Buildup: My quest for NA 180 hp

[Boyracer]

I found the homepage of the car/team:

http://www.prospeedracing.net/historia.htm



I remembered incorrectly, power is over 230 hp, jolly good show from 1,8 liter :p

They do offer stock and racing parts for M42, I have to find out if they sell those hydro/solid lifter conversions... Seems like they are using custom made pulleys, maybe vibration damper too?

Quite a combo, Ford body, BMW engine, Toyota gearbox, Volvo rearend. Still interesting racecar.

Terve.

They don't use vibration damper at all.

Nice photos Freak and welcome aboard! Damn you and your press accreditation

Nothing much happening with the build, still waiting for the ITB's and learning stuff...

[Boyracer]

Well, what do you know... Some parts arrived

- 4 x 345 cm3 injectors from Audi S4 with four nozzle holes, maybe better atomization of fuel than stock too? Should be good for 220-230 hp at 85% duty cycle and still have decent accuracy on idle on short pulses, important with emissions.

- 6 x E36 M3 240 cm3 (sounds awfully low? Flow value based on Bosch part number) injectors with rail.

- Assorted vacuum pipes and rail for E36 M3 ITB's

- OEM M3 ceramic gaskets between cylinderhead and E36 M3 ITB's

- 3 x twin ITB's from E36 M3 :cool:

- Etc.

Had a look on engine bay, might be better idea to build a custom airbox from glassfiber than trying to modify E36 M3 airbox to fit.

[Boyracer]

To continue on the path of accumulating stuff while not getting anything useful done, I have bought BMW Motorsport manual for 95 season E36 2 liter super touring racecar. :cool:

It has 201 pages and it describes every nut and bolt that differs from stock car. S42 engine, engine management, suspension, seats, gage, cooling, bodywork...



Should be very interesting read!

good thread! boyracer, where did the motorsport manual hail from?

[tim_s]

don't know whether you saw my setup boyracer, may be some food for thought?

That looks very much something I would like to achieve!

The manual is from German ebay as usual. I need to take a break from that place, too easy to buy things...

[tim_s]

let me know if you see another one

[frost_dxb]

on the same boat here

Tim, tell more about that MAF installation of Yours.

[tim_s]

that was my old megasquirt 1 extra setup with an M52 MAF. I got bored of MAF after a while and used MAP instead, and been happily using MAP ever ince. MAF is smooth and works very well, got a pretty good map on it, had trouble getting it to have correct AFRs under all inlet temps though, was a little strange. What exactly would you like to know?

[Boyracer]

Few photos from stuff, all in stock condition at the moment.

Now I have the cylinderhead and ITB's so I can start planning the adapter plate between them. I have contact to CNC machining company trough my work and I think they could produce the aluminium plate adapter in reasonable price.

hey, a --ahem-- group buy could reduce the cost to make that plate...

(hey man, great looking project!!)
