Swaps, Turbos, Buildups / M44B19 Racing Engine

« on: January 22, 2010, 04:08:08 PM »

The fun begins beyond 8000

Boyracer Honda S2000 got 85mm Bore and 88mm Hub, and still 9000 rpm is redline. But you are right ... smaller Hub would be better for High Rpm.

strypt: Does your friend use 88mm Crank from Diesel?
If he got issues with the trigger wheel, why doesn't he convert to M42 trigger wheel?

Boyracer Yes M42 does have stronger Bottom-End, but if you go for Stroke with 88mm Crank, it is better M44 (my opinion).

nuvolarossa This is why, I would go with used Evo Pistons first. We will see how much should they be reworked.

M42 Head has 33cc Volume too.
(S14 - 42cc /// M50B25 - 34cc /// M52B25 - 36cc /// M3 USA S50 - 32cc
/// M3 Euro S50 - 32cc /// S54 M3 E46 - 33cc /// M5 S38 - 34cc)

It is very interesting, but the ///M Power after S14 got smaller Chamber Volume. :confused:

Everything about the BottomEnd guilt for M42 too.

The good thing is, that you can buy stock Evo Pistons for 100$, and they are very strong and forged from the factory. Together with second hand diesel and 135mm second hand M20 Rods ... you can stroke the Engine for under 1000$ and It will still be very strong.

Letsplayskatch, where did you order your Catcams? Tell me what are your impressions .... idle, power, where does the power come?

I can choose between: M42 1st Gen., M42 2nd Gen. and M44 ...
I would go for M44, because after all I've read, the Head is better, it is 85mm bored from the factory and I think the stock head can rev more, than M42. And in my case this car will be for fun and track, so I can go for the most agressive setup, that could probalby be ok for few thousands km.

There is also an EVO Piston with Comp. Hi. 28,7mm and Dish 21cc
In this case: 140mm Rod => 0.55mm above Deck
=> CR = 1 + 511.17/[33+10.1+21-3.2] = 9.4:1 /0.55mm above Deck/

Past few Weeks I was gathering lots of Info and now I would like to share what I've learnd and what I am planning:
 

Bottom-End
Crankshaft + Bearings from Diesel: 88mm Hub (16.6kg) Stock 13.2kg
Eagle Forget Conrods: 135mm (22mm pin, 540g) Stock 532g
Wiseco/Mahle Forget Pistons: 86mm (22mm pin, 320g) Stock 446g
Headgasket M44: 1.74mm

=> CR = 13.06:1 /1.85mm over deck/
     Discplace: 2044.7cc = 8.6x8.6x8.8x3.14159  (511.17cc per Cyl)

Eagle Forget Conrods are the cheapest on the market: round 400$
Lucky for us the Mitsubishi Evo after 92' are 85mm with 22mm pin.
The Evolution 86mm Forget Pistons: round 520$, but Stock (good for more than 300 hp) they cost something like 75$ each.

About the Pistons: I've made some messurment and what I found:
88mm hub + M44 Piston + 140mm M44 Rod = 2.25mm over Deck
M44 Pistons got 30.4mm Comp. Hi.
The Evo Pistons Comp. Hi. is however 34.7-35mm.
which means:
88mm hub + EVO Piston + 140mm M44 Rod = 6.85mm over Deck
88mm hub + EVO Piston + 135mm Eagle Rod = 1.85mm over Deck

=>
1.85mm = 10.7cc
M44 Chamber Volume = 33cc
M44 1.74mm Gasket = 10.1cc
Evo Pistons (9.3:1) = 10cc  /there are 9.0:1 and 8.5:1 ... so lots of choices/

CR = 1 + {511.17/[(33+10.1+10)-10.7]} = 13.06:1

CR with 2.04 M44 Gasket = 12.57:1

I just don't know what would be safe as a size above deck, but I think a thicker gasket and little bit shaving the pistons would be enough. I am looking forward to at least 12:1 CR

----------------------------------------------------------------

M44 Head
35mm Intake Valve
31.5mm Exhaust Valve
Catcams
Reworked Head
Stiffer Springs (dbilas or Catcams)


Int Valve from S54 (E46 M3) /117mmX6mmX35mm/ reworked to the same length as M44 Valve.
Ex. Valve from Supertech

There are 2 Options for the Cams:
I. Catcams 283/284 (PartNr: 1301701) - used with O.E.M Parts
II. Catcams 312/304 (PartNr: 1301752) - used with Stiffer Springs and Solid Lifter (Pushrods)




As for the Stock M44 Head:
Beehive Valvesprings /37g/
Int. Valve 33mmX6mm /47g/
Ex. Valve 30.5mmX6mm /47g/
Hydr. Pushrod /45g/

Alone here everything is much lighter than the M42




So I would be glad to have a little discussion about the Camshafts. For how much RPMs is the Option 1 good (284/283 with O.E.M parts ... probably stiffer springs) and up which point does Option 2 make sence?

Swaps, Turbos, Buildups / Buildup: My quest for NA 280 hp

« on: January 18, 2010, 10:33:25 AM »

Oh .. thanks for the Information!
 
   What I ment is an comparison:
--- ITB M3 E36 Modified to fit on M42B20 ---
VS
--- M50B25 TB with Custom made Intake on M42B20 ---

because of the costs, if there is not so much difference ... the solution with the M50B25 TB is very good.


