Pinion angles changes with ride height? Doubt that but halfshaft angle will.

If you see the tach twitch, then the coil is not being fired at that time. I would guess it's the black module on the distributor. Sometimes you can wiggle the connector and influence the intermittent problem to occur as well as tapping near it on the housing of the distributor with a brass drift.

1987 300zx non-turbos manuals have 3.9 as do some 200sx turbos though some have 4.1

Mercruiser is a inboard/outboard maker. Mercury is the outboard division. There have been some good innovations in 4 stroke outboards lately. Supercharged inline six of 275hp.

The merlin 9.4 is a chevy 572.........same size as a 396 except for the taller deck which widens it only a little. It's what mercruiser used/uses on the 1000sc engines back in the 1990s. Not sure if they still use it as I usually see 540 as of recently.

I test fitted a merlin 9.4 liter (572) and it went right in. It seems the ford modular engine is damn wide and you might have trouble fitting it. I've seen the caddy 500/501 in a 910 maxima and I really love that pic of the 472 but your choice may depend on availability of parts since that pic above probably has most every performance part made for the caddy engine in one place.

It depends on what S130 the R200 came out of. The non turbo S130 should have the one on the left as well as the S12 200sx turbo R200. The one in the center is found on s130 turbos. The one on the right fits Z31 and infiniti M30 and possibly the S13. I measured the R180 flange that is the size of the one on the left and it does not bolt onto the R200.........the bolt is the same size and thread but the splined part of the shaft is larger.

If you're running a catalytic convertor, zero muffler has a nice low rumble without any harshness. I'm going with two chambered mufflers side by side because of restriction because I like my cars very quiet. Someone here (djz) is doing it but hasn't finished it yet but has pics of two side by side.

I walk the junkyards most every weekend for this kind of stuff but that pic up above sounds like the best solution. I do know that the early toyota camry (84 84) with distributor in middle of the head comes with a intake tube that worked on my 1984 L24e maxima but I didn't use the turbo airflow meter. I'm going tomorrow for one that goes from the turbo inlet to the MAF on a L28 in infiniti M30 car.

I both outside........I will check.........well tomorrow...it's after midnight and the neighbors won't appreciate me impacting away this late. I do know that axle shafts ends that plug into the diff on the R180 are smaller diameter.

Sure the 280zx distributor optical wheel is different than the 300zx wheel but the 300zx wheel is the same as the quest wheel..........I've compared both and have run a z31 system on the L28 as early as 1989. It's just a matter of time before I find a quest/villager/pathfinder/qx4/frontier that is apart so I can see the tone wheel...............that and a real job so I can stop rolling up my change. In my 3 cars, I have found 160.00 worth of change in the last week. If nissan/infiniti hires me either as a tech or service writer, then this will move really quickly.

The quest ecu is sequential, it requires no extra coils, it is fully OBD2 compliant, it runs with a single coil, it expects the same distributor waveform as delivered by any VG30 or VG33 single cam engine from 1984 to 2002, and you can flash it with a new bin file through the OBD2 port. The only "work" needed to run this is putting in three 02 sensors and supplying it the crank angle waveform it expects. To do this, all I need to do is actually see the tone wheel so I can duplicate the signal it creates and the rest is easy though some fancy placement of the 02 sensors in a single log manifold might be needed to satisfy the "two bank" scheme.

The ES and the RX were front drive but some RX are all wheel drive and the RX400h (which I drove as a company car when I worked for lexus) was a really unusual setup with an electric motor in the rear of the car. They were not a whole lot bigger than a differential and one in the front and one in the rear of a little car like a toyota FX (steep hatchback) would be a lot of fun. I'm just waiting to find two of those rear motors for sale.......someday.

Not sure about that second link Grim since it defines an "oversquare" engine as one with a longer stroke than bore.........which is backwards.

I'm pretty sure 1sickZ used to get ridiculous hp out of some pretty stock configurations.

I've been a big fan of the twin muffler setup since the early 80s when I ran them on RX-2s. Good too see you didn't have to angle them over because of height issues. I'll probably be going this route on my M30 since I want to run 2 chamber mufflers to keep the noise down but still get decent flow........plus......I like the look.

The lexus GS has never been a front drive. Back in 1998, it was a 13.8 second rear driver. They added a direct injected V6 and AWD for some models in the last few years since toyota will stop importing the 2jz soon if not already.

I've seen a few old formula race car engine that exhausted like that. Here's a ferrari from 1967 Sure the engine is strange but the fuel tank/bladder scheme is downright scary. Big balls or small brians, the drivers had back then.

Take the drivetrain out of a Lexus GS?

The w41 Quad 442 olds had 190hp with no turbo..........but they do have longeivity issues.

If you want any fuel mileage to speak of, avoid the rotary. I ran them for 10 years and dropped them because of mileage and noise. The renesis is better on gas because of the drastically less overlap.

A sequential injector scheme with a very good spray pattern would reduce the need for turbulence in the combustion chamber. Eventually somebody will go Direct injection making turbulence a non-issue. I wonder when the GM direct injection systems will start showing up in junkyards.

Same dilemma here.

Back in the 80s, it was dimples........now it's grooves. Same theory but what I found was that deposits can remove them by filling them.
