My '00 ZX3 race car has gone through many forced induction phases over the past couple years. It started with a 177whp JRSC, then last winter I swapped to a PWSC and made 203whp, but this winter I'm doing what I should've done from the very beginning, TURBO! So, this thread will detail my turbo build that will be built/tuned specifically for road racing and hopefully net me at least 325-350Whp in the end.
BUILT BLOCK
Back in late October of '09 I found a great deal on a built Zetec short block via Craigslist. The block was fully built with 8:1 pistons (I think JE brand), Oliver rods and a balanced rotating assembly.
The block had everything I need EXCEPT for ARP main studs. The Oliver rods already have 3/8" ARP 2000 rod bolts so I'm good there. So, I recently picked up a set of ARP main studs and splurged on ARP head studs as well.
Due to the extra clamping force of the ARP main studs (and just to be safe), I'm going to have the main bores line honed with the ARP main studs installed to make sure everything is true. Since the block is going to the machine shop, disassembly was necessary, but this gave me the opportunity to take a closer look at the pistons, rods, crank and bearings used in building the built block. So, what do you think of these pistons, JE brand??
The block is going off to the machine shop in a few weeks, so in the meantime I'm disassembling the previous engine and also doing some mock-up of the manifold, header, etc.
Now, on to the good stuff! Below are the parts being used in the turbo build.
TopSpeed RACE manifold
Turbo
Garrett GT2871R (w/4" anti-surge compressor housing)0.50 A/R anti-surge 4" outlet
The compressor side is currently a 0.50 A/R anti-surge w/4" outlet. The turbine side currently has the 0.64 A/R T25, 5-bolt discharge w/internal wastegate , but I'm going to swap that out for a 0.63 A/R T25 Plus, T25 Inlet Flanged, T31-V Band Outlet Turbine Housing (http://www.atpturbo.com/mm5/merchant.mvc?Screen=PROD&Product_Code=ATP-HSG-042&Category_Code=GTH)
Here's the manifold and turbo mocked up on the old engine:
Intake Manifold
The intake and TB being used are the FRPP intake with the FRPP 70mm throttle body.
Intercooler
400HP Garrett High Density Intercooler Core w/ATP Cast End Tanks and 2.5" inlet/outlet hose connections
Wastegate
Tial MVS 38mm v-band (which will dump to the ground)
Blow-Off Valve
Currently I have a Greddy type-S knock-off, but this will probably be replaced with something different.
Other stuff I've acquired
So far I've also picked up:
- FelPro upper gasket set with stock thickness Zetec head gasket
- FelPro lower end gasket set
- Motorcraft EV111 PCV valve for boosted applications
- Motorcraft replacement timing belt tensioner
Still need to purchase
- Billet timing belt pulley from Gold Coast
- Alternator bracket spacer for FRPP intake from Gold Coast
- Gates blue timing belt from somewhere
Thanks for reading. Comments welcome.
