[2.4 turbo Hyped]

Hey ive been reading this entire thread and all of you are doing either a g4cs block with a 4g63 head with forged pistons and stuff... Well I noticed Swordfish posted a link to Use our original 4g63 block with the g4cs crank.. This would make it a 2.3L if im correct and then all that would need to be done would be to bore out the block .40 over to get the 2.4L i think... Plus custom Dish pistons to lower the compression.... This way seems cheaper to me just to find a g4cs crank and buy some forged dish pistons to get the compression ratio at 8.7:1 or 9:1.... why isnt anybody going this route??? is there anything wrong besides the fact that you have to machine a bit of the block and bridges of the 4g63 for the rods to clear them????? Let me know becuase i was planning on going this route seeing that already have a g4cs crank and 2 extra 6bolt 4g63 short blocks laying around...

Read the title of the thread. You can go that route but you will no longer have a g4cs BLOCK. I started this thread to educate people and make the "rumors" on this site cease and decist. I have built several of these motors and have had nothing but success with them.

how can u tell if its a 100mm crank? i dont know where my crank came from but all i see it say is 4g64 and its a 6bolt? will the machine shop tell me wat size crank it is? i might have read something wrong. the 4g63 is 88mm stroke and the 100mm stroke is 4g64 g64b and gc something. right? im just getting everything straight in my head. im kinda slow

 

[Tongboy]

you're in portland, where do you get a good g4cs block in town for a good price?

I haven't heavily searched but I haven't had any luck either

I have had my g4cs running about 3 weeks now and love it. 9:1 gives great off boost performance. running 10 lbs right now. 1st and 2nd gear do nothing but eat tires 3rd gear pulls like a rapped ape. Getting a tune this weekend, that should make a huge difference, seeing as I am running very rich. would not want to make a guess at power but it would run circles around my 2.0 t25 at 15psi. and I have not had a problem with anything on the streets so far.

one guy asked if it would be good for autocross - it would be very good. torque monster.


I know of 2 4g64 that have walked, I would not build one


anyone interested in info or pricing on a 2.4L:

I got mine right down the street at columbia boulevard auto wreckers. I have bought all of their g4cs blocks (5 of them) . The complete motor was only 275 a piece. They actually end up being free as I sell everything but the bottom end on ebay. Truly a deal if you ask me. Sean

There is no such thing as a 4g64 6 bolt. A 4g64 is a seven bolt crankwalker. The only 100mm stroke 6 bolts that will work for this setup are g4cs and g64b. Please correct me if I am forgetting something. I only work with the g4cs blocks.

 

[djmixerx]

i was mistaken it doesnt say 4g64. all it says is 64. doesnt the earlier galants have a 4g64? like 87-89. thats wat i heard. there only like SOHC.

 

[na90dsm]

there were early 4g64 motors and yes there sohc. deck is easily made to fit the dohc 4g63 head.

not sure which car it came in though.

 

[bigfoot]

I had a question, the g64b block is the wide one right? What tranny bolts to that block? it is rwd right? what all is the same for the 4g63 and the g64b? thanks
P.S. I am wanting the rwd for a project front engine fiero drag car. thanks

You want to put a Japanese motor in the front of an American mid engined car. I like this guy. There are both narrow and wide block G64Bs. There are both narrow and wide block 4G64s, some are 6 bolt and some 7 bolt. Having fun yet? Do a Google search for G64B, 4G64 etc. and get one of the many application lists like these. And carry a tape measure. http://www.remanufactured.com/Mitsubishi_Engines.htm http://www.bestrebuiltengines.com/MITSUBISHI4.htm

There's a place on Marine Drive by the Troutdale Airport called 'rebuilders motor supply' or something similar in the phone book. They had some motors a couple of years ago, cheap too.

 

[Carbonfiberhood]

Ok, I have the G4CS out of the Sonata. It will bolt up to my 2G AWD tranny with no problem right? I've had it for awhile and I just didn't build it because I feared that it wouldn't. I meant to go on DSMTalk, but as we all know the site's been down.
Next question, all I need is the block and the crank, right? So I can sell everything else then and just use parts from my 4G63? It's a 7 bolt. Everything will still work? I am going to be building a 1G head to go with the block just FYI. I am getting antsy over here. I want to start ordering stuff.

early galants had 6 bolt 4g64's in them...

