1: Nis­san Gar­rett T28 and GT25 se­ries

NZ Performance Car - - Scrapyard Gains -

Through­out the ’90s Nis­san re­leased sev­eral pow­er­houses that shook the au­to­mo­tive tree, and caused many up­sets thanks to tur­bocharged tech­nol­ogy that re­mains very im­pres­sive to this day.

There are three dif­fer­ent types you should keep an eye on. The Gar­rett T28 ‘frame size’ turbo was one of the largest to come from Nis­san. The Gar­rett TB2804 turbo as fit­ted to the Pul­sar GTI-R was re­leased with the largest ex­haust hous­ing of them all. We have seen plenty of ap­pli­ca­tions for this unit with boost as high as 18–20psi. It’s a fan­tas­tic up­grade for east-west–con­fig­ured en­gines such as the Avenir GT4-Z or U13 Blue­bird, or as a bolt-on plus-T op­tion for SR20DE/VE Primeras and the like. Ex­pect to see 200–220kW out of this turbo, depend­ing on your tune and sup­port­ing mod­i­fi­ca­tions.

The Nis­san Sil­via S15 Spec R was re­leased with the best OEM turbo avail­able — the GT2560R. It fea­tures ball bear­ings and a large tur­bine wheel and com­pres­sor wheel, sim­i­lar to that of the GTI-R turbo. This is a fan­tas­tic bolton up­grade for your CA18DET or SR20DET Sil­via, and will punch out a very re­spon­sive 220kW with an up­graded ex­haust sys­tem, in­take, in­ter­cooler, fuel pump, and Z32 AFM. This turbo is a great up­grade for many ap­pli­ca­tions, though if you wish to retro­fit it to an­other en­gine, a four-bolt T2 flange is needed, along with a five-bolt flange to marry it up to your new down­pipe. Both of th­ese tur­bos are wa­ter and oil cooled.

Own a Nis­san Sil­via? The GT2560R will han­dle a safe and steady 20psi of boost in the right ap­pli­ca­tion, and will sup­port over 200kW with ease, pro­vid­ing you have the right bolt-on mod­i­fi­ca­tions
