Here’s the beast. Only put 115 miles put on her so far. This car doesn’t feel as fast as my civic but in reality is much faster just heavier with better suspension. Need to find a place to whip it through corners and have some RWD fun.

For sure! I’ll post it in this thread for sure. If only I could reliably coyote swap into this car lol.

The Si built block is plug and play pretty much. I was going to go through my mechanic to build my motor but after thinking about how much more money I was going to have to put into my car just to make more power I decided to sell my car and buy a mustang bullitt. But after all the research I...

Okay well everything is purchased now. Tsp built block, intake, exhaust cams for the Si, 4 bar map sensors, titanium valve springs and retainers, timing tensioner, and cam chain covers. I’ll post pictures of everything when I’m off work except the built block because it’s still being assembled.

Okay recently I’ve noticed a sound when accelerating and decelerating that sounds like a siren. Might be coming from turbo but I’m not sure if it’s coming from the engine bay or the exhaust. It’s most noticeable when decelerating in 2nd and 3rd gear. Could this be normal operation sounds or...

Yeah that was the only way I could get them other than scouring junkyards.

I was able to find the intake cams on a Honda parts website but had to jump through a lot of hoops to get it.

The cams came in today finally, both are looking good and now I can focus on valve springs, a new OEM head gasket, and some 4 bar map sensors.

Also, does that mean that the journal bearing W2 is good for intermittent pulls and light racing? Or is it just as good but won’t hold up as long as the ball bearing version?

I read that one of the pumps is in a different location lower than on the L15BA

Gotcha, I’ll use the factory gasket and I haven’t purchased the arp head studs yet either. Trying to stagger my purchases so I don’t empty my bank account. Belt came in today, hopefully Honda will get back to me with the cams. Then I can get the oil gears, retainers and springs, and anything...

Will the factory one hold up to 30 ish pounds of boost?

Belts are on the way, Honda is being stingy with the cams saying they’re “controlled product”. Used a vin from a salvaged civic Si to confirm the si engine I’m getting.

If they have it’s kind of garbage. All I did was take a VIN from a salvaged civic Si. I’ll update if it works and they get back to me.

Thats what its looking like im going to have to do. Why does honda make things so difficult. They told me its a "Controlled Product". I'm looking at salvaged 2017 Civic Si's

Hey guys, Trying to get some Si intake and exhaust cams for my civic hatchback but honda requires a 2017 Civic Si vin number to complete the purchase. Can anybody help me out?

I'm good on that front, the TSP block has saenz rods and JE pistons.

Hi, I'm building my motor to make more power and hold the power I'm currently making. So far, I've made 330 whp and 318 wtq on e30 and I feel the itch for making more power. I've recently purchased Si intake cams, exhaust cams, a cometic L15B7 headgasket, L15B7 ARP headstuds, and a belt to work...

Thank you! I’ll be making one for sure, I’m buying the tsp short block but I’ll keep you guys updated!

Lmk how the retrofit goes!
