E85

 

Cams.
E85
Beehive springs
Arp head studs to boost 30psi or more.

 

Sorry guys forgot to mention we dont have e85 in my country although wish we had but thats not poasible

 

My current turbo is a kinugawa 20g from ebay the turbo is running good at 23 psi 98 ron .will i see significant gains if switching to an hta73 green or any similar size turbo on pump gas

Best deal for the $$$$$

Green won't get you much if anything compared to what you have.

 

I would say, injectors, cams, or an FPGreen/Red/Black turbo. Maybe a coil on plug setup to smooth things out and add a little hp.

How long have you been running your 20g?

 

Or fp red

 

Boost demom the 20g came on the car when i bought it so its been running good for a while it has an 8 compressor housing as i can see not a 9

 

budget and purpose for the car?

 

roll racing and highway pulls as for budget nothing too extreme not willing to build the block

 

it seems going with the fp red and gsc s1 or s2 cams + injectors is great setup on pump stock block for low 400-430 whp

 

I've never run, or been in a car that had an FPBlack, but that may be the way to go for roll racing. I thought the boost threshold on the FPRed was perfect for the street and limited drag racing I did. I've seen that the MHI housing made it pretty close between the two, but someone else would have to chime in.

 

my car came with an fp red at 564 hp and its fun I know it has more to it so once I make a few changes ill have my shop retune and see if we go 580-600 but knowing me it will come off for a 6466 like my old evo for 700+

 

<br />most of the roll races we do are from 2nd gear roll we dont have crazy fast cars here so running 450whp-500whp that would be considered a really fast car if you know what i mean for that i think the fp red would be enough or am i wrong?
