So to make a long story short I was planning on boosting my d16y7 this summer to make 300hp cause it was a goal for a bit. I told some friends at work and my buddy with a Miata says he's gonna boost his as well for 300hp. Considering how light a Miata is and the power he's planning to push, I want to step up my game since I refuse to lose to a Miata. So my new goal is 400hp and making it a daily driver. I feel that with the parts I plan on using that this should be more than possible and If there's anything I should change please let me know.
Parts Lists consist of
-D16Y7 HEAD
-D16Y7 BLOCK
-D16Y7 CRANK
-D16Y7 Cam
-Ferrea 6000 series STD Valves or 5000 series i don't know the difference
-Honda OEM head gasket
-Wiseco pistons
-Eagle Rods
-Skunk2 Pro-Series Cam
-SuperTech Valve springs and retainers
-ARP head studs
-CXRacing Turbo Kit or Rev9Power Turbo Kit
-Kings Racing Bearings with extra oil clearances
-Kings Racing high-performance thrust washer set

With these parts could I achieve 400hp or maybe more safely? I didn't list the injectors or fuel pumps because I don't exactly know which ones to get at the moment. I've seen a few d16s on youtube making 400-600 hp on similar setups in terms of pistons and rods and stock sleeves and I'm trying to go for the same goal just reliable. Feel free to recommend any other parts for this.

"dumping money"

picks eBay turbo, y7 engine, no tuning software, no transmission or suspension upgrades.....

88-00 Civic/90-01 Integra

GO-AUTOWORKS RR A/C Turbo Kit 250-600hp Civic Integra D16 B16 B18 B20
ok then, it's gonna run a Hondata s300 ECU, stock trans with an act clutch. What's wrong with it being a y7 motor? I didn't list this stuff before since I was purely talking about the motor internals. I know the z6 would be a popular choice because it has a better oil pump and such but what's wrong with a y7 besides it being non vtec?

Let me help you walk through this.

He said that because the Y7 is one of the least efficient engines of all the D's. And it is prone to oil starvation and blowing up. So if you are really interested in whooping the Miata boy, here's the recipe to 400 reliable whp.

Start with a D16z6 block and crankshaft. Send the block to CSS and have Jeff do that process to it. You'll have $400 in it but it will be guaranteed to 600whp. Second thing, have Jeff install 11mm timeserts in the block, so you won't have to worry about head lift. Now I'm going to walk through a list of parts that are proven and will last on a daily driver even:

Injector Nation 1000cc injectors
Z6 intake, stock throttle body
Crower 2 cam or Rocket Motorsports Stg 4 camshaft also with the appropriate springs for the camshaft
Head will need to be worked over and not by a novice, by someone that knows D16 heads: our shop does this
Wiseco's. 9.5:1, great choice
A good H beam or I beam rod that has ARP bolts in it.
A log manifold will suffice for this power level, but you will need to match the turbo fairly accurately. No CX or Rev9.
G25-550 or GT2867r Gen 2 to make the numbers you want. The G25 is what I would choose. You can get it internally gated to make life easier on you and it will be reliable. You will need a decent BOV as well. So no EBAY here either.


With that set up, and if you can drive at all, you will leave him immediately and he will never catch you. The turbo will spool at 2k and it will be full boost by 3200 and take that to redline.

Lastly the tune will be key. Someone could easily screw it up, so that will need to be spot on or it won't last. Where are you located?

ran my last y7 vitara build into the ground with an hy35 at 28-30psi on water/meth ,
virtual dyno was reading between 420-440whp depending on weather.
lasted longer than expected ...but not long enough to be considered daily safe..
