hey steve, nice to see you on here.
post up some pics of this new head of yours!

my opinion is that you will never, ever see anywhere near 200bhp from the head work, cams and ITBs. sorry

when you gonna finish MS? you should focus your energy on that mate, you're gonna run lean as hell with all these mods and the half-working motronic.

i'm using megasquirt, but its not fully up and going yet, i have been using the standard motronic for a while on it now, and its not too bad, not sure about gains, it feels much much better put it that way, but generaly ITBs on there own dont always give you much more bhp, i think there more the type of thing that when coupled with wild cams, and my new ported (and bigger valved) head, then i expect to see some good gains, i want over 200bhp, but i think that may need the CC to be increased abit, i am going to work on the bottom over the summer, and i'd like it to rev very high, i'm thinking 8500-9000

steve

hmmm, thats nice that it works with motronic. did you just hook the itb tps to the eninge wiring harness? you dont have an afr gauge do you? I also see you are using an afpr, did you have to mess with that or is it on stock pressure? stock afm or maf?

i wonder if the guys at miller performance could make a tune for it.

thanks

lol i'll answer for steve. he runs without the TPS :O and has trouble when jabbing the throttle but apparently not too much at other times. Steve has a NB02, i've been telling him for a long time to buy a wideband, but he's an engineer at heart and more enjoys the fabrication stuff!
from personal experience, this isn't the way i'd run it. I don't think Steve intends to for the long term either. as a late e36 it should have good lambda feedback to make sure AFRs aren't too dangerous.

In http://www.vimota.lt stock head, custom valve springs, solid cam followers, titanium springs plates, camshafts about 300 deg, stock compresion ratio, ITB, aftermarket ECU and stock bottom they get about 190 hp. I'll try to get dyno graph.

They had only one serious problem. The stock oil pump start to cavitate at about 8000rpm.....

So

well i will be dissapointed if when i put the modfiied head on i dont see 180bhp minimum. but 200bhp+ is more a long term goal, i know i probably wont get that right now, but when i bottom end is done i hope to

let's both do a r/r together when you're up and running steve, will be awesome.
romkasponka, let's have some more details of that one making the 190bhp!!

How do these TB's look from the cylinder head side? Can they be matched to the M42 intake gasket? Also, it appears that the injectors fit in the TB housing. Is this correct?

Nice set-up and nice e36 .

What are you running for upper strut mounts ?

Tonyb · « **Reply #25 on:** March 19, 2007, 10:13:24 PM »

I'd like to have them just for the way they look!

Is'nt that an e36 body? Never mind I see it now!
