Looking forward to seeing this on the track sometime this year, Paul. I haven't seen it with the new engine, yet; in fact I think the last time I saw it is when you lost the last one.For all things 24v, check out Markert Motorworks!Originally posted by mbonanniI hate modded emtree, I hate modded cawrz, I hate jdm, I hate swag, I hate stanceyolokids, I hate bags (on cars), I hate stuff that is slowz, I hate tires.

nice power.....wow....
how much lighter is the m42 over an s5x?.....
do u ever run out of brake w/ that set up........altho u r pretty lite..
Can u share your spring rates you usually run?....feel free to pm or e me.......thanks.
Really enjoyed the vids.....I love sitting down and just driving!

I am not a fan of the stock m42, but what you had done to yours is awesome! Great job! Post more pictures! :pMtech1 v8 build thread - https://www.r3vlimited.com/board/sho...d.php?t=413205

I will say it was not cheap, we could have gone to an S52 or something for MUCH less money, but we wanted to stick with the lightweight theme of the car.
The engine that came in the car was a Metric Mechanic 2.1 Rally M42, it made about 160 at the wheels from what I recall, it was fairly strong in the car, but it exploded in grand fashion.
When I say basic car, I mean the rest of it, suspension is stock e30, no geometry mods, just bolt on stuff you can get anywhere, even has non-adjustable dampers..
Stock 318 brakes, with PFC01 pads, the diff is not stock, but again, bolt on type deal.
Rebello is close to me; was considering a built 3.3L street S54 but the weight package and aggressive high rpm attack of a 4 cylinder engine has always allured me (rx7's and sti's is the background)
What is the service interval of a M42 built like that by rebello?
you can run 91 pump gas on it?? Do you happen to have a dyno sheet? I'm sure I can ask them for one if you cant dig it up.OBD1 M54/M52TU swap as a M50b25
Z4 non powered steering rack fits e30
Euro e46 2005/6 320d 6mt gearbox into E30 with M20 hardy and beck 1985 327s engine

Not sure how much lighter than an s52 this engine is, but I suspect a lot.
The Metric Mechanic engine was in the car for a couple years I think, we blew it up the first year we had the car, however, we were revving it too high, unknowningly.
This engine has maybe 10 hours on it, if that. Plus, we had to re-bearing it almost right away after an off track punched a hole in the oil pan...
I am not sure how long we will run it, the goal was to not have to touch it for 2-3 seasons, hence the low rpm we run it at (7500 max).
I have dyno sheets, I'll post one later, when I am on my home computer.
It has custom JE pistons and custom Carillo rods. ITB's are TWM/Borla. The motor runs on 91, but we run a small amount of Torco additive to be safe.
Brakes are no issue, ever, spring rates are 500f, 700r, with Bilstein race dampers from Turner.Paul

The blow up vid is the MM motor, connecting rod broke just below the wrist pin, completely destroyed the entire motor, the rest of the rod kept slicing its way through everything in its path, block, pan, subframe, starter, nothing was salvaged.
The spring rates work well in this car. I'd like to someday change the rear geometry, get the DTM kit or something similar, as it does struggle mid-corner-off on the power, especially in a bumpy corner.
Does doesn't put power down like an e36+ chassis.
Yes Rebello makes power, he makes some pretty sick numbers out of a true 1.8L GT3 motor as well, more than what we have, but thats big compression, race gas etc.
But in all honesty, our motor makes about what it should, pretty standard power/cu in in the race engine world.
Probably be in the 300hp range at 12:1 on race fuel.Paul

The engine we're building for my 16v vintage racer is a 2.3L twin-cam (Cosworth "Coscast" head) with 10.5 compression and a 7.5K rev limit. We have custom cams being built by Hasselgren Engineering, a genuine DTM manifold, and a twin-Weber DCOE 48 setup designed and tuned by a winning Formula Atlantic engineer. If I break 240, I would be very pleased.
Guys with a similar build as mine starting with a 2.5L engine and 11:1 compression are making about 270 reliable HP. If Rebello can match that output with just 2.0L on 91 octane, then they must really know their stuff!sigpic
