wiseco 1400hd available for 4G64 86.5or 87mm bore and 156mm long rods ?

 

they will make you a custom piston boss long as you pay for it LOL

 

^^ Rock - you must have a lot of free time as you seem to post a ton ...Do you have a dyno sheet of your current setup you can post ? You seem to keep making posts about the 2.4 L being better than 2.3L. I think it would be great if we spoke more about some of the 'issues' with 2.4Ls with high boost - sealing issues, cooling, etc.

If all of the 'old' 2.4L issues have been worked out, then great....

 

pm me your number we can talk no sealing issues boss we talk more on phone and 2.3 is good motor

 

yeah but everyone order custom pistons on his 2.4 long rods project ?

 

i think most people order maps rods or go with the manley turbo tuffs in 156mm so the rods are off the shelf parts.

 

i dont know if there is off the shelf pistons for a lr2.4 i know majority will get custom ones to get that compression what they want. Either way same rule applies if you pay they will make

 

Rock - just curious where is your dyno sheet ? No need for a phone call - I'm just looking for more info on longevity and reliability of moderate to high boost 2.4L. I've had several very reputable California engine builders (race shops that build pro motors) advise against the 2.4 route.

I'd be really curious to hear from people that have been running moderate to high boost 2.4L for 40k+ miles.

 

i dont have it but i can get it. not sure if you really wanna see this one because my car will be making way more power it was held back by the soft spring in my Forge MBC. Unless you just want more data to compare for now. Car will be going back to dyno probaly end of january or feburay after JMS moves there shop. There are several of us 2.4 guys now running fine. Think johnnytsi has been running for like 20k. Dont use cosmetic hg and you will not have to worry about leaking lol. Stick to ams custom or power enterprises and all will be fine.

 

Ok so the 2.0 and 2.1 can rev past 9k it seems, but whats a safe rev limit for a built 2.4?

Is it comparable to the stock rev limit or what?

 

8000-8500 for std i would say but then again YOU WILL NOT NEED TO GO THIS HIGH this is exactly what we keep saying you will be making TONS OF POWER and TQ by 7500 or before pending turbo its just plain stupid and pointless to go higher unless your at track or doing it for ***** and giggles

Now i have seen 8000-9000 on a LR2.4 same rules apply but i would feel hella safer doing it on a LR version for sure. Still not required in the slightest.

If you wanna rev to 9k+ your options are pretty much as you stated 2.0 or 2.1 take your pick becuase us 2.4 guys will never require such a thing. What is peoples fascinations with high reving really? on the street really? I understand the drag strip for sure

 

for every 6mm of stroke you add, you lose about 500 rpm worth of safe rev limit. so 1,000 rpm lower than what you feel comfortable revving a 2.0/2.1 to.

 

Ok thats what i thought, thats more then enough and well worth the trade off for drivability in my eyes, just wanted to get it cleared up.

Thanks for the input.

 

I really don't care about drag racing, but the issue is similar. For me, the RPM is critical because it determines how fast you can go in each gear. FWIW, I already feel the gear ratios are rather short for high hp cars and then if you reduce the safe RPM limit you have further hindered your setup (IMHO). I have already spoken to a bunch of folks that have high hp 2.3Ls and they all say the same thing - need taller gears....So if you can run a 2.3L to 8K and a LR2.4 to 9k (and have the right turbo), then the LR2.4 is the optimal choice as long as it holds up comparably to the 2.3L.

 

yes but with maps long rods you also need the custom big bore stroker piston..
without the long rods we lost all of the 4G64 block benefits ?!
