well I´ve been drroling lately after a turbo. go to topics on the right go to turbo and check out jess´s great article on how to slap one on. you should be around $2K for the install and with the right tuning should top out about 250ish. this should work fine on a stock BP. you should do a compression test first to make sure the valves are in decent shape.

Other than that your looking at a bigger turbo and a stand alone FMU. Haltech is the most popular. BLT sells the custom header, turbo and haltech if you want to go bigger. look in the $3500 range for that plus building the engine from the ground up I think you could snag 400HP without to much trouble. you can probably do it on a stock BP but its pushing it. you are also getting beyond the limits of traction and tranny. look to beef up the tranny as well as a LSD to go with it.

What is stroking the motor? I thought that that was making the stroke longer, and if that was it wouldnt that give you higher compression and dont you want lower compression for a turbo? I dont know so thanks for giving me the ld. ;-)

Yes it´s making the stroke longer. Theoretically it would increase compression ratio. If you´re running a turbo setup properly tuned you can still run a pretty high compression ratio too. High compression+turbo=big HP.

Anyone who doesn´t run premium in their turbo car isn´t very smart anyway, so of course if it´s high compression AND turbo you´ll want the best gas you can get. Running anything less than premium you´re just asking for trouble. Dunno if you saw it but SCC turbo´d a toyota matrix and they are 11:1 or 11.5:1 compression. They had no problems running it on pump gas.

The problem with a high compression engine and a turbo is only evidenced by the knocking. The real problem is cylinder temperatures climb into the stratosphere and that makes burn ignite to quickly. Not a huge problem in a stock engine, but with the extra pressure bearings, wrist pins, pistons and compression rings all scream bloody murder at top dead cylinder when the pressure is really high. If you’re lucky the head gasket blows and saves you from doing anything stupid. You run into the same problem with a nitrous setup. Only when it pings, it just blows things to pieces.

Yeah sleeper...they didn´t have any problems until they cracked the number 2 or 3 piston head on the "trek to texas" I remember that article. :-o

sorry to replay so late:

Stroking....increasing displacement by making the stroke longer. It requires a new crank, rods and pistons. if its done right you wont change your copression. EGT´s run 9:1....that´s okay for a turbo. Most turbo motors are 8:1 or around that. So, with 9:1 you´ll get more bang for your pound (psi). Go much higher then 9:1 and you wont beable to run as much boost.

EGT stock internals are forged. (lucky us) Many of the turbo guys run 10psi easily. I´m aiming for 15psi on race gas 8-10psi around town.

Fresh rebuild can help, but if your going to rebuild remember to do the extra work on the head.

On the head switch to sodium exhaust valves. They wont melt under the heat from boost. High quality (felpro) valve seals are a good idea. New springs so you can get those valves moving at the speed of light. Overall just making sure the head is cleaned up is good idea too.

if you want to go all motor without shortcuts of N2O or boost...you want higher compression and stroke and bore the motor. cost of motor work would be around 7k probably.

a twin turbo setup on a car with such little displacement isn´t worthwhile. You guys watch too much fast and the furious. Twin turbo doesn´t mean shit. Why are all the toyota and rx-7 guys switching over to a single turbo setup? hmmm... blade summed it up pretty nicely, I belive wiseco makes pistons for the bp engine? I may be wrong... but some company does.

I just sat here for like 10 minutes trying to figure out how stroking the motor wouldnt give you higher compression and i couldnt figure it out. I know it is basickly making the cylinder bigger but ahhh :-Y , could someone please explain this to me and also what are forged internals?
