h22a4 turbo

i have a 2001 honda prelude base
my plan is to buy a block and build it on the side as i get the money
i would like to run a turbo so here is my question i dont want to have to buy a new exhaust when i finally make the swap so my current motor is in excelent conditon but has 98500 do you think that i would be ok to bolt on my turbo setup to the stock motor and run 4 psi till i do make the swap, ive heard the stock motor can handle 6 to 8 psi but i dont want to push it to its limits but i dont want to replace a header and down pipe in a year either thx

both of you will be fine doing it. the mileage really doesn't matter that much. just do a compression/leakdown test to make sure everything is okay with that. i'm running 7psi on my daily driver and haven't had one problem with the greddy kit. it's also not so much the psi as it is the actual power you'll be making. the 18g is a great turbo with great spool. but running it at 7psi on it as opposed to running a gt35r or sc61 is a big difference in power. also make sure you have good injectors and also a good tune.

it will run fine its just that you have a greater chance to spin a bearing on a motor with vtec but 4 pounds woudl be fine just dont push it to its limits alot id get a hatch and swap that motor in it and sell the prelude sheel thats just my personal opinion but you may be a prelude lover

What the hell are you talking about? Spinning a bearing has nothing to do with having vtec or not, it has to to do with clearances between the bearing and the surface it's protecting.... I.E a rod bearing for instance, run it to tight, starve the bearing for oil and you'll see what a spun rod bearing looks like. :noo

What he said......tuning and actual power being made are what determins the longevity of your motor...

7psi is just fine. thats what i'm running and haven't had any problems at all. the greddy kit is a reliable kit. kind of wish i would have pieced together the kit though. once my engine is built, i'll definately upgrade the turbo.

sorry if i this is a stupid question but i have read so many dif reasons for what causes theese motors to blow but as long as you dont run forged pistons my understanding is that the stock sleeves will hold together pretty well and i dont believe that the type s pistons are forged correct me if i am wrong newhere in this post, so type s pistons, aftermarket rings, block guard, head gasket, and some arp head bolts couldnt this motor run safely just guessing say 10-12 psi daily? or more than 7 neway!

If your using strictly the greddy kit then Yeah I wouldn't run more then they recomend (7-8psi I believe)..Tune with hondata and larger injectors and you can probably run more.

I heard of a lot of people having cracked ring lands. The problem is that on those motors the top ring land is thin so any little bit of detonation will crack them...The stock sleeves are fine, look into mahle pistons (search other honda sites there is one in perticular that has a post pertaining to these pistons in the h22)...you can run those w/stock sleeves...With those pistons your should be good for 400whp +...it's not the amount of boost that determins the limits of your engine, it's the quality of your tuning and the amount of power being made....15psi doesn't blow a motor, but poor tuning does. Same goes for boost pressure, you can run 10psi(large turbo) and make 300whp and be fine, or you can run 15psi(smaller turbo) and make 300whp and still be fine...larger turbo's make more peak power while smaller ones make less.....

ok well thx for shedding some light on the subject, my brother is a porgrammer and has spent the last 2 years building his 98 gst. body and interior are about all that is left stock, with his current set up he can easily hit 30psi, but he only runs 22 low and 26 hi boost and we estimate in the area of 400-500whp, so with his knowledge of turbos and tuning abilities is it safe to say that with his help i should be able to build my motor without sleeving it? only lokking to run an absolute max of 15 psi i would like to put about 300whp and not looking really to run any faster than 13's
