Man i haven't checked back on this thread in a while, and gotta say that suck! One motor i got had water in the block and rust in the cylinders. I got it from LKQ and and i had a new motor ready for pickup in less than a week. Here's my thread on it with pictures.

seadoo

are you keeping the a/c and miata power steering?
I would do this in a flash if I can keep the a/c!

AC yes, no PS to begin with but it is possible.

seadoo

what kit did you use? the V8R kit? Boss Frog?

Wallyman

V8R, rearward kit for the 90-97.

Build Update:

Parts Arrival - Some photos... the aforementioned Leather Boot (scratch and sniff for real leather smell!):



And the aforementioned Robbins top:



I seem to be working in reverse.. the motor is becoming more DISassembled!



The heads are back from the machine shop.. the pile of old parts:



The heads are looking snazzy:



Looking good with the Comp 928 springs!



Still need to clean up the remaining carbon with a brass brush.




The white smears are the residue from the cleaner, not damage of any sort. They shaved 0.002 off the heads to clean up the head gasket mating surface. The set up the springs for me as well, Comp 26926-16. Specs:

Seat Load
129lb @ 1.835" (per box)
150lb @ 1.835" (actual)

Open Load
470lb @ 1.160" (per box)
510lb @ 1.160" (actual)

Spring Rate
505 lb/in (per box)

@ 590 lift (VRX4 cam)
424lb (per box)
446lb (actual)

Coil Bind
1.100"

The shop was mildly concerned that the rates were higher, but after a call to Vengeance (Thanks Ron & Kevin) [Kevin stated they have a lot of success with this cam and these springs without issue - "run it"]and another call over to the guys at Comp Cams [Stated that the springs will 'settle in' after a few heat cycles, and will drop down to the book/box rates] I forged ahead and the heads were built. A new head gasket was ordered so hopefully I can put the engine back together next weekend.

thanks for the info. I think I will do this soon. I want to do a 99+ body and keep the A/C. I live in Central FL, temps can get 100+ with 90+% humidy... Have to have A/C.
The car will be mostly street with one or two HPDE and drags a month.

Even with A/C and P/S it should still be 2600 lbs correct? I am thinking LS6 crate... should make a fun little ride.

PS, that is a nice looking shift boot!

I think closer to 2700, but I could be off.

you need to weigh the car when you get it back together. I am very curious!

Also, All the Factory gauges can be tapped into the ECU pins right? Do you happen to have a diagram or something showing the layout?

Thank you!

Wallyman

iTrader: (1)

I was 2460 pre-swap, hope to be sub-2700. Will weigh for sure.

It can be done tho I plan on all aftermarket. I do have both GTO & Miata FSM wiring diagrams. Stock speedo on the 90-97 has to be converted to electronic, though.

seadoo

is the 99+ gauges electronic? That would make life very easy for me!

Wallyman

iTrader: (1)

Yup, AFAIK it is.

seadoo

Wally, Great information. Thank you very much! Good luck on the build, I am going to be watching very close to see the finished project.

Gotta love Flyin' Miata. I live about 5mins away from them. My buddy Jason used to work there. You should see their Ls-Miatas on the local auto-x track....

Build Update:

Parts Ordered - Ordered up my BLING item.. still a secret, tho!

Parts Arrival - ARP head bolts came in.. look good. Down to just a couple items outstanding (tho I keep ordering more, it seems).

Hope to assemble the complete rear end evenings this week (subframe, diffy, a-arms, hubs, axles, coilovers, sway) and get that mounted back under the car. That will make some room for engine assembly and painting for this coming weekend if all goes well. The main floor bathroom remodel has been a time-sucker and I am this -><- close to being done with that, which is nice. Painted ceiling, walls, cabients and trim this weekend, and just have to get the tub re-glazer to fix his crap product that isn't curing proplery.. 9 days and still leaves fingerprints? WTF I say. The new slop sink in the basement is nice, can't wait to break in that bad boy with some greasy arms.

I'm going to take a guess, chrome roll cage/roll bar.

Wallyman

iTrader: (1)

Nah, nothing so over the top.. it's subtle.. and cheap by comparison.

RedVertTA

iTrader: (9)

I've made my guess (to no avail ), lets see if anyone else can guess what it is.

Hartje

iTrader: (1)

so this could be one of the best documented well put together build threads on Tech. I can't wait for a burnout video!

also my guess is some sort of rice tail lamps!
j/k

subtle... My guess is wheels!

Wallyman

iTrader: (1)

We'll see how well documented it is once I get back to actually WORKING on it with WRENCHES. Heading to the garage shortly!

Close.. but nope.
