

Umm ok well, if u see it that way, its really the right thing to do. I need to use the b25 injectors or can use mines?

[jlevie]

You need to use the b25 injectors.

I'm confused. Will the stroker make more peak horsepower than than the m20b25? This conversion is the reason I found r3v two years ago and I'm still gathering the parts. I'm slow because I wonder if it's worth it.

I thought the CR was still a little lower than m20b25 even with SETA pistons. Never mind, I can look that up.

Pointers to any dyno sheets comparing a stock m20b25 to a budget stroker with the SETA pistons and 885 head? I have most of what I need parts wise, now looking for motivation!

[jlevie]

Is performance or cost more important? The best performance will be from an M20B25 transplant using an lower mileage engine (less than 150K) and having the head rebuilt if the mileage is 100k or more.

ive done the i head stroker, very fun to drive, add a chip and 19lb injectors and u got a beast of a daily driver

[reztat]

Another question, I can put the timing and all the setings on my car exactly like before even that there is a differente head?

[dirty thirty]

working on my 327i now cant wait for it to be done.

[reztat]

What parts are you using?, Can it be done with a early m20b25? 86*

Do people use m30 afm's for strokers?
