Well, I finally got an s14, sold my vert, hatch, coupe, and now have this, should be the last 240 i'll ever buy, i'm tired of building cars from scratch.

Image

It's a 1995 base model w/ stance gt-r coilovers, 300zx brakes f+r, currently motorless but I have a powerplant for it.

Suspension wise it'll be a mixture of our own suspension parts, powered by max, and ISIS. The motor will be built by us and tuned by MA Motorsports.

The KA24DET, bored .20 over, eagle rods, super tech pistons, super tech valve train, GT28 Turbo charger. I'll have around 400-450whp after the tune.

Body 30mm rears, kouki front end, blister body panels, wheels.

Pics to come with the engine re build, and the cage and body work to come!

Well my motor is built already, but this season was a little hard on it and the bearings went from oil starving them, something must have clogged up the passage ways.

So it'll be better than ever, with the new intake manifold we made, the vmount intercooler configuration, and all the other stuff we'll be trying out on this car.

even with the t2 flange? i dont see how that t2 can flow 450hp. i have heard it can be done but thats just crazy lol. are you porting the turbine housing or adding a larger wastegate?

Well, i guess we can get technical, yes, I do plan on porting the exhaust housings a little, but not much, and I have an external I planned on using (60mm), that I could make work, but I don't know just yet, I don't think the external will help me out that much in the end. The t2 flange can produce that much hp easily, gt30's come in a t2 flange option aswell, and that would be way over 400.

edit// plus I have a fully built ka// so 400 will be no problem.

ok well in my opinion (and i have never used a t2) i think the 60mm will help tons. and ya i have heard that the gt30's come in t2.. insane lol but the fully build doesnt do much for you power wise because you lower the compression. you said you got supertech valves which if they are bigger than, yes it will help power. and if you got bigger valves then im hoping you ported and polished the head. and maybe you have turbo grind cams so that would help too. but i just dont see it being easy to make 400-450 on a t2. but again i could be completely wrong. good luck and im excited to see some dyno charts with boost psi.

feel free to school me anytime also lol

Haha, well I'll decide on the 60mm later on once I have the manifold in my hands again and such, and yes, I have larger valves and port/polish. I'll have the dyno charts up but not soon, i'm waiting on the motor to get back from the machine shop(again), so i can get it in my s14 and mock everything up, then take it back out and getting everything painted and powder coated, THEN dyno.
