First off this is for my buddy's car a 1990 1.6 car that has the 1.8 rear end and axles in it. I am currently building the car for him. He is looking to spend 3-4 grand on just the kit and then also buy the MS PNP. He wants a good clean 12 psi. I will be porting the head and adding a set of cams. Thank you for the help.

No body has ever turboed a 1.6. I am sure you searched and the search doesnt work.

12psi on what? 2586? TD04? EFR? Shop-Vac?

we only know how to boost a dirty 12psi.

clean 12psi is tricky.

I run my tires no lower than 22psi.

I usually fart 12psi but had to turn it down cause my rod was bending

I wanted to fart at 12psi but I felt my waste gate opening.

you should port your wastegate

by clean I mean cool and I was thinking a ball baring gt2560r may work. I'm having a hard time with this small stuff its way more lag sensitive as my 5.8L based motor.

Is the 2560 to small or is it about right on th head cams 1.6

The 2560 is a good size for the 1.6 engine. You'll be happy with it. You can approximately double the stock horsepower without issue and without opening up the engine.

How hard can I push it could I push it to 300 rwh that's the customers goals ? He is willing to replace the pistons and rods if necessary. Is the GT2860RS a better choice?

If this guy is a paying customer and you've having to ask these questions, i would suggest saving face and hassle in the end and pointing your customer towards someone who knows what they're doing. You'll end up ahead in the long run.

like I said I primarily work on motors that are at least 5 L they are much less sensitive to turbo size. I know how to do all the work how to build the engine and I have turboed many engines just not as small as the miata motor. I am a smart enough man to know that I do not know every thing and to ask for help when I'm not absolutely sure. If it was a going on a stock motor I wouldn't be asking for help as I would just use a previously proven set up.

This is a stock motor, though. Or at least judging by what you said in the first post.

If he wants 300whp reliably, he'll need a built bottom end, which comes with a whole 'nother set of decisions to make.

The 2560 won't make 300whp. 2860 is the bare minimum and you might want to look into fancier options.

If you're building a motor anyways, using a 1.6 is full retard status, though.

This x 1000. Especially if the customer wants to be in the neighborhood of 300 HP.

I say this and I have a boosted 1.6.

The only good thing about it is that I can run ALLOFIT without any real ***** given. If the motor pops, it's all the more reason to swap in a 1.8.

"I want the laggiest and shittiest 300hp available to me in this chassis, please. What can you do for me?"

c4boom

That's what I told him I wanted to swap in a 2.0 but he wants to keep the 1.6. How much horsepower is the stock crank good for? I'm going to Wiseco forged turbo pistons Manley H-beam rods compression should be around 8.5:1
