ShaunW. · 01-16-2013, 09:51 AM

hey, i'm new on the forum. I have a 1998 240sx . I'm actualy looking for a sr20det for my car. I've found a builded sr20 with stock internal except for the cams. It as:
- gt3076r 0.48 A/R
- emusa external wastegate 38mm
- Enjuku stainless headers equal lenght wrapped
- electronic boost controler blitz SBC (set at 15psi)
- z32 maf
- 740cc hks injectors
- cams tomei 256° 11.5 lift
- JWT tuned ecu
- custom intake
- intercooler 3"

I did search but did not found anything. I would like to know if the stock internals will hold up are blow up. Thx alot!

Kingtal0n strikes again. I really wonder where he gets all those fancy ideas / graphs though.

@op> "emusa something" = dont buy it. emusa is just chinese crap (supposedly they have "quality standards in their USA warehouse", but it looks like every emusa parts i got has not been inspected - or actually has been, and was sold because there was no chance i'd send them back)

Internals dont have a power limit (kind of ... you wont push 1200HP of course), it all goes down to the tune, usage, and rebuild quality. Tight bearing tolerances and a safe mapping will kill your gearbox long before the stock internals give up. I have seen 400++HP SR20 and CA18s with stock internals living a long life, being thrashed on tracks. I also have seen rebuild block with forged pistons and rods die from knock and too high EGTs caused by using a wrong tune...

Loose or used bearings, or anything that is not a custom tune on a dyno, with some big turbo like that one and counterfeit wastegate though ... i would not bet on its life expectancy.

I agree with

Hey guys, the SR marking I agree with...it's the 2JZ limit that I do not.

Turbonicsperformance · 01-19-2013, 09:59 PM

very much so. There is a 100% never opened 2jzgte in tampa making 800 whp daily driven. seen tons of 600 hp+ stock 2js also my buddy dane make 630 whp in his s14 2j swapped stock internals studded head

STR8E180 · 01-19-2013, 10:03 PM

from a sr20 with a standard bottom end the most we have made is 400kw/540hp this was done with E85

at 35psi the standard head bolts will start to stretch causing the cylinder head to lift of the block resulting in a split head gasket

i wouldnt recommend trying to make this sort of power level on 91 octane fuel ( or what ever you guys got over there ) its only safe on E85

Agreeing or disagreeing with me?

I guess my point is that I'd move the 'good' line further to the right in regard to safe power level of the 2jZ
