So say I buy the Greddy turbo kit for a 1.6.... the only thing I would have to change is the manifold and fuel management? (for my 99)
It's like a house of cards if you try to shoehorn in a kit that wasn't designed for your application.
I.E. if you were to try to install a Greddy 1.6 kit on a 1.8 -- any year 1.8 -- you'd have to come up with...
- custom turbo exhaust manifold that fits the 1.8 head to the tiny Greddy turbo
- custom downpipe to fit the geometry
- since the Greddy kit doesn't come with an intercooler, if you got FM's intercooler upgrade kit, the plumbing is for a shorter block of the 1.6, not your 1.8, so you're looking at customizing at least part of the kit to fit
- unless you're proficient to do your own designing and welding or have friends who'll do it for you as a favor, to pay someone else by the hour to do the above custom work will raise your budget into the range of an FM kit that you're trying to beat, I assume
If you want to save yourself some headaches and money, here's what I'd suggest:
I predict that a lot of guys are going to dump their JRSCs in favor of the new BRP SC.
Unless you feel you HAVE to have a turbo, I'd take advantage of the shift in the market as the JR falls by the wayside and watch Miata.net classifieds for a bargain on a used JR kit for your app. There may also be some BEGI and FM turbo owners who jump ship to the BRP, so you may start to see bargains on used turbo kits too.
