I just found a person who could get me a skunk2 chip that can make my RS rev up to 8500rpm safely. Is this possible? my redline in the RS is 6800 and fuel gets cutoff at 7100. Do I need to do anything to the engine to make it rev to 8500rpm? and will it make power there?

Plus, there's this awful sqweak with I go up and down bumps from my drivers seat, any suggestions where this is coming from and how to fix it? if I move up and down on the seat, it'll sqweak.

Thanks

 

well you should get cams, retainers and springs, and even then 8500 isint good for the LS bottom end. 8k max with headwork only.

 

Yeah, atleast on my '96 teg RS there is no power beyond redline. I think you could better for your money at this time.

 

Squeak is probably from your suspension. Try lubing it up. I wouldn't bother to get a Skunk2 chip if your car is bone stock. Money can be spent more efficiently elsewhere.

 

actualy the bottom end can handle the revs. its your head that cant. the springs are too weak to take 8500 for too long. i would wait on the ecu until you can get some springs that can handle that and cams that can utilize that rpm.

 

I don't think its from my suspension because its only from the driver's seat. the none of the other seats make the noise. but if it is from the suspension, where would I start to lube it? i'm trying to sell this car soon and buying another teg maybe a gsr

thanks for all the replies on the chip and seat so far

 

You mean to say that a stock LS block can handle ~1700 more RPM than stock??? NO WAY! It might make it there a few times, but the motor WILL NOT last if you are abusing it like that. Dont say that I didnt warn all of you away from this advice. Stop spreading misinformation!

try checking the seatbelt buckle.. that's where i found my noise at, but i haven't been able to fix it. if you tighten the belt a little it'll stop making noise

 

The LS bottom end willnot take it. You will need stiffer valve springs or you will bend your valves.

 

To strengthen the bottem end look for the Z10 block girdle.. Ive heard good things about it for the LS bottem end.. then build the head and with cams, vavles springs retainers and vtec wont mean ****.. except youll have a nasty chugging idle

At least change the vavle train and get cam because the stock ls ones stop making power way before 8500

 

I'm wondering why a LS bottom end couldn't take it...A GSR's bottom end is safe to at least 8000 rpm, and the pistons are higher compression. What makes the B18B bottom end inadequate for high revving?

 

ok. first to brinks. if a ls block and a gsr block are using the same bearings and the same crankshaft why cant it? its not misinformation. 1fastgsr what proof do you have to back this up?
degradeted has the right idea. when i built my b18b engine i checked with just about everybody i could that has built honda engines for a living. they all say the same thing. the ls bottom end is strong, its the valve springs that cant take it.

 

You also have to factor in the rod to stroke ratio of the LS vs. the GSR... The LS is basically a slightly bored and stroked GSR motor with a weak head.. Its common knowledge that stroker motors increase lowend torque while sacrificing top end.

 

ok dumbasses, here is why a STOCK LS BLOCK cant handle the revs over 8k safely.

- NO oil squirters
- NO girdle
- Rod design

If you rev a STOCK b18b over 8500 for any extended period of time you will **** it up, spin a bearing, or throw the entire motor out of tolerance. And it will flex. Dont try it, with a built head it can handle 8k every now and then, but I would go no higher.

don't the LS and GSR have the same bore? correct me if i'm wrong

 

Yup, that's what it is. I have the same problem but i haven't bothered to try and fix it yet. I thought it was the actual seat at first too but after a month i finally realized it was just the buckle.

 

you are right, my bad.. LS is not any larger bore, just larger stroke..

 

Because there are other differences as stated in the above posts. Not to mention the flow characteristics of the oil and water pumps designed to lubricate and cool at those speeds. Bottom line, the vtec motors were engineered to handle high rpm over 8000, LS motors were not.

Ok, without subjecting ourselves to calling other people dumbasses, why don't we inform each other on how to equip a B18B to handle the high revs?

What is the cost and labor involved in preparing the LS bottom end for 8000 rpm revving, and on a consistent basis? Would adding oil squirters and girdle be sufficient for the bottom end, while installing heavy duty valve springs, retainers, and titanium valves along with this chip be okay for the head? Would one venture to say that a turbocharged B18B would make power beyond it's stock redline without adding more aggressive cams?

 

Lets just say the power gains are not worth the money, dollar for HP, you are better off getting a hondata or something to control the boost better. The higher you rev the higher the chances for detonation, so no its usually not worth it to raise the redline on an LS to 8500.

My seatbelt buckle developed a squeak also... i used lithium grease on it... fixed it.

 

where did you put the grease?

 

yes, where did you buy and place the grease?

thanks

 

ls botom end can rev to 8000 all day fine for a year at least.. the number one problem is associated with the weak rods the LS comes with. While yes, the rod/stroke ratio is lower than a gsr.... the main reason that LS/Vtecs spin rod bearings and throw rods is because of the weakness of the LS rods. GSR rods are MUCH stronger.. ITR rods are EVEN STRONGER. If you upgrade your LS rods to an eagle set... you will be able to rev to 9000 rpm asuming you have upgraded valvetrain.
