Frequently Asked Questions
What is the most important step?
Setting the cam and crank timing marks and confirming them by hand before startup - get that right and the rest is bolt-on.
Can one person do this kit?
Yes, but a helper speeds the awkward parts; the real requirement is patience and keeping the fasteners organized.
Is this a big job?
Yes. The timing belt portion is the advanced part - budget a weekend and set the timing marks precisely.

I needed an exhaust replacement for the 1995 Subaru Sambar. Received the part within a few days from OIWA and used the video on to remove the old exhaust and install the new one. It is loud, but there is a slight improvement in the hp. I found this a good option and appreciate OIWA for making this product.
Not only was it a perfect fit and got my car running again, but during the process of removing it i had broken a piece and was able to send them a text where they responded with a link to order that part. Price may seem high to some of you guys but it is well worth it, it shipped fast and is also the only place to get one without importing.
Nice, high quality exhaust. I like it quite a lot overall. Install was quick and easy, bolted right in, and I was pleasantly surprised that it included a new flange gasket. It's a bit louder than expected, but the sound is good.