Additional:
About the P54 Motorsport Engine, I've read that FIA have restrictions about the TB size: 64mm and that is why, thy use Single TB. But the Engine is very fine tuned and without ITBs got unbelievable results.
Another interesting Fact ist that P54 use 232mm long runners, which is the same as the aftermarket Honda S2000 Manifolds, which gives the best torque around 6000 rpm. Honda S2000 got indeed single TB, but
as a performance modification there are lots of aftermarket ITBs.

Boyracer, where did you buy this Clutch + Flywheel ?

I saw that you will use dbilas springs ... are there any other options for aftermarket stiffer springs?

And I was thinking something else ... what would be the difference between modified intake with M50B25 trottle body VS ITB from M3 E36?

Nice Project!

I just found some very interesting information about 35mm valves! As we know the valves from M62 Engine are little bit shorter than the stock M42 valves. Well I found this:

M3 S54 Valves 35mm X 6mm X 117.50mm   (51 gram)
M50/52 Valves 33mm X 6mm X 106.10mm (those are the same as M42 Valves)

So it will be much easier to cut the M3 Valves than Machinework the Head for M62 Valves.

Swaps, Turbos, Buildups / E36 Modified

« on: February 26, 2009, 08:07:41 AM »

A short update:
  1. I bought the M42B18 Engine. It is from an E36, the owner says the condition is good ... but we will see
 
  After some thoughts I've decided to go another road



  2. I bought this brand new K04 (Audi S3) Turbo for almost no $.

  Here is the Turbo-Grafik:




  I have also:
  3. Injectors: Bosch 470cc (they are from Vauxhal VRX or something like that) brand new too.
  4. Innovate LC-1 Wideband
  5. MegaSquirt (mounted in Motronicbox and use the OEM Cables and Sensors).
 
  And I will go with M3 Brakes all around and M3 17" Rims and M3 LSD.

 Best Regards, D.S.

Yesterday I was looking for a Knock System (Detection) and I found this one.
It looks very nice and I was wondering if someone has tried it?

 Best Regards, D.S.

Swaps, Turbos, Buildups / Turbo Friendly?

« on: February 24, 2009, 07:47:01 AM »

If you use higher octane fuel and I am not sure, but some colder sparking plugs, you could run on 10-12 psi. But at the end it depends how you tune your car (A/F mixure, ignition). A friend of mine run M40B16 on 12 psi without problems and the engine blew on 18-20 psi and he told me, that 10 psi is like a friendly boost.

Engine management / Megasquirt as Piggy Back

« on: February 19, 2009, 11:23:36 AM »

This is how it could be done: 4 diods for the 4 coils, which adds the signal and for the MS it will looks like one coil working 4 times .. like a distributor. It doesn't sound complicated and I think I will go for it. After all I can always go for a Spark and Fuel with MS.

Thanks for the usefull info. I will stay with the stock cams, only little bit ajusted. The car won't be this summer as fast as I want, but as a next step I will install MS and than go for some boost. But for now I've got lots of work on the engine-head and on the car at all.

The sunroof will go away too.
Yes, I ment "adjust camshaft timing" ... but I've found the information. Intake +5 degrees, exhaust stays as it is. Not good in idle and middle rev, but the car will be only for racing, so it will go most of the time over 5000 rpm.

Thanks to Boyracer I've read very good and important info about the head modifications and I will try VW Lifters (49 g) with dbilas springs and chip for 7800 rpm. I only don't know for how much RPM the OEM Cams are good? If someone can help :rolleyes:
Dbilas offers regrind for 160 euro pro cam, so together 320.

Hi everyone!
     In this threat I will write you about my car for fun
This car will only for fun and racing. My "normal" car is an E38 (btw very nice car) so I need a car for fun (drift, racing, track). I had a E36 316 with no extras and I couldn't sell it for a good price, so I've decided to make something interesting of it. The reasons are few: It has no extras (very light and nothing to sorry when a get inside with the flex ), it has M-technic bumbs all over and it is M43 ... so the swap to M42 won't be something difficult.
     So what will happen:
    1. Stock M42 Engine inside.
    2. Modified Flywheel (5 kg)
    3. The Engine-Head and Block (cleaned and polished), some new parts so it should looks like new.
    4. What is not needed will be removed. The Battery will go Back in the trunk and problebly replaced by a Bike-Battery.
    5. Differential from 316/318 iA (it is 4.44) so the 5 gear on 7000 rpm will be app. 190 km/h. Diff will be modified to LSD (25%) , probebly OEM from E36 or E30.
    6. Brakes - Infrond stock from 320 E36 (286 X 22 Ventilated), Backward (Disk-Brakes from E36 /the stock 316 has no Disk-brakes/).
    7. 195/50/15 Toyo Proxis R888 Semi-Slicks
    8. Inside everything removed and cleaned.
    9. Strutbraces on both axes
    10. Chip with rev limiter on 7000 rpm
    11. Modified exhaust-sys, cats removed and some more modifications

   So these are some of the things I am planning. I have some questions though:
   1. What should I expect as a weight reduction after removing interiour, the stuff in the trunk and the modification of the battery. The car has no AC?
   2. I've read that the OEM cams can be not as originaly mountet but few theets difference (i hope you can understand what I mean, my english is not as good as I wish). Make this modification a difference and if someone can give me some more info about that i would be very happy and thankfull.
   
   Here are some fotos of the car:
