This is perhaps a slight threadjack (Sorry OP, but you have a 1.6 too!), but would you say the limit of the 1.6's stock rods is 250rwtq or 225 rwtq? I've heard two different figures on it, Brainy. From this site, even!

Do yourself a favor, pull the engine. Then take the time to clean up the factory wiring in the front of the car, cut a big hole for "new" wires to the turbo parts, drill the oil drain further back towards the trans, cover the under-side of the car in DEI tunnel matt, and plan this out. Learn from what I say, those compromises that "would just take too long" will haunt you. It was nice to pull the head off this winter and clean-up all those little things and I feel a lot safer in the car now with more reliability and more safety.

yes, because 25wtq difference between two completely arbitrary figures will "break the camels back"

I'd assume figures in the 10%+ range are potentially make-or-break 18psi.

F it, how much money would be waste buying a built long block from TSE/Renown or the like. Looking around $4000 shipped including core charge.

10% range of what? a made up number?
some blow up at 200 and some at 300. the 250 number is just something we pulled out of our asses. Not saying that's not the "ballpark" but you can't derive specifics from guesstimates.

I know this hence why I posted their names


Question is how much does it typically run to get the motor and source the parts myself and have work done somewhere?

A ton. It's a god damn miata. Get a 10mm and 12mm and take the motor out yourself. Don't be a bitch.

Both cost of motor and work are dependant on your geographical location. As an example, I am extremely lucky to be able to source an early high-mileage 1.8 for $650-$800, whereas I've heard other people on here talk about sourcing low mileage 02-05 VVT's for $700 easily (Those are $1.2k+ where I am typically). Work is equally dependant, as it depends on shop's labor rate + labor put in.

Even arguments about warranty come down to what you have access to and local policies vs. vendor policies, so it's something you'll have to put the time into finding this out for yourself.

I can do the swap but I'm talking about motor work.

Yeah and as I am in the middle of frigging nowhere in a hick town I don't think i'd trust any motor shop within a couple hours of me




I can pay these vendors $700 for a core charge and have them build it right, to my door.

Yep. Freight costs $200-$300 last I checked with an engine builder.

Considering the time it saves you (Which is significant), and how much you get, a crate engine from a forum sponsor builder is a lot better of a proposition than it sounds initially. I'm seriously considering going with a TSE longblock rather than farking with it at this point.

I would go with Trackspeed in a heartbeat. It would be difficult to get the parts and work that they do from anywhere else for cheaper. And when they build you an engine you know it is built right.

You'll love this. I just scored a VVT engine for $450, I paid $700 for a wrecked 99 swap car, and I paid $1700 for machine work on the 99 engine for my track car, $300 in labor on a valve job recently.

After 100-hours on the track driving in extreme anger, it really makes sense to build a forged bottom end and worth SS valves if its a track car. This way you can set it and forget it...at 300whp. Also, do a VVT swap, it's worth it.

are you shittin' me?

I'd say 225-250rwtq is a good ballpark figure, for ALL model years.

I'm not smart enough to know how much clyinder pressures and RPMs come into play, like winding a lack-luster rotrex up to 300rwhp on a stock 1.6L could peak out at a mere 200rwtq.

.......$450 for a VVT? I'm green with envy. How the hell did you manage that?
