Hey, New to the board,
Have an 89 Merkur XR4TI With a few mods.

Holset hx35w running 17psi,
tial 38mm wastegate,
rfl bov,
custom 4" rotated upper intake,
johnny racecar front mount,
Junk stinger exhaust manifold
3" down pipe,
3" exhaust with 2 hd glass packs,
t-5 tranny

More mods to come..
Megasquirt
Racer Walsh stage 3 cam
dual valve springs
oversized valves
and so on












I'll have more to come

 

That upper intake is sweet. I never understood why anyone would gut and rotate a stock upper when they could make something like that.

What are you doing for management right now? Blow-through VAM?

 

Welcome. I love those cars. What kind of times/power is that car running/making?

 

you need a filter

 

sweet

 

Nice, hard to find any more of those merkurs around. Thats a good motor to work with.

 

****, BTW filters are for -----'s

 

It is really hacked, blow through vam(the small one) and a rising rate fmu. With a wideband i was able to get 12.5 afr @ 17psi

I dont go off roading with my xr, and i have a filter,its great at collecting dust in my garage. The filter i found that fits over my turbo is too restrictive, it kills my spool time.

 

FMU on a turboford! Whatever works, man!

(I don't use a filter, either. )

 

Damn 12.5 is a little lean for 17psi man, good thing
those motors are stout as ----
