Hello,
I posted a month or so ago about turboing my F22, but came into some money recently and decided to go the H22 route instead. I'm buying a JDM H22a front clip at the end of December, swaping it into my 95' Accord EX, and then want to turbo it. I'm going to build my own kit with a buddy of mine (who's already turboed / tuned his focus) and then after its on, def get it tuned. I know that the H22 does not like boost very much when it's in it's stock form. I know that the stock sleeves and the ringlands don't hold up very well to boost. Basically, the questions I have are these ...

1. What's a safe amount of boost to run on a stock h22? I'm thinking 6psi w/ a good tune ... until I get the block resleeved and build the bottom end
2. Where do people usually shift (that's the max, but still safe)? I've heard about people shifting at 8000rpm, 8500rpm, and even 9000rpm ...

Any help / advice / info that you have is greatly appreciated ... thank you

Usually people run 6-8PSI tuned. Ive heard people run a little higher but thats pushing it. As for shifting RPM i wouldnt go past 7400 to be safe unless you have an upgraded valvetrain.

 

I've been looking at different turbo manifolds for the h22a and I was just wondering which was better ...
TM #1



TM #2



TM #1 sells for roughly $750 and TM #2 sells for roughly $200. If $$$$ was not an issue, which one would you get and why? I'm not sure if TM #2 has equal length runners, but I know that TM #1 does.

 

#1 is a reputable brand which you will not have problems with
#2 appears to be "SSAC" brand, which many many people have reported cracking and other major problems with (ie: wastegate FALLS OFF while driving down the street)

#1 is equal length, #2 is definitely not, but that's not really a huge deal.

but think about it, why on earth is one 3x the cost of the other? you get what you pay for. search for SSAC in the FI forums here for more information.

 

I don't feel like making a new thread b/c I think it would be pointless ... so I'll just post about it here. hopefully someone will read it ... anyways ...

what's the best route for swapping an h22 into a 95 honda accord? i can buy a complete 94 jdm prelude front clip (w/ original tranny + an lsd tranny) for roughly $3k shipped. is there another way i can get all the parts i need to do the swap for a cheaper price than $3k w/ lsd tranny? i'm not talking like $200 cheaper, i'm talking more than that. after the h22 is swapped, basically i plan on swaping out the intake manifold for an accord euro-r, exhaust for a turbo manifold ... i'm going to do the swap by myself / with a few of my buddies.

 

the front clip/lsd is what jackingup up your price. you probably can't even find just the motor with lsd for less than 2500 not including shipping. as far as posting another thread in the fi section, he was just saying check out the compliants and experiences others have had with that manifold. like he said, you get what you pay for. it has worked for a very small amount of people but it won't hold if you plan on making big power. its best to leave it alone completely. i wouldn't use it if it was given to me. i like the design but the quality is a piece of sh*t. but your best bet to asking turbo questions is in the fi forum. also if you plan on doing the euro manifold plan on doing mods to make it work. check out 2point6's euro manifold write up in case you are unaware of whats involved.

 

thanks for the advice. yeah i've already got 2point6's euro manifold write up book marked in my favorites. well the lsd that i'm buying extra with the clip is only $250 more, which isn't a bad deal. I heard that the ssac stuff is crap, but from what i've been told, it's because stuff isn't properly supported. if you fix that, you can have a decent manifold on your hands ... that's what i've been told. i'm going to go with the "ram horn" style manifold ... just because i know it's a better manifold.

 

Just out of curiosity why did you decide to go H22 turbo instead of F22. On stock internals I think you could get more power from the F22 because you can boost around 10 psi instead of 6 because of the sleeves.

Just curious why you made the decision and what you are going to do with the F22 if it is in good conidition. Don't let it go to waste.

 

i'd go h22 boosted over f22 anyday. built wisely and it will out do the f22. i know the stock sleeves are in question but there might be a prayer yet. check this thread out.

keep up with this thread guys. it would be nice to know that this option really really works. if it does, resleeving the h22 may be history because most of us might boost 10-15psi daily anyways. my goal would be no more than 15psi so this experiment that is in the works might answer prayers to alot of us. saving 100's of dollars. enabling us to place money towards other upgrades.

anyday... with an 'emptier' wallet.

 

Right, I will not argue that if you boost the same on the two you will get more power from the H22. But it takes more money for the H22 to handle that same amount of boost. It all has to do with budget but for a non outrageous amount of power for a FWD vehicle I think the F22 will give you everything you need and at a cheaper price.

 

u cant use that first manifold unless you change the radiator and maybe even the crossmember

 

originally I wanted to go boosted f22 ... i had my heart set on it. i'm looking for roughly 350whp and that's about it, maybe 400whp, but i think that's asking to much outta the f22. when i asked if it was possible to get 350-400whp outta the f22, people basically laughed at me and told me to go with the h22 ... "it has more potential and yada yada yada." plus the parts for the h22 are much easier to find. i think i might start looking to see how much it would be to build the f22 up nicely. with the money i'd save from doing the h22 swap, i could buy forged pistons, rods ... and still have some money left over. does anyone have any suggestions for a manifold for the f22b1 engine?

You should be able to fit it in there with just a civic style radiator off to the side, totally worth it for that sick manifold.

 

yeah that's what i've read ... all i need is a civic style radiator and the manifold should fit ...

def worth the read ... just because of that thread ... i'm def gonna have to go boosted h22

 

Merry Christmas and Happy Holidays!!!

I have a question about the LSD that comes in the JDM h22a prelude trannys. Would I be able to pull the LSD unit out of the 5-speed h22a tranny and put it in my 5-speed f22b1 tranny? I'm curious because I know that longer gears are better for boosted engines. That's why I want to be able to try the LSD in the f22b1 tranny too. Cause if I really don't need the h22 tranny, I'll just buy an h22a engine and use my f22b1 tranny and get the other parts to do the swap. Let me know what you guys think ...
