Our engines do not need to accelerate past the peak HP which will be something around 5.5 k rpms but the thing is I don't want to improve HP to higher RPMS cause the car will be mainly used in AUTO X and I need more mid power (low boost kick up probably) but we will see , anyway is too much expensive to de stroke it it is better to reinforce the internals (buy some forged pistons and the cyl head I am already working on)

 

bump bump bump...

migue i am currently starting up building my 4g69. and im worried the block wont handle the HP i am aiming for. did you ever figure out if using the 4g63 block with the 4g69 pistons and crank shaft work??? what exactly did u do?

thanks for the help.

He was last online a year ago, I would send him an email if you hadn't already

 

from the gist of it, it looks like he stopped doing it. my question is did he stop doing it cuz its to hard/expensive, or did he not do it cuz its impossible to bore out the 85.00 mm to the 87.00 mm. what made him stop doing it? maybe my mechanic can make it happened.

it would be really nice to have a block that can handle and has beeen proven to handle these levels of HP. our block is finicky as it is, let alone double/triple the HP like im going for.

so whats up with these EVO blocks? i emailed him (i think) so i hope he comes online and checks it out... and it says he was last online dec. 18th of 08. so yea "last year" but only 3 weeks ago lol....

 

he stopped because he is selling the car and has a g35 to play now.....
ill ask him to log on when i see him to answer the question

 

tell him to hit me up too haha i had some questions for him and havnt talked to him in close to like sheesh 2 years.

 

awesome, thanks alot PR mivec.

 

Really, though, why bother with this at all? If you're going to use the 4G63 block, just use the whole damn engine. That said, I really don't think the 4G69 block is that weak, not sure how much power you're going for, but you shouldn't have an issue with 20+ PSI on the block. The Evo X guys aren't yet having any issues, that I've seen, with high pressure on an open deck block, and ours is semi-closed.

 

I agree; but I don't really understand, are you going turbo or NA? 'Cause it seems 2 me you are proposing the two things in this post. If you are staying NA, I dont think the 4g69 block is the issue, it should easily resist, the real issue will be, as thunder is saying, the piston & rods. Power is a function of torque*rpm's, so if you stay NA you can't really increase torque a lot (unless you increase displacement). The only way is to increase rpm's; I'm not shure I would destroke (as thunder sayas) 'cause then you'll loose torque and will have the raise rpm's even more to get the hp's. Now you are aiming at about 105 hp per litter, that is not an impossible task it can be done with an NA, specially if you are looking for forged internals and with the help of the MIVEC system....If you go turbo, you can get that with about 10psi, so you dont have problemns there either.....
I envy you, I sounds like a really great projetct!!!! congrats

 

not going NA. im already turbo. already at about 11 psi. my plan is to bulletproof this motor and get 509 whp or more with a bigger turbo. I just dont think the 4g69 block will hold, so i was wondering if this guy used an evo block or not. wanna know what he did.

 

Therez nothing like boost...srry....// but forget determination, once u have money...lolz u can do anything u wantt...

 

Hi there all again , been out for a while from this forum. Quite busy moving ad buying stuff for my house and etc etc . Long story short I bought a G35 and a 96 GST (1G short block on an assembly table now) . Posting the pics....





Ok so as for the Rallliart , I still have the car , tried selling it but the damn political problems in PR are making the economy REALLY sensible and people want to buy cars as if they were Scooters in the Dominican Republic... been there done that.. LoL

So this is what I have in mind..... and my current setup

Polished ported Cylinder head and IM
Injen CAI ceramic coated...
Custom 1-3/4" runners header
2-1/4 Exhaust with HF cat and Magnaflow muffler
UD pulley
Solid mounts


If I an doing this I will turbo my car the right way, apparently the 4G63 block will be too much expensive to modify and therefore it is not worth it. You can either research a little bit and try to swap parts to enforce your block. IE

Find if the 4G64 crank is heavier than the 4G69 and if it works maybe your crank is too light, destroking the RA and letting it REV higher might solve some wheel spining due to high torque BUT the RA has a single CAM and the gear ratios are not adequate to pull that off. I suggest the following:

Use 4G63 EVO rods
Use 4G69 Wiseco pistons
Port your Cyl Head and have the valvetrain reinforced
Change your Throttle Body to a 2003 Galant one and use a AEM programable computer to activate the MIVEC
Eliminate the EGR
Use a midrange turbine not a High RPM monster a nice T3/T4 turbonetics hybrid will work just fine
Have a camshaft made for midrange power low range quick spool wont work since your car will just spin te wheels
AND MOST IMPORTANT , TRACTION , the AEM I believe has a boost by gear function this will be a good setup for the street.
LSD is a must but I believe you have it already. Bigger rims (17 or 18 maybe) will help but again too much stress to the tranny might break it or break the axles but the Variable boost function might help on this . Again I have tons of ideas but you need to get your goals right and plan for the worst.

 

Ohhh I really missunderstud you. Anyways, 500+ hps!! that a lot. Good luck with your project. Keep posting to update us with your advances

2 questions:
-Which AEM (model number) controls MIVEC? I've been searching and googling and some say it works, others say it doesn't. Can you point me in the right direction?
-Remove the EGR? Are you saying this for Turbo RA's or for NA setup? What would this do?
