lol agreed

 

If I were you and wanted to make 100 hp more without changing the turbo I'd go with gsc s3 cams, map o2 dump, e85, a ported intake manifold throttle body and a tubular exhaust manifold. That should be able to get you close to that and also keep you in the 2k range if you buy some parts used on here

 

In VDR just add 1000lbs to the weight of the car. Done.

 

First of all thanks for the great Ideas and opnions guys.
I'm out of the country and kinda busy this week, keep up with your good ideas - The moment I'll have the chance I'll get over the thread and answer all of your questions.
the fuel is 100 octane.

 

s3 cams and a o2dump and like 2000cc injecters and race gas and you should have it. the cams and the turbo are the limiter right now

 

Agreed.

OP you dont seem to have a very organized route as far as making this power. Change your fuel to make your set up more efficient or change your turbo to get more air fowing

 

I would leave the FMIC for last. Star with a E-85 conversion, MBC, 3"TB exhaust and a custom tune and you should be just there on the 100 whp.

I don't think he will be close to gaining 100whp from e85 and a retune, you might want to read his post again

 

magnus intake manifold, bigger cams, ported head - maybe.

 

It looks like there is one opinion - E-85!
I cant really get the most out of the parts unless I change the fuel system - I'm really surprised that going over 500 HP has to include the e85 system, I took it in consideration but thought it is going to be the last thing I'll do.
Another question what about the OEM engine? how much power can it take - dont forget I said reliable- very important, still its a DD car!! so maybe what "scheides" suggested is the right next step, what do you think guys the OEM can bare that abuse - more than 600 hp on stock engine??

At the moment I'm thinking about CBRD/JMF TwinScroll Manifold and their O2 Housing - after reading what CRBD says regarding the O2 housing they claim :"Most External dump designs are improper and cause boost creep at high rpm and load" what do you think about that - map o2 external dump or the CRBD o2 dump or another dump that you suggest? (the money is not an issue looking always for high end quality parts)? )
dont know really why but till these thread I always considered AMS as the best brand ever - guess I was misleaded by mechanics.
just to make things straight:
turbo - not intending to change at the next 6 months at least
cams - wish I bought the S3 instead of my Kelford's 272
engine build- depands on your answer, if the stress of putting so much power on the stock than I'm not gonna add more power and rebuild my engine - this is the most important issue at the moment!
e85- not at the moment
Intake manifold and TB- This is what started the thread - I wanted the Ams f1-I talked to a couple of mechanics including AMS and it was agreed that its too early for that- and I wont get the most out of it at my current setup, same about TB.
Injectors - thinking about the 2000cc any suggestions? what else do I need in order to make them work - pump, fuel rails or a race fuel? if it's the last I'll pass on that- logically why would I add more fuel if I dont add more air(bigger turbo)- my 20G is almost on the edge considering reliability needs.

SO, at the moment I'm thinking about:
GSC S3 cams
CBRD Big O2 Housing/Downpipe Combo
CBRD/JMF TwinScroll Manifold
Good tune
what do you think will I get another 100?

Thank you very very much guys I'm learning a lot from your answers, just want do it right and make the most out of what I have.
sorry for being annoying

 

You are not going to get another 100whp from your current turbo, it just is not going to happen.

GSC S3 are a good option since you are looking to make high power.

I wouldn't waste money on the CBRD parts, you can find better alternatives and parts that are not priced sky high because they look nice. The price of just the dp/o2 combo is in the upper $800USD range. That is half the price of a turbo right there.

A good tune never hurts but you must remember that once you go over 400 torque you are risking blowing the OEM block because the rods cannot handle it very well.

To make an additional 100whp you need some magic dust or to change the turbo.

 

You are not going to push another 100whp on the stock block, you are already at the limits, what's your powerband look like? Where is torque at?

 

race gas dont require huge injectors like e85... you can make 600whp on 1000cc injectors and any race gas c16, 100, vp import

 

550 on a 9 20g? nice.

 

they claim :"Most External dump designs are improper and cause boost creep at high rpm and load" what do you think about that?
evo 8426 - can you recommend on some parts/brands?
Some of you are saying just switch the turbo but that is simply not enough - rebuilding the block at this point is just inevitable - cuz I really dont want to take the risk of cracking the block!
I thought the block could handle the extra power but looks like it aint
any suggestions for parts for the engine rebuild?
