the crank will be fine.....
the rods and pistons are forged they are fine

a more main concern would be rod and head bolts wink.gif

Ever thought about gaskets? About Valve springs? About main/rod bearings? About piston rings? or you think REALISTICLY they will hold up.... Yea, they will hold up 1000 or another 500 miles but after this?

The main thing on ANY setup is Tune up. You can get HIGH hp's on ANY stock engine with turbo setup, the main key is TUNE UP. Perfect ignition/air fuel mixture - perfect EMS, and you are ready to go.... without this - you can put any forged stuff to your engine and hope they will give ya high HP's, but if your setup wount be running good managment system no forged stuff wil help...

[quote=dans_st,Jul 11, 2005 - 2:39 PM]Thanks for your help guys, i just bought some RC engineering high impedence 550cc injectors for an integra type-R they should work fine I just need to find the clips to wire them in.

Also I know that this is way too much fuel for a 7AFE my engine also has a turbo so it isn't outrageously too much fuel as it in right now-BUT i can turn it down with an stand-alone EMS and i will be needing more fuel when i get all of my mods done. at which time my engine will be basically a 7AGTE and have more fuel needs.

RC says that the injectors I need are SL9-550's which is the same as an ITR And I don't need a harness or clips

what? ok so you found the injectors you need to fit your clips

ok so...... those injectors are big time over kill on your stock 7afe also big for a 180whp 7afte what is your power goal again? yes you can control your injectors with a standalone ems you might have some idealing problems but a good tune can take care of most of that ("i will be needing more fuel when i get all of my mods done. at which time my engine will be basically a 7AGTE and have more fuel needs.") what all are you doing are you going 7afte or 7agte because there is no basically the same there those are 2 way differnent heads and flow rates so can you clear some of this up wink.gif

" my motor will be the fastest out there because i will have forged stuff in it!!!!!!!!!!! and ill be running a lot of PSI !!!!!!!!!! "


thats basically what youve been saying for a few months now.... what i never hear tho, is what kind of hp goal you have for the motor? you know, different turbos make different power. what wheel hp goal do you plan to reach out of an econo motor that can barely hit 100hp in its stock form?

dan your getting SL9-550's
where did you order from?
and did you talk to RC yourself?
what was your crank hp goal for them?

with about a 250-280 crank hp goal
i think i came out with like 525-550cc injectors
via RC's equation

I spoke to a few honda/acura people I know and found out that the IT-R was a saturated(high imped.) injector , then I called RC and talked to one of thier techs and he said the SL9-550 was hat fit my car as well as the IT-R with no mods to the injectors, I ended up ordering them through racingdimension.com for 305.69 shipped for the set.

NIK-as for my plans for my engine it is currently a 7AFTE I have a set of ford probe turbo injectors right now and I know that I need more fuel therefore I bought the 550's knowing that as soon as I can put it together I am going to go the 7AGTE route- right now I am working on sourcing all of my parts. as far as what mods I am planning I want to do the a 7A forged bottom-end with 84mm 4agze low compression pistons, for the top end I plan on doing a 4AG big port head with full P&P on everything up top, and possibly going with larger valves anh HKS cams. as for turbo I'm not sure the largest while not having too much lag with alchohol injection.

my machine shop told me I could do the 84mm ,but i would definetely need a new radiator or it would overheat. I haven't personally seen it done have many6 of you guys seen problems with a 7A block with this size pistons before? I don't want to seem as though I am a know it all if I have that is just what my research on this has led me to believe that I can do this - but any and all help is appreciated.
I rebuilt this engine last year and that is the most I have been in the bottom end I know NIK and Player158 have been into the internals and I am all ears to you guys' advice

i haven't personally done internals yet i'm still researching the most beneficial setup......and i don't think any has ever done 84mm in a 7afe you would be the first person to try that....

so if you try and it works thats really awesome we would know much more about the strength of the block...
if not then we know how much that it can take and how much it can't

Player158 i dont think has touched his bottom end or even started building his motor maybe gathering parts but thats it

As for me i tore my bottom end apart bored the block new custom pauter rods and 4agze 8.0:1 pistons and had it all balanced i have a bunch of new pic on my camra but havent had a sec to download them yet because i'm in the middle of moving.

you could probable bore it to 84 mm and running it but theres no telling if 1000 down the road you have problems with it plus if you boost your putting that much more stress on the block or it could be fine no one here knows the limit to the block at least that i know of. the highest hp reported on a 7a bottom end is 300 by ray hall 7agte 20v

I on the other hand i will be pushing for atleast 350 whp or more but i did minium boring i have been told by my shop that its better to have more there (metal) on the block for stress etc preposess i believe them they have a talon awd drag car that pushes 832 whp will just have to find out

whats your power goal again?

I don 't neccesarily have a power goal, I just plan on using the best parts I can get, with hopefully the best equipment (block/head) i can put together then just put it on the rollers and tune it and try to get the most I can without spending radical amopunts of cash. my only real goal right now is to get into the 13's on the quarter, then if I can do that and there is room for improvement I will try to do better and go faster. I am also trying to build a RB powered 240sx that I will take to the track but as of right now my celica is my car I drive daily and cruise on the weekends and I just want MORE power from it.

As for the 84mm pistons I am going to do some more research o9n how big I can go and keep reliabiltiy- thanks for the advice if not I would probably have jumped roght into alot of problems down the road- so I'll do some more research and see what is possible and best for my needs

Which is why I was thinking the other day... Arent 4age cranks stronger than 7a? I know the 7rib block is probably twice the strength... and rods can be had cheaper. Would a built 4a not be safer than a built 7a?

Overall, I am very interested to see how Nik's engine turns out.
