So many like to look down on the 4g64 almost as much as my old 420a. Proved the 420a could destroy a 4g63. Now about to do the same with my new 4g64 seeing as to my last one passed on to a better life.LOL. Was wondering though if anyone could tell me rougly how much I can get out of that SOHC head. Last checked the supercharger going on was pumpin a nice 18lbs. Now I dont want to convert to DOHC unless someone gives me low hp numbers for the current head. Any advice as to which head should I go for?
 
What makes me sad is this "if it aint SOLD" it can't be done mentality most people have. I guess I'll be ready this time around with vid and paper. How many of you have even bothered doing it for yourselves. Obviously none. Not my fault I was catching up to overpriced cars. Like I said. I like going up against the odds. Right now the odds are agains me SC my 64 therefore I am only a few steps away from achieving it with a Mini Cooper SC and custom manifold. Remember kids. Laugh now wow later. ( Or was it cry later?).LOL.

I put a LS VTEC head on my GS and it made a load of difference, I was able to even pull on some ferraris i had 600 hp detuned to 400 hp to the front wheels the only place where power should be. I was tuned with hondata and everything.
 
I owned an automatic 98 rs. I just put in a couple things into it like high compression pistons, exhaust system, walbro, etc. Wasn't turbo or anything. You should have seen that bad boy catching up to evo's, sti's and not to mention gs-t's. Gs-t's we're the easiest of the bunch. Never really had it dyno tuned but for some reason my mechanic just though something wasn't right bout that car since day one. I kinda miss it. Now the reason I say looked down on is precisely cause of what you mentioned. I'm always hearing "Oh get a 63. The 64 aint crap compared to it.". Well today I just walked into Norman Evo's Shop down here in PR. I asked him a few questions cause I dnt like jumping into things without a lil knowledge. Whe asked why I wanted to know and told him I was supercharging my spyder at 19psi you should have seen his face. This is a guy who owns a 9 sec Evo. So I kinda felt like I was on the right track. So I'm lookin for as much knowledge as I can. Any is welcome. I poured many hours into learning about the 420a so I could achive what I did. Trying to cut this time in half. My wife hates having me up all night looking for info.LOL.

I just wasted 2 mins of my life reading this load of crap. When you get done with the eclipse I have a weed eater I want you to build so I can (run) down evo's:banghead::banghead::banghead::banghead::banghead::notgood:
 
.... Ok. Here's one of my motivations for persuing my last project Hahn Racecraft - Automotive Turbosystems
This is where it all began. Now this was all with stock which was what convinced me to better everything then turbo it but crashed it before I could. and this. I found on another site.

"420a standard bore 3.445in

4g63 standard bore 3.350in
.020 over bore 3.370 in
.040 over bore 3.390 in
.060 over bore 3.410 in (still .035in smaller than a stock 420a bore)

my point is, the 4g63 would have to over bore .095 in to match the bore of the 420a. Everyone that has ever built an engine from 4 cyl to V8 knows that a bigger bore means it is that much easier to make power."

Sounds like you're one of the more worth listening to types. Well so far I've been told to swap the head to a 63's but I would like to keep the original unless I see I ain't getting enough out of it. I just dont know how it'll perform at high speeds. It's 3 hr ride to Cabo Rojo and most of it is straight so thats where most of the races take place.

Being the owner of a 97 galant 4g64 SOHC i can tell you that you can make decent power with a SOHC for next to nothing. I ported and polished my head with a dremel, removed the balance shafts from the block, 1g 60mm throttle body, lightweight flywheel and that was it. No exhaust work and i ran a 10.34 my first time at the 1/8 track with that setup. That was all motor. Before i did anything to it i ran a 12.64. Now that im boosted IDK what the power gain is. I havent pushed it to the limit yet. PPL looked down upon the galant until i surprised the shit out of them with what i had when i was N/A. I could keep up with stock GT mustangs and i could have probably kept up with a stock DSM. I know that srt4's and dsm's run 10.50's in the 8th mile and ive seen them run that consistently and more than one of each car. However the galant is lighter and does have better gear ratios than the dsm tranny for take off.

Show me a 420a that comes close to brent rau or john shep........ Not going to happen.

For the first part I really find it useful and great. The second part well not really interested in cause the problem is I don't own that car anymore for 1 and 2 I was just trying to prove people were wrong about the rs. Now I'm feeling motivated by your 2 sec drop. I'll stick to it for now. Anyone heard or a MIVEC swap for us?

