sr20 max turbo size without internal mods???

[deathBooster]

Hi guys.. right now i have an redtop sr with a T28 turbo not sure exactly what model but it is good up to 320HP with correct mods.. using 555cc injectors, z32maf. 3" downpipe all the way to muffler.. did not mod engine internals... and boosting 13psi max... I boost all the time and my car is safe no over heat etc... btw, i got a greddy FMIC and aluminum koyo as well..did not have the chance to dyno.. there is no cheap dyno inthis area..

now my question is... WHAT IS THE LARGEST TURBO I CAN USE safely in a redtop sr20 without internal mods??? can it be possible to get it to 400HP+ just by adding a turbo and injectors????turbo model please... and neccessary mods....

Oh look, I found this in the SR FAQ sticky: zerothread?id=59344

[deathBooster]

Thanks mic... I see what is the problem with searches.. The answer is always there it is just hard to figure out what is the combination of words to put in the title... lol...

I guess i should take my car to do serious dyno tune.. before pulling more money out...

also maybe rocker arm stoppers if you don't already have then. my 2 cents.

[deathBooster]

I never thought of that.. i found couple.. they are not expensive.. but.. where do they go?? is it hard to instal?

[FattyMcBaggins]

well, they're called rocker arm stoppers...so...well...they kinda go on the...rocker arms...so they can...um...stop them from flying off

Its quite easy. They go under the valve cover and attach to your camshaft brackets. They have fingers that hover over the rockers to push them back down if they happen to pop off. On s13's there is a plate on the exhaust side that you have to grind a tad bit to make them fit easily. They will probably fit without grinding the plate but the bolts may bind a little when trying to put them in their holes.

No they don't go on the rockers. They sit above them. Why do you have to be so condescending? It was a simple question that you obviously didn't know the answer to. So ummm well ummm so ummm ummm well (<--- look familiar?)...

gt2871r. its the answer to everything.

[DRIFTINIZ]

to upgrade to this turbo, what needs to be modded in order for it to fit, or is it direct bolt-on??

[DRIFTINIZ]

gt2871r. its the answer to everything.

the gt2871r that is......

[spider_slayer]

the period was intended. it makes the statement more concise and to the point.

yes owned.. lol

[D1 guy]

Yeah the gt2871r is the only way to go as far as Im concerned. I was almost talked into the .64 ar......but I decided to go with the .86 and Im proud I did. The lag isnt bad at all and its well worth a little lag.

[BurnsAuto90]

it all depends on the tuning man, you cant just have someone tell you a turbo and expect them to be right, especially not on an online forum. its all about the tuning, tuning, tuning. I've seen 475 whp on the stock sr bottom end. Since you dont have the cash for a few dyno tuning sessions, I wouldnt go too big, or...save up the money and at least have the head reworked (cams, valve springs, rocker arm stoppers, maybe a port job).

Whatever you choose to do, do it right. A bigger turbo isnt always the best idea and can sometimes scatter an engine..

a bigger turbo is always the right answer when modding the engine. sure it takes a new fuel system and a standalone and countless other things but the newb will figure that out for him self upon some research.

the stock turbo is worthless. thats why you can buy them on ebay for >$200

and if you are running the stock turbo head work will do NOTHING. upgrading to more aggressive cams will actually hurt a stock engine more then help it. also there has been more then one post explaining how even on high hp engines P&P is money wasted.

Well, you won't see 400 whp w/ a gt2871r unless you replace cams and get an intake manifold (I'd reccomend the intake manifold either way). You'll have to run something bigger. Also, if you ever plan on going past 400, a t2 flanged gt2871r is not the way to go. Personally, for your power goals, I'd build your head first because you should be taking your head off anyway (since a head gasket upgrade at those power levels is pretty much a requirement). If you ever think you'll want more than 400, get a top mount manifold and consider any of the numerous turbos that will fit it and take you past 400.

[spider_slayer]

granted. but my point was that without a larger turbo in the first place head work is more or less a waste of money. now if you PLAN on upgrading and actually do...then it is of much benifit.

I didn't reply to you.
