How easy is it to install an aftermarket tach?

[Wiseguy]

Hey Booker,

How do I install the cigarette lighter back into that round thingy after I got the Parliament Light all fired up?

[booker]

You put it (back) in one of the fricken lugnuts. At a minimum of 30 mph.

[Wiseguy]

Ahh!

I kept putting it in my pocket and keep runing skin and stuff.

OK, Back to adjusting the valves on this Ferrari F1 motor.

NOOB!!

I also know that lighter has less weight so you can go much further with it.

Sounds like you are right on top of things, I for one can't wait to see the fruits of your efforts.

i thought i was out of turn signal fluid

seriously, why do you guys think i dont know what im doing when it comes to internals?
I know what im doing, i dont know electrical or ignition, thats why i asked.
I know there was a point in your lives when you didnt know about cars.
I never went to school for this stuff like all you guys.

I don't have much to contribute, but i figured i'd offer one question/clarification.

Isn't the R34 Skyline the RB26DETT ? Or is that the Skyline GT-R?

the 26 of course suggesting the 2.6L, and the DETT meaning "twin turbo".

As an aside, the RB26DETT stated output of "280ps", like all japanese cars from that era (NSX, mkIV Supra, Impreza, Lancer, RX7, Mits GTO) is subject to.. debate. We all know the mkIV Supra TT was 300+ chp but it had the same 280ps rating as every other car subject to the "Gentlemans agreement" between the govt of japan and the JDM manufacturers.

So do I think a DC92 vs R34 would be an interesting match? I don't know. Doesn't that depend on the weights of both vehicles, the torque of both engines, the "real" hp of the RB26DETT, and the course being driven?

As an aside, the AE 86 hatch in your sig picture is a fantastic car. My friend has a GT-S liftback that's been partially converted to a track car. Absolute blast to drive, and I wish the entire world hadn't figured that out about the same time I did, because now they're damn expensive - just like S13 and S14 cars (for the same reason, and the same crowd)

Oh. I thought of something else. People that have been building BMW race engines since the 70s probably have a good idea of what RPM these engines can take. I recall asking a while back what you'd need to do to get even 8000rpm out of an M10, M20, or M30. I think a big problem with all of these is the rockers.

I bet you could do an F20C swap into an e28 for way less money than building a 9000rpm 300hp NA M20 engine. Athough i heard a nasty rumour that honda engines spin "backwards"

[Bimmerguy2002]

yeah the entire valve train, no ALL internals are going to be replaced.
Roller rockers especially for high revving. flat tappet dont cut it, and the cam is gonna be about 303 at last degrees, probably up to 315 at the most maybe?
I actually got a chance to drive a hachi-roku (AE-86 DOHC) when they had D-1 in Southern Cali.
Those cars are meant for drifting lol.
Solid rear axle + Limited slip + no ABS = Sideways for days hahaha
its funny how good that car has control in the corner, like each movement of the steering wheel is so percise.
I always wanted to drive the Shuichi Shigeno (S.S.) version, the creator of Initial D's tribute car. Has carbon fiber hood, roll cage, a Suzuki racing engine just like in the movie, that can rev up to 11,000 RPM. In Japan, they have courses where you can drive that car for $$$$
There was a video that has Keiichi Tsuchiya drifting (hes know in the world as the worlds best drifter) the hachi-roku i was gonna show but it wont load anymore, must have been removed. But you can find it on Limewire
Yeah the S14 and S13 are nice, im not a big fan of Nissan myself, they are good, but not me

Usually someone who knows a bit about engine building knows how an engine gets it's spark, and how to read that signal.

Do you know how an m20 or m30 gets it's spark signal, at least? Please tell me.

Until you know this, all of your "expertise" is moot. See, it takes more than steel and aluminum to keep a car running, much less than racing (which you seem to be keen on with your 9,200 rpm goal)

[Bimmerguy2002]

You mean like the sensor reading the flywheel for crank position and stuff to give the signal to the ecu to tell it when to spark?
and let me guess the ECU gets the spark from the coil?

[M635CSi]

I dont know why people bash Japanese cars, i would love to see a DC92 (euro M5) run with a RB25DET (skyline R34 turbo).

The M5 uses an S38 except for the very early models with the M88/3.

you can make 300hp naturally aspirated with an M30 spinning at most 7200rpm, and you won't need a custom crank, intake manifold, etc.

Hmmm, tell me more...

I'm considering building an engine for my '86 535i and have decided 300 bhp is the basis for design.

So far, everything I've worked through requires raising the redline well past 7,200 RPM to get to the 300 bhp number. And that's with a stroker crank, bigger cam/valves and improved intake and exhaust.

We're talking 8,000 RPM and 212 BMEP to hit the 300 bhp number on a naturally aspirated M30 engine; in my opinion.

[M635CSi]

You guess wrong.

Little things mean a lot if you want to be in the 9,200 RPM club...

Roller rockers especially for high revving. flat tappet dont cut it...

Uhh... you are really showing your ignorance with that statement. First off, rockers and tappets are not the same, and roller rockers and flat tappets are not mutually exclusive; I have both roller rockers and flat tappets in my '57 Chevy, and the new Chevy V-8s have both non-roller-rockers and roller tappets. Second, BMW M20s do not have tappets. Third, are your roller rockers going to be rollers on both ends, and if so, how will you adjust the lash?

You mean like the sensor reading the flywheel for crank position and stuff to give the signal to the ecu to tell it when to spark? and let me guess the ECU gets the spark from the coil?

Those two statements are mutually exclusive, and neither is correct. The flywheel sensors tell the ECU what the crank position and speed is, not when to fire the spark. The ECU determines when to fire the spark based on sensor inputs and the spark map. Given that the ECU triggers the coil to fire the spark, how on earth would it get the spark from the coil? That would be circular logic.

[Bimmerguy2002]

You guys make me laugh.
i never said what valve train the M20 used in my post, i made a referance >_<'
Ok, so what do you mean, coil, distrubutor, ECU, ignition wires, sensors, spark plugs?
Thats pretty much all the parts to make the spark.
Sensors usually indicate when to fire the spark
Like in variable spark timing, or a distributorless ignition system, or like in a mis-firing system.

Just RTFP. I explained what I meant. The comprehension problem is on your end.
