Howell 2.2 stroker kit? How much hp from it?!!!

[special_K86]

I'm planning on getting the 2.2 stroker kit from howell automotive, but just out of curiosity how much hp would that kit give you?! I'm going to be doing this before i go turbo so i won't blow the engine. But i'm just wondering what the kit will give you alone? Thanks- Kevin

The HRC kit will give you 260-280 at 10 psi all the motor will allow you to do is run more boost. Yhe hp will very if it is bored and by how much remenber the 2.2 whit out being bored is only 10% more displacement than stock. Hp will also depend on what compression you go whit.

oh, ok. Thank you for the info.- Kevin

I am having the 2.2L stroker block from Howell. Figure that it gives you 10% more displacement so right off the bat you have 10% more hp and torque. And you get the displacement from 2.0L to 2.2L by modifying the crankshaft not by boreing out the engine. If you are going with the turbo kit then get the 8.6:1 compression pistons with the motor and you will be more than happy.

If you got the 10.5:1 or 12.5:1 pistons you'll feel some definite increase but if you dropped your compression to 8.6:1 without any other big mods (IE: Turbo) then you probably won't be able to tell much. The overbore and longer stoke will get you some power and help the turbo spool quicker but anytime you lower your compression you're going to lose power.

Yeah you will gain power but not ALL that much. Figure it this way, with the 2.2L stroker you get 10% more HP and TQ, by droping one comp point you loose about 4% of that 10%. So that's still a 6% increase, but figure also that eash mod you do will also be about 6% more effictive.

basically with out a built top end: valves, cam sprokets, cam shafts, rollers.... basically a built up top end to match the work to the bottom end you will hardly feel a hp increase. after the top end is done is a different story.

That's not true you will notice the bigger displacement. You won't need headwork till your up in the horsepower range. You could always use the work, but your head flows really well, it was designed by lotus...

yes, you will feel a difference, but it won't be a huge difference. will you feel a difference?.. yes. will you feel a $3,000.00 difference?.. NO! that's bacically what i was trying to say.

I agree with you there, if you buy it only for it's power increase then that's not the best mod for that kind of money. If you are doing supporting mods to build some power though, then go for it.

I am planning on going w/ the star stage 2 kit. How much psi can i hold? Thanks- Kevin

 

[RACER-X]

well your going to need more then just the built bottom end. you need a fuel system and valves, cam shafts, and sprokets would also make a big difference. but going with the strength of your bottom end i would say 20psi shouldn't be out of the question.

 

[dsmrunnah95]

If I'm not mistaken that bottom end can handle all that that turbo has to give. Eagle Rods and JE Pistons are made to handle around 600hp but you have to make sure you top end can handle it.

18 max on pump gas and that's well tuned with enough fuel!!! more over i don't think the guys are going to feel a WHOLE lot more power except in the higher rpm range, and even then overbore a 2.0L and you'll be happy. Just my experience but I don't personally think it's worth the money, the gains just don't seem drastic enough, now 2.4L that would catch my interest for sure.

 

[Kirby]

You don't need the top end touched to run 25psi of boost on the T3/T4. The 420a head was designed by LOTUS, LOTUS!!!!!! you don't have to upgrade a damn thing. It would help the motor breathe a lot better but you do not "HAVE" to mess with it for quite a while. You don't need valves cams or cam gears, they are all nice to have, but you all make it sound like if you don't do all that stuff then something will go wrong and that's not the case. You could run 25psi on pump gas if you pull some timing. Head work is nice to have but it's not required to run some serious power. You are going to notice a difference in power with the 2.2L a big difference. If you were staying N/A and you got the 2.2L in stock or higher compression then you will feel some serious power from that mod. At stock Comp. the 2.2L will make 10% more power, 10% you are going to feel that. If you raise comp. it will give you even more power. If your going turbo and drop compression, that's when the power gain is a little less noticeable, But the gain you get in turbo performance is worth it.

once again, i wasn't trying to say he needs the head worked. yes, his car will be fine and run well with his factory head and internals, but to get the full potentinal of the turbo it is necessary to rework the head and upgrade the internals. i mean put the supporting mods with a turbo and the hp gains will be a night and day difference between a modded head setup and the factory head with it's internals. i would venture to say 50hp+ without tunning. well, am i right or wrong.

 

[special_K86]

Well to solve this, i am going to be rebuilding the head, but it won't be right when i get the turbo. But with rebuilding the head, besides getting more hp, will it help with pushing more boost. I'm going to run 15 on the road, and when at the track, i'm hoping to run 20 and even if i can 25. Thanks for helping- Kevin

What if i was to get the Howell rebuild kit with pistons with 8:6 comp. ratio will this make my car slower until it is turboed? why dont they sell the stock comp ratio (isnt it like 9: 6??) And if i went with 10 would that put turboing out of the question?

Ok, No you do not need to touch the head to reach your boost goals. If you do some porting and larger valves you will be faster at that boost level. The head work is nice to have, and if it's in your budget to do it now then by all means do it. But you do not "have" to do it to achieve your boost goals.

Yes, if you stay 2.0L and go lower comp. you will be slower until your turbo'd, but only about 4% slower. Yes you can go turbo with the higher comp pistons, but you better be a master tuner, or be ready to become one quickly. You can stay at lower boost levels with the high comp, and be pretty safe. But if you want to turn up the boost your going to have to tune it dead on to keep it safe.
