92 integra turbo going for 200kw....possible or not

[Mugen boy]

apon finding out last week that one of my piston has a slight pin hole in the top of it with small cracks around it i was a bit pissed, but having now decided to fill there spot with some low compression SRP forged pistons and while there put eagle rods , i will be pushing to get to the target of 200kw at the fronts, and will be doin a slight bit of porting to the head, i also plan to enlarge my currently very small exgaust.........current mods on car are as listed on bellow link

Eagle rods... No problem...
SRP pistons... Not my choice, but they'll work...
Head porting, depending on the how & the who... should help...

Things to do...
Change cams to 272deg or there abouts... (So you'll need less boost...)
Be sure to rectify cause of dead piston... (Else it'll happen again...)

piston wasnt actually cause problems but i was replacing head gasket when we came across the piston , i would have to say it would have happend when we did the 9psi dyno run , to much boost to much compression,

what pistons would you recommend? and why the cams and why less boost???

Detonation would have caused the damage to the piston...
Find out what was it's cause...
Too lean? Too much timing??? Oil contamination of inlet charge??? Too much heat... ie: Intercooler efficiency??? Bad fuel???

9psi isn't a lot... Tuned well, it shouldn't have broken your engine...
I would use ARIAS on a low budget build & SPL TODA pistons on a high budget build... $990 vs $3000...
The difference is noise, blow-bye, longlivety, reliability, resiliance...

Cams = less boost required to mack same power with std cams...
Ie: less thermal stress on engine

[Mugen boy]

that makes sense that will all be looked at while the build happens... i would exactly call this a low budget build but there is no way i will be investing 3 grand into 4 pistons , for sure the toda and there aint much better on the market for honda than toda but my choice will be between srp and wiseco, and eagle rods, possilbly and eagle crank as well but i have been told the honda cranks are pretty well bullet proof from factory

[TODA AU]

Fair comment, I understand what you're saying...
In that case, go the Wiseco's then...
Be sure your piston to bore clearence is spot-on & it'll be fine...
The Eagle rods will serve you well, just be doubly sure there are no nicks & scratches on them before they're installed... The factory crank you've got is upto the job...
Save your money on buying an aftermarket crank unless you're after a capacity change...
Best OEM crank for your application is a B18C7 crank... (PM me if you need one)

[Mugen boy]

no worries ill keep you up to date with this project should be completed in january, whats the difference between the b18a crank and the b18c7 , weight?balance?strength?

[TODA AU]

Stroke, strength, balance & bearings...

[Mugen boy]

the engine is get rebored ect, how much boost can the block handle does anyone have any answers this question for me ??

[BLKCRX]

Iv got a Melb Client with a stock GSR teg, had around 69kw standard. on 7psi we were making 120kw... and on 9psi it makes 145kw. the car is totally stock apart from the razz tech turbo kit... 200kw with more boost, pistons and rods will be easy.

I have seen you car and apsolutly love it not bein a suck up , but i am doin internals but i want to know how much boost the block can handle i want to run around 12-14psi, have you seen my setup? i want a new manifold though , have you got any pics of your car

[BLKCRX]

Here's some pics of my car... found here
