I have got 200,000 miles on my prelude I want boost but not sure where to start I have got 3200 to spend. What's the best comp ratio for boost?

 

I would recommend lots of research before you undertake your project,
there is a lot to consider, a good starting place is the FAQ, it has lots
of good info on this topic. Here is a link to the FAQ and another thread
you may find helpful re: heavily modifying a prelude.

9.1 comp
h22 cyclinder walls cant handle much boost
get new pistons & rings all internal bearings. arp head rod bolts
oil n water pump. im rebuilding mine too, jus took it to the shop today

3200 is really high for rebuild. i would get sleeves with it too

 

With 3200 you will not get too far...

 

3200 will get you far DUD
you jus have to kno how to shop

 

If you're actually doing the build as you claim to be, you'll soon learn that 3200$ disappears when you're chasing performance. How much do you really have left after forged pistons, rods, bearings, cylinder sleeves? Enough for your EMS system, your tune? hell you haven't even started on the "boost" aspect of the build yet.. lol

 

Your obviously repeating "what you heard" from your best friends brothers friends mothers uncle and do not know h22 very well. They do not have weak stock cylinders.

 

I would worry about the rebuild part first and keep things in mind for turbo later; $3200 will go faster than you think. At 200,000 miles, if you want the car to last a while, you've got to consider more than just the engine. Chances are the tranny is due for a rebuild plus some wearing suspension components to name a couple. I don't know how long it's been since you replaced the clutch, but if you're going boost you will need something beefier than stock anyway to handle the torque. Redo all the seals and bearings, put in rods and low comp pistons and get some engine management and a tune and that $3200 is gone. However, you are now in the right place for when you get your next chunk of cash and you can throw the turbo kit on and re-tune.

 

i agree, 3200 is not enough especially if your going for boost. i just finished a n/a rebuild and i was just around that amount. when you start taking things apart, you start to notice things that need to be replaced, especially at 200k. some things can be cleaned, some need to be replaced. this was the first time i ever broke an entire engine down and there is alot of sh*t involved. you also need to take into consideration upgrading some components in the cylinder head. it is most definitley a huge job to undertake and i have found since i started working on cars a good rule of thumb: whatever your budget is, its probably going to cost more, and whenever your "projected" finish date is, add a couple of months.
good luck.

 

Just slap in a set of Mahle 9:1 CR pistons, ACL race bearings, ARP Head Bolts, and rods(ARP rod bolts) and you'd should be set to go.

Cause the ringlands are hella weak on the H22s when it comes to boosting.
