What are the HP goals with this setup? Looks like its gonna be a sweet e21, but arnt 30lb injectors a little small? Most similar setups I see are running something a little bigger like 42s

And details on that air to water setup,do you guys sell them or is it one off for this project?

Amazing, looking forward to a finished result.

damn thats nice.

[James Crivellone]

That is really quality work and its nice to see that stuff come out of you guys. The shop race car and other projects that are pure show really give me the wrong message, however seeing clean well thought out stuff like this (That looks factory) really impresses me.

Nice work.

Looking good boys! Going to need a ride in this one for sure. :D

[JoshWho_e21]

Eric should really be pleased to see some progress on this thing. I'm glad he took it to you guys to get the ultimate treatment it deserves. Nice work fellas.

He's gonna hate having that 3.91 with boost, why not opt for a lower diff? Also 30lb injectors is gonna be pretty high duty cycle at 15psi.

DAT BOX.

had me fooled, at first I thought it was some oddly place IC, but now i'm thinking a strange intake?
please explain...intriguing...

[MF DOOM]

air to wa wa cooler. Love the placement.


I also wonder about that 3.91. But is the 323 gearbox the same ratios as teh g260? I saw this on instagram and i liked it

[MR 325]

I'm no E21 guy myself but I know the diff selection is very limited with those cars.

Interested in seeing how this one turns out, Fab work looks great so far.

Looks like an air to water heat exchanger but looks like it does not have the end tanks/plates welded on for the water feed/return yet. It will have water pumped through it and then the water will have its own cooler in the front and will be cooled from airflow of the car moving. You can also add another tank in the system that you can add ice to cool the water/intake air temps even more.

That diff is going to be working for a living !
