Gt2860r/gt2860rs And Sr20dets .

[discopotato03]

Mortal unfortunately but IMO GT2860RS every time .

These are difficult to beat for the power outup they were designed for which is probably around 320 + Hp .

If you don't have control of your engines fueling and timing then yeah go for the GT2860R .

Don't want to go too deep but wheel wise a GT2860RS is GT"2530" but with a slightly smaller trim compressor (62 vs 63) but greater exducer tip height .

They also use (were intended to use) the larger of the two turbine housing sizes (0.86 A/R vs 0.64 A/R) .

SR20 people who don't have the means to tune or can't/won't accept that more advanced timing where necessary really wakes up an engine with the larger housing use the smaller housing - which chokes the engine .

The feller that spec'd this turbo (JC) used to work for Garrett in the US and wanted something for his circuit Miata (MX5) and the GT2860RS 0.86 A/R is the production version of what he put together . He needed a turbo for his BP18 that would be responsive without being restrictive on the exhaust side and that is what he got .

I had possibly the first one sold in Aust and used it on a street FJ20ET which worked really well .

These are not a numbers turbo for bragging rights but they make an excellent torque in the sort of rev range most 2L engines are driven in .

There was an article in the June 2003 Sport Compact Car - Project Nissan Silvia Part II Behold the Potato .

I'm sure if you search you'll find that one and it has most of the turbos details and pics , and how it was fitted to a JDM SR20DET in a USDM S13 .

Hope this helps , cheers A .
