Here's a pic of the RX-8 trans and the new Solstice trans on the Isuzu bell housing.

This suits my needs in my RX-8 swap but may be of interest to anyone doing an engine swaps. There's many bell housings that will bolt to the Solstice AR5 transmission. If the Isuzu engine doesn't work out, a Dodge Dakota bell housing will allow me to bolt it to a GM60 engine.

Who's interested? Should I start a thread on it here or are there enough swap threads going?

Before i read the rest of this old thread, i'm going to say you're talking about the Suzuki 2.5 or 2.7.

It's very similar to the KL because it's based on the KL.

Isuzu? Yeh. I wouldn't have thought anything Isuzu had would be worth the effort but after seeing how the engine is designed it seemed like a decent engine. Apparently Honda built it and it's used in planes with a supercharger. How bad could it be? My first choice was the Toyota 1MZ but it didn't have any RWD options.

Similarities can be found in all these aluminum v6s but what sold me on this engine were the many bolt-on transmissions options, the head design, and 6-bolt mains. The cams are mechanical bucket over valve and close together and driven by a geared shaft mounted low on the head. The shaft is belt driven. This keeps the engine narrow and the belt covers low. Should be a fairly light valve train and capable of higher RPM. It's also non-interference. The 3.5L of displacement and resistance to detonation is also a nice thing. Guys run 10psi non-intercooled on it's 9.5:1 compression ratio. Not bad. It does have a cast iron crank though.

That intake manifold has got to go but check out that intake port.

I have a pair of T25s from a 300zx but I'm always keeping an eye out for good deals. What's the price? Wouldn't those be well suited for boosting BPs? Have you tried selling them here?

A bit small for BP. Brain said good for 150-160 whp on Miata. They are T25 but .48/.49 AR. Would still spool good with 1,250 cc per turbo!

Thinking $300 for the pair.

The Isuzu engine is a 3.5L or 1.75L per bank. They might be similar to the T25s I have. Send pics and any identification numbers.

Oh, yeah, I was thinking you were doing a 2.5 KL.

Pictars in links below.

Turbo #1 acquired last week. CA18 DET turbo, .49 AR hot side, .48 AR cold side. No shaft play.

https://www.miataturbo.net/diy-turbo...1/#post1003583

Turbo #2 acquired two months ago. Was told it was an SR20 T25 when I bought it, never opened the box until this week. It's another CA18 DET turbo. Same specs, .49 hot side, .48 cold side. It is a fresh rebuild. Unfortunately for me, I paid $225 as I was led to believe it was a SR20 T25.

I figured $150 each was fair.

That's reasonable. I got mine from a friend who bought a 300zx engine from his friend who hydro-locked the engine. Paid $100 for both. Every once and awhile I get really lucky like that but I'll pay in the long run because ever since I got them I've got v6 on the brain.

I don't know what happened lately but I can't even give away Miata parts these days. I just junked B6 and BP turbo manifolds because no one wanted them. Junked a pile of BP flywheels, blocks, heads, and B6 shortblock, crank, bla bla bla.

How bad could it be? Pretty bloody bad, quite a common motor in a rodeo work utes here on this side of the planet. 3.5 ltrs where the biggest pile of poo!
Most turn into 2 strokes by about 100kms. Chew fuel and oil.

Holden/GM have a Allotec 3.6 ltr motor which the rodeo, work utes, now use. I'm pretty sure you guys run that motor in Cadiliac CTS, Buick LaCrosse plus a couple of others. But these motors also/can have a few problems as well, timing chains sensors etc.
I.M.O. this would be the motor I would pick.

It's built with the same materials as any other engine so I'll give it a shot. The oil burning is caused by a stuck oil ring. There's an updated piston for it. Don't use **** oil it'll be fine.

Game on indeed. I forgot to mention. The engine/bellhousing/solstice combo was a bullseye.

#12 solid copper actually. The RX8 has a power plant frame like the Miata and it's not there. I'm still in mock-up stage.

A little update on the Isuzu 3.2L engine's potential from the 1680hp record holder, Dynomotive.

Stock internals = 450hp (10psi gets it) (piston and valve spring limit)
Pistons+valvesprings = 650hp (connecting rod limit)
Pistons+springs+rods+cams = 700~800hp (crankshaft limit)

I'll be happy with 8~10psi while maintaining the low end/fast spool of T25s on 9.8:1 pistons.

Here's a shot of the Isuzu rod on the left vs. Miata on the right. I tweaked the Miata rod with a programing error on my anti-lag settings. -doh!- If Miata rods are good for ~75hp each I can easily see those Isuzu rods handling 75hp ea.. 75*6=450hp. Supposedly they're good for 650hp which is 108hp a rod.

Exciting swap! Can you explain what it will take to get the wiring working properly?

Old-school computer geeks may recognize the analogy here to the fabled (and occasionally true) legend of the Killer Poke.
