It all comes down to what your goals are with the car, the purpose of the car, and your budget. If you have a small budget, save your pennies and start eating ramen 3 times a day.



I wonder how much Lee has spent so far on turboing his original 6port N/A motor? And roughly how much power he is looking at? Compare that to an N/A? Your results are right there.

the stock intakes arent that good, porting helps but its like using a toothpick to kill an elephant. the ecu sucks once you mod the thing too.

I'm willing to go either way (trubo or N/A) to get to about 180 FLYWHEEL hp. Just the same level as a stock turbo S4. Like I said my goals are autoX and maybe road racing.

i like TQ so i would go turbo...

like i said, im probably in around 2k, if that.



im pretty sure i got all the stock parts for about 800ish, + or - some, but its not hard to find some deals. i got a lot of it in chunks of parts from people parting and the such.



i already had the safc when i did it, but i found a deal and got a safc2 for only 180.



picked up some 720's for $50.



oil pedastal and some oil cooler hose from summity, like $60



2751 blockoff set $50



picked up a boost/watertemp/oiltemp gauge set for $50



$80 ebay ic core, and $80 ebay piping. Maybe another 50-80 in misc additional couplers.



downpipe and midpipe was $150, already had a catback.



not running a bov, but used ones are cheap, or do the crushed dsm whatever.



wideband was $250, but you could always just get a shop to tune it.



im running a NA TB elbow, so you could do that, or add $100 for a greddy one or like $20 for a stock one.



i still need a clutch, but thats like what, 150-300? ive heard some good things about those $150 xtd six pucks and am learning that way.



so thats under 2k, and with all the little misc **** its probably right about 2k.



and it was easy too. fill in and port the lim to match, make room for the fmic, cut two wires at the ecu plug, and then bolt and plug in everything and youre good to go.



and im atleast around stock tii power, maybe more. stock 8psi + the slightly higher compression. once i get a clutch and tune it better then my rich everywhere tune right now i wanna throw it on a dyno.

dont get a XTD clutch. get a real one ! you will just wind up changing the clutch twice...

i have noting bad to say about the xtd sprung 6 puck it was a good clutch to dd on after the engine swap i replaced it w/ the rb unsprong 6 punk and its not bad

Hers is my take, wether you want to extract as much HP as possible from a NA, or want to go turbo; your best investment will be a stand alone ecu (microtech\haltech\Wolf).



Put your $$$ there, the sky will be your limit aftewards...

Ouch, I ended up replacing the OEM flywheel after a couple of years of using the RB unsprung clutch disk https://www.nopistons.com/forums/pub..._DIR#>/sad.gif

Is Tweakit the only one that makes individual throttle bodies for 13b?
