So I picked up a d16a6 with around 120k miles on it about a month ago (for a 1990 crx)


Since then, I've compiled a td04h turbo and a t3 turbo, (which one? im aiming for ~250whp) intercooler and piping, an hf exhaust manifold and that's about it turbo-wise... where can i get a downpipe that fits the turbo? do i have to get my car towed to shop for them to weld one tegether? (im broke...)

i was planning on leaving the head untouched, and getting some tuner toy rods and vitara pistons... along with arp head studs and rod bolts...

ive read online that i should also get some acl rod and main bearings so i wont spin a bearing... is that necessary?

Can i take my block to a machine shop (fully assembled) and have them dissassemble, hot tank, and install the rods/pistons/bearings?? or can i do it at home? and what tools do i need?



also, car is going to be tuned on turboedit using a pm6 (I already chipped it myself )... i have all the necessary parts for that, but i might post questions about the tuning process...

 

Noob go post in the tech section you cracker lol come back to nova homie

 

First do a compression and leakdown test if everything is good then I would turbo the stock motor. Since you are trying to go with one of the HMT setups yes you will need to have a muffler shop weld you up a downpipe. The a6 should be able to handle putting out 250whp stock with a very good tune. The turbo we cant really tell you, we need more info on them.

 

i was under the impression that the a6 couldn't handle more than 160hp on stock internals...

when i rebuilt my old d15 the rods where the size of my pinky!



could i buy a premade downpipe from like inlinepro or something?


and does anyone know what the t3 is capable of? the td04h? (I think it's a wrx turbo?)

 

You will have to provide the size of the turbo's to give an idea of what they are capable of. that info you can find stamped on the housing or on a plate

You will need a fabricator to weld a DP for you. I am not aware of any vendors selling one premade for the HF mani. You can try to find a used one if somone is selling their homemadeturbo setup.

With the age of the motor, i wouldn't push more than 7psi on stock internals. I am selling Eagle Rods and Vitara pistons.

 

id like that very much! although, i would rather measure the bore of my a6 to double check if its 75.5


do you think it's necessary?

 

several people have used the 75mm vitara and aftermarket rods (Eagle or Tuner Toys) to break 400WHP. it is a proven recipe. it will be more noisy on startup.

75.5mm is preferable if you need a cylinder bore/hone and need to go bigger
