On monday 05-19-08 the block, crank, pistons and rods were drop off at the machine shop. Should see them back sometime next week

[CT SVT]

update

rear diff replace w/ J-spec GTX rear LSD diff. no pics sorry

[COSitsWORTHit]

What kinda power can the old trans handle? New trans power capability?

[CT SVT]

old transmission is good for 200 flywheel hp, J-spec around 300 flywheel so we want somewhere around 250-275whp

Update:

Engine still at machine shop, should see it sometime this week. We called CorkSPort and told them to to change the thermostat location from the right side to exit the front of the cylinder head. This change is because we are now going to convert the GTX to a RWD beast. We pick up a Miata Transmission and other goodies. Right now we are taking alot of measurements for a custom subframe to be made to hold the engine, transmission and the relocation of the steering rack. Seems the GTX already has a rear subframe and a rear diff all needs to be done is have a custom drive shaft made to connect the transmission to the diff. Of course the are other little things to change but it will be done

I'll pick you all posted

Seriously awesome build. Don't see too many clean GTX's anymore :/

[CT SVT]

Update:
Well we did alot of thinking and we are not going to convert the GTX to RWD. We don't want to cut up a very rare Mazda. So we are sticking to the orignal plain. The new CortSport cylinder head is here and the block is come.
CorkSport Cylinder head. Everything you can do to a cylinder head this one has it. Also has CortSport custom turbo cams and bigger valves.

no we are not going for high horsepower. looking for around 220whp but the stock 1.6L turbo only put put 110whp at 12psi so 220whp should be a blast

[slverfocus13]

you are looking for 220 with the 1.8 or with the 1.6
with the 1.8 GTX shouldbe bad, i have seen 176 in a stock mode in an escort with better air intake, and bette rintercooler at stock PSI. but with like 195 TQ.
220 shouldnt be that hard, just throw a NZ head on flows better.

aand glad your sticking with AWd, a rRWD set up i looked into also. (using miata front end subframe and spindle and all, and a stock rear end,, there good for 250 HP. (was going to go with an RX7 rear)

but love wwhat you all are doing. keep up the work. and pictures!

the 1.6L is gone sold. the 1.8L when it was in the Escort made 202whp 222wtq at 15psi. the GTX doesn't have the u.s spec rear diff. we install the j-spec GTX rear diff that we got from CorkSport.


nothin is done to the transmission. the j-spec transmission should hold 250wtq but people have damaged there j-spec transmission w/ 275wtq. so i like i said before 1.6L did 110whp 125wtq. now goal w/ th 1.8L is 220whp 250wtq. but knowing this 1.8L engine is good for 400hp. the engine will have other planes after we had are fun w/ the GTX. Thinking in a year or 2 we would install it in a Miata and let out the engines true power. but for now we want to make the best GTX we can.

side note the cylinder head, and the new block internals are made to rev to 10,000rpm w/ no problems

[CT SVT]

Update:
We just put it together to make sure everythig fits. Sorry if the picture looks bad. Takin by my cell phone. Will have better pictures soon. Oh we are not using that exhaust manifold just yet. We are sticking w/ the stock exhaust manifold for now.

[slverfocus13]

we are trying, Ray we are trying.

Update:
Well, we had couple hours to play w/ the engine today. Torque down the cylinder head, installed the intake manifold, install Gates Racing Performance Blue timing belt and other new parts like water pump,ext..................
The exhaust manifold will come off soon. Its just there to look pretty.





This shows the Gates timing belt loosely install(fully timed, tension and cam gears set to zero degrees now ) and SR Motorsports adjustable cam gears

Will keep you all updated.
