Ok.... there is a chance that i will be rebuilding my engine very soon... a small chance but its still there... anyway i would get the master performance engine kit from howell automotive (10.5 compresion, .040 over, crane #18 cams, long rod, non forged crank)... what else do i need to purchase with the kit? do i need main and head studs (ARP) or anything else... also if i were to get 12.5 compression would i have to run race gas all the time, i know with 10.5 i have to run 93 which is very doable... any insight from the 420a gods would be helpfull
Thanks!!!!

Read disappointment here (http://forums.2gnt.com/dcboard.php?az=show_topic&forum=4&topic_id=59057&mesg_id=59057&page=)

That dudes probably got 2K in parts and machine work there, and he mustered a silly low 159hp to the wheels. this has convinced me to never go all motor n/a in the 2gnt. should be done. w/ the assistance of nitrous you could get some nice times but w/ the nitrous setup your looking at 2500 bucks between motor and nitrous kit. guess what you could have for just 300 more??? stage 2 star kit. stock compression at 8 psi tuned correctly you'll make 220-230 whp. 60hp for 300 more. o yeah. plus its all the time power, not just when your bottles full. Do a compression check and see what kind of condition your rings are in but even at a really safe 5 psi you'll make more than 159hp, i guarantee that. then when you decide to get real with the car you drop the extra 1500 into the bottom end, the additional 6-700 on the right fuel setup, turn the boost up to 15-16psi and be sitting real pretty. After reading about this kids numbers and seeing what he has done I myself woudlnt' go down what disappointing road. just my opinion buddy, take it for what its worth.

ya.... the only thing holding me back from the turbo is that its been done before. I would love to see my NON turbo high comp motor do something great, but like you pointed out it probably wont happen. im thinking too far ahead anyway all i really need to do is fix the huge leak i have from the real main seal. which, correct me if im wrong, ill have to take the motor apart anyway so i might just get the stock rebuild kit from howell for 350 and go from there.... but i think that you have finally talked me into, or i just finally realized, a turbo kit is the way to go.... should i maybe throw the money into a low comp rebuild now and then get the turbo or do like i said and reubuild stock? yes lots of dumb questions again LOL

EDIT: also where can i find the star kits online?

For your rear main seal Problems (http://columbusdsm.com/forum/viewtopic.php?t=5269)

If it were me i'd start saving for a star stage 2, overboost.com sells them and if you check 2gnt out there are a few more places that do as well. I wouldn't deal with wyatt(the original star kit guy) b/c hes a pain in the ass to deal with. Do the low compression bottom end and boost it. Your valiant try of all motor glory is only being done by 3 2gnt's in the country as of now, and with disappointing results. Your right, you'll be another turbo'd 420, but they aren't all that common. We just happen to have a few here in central columbus. But across the country your talking about probably 50-60 guys. With the thousands of nt's sold your in an elite class. You know i've got the hookup on internals so let me know what you want to do, we can get you a nice eagle/je setup.

dont mean to steal the thread but what is bad about a little high compression...a guy i know got a turbo, biggest one he can get for his car...they told him that when he wants to upgrade to a bigge one that he would have to rebuild and bore over like 20 or so to put a larger one on there....and these ppl have been builing motors and puttin on turbo's for a while and made ppl pull some really good times...reason i ask is im savin for one and i have mine done 20 over...

there isn't anything necessarily wrong with doing high compression and turbo but you really have a small margin of error. higher compression leads to higher temps, turbo leads to higher temps...both causing higher temps means you have to have a very nicely tuned car with less room for newb error. going all motor just isn't getting the types of results that i'd be happy with. At 159whp hes still going to get beat by the faster 4 bangers like preludes and the like and probably only be able to break into the high high 14's w/o any type of spray. its valiant, its pretty rare but its not putting any monster times out. i wouldn't go down that road, but its must my opinion

some tips with turbo either low or high compression between 9:1 to 12:1. i think 10:1 with turbo would be great for a street car.

low compression
- more timing
- more boost
- more lag
- less efficient hp
- more room for error

high compression
-less timing
-less boost
-quicker spool
-more efficient power
- requires more precise tuning

without a standalone on this car is a recipt for disaster. 420a ecu = linear timing at wot. bad when theres that smaller margin of error. with the lack of full standalone ecu's for this particular app i'd say stick w/ 8:8:1 + boost and picky back your way into 13's@106+. it works, its easy to tune. no need to be a pioneer using this powerplant

who wants to settle for 13s without a standalone, i sure as hell wouldn't. not trying to start shit but i think it's mandatory for whoever wants to make big hp to run an EMS. either from a full-blown race car to a reliable street car, if you are gonna spend all your money on making mad hp then isn't your engine worth extracting full potential.

its cool, your point is valid. one thing to consider is weither its cost effective for the newb to spend the 1600+ on a standalone plus the extra 200-?? for tuning. thats quite a commitment so i guess it depends on the goals of the owner. It is not needed in a low compression application unless your running silly high boost levels but I will agree its something that would be very nice to have. The amount of 2gnt's in the country running a full standalone unit is countable on one of my hands. The factory ecu along with old school tuning will net very respectable times and power.

I said 13's b/c w/o slicks in this wwd pigglet he will have trouble doing any better. I pull 106+ traps all day so I have the power of a 12 sec car and have pulled 12 sec dsm's right after we left the track. It all comes down to the driver gasket.
