Thread: TVS swap?

So have a tune for the e85 on the 42lb injectors and have a tune for the 93 on 42lb injectors?

I aggree, especially if it lets me run a 3.2/3 pulley

Snowflake which model TVS did you use? Was it the 1320 or the 1900?

I used the 1320 from the Cobalts.

i thought the cobalts used a m60

do the SD headers require welding to install?

Thanks! man im happy now, the price for my next set of mods dropped about $200

Wouldn't the 1900 be a better match for the 3800?

I was wondering, if the ratio is off slightly between the increase in fuel needed with e85, and the increase with the injectors, wont the car run lean/rich? or in that range would the o2 sensor be able to compensate?

The 1900 would work mint on a car that was a full blown build.
Stage 4+ heads, custom huge cam, e85, etc...

TVS comes stock on a 5.8 gt500 and they can be had for under 1500, why people havnt tried to use one baffles me.

I do agree if someone was dead set on doing a blower build it would be S3/S4 heads, S3/S4 cam TVS take off from a new 5.8 trinity engine in the gt500s.
I don't know the size of that blower though. And even on that type mega build I would still not intercool it, Im just not a fan of a IC on a SC build.

That would be a monster blower build if planned out properly and of course feed it E85!

Now if that would be doable for less than the cost of a turbo build would be up for debate, however Im certain it would be badass!!

At the end of the day no matter what route taken COST is always a factor.
