Which turbo would you suggest for a 1.8L miata?
 

I know I'm not a noob, but I suck at turbo math :/

Just wanted to get some opinions before I buy. Im interested in doing a 1.8 Turbo. I havent purchased the car yet but I'm weird and want to have all the turbo junk waiting so I can boost it immediatly.

Choices are:
a) T3 .42/.48
b) T3 .60/.63

I want to do about 250rwhp at the track, ~200-200 daily. The car will be converted to MAP (MS&S) and running 450cc injectors.

Should the .42/.48 suffice for 250rwhp? Or should I go with the larger .60/.63?

Thanks in advance for any help from knowledgeable turbo-gurus

The .42/.48 would be fun to drive and spool quick as ----, but I don't think that it will make 250 hp... I could be wrong though seeing as I have never driven a miata in my life.

I would totally use the .60/.63 over that little turbo any day. I don't like to boost at part throttle and I like a little lag. ---- it probably wouldn't even be that laggy.

That's kinda what I was thinking. Think i might go fer one of dem 63's in the classifieds. Thanks man :6

a straight t3 would do but they dont call the t3/t4 the miracle turbo for hondas just for fun. a honda is 1.8 as well. im sure you could get away with a straight t3 63/60 but a t3t4 would do its justice just fine.

I've got a t3/t4 sitting around that I'm supposed to sell to a friend of mine. I feel bad indian-selling it becaues I kinda already promised it to him. Plus im selling it for $400 and I can pick up a straight t3 for $200, thus making $200 which I can spend on other stuff.

I'm going to use a combination of smiles to show my current emotional status on the issue:
:D ??? :( :-\ :3 8) :S :4

haha that'll work jess. make 200 out of it for other ----. jus hope your kit works out better then this local kid. he hada 98 miata with the greddy kit on it. he got a whopping 12hp out of the 3,000 dollar kit at like 6psi. some ---- like that. i remember they dyno'd it before. put the kit, dyno'd after and that's all it got. mighta been more like 20hp at 6psi but either way that would suck cock for the troubles.

sounds like the kit had a leak somewhere causing it to loose power. i saw an eclipse at the dyno pushing 25psi dyno only 180hp cause it was missing a gasket in the turbo outlet.

i didnt say his kit was perfect, i was jus saying hope his works out better lol. i kno jess knows what he's doing. he did jus have almost a 300hp KA torque monster running 13's in a 240sx tuna boat. im not doubting him in any way. just givin a heads up on one that i saw.

The greddy kits suck ass. No FMIC, and an FMU. A friend of mine bought a car with the kit already on it and said it was piss slow. Im kinda debating on keeping the t3/t4. I'll see how my buddy takes the news.

Think I changed my mind for good. Gonna hold onto the t3/t4 8)
