Wanting to buy a miata i found. Owner says DD mode is 10psi @ 200whp and is good to 20psi. I was wondering if this build is good for a 1.6l engine and what a safe zone is for it. Here a parts list.
It is fully built with forged weisco low compression pistons bored 20 over block, magna fluxed crankshaft, racing crankshaft and camshaft bearings.rebuilt head, new turbo kit by greddy, aftermarket koyo radiator, innovate motorsports fuel injectors, inner cooler, mega squirt comouter, short throw racing shifter, 3 inch magna flow exhaust, new struts all around. Limited slip racing differential. The transmission is new as well as the 4 puck racing clutch. This car has 17, 000 miles on the current engine

 

Tell me what racing crankshaft bearing is in it? "Racing" means nothing without specs.

Main failure point in these engines are the rods. No mention of rods above.

Innovate injectors? They could be God's injectors and it doesn't matter one goober if they're only 100cc.

Racing differential? Here, I have some racing headlight fluid. It makes your car faster cuz it says "racing".

 

I know, is all i had to work with. Im hoping to get more info tomorrow hopefully.

 

Camshaft bearings?? Did you copy and paste that description or are you to blame for the grammar and incorrect information?

 

don't hate guys


he copied those specs straight out of Need for Speed Underground 2

 

Either the seller is a disingenuous/ignorant pile of ****, or you're about to get in way, way over your head.

 

LOL. Camshaft bearings in a Miata

 

If this is the info you have, either you or the seller don't really know what's what with modifying cars.

I'll pick one example - fuel injectors. Who just says "fuel injectors" without specifying at least the flow rate? The car had fuel injectors when it left Hiroshima, don'tchaknow.

 

The racing crank bearings can be justified since everyone uses the ACL race bearings. But the camshaft bearing mistake cannot be forgiven. Neither can the other half dozen "race" references.

OP, if he can get you a receipt for the internal work done, then yes, it sounds like a good car. 200hp at 10psi seems like a little much, usually it takes more like 12-14 with the greddy system. 17,000 miles also sounds great. I'm always worried about the sub 10,000 mile engines. Why hasn't it done more? Are there big problems? But you don't do 17,000 miles without ironing out most of the issues.

So verify the internals, verify the injectors and MS, and with a straight body, good paint, and clean interior, offer the guy $4k.

 

Curly - Great news! Ever since you started using that avatar, I've been reading your posts in James May's voice. Which is excellent, actually.

OP, I too noticed that you used "racing" as an adjective four times in your post. You also said the car has an "inner cooler", which isn't a thing. Which makes me really agree with Sav - either the seller is a bit of a moron, and you copied and pasted mod list he sent you verbatim, or you don't really understand what you're about to get into with this car.

I'll concede there is a chance you're ESL and know more than Joe Perez and Braineack combined about these cars, but that's giving a lot of credit where none is likely due.

 

i would pay 4k for it, as long as he takes the cam bearings out... lol
cam bearings are too tech for me. :P

 

All it's missing is that Racing window sticker.

 

dude, i dont think the miata can handle the power attained from a racing sticker... he would blow that **** up...
