Hey just got my prelude and have few questions on replacing the engine. Hearing mixed answers on the question of the H22a4 BASE engine on the Type SH transmission, just want to clarify. Also, anyone in the MD/VA/PA/WV area have an h22a4 for sale....i can use one

it shouldn't work. you have to use the atts unit with it and have to use the sh block in order for it to hold the atts unit.

yup, SH block and SH trans together .. you can not run one without the other. I'de go with the Base instead of the SH model as a personal preference, more room for power upgrades.

Hmm the guy i got the car from told me somethign about using a base engine and removing the atts unit, getting a new axle or some **** like that. I'm trying hard to find an SH engine for under $1000 :/ hard to do, cant spend more on base + tranny either :/

Pearlwhitesh

you can run a base tranny on an SH motor buy making a plate to bolt to the back of the block and using an halfshaft but you can't use and sh tranny on a base block.

Thanks for the answers, got an SH longblock off ebay, from a parts dealer (42000 rated, engine compression tested and leakdown tested), bought a whole bunch of gaskets for intake/exhaust manifolds, rear main seal, etc that i didnt already have, thinking about doing the whole manual tensioner thing too, what are the benefits of this?

Its less prone to failure, more peace of mind. On a stock engine driven stock-like its not that great of a worry. But I would recommend it, its definitely a better safe than sorry type of situation. A couple hundred bucks on the conversion versus a jacked up timing belt...you can do the math on that one.

I would also look into balance shaft removal.

Heh, accually the guy who owned the car before me put the manual tensioner on the engine, though that engine is bad now, and going to be replaced, can i use all of the parts from the old one to do the manual tensioner?? or are some/all new parts recommended

I found a sh engine for 900$
Okay one question, will an sh engine work with my base transmission? Been seeing a lot of mixed answers. Thanks

The engine will work fine, but you will need to fabricate something to support the intermediate shaft for the drivers side axle.

With Kaizenspeed h22 tensioner you only need one part - not like h23 manual tensioner swap and kaizen is reusable

So basicly thats "not directly" :D

I have a base model engine with no issues trading for sh
