Built for Boost
 

So i know that alot of car manufacturers over engineer their engines to ensure that they last a while. But what are some engines you guys know of that come stock NA and are just ASKING to be put to atleast 10psi ? Is there any stock engines that will handle 10psi every day or would that pressure require modifications ? Thanks in advance for the help.

Also, I know that factory turbo engines are usually pretty mild. How would a factory turbo setup handle a serious turbo application (ie 10-15psi) ?

90-94 nissan sentra se-r motor of a tank, will handle alot of power with no mods.

Re: Built for Boost
 

anything that comes turbo'd is usually pretty strong.

Integra Ls' seem to be reasonably strong. 15 psi worth i'm not too sure. But remember power kills motors, not boost.

i personally like the 2.2 motors from the toyota camry and celica. Friend of mine had one in his celica going strong at 13 #'s of boost and had like 220 whp from it daily :6

I ran 22 psi on a HRC super 20G turbo on the stock bottom end of my talon with no problems at all...

Good engine management and a tune on the dyno , mainly

my 97 hatch.. y7 10lbs with a T25. over a year now. 178K miles on it

Re: Built for Boost
 

there are guys running 500+ hp on the toyota 2jz engine (non turbo) with only an upgraded head gasket and head studs.

those stock blocks that come in cars arent really ment for boost that you guys listed.. i mean cmon look at the rods in the ls... three dinky..i mean they may be bigger than the d series that not a good comparison.. IF you want a solid block thats na.... look for turbo diesel engines that were converted over to be used as gasoline engines. ie.. The jetta vr6 block. not only is there block think but there rods are pretty hefty too. i would also bet most of the quality german made engines are pretty hefty. Like bmw, just lower compression add boost and i bet it would last forever also.

my friends ls had 22 lbs daily driven for like 4 months then it went poop.almost any d series can handle 10 lbs on a small to meduim sized turbo with a good tune. thatswhere its at is teh tune. ive ben runnin 10 to 15 lbs on my d16y8 with a 48 60 t3 now for about 3 months on a base map that runs real rich. just seein how far i can push it cuz i got back ups in the mail(eagle rods new srp pistons blah blah blah) and its stock all the way cept for exhaust.

bmw str8 6 is the "the german RB26" my father had a 99' M3 coupe with a mossleman turbo kit, it ran for 3 years no problems and smoked the doors off many porsches etc. damn i miss that car

Re: Built for Boost
 

I like the 4G63 engines. with those cast iron blocks, they're like tanks, cant destroy em.

Re: Built for Boost
 

the 1990 bmw 318is motor has forged rods stock.

Re: Built for Boost
 

:y

Is the rumor true that "most" (say like.. 1990 and above, im not sure) Nissan engines have forged rods, pistons and crank?

Re: Built for Boost
 

I've heard that but never had any experience with nissan really. I swapped an SR20 into a 240 but never opened up the motor. I do know that the RB series (skyline motor) they tested the factory internals/block and it with held all the boost nissan could throw at it. basically indestructable.

Re: Built for Boost
 

BMW can handles lots of boost, stock turbo M3 can handle about 600whp stock. D series is indestructible even at its limit, oh and nissan's ka24 can handle 300whp + with good/decent tunning (forged rodas and crank).

Re: Built for Boost
 

my dads M3 made 468 on all stock internals and aftermarket headgasket.

Re: Built for Boost
 

ive had my accords stock 135k mile A20A3 engine to 13psi with spikes to 16-17psi on pump gas over 2 seasons, ive had it boosted for nearly 3 years though. I recently lost the engine due to bearing carnage but other than that the compression is 175psi across the board.

Re: Built for Boost
 

Umm, maybe you haven't actually looked at the specs on an S54 motor. 11.5:1 SCR is boost friendly? I didn't know that. Maybe you know more about them than I do, but there is a jet black E46 m3 vert sitting in the garage. And there are few (if any) boosted E46 m3's making over 500whp, let alone 600. I am just wondering where you found a boosted S54 making 600whp on a stock motor. Don't post garbage, some people may believe you.

Unless you crank walk, or have anything other than the 6 bolt bottom to try and make serious power. Then they explode very nicely :P

Re: Built for Boost
 

If memory serves me right the vr4 '88 RS model came with forged pistons.
But yea the 4g63 is one hory sounding machine 8)
