Thread: sr20det bluebird vs sr20det gtir

Um... I have no problem testing the limits of stock internals...LOL. Alex you have been to the shop and seen the motor selection. De+t, DET, GTI-R they are all good for 400whp on stock internals..... I do recomend that whatever motor you choose that you replace the rod bearings right from the start.... Rod bearings are the weak link in the Sr motor... As been mentioned before, for your build needs goto Gspec performance.. Greg is an awsome guy and very helpfull... Also start thinking about what you are going to use for engine management.. without that you just have a shiney motor in a car that will not run.

A shiny engine that does have a turbo attached though, LOL Tuning is very important as Eric said. I also agree on the rod bearings if you are swapping the engine. If not, I would just bolt on, tune and go until the bearings that are in there start to go. It is very rare to actually spin a bearing, usually the crank is ok. Once you hear the #3 rod bearing start knocking, you can still replace the bearings and be ok, most of the time.

yeah do it twice so its extra nice, take the time to do the bearings it will save you money and a lot of headaches in the long run.

if you do decide to do the gti-r motor I have one for 900 cash

whats up lance. its good to see your still around and posting !

ill ask you cause i know your an og and have built enough sr20's to know whats what.

stock de motor what the max safe whp would you recommend going up to ??

reason i ask is cause im at 303 whp @ 15psi on a t28 (this was on a dynodynamics dyno) and im looking to upgrade my turbo but not my motor lol. would like to make the max safe whp i can. im thinking a gt2871r would be perfect at a safe boost level.

t.i.a.

stratton.

I know that you didn't ask me personally, but I would safe limit on internals depends on a few different things. With out going into details I would also say that a gt2871r would be perfect for what you seem to want. Stock internals should be fine.
