RMS DYNO DAY 12-5-09 All BMW's Welcome!

[e30polak]

gt25 with turbo outlet off a black top SR :D 120 shipped
guesstament b25 head at the yard 70 bux
b25 intake at the yard 50 bux
Side mount intercooler off a stock sr20 30 bux
custom charge pipes lets say 50 bux
t25 turbo adaptor off of stock headers ?? custom lets say 100 bux
oil lines 30 bux?
and a MLHG 120 bux
and yes I did forget , head studs 200

so far thats about 720 ?? give or take it is possible :D

I think your turbo adaptor price is off by atleast $50-100.

Also, you plan on running the stock ecu for all this? If so you would want to upgrade to the newer Motronic.

What about exhaust? Your car will run like shit with factory Eta exhaust.

for the adaptor manifold , ill make it or my dad. I just need to make the adaptor plates for the headers and i can find or make a t2 flang myself

for now I would have to run the stock ecu maybe with a chip..
to source all teh stuff for 2.7i would take time and loads of more money.

for the downpipe would just be a one 3" pipe , then make a dummy cat and maybe stock piping and muffler from there. Im really not wanting to go crazy boost or anything that would get me puleld over.
Thats why I think half a bar would be fine. would be around 200whp and that good for DD.

[E30_fiend]

Have you thought about head gasket? head bolts? tuning? labor? All that really adds up. And that motor built the way you described it wont last very long at .5 bar.

I think you should plan this out a little better and research some more. You would need to upgrade your ECU as well.

It sounds like someone talked with you breifly about how it COULD work and you ran with it. There are little things that even the biggest gearheads forget about.

no offense to you. Just layin that out there.

[accident]

I'll probably be there, but I dont know if i should dyno the car with a bad wheel bearing :(

[Stephen]

Youre not factoring in all the I electronics. Theres alot more needed than just the i head

Well I plan on changing the head gasket and head bolts anyways so I might as well put a b25 head it so its safer at higher rpms "5500"

Also no one talked to me about it. I pretty much desided to this all myslef. I cant afford a m50 or such. really no point in doing a m20b25i swap unless i just sell the car an buy a 325i.

The goal would only be around 200whp for a fun DD. tuning wise would only be a chiped ecu, possibly bigger injectors.

I think it would be a safe DD. I wont start any work till I find a job.

not gunna do the I electronics. Just the I head and intake for better flow and safer revs

I dont think youll make 200whp on a stock dme but it could work. you should just ad M/S

Possably bigger injectors... Bigger injectors are going to be a must 14lb injectors wont be enough




I wish I was futher down south I want a base number before cams

You cant run "just an i head". You NEED the electronics. and when I said something about the head gasket I meat you will need an aftermarket head gasket. The stock head gasket cant handle boost and the stock head bolts arent meant to handle boost either.

and who gave you the 5500 rev limit number? In a perfect world where you didnt have to swap electronics or any sensors onto the eta motor, you would simply have a 4500 rev limited 2.7i. The motor wont rev to 5500 or 6500rpms without the proper electronics. You cant tune for higher revs on the eta ecu. The ebay or aftermarket chips wonts be formatted for your application.


Long story short, you need to research it more Ben.

There is a huge thread on the 2.7i swap. You need an i head, i intake manifold, i electronics, i sensors, i thermostat housing and thermostat and probably a few more things that I cant remember.

Shoot me a text if you want to talk more about it or talk with Stephen, he was debating doing it too.

also, the stock i injectors are 14.5lb injectors. You will have a WICKED lean condition if you go F.I. You will need at the VERY LEAST 19-21lb injectors.

[Stephen]

Yeah, talk to to taylor or i not to derail the thread too much. If you just want a safe 5500 ( which is only the limit with the mark D chip, not stock) do the double valve springs. It wont get you anything besideds peace of mind though really

[accident]

I chipped my ETA with the MarkD chip and ran it to 5500 all day long. it wont break.

You may want to put us down for the people showing up, but not dynoing their car. I'm not going to dyno mine for sure.

I understand that buddy but what the point is, he CANT run the i head and intake on the eta bottom end simply with an eta chip. There is a shit ton more involved.
