will the s15 turbo bolt on the the s13 redtop because the stock turbo in my car is starting to burn oil. im lookin to fins another stock turbo but i wanna see if a s15 turbo would fit on with no adjustments.

 

I know it bolt on to the stock manifold, but can't remember if there are small modifictions needed to work properly

 

its funny.. i got the latest issue of import tuner.. and they did the same thing.. stick the s15 turbo on it and it bolted right on. they gain and lost some hp becuase the stock MAF wouldnt work that good with the turbo. they said youd need to change it.

 

The s15 t28bb will bolt on to the s13 manifold. The s13 coolant and oil lines may need a little bending to get it to fit or you could use the s15's, or get steel braided. You will have to buy one of those adapters to clock the turbo so the hotpipe will bolt up or just make your own. The s13 maf will run out of flow as will your injectors so upgrade those with a z32 maf and 550's while your at it. Enjoy you new hp!!
