I have just ordered an FP Red for my IX MR. I have the below listed power mods. How much of a bottleneck is the HFC, stock intake manifold, stock head (and springs) and stock ignition? For now, I'm just getting tuned for 93 oct. Later, I will add alcohol injection...

Ported and coated O2 housing and exhaust manifold
Buschur TBE w/HFC
Perrin Intake
Cosworth Cams
Exedy Twin
PTE 1000cc Injectors
AMS IC & Pipes

Thanks to all in advance.

 

sounds like a great mod list, but to get the most out of the turbo,

valvetrain to rev with the powerband
test pipe
02 housing wastegate dump
port match the intake mani and throttle body

with all that on meth tuned, your looking at an easy high 400whp, and depending on the tuner and dyno you may even hit low 500's with an aggressive tune

 

id get a buschur coated/ported exhaust manifold also. i'm doing a red also. i just picked up the shearer o2 dump, and i want to see how it does on the dyno. i've heard they suck and they are awesome. i guess ill find out.

 

I've got a ported and coated exhaust manifold. I'm considering a MILSPEC HFC and MAPerformance ported stock intake manifold (rev2 or 3)... Later, with the Aquamist setup, I might add a Shearer exhaust manifold. You know how it is, you're never quite finished...

 

You sir have a great taste in mods. Don't sweat the head, IM, and IGN. You'll make great power as you sit.

 

Thanks. I recently had my 60,000 mile service done along with my clutch and was talked into the Red. I really wasn't planning on touching the car until next Spring, but a conversation with the guys at the shop about the relative merits of the BBK Full and FP Red twisted my arm (and thus I twisted my wife's arm, figuratively)... Now I'm just trying to make sure I'm not half stepping...

 

half steeping is the worse thing i think you can do... if your going to do it all out one shot ive mad that mistake before

 

i would just go with a test pipe. its just going to rob hp.

 

like said befor, nice mod list. if you wanted to top it off with a ported/ match exhaust ports and mani, couldnt hurt with spool time. could also toss some springs in the head, along with new head gasket and timing belt, and arp head studs while your there. your going to have to do the timing sooner or later.

i know thats a couple $100 list but. that would top off what your trying to do.
GL!!

 

When I got the 60,000 mile service, my belts were changed along with my head gasket, so I'm good to go on those fronts. Also, I forgot to mention I already have ARP headstuds and a Whinebro...

 

Are you on the stock FMIC??? If so, you'll need to upgrade that for sure with the Red if you plan on running a decent amount of boost (and you want to make power). The stock FMIC is fine for the stock turbo on relatively low boost, but can get heat soaked fairly quickly.

Good luck

 

No, AMS IC and Pipes...

 

i would recommend springs and retainers as well. might as well if you want to get the most out of the high powerband and the cams. better safe now. nice mod list you will love the new found power with the red

 

Agreed. He might already have springs though

 

he still has stock springs.

the mil.spec cat is a quality unit, i still made decent power with it. so if you really want to keep a cat (noise, smell, whatever), id get that...otherwise, buy a test pipe
