Spitfire GTS
« on: Nov 07, 2017, 21:24:49 »
So this spitfire started out stock, pickes it up cheap because it sat for over 20 years.  Drove it a few months stock, then ripped the drivetrain out for an upgrade.  Swapped in a toyota 4age with a t50 from an ae86 corolla.  After a little while I pulled off the stock intake and threw a set of ITBs on it with a megasquirt 2 ecu and 2jz waste spark coils.  It is still like this getting 30mpg, I have plans to add a ms2x set up and go full sequential with lq9 coils on the plugs.  And if I quit being lazy I made an adapter to put an AZ6 6speed manual behind the 4age.

Probably won't be many changes for a while.  I've got over 10k miles on the swap, probably 7k of that with the megasquirt.  I have the parts to build a pretty hot engine for it, 12-1 compression, 288 cams, forged pistons and rods, upgrade oil pump, valve springs.  I've had the parts about a year, but either life or other projects have distracted me.

Plus I have an earlier round tail body and frame that I want to drop the hot motor in, and actually make look good.

 It is a fun little car to drive, and with the toyota engine it starts every time, and even keeps up with traffic.

Did you keep the stock rear end?

On this one.  I have a miata diff and uprights for the 67.  I need to finish my bike and ATV before I can fit it in the garage to get busy.

I would guess the new engine is about 100lbs lighter than the original too.

They are within 20lbs or so once you add the transmission in.  But instead of being a race tuned motor to get 100whp, it is stock and has EFI, and actually starts when you turn the key.

Chap I know has a Spit with the 2 litre 6 pot engine from the GT6 coupe.
If it ain't broke, then I haven't been hitting it hard enough.

GT6 was a good looking car.  There have to be better motors for that too. 

Toyota upgrade has to be a step forwards though on this one.
