Default Eunos Roadster V-Spec Maruha 2.1L BUDDY's Build

So after a not so-responsive thread I decided I should start another one in the correct section of CR. If interested you guys can have a quick look on my previous thread here: Buddy's New Look Thread

I have a 1992 Eunos Roadster V-Spec (i.e. RHD). Below is an overall outline of the things I plan to complete:

- Maruha 2.1L stroker upgrade with ITB kit (power)
- lowered and stiffer than stock suspension (handling)
- wheels
- cosmetic stuff to go for the vintage-style look
- minor transmission mods, engine cooling, etc. etc.

Anyhooo, the build starts with the engine upgrade. In search for a reliable tuner, I came across Maruha where they seemed to be quite internationalised with their English/US version of their website. A brandname parts manufacturer with quality products was very important to me. I was sure many manufacturers out there offered quality products. However, the brand was equally, if not more, important. I didn't just want a high-end modification giving me superior yet reliable performance at an economical price. For me as a Miata owner, I hoped to keep most of my mods as JDM as possible (yes, there is some insensible JDM fanboi thing going on here).

So, I came across Maruha and RS Aizawa, with Maruha being what I wanted. From a bit of searching I found out that Chikara was the authorized dealer. So I contacted Ocean and everything started from there.

One very challenging issue about this story is that I live in Hong Kong but I'm from Vancouver. Meanwhile, Chikara/Ocean is based in Vancouver while Maruha is in Japan. Although it makes more sense to work with Maruha directly according to my proximity to Japan, me and Ocean are both Canadians and we communicated very well. Hence, the engine upgrade part of the build starts with me committing to Chikara.

In a nutshell, the engine will be built by Ocean@Chikara, shipped halfway across the world to Hong Kong for my Roadster.

So far the engine is coming together. Maruha parts were ordered in two shipments previously.

Here's the first shipment which includes the 2.1L stoker kit (pistons, rods, camshafts, crankshaft, etc.)



Mahle Pistons, Maruha Racing camshafts, connecting rods, and other bits ordered from Maruha via Chikara










While this batch of parts arrived Chikara, Ocean had been working on my engine base. More pictures of his work will be posted in the next few days. Those would be more interesting than the parts pics I think....

Yes I know you work with Ocean. What's your name? Oh darn it you blew the surprise about the valve cover!

Oh well here it is then...



And yeah, Damon is currently helping me out with suspension while the wait is on for the ITB kit (don't blow the surprise here!).

Default Re: Eunos Roadster V-Spec Maruha 2.1L BUDDY's Build

For those of you who are wondering why I'm going this route with regards to the engine mod, here is the logic behind my decision.

First off, I had to have ITB/NA. You can say its personal preference but my reasoning is because the miata, being a roadster, I felt an ITB brings a tasteful "feel" to this genre of vehicles. The sound, the looks of the funnels, the response, and so on. Some like turbo/SC, each to his own.

ITB aside, I'm running 264 in/ex cams. Why not 272/288 or higher? Because I live in Hong Kong and the weather and traffic here is not as ideal as it is in Canada/US/Japan. HK is a sub-tropical place, our humidity is +90% for 8 months in a year, and +75% during the remaining 4 months. Hence, when it gets hot (summers reach 35-40C), it is fxcking boiling hot. When you pair this with the traffic in HK (those of you familiar know what I mean), there won't be any cooling effect from the radiator. What that means is that the traffic jams are like...not moving. So if the car is not moving and sitting in +35C, I would be fxcked no matter what performance cams are being ran on this old car coupled with the less than ideal idle behaviour of itbs.

So in essence, I won't really be driving that much in the summer in HK. You guys in north america/japan won't be doomed by my same fate.

Meanwhile, HK is a really small city with a lot of winding roads and streets that are short, compared to the long & wide roads or highways we have in North America. The Maruha 2.1L build has a very wide torque band starting somewhere between 2500-3000 rpms. So high revs would not benefit me as much as it would when driving in HK's environment. Of course, this doesn't mean the 2.1L isn't good for 7k rpm, high speed driving/racing. If you've watched the Tsukuba time attack, you know what I mean. The point is, I need the power/torque to kick in earlier in HK's stop and go traffic. That's a big advantage of the Maruha 2.1L build that I can really leverage on here in "Amazing Asia".

The above was explained to me by Ocean@Chikara and it made perfect sense to me based on my own driving experience in HK for so long now. I was quite fortunate that he was so thoughtful to my situation and not just treating himself as a salesman/tuner who just puts together a quality engine. Actually, he was convincing me to run the F-cam, which I didn't prefer, haha. So I'll have to behave myself depending on the weather.

That about sums up the reasoning behind the engine mod!

I just really want to see that mahura stroker on a dyno already

I've yet to see an independent dyno of one. The info on their site makes very little sense.

Looks like a fantastic build, and that valve cover is awesome! Looking forward to seeing the end result.

This is definitely going to vie for one of the highest quality builds in a good long while.

I figure you know this, and it was just for the pics, so you don't need this pointed out, but don't store your cams horizontally. Always store them vertically so there's no risk of them bowing under their own weight.

Oh, and of course, this looks like it's going to be awesome.

This is going to be a sweet build. As others said, I really want to see a dyno chart of a fully built and stroked Maruha motor. I'm sure it won't be for a while, but please make sure you post it.
