correction, it's the infamous strawberry mr. aaroncake argued endlessly would have no ill performance aspects on the other forum... man that was a funny thread.

yeah for the effort he could have done a full t04 manifold, and had a turbo that didnt suck

heh cherry what was I thinking. Anyhow If you want a high compression motor you should just build a t2 motor with n/a rotors..

What if i got the turbo manifold, turbo, turbo controller and harness from an S4 t2 and put it in an S4N/a?

KompressorLOgic

well i just did a NA turbo setup, using 6 port block, port matched s4 t2 manifolds, an s5 turbo, and s4 turbo electroincs, ecu, injectors, afm, pressure sensor. i modified the NA harness to work with the t2 ecu,



BTW im runnin an rtek1.7 with 720cc secondary injectors, walbro 255 pump, and a SAFC, havnt "tuned it yet" but its running fine.



heres some pics , althought this is a questionable setup for oil feeds/ return, my gauge and oil level sender didnt work anyway

taped into the stock pressure sender, then drain is into the oil level sender. and im goign to be using an aftermarket gauge anyway... wiring was allready cut when i bought hte car so i just spliced it back together, lengthening the TPS and BAC was requirted.



starting the port matching processor matching a 4 port man to a 6 port block







some of the oil return and pressur line stuff..



oil drain





opps skiped a head ab it almost done





runs great is alot faster then before even running stock boost for now... with safc set to 17% rich for "safty" till i get the wide band installed...

Turbo a N/A engine waste of time. Rotors chamber is not right. Swap the engine for a complete turbo engine.

what would be the advantage of a t2 with na rotors? mazda must have built them the way they did for a reason

KompressorLOgic

na rotors are higher compression, higher compression= more hp per psi.....



however go to high with compression and detonation can be an issue, s4 t2 is 8.5:1, s5 t2 and FD are 9.0:1



but the na 9.4 rotors arnt THAT high of compression really...





well my NA turbo just dynoed 231HP and 220 ft lbs at 10 psi. and keep in mind this is a NA block with 200K miles haha

The higher compression rotors also get you into boost faster - isn't J-rat putting down over 500 hp on a turbo'd NA? Admittedly, I think he's learned a couple of things the hard way. If you're not intending to go nuts, I don't see where there's a problem, correctly tuned.



You said you tuned for 17% rich until you got the wideband - is that 17% rich across the board, low and high throttle? What are you doing injector-wise? I'm wrapping up my turbo'd NA project soon, and it really didn't cost that much to do it, but I'm trying to collect what info I can.

Also, the distributor has to be modified to lock out too much advance. I am 90% done with my turbo'd N/A.



I need help figuring out this mysterious MSD 3 coil set up. I am running 2 MSD 6al's and a Haltech F9, which is a fuel injection computer. i was told I need to run 3 coils with this set up, but I am still searching for more info.



My set up is in a track only car, with fuel cell, large pumps, etc. I weld/grinded the T2 lower manifold, larger secondaries, S5 T2 ex. mani, S5 turbo, oil feed from oil pedistal and welded a small inlet into the oil pan for return, water circulating with feed and returns welded into radiater lines, FMIC, and most importantly, having to run 100+ octane for safety purposes, but I still will when I go S5 T2 motor.



A small problem was the throttle cable fab work. The N/A one is real short!
