SexualRob, why did you choose the strup headers? price or reviews?

 

price, I got them for around 200 bucks off ebay and they looked almost new. plus they were coated already so it saved me some cash. they look really good compared to a lot of the cheaper headers Ive seen. I know they arn't the best performing but I couldn't pass on it for that price.

 

From what I've read and seen, the Strup, Megan, Ichiba, Topspeed and a few others are DC Sport clones, so its safe to say the they all have the same design so they should all perform and sound the same? I know Tomei, Crawford and Nismo are the best but they are overly expensive.

 

strup and DC are clones. I've seen stillen, megan, and topspeed in person and they are a little different, collectors didn't look as nice either.

crawford were supposed to be good but I don't think I've seen hard evidence of that.

nismo look good too but they are expensive

tomei are proven to be good when paird up with their cams

 

yeah thats good info. Ive heard a G with full stillen exhaust, headers, hfc's and catback and it sounded like a honda, thats kinda why I was against headers for so long. But I guess its just the combination of parts together. the megans seem to be cheapest and similar to the DC/Strups so I'll look into those maybe

 

honestly the topspeed looked better than megans to me in person. I would get them for the price. topspeed is right around to corner from me so I checked them out when I was there.

 

Topspeed huh? ill look it. theyre really cheaper. There are a bunch of knock offs on ebay for under $60 but theres no brand and the price itself is reason to be alarmed.

 

yeah, I know... as long as the topspeed stuff on ebay is the same stuff I saw in person you'll be alright. I was very surprised by the quality of it since I also thought they were a knock off brand.

 

those ebay knockoffs look good in the photos and seem legit on specs but its uncertain that they are as advertised. The ceramic coated ones look great but they could be just sprayed matte black

 

Ok, im back with one more decision to make still... Cams. I dont know too much about cams but i understand the gist of them. I'm leaning more towards the S7R's but I recently read about Cosworths ZK1 Cams for the Revup, anyone else heard of these cams?
Specs:
Intake Cams "268" deg. 10.4mm lift
Exhaust Cams "268" deg. 9.5mm lift

I only plan on raising the redline to 8k but will never shift that far. I see alot of guys who get cams go big, but their idle is roughand their powerbands shift to the top to get power. I want to keep my low-end/ mid-range where its at, i want just a little more power past 7.2k where the stock cams fall off. I know I have to sacrifice but this is kinda what Im looking for out of my setup.

Anyone have suggestions?

 

bump

 

Honestly, I wouldn't consider anything BUT JWT cams in my build.

 

yeah i went ahead and bit the bullet and ordered the JWT S7's. cheaper and i trust them more since i havent heard anything negative about them.

 

Subscribed. Interested to see the final numbers. I am going to be building my motor this winter after the race season is over. Your build list is about the same as mine. I was leaning towards the S7's as well. Good luck and can't wait to the see the numbers.

 

Sure man, will do which reminds me.

Update!
2/17/11

I went and got a baseline dyno done to see where Im at now before the build/tuning. Ill post the actual dyno this week sometime.

with my current mods on the car:
Z-tube
Modded OEM Air Box
K&N Filter
MRev2 Manifold
5/16 Plenum Spacer
Bassani True Dual Catback
Kinetix HFC's

I dynoed at 251whp and 232wtq. I wasnt too impressed but you gotta start somewhere

But more updates to come....

 

What kind of dyno?

 

^dynojet

 

Is that baseline dyno typical for those types of mods on a rev up car? I know that mods don't add much but I thought you'd have more than that. No offense, I'm just a little surprised.

 

the numbers seem low and probably due 3 things, and i confirmed them last night after taking off the HFC's:

1) Oil consumption (blow by) loss of power/compression, this was confirmed back in 09

2) Exhaust leak (had a leak at both manifolds due to lose bolts and crooked gaskets

3) Gaskets from HFC's to catback flange where incorrect size, partly blocking exhaust flow, also causing slight rasp.

So these factors are a good reason for the low numbers.

this will ALL be fixed in this build

 

I thought that with your build you fixed the oil consumption problem.

With those 3 problems fixed, what do you predict your power numbers would be with the aforementioned mods?