Is this the supercharger your throwing on there eh? Is there Chevrolet engine going to go with it?


Take some pictures of this one off supercharger you have for the 64. Certainly thats possible.

You should swap out the soda cans in the 64 for some slugs. Maybe 63 rods and have an engine that can handle 19psi with more than 1* of timing. If you hit a stock 64 with 19psi it is not a question of "if" it will go kaboom, its "when"
 
Unique is cool... looking to cause an uproar of laughter is priceless... I ROFL'ed on this one...

MIVEC is possible on the 4g64, but it is in its infancy for one, and two, it puts all the components on the opposite sides (IE the timing and tranny is reversed... aka wont work...). If you dont know, use the search button for a while and learn... and Im sorry my friend but as you said, your just the money... you DON'T know, so go start using the search button...

Better yet, please do us all a favor, get outta the dsm game and find yourself a honda or something.... a gs running down evos and stis isn't going to happen anytime soon without a 4g swap and an aggressive one at that...

Uhu. Wow. You are a bright one. I just got a 64. I did a lot with my 420a. I guess only time will tell now huh. Tell you what. Keep in touch. Want to prove how dumb your comment was.
 
You 4G guys are lucky:hellyeah:
My 420 can only run the Gallow 12's and are always thirsty for more powerROFL
:banghead::banghead::banghead:

Just wanted to say something about my own previous comment. Maybe i am just dumb but i could have swore you were using a 2F&2F line about the Gallow 24. Given where my statement came from. Correct me if i am wrong.

Nah I got past that part. I'm actually wanting to know in terms of the head combination. I'm not trying to spend too much time researching again. I've heard good bout the 64 head but just want to know how much modding can be done to it.

I ain't even catch on to that one.ROFL

Thats what it came down to for me going from a built big turbo 420a to a near stock awd 63. Aftermarket support. If you can find the parts to mod it for a resonable price then keep the 64 head. You can get lifters, regrinds, and studs cheap for the 63 and it comes with huge ports. Are the intake patterns the same? Can you make the SC work on the dual cam head? A tiny charger from a minicoop will be working very hard @19psi on a 2.4 being it was made for a 1.6 sohc.
 
I am going to step out on a limb here, and say you own several "wolf howling at the moon" t-shirts.

Im game, show me the money... better yet show me the receipts and the dyno slip with pics of the car finished...

As for your comment, what does that even mean, "I just got the 64. I did a lot with my 420a." As the others stated, the record holder n/t was like what, 230whp? And if you didn't catch it, I did infact answer the only real question you have had so far... THE MIVEC WONT WORK in a eclipse...:aha: :rolleyes: :ohdamn:

Like I said post pics of your finished creation... I look forward to it!
 
The only time I've ever, and I repeat EVER seen a stock Non Turbo DSM pull on a Turbo one was when my 12:1 Compression N/T 4G63 was running.....and it only pulled on a Bone Stock TSI FWD...and once again just barely. Once the Turbo hits boost your Toast. Granted you can outrun SOHC Hondas all day long.....that Chrysler 420a was and ugly stepchild that most people just wanted to Beat. Also The Supercharger....I looked when i first got into DSM's and....I hope you have really really really DEEP pockets, but on a helpful note there is a guy that SC'ed a 4G63 in a Galant on here i think he was out of Australia...and he MIGHT be able to give you some pointers. I say look Him up because the 4G6- Platforms are for the most part the same they use the same Mitsubishi Sirius engine Platform...but im pretty sure he abandoned that idea a long time ago its just not practical......unless you have deep enough pockets to build some sort of Supercharged Turbocharged beast like the Scion TC Gojira project, and if your gonna do that........well...Have I seen you on one of those Speed Network Horsepower shows before??? :rolleyes:

:EDIT: Learn from my mistake, I tried being Unique and building a High Compression Beast that I wanted to Supercharge and be different....4 Years and 8,000$ Later....I have a 4G63 in a 95 Shell Turbo'd that I'm Still Trying to Finish. When If I had Listened I might be running 10's Now..... >.>

The people doing the work on it said it will work with the 63 head too with some minor adjustments. The charger was actually sent to BMW for the custom work so I guess it'll backed up by they're warranty.

When did BMW start doing custom work on superchargers? Also how do you expect that a BMW supercharger will fit on something made by mitsubishi?
