WOW ... From GT40 heads to now talking Turbo
This thread has been interesting so I thought I'd join in on the fun
I gotta agree with others about OEM or GT 40 stuff not making the power of Aftermarket stuff
It just won’t move the same amount of air
I’m really big into a long term plan for combos
AND
You can easily see others results who’ve gone down the same road you are considering
Having said that …….
Here is what I’ve seen from being on these boards for years and doing OEM/Aftermarket combos
With a focus on OEM short block and staying NA
OEM Stuff
245-275 SAE RWHP
You see a lot of low numbers with these combos because ………….
They’re usually budget minded therefore …
They’re don’t have ALL supporting parts needed
They don’t have a good mix of parts that work well together
Lots of times they’re a first attempt effort so little experience and knowledge is applied
These combos don’t get optimized as they usually have no tune
You can sum it up by looking at what Ford did with the Cobra using the very same parts
NOW … You stress a budget build is needed
SO … I’d say you are on the right track about getting into it on the cheap
That way … If you get bitten hard by the HP BUG … AND YOU WILL
You can get out of OEM for little or no loss and step up to more HP with Aftermarket stuff
AFTERMARKET Stuff
Only about 10 to 15% more power than OEM
Also … the cost is Way More than 10 to 15%
BEST HP BANG FOR THE BUCK SPENT
Mix OEM stuff with a blower
Look at just a couple of the advantages of this method of building such a combo
You can get started with the cheap OEM stuff
1 When you want to step up to more power ……..
The main parts you already have can be used
also
You’d not wanna move to Aftermarket stuff AND blower as the block is too weak anyway
2 You’ll gain MUCH more power this way as opposed to an Aftermarket NA combo
It needs to be said such a combo is not without compromises
Then again … ANY combo that makes significantly more power has that to deal with
A few final thoughts about NA combos
OEM ignition is more than adequate if it is working as it should
With OEM stuff you want to use long runner upper intake for good low/mid range torque
With Aftermarket stuff I like a mid length runner for stronger upper end
These intakes will be softer on the low end
BUT
You can make up for it in the tune and header choice (Long Tubes)
Speaking of header choice … LT’s … No matter if using OEM or Aftermarket stuff
They make significantly more torque down now and at midrange :Word:
Last topic … I promise
I don’t particularly care for the Steeda 19 as it has shown to be soft on the low end
Look at what 95 Snozzer did with his cam choice as it has really good looking curves
Just my 2 cents worth
