update

[Jon_Bmw]

Nice pics alex, we've been waiting for those, it looks mean with two 'coolers. I think the scoop idea will be fine as it seems to make sense, bit like your brake duct vent i suppose. I can see it all starting to fit together.

I've just aquired an intercooler of an astra diesel for next to nothing, just got to find the right place for it now and plumb it in.

Mark i've gone back to stock injectors and spark plugs about a 5-6 hour job all in all, and it idles nicely, i've changed the AFM the other way so now the spring is loser. It idles like a normal 325 with a very little bit of hunting, but unfortunatly pinks at anything over 4000 rpm but you actually don't need it over that. Pulls very nicely dispatched a celica with no problems. I need to increase fuel pressure more, perhaps with one thats got a gauge on it so i can see what i'm doing so that it doesn't pink.

It lasted the half hour drive each way, and it was bloody hot(outside) so that was good news. Next jobs:

1) cold air feed and get rid of the horrible bend between AFM and turbo
2) plumb in the intercooler
3) If that doesn't help with the pinking add more fuel(adj regulator)
4) Dump valve for that whooooosh chirp

Do you need a cold air feed if your running an intercooler ?

and yes i`m on stock injectors and raised fuel pressure (for now)

Not for long dude, I'll post the yellow ones on Monday

Hello folks

Mini update from me

charge pipes made,welded,painted and fitted, now have a fully enclosed charge system , and boost , vlovo intercooler just squeezed inside the stock front end, phew !

Sal will hopefully put some pix up later on or tomoz, sounds superb

still waiting for the light greens ...... then we're done

[lentec]

Ant ive mesured the the intake air temp! it was running 77degC with no water injection!!!
21degC with!!!! thats a 56deg drop!!
gave it a good hard run (about 5miles!) when i got back the boost pipe was colder than the intake for the charger!

[Ant]

thats a serious drop dude !!

77 was lower than expected TBH, you just know that mill is drawing long and hard on that superdense air

Howz the running now, have you needed to tweak for the temp drop ?

[lentec]

Was thinking it should sort its self!
had a bit of a tune on the ignition side (think it was too retarded)
but its fookin quick as said by my mate who came out in it!!
he drives a 250ishBHP integra type-r turbo that i helped build!!
so its getting there! just got to dream up some way of switching the water injection automaticaly?!? i know the m3d is capable of it just not sure how yet

[Turbo-Brown]

Think it's in the first screen isn't it?

Under something like "Temperature Events"? You can get it to earth a connection when the inlet air temp goes above a set threshold

Got thursday and friday off this week so hopefully mine should take a leap forwards. Keep having dreams about my first start up.....not conducive to decent sleep! The oil pressure gauge seems to feature quite heavily

[Turbo-Brown]

Do you need a cold air feed if your running an intercooler ?

Doesn't hurt. The temperature rise due to compression is a relative thing so if the air entering the system was at 40degrees C, the pressurisation added 20degrees C and then the IC took 15degrees out of it, the air'd be at 45degrees C.

If it started off lower at say 20degrees and the rest stayed the same, the air entering the engine would be at 25degrees.

(Those figures are complete bollocks and just made up to illustrate the point BTW )

Anyway, how you getting on with those flanges? Seems to be a good idea to spend a lot of time welding them and clamping them to something very rigid too! We welded one up for a mate's pug engine and it went REALLY banana shaped! Took some manipulation in a big ol' press and then a milling machine to straighten that one out

[deano325t]

I haven`t done anything with the flanges yet Alex..
I`ve had a shipload of other stuff to do..been neglecting my car ..
just getting back into it..

I`ve got a spare engine ,I thought I`d bolt `em to that to weld,
you think that would work ?

and "oh i see" to the intercooler/cold air feed

[Turbo-Brown]

Guess it'd work, but then a voice in the back of my head says it might just pull the studs out of the head.

When I do mine, I'm planning to G-Clamp them to a bit of hefty box section steel. Something like a 40x40x6 or something that's unlikely to bend. Either that or I've got a nice flat bit of 3/4" thick steel kicking about

[lentec]

I welded mine on an old head the studs didnt pull out!

Mini Update

Managed to mount the new TPS on a OEM TPS bracket, drilled a few extra fixing holes to give me some adjustment also.
Today I'm borrowing a 16mm tap and die and a 14mm drill and I'm going to fit the coolant temp sensor........then stuff the air temp one somewhere in the TB boot and see if I can get her to fire up........getting closer now.....but I'm just so slow compared to you lot....must catch up

And yet again I'm waiting on more parts to arrive from the states, lets see how long this package takes to get here

[Ant]

another update from me.....

