Not the 12's unless the turbo kit comes with fuel upgrades(fuel pump, bigger injectors, fuel pressure regulator and some sort of AFC not including the missing link). Than there is the exhaust system you will be needing because the stock exhuast is restictive. Than there is tuning. Good price on the motor build but I don't think you can get a fully built 420a for that price. Maybe a short block. So, honestly how much have you put into you 420a-T to get 214hp and what are your mods.
Have you got a chance to run a slightly moded 4g63t? If not would you like to run one?

You can include those costs with the turbo kit. Walbro 255 is about 100, SFMU (which you can tune with basically) for about 200-300, injectors (He recently picked up some Accel 30lb injectors for $40) are about 200 brand new if you can find a deal. Missing Link or FCD is roughly 20-40. Can pick up a Tsudo 3" exhaust for 200-300 shipped (basically Apexi N1, but better). Motor build all you need is lower compression forged pistons and some rods and you are in business. It has been proven to handle 15+ psi with just those. You can get those for around 1000 and if you install them yourself, you can save some money there.

Yes we have run a slightly modded GS-T. His brother is running 15 psi and we can both beat him. You all say you aren't talking down the 420a, but really you are. I agree that the 4G63 is a good engine, great engine actually. It has been proven time and time again to take beatings and come back for more. People assume the 420a has no potential though because it originally is a NT engine and made by Dodge/Chrysler. If me personally had about 5-6 grand and I could either get a RS/GS or GST, I would definitely go with an RS/GS. Besides the fact that DSMCrazy's bro has had numerous problems with his GST and my cousin as well just had his GST (with brand new rebuilt 6 bolt, brand new EVO3 16g, etc.) shit the bed, I really don't want to take my chances. Also, you can't really find a GST for under that price that is in good condition as you can with the RS/GS. If you can, that soaks up most of your cash because it will probably be right around that price. You can find many RS/GS's around 2-3 grand nowadays if you look hard enough, I know you can down here easily. That leaves you with that much more to spend on upgrades and maintenance if need be.

Sorry I typed so much, just trying to get my point and views across to everyone.

welcome to the site! thanks for the info! how much boost can the block hold thats what i am woundering the most, forged internals are in the very near future along with some crane cams i know they can handel tons of boost but will my block beable to!

You can find most of these answers by visiting 2gnt.com and DSMTuners in the 420a section. Do a little researching and you will find more info than you can stomach haha. These are both great resources for info about our cars. Make an effort to do a little searching before you post though. Most of the guys on there are very knowledgeable and have probably heard your questions a million times and get a little aggitated when they have to keep repeating themselves.

Each motor is different. Most people don't go over 8 psi, and that's with a 12:1 FMU and walbro 255 on stock injectors. With upgraded injectors, S-FMU and the walbro you can get up to probably 10 safely(granted compression #'s are good) but that's still considered pushing it..

Not the 12's unless the turbo kit comes with fuel upgrades(fuel pump, bigger injectors, fuel pressure regulator and some sort of AFC not including the missing link).

Like total said the walbro 255 is normally what people go with in the kits and they aren't too expensinve. Also that deals are availible for injectors for not much and the S-FMU is a common purchase when going turbo. Especially for those with serious plans of rebuilding.

As for the AFC, that's what MSnS is (Megasquirt and spark). That's the tuning program that nearly all big powered 420a's are running. As for the actual tune, it doesn't take a rocket scientist to use megasquirt. There is the megasquirt forum as well as the 420a management forum on DSMtuners to read up on, not to mention 2gnt.

Good price on the motor build but I don't think you can get a fully built 420a for that price. Maybe a short block.

Well the 420a head was designed by Lotus, and is much newer than the 4g63 head. Not much really needs to be done to the head...Not for a good while. Hahn reached the 11's with their 420a running a completely stock head.

So, honestly how much have you put into you 420a-T to get 214hp and what are your mods.

At the time of my dyno my mods were:

Garrett/aiResearch T3 60 trim
Ebay manifold
2.5 turbo back exhaust
12:1 FMU
Walbro 255 lph
2g SMIC

6 psi

As for money, now I've probably put around $3000 total(mods) into my car, that's just a rough estimate though..

People are just saying that the 4g63 is a better bang for the buck. You can make over 450whp on stock internals. Save the money for the rebuild and just upgrade to a Tsi, not to mention you could go AWD!

There is nothing wrong with the 420a, the 4g63 just has more possibilities. You could put down 214 whp with $300 in mods with a DSM.

Show me a 4g63 putting down 450+ at the wheels with some proof it's running stock internals..

As for the second part... Re-read what you typed...

He already said he's working with what he's got. The 420a.

PS: Stick with the 420a

stock 4g63 record, 585awhp, 10.5@133

also, a fellow on this very board by the name of Nash had his stock motor'd daily driver talon up to 550whp for years.

You're kind of rude.

If he wants to stick with the 420a, good for him! It would be a good project! But as they have ALL said so far, 4g63t is more bang for the buck simply because you can pay less and get more. Its like Target! Persoanlly, I don't think any of us would buuild a 420a, but hey to each their own! All I'm saying, you might as well be building a Neon! I should know.

There have been numerous 4G63's that have put down 450+. Sell your car. Oh yeah and don't get too mouth buddy, we don't know you.
