RA gear sets are not all that much stronger, that's a common falacy in my opinion, if you want to hold the power either stick with the stock 5 speed and take it easy, or you can go to a straight cut 5 speed 1-4, and a helical 5th, this is a better setup for the track, the 6 speed is fantastic, and i did the swap in my old wrx, but the 1-2 gearing is pretty tall, it holds a ton of power though.

PPG may be a good contact for getting stronger gears for these cars and Geoff at Full Race might be someone with good contacts too. He makes great manifolds.

Geoff is on this forum from time to time too.

virtually nothing for the block/machinework/install. paid for the turbo, fmic, intake etc etc



That's what I thought when the builder was explaining it to me. He was soo excited about the block that I think he just kinda left some details out but he was explaining to me more about the different method of detroking than the traditional methods using different rod length?...i'll be down in the edison/nj area today so I'll get some clarification...

what would you recommend? I do LOVE my 5spds but the added strength a 6spd offers might be my only route right now... ra gear set too close?

Stroke is only affected by crank throw. Changing the rod length doesn't change displacement volume.

For gears, contact Andrewtech about a PAR set. 240-683-1000

What is the projected performance gains from increasing compression?

We've got boosted guys with low comp tubro'd Honda FC20 motors still pushing 9K with 9.8:1.

fightinchunk 10-18-2012 09:27 PM

bac can probably explain it better... but I believe the gains aren't what i'm looking for... I'm looking to maximize the area under the curve...

If you're looking to maximize the area under the curve then you ARE looking for gains, probably through all rpm ranges. If this is the case a 20g twin scroll setup would be awesome, a single scroll turbo will still take a little bit to spool even with higher CR.

Yea, I've that name before too, are they in the northwest ?

This forum needed something new and different.

Subbed for an interesting build.

Northeast/Mid-Atlantic

In MD.

12 Minutes from me. With them is TurboXS as well. I love Gaithersburg =D

lol i might have worded that wrong... if I put all this money into the car I certainly hope there would be some type of gain! but I meant that this wasn't going to be a high horsepower build that it certainly could be capable of with e85/c16 etc... but that i'd be look for a well rounded, effecient motor that would be fun throughout the powerband that may or maynot blow my trans to bits.

I currently have an EJ25 hybrid with 2.0 heads. Entirely stock internals except for 14:1 forged pistons. Runs on E85 and using an FP green. Car makes roughly 390 WHP and WTQ. Boost comes on at 3000 rpm. Running 21psi. The car is an animal! I don't consider 11:1 to be anything high. I previousle ran 10.5:1 in the same configuration but with an 18G and made similar power but higher boost. In the future I will use better heads and a 30R and see what happens.

Did you use E85 in your 18G setup or pump gas?
