Turbo and Supercharger discussion
By Thaboosh
#78437 I have a 92 eg. Lsb18b1 swap and im looking to boost it. I got eagle rods, and low comp pistons on the way. A block guard and a nice thick low comp head gasket. I want to run a gt30 for the turbo and was thinking of 660cc injectors with 255 fuel pump.
Would chrome be able to come up with 400wheel?
What else would i need to get to achieve this number. And with the peices that i mentioned above, would my bottom end be able to withstand the numbers i want to achieve.
Thanks guys

#78467 That combo would work. but you don't have to go low comp. low comp=more boost to get more power. What pistons have you been looking at? like brand and such?

Chrome should work, but who will be tuning it?

#78484 Ive been looking at the brian crower sets and the JE SRP pistons. the brian crower's compression ratio is 10:5:1 and the je's are 10:7:1.
And about tuning, Im not sure, we had a shop up here that would have done it, but its closed now.
So finding someone to tune it is going to be a challange.
Thanks for the help man. Let me know what you think

#78486 whith the compression you whant to run you whant to make sure you get a real good tunner because you whont have a lot of room for mistakes but your goal will be easily reached.

#78487 What would be a super safe compression to run? And again, thanks for the fast responses guys

If it were me i would check into wiseco pistons, with eagle rods. It's one of the cheapest set up's to do, and they work great. Thats what i just used for my d16. but a buddy of mine is using wiseco/eagle set up in his SFWD race car and he hasn't had a problem. his integra is making 890hp.

but that is also with a good tuner. so be sure you're going to have someone on hand that can tune properly.

I think you'll be fine with any c/r, as long as you have a good tuner.

#88012 i'd recomend the 9.1.1 compression ratio piston or 8.1.1if you want 400hp +, the 9.1.1 for the tuning more of an open window for error and adjustment in tune and some rc750cc

#88215 crome will be fine, and 400 is very easy to reach with that motor. 8-9 compression is just fine either way for that power level.
