tacker Posted February 19, 2007 Share Posted February 19, 2007 Anyone care to comment as i have to build a new engine. I have some N1's which will need a rebuild or some new garret 2860 -5 Link to comment https://www.sau.com.au/forums/topic/157016-nismo-n1-vs-garret-2860/ Share on other sites More sharing options...
sav man Posted February 19, 2007 Share Posted February 19, 2007 N1's are laggy as, we have them on our Targa car. My car has HKS GT2530's (same as 2860 -5 i think), and i'm on 1.1 bar @ 4400rpm, the N1's are on 1.1 bar at over 5000rpm. I'd go the Garrett's if you can afford it.

Mr. Keets Posted February 19, 2007 Share Posted February 19, 2007 Depends on how much HP you want to run and what sort of response you want. I've got the 2860-5 and they come on at around 4K and make 430RWHP without cams. You sacrifice a little response but I think they're worth it. PNBlight makes about 520RWHP on his 33R, but I would'nt expect to get alot more. From memory Garrett advertise them as a "replacement upgrade "for the 34 GT-R turbos (-7). N1 and 2860R-5 really are quite different turbos and therefore not really comparable. You'd be better off comparing HKS2530, 2860R-5 and Trust T517. There was a good thread that contained a side by side comparison just recently... the HKS 2530 and the Trust T517 have more legs and produce more HP at higher rpm respectively. That would make the 2860r-5 a good comprimise for price and reposnse.

tacker Posted February 19, 2007 Author Share Posted February 19, 2007 I dont want to run more than 1.2 bar as its on stock internals ( last engine died on .85 bar bloody stock turbos ) and big horse power is not the objective just want a good solid performance.

If you are talking R32 N1s (aka Group A's) they are laggier still but have pretty decent power potential.

tacker Posted February 19, 2007 Author Share Posted February 19, 2007 As i dont want to run a big top end the smaller N1 would be more suitable. they are from a R34 and have a A/R of .48 Still the cost of rebuilding N1 turbos is almost the same a new Garrets Link to comment https://www.sau.com.au/forums/topic/157016-nismo-n1-vs-garret-2860/#findComment-2916448 Share on other sites More sharing options...

tacker Posted February 19, 2007 Author Share Posted February 19, 2007 Yer not that easy over here, i guess i could find some one to rebuild them but no part available so would have to order them and wait. Think the new garrets maybe the more effective solution in this case Cheers all Link to comment https://www.sau.com.au/forums/topic/157016-nismo-n1-vs-garret-2860/#findComment-2916566 Share on other sites More sharing options...