I plan to sell all my spare parts off of my g4cs block on ebay as well. What kind of prices were things going for and what is worth and isn't worth putting on ebay? Thanks

Read the tread. If you use stock 1g or 2g pistons your compresssion ratio will be very high. The stock rods are also a limitation, as they are very weak. If youre going to really utilize the 2.4 (ie 50 or 60 trim...or bigger) the stock rods will break.

 

[Black94TSI]

How high do you think it's safe to turn a G4CS? I'm looking at 8.5:1 JE's, eagle rods, ARP studs throughout the bottom end, and having the motor balanced. Gonna run a big turbo like an SC61 or maybe even a GT4067, so I wanna decide what A/R housing to run. Do you think a .81 A/R housing would be too much? I know a GT4067 .81 A/R will make 14 pounds of boost by about 6000 on a 1.9 litre honda, so I figure it'll be in the 4500-5000 range on a 2.4?

 

[coltboostin]

The g64b block found in the expo vans and the mighty max pickup is set up for a rear wheel drive style transmission. The bell housing on the engine block is too wide for a 4g63 transmission. Is it possible to modify the block to make it work? The answer to this question is yes, but you will have to drill and tap new holes for the dowel pins and bolt holes on the block. It would be much simpler to start with the correct block rather than modify the g64b.

If you have the mechanical skill to tackle a 2.4l stroker, then this sould be cakework. It is worth it since these motors are not easy to find.

It all depends on how much boost you want to run, the higher the compression ratio the less boost you will be able to (safely) run. There are tradeoffs for each one, and benefits as well. With higher compression you have a higher chance of knock (knock= http://www.jandssafeguard.com/tech.html ), forcing you to use higher octane fuel to prevent the increased chance of knock. But the higher compression will spool the turbo faster. Basically, you have to weigh out what you want more. I think 9.0:1 is the general acceptance of a compression limit. 8.0:1 or 8.5:1 is a good low compression ratio.

There are many arguments to use lower or higher compression ratios. The general consensus is that lower compression ratio's will be easier to tune/work with, but a higher compression ratio would yield the most effective results (yet would be harder to tune....tradeoffs).

I hope I helped out.

In order to get 2.3L out of the 4G63/2.4L combo, you need to bore the block .040". Otherwise you only have a 2.270cc motor. Boring it out .040" gives you 2378cc.

 

[2.4 turbo Hyped]

Id like to know how you figure a higher compression spools the turbo faster. Thats news to me. Sean

it doesnt. i think where this comes from is the car feels stronger off boost and leading up to full boost because of the higher compression. note to 2.4 turbo, i dropped my block and rods and pistons off at the machine shop yesterday. i should have it back within a month. all i have to buy is a new oil pump case, cams, and the sprockets and gaskets and im ready.

Are you documenting the buildup with a digital camera?? It helps to have the pictures handy when no one believes you have a 2.4 liter motor in there.

, i dont want anyone to know. besides i can just show them the 2.4 mark on the block.

Its really hard to see once you get a big honkin turbo on it. Go :laugh: od luck finding mine.

1) Will the 4g64 crank work in the g4cs block?

2) Is anyone running oil squirters in their 2.4l?

3) Head gasket selection worries me. Are there any metal head gasket options for the 2.4l block? Mitsu/Cometic/HKS???

4) 6 bolt 2.0l flyhweel/clutch will bolt up w/o any issues correct?

I did not put the oil squirters in my g4cs. I have the engine in the car but need to finish connecting everything before I can run it, and I don't anticipate any problems without the oil squirters. I used a Cometic metal head gasket with my buildup. Yes, they are available with the correct bore. The 6 bolt flywheel and clutch work fine, with no issues. Just be sure to remove the automatic transmission bushing from the end of your crankshaft, if you have one in there.

1) Yes, I put a factory fresh new Mitsu crank in my g4cs block.

2) Nope.

3) Cometic sells a variety of thinknesses for the 87mm bore.

4) Yes.
