Yeah, those are good choices. I prefer a compressor wheel no larger than a GT35 (61mm) to keep inertia low, but I require a T4 divided exhaust housing making the T67 a decent choice. Get both of these and hybrid them together or look for another turbo already set up like this, like the TD61 or that eBay (fake GT45 thing) listed above.

Hey, "GodSpeed Project" is a vendor here, right? I wonder if we can get a discount on such a hybrid?

 

The td61 is a great turbo to max out at 500rwhp, or go slightly beyond. and it's cheap!
if you don't want 500rwhp, or if 400rwhp is enough, why not twins? fitment would be my only concern, this is for a repu? you sound like you're looking for spool and torque rather then max hp...
i'm bringin the twins back baby. points i will make from my research:
1 spool. 1500-1700rpms
2. no need for FD ECU
3. controllable with vacuum/rpm switches/relays.
4. 400-430rwhp stock? plus there is the bnr upgrades.
5. cheap, until people catch on....

 

Good advice, but two things: Yes the FD twins don't fit very well in a truck, and two, the FD TB and elbow are like right on the brake master cylinder.

So as much as I'd like to do an FD engine, I'd be better off with a T2 or something custom like a projection TB or a blow through carb.

Another turbo option is to try out a stock S5 turbo, which would give me spool and low end like I'm looking for, but it requires a custom tubular manifold. I figure if I'm doing the work anyway, why not go for the bigger turbo like the TD61 you know?

The last option is a Camden supercharger. This option is easy because I have the parts already.

 

Nope. you're still not thinking outside the box far enough, FD twins, on what ever engine port design you want. Fc turbo manifolds fit 13bs from 84 until FD...

i can't wait to see what twins do on this beast of intake/exhaust port area. It's begging for semi-PP. and wait til you see what i do with the exhaust!



I'm sorry guys, but these are the only *TEASER* photos i wanna put up..WAIT til it DYNOS!
Some info: There is a spacer, it's 3/4 inch thick on the top and about 3/8 at the very bottom, close to 1/2 at the lower bolt holes. This spaces, AND rotates the twins down. ALL of the lines are done, ext oil drain, just got my flare kit in yesterday, so the tubing should be wrapped up. then i can run it, and dial setting in. there was abit of tig welding on the intake side to merge the pipes into the maf. running the rtek 2.1... although i have an emange platinum sitting here.... hmmm. the thread title is looking at two turbos, maybe it's your destiny bra.

 

Here are my twins. Probably not useable.

 

probably? check the shaft play... it looks like the rear could be bad, but you can always swap a good chra from a differnt set of twins, you already have a half good set. the front and rear are swappable. For me, the performance/cost outweighed the complexity/time spent.