The light greens are here !!

thats my set not yours mark BTW 11 days from order to in my hand, including a customs charge

ah well, almost there

Bugger , well you did order first I suppose

The guy in the states is getting the LC-1 out of his other car today, so should be in the air by the end of the week. Then I'll be down to make you a few cups of tea and tune these puppies!!

Any luck with those photos you were waiting for Sal to upload?

[buster]

what light green injectors ?
Ive got a set of green e36 m3 ones if thats them.I dont need them.

[e30_Turbo]

what light green injectors ?

Light green's are 42lb ones or 440cc/min, 2.95 times bigger than std. I'm not 100% sure what the M3 ones are, but I bet they are not big enough for much more than the a few psi. The yellows maxed out at 5.5psi, thats not half of what I'm hoping for now

Do you know what flow rate they have?

[Turbo-Brown]

Isn't the pressure on the Evo engine higher at something like 5bar as opposed to 3bar or something like that to make up the extra flow?

[buster]

yeah it is,5 bar.
These injectors i have i was going to replace my 535 ones i had in the 325 engine ,i got hold of a set of m3 injectors from Iain,(hartgeh27) but im unsure if they are from the evo.I never got around to fitting them.

[Jon_Bmw]

Arr seeing as you are all talking of fuel pressures... The m20 standard runs at 3.0 bar i think, i need about 4 bar pressure, is there a way of swaping over the OE regultors from something like an m3 to get 4 bar pressure. I ideally want about 3.5 or 4 psi of pressure, any ideas are muchus apriciated.

Jon

[Ant]

the M20 style FPR only goes as high as 3 Bar dude, the S50 type is no use , wrong fitment

have a gander on Ebay for a seller calles 800bhp, myself and mark bought ajustable RRFPR ( boost dependant ) to get around the same issue Jon. I'll see if I have his details to hand when I remember where I put the info

another quick update (while im waiting for insurance)
have been trying to find stuff that needs finishing so http://lentec-e30.tripod.com/index14.htm

Will defo flow a lot better what do you guys think?

[lentec]

Its all legal!!
T&T & insured!!
So its out for some fun tonight

[Theo]

I really should stop looking at your website, everytime in sorely tempts me into spending alot of money. Whack some videos on with sound when you get the opportunity, have fun, lucky git!

[glenn]

exellent pics on your site mate!!!

have fun tonight
just be carefull with all your hard work.

cant wait untill this day comes for me

[lentec]

Another delay Got a nail in my tyre!
Good job ive got a pair of 215 40s on my mates old honda wheels!
Will get em changed over i think!

Still thinking about taking it to work in the morning

[Ant]

You and me both Len

Fcuk it, its Friday, why not I say

[lentec]

Why not indeed! other than the rain and bloody nail still in my tyre!
So i went to work in other car! Got here n decided to go home to get it!!

It needs a lot of tuning!
Runs great without s/c and not bad with! think it needs more fuel
and a bit more retard top end!
Will have a go setting it up again later!

[Ant]

how you getting on Len ?

I have the part and full throttle pretty much sorted, I have cheated a little though and enable the 02 sensor closed loop when cruising, looking at the datalogs I am 8% overfuelling between 4 and 6K rpms.

The 02 will reduce the duty cycle for me if the TPS ADC count remains unchanged for more than 5 seconds, its helped a bit, found I had a surging problem on trailing throttle too, sorted that by reeducing the fuel cutoff amount , it still cuts fuel but the ramping down is much slower now, was getting worried, ruined a prop guibo in 3 days not much fun in the wet on r/bouts as it was

I fear the hard work is really just starting for us all

[Turbo-Brown]

Yay!

The TBs are getting there

[Sjoerd320i]

oohyes very nice

[lentec]

Ant im having few probs that was expected tho
You saying about the O2 sensor i dont think mine is working The diag data says sweet F/A and im sure i wired it properly!

Also having charging problems or lack of! think im gonna swop to one i know is good

My boost seems a bit low so im also gonna rebuild the s/c outlet adaptor thing
to check im thinking washing up liquid over the pipes

Alex lookin keep it up!

[Ant]

Len probe the signal wire from the 02 with the engine running, set the multimeter to measure mV or range in the 2V area, you should have 0.52V ish @ stoich, say +/- 30% , if you need another NB sensor I have a few you can have NP @ all.

alex, those are looking spot on M8

[lentec]

Ant ive mesured it @ idle in range 200mV read 145.7ish
