I hope you don't plan to put those Forged Pistons into a stock block.....?

The cost of rebuilding a trans, keeping it in stock form, will probably cost way more than what you can pick up a used Trans for that's still good..

Unless you're doing something special, I wouldn't rebuild it.

Well one of the synchros on 3rd is bad, whenever I try to shift down from 4th to 3rd I have to be gentle or else it'll try to grind on me. I'm not paying anyone to rebuild the trans, my dad owns his own shop and lives about 2 1/2 hrs away and he said he'd just get a complete set of synchros for the tranny and he'd help me replace them.

Is it bad to use forged aluminum pistons in a stock block? I'm mostly looking at the spec sheet for the JUN Prelude on their website and according to it the block hasn't been bored nor sleeved and the crank and rods are stock.

If you think i can get the JDM lsd tranny and it be better in the end than rebuilding my trans I'll probably do that since a friend wants my H23a1 to put in a smaller Honda and use it for autocross. I guess I can sell him the tranny along with it since he probably wont be shifting from 4th to 3rd.

Well rebuilding it shouldn't be a big deal then and might be worth it. It will at least hold a decent value with new synchro's if you decide to sell it later.

lol, Bad? It's not bad. It's wrong. If you do, you'll destroy your sleeves. The H-Series Block uses FRM Lining in the Sleeves. You can not run a Forged Piston in the block. Unless you get special coated pistons from Mahle.

You're looking at the Jun Website at their Lemon Prelude? They're not going to list every spec and change to the t. That site definitely isn't something you should be using for or counting as "research." Check H-T, there's TONS of useful info there that should educate you.

Hmm, well I'll have to rethink what I'm gonna do about the bottom end, I want a strong, light piston to try to increase engine response. I was mostly looking at JUN as an example, so many people claim that its hard to reach the power they did while N/A. My main concern with the tranny is will it drop outta vtec when shifting up through the gears because of its taller gears? Or will this tranny help the car achieve a slightly higher overall top speed?

MLBZ521 · 03-16-2009, 07:55 PM

The Longer Gears will give a Higher Top Speed, but will you ever reach that top speed is the question. It'll depend on what you're doing.

It's not "hard" to reach it.. Just requires the right work and parts combination.
High HP Naturally Aspirated has been done before, and can be reproduced.

What's your goal? Is the first question. There are a few builds that can help point you in the right direction..

I have a Fully Built NA Block that's capable of 300whp and running 11s. Check the thread in my Sig if you're interested in it.

I mainly want a streetable N/A car, i would be perfectly happy with 260-270whp, if I feel like it though having it competitive enough to go auto-xing with my friends. I see the prelude as my reliable DD while I wait till i have enough money for either an FD3S or S14(or even 15) to really have something fast.

MLBZ521 · 03-16-2009, 08:28 PM

To really have something fast? What're ya trying to say, huh? :P
The Prelude can't be fast? :P

And with 250whp++ that'll be quite a build to hit that.. Definitely won't be mild.

Here's a good one for reference.
my 252whp h22 thanks to RLZ and RMF - Honda-Tech

I got a couple more that I'll find a little later..

Wow, I stared at that car for hours last night...
Hopefully I'll have enough money after the H22a swap to toss an LSD in this tranny while it's out of the car.
I meant more like I'd eventually like to get something RWD turbo, I'd never boost an N/A car.
