what can i do to the internals to stand 350hp.my compression is now 11.8
 
change pistons to forged low compression pistons, if you want 350whp change to a b16a block and get forged rods also, if you want 350bhp then the oem b16 block and rods with forged pistons will be fine.

obviously you will need supporting mods like an adequate fuel system, clutch, exhaust, etc...
 
Also add, a new ecu and proper tuning.
 
cant the stock rods andle 350hp. a ticker wont solve the compression problem? what is the normal compression of a stock b16b in paper is 10.8 but i have 11.8 and i dont now why just bought the engine like this from tigwa
 
Sounds like your engine may have been N/A tuned if compression ratio is that high....

You will want considerably less compression to run enough boost to make 350BHP....

You might want to budget for considerable drivetrain/transmission upgrades for that target power too:shocked::nice:
 
i have my old block b16a2 but its broken crank and rods will help?

Seiing as you are aiming to almost double the standard horsepower & massively increase torque....the standard components will be put under massive strain:shocked:

Id advise uprating them if you want the car to be reliable!:nice:
 
I would of thought transmission would be fine. High powered FWD cars put alot less strain on the transmission components.

The wheel spin you will be getting in 1st and 2nd gear will take most of the strain. Once in 3rd there is less stress anyway. The think i would probably concider is obviously a capable clutch. If you have the money a good diff too.

As already said, compression is definietly on the high side for high boost aplications. What turbo are you planning on running? For that power a Garrett GT30 would be nice. Or a GT2876R on high boost would probably get that figure but i would go with the 3076. And to minimise lag go for a smallish hot side.
 
a gt2871r will flow up to 400bhp @ the fly with a .64 housing, and would be very repsonsive. a .86 exhaust housing will flow more but will be laggyier. it all depends what the cars going to be used for, for a road car you ideally want a turbo thats going to provide good mid range so a gt3071r would be a good compromise for power and drivability, you wont want to go too big otherwise you will end up with a car thats only good in a drag race and no good for the twistys (which these cars are all about :drive: ) but it depends what you want... :)

also i would have said the gearbox will be under more strain in 3rd gear up as the torque will be going through the box at that point, where as 1st and 2nd is likely to be lighting the tyres up.

my car is for fun only , street race some tymes . i think b20 block will be best stock to do arround 350bhp the turbo is this T4 TURBO .60 1.05 . dont now if its good or not, i want to keep the a/C

is that not one of them cheapo hong kong jobee's? bet it has probs with cracking with all that weight of the turbo and no bracing

The manifold is made out of SUS304 Hi-Grade Stainless to help disperse heat. This manifold is drag-race quality, and similarly design manifolds can be found on professional drag cars. Manifold has flange for an external wastegate.

dan i worded wrongly.

I mean the spin in 1st and 2nd would take away the strain on the transmission. By 3rd gear the engine wont use as much of the torque and due to the high speed the pressure is no as much. My 3sgte starlet never suffered gearbox problems and that was with 310lbs torque. And i had no fancy buisness at all. Just a bog standard Celica N/A box with a custom clutch
 
i would have thought the stock box is pretty strong in fairness.. most things jap are usually over engineered (unless its a gti-r gearbox :p ) you could always get the internals strengthened if you do get issues with the box, but i doubt that will be the case. like dan says, being fwd its not going to be under as much stress as a 4wd would be.

think some research is needed on your part buddy :p do you really think a £200 manifold is going to be good quality? the phrase 'get what you pay for' suddenly springs to mind here... plus it being made by XS POWER... well, need i say more? :secret:

Yes the stock rods can handle 350hp, nobody makes a head gasket thick enough for such high compression (2.5-3mm!!), contact tagiwa and ask them want is in the engine that makes the compression so high.

And yes the manifold/turbo/wastegate pictured above are 100% JUNK!!!

also if your planning on running a turbo, running the OEM flat top pistons is not the best idea, dished pistons are much better and will retain some 'squish' in the combustion. and like said above, you will need a THICK head gasket to drop the cr to a decent and safe level for any decent boost. im sure you can get a custom gasket made though..

He is gonna need a 3mm head gasket, that is .11"!! That is pretty damn thick man, thats really going to throw things off and its really the wrong way to go about it.
