I'm not saying it wont work, because clearly it does, but its just excessive unless your running 15+ psi.. Subaru put that on a 2L motor running 1bar for a reason. If they had a 1.3L engine, I can assure you they would use a smaller turbo. Lol Fair enough, your in a shitty mood and I'm being stubborn :) Feel free to chime out, and I thank you for your help up to now :bash: PS: If you look above the photo, I said its a TD04-H because I couldn't find my L map. At 6000 rpm, a 1.3L motor only pumps out 65L per second (0.065M^3 per second).. (assuming your pumping 65L per second at 6000rpm, which given the age of the head design and the cam profile, I highly doubt.) 7psi is a pressure ratio of about 1.47 6psi is around 1.4

Alot being? I appreciate that, but I am telling you that the WRX turbo is too bit for that motor. Not necessarly lag wise, but efficiency wise. Have a look at the compressor maps and you will see why. The map I have is for a TD04-H, only because I can't find my TD04-L one. That was mapped for my old impreza RS 2.5L at 7 and 9psi from memory. Will have another look through your page, I'm more interested in suspension, brakes and gearbox/diff stuff now :bash:

Will do :) Scouring Ebay now :) Suckthrough is cheaper and well I don't need an inter-cooler at 7psi. 1.5 will be plenty, the inlet to the turbo is just under 1.5" Because WRX seats go for around $200 anywho. I used to have a impreza, and they were fantastic. Simple, light and supportive. So will the AE86 mcpherson strut bolt up alright? (front and rear) I'm assuming the coilover kits are just strut inserts and springs, please clarify :bash: Id like to do lsd from the start, if I could.

Well I need to decide if I want blow through or suck through. I'm not opposed to redesigning the intake manifold, 90degree turns suck balls. Suckthrough: Pro: No need for upgrade fuel pump don't have to house the carby. Will look neater. probably cheaper Cons: can't run an inter-cooler, limited in boost pressure because of that. Blowthrough: Pro: Can use the standard inlet manifold Can use an inter-cooler. Cons: Will have to upgrade fuel pump Will have to encase carby (or replace, apparently needle and seat don't like more than 5psi) More money I would have liked an inter-cooler, but then again I will only be running 5-7psi. Maybe run blow-through later if I upgrade the carby. The CT9 will do just fine, its setup for 7psi on a 1.3L stock anywho, so thats perfect. A TD04-L is too big for a 1.3L, I looked at the compressor maps for my old impreza RS 2.5 and that just made it into the efficiency maps at 7psi. I can't find a map for the CT9, but I'm sure its better than a wrx turbo ment for a 2L running 1bar. The CT9 is capable of around 13psi and thats more than what I need, the engine will die at around 10 (so I'm told) For suckthrough, am I better off replacing the carby now? Ill have some money left over considering I don't have to buy an IC. Finding something from say a 2L motor (Theoretical capacity at 7psi) 1.3L=14.7 (atmo) x.xL=21.7 (atmo + 7psi) = 1.91L motor.

Ok, this isnt another 'I'm thinking of going down this path' thread.. Basicly, iv got a 84 rolla (I think its a KE71) and I plan to strip it to bits and track it. I'm going to strip pretty much everything, aside from the drive-train. I'm going to turbo-charge the stock motor and use that untill it dies. This isnt a daily drive, so it can sit around for as long as I need :) Just wanted a few pointers for the build in certain areas.. I will be running a blow through setup on the stock carby (if possible, may have to get one from a 2.5L+ motor), and will have to encase it to prevent fuel going out the bowl. The turbo Ill use is a CT9 from a starlet GT (1.3L turbo) stock is 7psi on that car, and thats more than enough for what I want. This will be running through a factory XR6 Turbo inter-cooler (it only has about 1-3psi pressure loss on the falcon, so little to none on this car) My concerns are about the fuel pump, and where to tap the oil lines.. Whats the standard mechanical pump rated at, 5psi? meaning I can't run my desired 7-8psi. Ill chuck in some standard WRX seats, not sure what todo with the dash.. its just extra weight, but less work than making a new one. I will definitely need to address suspension and possibly the rear diff.. I could either weld up the stocker, or somehow find a LSD (or just swap out the diff entirely for like a hilux diff) Anybody want to chime in here? Thanks guys
