Put a blower on it and a decompression gasket, recalibrate with standard or aftermarket computer, or take the easy option and just drive down hills instead.

X2 on the blower I have never done one but met a guy at a car show who said they work amazing on the jeep inline 6's.

Have you looked at Clifford Performance?

Just a couple of figures for you out of our Aus Ford 6 Turbo. A mate's BFFord XR6 turbo pulled 170rwkw or 227rwhp on the dyno.

thanks!but i don t want to fit a blower on my jeep i already have a lpg conversion on it and the underhood space is already thight .i think a high compression engine will work better on lpg cause lpg has a high octane rating..what do you think?

[fab1969]

hi! i could have fit a turbo cos my dad have plenty of knwoledge on turbo conversion ..but i d like to have stock looking engine with more displacement and higher r.c. ratio .i got a lpg conversion so i can push compression higher with no problem of pinking ..my engine has over 210.000kilometer and has piston knoking when it s cold..

Hi . I am not quite sure which way you are thinking here, but if its miles per gallon you are after, then a standard engine is probably your easiest solution.
Cheers

i m looking for a torqueir motor tha s the reason why i want more cc...furthermore with lpg you loose 10%power and torque .. i need a more responsive engine down low . the reason why i fitted lpg is partly to reduce fuel expense and in italy where i live we also pay less for road tax ..if you are a gear head like me you should also know that lpg has between 105 to 108 octane rating so if you increase your engine c.r. you get more torque and better fuel economy cos you don t need to downshift so much on the hills

How much are you paying for a litre of unleaded. We are paying $1.45 per litre here and i have tuned my 347 to run on 93 octane. LPG here is 70 cents per litre but i dont think it is rated at 103.

we pay between 1.92 to 2. euro for 95 0ctane unleaded.2.12 for 100 octane shell v power.and over0.92 cents for lpg..the octane rating on lpg depends on the amount of propane it contains...
