SR20DET rebuild

[GTR Dreamer]

are the stock suspension/brakes ok?

HKS, GReddy, turbotenics. i've looked around and seen a garrett T3/T4 turbo can handle 16-20 PSI tho am not so sure, you do have to upgrade the fuel pump and injectors, as the stock wouldn't handle so much PSI, seen sr20's with 550cc or 740cc make 400hp, and a 255lph(however ya spell) walbro fuel pump.

for safety reasons yes, an upgrade to the suspension and brakes would help, it'll make ya stop faster than the stock brakes, and some suspensions even help with the traction.

thanks.
i was just looking at a local NZ magazine and one of the colums is called 'speed clinic' this is where readers write in asking technical auto questions. any way one guy asked about fuel pressure regulators, the reply was quite interesting. sounds as though u wouldnt need to go to bigger injectors for more response, just turn it up 10psi or so and ur away. what do you think about this on a SR20DET?

yay!!! not confused any more.
so if it diddnt have a rocker arm, would the lobes just push the valve?

The camshaft lobe hits the bottom of one side rocker arm which in turn makes the other side of the rocker push down and open the valve.

i have now found out how much some pistons will cost, these are off the shelf with a bore of 3.386 but custom ones cost even more, do you think the off the shelf pistons would be ok? they cost $3200NZD

also i have found out how much 4 crower conrods is, but there are 2 ways i can go
a. steel billet rods, @ $1060NZD for 4
b. titainum rods, @ $2200NZD for 4

what do you think will be best steel or titainium?

or i can get a GReddy stroker kit for about $5000NZD i dont think this will be as good as crower or JE though, am i right?

I looked at the conversion rates (NZD to CAD), and still, it seems that those prices are pretty ridiculous. Are you really considering paying a large part of what the car is worth for a few small parts? From what I've heard, the SR20DET is a fairly strong engine...

I think the best option would be the most cost-effective route... find a local tuning shop, and ask them about the most reliable and cost-effective way to get more power. Especially try to stay away from GReddy parts, though. They may be decent, but you can easily find equivalent parts for waaaayyy less money. GReddy marks up their prices just because they've become an established name brand.

If your looking for some serious help with the SR20DET let me know, I have a Datsun 510 with a T3/4 Turbonetics Turbo with MSD Injectors (Yes Top Mounted) pushing 20psi @ 503 WHP. I did all the work myself (except machine work) and you can easily get 500 HP for 3,000.00 USD. I wouldnt recomend much past 600HP unless you have your block modifed. If you want more than that go with a RB26DETT.

Email me with any questions you might have.
